Answer:
center = 98.6, variability = 0.08
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation
The center is the mean.
So
The standard deviation of the sample of 50 adults is the variability, so
So the correct answer is:
center = 98.6, variability = 0.08
Answer:
5/8
Step-by-step explanation:
A. 2/3 × 4/5 × m = 1/3 B. 4/5 × 2/3 × m = 1/3
8/15 × m = 1/3 8/ 15 × m = 1/3
m = 1/3 ÷ 8/15 m = 1/3 ÷ 8/15
m = 1/3 ×15/8 m = 1/3 × 15/8
m = 5/8 m = 5/8
C. 2/3 × 4/5 = 1/3 ÷ m
8/15 = 1/3 × 1/m
8/15 = 1/3m cross multiply
(3m) × (8) = 15
24m = 15
m = 15/24
m= 5/8
Answer:
For 14 from left to right should be 11 10 10 9 8 6. For 15 is wrong because 4 people jumped 3 feet and 3 people jumped 4 feet

Answer:
The total fluid you have to drink is 10 7/10 = 10.7 cups.
Step-by-step explanation:
The daily requirement of water = 8 2/4 cups
Now,
or, the daily water requirement = 8.5 cups
The daily requirement of milk = 2 1/5 cups
Now,
or, the daily milk requirement = 2.2 cups
So, The total fluid needed = Cups of (Water + Milk) needed
= 8.5 cups + 2.2 cups
= 10.7 cups
Also,
Hence, the total fluid you have to drink is 10 7/10 cups.
