Answer:
250%
Step-by-step explanation:
To find the percent increase, divide the end amount by the primary amount:
45 ÷ 18 = 2.5
Now simply multiply this value by 100:
2.5 x 100 = 250
So the percent increase is 250%!

Answer with Step-by-step explanation:
We are given that an equivalence relation P on Z as
Let 
if and only if 
such that x-y=2k.
We have to show that how the reflexive property and symmetric property of an equivalence relations hold for P on Z.
We know that reflexive property
a is related to a by given relations.
If xPax then we get
Where k=0 and 0 belongs to integers.
Hence, the relation satisfied reflexive property.
Symmetric property :If a is related to b then b is related to b.
If x and y is related by the relation
where k is any integer
k belongs to integers.
Hence, relation satisfied symmetric property.

Answer: 0.3
Step-by-step explanation:
From the question,
A used car dealer sells SUVs and cars. Of all the vehicles, 70% are cars. Since 70% are cars, SUV will be (100% - 70%) = 30%. Of all the vehicles, 10% are black SUVs. To calculate the probability than an SUV chosen is black goes thus:
P(A|B) = P(A and B) / P(B)
P(SUV | black) = P(SUV and black) / P(suv)
P(suv | black) = 10%/ 30%
P(suv | black) = 0.1/0.3
P(suv | black) = 0.3
