Answer: 18.25
Step-by-step explanation:
5.5*4=22
401.5/22=18.25
0.75 or 3/4 m each.

100 x 100 is also 100^2 and that equals 10,000
35 x 35 is also 35^2 and that equals 1,225
9 x 9 x 9 is also 9^3 and that equals 729
4 x 4 x 4 x 4 is also 4^4 and that equals 256
2 x 2 x 2 x 2 x 2 is also 2^5 and that equals 32
Let d = number of stamps from John (4 letters, d is 4th letter, etc)
<span>Let e = number of stamps from Johan </span>
<span>Let h = number of stamps from Jonathan </span>
<span>Johan and Jonathan have the same number of stamps, so: </span>
<span>e = h </span>
<span>2 times Johan's collection is 11 less than 5 times John's collection, so: </span>
<span>2e = 5d - 11 </span>
<span>3 times Jonathan's collection is 3 less than 7 times John's collection,so: </span>
<span>3h = 7d - 3 </span>
<span>Now we have three equations and three unknowns. You're asked for the number of stamps in John's collection, so you want the value to variable "d". </span>
<span>Since e = h, we can substitute "h" for "e" in the second equation. </span>
<span>2h = 5d - 11 </span>
<span>3h = 7d - 3 </span>
<span>now we have two equations and two unknowns. I'll use elimination, starting with multiplying the first equation by -3 and the second one by 2. </span>
<span>-6h = -15d + 33 </span>
<span>6h = 14d - 6 </span>
<span>now add both together and you have an equation with one unknown remaining: </span>
<span>0 = -d + 27 </span>
<span>d = 27 </span>
<span>So your answer is 27 stamps. If you want to know how many stamps the others have, you can work back and solve for e and h.</span>

Determine the expected value of grams of sugar
This is calculated by multiplying the probability and grams of sugar in each cereal.
The results of the products are then added together
i.e.
Hence;
The expected value of grams of sugar is 9 grams
