Answer:
d = 261 miles
Step-by-step explanation:
Given that,
The distances (in miles) driven in the past week by each of a company's sales representatives are listed below.
78 126 238 284 310 356
We need to find the median of the distances.
There are 6 data. If n is even,
[tex]median =\dfrac{\dfrac{n}{2}^{th}+(\dfrac{n}{2}+1)^{th}}{2}\\\\median =\dfrac{\dfrac{6}{2}^{th}+(\dfrac{6}{2}+1)^{th}}{2}\\\\=\dfrac{3^{rd}+4^{th}}{2}\\\\=\dfrac{238+284}{2}\\\\=261\ mi[/tex]
So, the median distance is 261 miles.
Which values of xwould make a polynomial equal to zero if the factors of the
polynomial were (x+6) and (x+9)?
A. 6 and -9
B. -6 and 9
C. -6 and -9
D. 6 and 9
9514 1404 393
Answer:
C. -6 and -9
Step-by-step explanation:
For the polynomial to be zero, one or more of the factors must be zero. For the factors to be zero, we require ...
x +6 = 0
x = -6 . . . . . . subtract 6 from both sides of the equation
and likewise, ...
x +9 = 0
x = -9 . . . . . . subtract 9 from both sides of the equation
x = -6 or -9 will make the polynomial zero.

Step-by-step explanation:
Jackson is making brownies. He uses the following ingredients.
Ingredients Amount for 1
Batch of Brownies
Flour 3 cups
Sugar 2 cups
Butter 1/3 cup
Cocoa Powder 1/4 cup
Jackson has 1 cup of butter. If he wants to use all the butter, how many batches of brownies can he make?
Part A
Which equation can you use to solve the problem?
A. 1 ÷ 3 = 3
B. 1 ÷ 1/3 = 3
C. 1 × 1/3 = 1/3
D. 1 + 1/3 = 1/3
Part B
Jackson used all the butter to make the brownies.
If each brownie is 1/9 of a batch, how many brownies did he make?
Enter your answer in the box.
brownies
Answer:
Part A = B. 1 ÷ 1/3 = 3
Part B = 27 brownies
Step-by-step explanation:
Part A
From the ingredients given in above question:
1/3 cup of butter = 1 batch of brownies
Hence: 1 cup of butter = x
Cross Multiply
1/3 cup of butter × x = 1 cup of butter × 1 batch of brownies
x = 1 cup of butter × 1 batch of brownies/1/3 cup of butter
x = 1 batch of brownies ÷ 1/3
x = 1 batch of brownies × 3/1
x = 3 batches of brownies
Hence, the number brownies Jackson can make with 1 cup of butter Is 3 batches of brownies
Therefore, the equation you can use to solve the problem is Option B. 1 ÷ 1/3 = 3
Part B
If each brownie is 1/9 of a batch, how many brownies did he make?
We know from Part A that Jackson made 3 batches of brownies hence:
1/9 of a batch of brownies = 1 brownie
3 batches of brownies = x
Cross Multiply
1/9 of a batch of brownies × x = 1 brownie × 3 batches of brownies
x = 1 brownie × 3 batches of brownies/ 1/9 of a batch of brownies
x =( 3 ÷ 1/9) brownies
x = ( 3 × 9/1) brownies
x = 27 brownies
Therefore, the number of brownies he made was 27 brownies.

Let's call a song danceable if it has a danceability of at least 0.7. What is the probability that an individual song has a danceability of at least 0.7
Answer:
32.54%
Step-by-step explanation:
To determine the probability that an individual song has a danceability of at least 0.7
Applying the excel formula below
=COUNTIF ( I2:I4771,">0.7") / ROWS( I2:I4771)
Hence ; The probability of an individual song having a danceability of at least 0.7 = 32,54%
A complex excavation has a depth of 6 inches and can be broken into three shapes with areas of 100, 226, and 300 square feet. The total volume of the excavation is
Answer:
Step-by-step explanation:
What are the units of the shapes? I will assume inches, but if that is not so leave a note.
Begin by adding the surface area of the 3 shapes.
V = 6*(100 + 226 + 300)
Now add them before multiplying by 6
V = 6* ( 626)
Multiply by 6
V = 3756 cubic inches.
Answer:
V = 3756 units^3
Step-by-step explanation:
Area 1 is 100units^2 multiply by 6
= 100 x 6 is 600units^3
Area 2 is 226units^2 think 5 x 225 = 1125 + 225 + 6
= 226 x 6 = 1356units^2
Area 3 is 300
= 300 x 6 = 1800 think 3x6x100
Total volume is 600+1356+1800 = 3756 units^3

a salesperson earns 5.5% commission on $21000 with a retainer of $23. what is the total earned?
Answer: 1178
Step-by-step explanation:
You can make 5.5% 0.055
Multiply 0.055 by $21000
0.055 x $21000 = 1155
Then you have to add 23
1155+23=1178

A health care organization, StarCare, wants to implement a program to increase use of diabetes care services. In the past StarCare has billed insurance companies $350 per group session on cardiac care, a similar service, and thus plans to bill $350 for the diabetes group sessions. Operational expenses for the diabetes care services will be $1,000. Because StarCare is concerned with quality of services, it plans to have a consistent group size of 20 participants. However, the number of group facilitators will vary based on the number of diabetes care group participants. For every participant, it costs StarCare $300 in facilitator salary and other expenses. StarCare will only do one session if it is profitable. Based on this information, what are the (a) fixed costs for the proposed diabetes care program and the (b) the total variable costs for 20 participants?
Answer:
a) The fixed cost is $1350.
b) Total variable cost is $6000.
Step-by-step explanation:
a) The fixed cost = Operational cost + Insurance company bill.
= $ 1000 + 350 = $1350.
b) Variable cost:-
The number of facilitators = 20.
The salary for each facilitator = $300.
Total variable cost = $300 x 20 = $6000.

You and a friend are driving go-karts on two different tracks. As you drive on a straight section heading east, your friend passes above you on a straight section heading south. Are these sections of the two tracks???
Yes, these sections of the two tracks, because cross each other while moving in perpendicular directions.
Given that,
You and a friend are driving go-karts on two different tracks. As you drive on a straight section heading east, your friend passes above you on a straight section heading south.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
As given in the question they both move in a different direction that is perpendicular to each other which implies one of them pass over the other by any means such as a subway or bridge.
Thus, Yes, these sections of the two tracks, because cross each other while moving in perpendicular directions.

After the first exam in a statistics course, the professor surveyed 14 randomly-selected students to determine the relation between the amount of time they spent studying for the exam and exam score. She found that a linear relation exists between the two variables. The least-squares regression line that describes this relation is: y=6.3333x+53.0298.
Required:
a. Predict the exam score of a student who studies 2 hours.
b. Interpret the slope.
c. What is the mean score of students who did not study?
d. A student who studies 5 hours for the exam scored 81 on the exam. Is this student's exam score above or below average among all students who studies 5 hours?
Solution :
Given :
Equation :
y = 6.3333 x + 53.0298
Here, x = number of hours studied
y = the exam score
a). To predict the exam score, we have to replace x in the least square regression line by 2 :
y = 6.3333 x + 53.0298
y = 6.3333 (2) + 53.0298
= 65.6964
Thus he predicted exam score is 65.6964
b). The slope is the co-efficient of x in the least squares regression line :
Slope = 6.3333
The slope represents the average increase in y as x increases by 1.
The exam score increases on average by 6.3333 points per hour studied.
c). The mean score of the [tex]\text{ students who did not study}[/tex] (studied 0 hours) is obtained by replacing x in the least squares regression line by 0 :
y = 6.3333 x + 53.0298
y = 6.3333 (0) + 53.0298
= 53.0298
d). To predict the exam score of a student who studied 5 hours, we replace x in the least squares regression line by 2 :
y = 6.3333 x + 53.0298
y = 6.3333 (5) + 53.0298
y = 84.6963
Thus the average exam score of a student who studied 5 hours is 84.6963
Since the actual exam score 81 is less than the average exam score of 84.6963 the student's exam score is below the average.

The circumference of a circle is 9.22cm
Find the length of the diameter.
Give your answer rounded to 2 DP.
de
cm
Answer:
Step-by-step explanation:
circumference of a circle = 2πr
9.22 cm = 2*3.14*r
9.22 cm = 6.28*r
9.22 cm /6.28 = r
1.4681 = r
diameter of a circle = 2*r
=2*1.4681
=2.9362
=2.9 cm
Answer:
The Length of diameter of circle is 2.93cm.
Step-by-step explanation:
Given :-Circumference of circle = 9.22 cmTo Find : -Length of diameter, dFormula Used :-Circumference of circle = π × dwhere , d is the length of diameterSolution:-Using formula
Circumference of circle = π × d
substitute the values
9.22 cm = π × d
Using value of π = 3.14
9.22 cm = 3.14 × d
divide each side by 3.14
9.22 cm / 3.14 = 3.14 × d /3.14
2.93 cm = d
Hence, The Length of diameter of circle is 2.93cm.
