What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
A small town has 2,500 residents.
In a random sample of 125 residents, 2 have the flu.
i.e. in 2500 residents have flu = 2500*2/125
=5000/125
=40
Hence, 40 is the number of residents of the town who have the flu.

A king size candy bars costs $1 with each candy bar having 1,472 calories. If you bought 7 candy bars and took 8 days eating them (eating the same amount each day) how many calories would you consume a day?
Answer: your mom gay ;)
Step-by-step explanation:
4,500 calories a day
If you ate the same amount each day, that means you would eat 3 a day, since 6 divided by 2 is 3.
Find how many calories you would eat each day by multiplying 3 by 1,500
3(1,500)
= 4500
A model rocket is launched with an initial upward velocity of 62/ms. The rocket's height h (in meters) after t seconds is given by the following.
h=62t-5t^2
Find all values of t for which the rocket's height is 29 meters.
Round your answer(s) to the nearest hundredth.
9514 1404 393
Answer:
t = 0.49, 11.91
Step-by-step explanation:
A graphing calculator can show you the answers quickly. The times are 0.49 seconds and 11.91 seconds.
__
We can write the equation as ...
h = 29
62t -5t^2 = 29 . . . . . substitute for h
-5(t^2 -12.4t) = 29
-5(t^2 -12.4t +6.2^2) = 29 -5(6.2^2) . . . . complete the square
-5(t -6.2)^2 = -163.2 . . . . . simplify
t -6.2 = ±√(-163.2/-5) = ±√32.64 . . . . divide by -5, take the square root
t = 6.2 ±5.71
t = 0.49, 11.91
The rocket has a height of 29 meters at t=0.49 seconds and t=11.91 seconds.
For the equation, complete the given ordered pairs.
3x-y=4
{0,_} [1,_} {_,4}
Hi
3x-y = 4
so y = 4-3x = -3x +4
now you just have to remplace X by the first number given.
for 0 you have : y = -3*0 +4 = 4
so it's 0; 4

Write an expression that represents the height of a tree that begins at 5 feet and increases by 4 feet
per year. Let y represent the number of years.
An event manager recorded the number of people in different age groups that attended a music concert.
A histogram titled Concert Audience is shown. The horizontal axis is labeled Age Group in years with bins 18 to 24, 25 to 31, 32 to 38, and 39 to 45. The vertical axis labeled Number of People with values from 0 to 120 at intervals of 20. The first bin goes to 20, the second goes to 40, the third goes to 120, and the last goes to 80.
Which data table accurately represents the data in the histogram? (5 points)
Age Group Number of People
18−24 80
25−31 120
32−38 40

The data table that accurately represents the histogram is the last table since the information matches the one in the histogram.
How to identify the correct data table?Understand the histogram and in this case the number of people in each category. For example, from 18 to 24, there are 20 people.Compare the information to the data tablesChoose the one that matches.What is the correct data table?The correct option is the last one or:
Age Group Number of People
18−24 2025−31 4032−38 12039−45 80Because only in this one does the data match the one in the histogram.

total events revenue from sale of
the tickets was $250,000. Find
each
th number of tickets sold
for each
stand
Answer:
Step-by-step explanation:
Okay, so this is impossible to tell the amount of spaces, but let's say it was 4000 for VIP and 4000 for Popular Stands. Multiply $30 by 4000, and you get $120k Earnings. To check your answer, Divide 120,000 by 4000, and you get $30 for each stand.
Now, let's move on with the VIP stands. A VIP Stand costs $50, so 4,000 x $50 = $200k earnings. To check your answer, divide 200,000 by 4000, and you get $50 for each VIP Stand.
If you need to find each variant, go by 1k seat increments, i.e. 1000 and 7000, 2000 and 6000, etc.

Makers of a new pain-relieving medication claim that it relieves chronic pain faster than the current top-selling pain reliever on the market. A
double-blind experiment was conducted in which 10 people who experience chronic pain were randomly selected to take either the new or the
current medication. Each of the 10 people recorded the time, in minutes, from taking the medication until pain relief. After an appropriate time
period, each of the 10 people took the other medication and recorded the time from taking the medication until pain relief. The medication each
person took first was randomly determined, and because both medications look the same, the people in the study did not know which medication
was taken first. The table below shows summary statistics for the results.

A circular hot spring has a diameter of 106 meters. Over time, the diameter of the spring decreases by 2 meters. By how many square meters does the area of the hot spring decrease? Use 3.14 for
Answer:
The area decreased by 329.7 square meters.
Step-by-step explanation:
For a circle of diameter D, the area is:
A = pi*(D/2)^2
with pi = 3.14
In this case, we start with a circle of D = 106m
Then the initial area is:
A = 3.14*(106m/2)^2 = 8,820.26 m^2
After, the diameter is decreased by two meters, then the new diameter is:
D' = 106m - 2m = 104m
And the new area will be:
A' = 3.14*(104m/2)^2 = 8,490.56 m^2
The change in the area is A - A' = 8,820.26 m^2 - 8,490.56 m^2 = 329.7m^2
The area decreased by 329.7 square meters.
