Answer with explanation:
Given : The heights of a certain population of corn plants follow a normal distribution with mean 
and standard deviation 
a) Using formula 
, the z-value corresponds to x= 135 will be
At x= 155, 
The probability that plants are between 135 and 155 cm tall :-
Hence, 34.73% of the plants are between 135 and 155 cm tall.
b) Sample size : n= 16
Using formula 
, the z-value corresponds to x= 135 will be
At x= 155, 
The probability that plants are between 135 and 155 cm tall :-
Hence,The percentage of the samples would the sample mean height be between 135 and 155 cm.= 93.12%
Answer:
the answer is 16 i think
Step-by-step explanation:
you need to divide 20 and 1.25 and you will get 16 so the answer is 16
384 would be your answer. Hope this helps!
First, you multiply $7.50 by 0.2 (20%) to get 1.5. Then, you just add 1.5 to 7.5, and your answer is $9.00.
Answer:
3g+57.50=62.90
Step-by-step explanation:
Your total will be 62.90 so its by its self and you need to subtract 57.50 and divide by 62.90
