The graph below shows the relationship between the number of months different students practiced tennis and the number of matches they won:

Part A: What is the approximate y-intercept of the line of best fit and what does it represent?

Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope.

Answers

Answer:

(a) (i) y-intercept = 3

    (ii) Represents that the team won 3 matches without any practice.

(b) (i) Equation: y = 1.8x + 3,  

    (ii) 26 matches won

The approximate y-intercept can be determined by seeing when the best fit line crosses the y axis.

Part A

Here the best line crosses the y-axis when y = 3. So coordinates: (0, 3)

Part B

Take two best points touching the line: (0,3), (5, 12)

[tex]\sf slope \ (m) = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{12-3}{5-0} = 1.8[/tex]

Equation:

y - y₁ = m(x - x₁)

y - 3 = 1.8(x - 0)

y = 1.8x + 3

So, after 13 months of practice: y = 1.8(13) + 3 = 26.4 ≈ 26 matches won.

#1

The y intercept should represent how much matches the team won without practice

Here its 3

You wish to take a flight from Nevada to New York. Use the point (-4, 0) to represent Nevada, and the (5, 2) to represent New York. The airline has partitioned the flight so that you have a layover. The flight distance is partitioned in a ratio of 3:1. Determine the ordered pair that represents the location of the layover.

Answers

Using proportions, it is found that the ordered pair that represents the location of the layover is (3.75, 1.5).

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The flight distance is partitioned in a ratio of 3:1, hence, for both the x and y coordinates, we have that:

L - Nv = 3/4(Ny - Nv)

For the x-coordinate, we have that:

[tex]x + 4 = \frac{3}{4}(5 + 4)[/tex]

[tex]x = \frac{27}{4} - \frac{16}{4}[/tex]

[tex]x = \frac{11}{4}[/tex]

x = 3.75

For the y-coordinate, we have that:

[tex]y = \frac{3}{4}(2)[/tex]

[tex]y = \frac{6}{4}[/tex]

y = 1.5.

Estimate the amount of time she spent at ballet to the nearest hour

Answers

The amount of time that Lila spent at Yoga and Ballet are approximately equal to 26 hours and 13 hours respectively.

How to calculate the time spent?

First of all, we would calculate the amount of time that Lila spent at Yoga by multiplying the total time spent by the percentage of time spent on Yoga as follows:

Yoga time = 92 × 28/100

Yoga time = 92 × 0.28

Yoga time = 25.76 26 hours.

Part B.

Next, we would calculate the amount of time that Lila spent at Ballet by multiplying the total time spent by the percentage of time spent on Ballet as follows:

Answers

What is Permutations?

A permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements.

Here, total number of cards = 52

         Number of Withdrawn cards = 3

Possibilities of different sequences of 3 playing cards = 52 X 51 X 50

                                                                                          = 132600

#SPJ1

Answer:

132,600

Step-by-step explanation:

To determine the number of different sequences of 3 playing cards from a 52-card deck, we can use the formula for permutations, which is given by:

P(n, k) = n! / (n-k)!

Where n is the total number of items (in this case, the number of cards in the deck) and k is the number of items chosen (in this case, 3 cards).

Plugging in the values:

n = 52 (total number of cards in the deck)

k = 3 (number of cards chosen)

P(52, 3) = 52! / (52-3)!

Calculating the factorial terms:

52! = 52 x 51 x 50 x ... x 3 x 2 x 1

(52-3)! = 49! = 49 x 48 x ... x 3 x 2 x 1

Simplifying the equation:

P(52, 3) = 52 x 51 x 50

P(52, 3) = 132,600

Therefore, there are 132,600 different sequences of 3 playing cards that can be formed from a single 52-card deck.

y=3

plug in y into one of the equations

4x + 3 = 19

4x=16

x=4

Hope this helps!

If not, I am sorry.

Answer:

(4, 3 )

Step-by-step explanation:

4x - 2y = 10 → (1)

4x + y = 19 → (2)

subtract (1) from (2) term by term

(4x - 4x) +y - (- 2y) = 19 - 10

0 + y + 2y = 9

3y = 9 ( divide both sides by 3 )

y = 3

substitute y = 3 into either of the 2 equations and solve for x

substituting into (2)

4x + 3 = 19 ( subtract 3 from both sides )

4x = 16 ( divide both sides by 4 )

x = 4

solution is (4, 3 )

Answers

Answer:

Step-by-step explanation:

(a)

the sum of the 3 angles in the triangle = 180° , then

∠ A = 180° - 90° - 48° = 180° - 138° = 42°

(b)

using the tangent ratio in the right triangle

tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{y}{10}[/tex] ( multiply both sides by 10 )

10 × tan48° = y , then

y ≈ 11.1 units ( to the nearest tenth )

(c)

using the cosine ratio in the right triangle

cos48° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{10}{x}[/tex] ( multiply both sides by x )

x × cos48° = 10 ( divide both sides by cos48° )

x = [tex]\frac{10}{cos48}[/tex] ≈ 14.9 units ( to the nearest tenth )


Five people, each working 8 hours a day, can assemble 400 toys in a 5-day work week. What is the average number of toys
assembled per hour, per person?
A 2
B 4
C 8
D 16

Answers

Answer:

A. 2

Step-by-step explanation:

First divide the 400 toys by the 5 people to see how many each did:

400 toys/5 people = 80 toys/person

Next let's see how many hours were worked by multiplying the hours per day by the number of days worked:

5 days x 8 hours/day

40 hours

Now to find how many toys were assembled per hour per person, let's divide the toys/person by the number of hours they each worked:

[tex]\frac{80 toys/person}{40 hours}[/tex]=2 toys/person/hour

The average number of toys per person per hour is 2.

What is Ratio?

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

Total number of toys assembled = 400

Total days of work = 5  

Each person work daily for = 8 hrs

Total number of people = 5

Then, the total toys assembled per day

400/5= 80

The number of hours worked by the 5 workers per day = 8 × 5= 40

So, the number of toys assembled per person per hour = 80 / 40= 2

Hence, the average number of toys per person per hour is 2.

So if the number in front is negative that will flip it upside down, over the x-axis.

If the number is greater than 1, the function will be vertically stretched, narrower, slimmer, skinnier, taller.
