perimeter = 20 +20 +24 = 64 feet

 area = 12^2 + x^2 = 20^2

144 + x^2 = 400

x^2 = 256

x = sqrt(256) = 16 feet

area = 1/2 x 16 x 24 = 192 square feet


 cost = 192 x $2 = $384

Twelve times the quantity of a
Lunna [17]

Answer: x = 13.4

Step-by-step explanation:

We translate 'English' to 'math':

'decreased by' is subtraction

'is' means '='

12(x - 10) = 2x + 14

12x - 120 = 2x + 14

subtract 2x from each side

10x - 120 = 14

Add 120 to each side

     10x = 134

Divide by 10 , to isolate the 'x'

x = 13.4

If we substitute 13.4 for 'x' back in the first equation, we get 40.8 for each side, so the equation balances.

I hope this helps.

2. In two tosses of a fair die, what is the probability that:
zaharov [31]

Answer:

Step-by-step explanation:

The outcomes table is shown in the attached diagram. From the table, the total number of outcomes is 36.

i) the number of outcomes whose sum is 7 are 6 (1,6 2,5 3,4 4,3 5,2 6,1)

The probability that the sum of the two numbers that show up is 7 is

6/36 = 1/6

ii) the number of outcomes whose sum is even are 18

The probability that the sum of the two numbers that show up is even is

18/36 = 1/2

ii) the number of outcomes whose sum is greater than 9 is 6(4,6 5,5 6,4 5,6 6,5 6,6)

The probability that the sum of the two numbers that show up is greater than 9 is

6/36 = 1/6

3) this is a poisson distribution. We want to determine the mean.

Mean = np

p = 5/200 = 0.025

n = 600

Therefore,

Mean = 0.025 × 600 = 15 eggs

15 eggs are expected to be broken from a crate containing 600 eggs
