What number is 24% of 80

The probability will be "0.20".

According to the question,

• The sum of all the areas = 60

then,

Therefore,

→

Final answer:

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.

Explanation:

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.

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)
