Answer:

8.625 ft for each side.

Step-by-step explanation:

This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th is 9 (although i doubt saying 1th is right, but just because).

What happens to the value of the expression 150-j as j decrease

astraxan [27]

Answer:

As j decreases, the expression increases.

Step-by-step explanation:

As j decreases, the expression will increase. This is because once it becomes a lower number, it will subtract less from 150, and it will soon eventually add towards with 150, if j is negative.

Hope this helps!

What is the interquartile range of the data?<br><br> I think the answer is B.

zhenek [66]

Answer:

No, correct option is (A) 117.5

Step-by-step explanation:

Interquartile range (IQR) measures the skewness using 50% of the data. It is the difference between the third quartile and the first quartile. i.e.

IQR = Q₃ - Q₁

For finding the Interquartile Range of the data:

100, 120, 130, 188, 196, 220, 265, 300

Divide the data into two parts:

(100, 120, 130, 188) (196, 220, 265, 300)

2. Now finding the medians of both halves of the data that will be our First and Third Quartile of data.

So, Q₁ = 125 and Q₃ = 242.5

Now, using IQR = Q₃ - Q₁

= 242.5 - 125 = 117.5

Hence, Correct option is Option (A).
