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]

Solve the following quadratic equation for all values of x in simplest form. 4(3x - 5)^2+5 = 13 (will give brainly)
Answer:
Step-by-step explanation:
4(3x-5)^2+5=13
4(3x-5)^2+5-13=0
As (a-b)^2=a^2-2ab+b^2
4((3x)^2-2(3x)(5)+(5)^2)-8=0
4(9x^2-30x+25)-8=0
36x^2-120x+100-8=0
36x^2-120x+92=0
using the Quadratic Formula where
a = 36, b = -120, and c = 92
x=(−bc± sqrt(b^2-4ac))/2a
x=(-(-120)±sqrt((−120)^2−4(36)(92))/2(36)
=120±sqrt(14400−13248−)/72
=120±sqrt(1152)/72
The discriminant b2−4ac>0
so, there are two real roots.
x=(120±24sqrt(2))/72
x=(120/72)±24sqrt(2)/72
implify fractions and/or signs:
x=5/3±sqrt(2)/3
hich becomes
x=2.13807
x=1.19526
Stacy Arrington is paid $.73 for sewing a
jacket collar, $.86 for a sleeve with cuffs,
and $.94 for a lapel. One week she sewed
318 jacket collars, 112 sleeves with cuffs,
and 37 lapels. Find her gross earnings.
Answer:
Her gross earnings for that week were $ 363.24.
Step-by-step explanation:
Since Stacy Arrington is paid $ 0.73 for sewing a jacket collar, $ 0.86 for a sleeve with cuffs, and $ 0.94 for a lapel, and one week she sewed 318 jacket collars, 112 sleeves with cuffs, and 37 lapels, to find her gross earnings you must perform the following calculations:
(318 x 0.73) + (112 x 0.86) + (37 x 0.94) = X
232.14 + 96.32 + 34.78 = X
363.24 = X
Therefore, her gross earnings for that week were $ 363.24.

Question 3 (Fill-In-The-Blank Worth 3 points) (04.04) Point R is at (2, 1.2) and Point T is at (2, 2.5) on a coordinate grid. The distance between the two points is such as 8.2.) (Input numbers and decimal point only, Answer for Blank 1:
9514 1404 393
Answer:
1.3
Step-by-step explanation:
The two points are on the same vertical line, so the distance between them is the distance between their y-coordinates:
2.5 -1.2 = 1.3
The distance between the two points is 1.3 units.
Which angle is coterminal with a 645° angle?
A. An angle measuring 265°
B. An angle measuring 75°
O C. An angle measuring 285°
D. An angle measuring 345º
Answer:
C
Step-by-step explanation:
Coterminal angles are angles that have a common terminal side.
So, given an angle θ, its coterminal angles will always be ±360°. This can be repeated.
We have a 645° angle.
Therefore, all values of the equation:
[tex]645\pm 360n[/tex]
Where n is an integer is coterminal with our original angle.
Letting n = 1 and using the negative case, we acquire:
[tex]\Rightarrow 645-360=285[/tex]
Therefore, an angle measuring 285° is coterminal with a 645° angle.
None of the other options can be reached by adding/subtracting 360.
Therefore, our answer is C.

A 52-in TV measures 52 inches along its diagonal (corner to corner measure). If that TV is 33.6 inches high, how wide is it?
Step-by-step explanation:
Use Pythagoras' theorem
[tex] {a}^{2} = b {}^{2} + c {}^{2} [/tex]
52² = 33.6² + x²
solve for x
Answer:
1575.04
Step-by-step explanation:
Using Pythagoras theorem,
a^2+b^2=C^2
52^2-33.6^2=1575.04

40% = 20bpm
60% = 30bpm
80% = 40bpm
100% = 50bpm

Answer:
Radius is 9
Formula of a circumference is:
2πr
we can use pie/π as 3.14
3.14 x 2 x 9 (radius) = 56.52
Step-by-step explanation:
If there is a diameter only do half of that and that would be your radius.
Answer:
18π inches (or approximately 56.549 inches)
Step-by-step explanation:
The formula to find circumference is 2πr (or πd). Since we are given the radius (which is half of a circle), we will use 2πr, and the radius (or r) is equal to 9. So you just plug that into the circumference formula, and get:
2*π*9 = 18π
So, the circumference is 18π inches or approximately 56.549 inches (when rounded to the nearest thousandths).

Matteo scored 85 on their first test, 89 on their second test, 85 on their third test, and
89 on their fourth test. Suppose Matteo has one more test in the semester and wants
to finish with a mean score of 88.
What score do they need on their last test to finish with a mean score of 88?
Answer:
He needs 92 on his last test.
Step-by-step explanation:
Mean score:
The mean is the sum of all scores divided by the number of tests.
In this question:
Scores of 85, 89, 85, 89 and x(the last one).
5 tests.
We want a mean of 88. So we find x for a mean of 88.
[tex]\frac{85 + 89 + 85 + 89 + x}{5} = 88[/tex]
[tex]348 + x = 440[/tex]
[tex]x = 440 - 348 = 92[/tex]
He needs 92 on his last test.

You buy tomatoes in 25-pound cases. One batch of Cobb salad requires 1.1 ounces of tomatoes. How many portions can be made with one case? Round down (don’t include partial portions).
Answer:
363 portions can be made with one case.
Step-by-step explanation:
Since I buy tomatoes in 25-pound cases, and one batch of Cobb salad requires 1.1 ounces of tomatoes, to determine how many portions can be made with one case, the following calculations must be performed:
1 pound = 16 ounces
25 pounds = 400 ounces
400 / 1.1 = 363.63
Therefore, 363 portions can be made with one case.
The probability of event A is 0.42, and the probability of event B is 0.39. If A and B are independent events, what is P(A and B)?
Answer:
0.1638
Step-by-step explanation:
P(A and B) or simply the probability of both events happening is the product of their individual probabilities.
P(A and B)= (0.42×0.39)= 0.1638
