Answer:
x=4
Step-by-step explanation:
-5(4-x)=-5x+20
We simplify the equation to the form, which is simple to understand
-5(4-x)=-5x+20
Reorder the terms in parentheses
+(-20+5x)=-5x+20
Remove unnecessary parentheses
-20+5x=-5x+20
We move all terms containing x to the left and all other terms to the right.
+5x+5x=+20+20
We simplify left and right side of the equation.
+10x=+40
We divide both sides of the equation by 10 to get x.
x=4
Assuming that all the grapes have the same probability of being randomly picked:
<h3>
How to find the probabilities?</h3>
We know that there are 8 green grapes and 15 red grapes on the bowl, so there is a total of 23 grapes.
a) Here we need to find the probability that both grapes are green. Remember that the probability of getting a green grape is equal to the quotient between the number of green grapes and the total number of grapes, this is:
P = 8/23
But then he must take another, because he already took one, the number of green grapes is 7, and the total number of grapes is 22, so for the second grape the probability is:
P' = 7/22.
The joint probability is the product of the two individual probabilities:
prob = (8/23)*(7/22) = 0.11
b) For the first green grape we know that the probability is:
P = 8/23
Then he must get a red grape. There are 15 red grapes and 22 grapes in total, so the probability is:
P' = 15/22
Then the joint probability is:
prob = (8/23)*(15/22) = 0.24

Answer:
p = 17/48 or 0.354
Step-by-step explanation:
11/16 = p + 4/12
subtract 4/12 from both sides
11/16 - 4/12 = p
convert so you have a common denominator
3(11/16) - 4(4/12)
33/48 - 16/48
= 17/48
p = 0.354
The formula for finding the volume of a cone is V = 1/3 x pi x r^2 x h. Using the information given, you would have the following problem to calculate: 1/3 x 3.14 6 x 6 x 18. The volume is approximately 678.24 cubic cm or 216 pi cm^3. You would give you answer as V = 216 pi cm^3.
