Answer:
(2,0)
Step-by-step explanation:
2x-y=4 equation 1
3x+y=6 equation 2
5x=10 eliminate y by adding equations
x=2
solve for y
2x-y=4
2(2)-y=4
4-y=4
-y=0
y=0
check answer:
3x+y=6
3(2)+0=6
6=6
Answer:
D
Step-by-step explanation:
An isosceles triangle is a triangle that has two sides of equal length.

Answer: 0.62%
Step-by-step explanation:
Given : The number of calories in peanut M&Ms have an approximately normal distribution with
Standard deviation :
Let x be the amount of calories in a randomly selected peanut M&Ms.
Z-score :
The probability that the peanut M&Ms are more than 15 calories using standardized normal distribution table :
In percent ,
Hence, the percentage of peanut M&Ms are more than 15 calories is 0.62%.
