Answer:
A
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Here f(x) is shifted 3 units left , then
f(x) → f(x + 3)
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Here f(x) is shifted 4 units down , then
f(x) → f(x) - 4
Thus
f(x) = → f(x) = - 4
The correct interpretation of the standard deviation of the given discrete distribution is:
The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.
<h3>What are the mean and the standard deviation of a discrete distribution?</h3>
- The mean of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
- The standard deviation is the square root of the sum of the difference squared between each outcome and the mean, multiplied by it's respective probabilities.
Hence:
E(X) = 0.4(0) + 0.12(1) + 0.13(2) + 0.15(3) + 0.06(4) + 0.02(5) + 0.02(6) + 0.01(7) = 1.36
Hence the correct option is:
The mean number of days a member worked out would typically be about 1.6764 from the expected number of days.

Step-by-step explanation:
plz see attached file :)✌
To represent this as an equation, you need to show both things that are mentioned in the paragraph. 1. You begin at 600 cm. And 2. The tree grows 3.1 cm per week.
You put both of these together in one equation like this: 600 + 3.1w = h, where w stands for the number of weeks and h stands for the height.
