Part DWhat do the measures of angles BDA and BEA and the fact that AD and AE are radii of circle A tell us about BD and BE

Font Sizes

Answers

Answer:

BD and BE are tangents to the circle

Step-by-step explanation:

Given

See attachment

Required

What does BD and BE represent?

From the attachment, we have:

$\angle BDA = 90^\circ$

$\angle BEA = 90^\circ$

$Radii = AD\ and\ AE$

The measure of angles between a tangent and the radius of a circle is always $90^\circ\n$

So, because $\angle BDA = 90^\circ$ and AD is a radius, then BD is a tangent to circle.

Similarly,; $\angle BEA = 90^\circ$ and AE being a radius implies that BE is a tangent to circle.

A sample with which of these variances has a standard deviation that is greater than the variance?A. 2.25
B. 1.75
C. 0.75
D. 1.25

Answers

By using relation between standard deviation and variance we got that sample with 0.75 variance has a standard deviation that is greater than the variance

What is standard deviation?

Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value

Here we have to find a sample with standard deviation greater than the variance.

We know that Standard deviation is the square root of the variance so if we want a sample with greater Standard deviation than the variance then it's variance should be less than one as we know that if

$0 < x < 1 \Rightarrow \sqrt x > x$

And here given variances are

2.25, 1.75,0.75 and 1.25

Hence 0.75 is correct answer

By using relation between standard deviation and variance we got that sample with 0.75 variance has a standard deviation that is greater than the variance

Standard deviation is the square root of the variance. For the square root of a number to be greater than the number, the number must be between 0 and 1.
Hence, for the standard variation to be greater than the variance, the variance must be between 0 and 1.

Write an equation of a line with the given slope and y-intercept. m = –2, b = 4

Answers

Answer:

$y=-2x+4$

Step-by-step explanation:

The given data is

$m=-2$

$b=4$

Where $m$ is the slope of the line and $b$ is the y-intercept. So, basically this line has a slope of -2 and y-intercept at 4.

To find its equation, we use the slope-interception form

$y=mx+b$

Then, we replace each given value

$y=-2x+4$

Therefore, the equation for the given line is

$y=-2x+4$

y= -2x+4 m represents the x value and b the y intercept
