Answer:
You'd need 8 cups of muffin mix to make 12 servings of muffins.
12 x 2/3 = 8 cups of muffin mix
Step-by-step explanation:
Answer: 6 and 7
Step-by-step explanation:
Since, total quantity of hot coca = 
And, when he pours this quantity equal amounts of cocoa into 5 cups.
Then the quantity of hot coca in each cup
= 
= 
Which is between 6 ounces and 7 ounces.
I believe you want to know how much each of them SAVED.
Let the amount saved by Michelle be x, the amount saved by Sam be y and the amount saved by Dean be z.
From the givens:
x = 3y (Michelle saves 3 times as much as Sam).......eq1
y = 2+z (Sam saves 2$ more than Dean)
z=y-2.........eq 2
x+y+z = 240 (total amount)......eq 3
substitute by equation 1 in 3:
3y+y+z=240
4y+z=240......eq 4
substitute by 2 in 4:
4y+y-2=240
5y=242
y= 48.4$
from 1:
x=3y
x=145.2$
from 2:
z=y-2
z=46.4$

Does the given information
describe a probability distribution?
</span>
Yes
<span>
Assuming that a probability
distribution is described, find its mean and standard deviation.
</span>
The mean is equal to 0.6. The standard deviation is equal to 1.5

Use the range rule of thumb to
identify the range of values for usual numbers of bumper stickers.
</span>
<span>The
maximum usual value is 3.5.</span>
<span>max: μ + 2σ = 0.578 + 2(1.462161414) =
3.502322828</span>
<span>The
minimum usual value is 0.</span>
<span>min: μ – 2σ = 0.578 – 2(1.462161414) =
-2.346322828</span>

Is it unusual for a car to have
more than one bumper sticker? Explain.
</span>
No, because the probability of
having more than one bumper sticker is equal to 0.120 that is greater that 0.05
Thousandths (0.007) x hundredths (0.07)
