Answer:

The residual e=2 when x = 5.

Step-by-step explanation:

A scatter plot containing the point (5, 29), it means the observed value at x=5 it 29.

The given regression equation is

\hat{y}=5x+2

Substitute x=5 in the above regression equation, to find the predicted value at x=-5.

\hat{y}=5(5)+2=25+2=27

The formula to find the residual value e is

e = Observed value - Predicted value

e=29-27

e=2

Therefore the residual e=2 when x = 5.

The given number sentence is simplified as 1 3/5

<u>Step-by-step explanation:</u>

The given number sentence is 2-4/5 x 1/2

  • In order to solve this, the operations must be performed based on the BODMAS rule.
  • This means that, the operations should be performed in the order of Bracket, Of, Division, Multiplication, Addition and Subtraction.

Here, based on that above rule, the multiplication must be done in the first step and then subtraction should be done in the next step.

⇒ 2 - 4/5 × 1/2

⇒ 2 - 4/10

⇒ 2 - 2/5

Therefore, the given expression is reduced to 2- 2/5

cross multiply the denominator 5

⇒ (10-2) / 5

⇒ 8/5

Now, the expression is reduced to single term 8/5.

To further reduce the term, divide 8 by 5.

  • The quotient is 1.
  • The remainder is 3.
  • The divisor is 5.

The answer is written in the form of Quotient(Remainder/ divisor)

⇒ 1 3/5

Harry saved $100 each week for 8 weeks. He earned $48 on his savings of $800. What interest did Harry earn for every $100?
ch4aika [34]
<h2>Explanation:</h2><h2></h2>

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

\text{Amount of money saved}=8\times 100=\$800

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

I=\frac{48}{8}=\$6

So, in conclusion Harry did earn $6 in interest for every $100
