For one part of the study, n = 114 male athletes from eight Canadian sports centers were surveyed. Their average caloric intake
Lady_Fox [76]

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.

Z=(3421,7-3077)/987=0,35

As you can see at the attachment %63,7 of athletes are taking less than 3421.7 Calories.

114*63,7/100=73

Approximately 73 athletes are taking less than 3421.7 Calories.

A line is drawn through (-7,11) and (8,-9). The equation y - 11 = -4/3(x+7) is written to represent a line. Which equations also
Ad libitum [116K]

Answer:

4x + 3y = 5

Step-by-step explanation:

Given

y - 11 = - \frac{4}{3}(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
