Answer:
Step-by-step explanation:
Given the equation 1/4 (12 x + 8) + 4 = 3, to fnd the result of the equation, the following steps must be followed.
Step 1: Expand the bracket at the left hand side of the equation using the distributive property.
1/4 (12 x + 8) + 4 = 3

Step 2: Subtract 6 from both sides of the equation

Answer:
D
Step-by-step explanation:
Since Alyssa wants to know her gas mileage, which is MILES PER GALLON, she will need to divide total miles by total gallons.
"per gallon" means per 1 unit of gallon, which we will get ONLY IF WE DIVIDE by TOTAL NUMBER OF GALLONS, hence we get "per unit of gallon".
<u>So we need to divide 243.8 miles by 7.71 gallons to get Alyssa's gas mileage.</u>
Answer choice D is right.
Answer:
99% Confidence interval: (0.185,0.375)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 150
Number of cars that have faulty catalytic converters, x = 42
99% Confidence interval:
Putting the values, we get:
The 99% confidence interval for the true proportion of new cars with faulty catalytic converters is (0.185,0.375)
(1,1) because x + 2y <4
=1 + 2(1)
= 3 which is less than 4
