Answer:

x = 121°

Step-by-step explanation:

∠ 1 + 115° = 180°

∠ 1 = 180 - 115

∠ 1 = 65°

∠ 2 + 304° = 360°

∠2 = 360 - 304

∠ 2 = 56°

∠ 1 + ∠ 2 + ∠ 3 = 180°

65° + 56 ° + ∠ 3 = 180°

∠3 = 180 - 65 - 56

∠ 3 = 59°

∠3 + x = 180°

59° + x = 180°

x = 180 - 59

x =  121 °

The method that could be used instead of cross multiplication to solve the equation *3-3x+5 is distributing x + 3 and then 3x + 5 to both sides of the equation.

Instead of using cross multiplication, one alternative method to solve the equation *3-3x+5 is to distribute x + 3 and then 3x + 5 to both sides of the equation.

To explain this method, let's consider the equation step by step:

Original equation: *3-3x+5

Cross multiplication: 5(x+3) = 2(3x+5)

Distributive property: 5x + 15 = 6x + 10

Subtraction property of equality: 5x - 6x = 10 - 15

Simplification: -x = -5

Multiplication property of equality: (-1)(-x) = (-1)(-5)

Simplification: x = 5

Now, instead of cross multiplication, we can distribute x + 3 and then 3x + 5 to both sides of the equation:

Original equation: *3-3x+5

Distributive property: 5(x + 3) = 2(3x + 5)

Expanding the expressions inside the parentheses:

5x + 15 = 6x + 10

Now we can proceed with solving the equation as before:

Subtraction property of equality: 5x - 6x = 10 - 15

Simplification: -x = -5

Multiplication property of equality: (-1)(-x) = (-1)(-5)

Simplification: x = 5

By distributing x + 3 and 3x + 5 to both sides of the equation, we obtain the same result as the original method. This alternative method is another way to solve the equation without using cross multiplication.

Step-by-step explanation: We can solve the equation |2x + 3| = 7 by

first splitting things up into two separate equations.

The first equation will look just like the original problem,

minus the absolute value signs and we have 2x + 3 = 7.

The second equation will look just like the first, only the right

side will be changed to a negative and we have 2x + 3 = -7.

Now solve each equation from here.

In our first equation, subtract 3 from both sides to get 2x = 4.

Then divide both sides by 2 and x = 2.

In our second equation, subtract 2 from both sides to get 2x = -10.

Now, divide both sides by 2 and we have x = -5.

So either x = 2 or x = -5.

Answer:

x^2 + 10x + 25; (x + 5)^2.

Step-by-step explanation:

When we're talking about line segments, we just have to find the sum of the two parts of the line segment to find the value of the whole. In this case, we have x^2 + 25, and 10x. So, we add them together.

x^2 + 25 + 10x

= x^2 + 10x + 25

Since this can be immediately factored into (x + 5)^2, you have your answer.

a) There is not enough evidence to conclude that cars get significantly better fuel economy with premium gasoline.

In order to test the belief that premium gasoline provides better fuel economy, a study was conducted using 10 cars from a company fleet. Each car was randomly assigned either regular or premium gasoline, and the mileage for each tankful was recorded. The data was analyzed to determine if there is a significant difference in fuel economy between the two types of gasoline.

To evaluate this, a paired t-test can be used since the same cars were tested with both types of gasoline. The null hypothesis would be that there is no difference in fuel economy between regular and premium gasoline, while the alternative hypothesis would be that there is a significant difference.

The results of the study would be analyzed using the appropriate statistical test, such as a paired t-test, to determine the p-value. If the p-value is less than the chosen significance level (e.g., 0.05), then there would be evidence to reject the null hypothesis and conclude that there is a significant difference in fuel economy.

The equation that describes the Demand side of the coffee market is QD = 17 - 3P + 4. The equation that describes the Supply side of the coffee market is QS = 1 + 5P - 4R .

To find the equilibrium price of coffee, we will equate both demand and supply functions:

17 - 3P + 2R = 1 + 5P - 4R 8P

= 16 P

= $2.

The equilibrium price of coffee is $2. To find the equilibrium quantity of coffee, we will substitute P in either demand or supply function: QD = 17 - 3($2) + 2($1)

= 11 QS

= 1 + 5($2) - 4($1)

= 7

The equilibrium quantity of coffee demanded and supplied is 7.

When tea is given for free, the demand curve shifts to the left, i.e., there is a decrease in the quantity demanded of coffee. So, there will be a change in Quantity Demanded. Since the demand for coffee will decrease while the supply remains constant, the price of coffee will decrease. The quantity of coffee sold will decrease. Hence, the answer to the above question will be decreased.

Step-by-step explanation:

*A triangle has an interior angle of 180 degrees

We know that one of the angle is 112 degree

180 - 112 = 68 degrees

We also know that the triangle is an isosceles triangle which means both sides and both angles are the same ( we can determine that it's an isosceles because of the two lines)

68 / 2 = 34

R = 34 degrees

T = 34 degrees

Step-by-step explanation:

profit = revenue - expenses

revenue = $15 per hour = $15 * number of hours (n) = $15 * n

expenses = $490 + $45 + $65 = $600

we want profit to be 600 or more

15 * n - 600 = profit

profit ≥ 600

15 * n - 600 ≥ 600

add 600 to both sides to isolate the variable and its coefficient

15 * n ≥ 1200

divide both sides by 15 to isolate the variable

n ≥ 80

Answer:

A= -17

Step-by-step explanation:

A +-21 = -38

    +21     +21

-38+21= -17

A= -17

Answer:

a = -17

Step-by-step explanation:

To solve this, we need to get A alone:

A + -21 = -38

—- +21- +21

Remember, when you do something to one side, you need to do the same thing to the other side.

Now:

A = -17!

To check:

-17 + -21 = -38

Therefore, A = -17

-3x + y = 2 Equation (1)

7x -8y = 1 Equation (2)

Let us solve the system of equations with the elimination method.

-24x + 8y = 16 (Multiplying the equation 1 by 8)

+ 7x - 8y = 1 (Adding the equation 2 to the last form of the equation 1)

------------------

-17x = 17 (Adding like terms)

x = 17/(-17) ( Dividing by -17 on both sides of the equation)

x= -1

Replacing x=-1 in the equation 1,we have:

-3(-1) + y = 2

3 + y = 2 (Multiplying and using the sign rules)

y = 2- 3 (Subtracting 3 from both sides of the equation)

y = -1 (Subtracting)

The answers are x=-1 and y=-1

Bob has 63 quarters, based on the given information that he has a total of 90 dimes and quarters with a total value of $18.45.

Let's assume Bob has 'x' quarters. Since the total number of dimes and quarters is 90, we can represent the number of dimes as 90 - x.

The value of each quarter is $0.25, and the value of each dime is $0.10. The total value of the coins is given as $18.45.

We can set up the equation:

0.25x + 0.10(90 - x) = 18.45

Simplifying the equation:

0.25x + 9 - 0.10x = 18.45

0.15x + 9 = 18.45

0.15x = 9.45

x = 9.45 / 0.15

x ≈ 63

Therefore, Bob has approximately 63 quarters.

Probability:

Probability means the possibility of happening the particular event. So, it can be written as the fraction of possible event by the total number of event.

Given,

The probability a D-Link network server is down is 0.10.

Here we need to find if you have three independent servers, what is the probability that at least one of them is operational.

Let D be an event that a D-Link network server is down.

It is given that the probability that a D-Link network server is down is

=> P(D) = 0.10

The number of independent servers

=> (n) = 3

The probability that none of the servers is working is

=>P(None) = P(D) x P(D) x P(D)

=> P(None) = 0.10 x 0.10 x 0.10

=> P(None) = 0.001

The probability that at least one of them is operational is given as

The probability of randomly generating the zip code 39372 is:
1 / 35 ≈ 0.0286 or 2.86%

To find the probability that a randomly generated zip code is the number 39372, we need to determine the number of favorable outcomes (one) divided by the total number of possible outcomes.

In this case, the total number of possible outcomes is the number of permutations of the digits 3, 7, 3, 9, 5, 7, 2, and 3.

To calculate this, we use the formula for permutations with repeated elements:

n! / (n1! * n2! * ... * nk!)

Where n is the total number of elements, and n1, n2, ..., nk are the counts of each repeated element.

In this case, n = 7, n1 = 3 (for the repeated digit 3), and n2 = 2 (for the repeated digit 7).

So, the total number of possible outcomes is:

7! / (3! * 2!) = 7 * 6 * 5 * 4 * 3 * 2 * 1 / (3 * 2 * 1 * 2 * 1) = 35

Step-by-step explanation:

The midpoint has coordinates (19,19) as per the midpoint formula.

The statement is false.

The statement is false. The midpoint of the segment joining two points is determined by taking the average of their x-coordinates and the average of their y-coordinates. In this case, the two given points are (0,0) and (38,38).

To find the x-coordinate of the midpoint, we take the average of the x-coordinates of the two points:

(x1 + x2) / 2

= (0 + 38) / 2

= 38 / 2

= 19

Therefore, the x-coordinate of the midpoint is 19, which matches the statement. However, to determine if the statement is true or false, we also need to check the y-coordinate.

To find the y-coordinate of the midpoint, we take the average of the y-coordinates of the two points:

(y1 + y2) / 2

= (0 + 38) / 2

= 38 / 2

= 19

The y-coordinate of the midpoint is also 19. Therefore, the coordinates of the midpoint are (19,19), not 19 as stated in the statement. Since the midpoint has coordinates (19,19), the statement is false.

Answer:

(2,4)

Step-by-step explanation:

Factors that could result in an increase in the range of the confidence interval include a larger sample standard deviation, a smaller sample size, or a lower confidence level

(a) To create a 95% confidence interval for the population mean, we can use the formula:

Confidence Interval = sample mean ± (critical value * (sample standard deviation / sqrt(sample size)))

Since the sample size is 41, the sample mean is 670 tonnes, and the sample standard deviation is 103.2, we need to determine the critical value for a 95% confidence level. The critical value can be obtained from the t-distribution table or using statistical software. Assuming a t-distribution is appropriate for this sample size, the critical value for a 95% confidence level with 40 degrees of freedom is approximately 2.021.

Substituting the values into the formula, the confidence interval is:

Confidence Interval = 670 ± (2.021 * (103.2 / sqrt(41)))

(b) The interpretation of the confidence interval is that we are 95% confident that the true population mean falls within the calculated interval. In this case, the confidence interval represents a range of values around the sample mean (670 tonnes) within which the population mean is likely to be located.

A larger sample standard deviation indicates greater variability in the data, which leads to a wider range of possible values for the population mean. A smaller sample size reduces the precision of the estimate, resulting in a wider confidence interval. Similarly, a lower confidence level, such as 90% instead of 95%, would also widen the confidence interval to capture a larger range of possible values for the population mean.

Therefore, the strength of the electric field is 18 N/C to the left at the position indicated by the dot.

When we have to determine the strength and direction of the electric field at the position indicated by the dot in (figure 1), we can use the formula \(E = kq/r²\) whereE represents the electric field strength,k represents Coulomb's constant, which is 9 x 10^9 Nm²/C²,q represents the charge,r represents the distance between the charges.The dot lies on the x-axis 4.0 cm from a charge of -8.0 nC. To determine the electric field strength and direction, we need to know the direction of the electric field at the dot that results from the -8.0 nC charge. The electric field would be positive to the left and negative to the right when using Coulomb's law, and it would be positive when the charge is negative.

The electric field, however, is a vector quantity that has both magnitude and direction, and we must consider the forces in both the x and y directions.We have -8.0 nC on the x-axis 4.0 cm from the dot. We'll use the electric field equation to determine the electric field generated by this charge:

\(|E1| = k|q|/r²|E1| = 9 x 10^9 * 8 x 10^-9 / (4 x 10^-2)²|E1| = 18 N/C\) The electric field is negative because the charge is negative, which means it points towards the charge. Since the dot lies to the right of the charge, the electric field points to the left. This can be seen in the following figure: Electric field due to charge QThe electric field due to -8 nC charge at the dot is 18 N/C to the left.

Using the compound interest formula, we found that the account with the greater balance after 5 years is yours and after 15 years is the friend's.

What is compound interest?

Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit. Compound interest is calculated for an amount based on both the principal and cumulative interest. The primary distinction between compound and simple interest is this. It is the interest that has been calculated using both the principal and the interest that has accrued over the preceding period.

First case

Amount deposited P = $3000

Rate of interest r = 3.8%

Continuous compounding is done.

For continuous compounding,

Amount P(t) after time t is:

\(P(t)=Pe^{rt}\)

After 5 years is:

\(P(5)=Pe^{r5} = 3000 * e^{0.038*5}\) = $3630

After 15 years is:

\(P(15)=Pe^{r15} = 3000 * e^{0.038*15}\) = $5304.80

2nd case

Amount deposited P = $2800

Rate of interest r = 4.5% = 0.045

Compounded monthly.

n = 12

Amount A after time t is:

\(A = P(1 + \frac{r}{n})^{nt}\)

Amount after 5 years

A = \(2800(1 + \frac{0.045}{12})^{12*5}\) = $3505.03

Amount after 15 years

A = \(2800(1 + \frac{0.045}{12})^{12*15}\) = $5492.35

Therefore using the compound interest formula, we found that the account with the greater balance after 5 years is yours and after 15 years is the friend's.
