Consider the following expression and determine which statements are true. x^2+5yz−8

statuscvo [17]

Answer:

A.there are 3 terms.

B.the variables are x, y, and z.

Step-by-step explanation:

Complete question below:

Consider the following expression and determine which statements are true. x^2+5yz−8

CHOOSE 2 ANSWERS)

A.there are 3 terms.

B.the variables are x, y, and z.

C.The coefficient of x is 2.

D.the term 5yz is made up of 2 factors

The expression x^2+5yz-8

has three terms namely: x^2, 5yz and -8

The variables are x, y and z

The coefficient of x is 1 not 2, so option c is wrong

The term 5yz is made up of more than two factors namely 5, y, z, 5y, 5z, 5yz . So option d is also wrong.

The correct answers are option a and option b

A.there are 3 terms.

B.the variables are x, y, and z

What is the means-to-MAD ratio of the two data sets, expressed as a decimal to the nearest tenth?

Romashka [77]

To find the mean of a set, add up all of the data points and divide by the number of data points.
For the first set:
(14+18+21+15+17) ÷ 5 = 85 ÷ 5 = 17
For the second set:
(15+17+22+20+16) ÷ 5 = 90 ÷ 5 = 18

To find the MAD (mean absolute deviation) of a set, find the mean of the distances of each data point from the mean.
For the first set:
(3+1+4+2+0) ÷ 5 = 10 ÷ 5 = 2
For the second set:
(3+1+4+2+2) ÷ 5 = 12 ÷ 5 = 2.4

To find the means-to-MAD ratio of a set, divide its mean by its MAD.
For the first set:
17 ÷ 2 = 8.5
For the second set:
18 ÷ 2.4 = 7.5

Write 0.0007267 in scientific notation.

Lelechka [254]

Answer:

7.267 × 10 (exponent − 4)

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

one number is four more than five times another. If their sum is increased by three, the result is thirty-one

Vadim26 [7]

X is 4 more than 5 times y
x=4+5y

if sum is increased by 3 (x+y+3), result is 31

x+y+3=31
minus 3 both sides
x+y=28
x=4+5y subsiutute
4+5y+y=28
4+6y=28
minus 4 both sides
6y=24
divide by 6
y=4

sub back
x=4+5y
x=4+5(4)
x=4+20
x=24
the numbers are 24 and 4
