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.

Solve for y.<br> r/3-2/y=s/5
nordsb [41]

Answer:

y = 2 / (r/3 - s/5)

Step-by-step explanation:

r/3 - 2/y = s/5

add 2/y to both sides

r/3 = s/5 + 2/y

Subtract s/5 from both sides

r/3 - s/5 = 2/y

multiply both sides by y

y(r/3 - s/5) = 2

Divide both sides by r/3 - s/5

y = 2 / (r/3 - s/5)

I really need help, I haven't been to school In a while and I kinda forgot what to do. So If anyone is kind enough, please help
marissa [1.9K]

Answer:

P = 20x + 6y + 10

Step-by-step explanation:

The perimeter (P) of the figure is the sum of the sides , that is

P = 2x - y + 3x + 5y + 12 + 6x + 9x + 2y - 2 ← collect like terms

  = 20x + 6y + 10

Given h(t)=-2(t+5)^2+4, find h(-8)
alexandr402 [8]
Substitute -8 for t in  <span>h(t)=-2(t+5)^2+4:

h(-8) = -2(-8+5)^2 + 4    =  -2(-3)^2 + 4    =    -2(9) + 4  = -18 + 4  

h(-8) = -18 + 4 = -14 (answer)</span>

The table shows values for functions f(x) and g(x) .
lozanna [386]

Answer:

-1, 0 and 1

Step-by-step explanation:

Let's work through this step by step.

x goes from -2 to 2 so we will check each integer in between.

f(-2) and g(-2) is the first one.  The table shows f(-2)=-8 and g(-2)=-2, so f(-2) does not equal g(-2)

Now we just keep doing this for x=-1,0,1, and 2

f(-1) = -1 and g(-1) = -1 so f(-1)=g(-1)

f(0)=0 and g(0)=0 so f(0)=g(0)

f(1)=1 and g(1)=1 so f(1)=g(1)

f(2)=8 and g(2)=2 so f(2) does not equal g(2)

So there were three xs that made f(x) = g(x).  -1, 0 and 1, so those are your answers.

if y varies jointly as the square of x and the cube of z and inversely as the square root of w. When x = 2, z = 2, and w = 64, t
LekaFEV [45]

Answer:

40.5

Step-by-step explanation:

if y varies jointly as the square of x and the cube of z and inversely as the square root of w, this is expressed as;

y ∝ x²z³/√w

y = kx²z³/√w

If x = 2, z = 2, y = 12 and w = 64

Substitute;

12 = k (2)²(2)³/√64

12 = 32k/8

12 = 4k

k = 12/4

k = 3

To get y when x = 1, z = 3, and w = 4.

y = 3 (1)²(3)³/√4

y = (3*27)/2

y = 81/2

y = 40.5

Hence the value of y is 40.5
