Answer:

The total people in the Engel family who went to the zoo is 6.

Step-by-step explanation:

The admission for each person =$50

Parking fee = $16

Let us assume the total member who go to zoo = m

So, Total ticket price for m people = m x (Price of each ticket)

= m x ($500= 50 m

Total money spent by the family =  $ 316

⇒  Parking Fee + Money spent on m tickets  = Total money = $316

⇒ 16 + 50 m = 316

or, 50 m = 316 - 16  = 300

⇒ m = 300 / 50 = 6

or, m = 6

Hence the total people in the engel family  who went to  zoo is 6.

In a teacher's math course, a linear regression line was calculated to predict
Marat540 [252]

The given equation is the best line that approximates the linear

relationship between the midterm score and the score in the final exam.

  • AJ's residual is 0.3, which is not among the given options, therefore, the correct option is. <u>E. None of these</u>.

Reasons:

The given linear regression line equation is; \hat y = 25.5 + 0.82·\mathbf{\hat x}

Where;

\hat y = Final exam score;

\hat x = The midterm score;

AJ score in the first test, \hat x = 90

AJ's actual score in the exam = 99

Required:

The value of AJ's residual

Solution:

By using the regression line equation, we have;

The predicted exam score, \hat y = 25.5 + 0.82 × 90 = 99.3

  • The residual score = Predicted score - Actual score

∴ AJ's residual = 99.3 - 99 = 0.3

AJ's residual = 0.3

Therefore, the correct option is option E;

  • <u>E. None of these</u>
