10. Find which one of the given fractions are value closer to 1.
First = 7/8
Second = 11/10
Let’s start solving
Let us start with the first value which is 7/8
=> 7 needs to be divided with 8
=> 7 / 8 = 0.875
Now, let’s solve the second value which is 11/10
=> same with first solution., divide 11 by 10
=> 11 / 10
=> 1.1
Thus, 11/10 is the has the nearest value to 1.
It will take him 18 minutes b/c it takes him about 1.5 minutes to run 1 mile, therefore 1.5 times 12 is 18 minutes.
A 95% confidence interval on the z-table is 1.96.
Now find the standard error using the formula: standard deviation / square root sample size:
0.7 / √100 = 0.07
Multiply to the confidence interval: 1.96 x 0.07 = 0.137 = 0.14
Now add and subtract tot he average weight:
14 - 0.14 = 13.86
14 + 0.14 = 14.14
The answer is 13.96 ≤ u ≤ 14.14
Answer:
1. (-20/3)+[(2×3+2)/3]=-12/3=4
2. (-5/3)-(2/3)-3= -5-2-6=-3
