How you find 8 and 10

Fittoniya [83]

Answer:

8. X = 10.5 and 19. X = 5

Step-by-step explanation:

8. You know that a triangle interior angles should add up to 180° so:

(10x - 11) + (3x - 2) + (3x + 1) = 180

180 = 16x - 12

168 = 16x

The you divide each side by 16:

168 ÷ 16 = 16x ÷ 16

X = 10.5

10. You know that a straight line equals 180° and interior angles add up to 180° so:

1st you do 180 - 151 = 29°

2nd (11x - 1) + (20x - 3) + (29) = 180

180 = 31x + 25

155 = 31x

The you divide each side by 31:

155 ÷ 31 = 31x ÷ 31

X = 5

A student needs to make a square cardboard piece. The cardboard should have a perimeter equal to at least 92 inches. The functio

saveliy_v [14]

Answer: d. s ≥ 23

Step-by-step explanation:

Let s be the side of the square.

We know that the perimeter of a square =4s

Let f(s)=4s

If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like

$4s\geq 92$

Divide both sides by 4, we get

$s\geq\frac{92}{4}\\\Rightarrow\ s\geq23$

Thus, d. is the right answer. The reasonable domain of f(s) is $s\geq23$

The first sequence rule is subtract 8 starting from 72. The second sequence rule is subtract 6 starting from 58. What is the fir

Darya [45]

Answer:

A) 16

Step-by-step explanation:

1st sequence: 72-8x

2nd sequence: 58-6x

Set both sequences equal to each other and solve for x:

72-8x=58-6x

14-8x=-6x

14=2x

7=x

x=7

Plug x=7 back into the equation:

72-8(7)=58-6(7)

72-56=58-42

16=16

So the first number that appears in both sequences is 16.

The variance of the scores on a skill evaluation test is 143,641 with a mean of 1517 points. If 343 tests are sampled, what is t

Vlad1618 [11]

Answer:

The probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216

Step-by-step explanation:

We are given that

The variance of the scores on a skill evaluation test=143,641

Mean=1517 points

n=343

We have to find the probability that the mean of the sample would differ from the population mean by less than 36 points.

Standard deviation, $\sigma=\sqrt{143641}$

$P(|x-\mu|$

$=P(|Z|$

$=0.9216$

Hence, the probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216
