Answer:

x = 10 ft, or each story is 10 ft tall

Step-by-step explanation:

We know that the house is 26 ft tall. We also know that the attic is 6 ft tall. We also know that there are two stories, and that they are the same height as one another (since each story is x tall). In math form, this is:

6 + x + x = 26

Combine like terms

6 + 2x = 26

Subtract 6 from each side

2x = 20

Divide each side by 2

x = 10

Our final answer^^

Brainliest please maybe??

Is x = 9 in the solution set of the inequality x + 14 < 20 Yes or no

notsponge [240]

Answer: No

Step-by-step explanation:

Data: x+14<20

x=9? Is what your trying to find

Step one, Isolate x by subtracting 14 on both sides

X+14-14<20-14=X=6

Reason: Since you are trying to find if x=9, you have to isolate it. The way to do that is to get rid of +14 by subtracting it by 14. However, since what you do to one side you do to the other, you subtract +20 by 14 to get 6.

Since x=6 isn't x=9, the answer is No

Answer: No

Systematic Sampling Technique is used to select 5 numbers between 1 and 200. The first selected number is 12. What should be nex

Zina [86]

Answer: 52, 92 , 132, 172

Step-by-step explanation:

A systematic random sampling is a random sampling technique in which a sample from a large population are chosen according to a random beginning point and a fixed periodic interval (k).

Given : Systematic Sampling Technique is used to select 5 numbers between 1 and 200.

⇒ Population size : N=200

Required Sample size : n=5

Since , Sampling interval is given by :-

$k=\dfrac{N}{n}$

⇒ [tex]k=\dfrac{200}{5}[=40/tex]

If the first selected number is 12, then the next four numbers would be :

(12+K) , (12+2k) , (12+3k) , (12+4k)

Put value of k , we get

(12+40) , (12+2(40)) , (12+3(40)) , (12+4(40)) =(52, 92 , 132, 172)

Hence, the next four numbers are : 52, 92 , 132, 172
