Annabel is comparing the distances that two electric cars can travel after the battery is fully charged. Car A (miles) Car B (mi

Maslowich

Answer:

Car B can travel further than Car A after the battery is fully charged.

D. Car B because the measures of variability are smaller for Car B than for Car A.

Step-by-step explanation:

Car B can travel further than Car A after the battery is fully charged because Car A has lesser mean and median than Car B.

Median divides the data into two halves. A smaller median means that there is lesser mileage of Car A than Car B.

There are two measures.

Measure of center tells us how much near or far the data is spread from the center.

The mean , median and mode are the measures of center.

Car A has less mean , median telling us that it traveled less.

Measure of Variability tells us how data changes with a single value.

Smaller MAD means the data is denser at the mean. Car B has lesser MAD.

Smaller IQR tells us that data is closer to the middle of the data.

Car B has smaller IQR .

So car B traveled consistently as it has smaller IQR and MAD

D. Car B because the measures of variability are smaller for Car B than for Car A.

The slope of the line is - 2<br> O True<br> O False

aniked [119]

Answer:

<h2><u>FALSE</u></h2>

Step-by-step explanation:

To find the slope you need to pick two points. Points (2,4) and (4,3) are the points I used. (It does not really matter what points you chose). Now we have to follow the formula to find the slope. The formula can be seen below

Slope (m) = ΔY/ΔX

Now solve

ΔX = 4 – 2 = 2

ΔY = 3 – 4 = -1

Once you have solved it, you take it and make it a fraction

-1/2 = -0.5

If r = x, y, z and r0 = x0, y0, z0 , describe the set of all points (x, y, z) such that |r − r0| = 5.

Artist 52 [7]

We are concern about the vector (x-x0, y-y0, z-z0) equaling to 5.

This happens when √(x-x0)^2 + (y-y0)^2 + (z-z0)^2 = 5

Square both side:

(x-x0)^2 + (y-y0)^2 + (z-z0)^2 = 25 , a sphere

Which you will recognize as a circle of radius one centered at (x0, y0, z0)

3. Theresa has 20 coins that are dimes and quarters. Together

KiRa [710]

Answer:

15 dimes
5 quarters

Step-by-step explanation:

Let q represent the number of quarters Theresa has. Then the value of her coins is ...

0.25q + 0.10(20 -q) = 2.75

0.15q = 0.75 . . . . . . . . . subtract 2.00, collect terms

q = 0.75/0.15 = 5

Theresa has 5 quarters and 15 dimes.

Please help me out and show work

lina2011 [118]

Answer:

$s(x)=\frac{0.2}{x+5}$

Step-by-step explanation:

In 5 liters, there is 4% salt.

Lets find liters of salt.

First, converting 4% to decimal (dividing by 100):

4% = 4/100 = 0.04

0.04 * 5 = 0.2

So, there is 0.2 liters of salt.

Now, x liters of water is added to total, so total is now:

5 + x

The concentration of salt will be amount of salt divided by amount of salt water solution.

Amount of salt = 0.2 (as seen above)

Amount of new salt water solution = x + 5

So,

Concentration of salt in new solution is $\frac{0.2}{x+5}$

2nd choice is right.
