A scatterplot is used to display data for a runner where x is the number of miles run, and y is the time, in minutes, that it
takes to run that distance.
Which interpretation describes a line of best fit of y = 9.5x for the data in the scatterplot?
For each 1 minute, the runner ran 9.5 miles.
The missing choices are:
(A) for each 1 minute, the runner ran 9.5 miles.
(B) for each 9.5 minutes, the runner ran 1 mile.
(C) the minimum distance with a recorded time is 9.5 miles.
(D) the maximum distance with a recorded time is 9.5 miles.
Answer:
The interpretation that describes the line best fit of y = 9.5 x is: for each 9.5 minutes, the runner ran 1 mile. ⇒ (B)
Step-by-step explanation:
Since the equation of the line best fit is y = 9.5 x, where
x is the number of miles runy is the time in minutes9.5 is the rate of change of the time to the mileThe rate of change = change of y/ change of x
∵ y represents the time in minutes
∵ x represents the distance in miles
∴ The rate of change = minutes / mile
∵ The rate of change = 9.5 minutes / 1 mile
∴ The interpretation describes the line best fit is:
For each 9.5 minutes, the runner ran 1 mile

Grayson works in a department store selling clothing. He makes a guaranteed salary
of $350 per week, but is paid a commision on top of his base salary equal to 20% of
his total sales for the week. How much would Grayson make in a week in which he
made $925 in sales? How much would Grayson make in a week if he made x dollars
in sales?
Step-by-step explanation:
a) $350 per week
20% commission on sales
For $925 in sales, commission is
20/100 × 925 = $185
Total earning = $350 + $185 = $535
b) For $x in sales, commission is
20/100 × x = 1/5 × x = x/5 or 0.2x
Total earnings = $350 + $ x/5 or $350 + $0.2x
The expression x-2 has a value of -5 for some value of x. For the same value of x, what is the value of the expression (x-2)²+5x-10? Show your reasoning for this problem in the space provided.
(1) 0 (2) 15 (3) 14 (4) -10
Answer:
-10
Step-by-step explanation:
Assuming that x-2=-5, we can subtitute it into the equation as follows:
(-5)^2 + 5(-5) - 10, we start off with the exponent according to the order of operations resulting in:
25 + 5(-5) -15, then we do the multiplication next:
25 + (5 * -5 = -25) so:
25 + -25 - 10, the 25s cancel each other out and your left with:
0 - 10 which equals -10

Domain: [-6,8]
Range: [-7, 8]
Step-by-step explanation:
My answer is written in interval notation.
Domain:
The domain is all the possible x values the function has. if you look at the graph, the x values do not pass -6 when going left, and it also does not pass 8 when going right. filled in circles means that point is included, which is why I used brackets instead of parenthesis.
Range:
The range is all the possible y values the equation can have. If you look at the graph, the graph does not have a point that goes below -7, or above 8. filled in circles means that point is included, which is why I used brackets instead of parenthesis.
*make sure to put the lower number first, which is why I put the negative numbers then the positive ones.
Bob's Bagels offers pre-paid cards and has the specials shown. Carol has a $50 card she uses to buy coffee and a bagel each week. Diego has a $60 card he uses to buy tea and a breakfast sandwich each week. Write and solve an inequality to find the number of weeks in which the balance on Carol's card will be greater than the balance on Diego's card.
Answer:
50-3W ≤ 60-5w
Number of week = 5 days
Step-by-step explanation:
Given:
Carlo card = $50
Diego card = $60
Note:
Coffee and Bagel = $3
Tea and breakfast sandwich = $5
Computation:
Number of week = W
50-3W ≤ 60-5W
Number of week = 5 days
During the summer, you work 40 hours per week at a coffee shop and eam $9.25 per hour. You also tutor for $10.00 per hour and can work as many hours as you want. You want to earn a total of $425 per week. How many hours must you tutor?
Answer:
6 hours worked as a tutor
Step-by-step explanation:
40 x 9.25 = 370$
425 - 370 = 55
55/10 = 5.5
so 5.5 but because you work full hour round up to 6 hour worked as a tutor
An equation is formed of two equal expressions. The number of hours you must tutor to earn $425 is 5.5 hours.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that you work 40 hours per week at a coffee shop and earn $9.25 per hour. You also tutor for $10.00 per hour and can work as many hours as you want. Therefore, we can write the total earnings as,
Total earning = Earning from the coffee shop + Earning from the tutoring
Total earning = ($9.25 × 40 hours) + ($10 + x number of hours)
It is also given that You want to earn a total of $425 per week. Therefore, we can write,
Total earning = ($9.25 × 40 hours) + ($10 + x number of hours)
$425 = ($9.25 × 40) + $10x
Solving the equation for x,
$425 = $370 + $10x
$425 - $370 = $10x
$55 = $10x
x = 55/10
x = 5.5
Hence, the number of hours you must tutor to earn $425 is 5.5 hours.

Step-by-step explanation:
Work it out smh
The probability that there is a left-handed person in a group of 5 randomly selected people is 6%
It is given that Greta learned that about 10% of people are left-handed.
It is required to find the probability that there is a left-handed person in a group of 5 randomly selected people.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a total number of people = 50 (because 10 rows and 5 columns)
In the question, it is given that the 0 represents a left-handed person.
Then the number of left-handed people = 3 (there are three zero's in the table)
We know:
[tex]\rm Probability = \frac{ favorable \ outcomes}{total \ outcome}[/tex]
[tex]\rm Probability= \frac{3}{50}[/tex]
Probability = 0.06 or
Probability = 0.06×100 ⇒ 6%
Thus, the probability that there is a left-handed person in a group of 5 randomly selected people is 6%

Step-by-step explanation:
Given
[tex]OZQ = 125[/tex]

Determine PZQ
Since P is an interior of OZQ, we have that:
[tex]OZQ = OZP + PZQ[/tex]

x=-4/9 x=-5/4 NEED HELP GETTING TRINOMIALS FROM SOLUTIONS
The equation 36x^2 + 61x + 20 = 0 solves to x = -4/9 or x = -5/4
==========================================================
Explanation:
x = -4/9 or x = -5/4 .... given solutions
9x = -4 or 4x = -5 .... multiply both sides by denominator
9x+4 = 0 or 4x+5 = 0 .... get everything to one side
(9x+4)(4x+5) = 0 .... zero product property
y(4x+5) = 0 ...... let y = 9x+4
y*4x + y*5 = 0 .... distribute
4xy + 5y = 0
4x( y ) + 5( y ) = 0
4x( 9x+4) + 5( 9x+4 ) = 0 ... plug in y = 9x+4
4x*9x + 4x*4 + 5*9x + 5*4 = 0 ..... distribute
36x^2 + 16x + 45x + 20 = 0
36x^2 + 61x + 20 = 0
-----------------
The equation 36x^2 + 61x + 20 = 0 has the two solutions x = -4/9 and x = -5/4

We need to find the LCD first in order to add the fractions:
7*3 = 21
3*7 = 21
21*1 = 21
So the LCD is 21.
Next, we need to make sure that the fractions have the same denominator in order to add:
-6/7x - 5/21x + 1/3x = -48
-18/21x - 5/21x + 7/21x = -48
-16/21x = -48
Multiply both sides by the reciprocal of -16/21 (21/-16) to get x by itself:
(21/-16)(-16/21)x = -48(21/-16)
x = 63
