C is parallel to the line.

C or the third one because you have to make the Y by itself and drag the X to the opposite side of the = sign. The x turns to a negative because the sign changes when it switches places. Then when 7y is by itself, you divide everything by 7 so, 7y/7= -3x/7 + 28/7 . You simplify each. 7y/7 cancels down to y. -3x/7 stays the same because it is the slope. 28/7 is 4 because you divide. So you get y= -3x/7 + 4 .

Identify the number of solutions. Y< -1/3x+5, y> -1/3x-1.

Elenna [48]

Answer: C. No solution. ( top shaded. Middle not. Bottom shaded.

Step-by-step explanation:

Given inequalities

y< -1/3x+5 and

y> -1/3x-1.

If we draw graph for y< -1/3x+5 equation, it would be a dotted line and we would shade down the dotted line because we have less than < symbol there.

Now, if we draw graph for second inequality y> -1/3x-1, it would also be a dotted line and we would shade up of dotted line because we have greater than > symbol there.

Now, we can see that slopes of both dotted lines are same that is -1/3.

So, there would not be any common shaded region.

Therefore, there would not by any solution of the system of inequalities.

And correct option is C option.

C. No solution. ( top shaded. Middle not. Bottom shaded.

Item 17 The amount of chlorine in a swimming pool varies directly with the volume of water. The pool has 2.5 milligrams of chlor

zvonat [6]

$8000 gal *\frac{ 1 L}{0.264 gal}*\frac{2.5 mg}{1 L} = 75,757 mg$

Rounding to nearest thousand gives 76,000 mg of chlorine

You have been given data about gas prices in 15 states. Comparing the two data sets below, what does the larger mean and median

Oksanka [162]

Comparing the two data sets shown below

<h3>What is standard deviation and variance?</h3>

Variance is the average squared deviations from the mean, while standard deviation is the square root of this number.

Both the mean and the median can be used to describe where the “center” of a dataset is located.

So, the mean of data in 2022 is more than mean of data in 2018.

It’s best to use the mean when the distribution of the data values is symmetrical and there are no clear outliers.

As the variance of 2022 more than in variance in 2018.

A high variance indicates that the data points are very spread out from the mean, and from one another.

As the standard deviation of 2022 more than in standard deviation in 2018.

The high standard deviation indicates data are more spread out.

The bigger the range, the more spread out the data.
