What is an estimate?An estimate is a rough calculation that may not be based on real figures or it may be based on rounded-off or appropriated facts and figures.
Estimates enable the decision-maker to make a quick guess or decision that cannot wait for all the facts to be collected.
Thus, the population of interest for the estimate includes members and non-members who have participated.

Let f(t) be outside temperature t hours after 12 PM. Explain the meaning of f (1)>f(7)
If f(t) be the outside temperature t hours after 12 PM, then the meaning of f(1)>f(7) is the outside temperature 1 hours after 12 PM is greater than outside temperature 7 hours after 12 PM.
The function f(t) be the outside temperature t hours after 12 PM
Therefore,
f(1) be the outside temperature 1 hours after 12 PM.
f(7) be the outside temperature 7 hours after 12 PM.
Then,
f(1)>f(7) is the outside temperature 1 hours after 12 PM is greater than outside temperature 7 hours after 12 PM.
Hence, if f(t) be the outside temperature t hours after 12 PM, then the meaning of f(1)>f(7) is the outside temperature 1 hours after 12 PM is greater than outside temperature 7 hours after 12 PM.

At the local dairy farm, Kareem buys a 32-oz container of yogurt for $2.56. Jonah buys a 6-oz container of yogurt for $0.48. Are the cost, y, in dollars and the amount of yogurt, x, proportional?
The quantities Choose... proportional.
The dollar cost y and the amount of yogurt are proportionate
The formula is y = 0.08x
If y fluctuates as directly as x, you may express it as y = kx.
Where k is the proportionality constant.
Determine the value of the proportionality constant. When y = 2.56 and x = 32, you get:
y = kx
k = y/x
k = 2.56/32
k = 0.08
The equation is then: y = 0.08
Check to see if they are directly proportionate. Substitute the amount of yogurt purchased by Jonah. The outcome must be $0,48:
y = 0.08 (6) (6)
y = 0.48
The cost and amount of yogurt are proportionate in a straightforward manner.

The amount in Ebony's bank account B(d) is a function of the number of days d since she opened the account.
The graph segments representing her day-by-day bank balance. Although there are no labeled tick marks on the graph, you can answer the questions by using the additional given information as well as your general knowledge of graphs of functions.
a) Domain of the function 0 ≤ d ≤ 21 (0,21)
Range of the function 0 ≤ B ≤ 400 (0,400)
b) Estimate to the nearest hundreds for B(0) is 200
c) Ebony's bank balance first reached $0 on day 12 can be shown as functional notation as - we can add the number 12 below the first point reaching the horizontal axis.
d) Ebony's bank balance remained $0 from day 12 through day 15. The segment which represents the information is - segment 4.
(a) Domain: the collection of values used as input or arguments for the function.
Range: Either the codomain or the function's image is mentioned.
For three weeks, Ebony's bank account was active (21 days). then the domain is 0 ≤ d ≤ 21 (here 'd' refers to day)
Her highest balance was $400 and her lowest was zero, so the range is 0 ≤ B ≤ 400. (Here, 'B' refers to Balance)
(b) When d = 0, the graph's highest point, which represents her highest balance of $400, is displayed. This means that on the first day, the point will probably only be half as high as the highest point. Therefore, we may calculate the nearest hundred for B(0) is about equal to 0.5 * 400 = 200.
(c) In other words, the line of the function first touches the horizontal axis at d = 12; the balance first reached $0 on day 12. Below the first point that reaches the horizontal axis, we can add the number 12.
(d) From day 12 through day 15, the bank balance stayed at zero dollars; this is shown by the vertical axis of segment 4 of graph 4.
COMPLETE QUESTION:

What is scale factor?The scale factor states the scale by which a figure is bigger or smaller than the original figure.
In other words, scale factor is a ratio between two corresponding sides of similar figures.
Therefore, the actual tower is 1,083 feet tall and 410 feet wide at the base.
The scale model currently has a base that is 0.75 feet wide.
Therefore, the scale factor of the model can be calculated as follows;
The scale factor can be written as a ratio or fraction.
The scale factor of the base to the model is the same with the height of the tower to the model.

Bacteria grow at a rate of 10% per hour in a petri dish.
if there is initially one bacterium and a carrying capacity of 1 million cells, how long (in hours) does it take to reach 500,000 cells?
An initial population of bacteria contain 100000 cell.
The population grow 10% every 1 hours.
This gives us an idea that in another 1 hours we will have 100000 cells organisms.

There are two cars, green car (gc) and a blue car (bc). gc is $15 plus $0.50 per mile driven, bc is $25 plus $0.15 per mile. how many miles do both cars have to drive to cost the same amount?
The number of miles that both the green car and the blue car have to drive to cost the same amount is equal to 28.5 miles.
The number of miles both cars have to travel to cost the same amount can be determined using an algebraic expression. An algebraic expression can be defined as a mathematical equation consisting of both letters and numbers.
As the green car (gc) cost $15 plus $0.50 per mile and the blue car (bc) costs $25 plus $0.15 per mile, an algebraic expression for this problem can be given as follows;
15 + 0.50(x) = 25 + 0.15(x)
Solving for x;
0.50x - 0.15x = 25 - 15
0.35x = 10
x = 10 / 0.35
x = 28.5
Hence, both cars have to drive 28.5 miles to cost the same amount.

What is a consecutive number?
Numbers that follow one another sequentially are known as consecutive numbers. Every time there are two numbers, there is a difference of 1 between them. If n is a number, then examples of consecutive numbers would be n, n+1, and n+2. and 1, 2, 3, 4, 5, and so on.
From the question,
Let's say the smaller integer is x
Then the larger integer will be (x + 1)
According to the question,
4 times the smaller = 4x
3 times the larger = 3(x + 1)
