Answer:
Explanation:
Work out the equation:
1st row is 11 seat and the seat after it will be 6 more and 6 more after the second row and so on. This can be written:
6(x - 1) + 11 =
Where x determine the number of row.
Ex: if x = 1 thus, 6(0) + 11 = 11 seat which is the first row.
Find the number of seats in row 18:
6(18 - 1) + 11
6(17) + 11
= 102 + 11
= 113 seats

Conditional statement.</h2>
A mathematical statement of the form 'If A Then B' is a conditional statement.
<h3>
Explanation:</h3>
A conditional statement in geometry is an if-then statement consisting of a hypothesis and a dependent conclusion. The structure of a conditional statement is:
<em>If (......hypothesis......), then (......conclusion......)</em>
If hypothesis = A and conclusion = B, the mathematical expression for a conditional statement is: <u>A → B</u> and it is read as <u>If A then B.</u>
A conditional statement is always true unless the hypothesis is true and the conclusion is false.
A conditional statement can be written in form of its converse, inverse and contrapositive.
<u>Example of a conditional statement is</u>
A = I am 18 years old
B = I am an adult
A conditional statement is of the form (<u>A → B</u>) "If A then B"; therefore
If I am 18 years old, then I am an adult.
Answer:
A) 10-14
B) 45
C) 6.7%
Step-by-step explanation:
A) The interval that contain the most values can be gotten by looking at the histogram and selecting the interval with the highest frequency. Hence the interval 10-14 contains the most values because it has a frequency of 20.
B)The total number of swimmers is gotten by summing all the frequency of each individual lap. Hence:
Total swimmers on team = 10 + 12 + 20 + 0 + 3 = 45 swimmers
C) The percentage of swimmers who swam more than 14 laps = (number of swimmers that swam more than 14 laps/total swimmers) * 100%
The percentage of swimmers who swam more than 14 laps = [(0 + 3)/45] * 100% = (3/45) * 100% = 6.7%
