There are 200 students in an eleventh-grade high school class. There are 40 students in the soccer team and 50 students in the b

asketball team. Out of these students, there are 10 who play on both teams.
Let A be the event that a randomly selected student plays soccer and B be the event that the student plays basketball. Based on this information, answer the following questions.
What is P(A) the probability that the student plays soccer?
What is P(B) the probability that the student plays basketball?
What is P(A and B) the probability that the student plays soccer and basketball?
What is P(A | B) the conditional probability that the student plays soccer given that he or she plays basketball?

Is P(A | B)=P(A)? Are events A and B independent?
Choose all answers that apply:

(Choice A)
Yes, P(A | B)=P(A)

(Choice B)
No, P(A | B)≠P(A)

(Choice C)
Yes, events A and B independent events.

(Choice D)
No, events A and B are not independent events.

The parallelogram below is being covered with carpet. The carpet is priced at $2.80 per square meter. How much will it cost to c
cestrela7 [59]

Answer:

It will cost $79.38 to carpet the shape

Explanation:

Find the diagram of the parallelogram attached

Area of a parallelogram = Base * Height

Given

Base = 8.1m

Height = 3.5m

Area of the parallelogram = 8.1*3.5

Area of a parallelogram  = 28.35m²

Since 1m² = $2.80

28.35m² = x

Cross multiply

x = 28.35 * 2.80

Hence it will cost $79.38 to carpet the shape

Given a graph for the transformation of f(x) in the format g(x) = f(kx), determine the k value.
AlexFokin [52]

Answer: C

1/4

Step-by-step explanation:

Given a graph for the transformation of f(x) in the format g(x) = f(kx),

This means that for every value of x, f(x) will take the value it would have had at kx, that is, the graph of f(x) is stretched by a factor of 1/k in the direction of positive x-direction.

Therefore, the value of k will be 1/4.

Sergio039 [100]
S + 2l = 1372
s + l =858

s + 2l = 1372
-s - l =. - 858

l= 514 grams a large bottle

s + 514= 858

s = 344 grams a small bottle
