Answer:
$0.04/lb
Step-by-step explanation:
Cost per lb for the 3 lb package is $7.80/(3 lb), or $2.60/lb)
Cost per lb for the 1/2-lb package is $1.28 / [(1/2) lb], or $2.56.
The difference in cost per pound is $2.60 - $2.56, or $0.04/lb
Answer:
D) We are 95 percent confident that the mean difference in scores for all children in the program is between 20.1 points and 23.9 points.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
95 percent confidence interval (20.1,23.9)
We are 95% sure that the population mean(that is, the mean for all children in the program) is in this interval. So the correct answer is given by option D.
It would be: 2/10 * 35 = 7 lbs
so, your answer is 7 lbs
We know, speed = distance / time
s = 1.5/7.5 = 0.2 Km/m
Now, distance = speed * time
Here, t = 1 min.
s = 0.2 Km/m
d = 1 * 0.2 = 0.2 Km
In short, Your Answer would be -2
Hope this helps!
7% of x = 450
0.07×x=450
x=450/0.07
x=6428.6 to the nearest tenth (one decimal place)
