Compute 95% confidence intervals for the proportion of defective items in a process when it is found that a sample of size 100 yields 8 defectives.
Answer:
0.02683<x<0.133173
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = p ± z√p(1-p)/n
p is the proportion
z is the confidence interval at 95% confidence
n is the sample size
Since it is found that a sample of size 100 yields 8 defectives, the sample proportion p = 8/100 = 0.08
Given
n = 100
z score = 1.96
p = 0.08
1-p = 1-0.08 = 0.92
Required
95% confidence interval
Substitute the given parameters into the formula as shown;
CI = p ± z√p(1-p)/n
CI = 0.08 ± 1.96√0.08(0.92)/100
CI = 0.08 ± 1.96√0.0736/100
CI = 0.08 ± 1.96(0.027129)
CI = 0.08 ± 0.053173
CI = (0.08-0.053173, 0.08+0.053173)
CI = (0.02683, 0.133173)
Hence the 95% confidence intervals for the proportion of defective items is 0.02683<x<0.133173
Mrs adam walk between 4\10 and 6\10 mile every day. which is the best estimate of the number of miles she walks in 30 day
5/10 is between 4/10 and 6/10, so you could say they average 5/10 miles per day.
5/10 = 1/2
1/2 mile per day x 30 days = 15 miles
The best estimate is she walks 15 miles in 30 days.

4x – 3y = 11
8x + 2y = 46
Answer:
y=-17 x=10
Step-by-step explanation:
4x-3y=11
8x+2y=46
8x-6y-22 8x+2(-17)=46
8x+2y=46 8x-34=46
2y-6y 46-(-22) 8x=80
-4y=68
y=-17 x=10
The load that can be supported by a rectangular beam varies jointly as the width of the beam and the square of itsâ height, and inversely as the length of the beam. A beam feetâ long, with a width of inches and a height of inches can support a maximum load of pounds. If a similar board has a width of inches and a height of âinches, how long must it be to support âpounds?
The question is incomplete.Here is the complete question.
The load that can be supported by a rectangular beam varies jointly as the width of the beam and the square of its length, and inversely as the length of the beam. A beam 13 feet long, with a width of 6 inches and a height of 4 inches can support a maximum load of 800 pounds. If a similar board has a width of 8 inches and a height of 7 inches, how long must it be to support 1300 pounds?
Answer: It must be 392 inches or approximately 33 feet.
Step-by-step explanation: According to the question, the measures (width, length and height) of a beam and the weight it supports are in a relation of proportionality, i.e., if divided, the result is a constant.
For the first load:
width = 6in
height = 4in
length = 13ft or 156in
weight = 800lbs
Then, constant will be:
[tex]\frac{6.4^{2}}{156} k = 800[/tex]
[tex]k=\frac{800.156}{96}[/tex]
k = 1300
For the similar beam:
[tex]\frac{8.7^{2}}{L}1300=1300[/tex]
L = 49.8
L = 392in or 32.8ft
A similar board will support 1300lbs if it has 392 inches or 32.8 feet long.

For which equations is 8 a solution? Select the four correct answer
Answer:
I believe the answers are= 2, 3, 6, 8
Step-by-step explanation:
For #2, you would subtract 2 from both sides. 10-2=8. x=8.
For #3, you would add 4 to both sides of the equation, making the final answer: x=8
For #6, you would divide both sides by 3. 24 divided by three is 8.
For #8, I multiplied the whole equation by 8, which is the denominator of x/8. 1 times 8=8. The final answer would be x=8.
Hope this helps!
The equations whose solution is 8 will be x + 2 = 10, x - 4 = 4, 3x = 24, and x/8 = 1. Then the correct options are B, C, F, and H.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Let's check all the options. Then we have
A. x + 6 = 2, simplify the equation, then we have
x + 6 = 2
x = - 4
B. x + 2 = 10, simplify the equation, then we have
x + 2 = 10
x = 8
C. x - 4 = 4, simplify the equation, then we have
x - 4 = 4
x = 8
D. x - 2 = 10, simplify the equation, then we have
x - 2 = 10
x = 12
E. 2x = 4, simplify the equation, then we have
2x = 4
x = 2
F. 3x = 24, simplify the equation, then we have
3x = 24
x = 8
G. x/2 = 16, simplify the equation, then we have
x / 2 = 16
x = 32
H. x/8 = 1, simplify the equation, then we have
x/8 = 1
x = 8
The equations whose solution is 8 will be x + 2 = 10, x - 4 = 4, 3x = 24, and x/8 = 1. Then the correct options are B, C, F, and H.

There are 6 numbers on a standard number cube. If the rolling is random, there should be a 1/6 chance of rolling a certain number. Basically, someone would theoretically roll each number 100 times out of 600. Because there are two numbers on the dice greater than 4, multiply 100 by 2 to find the answer.
