Answer:
The probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525
Step-by-step explanation:

Standard deviation = 
We are supposed to determine the probability that a randomly chosen part has diameter of 3.5 inches or more

Refer the z table for p value

Hence the probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525
Answer:
y = 45 / 2x + 50
Step-by-step explanation:
The best equation for the line of the best fit would be y = 45 / 2x + 50.
The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).
I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.
I used those points because they were the most accurate ones that I know for now.
Also, remember the formula is, "y = mx + b."
Answer:
more than 7
Step-by-step explanation:
4+3 = 7
)sorry if i was wrong(
Im guessing it would be about 50 degrees
Answer:
Graph B
Step-by-step explanation:
y = (x - 3)(x - 3)
The x intercepts are at 3
Since both intercepts are at 3, the vertex is at 3
We know it is an upwards facing parabola since it is quadratic and the constant out front is positive
