Answer: The probability of rolling 4 in this scenario would be 5/49.

First, lets identify the probabilities of each event. Since, rolling a 1 is twice the probability as the other events, rolling a 1 would be 2/7 and the rest would be 1/7. Adding up these probabilities would give a total of 1 whole.

Second, let find all the possibilities of rolling 4 and add up their probabilities.

P(2, 2) = 1/7 x 1/7 = 1/49
P(1, 3) = 2/7 x 1/7 = 2/49
P(3, 1) = 1/7 x 2/7 = 2/49

Add up those fractions and you will have 5/49.

A population of 200 animals has a growth rate of 1.03% each year. at this growth rate, the function f(x)=200(1.03)^x gives the p
Y_Kistochka [10]
For this case, the first thing we should do is use the following equation:
 f (x) = 200 (1.03) ^ x
 We substitute f (x) = 300:
 300 = 200 (1.03) ^ x
 We clear the value of x:
 log1.03 (300/200) = log1.03 ((1.03) ^ x)
 x = log1.03 (300/200)
 x = 13.72
 Answer: 
 the population will first reach 300 in about 13.72 years.

What’s the answer to X/2+21=36
marshall27 [118]

Answer:

x/2 + 21 = 36

First we get rid of constants to isolate the variable.

In order to do that we must do the inverse operation.

Inverse operation of addition is subtraction.

-21           -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)

x/2 = 15

inverse property of division is multiplication

x2    x2

X = 30
