∗ The volume of that wedge is 1/2BHL

∗ The volume of a rectangular prism is LWH


∗ B = 8
∗ H = 5
∗ L = 11

∗ 1/2 • 8 • 5 • 11 = 220

∗ v = 220cm^3

∗ 2 wedges have a volume of 440cm^3

▪
∗ L = 8
∗ W = 12
∗ H = 5

∗ 8 • 12 • 5 = 480

∗ v = 480cm^3

⋆ The answer is c ⋆

∗ The question says "bikes" which refers to more than 1, and there are 3 people.

∗ It costs $18 a day to rent a bike.

∗ They are renting for 5 days.

∗ Let x represent the number of days.
∗ Let b represent the number of bikes.
∗ Let y represent the total cost.

∗ (b • 18)x = y

∗ (3 • 18)5 = y

∗ 54 • 5 = 270

∗ There are 3 people splitting the cost, so you divide 270 by 3 to get 90.

∗ Each person pays $90

⋆ The answer is D ⋆

To find the expected value of the distribution, we multiply each outcome by it's probability. Doing this, we get that the expected value of defects on a skateboard is of \frac{4}{25}.

Outcomes and probabilities:

0 defects, 9/10 probability

1 defect, 1/20 probability

2 defects, 1/25 probability

3 defects, 1/100 probability.

Expected value:

E(X) = 0\frac{9}{10} + \frac{1}{20} + 2\frac{1}{25} + 3\frac{1}{100} = \frac{1}{20} + \frac{2}{25} + \frac{3}{100} = \frac{5 + 8 + 3}{100} = \frac{16}{100}

Dividing both numerator and denominator by 4:

\frac{4}{25}

Thus, the expected value of defects on a skateboard is of \frac{4}{25}.

HELP PLEASE!!!

Answer:

x^2 + 6

Step-by-step explanation:

X squared or "x^2" just means X times X. For example, 9^2=81 which is the same as 9x9. Then just add 6.

Hope this helps
