Assume that a bacteria population doubles every second. Which of the following tables of data, with X representing time in seconds and y representing the count of bacteria, could represent the bacteria population with respect for time?
(answers in the pic)
Answers
Answer: Table A
Step-by-step explanation:
Because it doubles every second. At 0s, its 3. Then at 1s, it doubles which means 3x2=6, which is in table. then at 2s, that doubles to 6x2=12....and so on

Flora made 3 withdrawals of $65 each from her bank account. What was the overall change in her account?
The total change in her account is $
Answers
Answer:
-$195
Step-by-step explanation:
If she made 3 withdrawals and they are all the same amount then the equation is
65 x 3 or 65+65+65
Which equals 195
Since she is taking money out of her bank account, the total change is negative because she is subtracting it from her current amount

A group of 5 students was asked, "How many hours did you watch television last week?" Here are their responses.
5, 5, 5, 4, 17
Find the mean number of hours for these students.
If necessary, round your answer to the nearest tenth.
Answers
Answer:
7.2 Hours
Step-by-step explanation:
To find the mean which is also known as the average of a set of data, you first have to add all the numbers then divide the sum by the amount of data values. (I remember this by saying the mean teacher averages your grade.)
First, you need to add the numbers. 5+5+5+4+17= 36
Secondly, you need to divide the sum of all the data by the amount of data there is. In this case, there are 5 pieces of data.
Lastly, you divide 36/5
Your final answer should be 7.2
You can check your work by doing 7.2 times 5 which equals 36.

For a tax rate of 8.25%, find the amount of tax that will be paid on an automobile tube-up costing $76. Find the total price of the tune-up with tax.
Answers
Final answer:
To find the tax on a $76 automobile tune-up at 8.25%, convert the tax rate to a decimal (0.0825), multiply it by the tune-up cost ($76), resulting in a tax of $6.27. Adding the tax to the original cost gives a total price of $82.27.
Explanation:
To calculate the amount of tax on an automobile tune-up costing $76 with a tax rate of 8.25%, first, you need to convert the percentage to a decimal. The decimal form of 8.25% is 0.0825. Then multiply the cost of the tune-up by this decimal:
$76 x 0.0825 = $6.27The amount of tax to be paid is $6.27. To find the total price of the tune-up with tax, you simply add the tax amount to the original tune-up cost:
$76 + $6.27 = $82.27Therefore, the total price of the automobile tune-up including tax is $82.27.
Each floor in the old headquarters of Oldham Bank and Trust is 14 feet in
height except the ground floor, which is 24 feet high. There are 5 floors. How
tall is the building?
Answers
How I did it:
Since there are 5 floors (ground floor included) then that means only 1 floor is 24ft so I multiplied 14 by 4 to get 56 then I added 24 to get 80!
To find the total height of the building, we need to calculate the sum of the heights of all the floors.
Height of the ground floor = 24 feet
Height of each floor (except ground floor) = 17 feet
Number of floors (excluding ground floor) = 7 - 1 = 6
Total height of the building = Height of the ground floor + (Height of each floor * Number of floors)
Total height of the building = 24 + (17 * 6)
Total height of the building = 24 + 102
Total height of the building = 126 feet
Therefore, the building is 126 feet tall.
what is the value of y?
Answers
Answer:
60
Step-by-step explanation:
y+y+60=180
2y =120
therefore,y=60
Answer:
C. 60°
Step-by-step explanation:
To answer this problem we must make use of the sum of the internal angles of a triangle.
For any triangle the sum of its internal angles is equal to 180 °.
So we must add all the angles to find the answer:
[tex]y+y+60=180[/tex]
now we can add the two terms 'y'
[tex]2y+60=180[/tex]
and now we clear for 'y':
[tex]2y=180-60\\2y=120\\y=120/2\\y=60[/tex]
The value of y is 60°
Find the domain for f of x equals the quantity x plus 3 divided by quantity x minus 2. (2 points) x ≠ 2 x ≠ -3 x ≠ -3, 2 All real numbers
Answers
Answer:
x different from 2
Step-by-step explanation:
The function is written as the quotient: [tex]\frac{x+3}{x-2}[/tex]
that can give us a real value for any value of x except for x=2 that creates a ZERO in the denominator, making the division undefined.
So the only value for which the function cannot be evaluated is x=2, therefore the function's domain is all the real numbers except for x=2.

The only points that a valid points on the graph of 4y - 6x = 12 are;
Option A; (-4,-3)
Option B; (-1, 1.5)
Option D; (0,3)
We are given the equation;
4y - 6x = 12
Let us make y the subject to get;
4y = 12 + 6x
y = (12 + 6x)/4
y = 3 + ³/₂x
Option A; at (-4, -3), let us put -4 for x to see if we will get y as -3;
y = 3 + ³/₂(-4)
y = 3 - 6
y = -3
Thus, (-4, -3) is a valid point
Option B; at (-1, 1.5)
y = 3 + ³/₂(-1)
y = 3 - 1.5
y = 1.5
Thus, (-1, 1.5) is a valid point
Option C; at (0, -2)
y = 3 + ³/₂(0)
y = 3
Thus, (0, -2) is not a valid point
Option D; at (0, 3)
y = 3 + ³/₂(0)
y = 3
Thus, (0, 3) is a valid point
Option E; At (3, 4)
y = 3 + ³/₂(3)
y = 3 + 4.5
y = 7.5
Thus; (3, 4) is not a valid point
Option F; At (6, 4)
y = 3 + ³/₂(6)
y = 3 + 9
y = 12
Thus, (6, 4) is not a valid point
In conclusion the only valid points are; (-4, -3), (-1, 1.5), (0, 3)

[tex]f(x)=3x-\dfrac{x}{2}\qquad \qquad \text{when}\ x={-3, -2, 4, 6}\\\\\\\\f(-3)=3(-3)-\bigg(\dfrac{-3}{2}\bigg)\\\\\\.\qquad =-9+\dfrac{3}{2}\\\\\\.\quad =\dfrac{-18}{2}+\dfrac{3}{2}\\\\\\.\quad =\large\boxed{-\dfrac{15}{2}}[/tex]

[tex]f(6)=3(6)-\bigg(\dfrac{6}{2}\bigg)\\\\\\.\qquad =18-3\\\\\\.\qquad =\large\boxed{15}[/tex]
The range of the function with the specified domain of {-3, -2, 4, 6} is {-15/2, -5, 10, 15}.
The student asks: if fx=3x-x/2 find the range if the domain is {-3,-2,4,6}. To find the range of the function f(x) = 3x - x/2, we will evaluate the function for each value in the given domain and record the corresponding outputs. This function simplifies to f(x) = (5/2)x when you combine like terms.
For x = -3, f(-3) = (5/2)(-3) = -15/2.
For x = -2, f(-2) = (5/2)(-2) = -10/2 = -5.
For x = 4, f(4) = (5/2)(4) = 20/2 = 10.
For x = 6, f(6) = (5/2)(6) = 30/2 = 15.
On Monday, 449 students went on a trip to the zoo. All 9 buses were filled and 8 students had to travel in cars. How many students were on each bus?
Answers
Answer:
Each bus could pick up 49 students
Step-by-step explanation:
(449-8):9=49
Answer:
Number of students on each bus = 49
Step-by-step explanation:
On Monday, 449 students went on a trip to the zoo. All 9 buses were filled and 8 students had to travel in cars.
Total number of students = 449.
Number of students traveled in car = 8
Number of students traveled in bus = 449 - Number of students traveled in car = 8
Number of students traveled in bus = 449 - 8 = 441
Number of buses = 9
Number of students traveled in bus = Number of buses x number of students on each bus
441 = 9 x number of students on each bus
Number of students on each bus = 49

Answers
Answer:
Option C (The expression 2.35c + 1.75m represents the money earned from selling c bags of cookies and m bags of muffins).
Step-by-step explanation:
It is given that a bag of cookies is priced at $2.35 and a bag of muffin is priced at $1.75. It is also given that the student sells c bags of cookies and m bags of muffins. The total revenue earned by the student by selling c bag of cookies = $2.35 * c bags = $2.35c and the total revenue earned by the student by selling m bag of muffins = $1.75 * m bags = $1.75m. Therefore, the total revenue earned by the student by selling both cookies and muffins = 2.35c + 1.75m. This expression (2.35c + 1.75m) represents the money earned from selling c bags of cookies and m bags of muffins. Therefore, C is the correct choice!!!

What is a linear function?In Mathematics and Geometry, a linear function refers to a type of function whose equation is graphically represented by a straight line on the xy-plane or cartesian coordinate.
Based on the information provided, we can logically deduce the following linear functions;
f(x) = 3x + 1
g(x) = 4x - 5
When x is equal to 3, we have:
f(x) = 3x + 1
f(3) = 3(3) + 1
f(3) = 10
g(x) = 4x - 5
g(3) = 4(3) - 5
g(3) = 7.
Therefore, f(x) is greater.
