Answer:
The first option:yellow shirt, white trouseryellow shirt, black trousergreen shirt, white trousergreen shirt, black trouserStep-by-step explanation:
To find the possibilities, you would see that you would have two yellow shirts and two green shirts with different trousers, so you can eliminate the bottom two. And because there will be two of each shirt with defferent trousers, it will be the same for trousers: two of each trouser will be in the possibilities. The only one that fits this description, is the first one.
yellow shirt, white trouser

What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is
53(2x + 2) – 10 ≥ 2x + 2(23x + 2)
Apply the distributive property
106x+106-10≥ 2x + 46x+4
Add the like terms
106x+96≥ 48x+4
Take all common variables on one side
106x-48x≥4-96
106x-48x is 58 and 4 minus 96 is minus 92.
58x≥-92
x≥-92/58
Hence inequality 53(2x + 2) – 10 ≥ 2x + 2(23x + 2) is x≥-92/58.

1. Transplant operations have become routine. One common transplant operation is for kidneys. The most dangerous aspect of the procedure is the possibility that the body may reject the new organ. There are several new drugs available for such circumstances and the earlier the drug is administered, the higher the probability of averting rejection. The New England Journal of Medicine recently reported the development of a new urine test to detect early warning signs that the body is rejecting a transplanted kidney. However, like most other tests, the new test is not perfect. In fact, 20% of patients that experience kidney rejection and 9% of patients that do not experience kidney rejection receive a test result that proves to be incorrect. Physicians know that in about 30% of kidney transplants the body tries to reject the organ. If the new test has a positive result (indicating early warning of rejection), what is the probability that the body is attempting to reject the kidney?
Using conditional probability, it is found that there is a 0.7921 = 79.21% probability that the body is attempting to reject the kidney.
Conditional Probability
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.In this problem:
Event A: Positive test.Event B: Body attempting to reject the kidney.The percentages associated with a positive test are:
80% of 30%(experience kidney rejection).9% of 70%(do not experience kidney rejection).Hence:
[tex]P(A) = 0.8(0.3) + 0.09(0.7) = 0.303[/tex]
The probability of both a positive test and the body attempting to reject the kidney is:
[tex]P(A \cap B) = 0.8(0.3) = 0.24[/tex]
Hence, the conditional probability is:
[tex]P(B|A) = \frac{0.24}{0.303} = 0.7921[/tex]
0.7921 = 79.21% probability that the body is attempting to reject the kidney.

5x + 5 = x + 25 what is x?
Answer:
x = 5
Step-by-step explanation:
5x + 5 = x + 25
subtract 5 from both sides
5x = x + 20
subtract x from both sides
4x = 20
divide both sides by 4
x= 20/4

Answer:
B I think.
Step-by-step explanation:
Answer:
270
Step-by-step explanation:
The figure B is just one 90° rotation away from becoming A, i.e.,
If we rotate B 90° counterclockwise, we get A.
To obtain the same figure after rotating it (counterclockwise or clockwise), the minimum degrees required are 360
So, B becomes A after 90° of rotation, while A becomes A after 360° rotation (in the same direction)
That means,
[tex] \boxed{ \mathsf{Angle \: of \: rotation \: + 90 \: = \: 360}}[/tex]
(angle of rotation is the angle which A turns about in order to line itself with B)

What is the mean? 3 8 7 2 9 6 6 7
Answer:
6
Step-by-step explanation:
To find the mean, you add up all the numbers and divide that by the number of numbers there are.
In this case, the total is [tex]3+8+7+2+9+6+6+7=48[/tex]
There are 8 numbers.
Thus, the mean is 48 ÷ 8 = 6
Hey there!
When you hear/see the word “mean” in mathematics it usually means “average” or “total”.
Formula: sum of the total numbers ÷ total numbers in the data plot
YOUR EQUATION:
3 + 8 + 7 + 2 + 9 + 6 + 6 + 7 ÷ 8
= 11 + 7 + 2 + 9 + 6 + 6 + 7 ÷ 8
= 18 + 2 + 9 + 6 + 6 + 7 ÷ 8
= 20 + 9 + 6 + 6 + 7 ÷ 8
= 29 + 6 + 6 + 7 ÷ 8
= 35 + 6 + 7 ÷ 8
= 41 + 7 ÷ 8
= 48 ÷ 8
= 6
Therefore, your mean is: 6

Is X=7 an oblique Line?
Answer:
no
Step-by-step explanation:
Generally oblique is used to describe the relationship between 2 lines, but only 1 is given. Oblique means slanted to a degree other than a multiple of 90°, usually in reference to the other line.
x = 7 is a vertical line, and that is exactly 90°, -90°, or even 270° or -270° depending on how you look at it, so it is not oblique on its own.
Answer:
x = 7 is not an oblique line.
Step-by-step explanation:
x = 7 is the standard equation for a vertical line, x = a, with an undefined slope. Vertical lines do not have horizontal change. Hence, its line will not be oblique (or slanted).
The equations in slope-intercept form (y = mx + b), standard form (Ax + By = C), and point-slope form [y - y₁ = m(x - x₁)] will most likely represent an oblique line, as long as its slope (m) ≠ 0. A line with a zero slope is a horizontal line (which is also not an oblique line).
Therefore, x = 7 is not an oblique line, but rather a vertical line.
