1. So far, Marta has correctly predicted the winner of 6 out of 13 football games. She wants to know how many consecutive games she would have to predict correctly to raise the percent of correct predictions to 65%. (a) Write an equation to represent this situation. (3 points) (b) Solve the equation. Show all steps. (5 points) (c) Answer the question. How many consecutive games must she predict correctly to raise her percent to 65%? (1 point)

Answers

Answer 1

Answer:

[(6 + x) / 13+x] = 0.65

7

Step-by-step explanation:

Given that:

Total number of games = 13

Number of correct prediction = 6

Number of correct predictions needed to raise prediction % to 65%

(Number of correct predictions) / (total number of games) = 0.65

Let x = number of additional consecutive correct predictions

[(6 + x) / 13+x] = 0.65

Where x = number of consecutive predictions required

6 + x = (13 + x) * 0.65

6 + x = 8.45 + 0.65x

x - 0.65x = 8.45 - 6

0.35x = 2.45

x = 2.45 / 0.35

x = 7

7 consecutive correct predictions

Find the area of the figure

Answers

Answer:

45 I'm pretty sure. so it 45

Answer:

The figure is 5.5in^2.

Step-by-step explanation:

To find the area of the triangle portion, we will use the formula for area of a triangle, [tex]\frac{bh}{2}[/tex], where b = base and h = height.

So lets find our variables,

b = 3

h = 3

So we can plug that into our equation and find the area,

3 · 3 = 9 and 9 ÷ 2 = 4.5

So the area of the triangle is 4.5in^2

To find the area of the square portion, we will use the formula for the area of a square or rectangle, l · w, where l = length and w = width

So lets find our variables,

l = 1

w = 1

So 1 · 1 = 1in^2

To find the total area we will add the areas of the two components together,

4.5 + 1 = 5.5in^2

So the area of the total figure is 5.5in^2.

Answers

Answer:

x=−27/26

and y=−192/13

Step-by-step explanation:

6x+y=−21;8x−3y=36

Step: Solve6x+y=−21for y:

6x+y=−21

6x+y+−6x=−21+−6x(Add -6x to both sides)

y=−6x−21

Step: Substitute−6x−21foryin8x−3y=36:

8x−3y=36

8x−3(−6x−21)=36

26x+63=36(Simplify both sides of the equation)

26x+63+−63=36+−63(Add -63 to both sides)

26x=−27

Xavier created a scatterplot and a trend line for data that he collected by comparing the number of minutes he spent playing a game and the number of levels he passed.

A) 2 minutes played and 3 levels passed

B) 17 minutes played and 35 levels passed

C) 20 minutes played and 9 levels passed

D) 50 minutes played and 19 levels passed

Answers

Answer:

Option (C)

Step-by-step explanation:

By using regression line calculator,

Equation of the regression line will be,

y = 0.4881x - 0.85714

Here y = Levels passed

x = Number of minutes played

Now we can check every option given.

Option (A)

For x = 2 minutes,

y = 0.4881(2) - 0.85714

  = 0.11906

  ≈ 0.1

False.

Option (B)

For x = 17 minutes,

y = 0.4881(17) - 0.85714

  = 8.2971 - 0.85714

  = 7.44

  ≈ 7th level

False.

Option (C)

For x = 20 minutes

y = 0.4881(20) - 0.85714

  = 9.762 - 0.85714

  = 8.9

  ≈ 9th level

True.

Option (D)

For x = 50 minutes,

y = 0.4881(50) - 0.85714

  = 24.405 - 0.85714

  = 23.54786

  ≈ 24th level

False.

Therefore, Option (C) will be the correct option.

Martin buys enough juice to last for 2 weeks (14 days).

What is the lowest price Martin can pay for this juice?

Answers

Given :

Martin drinks 1/4 of a litre of juice each day.

Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.

To Find :

Martin buys enough juice to last for 2 weeks (14 days).

What is the lowest price Martin can pay for this juice.

Solution :

Amount of litre used in 14 days is :

V = 14× ( 1/4 )

V = 3.5 liter

Lowest price to pay is :

P = 2 × Cost of one 2 L carton

P = £(2 × 3.60)

P = £7.2

The lowest price Martin can pay for this juice is £7.2 .

Hence, this is the required solution.
