This sounds like a quadratic equation of f(x)=x^2, thus, the range is:

The values of a, b, c are 152°, 28°, 152° respectively.

Angles around a point describes the sum of angles that can be arranged together so that they form a full turn.

The sum of angles at a point will give 360°.

This means that a + b + c + 28 = 360

c +28 = 180° ( angle on a straight line)

c = 180 -28

c = 152°

c = a( alternate angles are equal)

therefore the value of a = 152°

b = 28( alternate angles are equal)

therefore the value of b is 28

therefore the values of a, b, c are 152°, 28°, 152° respectively

Answer:

Step-by-step explanation:

The greatest common factor of 12 and 80 is 12, so we can use the distributive property to factor that out.

Identify the greatest common factor (GCF). In this case, it's 12.

Rewrite the expression so the GCF is outside of the parentheses. 12 + 80 = 12(1 + 80/12).

Simplify the expression inside the parentheses. 1 + 80/12 = 7.

Substitute the simplified expression back into the original equation. 12 + 80 = 12(7).

Simplify the expression. 12 + 80 = 84.

Therefore, 12 + 80 = 84 after applying the distributive property to factor out the greatest common factor of 12.

Total number of outcomes in rolling a die 3 times = \(6^3\)  =216

What is outcome of an event?

Suppose an event is happening. The result of the event is called outcome of the event.

For example : let the event be throwing of a die. One of the outcome of the event is getting a 4 on the die

Number of outcomes of rolling a die first time = 6

Number of outcomes of rolling the die second time = 6

Number of outcomes in rolling a die third time = 6

Total number of outcomes in rolling a die 3 times = \(6 \times 6 \times 6\)

                                                                                   = \(6^3\)

If the absolute value of the computed t-score is greater than the critical value, then the correlation is statistically significant at α = 0.05, two tails.

To determine which correlations are statistically significant with α = 0.05, two tails, we need to compare the computed Pearson correlation coefficient (r) to the critical value from the t-distribution.

In a sample of n = 18 pairs of x and y values, the significance of the correlation is assessed using hypothesis testing. The null hypothesis states that there is no correlation between the variables (ρ = 0), while the alternative hypothesis suggests a significant correlation (ρ ≠ 0).

To test the hypothesis, we calculate the sample correlation coefficient (r) and then convert it to a t-score using the formula

t = (r × \(\sqrt(n-2)\)) / \(\sqrt(1 - r^2)\)

The degrees of freedom for the t-distribution are df = n - 2.

Next, we compare the absolute value of the computed t-score to the critical value of the t-distribution with α/2 = 0.025 significance level.

If the absolute value of the t-score exceeds the critical value, we reject the null hypothesis and conclude that the correlation is statistically significant.

The critical value for α = 0.05, two tails, depends on the degrees of freedom (df = 16 in this case) and can be obtained from a t-table or statistical software. If the absolute value of the computed t-score is greater than the critical value, we can say that the correlation is statistically significant at α = 0.05, two tails.

Answer:

Answer:

100

Step-by-step explanation:

How many students attended the tournament?

The simultaneous equations that would be used to solve this question is:

10a + 7s = 4,200 equation 1

a + s = 450 equation 2

Where:

a = number of adults

s = number of students

The elimination method would be used to solve the equations.

Multiply equation 2 by 10

10a + 10s = 4500 equation 3

3s = 300

Divide both sides of the equation by 3

s = 300 / 3

s = 100

Answer:

100 students who attended the tournament.

Step-by-step explanation:

Let's use algebra to solve the problem. Let's call the number of students who attended the tournament "s" and the number of adults who attended the tournament "a". Then we can write two equations based on the information given:

s + a = 450 (equation 1)

7s + 10a = 4200 (equation 2)

Equation 1 represents the total number of people who attended the tournament, which is 450. Equation 2 represents the total amount of money collected in ticket fees, which is $4,200.

To solve for "s", we can use elimination or substitution. Let's use elimination. We can multiply equation 1 by -7 to get:

-7s - 7a = -3150 (equation 3)

Now we can add equation 3 to equation 2:

-7s - 7a + 7s + 10a = -3150 + 4200

Simplifying the left side and solving for "a", we get:

3a = 1050

a = 350

So there were 350 adults who attended the tournament. We can substitute this value back into equation 1 to solve for "s":

s + 350 = 450

s = 100

Therefore, there were 100 students who attended the tournament.

Step-by-step explanation:

Answer:

a) \(\sqrt{56\) → Definitely not undefined because 56 is a positive real number

b) \(-\sqrt{56\) → Definitely not undefined because 56 is a positive real number (and the negative sign is not under the square root)

c) \(\sqrt{-56\) → Definitely undefined because -56 is a negative number

__

We know that there is no real square root of a negative number because nothing multiplied by itself results in a negative number.

__

d) \(\sqrt h\) → Could be undefined because we don't know the value of \(h\); it could be positive or negative

e) \(-\sqrt {h\) → Could be undefined because we don't know the value of \(h\); it could be positive or negative (and the negative sign doesn't affect this because it is outside the square root)

f) \(\sqrt{-h\) (when \(h\) is positive) → Definitely undefined because the value inside of the square root is negative (a negative times a positive is a negative)

The value of "p" will be "0.002".

According to the question,

By subtracting "0.25p" from both sides, we get

→ \(100+0.05p-0.25p=0.25p-0.25p\)

                 \(100-0.2p=0\)

                            \(100=0.2p\)

                               \(p = \frac{0.2}{100}\)

                                  \(= 0.002\)

Answer:

A pound of jelly beans costs $4, and a pound of gummy worms costs $6

Step-by-step explanation:

Let

Cost of one pound of Jelly beans = x

Cost of one pound of Gummy worms = y

Making equations from the statements:

Lillian bought 4 pounds of jelly beans and 3 pounds of gummy worms for $34: \(4x+3y=34\)

Kelsey bought 5 pounds of jelly beans and 3 pounds of gummy worms for $38: \(5x+3y=38\)

Solving both equations we can found cost of candies.

Let:

\(4x+3y=34--eq(1)\\5x+3y=38--eq(2)\)

Subtracting both equations to find value of x

\(4x+3y=34\\5x+3y=38\\- \ \ \ - \ \ \ \ -\\------\\-x=-4\\x=4\)

So,we get value of x=4

Now putting value of x in eq(1) to find value of y

\(4x+3y=34\\4(4)+3y=34\\16+3y=34\\3y=34-16\\3y=18\\y=18/3\\y=6\)

We get value of y=6

Cost of one pound of Jelly beans = x = 4

Cost of one pound of Gummy worms = y = 6

A pound of jelly beans costs $4, and a pound of gummy worms costs $6

Step-by-step explanation:

b) The mean is 19.

c) The standard deviation is 0.974.

d) The binomial probability is 20.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

n = 20,  p = 0.95,  q = 1 - 0.95 = 0.05

a)  There are only two results per shot and they are independent of each other. Each pitch is independent of the outcome of the other pitches.

b) To calculate the mean of X.

{ E(x) = np }

So, E(x) = 95% of 20

             = 19

c) The Standard Deviation is √npq

= √95/10

= 0.974

d) The binomial probability

p(x = 19) = 20! / 19!(20-19)!

Step-by-step explanation:

In order to find the small standard error, there is always need of a complete set which is called the large sample.

If tried to do a small or repeating sample, you will most likely not get an error and you could get a repetition. If you do a population sample, you wont get accurate results at all.

Therefore, a good way to get a small standard error is to use a large sample. Hope this helps!
