6 0

If the recipe makes enough stew for 6 people, and the ingredients cost $9.75, then for 24 people it will cost $x. You can write this statement as

6 people - $9.75,

24 people - $x.

Or as proportion,

$\dfrac{6}{24}=\dfrac{9.75}{x}.$

Find x:

$6\cdot x=9.75\cdot 24,\\ \\x=\dfrac{9.75\cdot 24}{6}=9.75\cdot 4=39.$

Answer: It would cost $39 to serve 24 people

Task 1

CaHeK987 [17]

Answer:

part 1 : y = x^2 + 3x + 5

y = x + 13

solution:

x^2 + 3x + 5 = x + 13

x^2 + 2x -8 = 0

(x+4)(x-2) = 0

x = -4 or x = 2

if x = -4, y = 9

if x = 2 , y = 15

part 2 : x^2 + 2x + 1 = 0

(x + 1)^2 = 0

x = -1

y = 1

task 2

part 1 : Let our two digit number be 26

Next, we rewrite it as a difference of two numbers

26=32-6

We want to square 26 using the identity:

In this case,

x=32

y=6

Substituting into the identity

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. E. None of these.

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;

E. None of these
