The line of best fit can be used to make predictions about the response variable based on the predictor variables. It can also be used to identify correlations between variables, as well as to estimate the strength of those correlations.

A. Line of Best Fit

A regression line is a statistical tool used to predict the value of a response variable based on the value of one or more predictor variables. It is also known as a line of best fit because it is used to show the best fit of a given data set. The line of best fit is a straight line that best represents the data by minimizing the sum of the squared distances between the observed data points and the line. The line of best fit can be used to make predictions about the response variable based on the predictor variables. It can also be used to identify correlations between variables, as well as to estimate the strength of those correlations.

Answer:

The solution of the equation is f(x)=-2x+3. Go into desmos graphing calculator and there is your answer.

Step-by-step explanation:

Hope this helps!

The graphical representation of f(x) = - 2(x + 4) + 5 is plotted. The slope of the line is -2 and y - intercept is -3.

The general equation of a straight line is -

y = mx + c

where -

m is the slope of line

c is the y - intercept

Given is a function → f(x) = - 2(x + 4) + 5

In order to plot the graph of this function, we will simplify the expression.

f(x) = - 2(x + 4) + 5

f(x) = -2x - 8 + 5

f(x) = -2x - 3

f(x) = (-2)x + (-3)

Now, we can plot this function on graph. Its slope will be -2 and y - intercept will be -3. Refer to the graph attached.

Therefore, the graphical representation of f(x) = - 2(x + 4) + 5 is plotted. The slope of the line is -2 and y - intercept is -3.

The given statement can be formulated as follows: A batch of 150 iPads is inspected by choosing a sample of four iPads. Eight of the 150 iPads do not conform to specifications.

How many samples of four contain exactly one non-conforming iPad?

Let's solve the given problem step by step.

Step 1: We have 8 non-conforming iPads and 142 conforming iPads in the batch of 150 iPads. We need to find the number of ways to choose 4 iPads that include exactly one non-conforming iPad.

Step 2: We choose one non-conforming iPad in 8 ways and choose 3 conforming iPads in 142C3 ways, where nCk is the number of ways to choose k objects from n distinct objects without regard to order.

Thus the total number of ways to choose 4 iPads with exactly one non-conforming iPad is given by:

=8 × 142C3

\(8 \times \frac{142 \times 141 \times 140}{3 \times 2 \times 1}\)

= 2,107,280

Therefore, there are 2,107,280 samples of four that contain exactly one non-conforming iPad.

Answer: Ben paid the most

Step-by-step explanation: Okay, to find the prices of the 4, we need to follow what the problem says. So, we know Hannah paid 21, so we know that is how much she paid. Now, we need to find 1/3 of the total cost ($64.80) So, we do 1/3 divided by $64.80 and get $21.60. For Stephanie, we need to find 15% of $64.80, so we can write it as a proportional relationship, so 15 x $64.80 / 100 is 9.27. (as a decimal) Now, we subtract all of those numbers from the total cost ($64.80) to find Brayden's pay. After I subtracted all of the amounts, I got $12.93. I'll list all the amounts.

Hannah - 21

Ben - 21.60

Stephanie - 9.27

Brayden- 12.93

So, as we see Ben paid the most. I hoped this LONG explanation helped you!

it should be ben.

Hannah paid $21;

ben paid 1/3 of 64.80 and that's $21.6 (64.84÷3);

Stephanie paid 15% of $64.80 and that's $9.72 (15÷100×64.80);

Brayden paid $12.48 [64.80-(21+21.6+9.72)].

The probability that the chosen adult have high school or some college degree but no college degree is 0.683.

From the definition of probability we know that,

Probability of Event = (Outcomes favorable to that event)/(Total number of outcomes under that event)

Total number of adults in the town is given by = 4286 + 6313 + 3033 + 1886 = 15518.

The number of adults have high school degree only = 4286

The number of adults have some college degree only = 6313

The number of adults have high school or some college degree but no college degree = 4286 + 6313 = 10599.

The probability that the chosen adult have high school or some college degree but no college degree is given by

= 10599/15518 [According to definition of probability]

= 0.683 [Rounding off to nearest thousandth]

Hence, probability that the chosen adult have high school or some college degree but no college degree is 0.683.

The question is incomplete. The complete question will be -

The correct statement is c. The Adjusted R-squared is a measure used in multiple regression analysis that is between 0 and 1. It is different from the R-squared value in simple linear regression.

The Adjusted R-squared can decrease if the addition of another X regressor does not sufficiently lower the sum of squared residuals (SSR) relative to the impact of increasing the number of predictors (k). It measures the proportion of the variance explained by the predictors, adjusted for the number of predictors and the sample size, rather than the ratio of the sum of squared residuals to the total sum of squares. It provides a measure of how well the regression model fits the data, and it ranges between 0 and 1. A value closer to 1 indicates that a higher proportion of the variance in the dependent variable is explained by the predictors.

Adding another X regressor to the multiple regression model can impact the Adjusted R-squared. If the additional regressor does not significantly contribute to reducing the sum of squared residuals (SSR) relative to the increase in the number of predictors (k), the Adjusted R-squared can decrease. This means that the added regressor does not improve the model's ability to explain the variance in the dependent variable adequately.

However, the Adjusted R-squared does not directly measure the ratio of the sum of squared residuals to the total sum of squares. Instead, it represents the proportion of the variance explained by the predictors, adjusted for the number of predictors and the sample size. It penalizes models with a large number of predictors that may overfit the data, thereby providing a more reliable measure of the model's goodness of fit.
