(x + 5)(y + 10)
x(y + 10) + 5(y + 10)
x(y) + x(10) + 5(y) + 5(10)
xy + 10x + 5y + 50
Answer:
P(x< 18) = 0.986
Step-by-step explanation:
Step 1: find the z-score using the formula, z = (x - µ)/σ
Where,
x = randomly chosen values = 18
µ = mean = 7
σ = standard deviation = 5
Proportion of the population that is less than 18 = P(x < 18)
Plug in the values into z = (x - µ)/σ, to get z-score.
z = (18 - 7)/5
z = 11/5 = 2.2
Step 2: Find P(x< 18) = P (z<2.2) using z-table.
The probability that corresponds with z-score calculated is 0.986.
Therefore,
P(x< 18) = 0.986
Answer:

Step-by-step explanation:
hello,
let's note x this number we can write

hope this helps
6-(3x+10)+4 (2-x)=15
6-3x-10+8-4x=15
6-10+8-15=4x+3x
7x=-11
x=-11/7
Just do 248.9 + 354.03 (which gets you 602.93). since 600 is below 603.93, patrick is unable to successfully make a 354.03 meter scarf.
