Based on executing the test in Question 5, what would you conclude, given a margin of error of 5%? Group of answer choices We re
Harman [31]

People often draw hypothesis in research.  Based on executing the test in Question 5, We reject the null hypothesis; the mean delivery time is different for every day of the week.

<h3>Why do we reject the null hypothesis?</h3>

Note that if the p-value of an experiment (Like the one above) is less than or found to be equal to the significance level of your test, one can reject the null hypothesis.

By that, we known that the data is in favors the alternative hypothesis. Hence the results gotten by you are statistically significant. If your p-value is found to be greater than your significance level, you then fail to reject the null hypothesis.

In circle N with m \angle MNP= 48m∠MNP=48 and MN=16MN=16 units find area of sector MNP. Round to the nearest hundredth.
Dafna11 [192]

Answer:

A=107 square\ unit

Step-by-step explanation:

From the question we are told that:

 \angle MNP= 48m

 \angle  MN=16 unit

Generally the equation for Area of a sector A is mathematically given by

 A=\frac{\theta}{360}*\pi*r^2

 A=\frac{48}{360}*3.14*16^2

 A=107.18 square\ unit

 A=107 square\ unit

Which equation represents a graph with a vertex at (–3, 2)?
lesya [120]

<u>We will proceed to find the equations in the vertex form in each case</u>

<u>Part a)</u> y= 4x^{2}+24x+38

Group terms that contain the same variable, and move the constant to the opposite side of the equation

y-38= 4x^{2}+24x

Factor the leading coefficient

y-38= 4(x^{2}+6x)

Complete the square. Remember to balance the equation by adding the same constants to each side

y-38+36= 4(x^{2}+6x+9)

y-2= 4(x+3)^{2}

y= 4(x+3)^{2}+2

<u>the vertex is the point (-3,2)</u>

<u>Part b)</u>  y=4x^{2}-24x+38

Group terms that contain the same variable, and move the constant to the opposite side of the equation

y-38= 4x^{2}-24x

Factor the leading coefficient

y-38= 4(x^{2}-6x)

Complete the square. Remember to balance the equation by adding the same constants to each side

y-38+36= 4(x^{2}-6x+9)

y-2= 4(x-3)^{2}

y= 4(x-3)^{2}+2

<u>the vertex is the point (3,2)</u>

<u>Part c) </u> y=4x^{2}+12x+2

Group terms that contain the same variable, and move the constant to the opposite side of the equation

y-2= 4x^{2}+12x

Factor the leading coefficient

y-2= 4(x^{2}+3x)

Complete the square. Remember to balance the equation by adding the same constants to each side

y-2+9= 4(x^{2}+3x+2.25)

y+7= 4(x+1.5)^{2}

y= 4(x+1.5)^{2}-7

<u>the vertex is the point (-1.5,7)</u>

<u>Part d)</u> y=4x^{2}+16x+13

Group terms that contain the same variable, and move the constant to the opposite side of the equation

y-13= 4x^{2}+16x

Factor the leading coefficient

y-13= 4(x^{2}+4x)

Complete the square. Remember to balance the equation by adding the same constants to each side

y-13+16= 4(x^{2}+4x+4)

y+3= 4(x+2)^{2}

y= 4(x+2)^{2}-3

<u>the vertex is the point (-2,-3)</u>

therefore

<u>the answer is </u>

y= 4x^{2}+24x+38
