Answer:
32
Step-by-step explanation:
First, combine like terms
4x+7=6x-9
+9 +9
4x+16=-9
-16 -16
Then divide by four to isolate x
4x=-25
x=-6.25
Plug in X to get the angle measure .
Answer:
Step-by-step explanation:
Assuming the number of tickets sales from Mondays is normally distributed. the formula for normal distribution would be applied. It is expressed as
z = (x - u)/s
Where
x = ticket sales from monday
u = mean amount of ticket
s = standard deviation
From the information given,
u = 500 tickets
s = 50 tickets
We want to find the probability that the mean will be greater than 510. It is expressed as
P(x greater than 510) = 1 - P(x lesser than or equal to 510)
For x = 510
z = (510 - 500)/50 = 0.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.9773
P(x greater than 510) = 1 - 0.9773 = 0.0227
Answer:
g < 3
Step-by-step explanation:
in order to stay under his budget of 45 dollars he can get any number of gigabytes less than 3. Its not less than or equal to, because he wants to keep his bill UNDER 45 dollars, and 3 gigabytes plus his plan amounts to 45 dollars exactly.
2 and 9
6 and 9
would be have the least common multiple of 18
Easy
remember
x^-m=1/(x^m)
so
f(-1)=4*7^-1=4*(1/(7^1))=4*(1/7)=4/7
f(2)=4*7^2=4*49=196
