The number of blueberries in a blueberry muffin baked by EarthHarvest Bakeries can range from 19 to 37 blueberries. (a) Use the Empirical Rule to estimate the standard deviation of the number of blueberries in a muffin. (Round your answer to the nearest whole number.) Standard deviation (b) What assumption did you make about the distribution of the number of blueberries

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

idk

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
