Answer:
15 % are running for a cause.
Step-by-step explanation:
120 out of 800 are running for a cause.
So out of 100, 120 / 8
= 15 are running for a cause.
15 out of a 100 = 15%.
Answer:
C and D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m = 
= 
= 
Using (a, b ) = (9, 3 ) , then
y - 3 = (x - 9) → C
Using (a, b ) = (- 3, - 6 ), then
y - (- 6) = (x - (- 3) ) , that is
y + 6 = (x + 3) → D
Answer:
Step-by-step explanation:
Average speed = total distance / total time taken
Average speed is the total distance traveled divided by the total time taken
The carrier first odometer route is
d_1 = 31,500 miles
On return of the truck, the odometer reads
d_2 = 31,713 miles
The total time taken is 6.5 hours on return
Then,
Average Speed = total distance / total time.
A.V = (d_1 + d_2) / t
A.V = (31,500 + 31713) / 6.5
A.V = 63213 / 6.5
A.V = 9725.1 mile per hour
A.V = 9725.1 mph
If it is continuous that means it covers all values of both y and x meaning your domain is { all real values of x }
Range is { all real values of y}
Answer: the student's score closest to 91 percentile.
Step-by-step explanation:
Since the scores on the standardized test are approximately normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = test scores.
µ = mean score
σ = standard deviation
From the information given,
µ = 480
σ = 90
If a student has a score of 600, then x = 600
For x = 600,
z = (600 - 480)/90 = 1.33
Looking at the normal distribution table, the probability corresponding to the z score is 0.91
the student's score closest to 91 percentile.
