Answer:

The 80% confidence interval for the average net change in a student's score after completing the course is (15.4, 26.3).

Step-by-step explanation:

The net change in 7 students' scores on the exam after completing the course are:

S = {37 ,12 ,12 ,17 ,13 ,32 ,23}

Compute the sample mean and sample standard deviation as follows:

[tex]\bar x=\frac{1}{n}\sum x=\frac{1}{7}\times 146=20.857\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}}=\sqrt{\frac{1}{7}\times 622.8571}=10.189[/tex]

As the population standard deviation is not known, a t-interval will be formed.

Compute the critical value of t for 80% confidence interval and 6 degrees of freedom as follows:

[tex]t_{\alpha/2, (n-1)}=t_{0.20/2, (7-1)}=t_{0.10,6}=1.415[/tex]

*Use a t-table.

Compute the 80% confidence interval for the average net change in a student's score after completing the course as follows:

[tex]CI=\bar x\pm t_{\alpha/2, (n-1)}\times\frac{s}{\sqrt{n}}[/tex]

     [tex]=20.857\pm 1.415\times\frac{10.189}{\sqrt{7}}\\\\ =20.857\pm 5.4493\\\\=(15.4077, 26.3063)\\\\\approx (15.4,26.3)[/tex]

Thus, the 80% confidence interval for the average net change in a student's score after completing the course is (15.4, 26.3).

Answer:

58

Step-by-step explanation:

All three angles of a triangle have to add up to 180. Given this we can do the following problem:

180-34-88 = 58

Answer:

38.04

Step-by-step explanation:

6200/163= 38.036809816

Since after the 3 is a 6 which is over 5 you can round the 3 up to a 4 and cut everything else off.

Hope this helps. Plz give brainliest.

6200 divided by 163 is equal to 38 with a remainder of 6.

We have,

The concept used to divide 6200 by 163 is a long division.

Long division is a method of dividing two numbers by repeatedly subtracting multiples of the divisor from the dividend until the remainder becomes smaller than the divisor.

It involves dividing digit by digit, starting from the leftmost digits of the dividend and moving towards the right.

Now,

To divide 6200 by 163, we perform a long division.

Here's how it works:

       38

  __________

163| 6200

Common difference = Second term - first term

Common difference = 1 - 10

Common difference = - 9

Answer: Eric earned $7

Step-by-step explanation:

Let's define:

R = money that Robert earned.

E = Money that Eric earned.

Now we want to find how much money did Eric earn.

We know that:

R = $10 = 2*E - $4

Whit this equation, we can find the value of E. So we must isolate the variable E in one side of the equation:

2*E = $10 + $4 = $14

E = $14/2 = $7

Answer:

x = 4

Step-by-step explanation:

First, you subtract 1 from both sides, giving you 3x = x + 8

Then you subtract 1x from both sides, so 2x = 8

Divide the 2 from both sides which leaves you with the answer, x = 4

Step-by-step explanation:

Answer:

1.0

Step-by-step explanation:

this is a aplication of the terms

x = measure of the angle

180 - x = measure of supplement {supplementary angles add up to 180}

x = 74(180 - x) {measure of the angle is 174 times the supplement}

x = 13,320 - 74x {used distributive property}

75x = 13,320 {added 74x to each side}

x = 177.6 {divided each side by 177.6}

the angle is 177.6

the supplement is 2.4

Answer:

122 Degrees

Step-by-step explanation:

Since we are given that angle 1 and 2 make a linear pair:

angle 1 + angle 2 = 180 degrees ----------------------------(1)

We have also been told that angle 2 is 6 more than twice the measure of angle 1

Which means: angle 2 = (2*angle1)  + 6 -------------------(2)

From putting the value of angle 2 in (1) from (2)

angle 1 + 2*angle 1 + 6 = 180

3*angle 1 = 174

angle 1 = 58 degrees -----------------------(3)

From (1) and (3):

angle 2 + 58 = 180

angle 2  = 122 degrees

Therefore, the measure of angle 2 is 122 degrees

Answer:

x = 1

Step-by-step explanation:

Input values are x-values plotted on the x-axis, while output values are the y-values plotted on the y-axis.

The question is simply asking that, which value of x will give us the same y-value for the two functions graphed above.

The x value that will give us the same y-value for both functions is the point where the line of both functions intercept. At that point, when x = 1, y = 1, in both functions.

Therefore, the input value of x = 1, will give an output value of y = 1, for the two functions on the graph.

Answer:

55

Step-by-step explanation:

This is the equation of a parabola. To make things simpler, we can replace [tex]h[/tex] with [tex]y[/tex] and [tex]t[/tex] with [tex]x[/tex]. Therefore, [tex]y=-5x^2+30x+10[/tex]. Because the coefficient of the [tex]x^2[/tex] term is negative, we know the parabola points down, and the maximum height is the vertex. The x coordinate of the vertex of a parabola can be found with the equation [tex]-\frac{b}{2a}[/tex], or [tex]-\frac{30}{-10} = 3[/tex]. Plugging in [tex]3[/tex] into the equation gives us [tex]y = -5(3)^2+30(3)+10 = \boxed{55}[/tex]
