Is "None" an option? All of these answers are wrong.

The number is greater than 2. - 2 is not less than 2.
The number is not divisible by 5. - 2,3,4 are not divisible by 5.
The number is even or less than 12. - 3 is not even.

The number is neuther (assuming neither) prime nor composite. - 4 is not prime. But all numbers are either prime or composite, so was this typed incorrect?

<span>The square root of the number is less than 3 - Root of 10 is 3.16</span>

Answer:

3.9

Step-by-step explanation:

Given the data:

Payout ($) (x) : 0 2 4 8 10

Probability p(x) : 0.35 0.2 0.1 0.2 0.15

The expected winning ; E(X) = Σ(x * p(x))

Σ(x * p(x)) = (0*0.35)+(2*0.2)+(4*0.1)+(8*0.2)+(10*0.15)

= 0 + 0.4 + 0.4 + 1.6 + 1.5

= 3.9

Turning off the water while brushing your saves 379 centimetres of water .How many litres of water can you save if you turn off
Scrat [10]
First you need to find out how many cm of water that will be saved after brushing your teeth 3 times.

379 x 3 = 1137

Next you need the convert the cm to liters. You do this by dividing the cm total by 1000.

1137 / 1000 = 1.137

So you would save 1.137 liters of water while brushing your teeth 3 times.

Hope this helps!!

Let A = Aaron's age today and M = Maria's age today.
kondor19780726 [428]

Aaron is 4 years and Maria is 14 years old.

A = Aaron's age today

M = Maria's age today.

a. The equation based on the statement given will be:

M = A + 10

b. Maria's age based on the statement in 6 years will be:

= (A + 10) + 6

= A + 16

c. Based on the information above, the equation to solve their ages will be:

A + 16 = 2(A + 6)

A + 16 = 2A + 12

Collect like terms

2A - A = 16 - 12

A = 4

Therefore, Aaron is 4 and Maria is 14 years.
