The number of cars in 25 families is shown in the table. Calculate the mean number of cars in a family.
No of cars Frequency
1 5
2 10
3 7
4 2
5 1

Answers

Answer 1

Answer:

Mean = 11.8

Step-by-step explanation:

Given the following data;

Total number of cars (n) = 5

Number of cars (x) = 1, 2, 3, 4, 5

Frequency (F) = 5, 10, 7, 2, 1

F(x) = (1*5) + (2*10) + (3*7) + (4*2) + (5*1)

F(x) = 5 + 20 + 21 + 8 + 5

F(x) = 59

To find the mean;

Mean = F(x)/n

Mean = 59/5

Mean = 11.8

Answers

Answer and Step-by-step explanation:

The independent variable is m, and the dependent variable is h.

This is because you can plug in any value for m, making m NOT have to depend on any other value to become m.

With h, it needs the result of m and its other values to become the result of h. H relies/depends on the values in the equation to become a value.

Given g(x)=-2x+2, solve for x when g(x)=8

Answers

Answer:

x=±3. Explanation: g(x)=2x2−10 g(x)=8. ie 2x2−10=8 2x2=18 x2=9 x=±3.

Step-by-step explanation:

x = -3
To solve this, first set -2x + 2 = 8

Now you want to try to get x alone on one side so subtract 2 on both sides
-2x = 6

Finally divide both sides by -2 to find out what x is equal to

x =-3

To check if this is the right answer, plug -3 in for x in the original equation and see if it comes out as 8

-2(-3) + 2 = 8
6 + 2 = 8
8 = 8

Both sides are equal so -3 is the solution

Elis, Raine and Avery buy a boat for $33 000.
Elise pays $12 000, Raine pays $6000 and Avery pays the rest.
Six years later they sell the boat for $25 300.
They share the money in the same ration that they bought the boat.
How much money does Avery lose on the sale of the boat?

Answers

Amount Avery paid: 32,000-12,000-6,000 = 15,000

Divide portion she paid by total cost:

15,000/33,000

Simplify to 15/33

Multiply the amount the boat was sold for by her portion:

25,300 x 15/33 = 11,500

Subtract the amount she got from the amount she paid:

15,000 - 11,500 = 3,500

She lost $3,500

Answer:

yes

Step-by-step explanation:

yes!
