Answer: 0.7471
Step-by-step explanation:
Given : The Intelligence Quotient (IQ) test scores for adults are normally distributed with a population mean of
and a population standard deviation of
.
Sample size = 50
Using formula
, the z-value corresponding to x=98 will be:-

Z-value corresponding to x=103 will be:-

Using the standard normal distribution table for z-scores, we have
P-value = 
Hence, the probability we could select a sample of 50 adults and find that the mean of this sample is between 98 and 103 = 0.7471
The greatest value would be something like this: What is the value of 3 in 3,829 compared to the value of 3 in 2,693? Choose the number in which 3 has the greatest value.
Answer:
true
Step-by-step explanation:
We have two equations d=55t and d=20g
The left sides of this equations are the same than the right sides are equal too
a) 55t=20g
b) g=(55/20)t
c) t=6h => g=(55/20) *6 = 165/10=16.5 gallons
d= 55t= 55*6=330 miles or d=20g=20*16.5=330 miles
Good luck!!!
Answer:
15.75 > 15.57
Step-by-step explanation:
1. 15.75 is greater than 15.57. ">" means greater than.
2. 15.75 < 15.57 is wrong because 15.75 is not less than 15.57
3. 15.75 does not equal 15.57. They are not equal numbers.
4. This means " 15.75 > 15.57" is correct. Even though they are both 15 the number after the decimals are important to look at too. 75 is greater than 57.
