You are downsizing. Your new residence will have much less closet space than does your current home. You have 12 pair of long pants, 6 pair of short pants and 17 t-shirts. You plan to give some away.
a. In how many ways can a random selection of 9 pair of long pants, 4 pair of short pants and 13 t-shirts be arranged?
b. You randomly select 25 of the items of clothing to give away. What is the probability you select 10 pair of long pants, 3 pair of short pants and 12 t-shirts?
Answer:
a) there are 7,854,000 number of ways the random selections can be arranged
b) the required probability is 0.0445
Step-by-step explanation:
Given that;
you have 12 pair of long pants, 6 pair of short pant and 17 t-shirt which in total;
Total = 12 + 6 + 17 = 35
a) number of ways a random selection of 9 pair of long pants, 4 pair of short pants and 13 t-shirts can be arranged;
⇒ [ 12 × [ 6 × [ 17
9 ] 4 ] 13 ]
= (12! / (9! 3!)) (6! / (4! 2!)) (17! / (13! 4!))
= (220) (15) (2380)
= 7,854,000
Therefore there are 7,854,000 number of ways the random selections can be arranged
b)
Number of ways of selecting 25 item from 35 items;
⇒ [ 35
25 ]
=
(35! / (25! 10!) = 183.579,396
now number of ways to select 10 pair of long pants, 3 pairs of short pantts and 12 t-shirt;
⇒ [ 12 × [ 6 × [ 17
10 ] 3 ] 12 ]
= (12! / (10! 2!)) (6! / (3! 3!)) (17! / (12! 5!))
= (66) (20) (6188)
= 8,168,160
So, Required probability = 8,168,160 / 183,579,396
= 0.0445
So the required probability is 0.0445

O A P(BA) = y
OB. P(
AB) = y
OC. P(BA) = x
OD. P(A and B) = x + y

The condition that must be true about the probabilities is P(A and B) = xy
The probabilities of the events A and B are given as:
P(A) = x
P(B) = y
Given that events A and B are independent events, then we have the following equation
P(A and B) = P(A) * P(B)
The equation becomes
P(A and B) = x * y
P(A and B) = xy
Hence, the condition that must be true is P(A and B) = xy

Answer:
1800000000000000000
The solution is 170°, is the measure of the remaining angle.
What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
given that,
The measures of 5 of the interior angles of a hexagon are: 160°, 90°, 60°, 160°, and 80°.
so, we have,
Sum of all the six interior angles of a hexagon is 720°
now, we get,
The sum of 5 interior angles is = 160°+ 90°+ 60°+ 160°+ 80° degrees
= 550
The missing 6th angle is = 720° - 550degrees
=170
So the remaining angle of hexagon is 170 degrees.
Therefore, the answer is 170°.

The average height of a male ROTC cadet is 70 in. Suppose that 10 percent of the male cadets are taller than 72 in. Assuming that the heights of the cadets are normally distributed, what is the standard deviation
Answer:
1.56
Step-by-step explanation:
Given that :
Average height (μ) = 70 in
10% are taller than 72 in ; the standard deviation Given a normal distribution :
P(x > Z) = 0.10
Using a Z probability calculator, the Z value corresponding to P(x > Z) = 0.10 is 1.282
Z = 1.282
Using the Z relation:
Z = (x - μ) / σ
σ = standard deviation x = 72
1.282 = (72 - 70) / σ
1.282σ = 2
σ = 2 / 1.282
σ = 1.5600624
σ = 1.56
chloe has three dogs. Corky weighs twice as much as muffin.Rufus weighs twice as much as corky. the total weight of the dog is 77 pounds. how much does each dog weigh?
Answer:
Corky = c = 22 pounds
Muffin = m = 11 pounds
Rufus = r = 44 pounds
Step-by-step explanation:
Let the weight of each dog be represented as
Corky = c
Muffin = m
Rufus = r
The total weight of the dog is 77 pounds.
c + m + r = 77
Corky weighs twice as much as muffin.
c = 2m
m = c/2
Rufus weighs twice as much as corky.
r = 2c
Hence
c + c/2 + 2c = 77
3.5c = 77
c = 77/3.5
c = 22 pounds
m = c/2
m = 22/2
m = 11 pounds
r = 2c
r = 2 × 22
r = 44 pounds
Each dog weighs:
Corky = c = 22 pounds
Muffin = m = 11 pounds
Rufus = r = 44 pounds

Expand the left side using the angle sum identity for sine:
sin(x + π/2) = sin(x) cos(π/2) + cos(x) sin(π/2)
cos(π/2) = 0 and sin(π/2) = 1, so the right side reduces to

Patio sets consisting of couches, umbrellas, and a firepit table are sold at a local furniture store, A set with 2 couches, an umbrella and a table are sold for $1875. A set with one couch and a table are sold for $1075. A set with 2 couches and an umbrella are sold for $1275What is the price of the table?
Answer:
[tex]T = 600[/tex]
Step-by-step explanation:
Represent the table with T, couch with C an umbrella with U
We have the following:
[tex]2C + U + T = 1875[/tex]
[tex]C + T = 1075[/tex]
[tex]2C + U = 1275[/tex]
Required
Determine the cost of a table
Make T [tex]the\ subject\[/tex] [tex]in\ the[/tex] first equation
[tex]T = 1875 - (2C + U)[/tex]
In the third equation, we have that: [tex]2C + U = 1275[/tex]
By substituting 1275 for 2C + U
[tex]T = 1875 - (2C + U)[/tex] becomes
[tex]T = 1875 - 1275[/tex]
[tex]T = 600[/tex]
Hence, a table costs $600
19 more than 9 times a number is less than or equal to 163. Which of the following represents the solution set of this problem?
Answer:
x ≤ 6
Step-by-step explanation:
Let the unknown number be x;
9 times the number is expressed as 9x
9 more than 9 times a number is expressed as 9x + 9
9 more than 9 times a number is less than or equal to 163 is then expressed as;
9x + 9≤ 63
≤ is the less than or equal to sign
Find the solution;
9x ≤ 63 - 9
9x≤54
x ≤ 54/9
x≤ 6
Hence the required solution is x ≤ 6

Use the transformations on the function f(x) = x| to select the correct graph of
Answer: A
Step-by-step explanation:
The correct graph to the parent function after the transformation is shown in the picture.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a parent function:
y = |x|
Applying first transformation:
Multiply by 1/3 the graph of the function will stretch
[tex]\rm y = \dfrac{1}{3} |x|[/tex]
Second transformation:
Add 1 to the function, the graph will shift upside by 1 units.

at what x coordinate would a line whose equation is y=2x-3 intersect a perpendicular line whose y intercept is 17
Answer:
Step-by-step explanation:hj
Using linear function concepts, it is found that these lines intersect at x = 8.
The equation of a line is given by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.If two lines are perpendicular, the multiplication of their slopes is -1.Line perpendicular to y = 2x - 3.
Multiplication of the slopes is -1, thus:
[tex]2m = -1[/tex]
[tex]m = -\frac{1}{2}[/tex]
y-intercept of 17 means that b = 17, thus, the equation of the line is:
[tex]y_p = -\frac{1}{2}x + 17[/tex]
They intersect at the value of x for which:
[tex]y = y_p[/tex]
Then
[tex]2x - 3 = -\frac{1}{2}x + 17[/tex]
[tex]2x + \frac{1}{2}x = 20[/tex]
[tex]\frac{5x}{2} = 20[/tex]
[tex]5x = 40[/tex]
[tex]x = \frac{40}{5}[/tex]
