6. Open Response While jumping rope, Juan jumped 24 times in 30 seconds. At this rate. how many times will he jump in 50 seconds
levacccp [35]

Juan will jump 40 times in 50 seconds.

The unitary method is a concept wherein a problem is solved first by finding the value of a single unit and then multiplying the single unit value to find the necessary answer.

Here, we are given that

Juan jumps 24 times in 30 seconds

Thus, the number of times he will jump in 1 second is given by-

24/ 30 = 0.8

Thus, he jumps 0.8 times in 1 second

Now, we need to find the number of times he jumps in 50 seconds. We can do so simply by multiplying the number of times he jumps in 1 second by 50.

Thus, number of times he jumps in 50 seconds = 0.8 * 50

= 40

Therefore, Juan jumps 40 times in 50 seconds.

Consider randomly selecting a student at a large university. Let A be the event that the selected student has a Visa card, let B
Tems11 [23]

Answer:

0.75

Step-by-step explanation:

Given,

P(A) = 0.6, P(B) = 0.4, P(C) = 0.2,

P(A ∩ B) = 0.3, P(A ∩ C) = 0.12, P(B ∩ C) = 0.1 and P(A ∩ B ∩ C) = 0.07,

Where,

A = event that the selected student has a Visa card,  

B = event that the selected student has a MasterCard,  

C = event that the selected student has an American Express card,

We know that,

P(A ∪ B ∪ C) = P(A) + P(B) + P(C) - P(A ∩ B) - P(A ∩ C) - P(B ∩ C) + P(A ∩ B ∩ C)

= 0.6 + 0.4 + 0.2 - 0.3 - 0.12 - 0.1 + 0.07

= 0.75

Hence, the probability that the selected student has at least one of the three types of cards is 0.75.
