Answer:
Yes there is evidence that Canadian high-performance male athletes are deficient in their caloric intake
Step-by-step explanation:
Expected value of one Canadian Player caloric intake is 3077 calories. Standard deviation of those players are 987. Lets consider that they fits in Gaussian distribution model. We need to find Z value to find the percentage of athletes that take more than 3421,7 calories.
As you can see at the attachment %63,7 of athletes are taking less than 3421.7 Calories.

Approximately 73 athletes are taking less than 3421.7 Calories.
Answer:
4x + 3y = 5
Step-by-step explanation:
Given
y - 11 = -
(x + 7)
Multiply through by 3
3y - 33 = - 4(x + 7) ← distribute
3y - 33 = - 4x - 28 ( add 4x to both sides )
4x + 3y - 33 = - 28 ( add 33 to both sides )
4x + 3y = 5
8.8-3.4=5.4
Just subtract 8-3 and 8-4 and you'll get 5.4
Hope it helps!

Brainliest please if you found my answer helpful! :)
It would be 4
5 - (- 1)
Would just be 5 - 1 which is 4
