Answer:

Step-by-step explanation:

The description is too ambiguous to reconstruct the diagram. You need to post the actual diagram.

That diagram is just one way to view division by a fraction. An easier way: DIVIDING by a fraction is the same as MULTIPLYING by the upside-down fraction. For example,

(1/2) ÷ (1/4) = (1/2) × (4/1) = 2

That doesn’t help you answer this particular question, though.

Suppose that 35 people are divided in a random manner into two teams in such a way that one team contains 10 people and the othe
Effectus [21]

Answer:

0.5798 or 57.98%

Step-by-step explanation:

The total number of ways to form the two teams is the combination of choosing 10 people out of 35 (₃₅C₁₀). The number of possibilities that A and B are both on the 10-people team is given by the combination of choosing 8 people (since two are fixed) out of 33 (₃₃C₈).The number of possibilities that A and B are both on the 25-people team is given by the combination of choosing 10 people out of 33 (₃₃C₈).

Therefore, the probability that two particular people A and B will be on the same team is:

P = \frac{_{33}C_8+_{33}C_{10}}{_{35}C_{10}} \\\\P=\frac{\frac{33!}{(33-8)!8!}+\frac{33!}{(33-10)!10!} }{\frac{35!}{(35-10)!10!}} \\\\P=\frac{69}{119} = 0.5798

The probability is 0.5798 or 57.98%.

A school administrator believes that the mean class gpas for a given course are higher than the preferred mean of 2.75 at a sign
Svetach [21]

The mean GPA is greater than 2.75.

<h3>What is GPA?</h3>
  • A grade point average is a figure that represents the average of the final grades obtained in courses over time.
  • A student's grade point average, sometimes known as a GPA, is computed by adding all accumulated final grades and dividing the total by the number of grades granted.

To find the GPA:

  • GPA is calculated and could be utilized by the college to tell choices, which include the subsequent educational progression.
  • Divide the total range of grade factors earned with the aid of the total number of letter-graded units undertaken.
  • Mean GPA = total/50
  • = 2.75.

Therefore, the mean GPA is greater than 2.75.

Gabrielle is 3 times older than mikhail. the sum of their ages is 80. how old is mikhail
skelet666 [1.2K]
The sum of their ages equals 80.
Gabrielle is 3 times older than Mikhail

Two numbers that have a sum of 80, with one number being 3 times the other are:
Gabrielle’s age: 60
Mikhail’s age: 20

60 + 20 = 80
20 x 3 = 60


Mikhail is 20 years old.
