In a jail cell, there are 5 Democrats and 6 Republicans. Four of these people will be
chosen for early release. How many 4-person groups are possible?
two because there is 11 people in total and you have two 4 person groups so that would leave 3 people left and you cant make a 4 person group w 3 people
Combination is a way of arranging the required items from a collection of items where the order of selection is not relevant.
If in a jail cell, there are 5 Democrats and 6 Republicans, the possible ways to form a group of 4 is 330.
The number of possible groups is 330.
What is combination?Combination is a way of arranging the required items from a collection of items where the order of selection is not relevant.
It is given as:
[tex]^nC_r = \frac{n!}{r!(n-r)!}[/tex]
We have,
The total number of people:
5 Democrats and 6 Republicans = 5 + 6 = 11.
The number of persons in a group = 4.
The number of groups possible are:
= [tex]^{11}C_4[/tex]
= 11! / 4! ( 11-4)!
= 11! / 4! 7!
= 11 x 10 x 9 x 8 / 4 x 3 x 2
= 330
Thus,
The number of possible groups is 330.

WILL AWARD BRANLIEST !!!Triangle JKL was dilated with the origin as the center of dilation to create triangle J'K'L'. The triangle was dilated using a scale factor of 1/2.
The lengths of the sides of triangle JKL are given.
Enter the lengths of the sides of triangle J'K'L' below.
(Decimal values may be used.)
JK=6 units
J'K'= _units
KL=10.5 units
K'L'= _units
LJ=12 units
L'J'= _ units
The lengths of the new triangle after dilation are; J'K' = 3; K'L' = 5.25 and L'J' = 6
How to carry out dilation of triangles?When it comes to dilation in transformations, it could mean enlarging or reducing the triangle by a scale factor.
Now, we are given the lengths of the original triangle as;
JK = 6 units
KL = 10.5 units
LJ = 12 units
Thus, the dilation by a scale factor of 1/2 indicates a reduction. Thus, the new lengths after dilation are;
J'K' = (1/2) * 6 = 3
K'L' = (1/2) * 10.5 = 5.25
L'J' = (1/2) * 12 = 6

The correct is 122
The required in the diagram of parallel lines is the value of y is 122°.
What are parallel lines?Parallel lines are defined as identical lines with identical orientations, parallel lines never intersect each other but meet at infinity.
Here
Given that DE is parallel to XY, we can conclude that corresponding angles are equal and vertically opposite angles are also equal. Therefore, x is equal to 122° (because vertically opposite angles are equal). Moreover, x and y are equal to 122° (because corresponding angles are equal). Hence, the value of y is also 122°.
Thus, the required in the diagram of parallel lines is the value of y is 122°.

Shelley drove from New Haven, Connecticut, to New York City in 90 minutes. Which equation relates the distance she traveled to her speed?
a.distance = speed + 90
b.distance = speed × 90
c.distance − speed = 90
d.distance × 90 = speed
Answer:
b
Step-by-step explanation:
d = r * t
None of them are really correct, but the closest one is B. Look at the equation. Rate is multiplied by time. The result is distance.
The 90 minutes should be changed to hours. No speedometer on a car is rated in feet per second.
The mayor is interested in finding a 95% confidence interval for the mean number of pounds of trash per person per week that is generated in city. The study included 120 residents whose mean number of pounds of trash generated per person per week was 31.5 pounds and the standard deviation was 7.8 pounds.
Round your answers to two decimal places.
A. The sampling distribution follows a ______ distribution.
B. With 95% confidence the population mean number of pounds per person per week is between_____ and_____ pounds.
C. If many groups of 120 randomly selected people in the city are studied, then a different confidence interval would be produced from each group. About_____ percent of these confidence intervals will contain the true population mean number of pounds of trash generated per person per week and about________ percent will not contain the true population mean number of pounds of trash generated per person per week.
Answer:
A. Normal
B. 30.1, 32.9
C. 95, 5
Step-by-step explanation:
A. The sampling distribution follows a normal distribution
Given that the sample size is large, we have that the sample distribution follows a normal distribution according to the central limit theorem
B. The 95% confidence interval is given as follows;
[tex]CI=\bar{x}\pm z \times \dfrac{s}{\sqrt{n}}[/tex]
The number of residents in the study, n = 120 residents
The sample mean, [tex]\overline x[/tex] = 31.5 pounds
The standard deviation, s = 7.8 pounds
The z-value for 95% confidence level, z = 1.96
Therefore, we get;
C.I. = 31.5 ± 1.96 × 7.8/√(120)
The 95% C.I. ≈ 30.1 ≤ [tex]\overline x[/tex] ≤ 32.9
Therefore, we have that with 95% confidence, the population mean number of pounds per person per week is between 30.1 and 32.9
C. Therefore, according to the central limit theorem, about 95 percent of the groups of 120 will contain the true population mean number of pounds of trash generated per person per week and about 5 percent will not contain the true population mean number of pounds of trash generated per person per week.

A lottery has a grand prize of 25and 1/2 million dollars. There are 5 people who have winning tickets and they share this prize equally. How many millions of dollars does each person get? Express the answer as a mixed number.
Answer:
5 1/10 million dollars
Step-by-step explanation:
25and 1/2 million dollars = 25 1/2 million dollars
= (25*2) + 1 / 2
= 50+1/2
= 51/2
Total prize = 51/2 million dollars
Number of people with winning ticket = 5
How many millions of dollars does each person get?
Amount of prize each person get = Total prize / Number of people with winning ticket
= 51 / 2 ÷ 5
= 51/2 × 1/5
= (51 * 1) / (2 * 5)
= 51/10
= 5 1/10 million dollars
Amount of prize each person get = 5 1/10 million dollars

In how many ways can alice give 12 apples to 3 children if each child must get at least 1 apple
There are 91 ways in which Alice can give 12 apples to 3 children, with each child receiving at least 1 apple using a combination formula.
The question can be solved using a method called "stars and bars".
Now, we need to find the number of ways to arrange 12 stars and 3 bars. The number of ways to arrange 12 stars and 3 bars in the given formula:
Number of ways = (n + k - 1) choose (k - 1)
Where n is the total number of objects = 12
k is the number of groups = 3
Number of ways = (12 + 3 - 1) choose (3 - 1)
Number of ways = 14 choose 2
The combination formula can be used as:
Number of ways = {14!}{(2! [tex]\times[/tex] (14 - 2)!)}
Number of ways = 14! / (2! * 12!)
Number of ways = (14 * 13) / 2
Number of ways = 91
So, there are 91 ways in which Alice can give 12 apples to 3 children, with each child receiving at least 1 apple.

Which expression is a sum of cubes
Answer: what is the rest of the question?
Step-by-step explanation:
The following figures are parallelogram. find X and y
==============================================================
Explanation:
For any parallelogram, the diagonals always cut each other in half.
This means the pieces that are y+5 and 18 cm long are equal
y+5 = 18
y = 18-5
y = 13
And so are the pieces that are x+y and 16 cm long
x+y = 16
x+13 = 16
x = 16-13
x = 3
Side note: the term "bisecting" is often used when saying "cutting in half".
Kylee manages a small theme park and she has been analyzing the attendance data. Kylee finds that the number of visitors exponentially as the tempature increases, and this situation is represented by the function f(x) = 4 ^ x Kylee also finds a linear equation that no deals the number of people who leave the park early depending on the change in temperature , and it is represented by f(x) = - x + 5. The graph of the two functions is below. Find the solution to the two functions and explain what the solution represents.
Answer:
(1 , 4)
Step-by-step explanation:
f(x) = 4^x ,where x is the temperature, and y or f(x) is the number of visitors that come to the park
f(x) = -x +5 , where x is the temperature and, y or f(x) is the number of visitors that leave early
the solution of the system of equations is the point of intersection of the 2 graphs and is (1,4)
when the temperature is 1 will have 4 visitors who will come at the park and also leave early

Answer:
m∠B = 43°
b = 26.1
c = 38.3
Step-by-step explanation:
By applying triangle sum in the given triangle,
47° + 90° + m∠B = 180°
137° + m∠B = 180°
m∠B = 43°
By applying sine ratio to the angle measuring 47°.
sin(47°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{28}{c}[/tex]
c = [tex]\frac{28}{\text{sin}(47^{\circ})}[/tex]
c = 38.28
c ≈ 38.3
By applying cosine rule,
cos(47°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{b}{c}[/tex]
= [tex]\frac{b}{38.3}[/tex]
b = 38.3[cos(47°)]
b = 26.1
Find AC , given that line AD is the perpendicular bisector of BC
Answer:
AC = 29
Step-by-step explanation:
We'll begin by calculating AD. This can be obtained as follow:
AB = 29
BD = 17
AD =?
AB² = BD² + AD²
29² = 17² + AD²
841 = 289 + AD²
Collect like terms
841 – 289 = AD²
552 = AD²
Take the square root of both side
AD = √552
Finally, we shall determine AC. This can be obtained as follow:
DC = BD = 17
AD = √552
AC =.?
AC² = DC² + AD²
AC² = 17² + (√552)²
AC² = 289 + 552
AC² = 841
Take the square root of both side
AC = √841
AC = 29
Read the poem "The Snake" by Emily Dickinson.
A narrow fellow in the grass
Occasionally rides;
You may have met him, — did you not,
His notice sudden is.
The grass divides as with a comb,
A spotted shaft is seen;
And then it closes at your feet
And opens further on.
He likes a boggy acre,
A floor too cool for corn.
Yet when a child, and barefoot,
I more than once, at morn,
Have passed, I thought, a whip-lash
Unbraiding in the sun, —
When, stooping to secure it,
It wrinkled, and was gone.
Several of nature's people
I know, and they know me;
I feel for them a transport
Of cordiality;
But never met this fellow,
Attended or alone,
Without a tighter breathing,
And zero at the bone.
Which statement best describes Dickinson’s use of figurative language in the final stanza?
She uses comparisons to show the speaker’s connection to the snake .
She uses a simile to show that snakes are harmless creatures .

Identify the segments that are parallel, if any, if ∠DCB and ∠CDA are supplementary.
Answer:
C
Step-by-step explanation:
We are given that
[tex]\angle[/tex]DCB and [tex]\angle[/tex]CDA are supplementary.
We have to identify the parallel segments if [tex]\angle[/tex]DCB and [tex]\angle[/tex]CDA are supplementary.
Supplementary angles: If the angles are supplementary then the sum of two angles is 180 degrees.
Therefore,
[tex]\angle DCB+\angle CDA=180^{\circ}[/tex]
Therefore, angle DCB and angle CDA are interior angles .
Because CA is a transversal line and sum of interior angles is 180 degrees.
When the sum of interior angles formed between two lines and on same side of transversal line is 180 degrees. Then the lines are parallel.
Therefore, angle DCB and angle CDA are formed between line AD and BC.
Hence, AD is parallel to BC.
Option C is correct.
