Answer:
a) Standard deviation: 3 bluberries
b) We assume, to apply this rule, that the distribution of blueberries per muffin has a bell-curve distribution, approximately normal.
Step-by-step explanation:
We know that the number of blueberries in a blueberry muffin baked by EarthHarvest Bakeries can range from 20 to 40 blueberries.
a) If we use the Empirical Rule 68-95-99.7, specifically the last term, we have that:
- 99.7% of the data will fall between 3 standard deviations from the mean.
Then, if we consider the range of 20 to 40 containing 99.7%, we can calculate the standard deviation as:
Part A.....let x be the amount he earned on Sunday.....so
Amount earned on Saturday + amount earned Sunday =
11 + x =
Represents the total amount he earned
Part B
Let N be the number of dogs that Kyle walked
Then, Larry walked 2N + 4 dogs
Using tan ( opp / adj )
2nd tan = 13 / 6
x = 65.22
to the nearest degree, it would be 65°.
Answer: 24
Step-by-step explanation:
3 divide by 5 equalls 0.6. 0.6 times 40 equalls 24.
