Americans receive an average of 18 Christmas cards each year. Suppose the number of Christmas cards is normally distributed with a standard deviation of 5. Let X be the number of Christmas cards received by a randomly selected American. Round all answers to 4 decimal places where possible. a. What is the distribution of X? X ~ N( , )

b. If an American is randomly chosen, find the probability that this American will receive no more than 21 Christmas cards this year.
(Round z-score up to 2 decimal places.)

c. If an American is randomly chosen, find the probability that this American will receive between 19 and 24 Christmas cards this year.
(Round z-score up to 2 decimal places.)

d. 82% of all Americans receive at most how many Christmas cards? (Please enter a whole number)

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .

idk idk idk idk idk

step-by-step explanation:

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.

1.m=2

2.m=-6

3.m=3

4.m=1/2

glad to
