Perform the indicated operation 5 1/6 - 2 2/3

goldenfox [79]

Answer:

2½

Step-by-step explanation:

First find the Least Common Denominator [LCD], which is 6, then convert 5⅙:

5⅙ → 4 7⁄6

$5 \frac{1}{6} - 2 \frac{2}{3} = 4 \frac{7}{6} - 2 \frac{4}{6} = 2 \frac{3}{6} = 2 \frac{1}{2}$

You see, we regrouped 1 from 5⅙ to make sure that the top mixed number had a higher value than the bottom mixed number, so it is much easier to work with.

I am joyous to assist you anytime.

Can someone please help me with these questions?

A. c+2=c+3
Never. C is a constant value. Adding different values to a constant value will never be equal.

B. 4+2p=4-2p
Sometimes. If p=0 this is true, but not in any other circumstances.

C.2(x+5)+1=2x+11
2x+10+1=2x+11
2x+11=2x+11
Always

A normal distribution is observed from the number of rentals per week for a certain car rental company. If the mean is 15 rental

dexar [7]

The probability that on a randomly selected week, the car company rented greater than 24 rentals is 0.4987

First, we need to calculate the z-score using the formula;

$z=\frac{x-\mu}{\sigma} \\$

where:

$\mu$ is the mean value = 15

$\sigma$ is the standard deviation = 3

x = 24

Substitute the given values into the formula to get the z-score

$z=\frac{24-15}{3} \\z=\frac{9}{3} \\z=3.000$

Checking the probability table for P(x > 3.000), the probability that on a randomly selected week, the car company rented greater than 24 rentals

is 0.4987
