Answer:
8x4=32 or 8×4
Step-by-step explanation:
it's 32 because you are asking 8 time as many as 4 which is 8x4 or 8x4=3
14*15 is 210 which his the entire area. now divide 210/20 you get 10.5 so you will need at least 11 bags
1.) 3/5 = 0.6
2.) 4/6 = 2/3 = 0.666667
Answer:
a) The 90% confidence interval is
b) The margin of error is 0.063.
Step-by-step explanation:
We have to construct a 90% confidence interval for the proportion of students enrolled in college or a trade school within 12 months of graduating from high school in 2013.
We have a sample of 160 students, and a proportion of:
The standard deviation is:
As the sample size is big enough, we use the z-value as statistic. For a 90% CI, the z-value is z=1.645.
Then, the margin of error is:
Then, the 90% confidence interval is:
