Darius and Matthew have 3 fruit bars.They are both hungry after playing football and decide to split the fruit bar evenly.How much fruit bar will each boy get ?
Answer:
1 1/2 or 1.5
Step-by-step explanation:
If they split 1/2 of the bar with each other
3 bars x 1/2 split bar = 1.5 or 1 1/2 of the shared amount
3 *1/2=1.5 or 1 1/2
f(x)=|3x+5|+6
g(x)=7
find (f+g) (x).
Answer:
[tex](f+g) (x)=\mid 3x+5\mid+13[/tex]
Step-by-step explanation:
Operation of Functions
Given:
[tex]f(x)=\mid 3x+5\mid+6[/tex]
[tex]g(x)=7[/tex]
The sum of (f+g) (x) is:
[tex](f+g) (x)=\mid 3x+5\mid+6+7[/tex]
We cannot operate with the expression inside the absolute bars, thus:
[tex]\boxed{(f+g) (x)=\mid 3x+5\mid+13}[/tex]
You are building a cube shaped box for your turtle to live in. You want to build your box with side lengths of 24 inches. However, when you finish the box, you find out that it has a volume of 27,000 cubic inches. How many more cubic inches is your box than you had planned? How much bigger are your side lengths than you had originally planned?
Answer: The box is 13,176 cubic inches larger than originally planned.
The side lengths turned out to be 6 inches longer than the 24 inches originally planned.
Step-by-step explanation:
To find the intended volume, "cube" 24 (24×24×24)
[tex]24^{3}= 13824[/tex]
To find the difference, subtract 13,824 from 27,000
27000 - 13824 = 13176
To find the actual side lengths of the box that was built take the cube root of 27000.
[tex]\sqrt[3]{27000}=30[/tex]
To find out how much longer, subtract 24 from 30.
30 - 24 = 6

Mr. Witherspoon's fifth grade class was on the
playground. Billy was told to stand still.
Mr. Witherspoon had Rosey stand 10 feet from
Billy. The rest of the class was also told to stand
10 feet from Billy. What shape did the positions of
the class form in relation to Billy?
The location of the circumference of a circle is the set of points that are equidistant from a given point
The shape formed by the rest of the class in relation to Billy is the shape of a circleReason:
Given information;
The distance of Rosey from Billy = 10 feet
The distance of the rest of the class from Bill = 10 feet
Required:
The shape the positions of the class formed in relation to Billy
Solution;
The distance from Billy to each pupil in the class is equal, (10 feet), therefore, Billy is at a central position to the rest of the class
Therefore, the shape that the rest of the class form in relation to Billy is a figure that has Billy as the center or centroid
If the number of pupils in the class is sufficiently, large, the shape formed will be a circle, given that a circle is formed by the set of points that have equal distance from a particular points
Therefore, the shape formed by the rest of the class in relation to Billy is the shape of a circle

A data analytics firm hired by a Republican candidate running for political office wants to test whether its practices were successful in increasing voter turnout among registered Republicans. The firm collected data in a random selection of cities before the candidate ran for office and then after the election. Find the test statistic and the number of degrees of freedom for an appropriate hypothesis test using the data set below. Let the difference d for each city be computed as d=after−before. Assume that the populations are normally distributed. Round the test statistic to three decimal places.
Answer:
The practices were successful in increasing voter turnout among registered Republicans.
Step-by-step explanation:
The missing data is attached below.
The dependent t-test (also known as the paired t-test or paired samples t-test) compares the two means associated groups to conclude if there is a statistically significant difference amid these two means.
In this case a paired t-test is used to determine whether the practices were successful in increasing voter turnout among registered Republicans.
The hypothesis for the test can be defined as follows:
H₀: The practices were not successful in increasing voter turnout among registered Republicans, i.e. d ≤ 0.
Hₐ: The practices were successful in increasing voter turnout among registered Republicans, i.e. d > 0.
Use Excel to perform the paired t-test.
Go to Data → Data Analysis → t-Test: Paired Two Sample for Means
A dialog box will open.
Select the variables.
Set the Hypothesized mean difference as 0.
Press OK.
The output is attached below.
The test statistic value is, t = 5.409.
The degrees of freedom is, df = 9.
The p-value for he one-tailed test is, p-value = 0.00021.
Decision rule:
If the p-value of the test is less than the significance level then the null hypothesis will be rejected.
The p-value of the test is very small for all the commonly used significance level. The null hypothesis will be rejected.
Thus, concluding that the practices were successful in increasing voter turnout among registered Republicans.

What general conclusion would you make about mutually exclusive and independent events given the results of this problem? - Select your answer -
Answer:
Explained below.
Step-by-step explanation:
The complete question is:
Assume that we have two events, A and B, that are mutually exclusive. Assume further that we know P(A) = 0.30 and P(B) =0.40.
What is P(A and B)?
What is P(A | B)?
Is P(A | B) equal to P(A)?
Are events A and B dependent or independent?
A student in statistics argues that the concepts of mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent. Is this statement accurate?
What general conclusion would you make about mutually exclusive and independent events given the results of this problem?
Solution:
The probability of the two events A and B are:
P(A) = 0.30 and P(B) =0.40
(a)
Compute the value of P (A ∩ B) as follows:
[tex]P(A\cap B)=0[/tex]
This is because mutually exclusive events are those events that cannot occur together.
(b)
Compute the value of P (A | B) as follows:
[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}=\frac{0}{0.40}=0[/tex]
Thus, the value of P (A | B) is 0.
(c)
No, P (A | B) is not equal to the P (A).
(d)
As mentioned in part (a), mutually exclusive events are those events which cannot occur together.
That is, [tex]P(A\cap B)=0[/tex].
Events A and B are independent if the chance of their concurrent happening is equivalent to the multiplication of their distinct probabilities.
That is, [tex]P(A\cap B)=P(A)\times P(B)[/tex].
The concepts of mutually exclusive events and independent events are not the same.
(e)
As the it is provided that A and B are mutually exclusive events, we know that [tex]P(A\cap B)=0[/tex].
Now compute the value of [tex]P(A)\times P(B)[/tex] as follows:
[tex]P(A)\times P(B)=0.30\times 0.40=0.12\neq 0[/tex]
Thus, the events A and B are not independent.
Thus, if two events are mutually exclusive events they cannot be independent.
The length of the top of a table is 4 m greater than the width. The area is 60m^2. Find the dimensions of the table
Answer:
Width = 6 m
Length = 10 m
Step-by-step explanation:
Let the width of the table be x meters.
Therefore, length of the table = (x + 4) meters.
[tex]length \times width = Area \\ \\ x(x + 4) = 60 \\ \\ {x}^{2} + 4x - 60 = 0 \\ \\ {x}^{2} + 10x - 6x - 60 = 0 \\ \\ x(x + 10) - 6(x + 10) = 0 \\ \\ (x + 10)(x - 6) = 0 \\ \\ x + 10 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 10 \: \: or \: \: x = 6 \\ \\ \because \: dimensions \: can \: not \: be \: negative \\ \therefore \: x \notin \: 10 \\ \implies \: x = 6 \\ x + 4 = 6 + 4 = 10 \\ width \: of \: table = 6 \: m \\ length \: of \: table = 10 \: m[/tex]
200m - 100m + 48,250 = 50,250 – 150m
200m - 100m + 48,250 = 50,250 - 150m
(Add or subtract common variables)
100m + 48,250 = 50,250 - 150m
(Add 150m to both sides)
250m + 48,250 = 50,250
(Subtract 48,250 to both sides)
250m = 2000
(Divide 250 to both sides to isolate m)
m = 8

What are the solutions to this quadratic equation?
x2+13=8x+37
Answer:
x = 4 + 2 sqrt(10) or x = 4 - 2 sqrt(10)
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 13 = 8 x + 37
Subtract 8 x + 37 from both sides:
x^2 - 8 x - 24 = 0
Add 24 to both sides:
x^2 - 8 x = 24
Add 16 to both sides:
x^2 - 8 x + 16 = 40
Write the left hand side as a square:
(x - 4)^2 = 40
Take the square root of both sides:
x - 4 = 2 sqrt(10) or x - 4 = -2 sqrt(10)
Add 4 to both sides:
x = 4 + 2 sqrt(10) or x - 4 = -2 sqrt(10)
Add 4 to both sides:
Answer: x = 4 + 2 sqrt(10) or x = 4 - 2 sqrt(10)

Here,
Leading coefficient = 3.
Constant term = 4
Factors of 3 are ±1, ±3.
Factors of 4 are ±1, ±2, ±4.
Using rational root theorem, all possible roots of given functions are
[tex]\pm 1,\pm 2,\pm 4,\pm \dfrac{1}{3}, \pm \dfrac{2}{3},\pm \dfrac{4}{3}[/tex]
Clearly, [tex]\dfrac{4}{3},1,2[/tex] are possible roots but [tex]\dfrac{3}{4}[/tex] is not the possible root.
Therefore, the correct option is C.
