Answer:
x=-4
Step-by-step explanation:
sqrt(x+40) - 17 = -11
Add 17 to each side
sqrt(x+40) - 17+17 = -11+17
sqrt(x+40) = 6
Square each side
(sqrt(x+40) )^2 = 6^2
x+40 = 36
Subtract 40 from each side
x+40-40 = 36-40
x = -4
Answer:
The answer is Option A: "0.2% is a parameter and 11 is a statistic".
Step-by-step explanation:
The main difference between a statistic and a parameter is that a statistic describes a characteristic from a sample and a parameter describes a characteristic of the entire population.
In this case, 11 is the result of the positive salmonella eggs taken out of a sample of 200 eggs. It is a statistic.
Also, we know that of all eggs shipped (the population), 0.2% has salmonella. This 0.2% is a parameter.
The answer is Option A: "0.2% is a parameter and 11 is a statistic".

Answer:
48
Step-by-step explanation:
Given that:
The interval for score = 60 - 42 = 18
If we divide it by the 3 standard deviations; the interval result into
= 18/3
= 6
So, the standard deviation is 6, and the mean = 42 + 6
= 48
