The number of children x, belonging to each of eight families registering for swimming was 3,2,6,3,4,2,5,6. Find the mean, x. (Give answer correct to 2 decimal places.)
Answers
The mean number of children per family is 3.88.To find the mean (average) of the number of children in the eight families, we sum up the number of children and divide by the total number of families.
Given the number of children in each family:
3, 2, 6, 3, 4, 2, 5, 6
Step 1: Sum up the number of children:
3 + 2 + 6 + 3 + 4 + 2 + 5 + 6 = 31
Step 2: Divide by the total number of families (which is 8 in this case):
31 / 8 = 3.875
Rounding the mean to two decimal places, we have:
Mean = 3.88
Therefore, the mean number of children per family is 3.88.

Joanna is selling tickets for the school play $he ha$ already $old $35
worth of tickets. $he ha$ seven ticket$ left to sell for $5 per ticket. write
function to describe the total amount of money collected if she sells every single ticket
Answers
Answer:
okay, so given we have that she has already sold $35 worth of tickets. We know that she has seven tickets left to sell, and each is worth $5. So, we would do 7×$5=$35
Next, we would add $35(from the previous money she has made) and $35 (the money she just made from the 7 tickets) and that would equal $70
equation: y=35+7(5)

Answer:
h = 8 inches
Step-by-step explanation:
Since these shapes are similar and one side of the bigger shape is double the other side (44 is the double of 22), to find side h, you have to multiply 4 by 2 (It's the same relationship between the two sides of similar shapes). 4 times 2 is equal to 8, which is your answer.

The measure of the angle SQT will be 70°. The correct option is B.
What is geometry?One of the first areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that In the figure below, angles PQS and TQR are congruent. Angle SQT is 15° larger than angle PQS.
The measure of the angle SQT is,
2∠PQS + ∠SQT = 180
2∠PQS + ∠PQS + 15 = 180
3∠PQS = 165
∠PQS = 55°
The measure of the angle ∠SQT is,
∠SQT = 55 + 15
∠SQT = 70
