Answer: A. $0.60
Step-by-step explanation:
The prices for which the carpets were sold are
1) 100 square feet for $67
2) 200 square feet for $130
3) 400 square feet for $240
4) 800 square feet for $504. We would determine the unit cost per square foot for each of them. It becomes
1) 1 square feet costs 67/100 = $0.67
2) 1 square feet costs 130/200 = $0.65
3) 1 square feet costs 240/400 = $0.6
4) 1 square feet costs 504/800 = $0.63
The unit cost per square foot of carpet for the worst deal is $0.6
Answer: 
Step-by-step explanation:
Group like terms:
Simplify the arithmetic:
Add 7 to both sides:
Simplify the arithmetic:
Simplify the arithmetic:
Divide both sides by 3:
Simplify the fraction:
Find the greatest common factor of the numerator and denominator:
Factor out and cancel the greatest common factor and the answer will be:
4 2/3 into improper fracking would be 14/3 now times 3 , 3 and 3 go into 1 so your left with 24 so THATS the answer in other words it would be 42/3 which goes into 14 times:)
Answer:
Test statistic = 1.664
Step-by-step explanation:
The hypothesis :
H0 : μ = 47.2
H1 : μ ≠ 47.2
Given that :
Sample mean, xbar = 47
Sample size, n = 250
Standard deviation, σ = 1.9
The test statistic :
(xbar - μ) ÷ (σ/√(n))
T = (47 - 47.2) ÷ (1.9/√(250))
T = (0.2 / 0.1201665)
Test statistic = 1.664
