Carmin is trying to find the equation of a line that passes through the points (-1,16) and (5,88) . Does the equation y=12x+28 w
1 answer:
Answer:
Yes! The equation, y = 12x + 28 , work.
Step-by-step explanation:
The line passes through points (-1, 16) and (5, 88)
The slope of the line = change in y ÷ change in x
i.e slope = = 12
Taking another point (x ,y) on the line;
Slope is = 12
y - 16 = 12x + 12
y = 12x + 12 + 16
y = 12x + 28
So the equation, y = 12x + 28, work!

Answer:
The sketch is provided in attached file.
0.0228
Step-by-step explanation:
The sketch is made by taking center at µ=80 and the desired probability of the mentioned area is also demonstrates.
The probability randomly selecting a score greater than 100 from this distribution can be calculated as
P(X>100)=P((X-µ)/σ > (100-80)/10)
P(X>100)=P(z>2)
P(X>100)=P(0<z<∞)-P(0<z<2)
Using normal table the probability corresponds to z-score=2 is 0.0228 and the area on the right side of normal curve is 0.5. So,
P(X>100)=0.5-0.4772=0.0228
The probability randomly selecting a score greater than 100 is 2.28%.
