Assuming that she does not replace the first card, you have to combine the two probabilities of drawing a numeral, then drawing a numeral again. The probability of drawing a numeral is \frac{9}{35} or 25.71%. The 35 is a count of all the cards in the bag. The probability that she draws a numeral the second time without replacing the first one is now: \frac{8}{34} or 23.53%. Multiplying these together gets you: \frac{36}{595} or 6.05%.

The probability is 34% because 9/26=.34615384615. The first 2 numbers makes the percentage

In the diagram below, what is the relationship between the number of triangles and the perimeter?
Eduardwww [97]

The perimeter "P" is equal to the length of the base of one triangle multiplied by the "n" number of triangles in the figure plus two times the length of another side. The equation for the perimeter is P = 5n + 14.

We are given triangles. The triangles are arranged in a certain pattern. The length of the base of each triangle is equal to 5 units. The length of the other two sides is 7 units each. We conclude that all the triangles are isosceles. We need to find the relationship between the number of triangles and the perimeter of the figure. Let the perimeter of the figure having "n" number of triangles be represented by the variable "P".

P(1) = 14 + 5(1)

P(2) = 14 + 5(2)

P(3) = 14 + 5(3)

We can see and continue the pattern. The relationship between the perimeter and the number of triangles is given below.

P(n) = 14 + 5n
