The reputation of many businesses can be severely damaged due to a large number of defective items during shipment. suppose 300 batteries are randomly selected from a large shipment; each is tested and 9 defective batteries are found. at a 0.1 level of significance, does this provide evidence that the proportion of defective batteries is less than 5%? what is the p-value for the test.

Answers

Answer 1

Answer: We are given with
random samples = 300 batteries
defective samples = 9 batteries
level of significance = 0.1
Using the P-table values and using the given values, we see that the number of defective batteries are really less than 5%

What is the simplified form of (radical) 400x^100 ?200^10
200^50
20^10
20^50

Answers

$\sqrt{400x^(100)}=\sqrt{(20x^(50))^(2)}\n\n=20x^(50)$

We suppose you intend this to match the 4th selection.

Answer: The simplified form of the radical is $20x^(50).$

Step-by-step explanation: We are given to find the simplified form of the following radical:

$R=\sqrt{400x^(100)}.$

We will be using the following square root property:

$√(a)=a^{(1)/(2)}.$

The simplification is as follows:

$R\n\n=\sqrt{400x^(100)}\n\n=(400x^(100))^(1)/(2)\n\n=(20^2x^(100))^(1)/(2)\n\n=20^{2*(1)/(2)}* x^{100*(1)/(2)}\n\n=20* x^(50)\n\n=20x^(50).$

Thus, the simplified form of the radical is $20x^(50).$

The hypotenuse of one side of a right angled triangle are 5cm and 4cm respectively. what is the length of the other side

Answers

Answer: 3cm

Explanation:

We can use Pythagorean’s theorem to find that other side:

a^2 + b^2 = c^2
a^2 + 4^2 = 5^2
a^2 = 25 - 16
a^2 = 9
a = 3

Therefore, the other side is 3cm

Answer:

Hypotenuse is the longest side in a triangle.

a^2=b^2+c^2.

5^2=4^2+c^2.

c^2=25-16.

c^2=9.

c=√9.

c=3cm.

Write an equation for the description . The length of a rectangle is twice its width . The perimeter of the rectangle is 122 feet.

Answers

Answer:

122 = 2(2w +w)

Step-by-step explanation:

If we let w represent the width of the rectangle, then 2w is the length of it. The perimeter is twice the sum of length and width.

P = 2(L+W)

122 = 2(2w +w) . . . . an equation for the description

An automobile manufacturer would like to know what proportion of its customers are dissatisfied with the service received from their local dealer. The customer relations department will survey a random sample of customers and compute a 95% confidence interval for the proportion that are dissatisfied. From past studies, they believe that this proportion will be about 0.28. Find the sample size needed if the margin of error of the confidence interval is to be no more than 0.02.
