The table shows the highs and lows in temperature over the last week in two towns in separate states. Which matrix shows the dif

ference in high and low temperatures between these two cities?

Answer:

  see attachment

Step-by-step explanation:

If we assume that the matrix is populated with (difference of high temperatures) in the first row and (difference of low temperatures) in the second row, we only need to look for one value.

The difference between the Monday high temperatures is 35 - 26 = 9 degrees. We expect that to be in the first row of the first column of the matrix we're looking for. We find that matrix in selection D.

Saira is using the formula for the area of a circle to determine the value of LaTeX: \piπ. She is using the expression LaTeX: Ar
lord [1]

Given:

Area of a circle, A=50.265 sq. units.

Radius of circle, r = 4 units.

To find:

The value of π to the nearest thousandth.

Solution:

Formula for area of a circle is

A=\pi r^2

\dfrac{A}{r^2}=\pi

Ar^{-2}=\pi

Now, using Ar^{-2} expression, we can find the value of π.

\pi=50.265904(4)^{-2}

\pi=\dfrac{50.265904}{4^2}

\pi=\dfrac{50.265904}{16}

\pi=3.141619

Approximate the value to the nearest thousandth (three digits after decimal).

\pi\approx 3.142

Therefore, the approximated value of π is 3.142.

The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters. (a) Determine the
maxonik [38]

Answer:

a) 0.5 = 50% of flanges exceed 1 millimeter.

b) A thickness of 0.96 millimeters is exceeded by 90% of the flanges

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:

P(X > x) = \frac{b - x}{b - a}

The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.

This means that a = 0.95, b = 1.05

(a) Determine the proportion of flanges that exceeds 1.00 millimeters.

P(X > 1) = \frac{1.05 - 1}{1.05 - 0.95} = \frac{0.05}{0.1} = 0.5

0.5 = 50% of flanges exceed 1 millimeter.

(b) What thickness is exceeded by 90% of the flanges?

This is x for which:

P(X > x) = 0.9

So

\frac{1.05 - x}{1.05 - 0.95} = 0.9

1.05 - x = 0.9*0.1

x = 1.05 - 0.9*0.1

x = 0.96

A thickness of 0.96 millimeters is exceeded by 90% of the flanges
