The length of human pregnancies from conception to birth is normally distributed with mean 266 days and standard deviation 16 da

Sidana [21]

Answer:

68 %

Step-by-step explanation:

(a) Using the 68-95-99.7% rule, between what two lengths do the most typical 68% of all pregnancies fall?

95%? 99.7%?

The middle 68% of all pregnancies last between 266-16 and 266+16 days, 250 to 282. The middle 95% of all

pregnancies last between 266-2*16 and 266+2*16 days, 234 to 298 (for future reference, note that this “rule” is

rounded somewhat compared to the charts). The middle 99.7% of all pregnancies last between 266-3*16 and

266+3*16 days, 218 to 314.

Shorty’s Muffler advertises it can install a new muffler in 30 minutes or less. However, the work standards department at corpor

pav-90 [236]

Answer:

The installations at the Maumee branch would you expect to take more than 30 minutes is 10.

Step-by-step explanation:

Consider the provided information.

Let x is the installations at the Maumee branch take more than 30 minutes.

The work standards department at corporate headquarters recently conducted a study and found that 20% of the mufflers were not installed in 30 minutes or less.

Therefore, π=0.20

The Maumee branch installed 50 mufflers last month.

Thus, n=50

Mean of the distribution: μ=nπ

Substitute the respective values in the above formula.

μ=(50)(0.20)

μ=10

Hence, the installations at the Maumee branch would you expect to take more than 30 minutes is 10.

The equation of a line is 5x − 3y = 6. Which is the y-intercept of the line?

oksian1 [2.3K]

Answer:

y - intercept. = 2.

Step-by-step explanation:

Given : The equation of a line is 5x − 3y = 6.

To find : Which is the y-intercept of the line.

Solution : We have given 5x − 3y = 6.

Equation of line y = mx +b

Where , m = slope , y intercept = b

Now we convert the 5x − 3y = 6 in line form y = mx +b

5x − 3y = 6

On subtracting both sides by 5x

-3x = - 5x + 6

On dividing both sides by - 3.

x = $\frac{5x}{3}+2$ .

We cans see m = $\frac{5}{3}$ , y - intercept. = 2.

Therefore, y - intercept. = 2.

Veronica works each day and earns more money per hour the longer she works. Write a function to represent a starting pay of $20

MArishka [77]

<u>Answer:</u>

The range of the amount Veronica makes each hour if she can only work a total of 8 hours is 20 ≤ x ≤ 29.55

<u>Solution: </u>

Let us assume that Veronica worked x hours

The starting pay is $\$20$

Each hour increase is $5\%$

So the function is $f(x)=20(1.05)^{x}$

Now if she works 8 hours, she will earn, $= 20(1.05)^8$

$\Rightarrow 20\times1.477 = 29.55$

So, the range will be 20 ≤ x ≤ 29.55
