a)

Mean = 17 + 19 + 25 / 3
Mean = 61/3
Mean = 20.3

b)

Mean = 38 + 36 + 34 + 32 / 4
Mean = 140/4
Mean = 35

c)

Mean = 8.3 + 2.6 + 7.4 + 1.8 + 9.5 / 5
Mean = 29.6/5
Mean = 5.92

d)

Mean = -5 + 2 - 1 + 0 - 9 + 4 / 6
Mean = -9/6
Mean = -1.5

Monica’s school band held a car wash to raise money for a trip to a parade in New York City. After washing 125 cars, they made $

nikklg [1K]

The system of linear equations represents the situation is;

x + y = 125

x + y = 1255x + 8y = 775

<h3>Simultaneous equation</h3>

Simultaneous equation is an equation in two unknown values are being solved for at the same time.

let

number of quick washes = x
number of premium washes = y

x + y = 125

5x + 8y = 775

From equation (1)

x = 125 - y

5x + 8y = 775

5(125 - y) + 8y = 775

625 - 5y + 8y = 775

- 5y + 8y = 775 - 625

3y = 150

y = 150/3

y = 50

Substitute y = 50 into

x + y = 125

x + 50 = 125

x = 125 - 50

x = 75

Therefore, the number of quick washes and premium washes Monica’s school band had is 75 and 50 respectively.

Find the common difference for the sequence shown

Mrrafil [7]

Answer:

The common difference is 1/16

Step-by-step explanation:

The given sequence is linear. This means that it is an arithmetic sequence. In an arithmetic sequence, each successive term differ by a common difference. The given set of numbers is

1/4, 5/16, 3/8,....

The second term - the first term = the third term - the second term

The common difference would be

5/16 - 1/4 = 3/8 - 5/16 = 1/16
