Answer:
17
Step-by-step explanation:
since it is in the middle you can just divide by 3 since one will be greater and one will be less so 51/3=17
Expand
x^2+3x-10=18
minus 18 both sides
x^2+3x-28=0
find what 2 numbers mutiply to -28 and add to 3
7 and -3
(x+7)(x-3)=0
set each to zero
x+7=0
x=-7
x-3=0
x=3
x=-7 and 3
Answer:
0.2196
Step-by-step explanation:
Given that
Mean = 4.56 million visitors per day
Standard deviation = 820,000 visitors per day
According to the given situation the calculation of probability is shown below:-
Here we will find the value of P (3 ≤ X ≤ 4)



= 0.2483 - 0.0287
= 0.2196
Therefore the probability that the web site has between 3 million and 4 million visitors in a single day is 0.2196
you know 1 gallon is 16 cups.
1/2 a gallon will be 8 cups.
So, its asking how much is 1 1/2 gallon to cups. Add 16+8= 24.
24 is the answer
