The lengths of nails produced in a factory are normally distributed with a mean of 3.34 centimeters and a standard deviation of

Shtirlitz [24]

Answer:

3.47 and 3.21

Step-by-step explanation:

Let us assume the nails length be X

$X \sim N(3.34,0.07^2)$

Value let separated the top 3% is T and for bottom it would be B

$P(X < T)= 0.97$

Now converting, we get

$P(Z < \frac{T-3.34}{0.07})= 0.97$

Based on the normal standard tables, we get

$P(Z < 1.881)= 0.97$

Now compare these two above equations

$\frac{T-3.34}{0.07} = 1.881 \\\\ T = 1.881 \times 0.07 + 3.34 \\\\ = 3.47$

So for top 3% it is 3.47

Now for bottom we applied the same method as shown above

$P(Z < \frac{B-3.34}{0.07})= 0.03$

Based on the normal standard tables, we get

$P(Z < -1.881)= 0.03$

Now compare these two above equations

$\frac{B-3.34}{0.07} = -1.881$

$= -1.881 \times 0.07 + 3.34 \\\\ = 3.21$

hence, for bottom it would be 3.21

A rectangular poster is 50 cm long and 25 cm wide. If 1 cm is approximately .4 inches What is the perimeter of the poster

gulaghasi [49]

It will be 600in or 150cm.
Reason is perimeter is just adding up the sides so if you wanna find it in inches then you multiply 4 by each side and if it’s just cm then just add them all up

What is the inverse of the function f(x) = 4x + 8?

Viktor [21]

Answer: FIRST OPTION.

Step-by-step explanation:

Given the following function:

$f(x)= 4x + 8$

Follow this steps in order to find its inverse:

1. Rewrite the function with $y=f(x)$ :

$y= 4x + 8$

2. Solve for "x":

$y-8= 4x\\\\x=\frac{y-8}{4}\\\\x=\frac{y}{4}-2$

3. Now you must exchange the variables:

$y=\frac{x}{4}-2$

4. And finally, rewrite the function with $h(x)=y$ :

$h(x)=\frac{x}{4}-2$

Therefore, the inverse function is $h(x)=\frac{x}{4}-2$
