Store A is cheaper than B
The way to solve is pretty simple for B.
You have to divide the cost by the number of tubes.
So in this case:
9/3=3
15/5=3
21/7=3
See the pattern?
So the cost per lip gloss is $3.
Now for Store A:
Just divide 5.50/2
The answer is 2.75
Compare both numbers
2.75<3.00
So, store A is cheaper.
Answer:
So, the probability is P=0.094.
Step-by-step explanation:
We know that in a recent survey, 73% of the community favored building a police substation in their neighborhood.
We get that p=0.73 and q=1-0.73=0.27.
We calculate the probability that exactly 8 of them favor the building of the police substation, if 14 citizens are chosen.
We get that n=14 and k=8.
We calculate the probability:
So, the probability is P=0.094.

Answer:
The area of the trapezoid is 40 square inches
Step-by-step explanation:
Here, we want to find the area of the given trapezoid
Mathematically, we apply the formula for the area
In this case, a will be 10, b will be 6 and h will be 5
Substituting these values, we have that ;
A = 1/2(10 + 6)5
A = 1/2(16)(5)
A = 40 square inches
Answer:
4n + 3
Step-by-step explanation:
d = (-5) - (-1)
= (-5) + 1
= (-4)
dn + (a - d)
4(n) + [(-1) - (-4)]
4n + [(-1) + 4]
<u>4n + 3</u>
