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 annual interest rate on a credit card is 14.99% . If the minimum payment of 40$ is made each month, how many months will it
zmey [24]

Answer:

Let's try and figure it out yearly:

So for the first year the deposits would amount to 40 * 12 = $480

Now since the interest rate is applied yearly we will assume that the interest rate will be applicable to the amount that is left after the first year of deposits

So that would be 889.98 - 480 = 409.98

409.98 * 14.99 % = 61.45

The new amount owed for the second year would be 409.98 + 61.45 = 471.43

So by the end of the second year the debt would of been wiped clean with $8.57 to spare.

So the answer would be 24 months

A system of equations has definitely many solutions. If 2y-4x=6 is one of the equations, which could be the other equation?
NISA [10]

The given equation is ⇒⇒⇒ 2y - 4x = 6

∴ 2y = 4x + 6   ⇒ divide all the equation over 2

∴ y = 2x + 3  and it can be written as ⇒⇒⇒ y - 2x = 3

The last equation represents a straight line with a slope = 2 and y-intercept = 3

To construct a system of equations with definitely many solutions and the equation ( 2y-4x=6 ) is one of the equations, the other equation must have the same slope and the same y-intercept.

so, the general solution of the other equation is ⇒ a ( y - 2x ) = 3a

Where a is constant and belongs to R ( All real numbers )

The system of equations which has definitely many solutions is consisting of <u>Coincident lines.</u>
