Suppose that a large family has 14 children, including two sets of identical triplets, three sets of identical twins, and two individual children. How many ways are there to seat these children in a row of chairs if the identical triplets or twins cannot be distinguished from one another
Answer:
First, assume that we have 14 seats in a row.
Let's count the total number of combinations assuming that the 14 kids are differentiable.
In the first seat, we can sit only one child, the number of options is (14)
In the second seat, we can sit another child, in this case, the number of options is 13, because one child is already seated.
For the third seat, we will have 12 options.
for the fourth seat we will have 11 options, and so on.
The total number of permutations is equal to the product between the numbers of options for each case.
Then the total number of permutations is:
P = 14*13*12*11*...*3*2*1 = 14!
Now, we need to discount the permutations of the two sets of identical triplets:
a triplet has 3 elements, then the permutations of each set of triplets is:
p = 3*2*1 = 3!
Then if we discount two sets of triplets, we need to divide by:
d = 2*(3!)
We also have 3 sets of twins, the permutations for each set of twins is:
p = 2*1 = 2!
Then if we discount the 3 sets of twins, we need to by:
q = 3*(2!)
Then the total number of different combinations will be:
[tex]P = \frac{14!}{2*(3!)*3*(2!)} = 1,210,809,600[/tex]

The dot plot shows the favorite sport to play according to some middle school students chosen at random.
Which statement is true according to the information in the dot pot?
Answer choices
A. Exactly 2/5 of the students chose basketball, golf, and track as their favorite sport to play.
B. Exactly 15% of the students chose baseball as their favorite sport to play.
C. Less than 1/5 of the students chose soccer and hockey as their favorite sport to play.
D. More than 25% of the students chose football and tennis as their favorite sport to play
PLEASE ANSWER THE QUESTION. IF YOU DONT KNOW YOU DONT KNOW
Answer:
D. More than 25% of the students chose football and tennis as their favorite sport to play
Step-by-step explanation:
From the dot plot :
Sport __Number of students
Hockey = 4
Track = 2
Tennis = 3
Basketball = 12
Soccer = 6
Football = 10
Golf = 5
Baseball = 8
Total = (4+2+3+12+6+10+5+8) = 50
Students of basketball, golf and track = (12 + 5 + 2) = 19 ; 19 /50 =
Percentage that chose base ball = 8 /50 *100 = 16%
(soccer + hockey) = (6+4) = 10/50 = 1/5
Football + tennis = (10 + 3) = 13
13/50 = 0.26 * 100% = 26% (True)

LCM of (2^3×3×5) and (3×5) is
Answer:
120
Step-by-step explanation:
LCM of (2^3×3×5) and (3×5) is
The LCM of the expression will be the product of all the factors that are in both expressions
(2^3×3×5) = 2 * 2 * 2 * 3 * 5
(3 * 5) = 3 * 5
since 3 * 5 is common to both factors, we will not have to repeat it twice to get our LCM again. Hence the LCM is expressed as;
LCM = 2 * 2 * 2 * 3 * 5
LCM = 8 * 3 *5
LCM = 24 * 5
LCM = 120
Hence the required LCM is 120
In planning a Thanksgiving vacation, you want to rent a car for a week and travel the Pacific Highway from San Francisco to San Diego. You want to return to San Francisco via Las Vegas, Death Valley, and Yosemite National Park. This trip covers approximately 1,500 miles. You plan to return the car with a full tank of gasoline. You are considering two options advertised by Hertz:
Toyota Camry, 40 mpg highway, costs $448.27 plus taxes and fees, totaling $533.65.
Toyota Prius Hybrid, 49 mpg highway, costs $610.58 plus taxes and fees, totaling $772.88.
In both cases, you must purchase gasoline, which costs $4.00 per gallon in California.
Camry: Total gasoline cost is?
Answer:
The gas cost for the Camry will be $ 150.
Step-by-step explanation:
Since in planning a Thanksgiving vacation, you want to rent a car for a week and travel the Pacific Highway from San Francisco to San Diego, and you want to return to San Francisco via Las Vegas, Death Valley, and Yosemite National Park, and this trip covers approximately 1,500 miles, and you plan to return the car with a full tank of gasoline and are considering two options advertised by Hertz:
Toyota Camry, 40 mpg highway, costs $ 448.27 plus taxes and fees, totaling $ 533.65.
Toyota Prius Hybrid, 49 mpg highway, costs $ 610.58 plus taxes and fees, totaling $ 772.88.
In both cases, you must purchase gasoline, which costs $ 4.00 per gallon in California.
To determine the total cost of gasoline for the Camry, the following calculation must be performed:
(1,500 / 40) x 4 = X
37.5 x 4 = X
150 = X
Therefore, the gas cost for the Camry will be $ 150.
What is the equation of a line that contains the point (6,-4) and has a slope of 3/4?
A. y-4 = 3/4 (x-6) B. y+ 4 = 3/4 (x-6) C. y- 6 = 3/4 (x-4) D. y-6 = 3/4 (x+4)
Answer:
B. y+ 4 = 3/4 (x-6)
Step-by-step explanation:
Given:
m = 3/4
Slope-intercept:
y - y1 = m(x - x1)
y + 4 = 3/4(x - 6)

8. Which of the following correctly multiplies f(x) x g(x) if f(x) = 3x-1 and g(x) = 2x + 1?
A) f(x) x g(x) = 6x2 + x + 1
B) f(x) x g(x) = 5x
C) f(x) x g(x) = 6x2 + x-1
D) f(x) x g(x) = 5x2 + x-1
Answer:
C) f(x) x g(x) = 6x2 + x-1
Step-by-step explanation:
Multiplication of functions:
Two multiply two polynomial functions, we apply the distributive property(multiply each two terms and add).
In this question, we have that:
[tex]f(x) = 3x - 1, g(x) = 2x + 1[/tex]
The multiplication is:
[tex]f(x) \times g(x) = (3x - 1)(2x+1) = 3x*2x + 3x*1 -1*2x -1*1 = 6x^2 + 3x - 2x - 1 = 6x^2 + x - 1[/tex]
The correct answer is given by option C.

c = 2.2m is the answer.
Step-by-step explanation:
a = 1m
b = 2m
c = ?
According to the Pythagorean theorem,
a² + b² = c²
1² + 2² = c²
1 + 4 = c²
c² = 5
c = 2.2m
∴ the slide is 2.2m long.
I NEED HELP UNDER 5 MINUTES BEST ANSWER GETS BAINLESS hits 96 must play 3 minutes of commercials for every 30 minutes of music played. how many minutes of commercials must be played for 210 minutes of music?
Answer:
21
Step-by-step explanation:
so the relationship is that the music is ten times the commercials so, divide 210 by 30 and times that number by 3 210/30= 7, 7'3=21
Answer:
21 minutes of commercials
Step-by-step explanation:
If Hits 96 must play 3 minutes of commercials for every 30 minutes of music played, than the ratio of minutes of commercials to minutes of music is 3:30=1:10.
If 210 minutes of music is played, we can model the situation with the equation [tex]\frac{1}{10} =\frac{x}{210}[/tex]
We can use cross multiply to simplify the equation to [tex]10x=210[/tex]
Dividing each side by 10, we get [tex]x=21[/tex]
So, if 210 minutes of music is played, 21 minutes of commercials is played.

Answer:
no, b does not equal 5 in that equation
Step-by-step explanation:
if you solve for x, this is how it would look:
65/b + 8 x 4 = 20
65/b + 32 = 20
65/b = 20 - 32
65/b = -12
65 = -12b
-12b = 65
b = -65/12 (or -5 5/12)

37.7Expression represents five less a third of a number?
Answer:
[tex] \frac {1}{3}x - 5 [/tex]
Step-by-step explanation:
Let the unknown number be x.
Translating the word problem into an algebraic expression, we have;
[tex] \frac {1}{3}x - 5 [/tex]
Or
[tex] \frac {x}{3} - 5 [/tex]
Simplifying further, we have;
[tex] \frac {x}{3} = 5 [/tex]
Cross-multiplying, we have;
x = 15
Therefore, the above algebraic expression is five less a third of a number.
Solve for the missing side. Round to the nearest tenth.
