This question is about computing the conditional probability that a painting selected at random is British, given it's from the 20th century. Without specific numbers, the tentative solution is the ratio of the number of British 20th-century paintings to the total number of 20th-century paintings.
The subject here is Probability, a topic within Mathematics. Let us assume without losses in generality that 'T' represents a painting from the 20th century and 'B' represents a British painting. Given 60 paintings, we're selecting one at random. The condition is it's a 20th-century painting ('T') and we need to find the probability that it's also a British painting ('B'). The data given in the question isn't clear enough to give a numerical answer. However, we can give a general solution.
Firstly, we find the number of paintings which are both from 20th century and British. Let's say this number is n. The number of 20th-century paintings would be more than or equal to n. Let's call this N. Therefore, the required probability would be n/N.

Answer:
The values of x and y are x = 25 and y = 18
Step-by-step explanation:
The measure of an arc is equal to the measure of the central angle subtended by it
In circle W
∵ W is the center of the circle
∵ m∠QWS = 90°
∵ ∠QWS is subtended by arc QS
- Use the rule above
∴ m∠QWS = m arc QS
∴ m arc QS = 90°
∵ m arc QS = m arc QR + m arc RS
∵ m arc QR = (x + 11)°
∵ m arc RS = (3y)°
- Add them and equate the answer by 90
∴ (x + 11) + (3y) = 90
- Subtract 11 from both sides
∴ x + 3y = 79 ⇒ (1)
∵ VT passes through W
∴ VT is a diameter in circle W
- Diameter divides the circle into two equal arcs the measure
of its arc is 180° because the measure of the circle is 360°
∴ m arc VQRST is 180°
∵ m arc QRS = 90°
∵ m arc VQRST = m arc VQ + m arc QRS + m arc ST
- Substitute the measures of arc VQRST and QRS
∴ 180 = m arc VQ + 90 + m arc ST
- Subtract 90 from both sides
∴ 90 = m arc VQ + m arc ST
∵ m arc VQ = (y + 7)°
∵ m arc ST = 65°
∴ 90 = (y + 7) + 65
- Add like terms in the right hand side
∴ 90 = y + 72
- Subtract 72 from both sides
∴ 18 = y
Substitute the value of y in equation (1) to find x
∵ x + 3(18) = 79
∴ x + 54 = 79
- Subtract 54 from both sides
∴ x = 25
The values of x and y are x = 25 and y = 18
he has 29 dollars because there is now $25 plus the $4 dollars of debt he paid off.
From -$4 to +$25 is a change (increase) of $29.

B. -3n – 2
C. -4n – 5
D. -5n – 6
Answer:
D) -5n-6
Step-by-step explanation:
-4(n+1)-(n+2)
-4n-4-n-2
-4n-n-4-2
-5n-4-2
-5n-6
Answer:
-(5 n + 6)
Step-by-step explanation:
Simplify the following:
-4 (n + 1) - (n + 2)
-4 (n + 1) = -4 n - 4:
-4 n - 4 - (n + 2)
-(n + 2) = -n - 2:
-4 - 4 n + -n - 2
Grouping like terms, -4 - 4 n - 2 - n = (-4 n - n) + (-4 - 2):
(-4 n - n) + (-4 - 2)
-4 n - n = -5 n:
-5 n + (-4 - 2)
-4 - 2 = -(4 + 2):
-5 n + -(4 + 2)
4 + 2 = 6:
-5 n - 6
Factor -1 out of -5 n - 6:
Answer: -(5 n + 6)
B. 91%
C. 28%
D. 39%
