Step-by-step explanation:
Answer:
B and D
Step-by-step explanation:
Given
x² - x - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)
The factors are - 4 and + 3 , since
- 4 × 3 = - 12 and - 4 + 3 = - 1 , then
x² - x - 12 = (x - 4)(x + 3) ← in factored form
Answer: 0.0222
Step-by-step explanation:
Given : The distribution of trout weights is normally distributed with
Mean : 
Standard deviation : 
Sample size : 
The formula to calculate the z-score is given by :-
Let x be the weight of randomly selected trout.
Then for x = 405.5 , we have
The p-value : 
Thus,the probability that the mean weight for a sample of 40 trout exceeds 405.5 grams= 0.0222.
Answer: 49 cm^2
Step-by-step explanation:
The length of the small pink square box will be:
L^2 = 9
L = sqrt( 9 )
L = 3
The length of the big pink square box will be:
L^2 = 16
L = sqrt( 16 )
L = 4
The length of the yellow square box will be:
4 + 3 = 7
The area of the third square box will be
A = 7^2
A = 49 cm^2
