Answer:

A. 19°

Step-by-step explanation:

To find the average of something, you add every number in the sequence and then divide it by how many numbers there are.

23 + 17 + 26 + 5 + 33 + 11 = 115

115 / 6 = 19.16666666666667

Round it down and your answer will be 19°.

sweet-ann [11.9K]

Answer:

22.67 containers.

Step-by-step explanation:

The number of cars washed is the average by the total hours worked:

$C_{total}=\bar xt,\bar x=8.5,t=8\\\\C_{total}=8.5\times 8=68$

Given that each car uses 1/3 tin of wax, the total containers is calculated as:

$Containers=\bar x_c n,n=68,\bar x_c=\frac{1}{3}\\\\=\frac{1}{3}\times 68\\\\=22.67$

Hence, the car wash uses 22.67 containers of wax per day.

Andru [333]

Answer:

90/361

Step-by-step explanation:

1. Find the probability to grab a red and blue sock.

p(red sock) = 10/19

p(blue sock) = 9/19

2. Multiply the two probabilities.

10 x 9 = 90

19 x 19 = 361

3. Simplify only if it is possible to do so.

4. The answer is 90/361.
