Answer:
y = 3x + 14
Step-by-step explanation:
Slope: 3
y-intercept: 2 - (3)(-4) = 2 + 12 = 14
The slope is the change in Y over the change in x:
Using the two points shown on the graph:
(1,7) and (0,0)
Slope = (7-0) / (1-0)
Slope = 7/1
Slope = 7
The number if front of the x would be the slope
The answer would be D. y = 7x
z = (x - μ)/σ
Substituting given values, you have
3.6 = (x - 132)/20
(20)(3.6) = x - 132 . . . . multiply by 20
72 + 132 = x . . . . . . . . .add 132
204 = x
The value that has a z-score of 3.6 is 204.
Answer:
3 hours 5 minutes
Step-by-step explanation:
Had he skied 5 minute longer, he would have skied for 4 hours, leaving 3 hours for snowboarding. Since he skied 5 minutes less than 4 hours, he snowboarded 5 minutes more than 3 hours.
You can also just subtract the times.
7 hours - 3 hours 55 minutes =
= 6 hours 60 minutes - 3 hours 55 minutes
= 3 hours 5 minutes
Answer: 3 hours 5 minutes
Answer: 60° is the right answer
