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:
factors are x-3 and x+2
Step-by-step explanation:
If the zeros of the functions are x = 3 and x = -2, hence the factors in terms of x are (x-3) and (x+2)
Get the function
(x-3)(x+2)
= x^2+2x-3x-6
= x^2 - x - 6
Hence the required function is x^2 - x - 6 and the factors are x-3 and x+2
Answer:
yes we need to as it helps with math stuff later on
Step-by-step explanation:
Answer:
9.4606 × 10^12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Required
Write the equivalent cosine function
The general formula is:
Where
Substitute 
for amplitude in
Substitute 3 for period in
<em>Multiply both sides by b</em>
<em>Divide through by 3</em>
Hence;
becomes
