Answer:

y = 3/5x - 1

Step-by-step explanation:

y = mx + b

m = slope

m = 3/5

to find the y - intercept we have to make x = 0 by adding or subtracting

in this case it is +5

add five to both x and y

\((-5, -6) + (5, 5) = (0, -1)\)

the y intercept focuses on what y is when x is 0

the y intercept in this case is -1

Answer:

Step-by-step explanation:

You just count up.

We can simplify cosec(t)tant(t) to sec(t). A trigonometric function is a mathematical function that relates the angles of a triangle to the ratios of its sides.

The most common trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

To simplify the expression cosec(t)tant(t), we need to use the trigonometric identity:

cosec(t) = 1/sin(t)

tant(t) = sin(t)/cos(t)

Substituting these expressions into the original expression, we get:

cosec(t)tant(t) = (1/sin(t))(sin(t)/cos(t))

The sin(t) term in the numerator and denominator cancel out, leaving:

cosec(t)tant(t) = 1/cos(t)

Recalling the definition of secant, sec(t) = 1/cos(t), we can express the simplified expression as:

cosec(t)tant(t) = 1/sec(t)

Therefore, we can simplify cosec(t)tant(t) to sec(t).

good luck :)

\(4 \times {16}^{ - (y - 2) } \times {4}^{ - y} = ({4})^{ ({3})^{ (- 2y - 1)} } \\ \)

\(4 \times ({4})^{ ({2})^{(y - 2)} } \times {4}^{ - y} = {4}^{ - 6y - 3} \)

\(4 \times {4}^{(2y - 4)} \times {4}^{ - y} = {4}^{ - 6y - 3} \)

\( {4}^{1 + 2y - 4 - y} = {4}^{ - 6y - 3} \\ \)

\( {4}^{y - 3} = {4}^{ - 6y - 3} \)

Thus ;

\(y - 3 = - 6y - 3\)

Plus sides 3

\(y - 3 + 3 = - 6y - 3 + 3\)

\(y = - 6y\)

Plus sides 6y

\(y + 6y = - 6y + 6y\)

\(7y = 0\)

Divided sides by 7

\( \frac{7}{7}y = \frac{0}{7} \\ \)

\(y = 0\)

Step-by-step explanation:

100 * 5 + 2 = 505

Answer:

To find the 100th term of the sequence, we need to use the recursive rule and iterate it 99 times, since we are starting at the first term and need to get to the 100th term.

The recursive rule is given as 5, which means each term in the sequence is equal to the previous term times 5. Therefore:

The first term is 2.

The second term is 2 * 5 = 10.

The third term is 10 * 5 = 50.

The fourth term is 50 * 5 = 250.

And so on...

Iterating this rule 99 times gives us:

The 100th term is 2 * 5^99, which is approximately equal to 6.33825300114 × 10^66.

Therefore, the 100th term of the sequence starting with 2 and with a recursive rule of 5 is approximately 6.33825300114 × 10^66.

The system of equations is

125a + 65s = 1200

140a + 50s = 1230

What is an equation?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

125a + 65s = 1200

140a + 50s = 1230

-3500a - 1820s = -33600  

3500a + 1250s = 30750

-570s = -2850

s = $5

125a + 65(5) = 1200

\(Mean = 344\)

Step-by-step explanation:

Given

\(Population = 1013\)

Let p represents the proportion of those who worry about identity theft;

\(p = 66\%\)

Required

Mean of those who do not worry about identity theft

First, the proportion of those who do not worry, has to be calculated;

Represent this with q

In probability;

\(p + q = 1\)

Make q the subject of formula

\(q = 1 - p\)

Substitute \(p = 66\%\)

\(q = 1 - 66\%\)

Convert percentage to fraction

\(q = 1 - 0.66\)

\(q = 0.34\)

Now, the mean can be calculated using:

\(Mean = nq\)

Where n represents the population

\(Mean = 1013 * 0.34\)

\(Mean = 344.42\)

\(Mean = 344\) (Approximated)

Literally have the same question on my test and i dont know if i got it right or wrong. I know it has nothing to do with this :/ im sorry.

Answer:

55°

Step-by-step explanation:

In the triangle towards the bottom-left, we can see that it is an iscosceles triangle, which means that the two angles opposite of those two sides are also equal. Along with this, a triangle will also only have 180° for the sum of all of its angles.

When you put another x in the angle next to the 37°, you get an equation similar to:

\(x+x+37+33 = 180\\2x + 70 = 180\\2x = 110\\x = 55\)

x in this case will then be 55 degrees.

The coordinates of the reflected point P' will be (4, -3).

When a point is reflected over the x-axis, its y-coordinate changes sign.

In this case, the point P has coordinates (4,3).

To reflect it over the line x=3, we need to keep its x-coordinate the same and change its y-coordinate to its opposite.

So, the x-coordinate of the reflected point will still be 4, but the y-coordinate will become -3.

Therefore, the coordinates of the reflected point P will be (4, -3).

The rate of interest is 73%.

What is the annual rate?

The term annual percentage rate of charge refers to the interest rate for an entire year rather than just a monthly fee or rate as applied on a loan, mortgage loan, credit card, etc. It can also be referred to as a nominal APR or an effective APR. It is an annual rate of a finance charge.

Given that 1 dollar to grow to X dollars in 2 years is given by the formula X = (1+r) ².

A dollar to triple in 2 years.

Thus putting X = 3 in X = (1+r) ²

3 = (1+r) ²

Take square root on both sides:

√3 = 1 + r

Subtract 1 from both sides:

r = √3 - 1

r = 0.73

(c) 15i + 4b ≥ 100 inequality represents this scenario.

To represent the scenario described in the problem, we need to use an inequality that relates the amount of money Emily spends on ink and brushes to the total amount of money she has available. Let's call the amount of ink Emily buys "x" and the number of brushes "y". Then the total amount of money she spends is:

Total cost = 8x + 18y

We want to know when this total cost is less than or equal to $100, so we can write:

8x + 18y ≤ 100

This inequality means that the total cost of ink and brushes must be less than or equal to the amount of money Emily has available. Therefore, the answer is (c) 15i + 4b ≥ 100.

The solution to the system of equations is x = 1 and y = -3.

To solve the system of equations using the substitution or elimination method, let's start with the substitution method.

Given equations:

y = 4x - 7

4x + 2y = -2

We'll solve equation 1) for y and substitute it into equation 2):

Substituting y from equation 1) into equation 2):

4x + 2(4x - 7) = -2

4x + 8x - 14 = -2

12x - 14 = -2

Now, we'll solve this equation for x:

12x = -2 + 14

12x = 12

x = 12/12

x = 1

Now that we have the value of x, we can substitute it back into equation 1) to find y:

y = 4(1) - 7

y = 4 - 7

y = -3

Therefore, the solution to the system of equations is x = 1 and y = -3.

Answer:

a) Null and alternative hypothesis:

\(H_0: \pi=0.1\\\\H_a:\pi>0.1\)

b) A Type I error is made when a true null hypothesis is rejected. In this case, it would mean a conclusion that the proportion is significantly bigger than 10%, when in fact it is not.

c) The consequences would be that they would be more optimistic than they should about the result of the investment, expecting a proportion of students that is bigger than the true population proportion.

d) A Type II error is made when a false null hypothesis is failed to be rejected. This would mean that, although the proportion is significantly bigger than 10%, there is no enough evidence and it is concluded erroneously that the proportion is not significantly bigger than 10%

e) The consequences would be that the investment may not be made, even when the results would have been more positive than expected from the conclusion of the hypothesis test.

Step-by-step explanation:

a) The hypothesis should be carried to test if the proportion of students that would eat there at least once a week is significantly higher than 10%.

Then, the alternative or spectulative hypothesis will state this claim: that the population proportion is significantly bigger than 10%.

On the contrary, the null hypothesis will state that this proportion is not significantly higher than 10%.

This can be written as:

\(H_0: \pi=0.1\\\\H_a:\pi>0.1\)
