Convert first the cost of $98 /yd³ by the conversion factor that 1 yd³ = 27 ft³.
($98 /yd³) (1 yd³ / 27 ft³) = $ 3 17/27/ft³
Let x be the width, the volume of the rectangular portion of the driveway is,
V = (8 ft) (1/3 ft) x = 8x/3 ft³
Using the given total cost of the protion,
C = $58.07 = (8x/3 ft³)(<span>$ 3 17/27/ft³)
x = 5.99957 ft
Thus, the answer is d. 6 feet.</span>
Answer:C
Step-by-step explanation:
Answer:
the answer is c
Step-by-step explanation:
cause math
50(30%) = 15
50 - 15 = 35
35 (6%) = 2.1
35 + 2.1 = $37.10
the total cost of his order is $37.10 !!
Answer:
Conclusion: Fail to Reject Null Hypothesis
We conclude that the bags are not overfilled.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 441 gram
Sample mean, = 448 gram
Sample size, n = 19
Alpha, α = 0.01
Sample standard deviation, s = 27 grams
First, we design the null and the alternate hypothesis
We use One-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject null hypothesis when t > 2.55
We accept the null hypothesis and fail to reject it. Thus, we conclude that the bags are not overfilled.
