Answer:

1.4%

Step-by-step explanation:

You can only include 7 and 8 in the answer because it didn't include 6 in the question. add the frequency for both of those sizes (14) and divide by the total (1000) to get the probability. multiply by 100 to get answer as a percent. 1.4%

Answer:

Step-by-step explanation:

We are given the results of survey of one thousand families to determine the distribution of families by their size.

We are to find the probability (in percent) that a given family has more than 6 people.

Frequency of people with more than 6 people = 10 + 4 = 14

Total frequency = 1000

P (families with more than 6 people) = (14 / 1000) × 100 = 1.4% ≈ 1%

Solve the system of equations. y = 4x + 6 3x + y = 41

Mama L [17]

→ Chapter : Linear Equation of Two Variables ←
≡ We know that:
↔ y = 4x + 6

⇔ 3x + y = 41
↔ y = 41 - 3x

≡ Solution:
⇔ First, find the value of x:
⇒ y = y
⇒ 4x + 6 = 41 - 3x
⇒ 4x + 3x = 41 - 6
⇒ 7x = 35
⇒ x = 5

⇔ Then, find the value of y:
⇒ y = 4x + 6
⇒ y = 4(5) + 6
⇒ y = 20 + 6
⇒ y = 26

∴ So, the solution of that equation is (5, 26)
