mixer [17]

Answer:

Slope = 7.2 g/mL

Step-by-step explanation:

Density = mass/volume

Density is also the slope of the relationship between mass and volume.

When a graph between mass and volume is plotted, its slope gives the density of the object.

If the density is 7.2 g/mL, it would mean that the slope is 7.2 g/mL. Hence, this is the required solution.

At a costumer service call center for a large company, the number of calls received per hour is normally distributed with a mean
Marysya12 [62]

We have been given that at a customer service call center for a large company, the number of calls received per hour is normally distributed with a mean of 150 calls and a standard deviation of 5 calls. We are asked to find the probability that during a given hour of the day there will be between 146 calls and 163 calls.

First of all, we will use z-score formula to find z-score corresponding to 146 and 163.

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

z=\frac{146-150}{5}

z=\frac{-4}{5}

z=-0.8

z=\frac{163-150}{5}

z=\frac{13}{5}

z=2.6

Our next step is to find percentage of data scores falls between both z-scores.

P(-0.8

Using normal distribution table, we will get:

P(-0.8

P(-0.8

Let us convert our answer into percentage.

0.78348\times 100\%=78.348\%

Upon rounding our answer to nearest thousandths, we will get:

78.348\%\approx 78.35\%

Therefore, the probability that during a given hour of the day there will be between 146 calls and 163 calls is approximately 78.35\%.

How do I solve -2y = 34 ??
weeeeeb [17]

Answer:

<u>y= -17</u>

Step-by-step explanation:

In order to solve for y you need to get y by itself on one side of the equation.

This is very simple and all you need to do is divide each side by -2.

-2y=34

/-2        /-2

<u>y= -17</u>

34 divided by -2 is -17
