<em /><em>PURPLE MARBLES=P
WHITE MARBLES=W
</em>First, write out an equation showing the number of purple marbles.
P=5W-6
Then, write out the main equation.
W+P=96
W+5W-6=96
Add 6 to both sides.
W+5W=102
6W=102
Divide both sides by 6
W=17
Now that we know there are 17 white marbles, we can go back to the equation about how many purple marbles there are.
P=5W-6
Plug in the value for W, which is 17.
P=5(17)-6
P=85-6
P=79
To make sure your answer is correct, check your work by plugging in the values for P+W=96.
79+17=96
Answer: There are 79 purple marbles.
Answer:
The probability that either Alex or Bryan get an A is 0.9
Step-by-step explanation:
Before we proceed to answer, we shall be making some important notation;
Let A = event of Alex getting an A
Let B = event of Bryan getting an A
From the question, P(A) = 0.9, P(B) = 0.8 and P(A ∩ 
) = 0.1
We are to calculate the probability that either Alex or Bryan get an A which can be represented as P(A ∪ B)
We can use the addition theorem here;
P(A ∪ B) = P(A) + P(B) - P(A ∩ B) .......................(i)
Also,
P(A) = P(A ∩ ) + P(A ∩ B) .........................(ii)
We can insert ii into i and we have;
P(A ∪ B) = P(A ∩ ) + P(A ∩ B) + P(B) - P(A ∩ B) = P(A ∩ ) + P(B) = 0.1 + 0.8 = 0.9
Answer:
d. -18
Step-by-step explanation:
f(-3) = 10x - 3x + 3
10(-3) - 3(-3) + 3
-30 + 9 + 3
-30 + 12
= -18

Answer:
9
Step-by-step explanation:
you can easily solve it by equating the fractions 4/13 and x/91
here, we suppose x as the number of people who can bowl.
4/13=x/91
or, 4/13×91=x (divide 91 by 13)
or, x=4×7
therefore, x=28
easy peesy lemon squeezy ;-)
