Answer:
centimeter
Step-by-step explanation:
Miles is a measure of distance, so the commensurable measure will also be a distance measure.
acres - area measure
kilograms - mass measure
hours - time measure
centimeter - distance measure
V = pi(r)^2(h)
Answer with pi substitute (3.14):
4 * 4 = 16
3.14 * 16 * 4
V = 200.96
Answer without pi substitute:
4 * 4 = 16
v = pi(16)(4)
v = 64pi
Answer:
all of the above
Step-by-step explanation:
Pareallell lines have same slope
y=mx+b, m=slope
y=3x-8 so we need
y=3x+b
find b
so given (4,-5)
we can subsitute the point
(x,y)
(4,-5)
x=4 then y=-5
so
-5=3(4)+b
-5=12+b
-17=b
y=3x-17 is equation
D is answer
Answer:
0.0668 = 6.68% of ball bearings has a diameter more than 5.03 mm
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Manufacturing Ball bearings are manufactured with a mean diameter of 5 millimeters (mm).
This means that
With a standard deviation of 0.02 mm.
This means that
(a) What proportion of ball bearings has a diameter more than 5.03 mm
This is 1 subtracted by the pvalue of Z when X = 5.03. So
has a pvalue of 0.9332
1 - 0.9332 = 0.0668
0.0668 = 6.68% of ball bearings has a diameter more than 5.03 mm
