Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 40 dollars
Standard Deviation, σ = 7 dollars
Sample size,n = 51
We are given that the distribution of cost of shrimp is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P(sample mean would differ by true mean by more than 0.6)
0.5404 is the required probability.
Answer:
x = 84
y = 96
Step-by-step explanation:
Alternate interior angles are a pair of nonadjacent interior angles that are on opposite sides of the transversal. Alternate interior angles are equal.
Therefore, x = y - 12
Angles on a straight line add up to 180°
Therefore, x + y = 180
Substituting x = y - 12 into x + y = 180 and solve for y:
⇒ y - 12 + y = 180
⇒ 2y - 12 = 180
⇒ 2y = 192
⇒ y = 96
Substitute found value for y into x = y - 12 and solve for x:
⇒ x = 96 - 12
⇒ x = 84
Answer:
110
Step-by-step explanation:
30% of her students got an A, divide 33 by 0.3 (30%) to see that 33 is 30% of 110
