Answer: 8x+12
Step-by-step explanation:
We can use the Distributive Property to get it in it's simplest form
4(2x+3)
(4)(2x)+(4)(3)
8x+12
This would be 4y + 1ytytyty I believe considering they’re all bunched together in the last bit.
Answer:
Step-by-step explanation:
Given that the number of children in a household has a binomial distribution with parameters n-8 and p-50%
As per binomial definition we have

=
a) P(x=3 or 7) = P(3)+P(7) = 0.2188+0.0313=0.2501
b) P(X≤5)=0.8555
c) P(X≥3)=0.8555
d) P(x<7) =0.9648
Answer:
-17
Step-by-step explanation:
3x-7=4x+10
Add 7 to both sides & simplify
3x-7=4x+10
+7 +7
3x=4x+17
Subtract 4x from both sides & simplify
3x=4x+17
-4x -4x
-x=17
*Negative x equals -1*
Divide both sides by -1 & simplify


Answer:
He must sell 8 cards to reach the minimum goal.
Step-by-step explanation:
Giving the following information:
He wants to earn more than $50 at the fair.
He sells his cards for $2 and he has already earned $36.
<u>First, we need to calculate the money required to reach the minimum goal:</u>
51 - 36= $15
<u>Now, we write the inequality:</u>
2*x >15
x= number of cards sold.
x>15/2
x> 7.5
He must sell 8 cards to reach the minimum goal.
