The absolute value of a number is the distance it is from 0. The bug is currently to the left of 0 and the absolute value of its
Ksenya-84 [330]

Answer:

- 4

Step-by-step explanation:

The absolute value of a number renders a number positive regardless of the preceeding sign. Therefore, either a number is positive or negative, the absolute value of such number will be positive.

In a number line, 0 is the midpoint and values to the left of 0 are negative, while those to the right are positive.

For the scenario, above, the bug is to the left of 0 and has an absolute value of 4 ;

The current position of the number line will be 4 (absolute value) places to the left of 0 which is - 4 (negative numbers are in the left).

Ball-Bearings, Inc. produces ball bearings on a Kronar BBX machine. For one specific ball bearing produced, the mean diameter is
worty [1.4K]

Answer:

3.59% of the ball bearings will have diameters of 20.27 mm or more.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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.

In this problem, we have that:

\mu = 20, \sigma = 0.15

What percent of the ball bearings will have diameters of 20.27 mm or more?

This is 1 subtracted by the pvalue of Z when X = 20.27. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{20.27 - 20}{0.15}

Z = 1.8

Z = 1.8 has a pvalue of 0.9641.

1-0.9641 = 0.0359

3.59% of the ball bearings will have diameters of 20.27 mm or more.

Easy question, Easy points LIMTED TIME. LOTS OF POINTS<br><br> Topic: Volume
DedPeter [7]

Answer:

V = 77 m^3

Step-by-step explanation:

We want the volume of the cylinder

V = pi r^2 h

We know the diameter not the radius

r = d/2 = 7/2 = 3.5

V = 3.14 * (3.5)^2 (2)

V = 76.93 m^3

To the nearest cubic meter

V = 77 m^3
