Ameena will need a total of 7 packages of paper. (Not every sheet will be used, but having just 6 packages won’t give here enough paper to use). Here’s why:
If she needs 74 copies of the newsletter, and each newsletter contains 8 pages, then she will need a total of 592 pieces of paper (74*8=592). 7 packages will give her 630 pieces of paper to use (90*7=630). 6 packages would only give her 540 pieces of paper (90*6=540), so she needs 7 total packages of paper.
Answer:
0.9821
Step-by-step explanation:
Probability that a randomly selected value will be less than 2.1 deviations from the mean ; this means the Zscore = 2.1
Hence, using :
P(Z < 2.1) = 0.9821 (standard normal table
= 0.9821

Answer:
it is application of the multiplication property of equality
Step-by-step explanation:
You can use "cross products" to solve any proportion. What looks like a "cross product" is just application of the multiplication property of equality. That property says the variable value is unchanged if both sides of the equation are multiplied by the same value.
For your fraction, the "cross product" is what you get when you multiply both sides of the equation by 500.

Note that the next step here is to divide by the x-coefficient, the 5 that was in the left-side denominator.

Please also note that this is exactly the same result you would get by multiplying the original equation by the original denominator of x.
