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:
Answer:
x=8
Step-by-step explanation:
The exterior angle of the triangle is equal to the sum of the opposite interior angles
11x+2 = 6x+2 + 40
Combine like terms
11x+2 = 6x+42
Subtract 6x from each side
11x+2-6x = 6x+42-6x
5x+2 = 42
Subtract 2 from each side
5x+2-2 = 42-2
5x = 40
Divide each side by 5
5x/5 = 40/5
x = 8
7x-5x=16
2x=16
x=8
so 7*8=56
5*8=40
56:40
56-40=16
H(10) is the altitude of a hot air balloon overtime after 10 minutes. In order to find h(10)'s value, you just have to substitute 10 as t in the equation. h(10) and h(t) represents the value of y in a linear equation. So pretty much: h(10)= 210 - 15(10). If calculated correctly, h(10)=60.
Answer:
First option.
===========================
Step-by-step explanation:
The given set of numbers are:

And it is required to order the set of numbers correctly from least to greatest.
The easiest way is to convert all numbers to decimal and comparing it.

So, The order from least to greatest is as following

So, the correct answer is first option.
