Ainat [17]

Answer:

\Huge\boxed{z

Step-by-step explanation:

Hello There!

Once again we need to isolate the variable using inverse operations

to get rid of the -8.2 we add 8.2 to each side

-8.2+8.2 cancels out

-9.7+8.2=-1.5

now we have

-1.2z>-1.5

now we wan to get rid of the -1.2

to do so we want to divide each side by -1.2

\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25

Remember we have to flip the inequality sign because we're dividing by a negative number

we're left with

z<1.25

For simple linear regression, y = β0 + β1x + u, which one of the following statements is true?
RSB [31]

Answer:

Option a) u is called the "error term". It is the error we make in prediction

Option d) x is called the independent variable because x is independent from y and u.

Step-by-step explanation:

We are given the following information in the question:

y = \beta_0 + \beta_1x + u

where y is the dependent variable, x is the independent variable.

\beta_0: It is the value of y when x is zero, that is y-intercept.

\beta_1: It is the coefficient of x in predicting the dependent variable y.

u is the error term.

  • An error term represents the margin of error.
  • It refers to the sum of the deviations within the regression line, that is the difference between the predicted value and the observed value of y.

Thus, Option A) u is the error term and Option D)  x is called the independent variable because x is independent from y and u are the correct answer.

Tom [10]

Yasim is Albert who ran the race at a time that was 15.7 seconds shorter, So, Yasim is the student who improved the most by decreasing the time needed to run the race.

<h2>Given that,</h2>

Coach Burns charted the change in his runners' 5K times from the first race of the year to the second race of the year.

<h3>We have to find,</h3>

Which student improved the most by decreasing the time needed to run the race?

<h3>According to the question,</h3>

Coach Burns charted the change in his runners' 5K times from the first race of the year to the second race of the year.

In the given option Yasim has the lowest value of the time which is -37.5 seconds.

Yasim was the most improved student because Yasim ran the second race in a time that was 37.4 seconds shorter than the first race.

Following Yasim is Albert who ran the race at a time that was 15.7 seconds shorter.

At the third place in improvement is Cody who actually was worse off than the first race along with the 4th place Hannah.

Hence, Yasim students improved the most by decreasing the time needed to run the race.

In a recent season, hockey player Sidney Crosby scored 42 goals in 76 games he played. Assume that his goal production stayed at
cestrela7 [59]
Hello,

First, 42 goals in 76 games can be written as the following proportion:
42/76

Next, after finding 42/76, multiply by 100% to have the probability that Sidney would get his first goal in the first game.

42/76 * 100% = 55% (rounded)

Good luck to you!
