Testing the hypothesis, we have that since the p-value of the test is 0 < 1, our response is that the presumption underestimates the proportion of defective parts.

At the null hypothesis, we test if the proportion of defectives is of at most 1%, that is:

[tex]H_0: p \leq 0.01[/tex]

At the alternative hypothesis, we test if the proportion of defectives is of more than 1%, that is:

[tex]H_1: p > 0.01[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

From the sample, we have that:

[tex]n = 500, \overline{p} = \frac{15}{500} = 0.03[/tex]

Thus, the value of the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.03 - 0.01}{\sqrt{\frac{0.01(0.99)}{500}}}[/tex]

[tex]z = 4.49[/tex]

The p-value of the test is the probability of finding a sample proportion above 3%, which is 1 subtracted by the p-value of z = 4.49.

z = 4.49 has a p-value of 1.

1 - 1 = 0.

The p-value of the test is 0 < 1, which means that our response is that the presumption underestimates the proportion of defective parts.

Answer:

90 degrees

Step-by-step explanation

This is because the graph quadrant shape goes in a C. 1 is the top right and 4 is the top left.

This is one way of doing it.

We want to get the function into vertex form.  

y = x2 - 4x + 2                  Subtract 2 from both sides.

y - 2 = x2 - 4x                   Add (-4/2)2 , or 4, to both sides.

y - 2 + 4 = x2 - 4x + 4       Now that the right hand side is a perfect square trinomial, factor it.

y + 2 = (x - 2)(x - 2)          

y + 2 = (x - 2)2                  Subtract 2 from both sides.

y = (x - 2)2 - 2

When the equation is in this form, we can see that this is the graph of y = x2 shifted to the right 2 units and shifted down 2 units. The vertex is at (2, -2). So plot the first point at (2, -2) and go up just like a basic parabola from there. :)

Answer:

q(8) = 39.

Step-by-step explanation:

relate the values

for,

q(x) = 1/2x² + 7

q(8) = 1/2(8²) + 7

q(8) = 39.

Answer:

q(8) = 39

Step-by-step explanation:

To solve this question, you need to plug in (substitute) 8 instead of x:

q(8) = [1/2(8)²] + 7

= (1/2 × 64) + 7

= 32 + 7

= 39

∴ q(8) = 39

Answer:

a) 115°

Step-by-step explanation:

first find the value of angles B and C by doing 180 - 50 =130 and then 130÷2 because B and C are equal

Since the lines BO and CO are bisectors, it means that the angles are halved fo take half of angle B plus half of angle C and add them together = 65 and then do 180-65=115 so the angle BOC is 115°

26) 3 inches

27) We multiply 2 by $3.49 to get the total cost. Or in other words multiply the items by the price to get the total

28) B

29) 1/6

30) 21 degrees was the high temperature

Step-by-step explanation:

- I can't see the clock well, but I'll guess its 10:20. 30 minutes after would be 10:50.

- There are 6 common factors of 50 and 100.

1,2,5,10,50,25

- 12/4 is 3.

- A shopper purchased 2 items, each were $3.49 (That is all the info we need to create an equation to solve/estimate the cost of the purchase) We multiply 2 by $3.49 to get the total cost. Or in other words multiply the items by the price to get the total

- We multiply 1/3 by x amount of batches. So in this case we have 2. It becomes 1/3 times 2 = 1/6

- The low temperature is 8 degrees because each line represents a difference of 2 and 10 - 2 = 8. Now to calculate the high temperature, you add 13 to 8 = 21.

Answer:

D

Step-by-step explanation:

The vertex of the triangle is adjacent to 90° on a straight line, so

vertex = 180° - 90° = 90°

The triangle has 2 congruent sides and is therefore isosceles with 2 congruent base angles, then

x = [tex]\frac{180-90}{2}[/tex] = [tex]\frac{90}{2}[/tex] = 45° → D

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

[tex]\cfrac{7}{9}\:x-\cfrac{4}{9}\:x=\cfrac{1}{4}+\cfrac{5}{12}[/tex]

First, combine  [tex]\frac{7}{9} x[/tex] and [tex]-\frac{4}{9} x[/tex] =  [tex]\frac{1}{3} x[/tex]

[tex]\cfrac{1}{3}\: x=\cfrac{1}{4} +\cfrac{5}{12}[/tex]

LCM of 4 and 12 is 12, Convert 1/4 and 5/12 to fraction with denominator 12:

[tex]\cfrac{1}{3}\: x=\cfrac{3}{12} +\cfrac{5}{12}[/tex]

Since 3/12 and 5/12 have the same denominator, let's add numerators:

[tex]\cfrac{1}{3}\:x=\cfrac{3+5}{12}[/tex]

[tex]\cfrac{1}{3}\:x=\cfrac{8}{12}[/tex]

Reduce the fraction 8/12 to lowest term by extracting and  canceling out 4,

[tex]\cfrac{1}{3} \:x=\cfrac{2}{3}[/tex]

Multiply both sides by 3, reciprocal of 1/3:

[tex]x=\cfrac{2}{3} \times 3[/tex]

Cancel out 3 and 3:

[tex]x=2[/tex]
