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%
9514 1404 393
Answer:
77 in²
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = (1/2)bh
For your triangle, with its base of 14 inches and height of 11 inches, the area is ...
A (1/2)(14 in)(11 in) = 77 in²
_____
<em>Additional comment</em>
The side lengths added to the figure are incorrect. If we take the 11.5 to be correct, then the left side is about 15.3.
You round 92 to 90. Then you round 68 to 70. Now you know that 9x7 = 63. You add to zeros to that answer and get 6300. So 92x68 is about 6300. The actual answer of the problem 6256 that will round up to 6300
