I have absolutely no idea. sorry that i didn’t answer but thanks for the second answer that i needed to ask my question. i’m stupid do i have no idea what it’s asking. sorry
<span>c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>
So if you distribute 4 in the first parentheses, you get 12x+20y+8z.
Then you distribute 3 in the second parentheses. You'll get 3x-3z. That all equals 12x+20y+8z+3x-3z.
Now you have to start combining numbers with the same variable. Start with x. 12x+3x is 15x.
y has no other common variable, it's left alone.
8z-3z is 5z
All together now with the numbers in simpler form, the equation is 15x+20y+5z
Jenna's would be the right answer because when you distribute 5 in her answer you get 15x+20y+5z
If the ride cost $9 then the miles will be 3 miles.
Step-by-step explanation:
In this question we are given:
Cost of one cab ride R = $3
Additional Cost per mile M = $2
So, Total cost of Cab Ride = $3 + $2M
If cost of cab ride is $9 then we need to find the miles
$3 + $2M = $9
Solving
$2M = $9 - $3
$2M = $6
=> M = $6/$2
M = 3 miles
So, if the ride cost $9 then the miles will be 3 miles.

Answer:
.35lbs or 7/20lbs
Step-by-step explanation:
if 5 1/4 lbs of blueberries are being distributed evenly through 15 cheesecakes, you would divide 5 1/4 by 15 to see how many lbs of blueberries would be in each cheesecake, which would make .35 lbs of blueberries per cheesecake, or 7/20 lbs.
