A factory produces 42,000 computer monitors per day. The manager of the factory claims that fewer than 660 defective computer mo

nitors are produced each day. In a random sample of 240 computer monitors, there are 2 defective computer monitors. Determine whether the manager’s claim is likely to be true. Explain. No, the manager’s claim is not likely to be true. Based on the data, you can predict that there are 665 defective computer monitors produced per day. Yes, the manager’s claim is likely to be true. Based on the data, you can predict that there are 350 defective computer monitors produced per day. Yes, the manager’s claim is likely to be true. Based on the data, you can predict that there are 355 defective computer monitors produced per day. No, the manager’s claim is not likely to be true. Based on the data, you can predict that there are 670 defective computer monitors produced per day.

Answer:

Based on the data, you can predict that there are 350 defective computer monitors produced per day.

Step-by-step explanation:

Given:

Number produced a day, n = 42,000

Defective monitors produced a day = < 600

From a random sample of 240 monitors, only 2 are defective.

For the average number of defective monitors, we have :

240/2 = 120

Which means in every 120 monitors produced, at least one must be defective.

Since 42,000 monitors are produced a day, the number of defective monitors produced a day will be:

42,000 / 120 = 350

350 defective monitors will be produced each day.

Based on the data, you can predict that there are 350 defective computer monitors produced per day.

Normal Distribution Problem. Porphyrin is a pigment in blood protoplasm and other body fluids that is significant in body energy
GarryVolchara [31]

Answer: a) 0.9332, b) 0.8944

Step-by-step explanation: the probability value attached to a z score is gotten by using a z distribution table.

The z score is gotten by making use of the formulae below

Z = x - u / σ

Where x = sample mean, u = population mean and σ = population standard deviation.

a)

For our question, u = 38, σ = 12, we are to look for the z score at z ≤ 56, that's x = 56

By substituting the parameters, we have that

z ≤ 56 = 56 - 38/ 12

z ≤ 56 = 18/12

z ≤ 56 = 1.5

To get the probabilistic value, we check the normal distribution table.

The table I'm using will be giving me probabilistic value towards the left of the area.

From the table, p ( z ≤ 56) = 0.9332.

b)

Z >23 = 23 - 38/ 12

Z >23 = - 15/ 12

Z >23 = - 1.25

The probability value of this z score is towards the right of the distribution but the table I'm using is only giving probability values towards the left.

Hence Z >23 = 1 - Z<23

From the table, Z<23 = 0.1056.

Z >23 = 1 - 0.1056

Z >23 = 0.8944

Decide whether or not each equation represents a proportional relationship. A.The remaining length (L) of 120-inch rope after x
bulgar [2K]

Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:

Equation: y = mx

\frac{y}{x} = m

m is a constant value, which means is the same.

A. Equation: 120 - x = L

Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.

B. Equation: 1.08p = t

Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.

\frac{t}{p}=1.08

C. Equation: x=\frac{m}{4}

This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

\frac{m}{x}=4

D. Equation: V=12s^{2}

This equation is NOT proportional because side length is squared, so it is not constant linearly.

Write the equation of the line f(3)=6 and f(8)=10
LuckyWell [14K]
F(x)=y
so
f(3)=6 and f(8)=10
the points are
(x,y)
(3,6)
(8,10)

y=mx+b
m=slope
b=yintercept

to find the slope between 2 points, (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
(3,6)
(8,10)
slope=(10-6)/(8-3)=4/5

y=4/5x+b
find b


the equation for a line with slope m and a pointn on it is (x1,y1) is
y-y1=m(x-x1)

a point is (3,6)
y-6=4/5(x-3)
y-6=4/5x-12/5
add 6 or 30/5
y=4/5x+18/5
