Answer:
the forth point
Step-by-step explanation:
first locate 4x2= 8 go to 8 then half it 8/2 and go down to the 4th point and voila
Answer:
a) 0.2347, 0.0007
b) 1.30
c) 0.63
Step-by-step explanation:
Given –
Mean = 73.4
Sigma = 4.7
Probability that the speed is greater than 70 is
P (X>70) = P (z> (70-73.4)/4.7) = P (z>-0.72) = 0.7653
a) The probability that a car is not speeding = 1 - 0.7653 = 0.2347
The probability that all 5 cars are not speeding = (0.2347)5 = 0.0007
b) E (X) = 1/p = 1/0.7653 = 1.30
c) Standard deviation = Sqrt (1-p/p) = (1-0.7653)/0.7653 = 0.63
Hello!
The equation, y = mx + b is slope-intercept form. In this equation, m is the slope, and b is the y-intercept.
If the baby was exactly 8 pounds when it was born, then the y-intercept is (0, 8) because at zero months, the baby was eight pounds. To find the rate of change, we can use the the y-intercept (0, 8), and the weight of the baby at four months, which is (4, 8 + 3) → (4, 11).
Since we have two points, we can use the slope formula 
to find the rate of change.
.
The rate of change is 3/4.
Therefore, the equation that describes the baby's weight is y = 3/4x + 8.
Answer:
y=1/2x+3.5
Step-by-step explanation:
look at any part of your slope where it crosses through a point: now go up your slope until you find the next point that the slope intersects. from your first point A, go up, then over until you reach point B. you just found your fraction for m. congrats
