A.) There are going to be 72 total possibilities. 
Because if you have 6 times 6 is 36 times 2 is 72. 
B.) The probability that the sum on the dice come out to be 11 is 2:72 
Because you can only have (6,5) and (5,6) 
C.) The probability that the sum on the two dice comes out to be 7 is 6:72 
Because you have (6,1) (1,6) (5,2) (2,5) (4,3) (3,4) 
D.) The probability that the numbers on the two dice are equal is 6:72 
<span>Because you have (6,6) (5,5) (4,4) (3,3) (2,2,) (1,1) </span>

Hey You!

We must know what 80% of 500 is:

500 * 80% = 400

Ayden did meet is goal, because his goal was 400 and he painted 415 squares (Which is beyond his goal).

The quadratic model f(x)=-5x^2 +200 represents the approximate height, in meters, of a ball x seconds
katrin [286]

Answer:

x = 5.477 s

Step-by-step explanation:

Your full question can be found in the image below

We can easily solve this question by using a graphing tool or calculator to plot the equation

f(x)=-5x^2 +200

See second attached picture

The ball is 50 meters from the ground when

50 =-5x^2 +200

-150  =-5x^2

x^2 = 30

x = 5.477 s

A biologist is studying the elk population in a county park. She starts with only 2 elk and observes that the number of elk trip
DochEvi [55]

Answer:

The expression that represents the population of elk is: \text{elk}(t) = 2*3^t. It'll take 6 years for the population to reach 1,458 individuals.

Step-by-step explanation:

Since the number of elks triples every year and starts at \text{elk}(0) = 2, then after the first year the population will be:

\text{elk}(1) = \text{elk}(0)*3 = 2*3

While on the second year, it'll be:

\text{elk}(2) = \text{elk}(1)*3 = 2*3*3 = 2*3^2

On the third year:

\text{elk}(3) = \text{elk}(2)*3 = 2*3^2*3 = 2*3^3

And so on, therefore the expression that describes the population of elk as the years passes is:

\text{elk}(t) = 2*3^t

If we want to know the number of years until the population reach 1,458 elk, we need to apply this value to the left side of the equation and solve for t.

1458 = 2*3^t\\3^t = \frac{1458}{2}\\3^t = 729\\ln(3^t) = ln(729)\\t*ln(3) = ln(729)\\t = \frac{ln(729)}{ln(3)} = 6

The population will reach 1,458 elk in 6 years.
