Answer:
437,500
Step-by-step explanation:
The percentage value of amount of money spent on radio advertising is given by R = $ 437,500
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let the percentage value of amount of money spent on radio advertising be represented as R
Now , the total amount of revenue money = $ 50,00,000
The percentage of money spent on traditional media = 25 %
So , the amount of money spent on traditional media = percentage of money spent on traditional media x total amount of revenue money
On simplifying , we get
The amount of money spent on traditional media = ( 25/100 ) x 5000000
The amount of money spent on traditional media = $ 12,50,000
Now , the percentage of amount spent on radio advertising = 35 %
So , the amount of money spent on radio advertising = ( 35/100 ) x amount of money spent on traditional media
On simplifying , we get
The amount of money spent on radio advertising = ( 35/100 ) x 12,50,000
The amount of money spent on radio advertising = $ 4,37,500
Hence , the amount of money on radio advertising is $ 4,37,500

A survey of a group of seventh graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. Which compares the modes of the data? The mode for the students is 2 and the mode for the teachers is 4. The mode for the students is 0 and the mode for the teachers is 1. The mode for the students is 4 and the mode for the teachers is 8. The mode for the students is 2 and the mode for the teachers is 1.
The correct option is The mode for the students is 2 and the mode for the teachers is 4.
To determine the mode of a data set, one must identify the number(s) that appear most frequently. In the dot plot for the students, the number of siblings that appears most frequently is 2, as there are 7 dots above the number 2 on the number line. This makes 2 the mode for the students' data.
For the teachers' data, the number of siblings that appears most frequently is 4, with 5 dots above the number 4 on the number line. Therefore, 4 is the mode for the teachers' data.
Comparing the modes of the two data sets, we have:
- Mode for students: 2
- Mode for teachers: 4
The other options provided do not accurately reflect the modes of the data sets based on the given dot plots.
A streaming video company charges $27.50 to set up an account and $12 per month to
enjoy the service. If Landon paid a total price of less than $243.50 for streaming video, how
many months (m) did he use the company's service?
Answer:
18 months
Step-by-step explanation:
27.50+12x=243.50 let x represent amount of months
subtract 27.50 from both sides
12x=216 divide
18 months
The solution is 18 months
The number of months Landon used the streaming service is given by the equation x = 18 months
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Let the number of months be x
A streaming video company charges $27.50 to set up an account and $12 per month to enjoy the service
Let the total cost be represented as y
Landon paid a total price of less than $243.50 ,
So , the value of y = $ 243.50
The inequality equation is 12x + 27.50 < 243.50
12x + 27.50 < 243.50 be equation (1)
On simplifying the equation , we get
Subtracting 27.50 on both sides of the equation , we get
12x < 216
Divide by 12 on both sides of the equation , we get
x < 18
So , the value of x = 18 months
Hence , the number of months is 18 months

2x^2-6x-20=0 value of a
Answer:
a = 2
Step-by-step explanation:
The equation 2x² - 6x - 20 = 0 is in standard form for a quadratic formula.
The general equation for standard form is: y = ax² + bx + c
Sometimes we make "y" => 0 when we are finding the roots (x-intercepts).
Notice "a" is attached to x² in the standard form.
In your question, the number attached to x² is 2.
∴ a = 2
Find the total volume of the following composite figure with
h=4.3
and
r=3.9

Round to the nearest hundredth.
Given:
A composite figure consisting of a cylinder with radius r and height h and a half-sphere with a radius r.
To find:
The total volume of the composite figure.
Solution:
To determine the total volume of the figure, we add the volume of the cylinder and the volume of the half-sphere.
The volume of a cylinder, [tex]V= \pi r^{2} h.[/tex]
The given cylinder has a radius of 3.9 units and a height of 4.3 units. Assume π equals 3.14.
The volume of the cylinder, [tex]V = (3.14)(3.9^{2} )(4.3)= 205.36542[/tex] cubic units.
The volume of a half-sphere, [tex]V= \frac{2}{3} \pi r^{3} .[/tex]
The given half-sphere has a radius of 3.9 units, assume π equals 3.14.
The volume of the half-sphere, [tex]V= \frac{2}{3} (3.14)(3.9^{3} ) = 124.17444[/tex] cubic units.
The total volume of the composite figure [tex]= 205.36542+124.17444=329.53986[/tex] cubic units.
Rounding this off to the nearest hundredth, we get the volume of the cone as 329.54 cubic units.

Which value of b would make x²+bx-30 factorable?
A. -31
B. -17
C. 11
D. 13
Answer:
D. 13
Step-by-step explanation:
well since it's a quadratic equation, it can be written in the form of ax²+bx+c=0. So we have a=1, b=b and c= -30. Also the roots are given by the equation-
x= -b±[tex]\sqrt{b^{2}-4ac}[/tex] /2a. So all I did was put the number from the choices which would satisfy the sqrt part and that turned out to be 13 since [tex]\sqrt{13^{2}-4*1*(-30)[/tex] = [tex]\sqrt{289}[/tex] = 17. So b=13.
An electronics store sends an email survey to all customers who bought tablets. The previous month, 570 people bought tablets. Surveys were sent to 300 of these people, chosen at random, and 138 people responded to the survey. Identify the population and the sample.

The population is 570. The sample is 138.
The population is 570. The sample is 300.
The population is 300. The sample is 138.
The population is 138. The sample is 570.
The population is 138. The sample is 300.
The population is the entire group of customers who bought tablets, totaling 570 people. The sample is the subset of 300 customers who were randomly chosen to receive the survey.
Explanation:In the given scenario, an electronics store has conducted a survey among its customers who purchased tablets. To identify the population and the sample in this context, we look at the definitions of each term. The population is the entire group that is the focus of the study, while the sample is a subset of the population that is surveyed to represent the whole.
The population in this case includes all the customers who bought tablets during the previous month, which totals to 570 people. The sample is the group of customers who were selected to receive the survey. Since surveys were sent to 300 of these customers at random, the sample size is 300.
Therefore, the correct identification is: The population is 570. The sample is 300.
Problem
A knitting pattern for a shawl calls for 8
stitches in the first row. Each row after that
has 2 more stitches than the previous row.
The explicit rule ax = 8 + (k − 1)2 gives the
number of stitches in the nth row row.
Answer:
The n row has [tex]2n+6[/tex] stitches.Step-by-step explanation:
The given expression is
[tex]a_{k}=8+(k-1)2[/tex]
Where [tex]d=2[/tex] and [tex]a_{1}=8[/tex].
The number of stitches in the n row are expressed as
[tex]a_{n} =8+2n-2\\a_{n} =2n+6[/tex]
Therefore, the n row has [tex]2n+6[/tex] stitches.
Notice that the result is an expression, that is beacuse the problem is asking for a general solution, it's asking for the n row, which refers to certain row in general terms.
