Please help, 25 points. Will mark brainliest if correct :)

Given:

The equation of the line of best fit is :

[tex]y=4.722392638x+50.99539877[/tex]

To find:

The x-intercept and check whether it make sense in this context.

Solution:

We have,

[tex]y=4.722392638x+50.99539877[/tex]

Substitute [tex]y=0[/tex] to find the x-intercept of the given best fit line.

[tex]0=4.722392638x+50.99539877[/tex]

[tex]-50.99539877=4.722392638x[/tex]

[tex]-\dfrac{50.99539877}{4.722392638}=x[/tex]

[tex]-10.7986359202=x[/tex]

So, the x-intercept is at point (-10.7986359202,0). It means the score on final examination is 0 if -10.7986359202 hours  spent on studying.

But is does not make sense because the number of hours cannot be negative.

Answer:

y = 3x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, - 1) and (x₂, y₂ ) = (5, 5)

m = [tex]\frac{5+1}{5-3}[/tex] = [tex]\frac{6}{2}[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (5, 5 ) , then

5 = 15 + c ⇒ c = 5 - 15 = - 10

y = 3x - 10 ← equation of line

It's D. the median for town A, 30, is less than the median for town B, 40.

The median for town A at 30° is less than the median for town B at 40°.

So, option (D) is the correct answer.

The median is the "middle" of a sorted list of numbers. To find the median, place the numbers in value order and find the middle number".

For the given diagram,

Town A has temperatures = 20°, 30°, 40°

Town B has temperatures = 30°, 40°, 50°

The median of A = 30°

The median of B = 40°

Hence, From the above values, the median for town A at 30° is less than the median for town B at 40°.

Hence, we can conclude that option (D) is the correct answer.

Answer:

Step-by-step explanation:

Area of a parallelogram is base x height

The base of the given parallelogram is 9 inches and the height is 7.5 inches

So, its area would be

9 x 7.5

Area equals [tex]67.5^{2}[/tex]

Answer:

area = 432 ft²

Step-by-step explanation:

area = 1/2(B1 + B2)(H)

area = 1/2(20 + 16)(24) = 432 ft²

Answer:

It is equivalent to w+w

Step-by-step explanation:

w+w= 2w

Answer:

A w+w

Step-by-step explanation:

because 2w means 2 * w ( 2 times w)

when you multiply 2 time any number, you add that number twice,

exp... 4 times 2 = 4 + 4

therefore 2w is also w+ w

Area= 2560      Perimeter= 208

Step-by-step explanation:

Answer:

64 x 40 = 2,560 <------- your area because multiply the two given lengths.

64 + 64 + 40 + 40 = 208 <---------- your perimeter since opposite sides are parallel which means 2 sides are different. So two of both of the different lengths will be your perimeter.

Answer:

Option A,  9b + 10s is correct

Step-by-step explanation:

The complete question is

At cycle and sport customers can rent bikes, electric scooters, kayaks, canoes, or paddleboards by the hour. Ari is renting a bi ke, and meg is renting an electric scooter. Which expression represents the total cost for Ari to rent a bike for b hours and Meg to rent a scooter for s hours (Please answer ASAP) A. 9b + 10s B. 9 + 10 C. (9+b) + (10 + s) D. 9 + 10 x b + s  

Solution

The price of renting a bike for one hour is $9

The price of renting a scooter for one hour is $10

Given -

Ari rents a bike for b hours and Meg rents a scooter for s hours

Total cost of renting a bike is 9 * b

Total cost of renting a scooter is 10* s

The total cost of renting both the bike and scooter is

9b + 10s

Hence, option A is correct

Answer:

640

Step-by-step explanation:

Since 15 out of every 75 fish are more than 30 cm long, the probability of finding a fish more than 30 cm is P(x > 30) = 15/75 = 1/5.

The probability of finding a fish 30 cm or less is P(x ≤ 30) = 1 - P(x > 30)

= 1 - 1/5

= (5 - 1)/5

= 4/5

Since we have 800 fish and the probability of finding a fish 30 cm or less is P(x ≤ 30) = 4/5, then the number of fish in the population that are 30 cm or less in length are 800 × P(x ≤ 30) = 800 × 4/5

= 160 × 4

= 640

So, 640 fish in the population are 30 cm or less in length

Answer:

$13.05

Step-by-step explanation:

Given: Mark and his 3 friends = 4 Total cost = $52, percent off: 20%

To find: How much each person would pay if they split the bill evenly.

Solution:

Firstly, since they left the server a 20% tip, multiply 20% by the total cost. Convert it to a fraction. Note: you're adding 20% to the total cost.

                                                    [tex]\frac{20}{100}[/tex] + [tex]\frac{52}{1}[/tex]

                                                      = [tex]_{52.2}[/tex]

Now, that is done, let's divide the newly found cost by the four friends.

                                                     [tex]\sqrt[4]{52.2}[/tex]

                                                   = [tex]{13.05}[/tex]

So, they would pay $13.05 evenly.
