D
We know no matter what she will have to spend $35 it’s the fee. So that’s already $35 out of her 100 dollar budget. So she has $65 dollars left to spend on labor cause 100-35 is 65. If it’s 20 dollars per hour we have to find out which answer when multiplied by 20 is the closest to $65 but you can’t go over 2.5 hours x 20 is 50 dollars 2.75 x 20 is 55 3 x20 is 60 and 3.25 x 20 is 65 since 3.25 costs 65 dollars and is the exact about of money Jordan has left and didn’t go over it’s the right answer

A sample with mean of 85 and SD of 12 is transformed into z-scores. After the transformation, what are the values for the mean a
MrRa [10]

Answer:

The value remain unchanged.

Step-by-step explanation:

By Z score, we mean:

Z = \frac{x-\mu}{\sigma}, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,

Z =  \frac{85 - 0}{12} = 85/12 = 7.083333.

NB: We assume that mean and standard deviation are in the same units.

What is 0.2(5x – 0.3) – 0.5(–1.1x + 4.2) simplified? 0.2 [5x + (–0.3)] + (–0.5)(–1.1x + 4.2) x – 2.16
dedylja [7]

0.2(5x – 0.3) – 0.5(–1.1x + 4.2) = 6.5x – 2.06

Solution:

Given expression is 0.2(5x – 0.3) – 0.5(–1.1x + 4.2).

To simplify the expression, first multiply the common term within the bracket.

0.2(5x – 0.3) – 0.5(–1.1x + 4.2)

            = (5x × 0.2 – 0.3 × 0.2)  + (–1.1x × (–0.5) + 4.2 × (–0.5))

            = (1x – 0.06) + (5.5x – 2.1)

            = x – 0.06 + 5.5x – 2

Combine like terms together.

            = x + 5.5x – 0.06 – 2

            = 6.5x – 2.06

0.2(5x – 0.3) – 0.5(–1.1x + 4.2) = 6.5x – 2.06

Hence the simplified form of 0.2(5x – 0.3) – 0.5(–1.1x + 4.2) is 6.5x – 2.06.
