The length of the rectangle would be 21

Proportion to set it up would be 7/3 x X/9 cross multiply and solve for x which is 21

$3+\dfrac{x}{2}=10\qquad|\text{subtract 3 from both sides}\\\\\dfrac{x}{2}=7\qquad|\text{multiply both sides by 2}\\\\\boxed{x=14}$

A fair 6-sided die is rolled 10 times (each roll is independent). What is the probability that the rolled die will not show an e

Anestetic [448]

Answer:

1/1024.

Step-by-step explanation:

There are 3 odd numbers in the numbers from 1 to 6. So:

Probability (one toss is odd) = 3/6 = 1/2.

So the Probability ( 10 tosses are all odd) = (1/2)^10

= 1/1024.

Main Idea: To evaluate an exponential growth or decay function, substitute a value for the exponent variable and simplify.

Helen [10]

If there is more to the answer than what I give please ask for more!

With $F(x) = 3^{x}$ we can find $F(4)$ by substituting 4 into the main function.

So it would look like this: $F(4) = 3^{4} = 3*3*3*3 = 81$

Hope this helps!
