Graph the three points and connect them to create the mid segments of the triangle:

Use midsegments of triangles in the coordinate plane.

Use the Triangle Midsegment Theorem to fi nd distances.

Using the Midsegment of a Triangle

A midsegment of a triangle is a segment that connects the

midpoints of two sides of the triangle. Every triangle has

three midsegments, which form the midsegment triangle.

The midsegments of △ABC at the right are MP —, MN —,

and NP —. The midsegment triangle is △MNP.

The value of p in the equation is as follows:

The subject of a formula is the variable which is expressed in terms of the other variables.

In other words, the subject of the formula is the variable which is on the left hand side of the formula.

Therefore, let's make p the subject of the formula in the equation xp - rx = ah.

xp - rx = ah

add rx to both sides of the equation

xp - rx = ah

xp - rx  + rx = ah + rx

xp = ah + rx

divide both sides by x

xp = ah + rx

xp / x = ah / x + rx / x

Therefore, the value of p = ah / x + r

The smallest degree of rotation that will map a regular 16-agon onto itself is 22.5 degrees.

What is a degree?

A degree is a unit of measurement used to express angles. It is defined as 1/360th of a full rotation, or 1/2π radians.

To see this, note that a regular 16-agon has 16 sides, and each angle between sides measures 180(16-2)/16 = 135 degrees. Therefore, to rotate the 16-agon so that it maps onto itself, we must rotate it an integer multiple of 135 degrees.

However, we want the smallest such angle, so we must find the smallest integer multiple of 135 degrees that is greater than or equal to 360 degrees (since a full rotation maps the figure onto itself). The smallest such multiple is 2, which is equal to 270 degrees.

The smallest degree of rotation that will map the 16-agon onto itself is 270 degrees / 2 = 135 degrees / 2 = 22.5 degrees.

Hence, The smallest degree of rotation that will map a regular 16-agon onto itself is 22.5 degrees.

Step-by-step explanation:

If Kayla's work is the sum of all the numbers, she is calculating the mean.

2327 is the minimal number of consumers that should be sampled by the advertiser to be 95% confident that their estimate will fall within 2% of the genuine population proportion.

Given that,

TV viewers frequently doubt the validity of particular advertising. In an attempt to counter their critics, a large advertiser wants to determine the true proportion of consumers who believe what is depicted in ads. About 40% of individuals examined, according to preliminary studies, seem to believe what is depicted in advertisements.

We have to find what is the minimal number of consumers that should be sampled by the advertiser to be 95% confident that their estimate will fall within 2% of the genuine population proportion.

We know that,

Let

Population proportion (p)= 0.40

Margin of error = 2% = 0.02

Confidence level = 95% = 0.95

α = 1- 0.95 = 0.05

α/2 = 0.025

Let's find out the Z critical value using excel for the 95% confidence level,

Use the following excel command.

= ABS(NORMSINV(α/2))

= ABS(NORMSINV(0.025))

We will get, Z critical value = 2.17009

Sample size (n) = p(1-p)×(Zα/2)/E

n = 0.40(1-0.40)({2.17009}÷{0.05})²

Sample size (n) = 2327

Therefore, 2327 is the minimal number of consumers that should be sampled by the advertiser to be 95% confident that their estimate will fall within 2% of the genuine population proportion.

95.1% of the proportion of observed variation in hardness can be explained by the simple linear regression model relationship between hardness and elapsed time.

Linear regression model:

In statistics, linear regression model defined the relationship between a dependent variable, y, and one or more independent variables, X.

Given,

Here we need to find the percentage of observed variation in hardness can be explained by the linear relationship between hardness and elapsed time.

In order to find the percentage we must know the definition of observed variation which means  the combined variation that is derived from all sources.

In order to solve this let us consider that the linear regression model is used by statisticians to predict the value of the response variable for given values of the predictor variables.

So, if there are two variables involved in the regression analysis, then the model is called a bivariate one.

Where as If there are more than two independent variables, then the regression model is known as the multiple regression model.

The probability that he will serve exactly four aces out of seven serves is 5.7 %.

Given :

if the probability that a certain tennis player will serve an ace is 1 / 4 .

If we let p stand for the probability of a succes, then p = 1/4, and ( 1 - p ) = 3/4.  (1-p) is the probability that he will NOT serve an ace.

Formula  for probability:

P (m successes in n trials) = ( nCm ) * p^m * ( 1 - p )^( n - m ).

= 7C4 * ( 1/4 )^4 * ( 3/4 )^( 7 - 4 )

= 7! / ( 7 - 4 )! 4! * 1/256 * 27/64

= 7 * 6 * 5 / 3 * 2 * 1 / 256 * 27/64

The standard deviation is 4.95.

The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each value lies from the mean.

A high standard deviation means that values are generally far from the mean, while a low standard deviation indicates that values are clustered close to the mean. The standard deviation and the mean together can tell you where most of the values in your frequency distribution lie if they follow a normal distribution.

Dataset: 1,2,4,7,8

So, n = 5 (because the sample size is 5)

We calculate the mean X by taking the average of the data values, which is dividing the sum of the data values by the number of data values:

X = 1+2+4+7+8/5

X=22/5 = 4.4

So, the average is 4.4

For standard deviation calculation,
