Find what f(x) is when x = -2
3(-2) - 1 = -7
Find g(x) when x = 5
-(5) + 6 = 1
Add -7 + 1
-7 + 1 = -6
Option A)
Answer:
19.2 lbs of dog food in 5 weeks
Step-by-step explanation:
12 divided by 5 is 2.4
So that means each week the dog consumes 2.4 lbs of food each week.
If we want to see how much he eats in 8 weeks, we'd multiply 2.4 by 8, giving us 19.2
Since this is a proportion, we cross multiply.
12/2=9/x (The variable "x" is used the represent the unknown number, and this is the number we are solving for)
12*x=2*9 (Cross multiply)
12x=18 (Simplify)
x=18/12 (Divide each side by 12)
x = 3/2 (Simplify fraction)
The unknown number is 3/2, or 1.5.
Answer:
Claim is false
Step-by-step explanation:
Claim : A credit reporting agency claims that the mean credit card debt in a town is greater than $3500.
n = 20
Since n <30
So we will use t test
Formula : 
s = standard deviation = 391
x = 3600
n = 20
Degree of freedom = n-1 = 20-1 = 19
α=0.10
So, using t table
= 1.72
t critical > t calculated
So we accept the null hypothesis
Hence we reject the claim that the mean credit card debt in a town is greater than $3500.
Answer:
43988ft^3
Step-by-step explanation:
Given data
Radius= 20ft
Height= 35ft
The expression for the volume of a cylinder is given as
Volume= πr^2h
substitute
Volume= 3.142*20^2*35
Volume= 3.142*400*35
Volume= 43988ft^3
Hence the volume is 43988ft^3
