- |Absolute Value| - makes any negative number positive
Step-by-step explanation:
<u>Step 1: Define</u>
-3|5 - s³| + 3t
s = 2
t = 1.5
<u>Step 2: Evaluate</u>
- Substitute in variables: -3|5 - 2³| + 3(1.5)
- |Absolute Value| Exponents: -3|5 - 8| + 3(1.5)
- |Absolute Value| Subtract: -3|-3| + 3(1.5)
- Absolute Value: -3(3) + 3(1.5)
- Multiply: -9 + 4.5
- Add: -4.5
21+21+9+9=
2(9+21)=
Hope this helps
The standard deviation is 19.91.
To find the standard deviation is a binomial distribution, you have to take the square root of the total number multiplied by the percent and its compliment.
Our expression will be:

This will evaluate to about 19.91.
Answer:
C. x = 3cm
Step-by-step explanation:
The formula for volume of a triangular prism is
<u>V = base * height</u>
x in this case equals height, and the base is the area of the triangular base, which is
<u>A(triangle) = 1/2 b*h</u>
= 1/2 7*10 = 35 square centimeters
Plug this back into our formula:
V = base * height
105 = 35x
Solve for x.
105/35 = x
<u>C. x = 3 cm</u>
V = Bh ⇒
h = V/B = 1122 / 93.5 = 12 inches.
