Ilya [14]2 years ago
5 0

Answer:

66

Step-by-step explanation:

84 = mean + 3sd

60 = mean - sd

sd = mean - 60

84 = mean + 3(mean - 60)

84 = mean + 3mean - 180

264 = 4mean

mean = 66

A 22inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third pie
Dovator [93]

Answer:

<h2>The length of the pieces is 3 inch, 6 inch and 13 inch.</h2>

Step-by-step explanation:

Let, the length of the first piece is x inch.

Hence, the length of the second piece is 2x.

It is given that, the length of the third piece is one inch more than four times of the first piece. Hence, the length of the third piece is 4x + 1 inch.

The total length of the steel is 22 inch.

Hence, x + 2x + 4x + 1 = 22

or, 7x = 21

or, x = 3.

The length of the second piece is 2x = 2\times3 = 6 inch.

The length of the third piece is 4x + 1 = 12 + 1 = 13 inch.

Solve 1/11c &gt; 9. Graph the solution. . The solution is​
Katarina [22]

Answer:

I suppose that the inequality is:

(1/11)*c > 9.

To solve this we need to isolate c in one side of the inequality.

To isolate it, we need to multiply both sides by 11, then we get:

11*(1/11)*c > 9*11

c > 9*11 = 99

c > 99.

To graph this, we will have an open dot at c = 99, and an arrow that points to the right direction.

The graph is shown below.
