Answer:
μ−2σ = 1,089.26
μ+2σ = 1,097.62
Step-by-step explanation:
The standard deviation of a sample of size 'n' and proportion 'p' is:
If n=1139 and p =0.96, the standard deviation is:
The minimum and maximum usual values are:
Answer:
B
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
= -
Given m = - , then
= - =
Since m > 0 then lines LM and No are the 2 possible lines
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = L(- 5, - 3) and (x₂, y₂ ) = M(0, 3)
m = =
Hence the required line is LM

if it doubles every four hours and you are finding it by 12, times the answer by 2 three times.
Answer:
The random variable is continuous. The possible values are a greater than 0.
Step-by-step explanation:
We have to identify if "Square Footage of a house" is a discrete variable or a random variable. For this first we need to understand the difference between both type of variables.
Discrete Variable:
A discrete variable can only take specific value e.g. number of people in a hotel which can take only whole number values like 15, 43, 155 etc. A discrete variable is counted. Examples are: Number of people, number of books etc
Continuous Variable:
A continuous variable can take all the values within its specific range. For example, weight of a person. Weight can take any value greater than 0. Weight can be in decimals, can be in integers. A continuous variable is always measured.
The given variable: "Square Footage of a house" can take any value greater than 0, there is no limit to it. "Square Footage of a house" is always measured.
Based on this we can conclude that "Square Footage of a house" is a Continuous variable and can take all values greater than 0.
the missing number should be the square root of the last number times 2 for a perfect trinomial
so square root of 49 = 7
7*2 =14
so the missing number should be 14
