Answer:

z = 50

Step-by-step explanation:

There are 4 numbers in total (5,10,15,z)

The mean is when you get the total of all the numbers and divide by how many there are

If you do the inverse then that means that 20 x 4 = total of all 4 numbers

80 = 15 + 10 + 5 + z

80 = 30 + z

z = 80 - 30

z = 50

You can check you answer at the end

Answer:

12 lbs of $7.80

38 Lbs of $4.30

Step-by-step explanation:

50(5.14)=7.8(x)+4.3(50-x)

257=7.8x+215-4.3x

42=3.5x

12=x, this is how many pounds of $7.80 you need, then subtract 12 from 50 to see how many pounds of $4.30 you need and check your answer

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Answer: $65

Step-by-step explanation: first you want to get rid of the amount in extended warranties, to do this you want to multiply 20 and 18. by doing this you get 360, so subtract 360 from 1530 and you get 1170. To find out the fixed amount per you want to divide by the amount of televisions sold which is 18. So 1170 divided by 18 is 65 so that is the fixed amount.

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

Step-by-step explanation:

Account 1: *Given*

Account 2:

Subtract the new balance from the old balance to represent the change.

\(512 - 432 = 80\)

The bank account had a change of 80.

Account 3:

The change and the old balance are given. Subtract the change from the old balance to represent the new balance.

\(75 - 100 = - 25\)

The new balance is -25.

Account 4:

The change and the new balance are given. Subtract the new balance from the change to represent the old balance.

\(12 - 52 = - 40\)

The old balance is -40.

Account 5: *Given*

Answer:

[A} ( Account 2)  80

[B] ( Account 4)  -25

[C] ( Account 3)  -40

[A] 512-432=80

[B] 75-100= -25

[C] 12-52 = -40

If you got a question that says " Explain what each of the numbers -10,-20, and 0 39 tells you about Account 5." Here the answer below.

Answer: The amount of old account is -10, trading away -20, so the amount of new account is -10-20 = -30

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.
