Given : y = 8 - 9x

(a) we need to find value of y when x = 2

substituting x = 2 in y = 8 -9x , we get :

y = 8 - 9(2)

y = 8 - 18

y = -10

(b) we need to find value of y when x = 0

substituting x = 0 in y = 8 -9x , we get :

y = 8 - 9(0)

y = 8 - 0

y = 8

John bought a used truck for $4,500. He made an agreement with the dealer to put $1,500 down and make payments of $350 for the n

musickatia [10]

Answer:

(D) 36%

Step-by-step explanation:

Actual cost of truck = $4500

Down payment = $1500

Money left to be paid = 4500-1500 = $3000

A = Monthly payments = 350

n = 10

Principal value (P) = 3000

Using formula,

A= $\frac{Pr(1+r)^{n}}{(1+r)^{n}-1}$

350 = $\frac{3000r(1+r)^{10}}{(1+r)^{10}-1}$

= 36% (approx)

Hence (D) is correct.

Which Mean Absolute Deviation represents more consistency? 15.2 or 10.9

Firdavs [7]

Answer:

10.9

Step-by-step Explanation:

The Mean Absolute Deviation of a given data set tells us how far apart, on average, each data value is to the mean of the data set.

The smaller the Mean Absolute Deviation of a given data set is, the closer each data value is to the mean. This also implies less variability of the data set.

Invariably, the smaller the M.A.D, which connotes less variability, the more consistent the data set is.

Therefore, a M.A.D of 10.9 represents more consistency than a M.A.D of 15.2

Can anyone please help with this?

Yes I can :O

Mean: About 11.87

Median: 11

Mode: 10

Step-by-step explanation:

Mean: Add up all the numbers and divide by the total number of numbers

<em>*deep breath in haha*</em>

6+7+7+8+8+9+9+9+50 (the 10s)+33 (the 11s)+12+12+12+12+13+14+14+16+16+17+17+18+18+19=356

356 (total) / 30 (number of numbers) = 11.8666666666666666666666 etc = 11.87

Median: With all the numbers in order, the middle number (if there are two add them together and divide by 2)

Not much to show, just mark them off starting from the outside getting inside, you end up with 11!

- See attached

Mode: Data value that occurs most often, in this case we can see that 10 happened the most

Hope this helps, have a nice day! :D
