If the length of one base of a trapezoid is 44, the median is 36, and the other base is 2x + 10, find x.
Answer:
9
Step-by-step explanation:
The median is the average of the base lengths. Where "b" is the length of the other base, we have ...
36 = (44 +b)/2
b = 72 -44 = 28
We are told this is the same as 2x+10, so we have ...
28 = 2x +10
18 = 2x . . . . . subtract 10
9 = x . . . . . . . divide by 2
The value of x is 9.

Barnes and Nobles buys a book for $14.25. They markup the price of the book by 35%.
Answer:
$19.24
Step-by-step explanation:
Take 14.25 times 1.35.
The markup rate will be 35% when the cost of the book is $14.25 and sells for $19.237.
What is the markup rate?The markup rate is computed by dividing a unit's gross profit (its sales price less its cost to create or buy for resale) by its cost.
Barnes and Noble buy a book for $14.25. They mark up the price of the book by 35%.
As per the question, we have
cost = $14.25
markup rate = 35% = 0.35
Let's x represent markup for the book,
markup rate = markup/sale price × 100%
35% = x / $14.25
0.35 = x / $14.25
x = $14.25 × 0.35
Apply the multiplication operation, and we get
x = 4.9875
So sale price = markup + cost
So sale price = $4.9875 + $14.25
So sale price = $19.237
Thus, the markup rate will be 35% when the cost of the book is $14.25 and sells for $19.237.

Determine the y-intercept of the function.
x = 4y - 6
Answer:
y = 3/2
Step-by-step explanation:
Answer:
x=4y-6
Geometric figure: Straight Line
Slope = 0.500/2.000 = 0.250
x-intercept = -6/1 = -6.00000
y-intercept = 6/4 = 3/2 = 1.50000
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
x-(4*y-6)=0
Step by step solution :
Step 1 :
Equation of a Straight Line
1.1 Solve x-4y+6 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line x-4y+6 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 3/2 so this line "cuts" the y axis at y= 1.50000
y-intercept = 6/4 = 3/2 = 1.50000
Calculate the X-Intercept :
When y = 0 the value of x is -6/1 Our line therefore "cuts" the x axis at x=-6.00000
x-intercept = -6/1 = -6.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.500 and for x=2.000, the value of y is 2.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 2.000 - 1.500 = 0.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.500/2.000 = 0.250
Geometric figure: Straight Line
Slope = 0.500/2.000 = 0.250
x-intercept = -6/1 = -6.00000
y-intercept = 6/4 = 3/2 = 1.50000

The answer to the volume of a sphere/hemisphere should only be written as a(n)
Answer:
Cubic unit.Step-by-step explanation:
The answer to the volume of a sphere/hemisphere should only be written a cubic unit, because volumes depends on three coordinates to be defined, width, lenght and height, where each coordinates is a length itselft, which multiplied give a cubic length unit, due to the power properties.
For example, imagine that you have all three dimensions in meters, then the product would be [tex]m \times m \times m=m^{3}[/tex].
Therefore, the answer that completes the statment is cubic unit. A volume should be always written in cubic units.
Answer:
The answer to the volume of a sphere/hemisphere should only be written as a function of the radius.
Step-by-step explanation:
An hemisphere is half of a sphere. Its volume can be determined by dividing the volume of a given sphere by 2. The volume is the maximum space or capacity that a 3 dimensional object occupies.
volume of a sphere = [tex]\frac{4}{3}[/tex] [tex]\pi[/tex] [tex]r^{3}[/tex]
volume of an hemisphere = [tex]\frac{2}{3}[/tex] [tex]\pi[/tex] [tex]r^{3}[/tex]
In both cases, the volume is dependent on the value of radius.
The answer to the volume of a sphere/hemisphere should only be written as a function of the radius. Volume is measured in cubic units.
What’s the answer to this question ?
Answer:
the correct choice is marked
Step-by-step explanation:
The zero-crossings at -3 and +3 tell you that one of the factors is the difference of squares:
(x +3)(x -3) = x^2 -9
The zero crossing at -1 tells you that x+1 is a factor.
So, the polynomial factors as ...
f(x) = (x^2 -9)(x +1)
Multiplying this out, we get ...
f(x) = x^2(x +1) -9(x +1)
f(x) = x^3 +x^2 -9x -9 . . . . . . matches the first choice

Two expressions are below.
M = 4(2x + 6)
N = 8x + 10
Part A:
Apply the distributive property to write an expression that is equivalent to expression M.
Part B:
Explain whether or not expressions M and N are equivalent for any value of x.
Label your answers to both parts of the problem in the response box.
Answer:
Part A: 8x + 24
Part B: Expressions M and N are not equivalent for any value of x because if you do 8x + 24 = 8x + 10, the 8x will cancel out from both sides and you are left with 24 = 10, which is not true, and therefore has no solution.
Step-by-step explanation:
For Part A, to apply the Distributive Property, you multiple the 4 with both terms in the parentheses. So, you do 4(2x) + 4(6). This expression is equal to 8x + 24.

Vocabulary Drag the words to show how theoretical probability and experimental probability differ. Each word may be used only once.
Theoretical
Experimental
probability is based on expected or calculated results.
probability is based on the actual recorded results of an
experiment.
Answer:
Theoretical --- probability is based on expected or calculated results.
Experimental --- probability is based on the actual recorded results of an experiment.
Step-by-step explanation:
Theoretical assumptions are those hypotheses not proven to be real, whose probabilities of materializing depend on the future confirmation of the premises established. Thus, these theories are established based on different experiences and previous situations, or based on data still not scientifically proven.
Instead, the experimental results are those that have already been confirmed based on tests, tests and experiments that affirm or deny the previously established theories.

The driveway in front of the brown house is 35 feet long and the driveway in front of the red house is 7 yards, 9 feet long. Which house has the long driveway and by how much? *
Brown house driveway; larger by 30 feet
Red house driveway; larger by 7 feet
Brown house driveway; larger by 5 feet
They are both equal.
Answer:
Brown house driveway; larger by 5 feet
Step-by-step explanation:
Lets convert yds to ft
We know 3 ft = 1yd
3*7 = 21
so 7yds = 21 ft
Add the 9 ft
7yds 9ft = 21+9 = 30 ft
The house with the 35 ft driveway is longer by (35-30) or 5 ft

Jose invests $4000 in an investment account paying 8% annually for 12 years. Suppose the interest was compounded quarterly instead of annually.
How much would the future value of the investment increase?
Enter your answer as a dollar amount, such as: $302.26
Answer:
$275.6
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.
In this question:
[tex]P = 4000, r = 0.08, t = 12[/tex]
Anually:
[tex]n = 1[/tex]
Then
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(12) = 4000(1 + \frac{0.08}{1})^{12}[/tex]
[tex]A(12) = 10072.68[/tex]
Quarterly:
[tex]n = 4[/tex]
Then
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(12) = 4000(1 + \frac{0.08}{2})^{12*4}[/tex]
[tex]A(12) = 10348.28[/tex]
How much would the future value of the investment increase?
10348.28 - 10072.68 = 275.6
The future value of the investment would increase by $275.6.

Step-by-step explanation:
Suppose we want to explore if there is significant evidence of difference among Category A, B, and C in the proportion of Level 1 for certain characteristic.
A B C Total
Level 1 50 90 225 365
Level 2 150 210 275 635
Total 200 300 500 1000
At significant level 0.05, test the equality of proportion of Level 1 for category A, B and C. If needed, perform the Marascuilo procedure for pairwise comparisons. Show your work.
Answer:
Kindly check explanation (since we need to show how the work is done) but what can be noticed is that there is a proportional difference between the 3.
Step-by-step explanation:
Know that Vo :ht = 1//3, where t = 1,2,3.
(1). The expected values for levels A, B and C = 0.33 which is a total of 100%.
The observed values = 50, 90, and 225 with a total of 365.
The expected values = 121.67 for the three categories which gives us a total of 365.
For the three categories, the differences between the observed values and the expected values are -71.67, -31.67 and 103.33.
(2). Thus, the value for the test statistics is = (observed values - expected values)^2/ expected values.
So, for the three categories (A,B and C) we have; 42.217, 8.244 and 87.754. The total = 138.215.
Therefore the critical value = 5.991.
(3). We have to reject the null hypothesis Because 138.215 is greater than 5.991.
(4). For Marascuilo, we have;
Proportion
Group 1 - group 2 = 0.05(absolute difference) and 0.099050609( critical range) which is insignificant.
Group 1 - group 3 = 0.2( absolute difference) and 0.092643256(critical range) which is significant.
Group 2 - group 3 = 0.15(absolute difference) and 0.084615602(critical range) which is also significant.
