By referring to the table that summarizes service times of dinners at a fast food restaurant, we can see that there are 49 individuals who are included in the summary.
We may calculate the total number of people by simply adding the frequencies:
9 + 20 + 13 + 4 + 3 = 49 people
A measure of an event's frequency is how often it occurs within a specific time frame. For clarity, it is sometimes referred to as temporal frequency and is distinct from angular frequency. The class interval is the distance between the top and lower class bounds of a frequency distribution table. Data are discrete pieces of factual information that are logged and used for analysis. Raw data is the foundation from which statistics are derived. Statistics are the results of data analysis, including its interpretation and presentation. The outcomes of data analysis, including its interpretation and presentation, are statistics. It includes techniques for data collection, evaluation, analysis, and interpretation, is the study and manipulation of data.
Note that the full question is:
Refer to the table summarizing service times (seconds) of dinners at a fast food restaurant. How many individuals are included in the summary? Is it possible to identify the exact values of all of the original service times?
Time (sec) Frequency

Simplify completely the quantity 5 times x to the third power plus 10 times x to the 2nd power plus 15 times x all over 5 times x
Answer:
x²+2x+3
Step-by-step explanation:
We are to simplify the expression;
5x³+10x²+15x/5x
Factor out 5x from the numerator
= 5x(x²+2x+3)/5x
5x will cancel out both at the top and bottom to have;
x²+2x+3
Factorize
x²+2x+3
Hence the simplified form is x²+2x+3

What value of b will make the equation a true statement? Explain how you arrived at your solution. (−34 + 43)+ b = 0
Answer:
b = -9
Step-by-step explanation:
Given the equation (−34 + 43)+ b = 0
We are to find the value of b
First solve for the value in parenthesis
(−34 + 43)+ b = 0
9+b = 0
Subtract 9 from both sides
9+b-9 = 0 - 9
b+0 = -9
b = -9
Hence the value of b will make the equation a true statement is -9

Answer:
3/35, 12/35, 16/35, 4/35
Step-by-step explanation:
The box has a total of 35 squares.
The pink fills 3 squares so the pink section is: 3/35
The dark blue section covers 12 squares
So 12/35 is another fraction.
The light blue area covers 16 squares so another fraction is 16/35
The white covers 4 squares
So the last possible fraction is 4/35.

A rocket is launched from a tower. The height of the rocket, y in feet, is
related to the time after launch, x in seconds, by the given equation. Using
this equation, find the maximum height reached by the rocket, to the nearest
tenth of a foot.
y = -16x2 + 212x + 139
Answer:
y = 841.25 feet
Step-by-step explanation:
Given that,
The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation as follows:
[tex]y = -16x^2 + 212x + 139[/tex] ....(1)
We need to find the maximum height reached by the rocket.
For maximum height, put dy/dx = 0
So,
[tex]\dfrac{d(-16x^2 + 212x + 139)}{dx}=0\\\\-32x+212=0\\\\x=\dfrac{212}{32}\\\\x=6.625\ s[/tex]
Pu x = 6.625 in equation (1).
[tex]y = -16(6.625)^2 + 212(6.625) + 139\\\\y=841.25\ feet[/tex]
So, the maximum height reached by the rocket is equal to 841.25 feet.

Answer:
45000 m
Step-by-step explanation:
Speed = distance / time
10 km/h = distance / 4.5 hours
distance = 10 x 4.5 = 45 km
Kilometre needs to be converted to metres
Ikm = 1000m
45 x 1000 = 45,000m
