Answer: havles and half have a difference of the amount of halves
Step-by-step explanation: such as one half is just 1 havles, but 2 halves you have 2 a halfs.
Two different drugs, X and Y, are currently in use to treat a certain condition. About 7 percent of the people using either drug experience side effects. A random sample of 75 people using drug X and a random sample of 150 people using drug Y are selected. The proportion of people in each sample who experience side effects is recorded.
Therefore ,option C is correct since the percentage sample would need to be higher than 100 to produce a significant result.
What is a percentage?A percentage is a subdivision by 100, also referred to as percent. A percentage, which is defined as "per 100," denotes a component of an overall amount. For instance, 45% represents the number 45 out of 100. Calculating a percentage is the process of finding the proportion of a whole given terms of 100. There are choices for fraction computation and using online calculators.
Given:
A random selection of 75 drug users of drug X and just a random selection of 150 drug users of drug Y are chosen,
Most statisticians agree that you need a 100 sample size to get any kind of statistically meaningful findings. You should absolutely poll each and every person in a population of less than 100.
The representative sample for medication X is therefore insufficient.
Therefore ,option C is correct since the sample would need to be higher than 100 to produce a significant result.

A regular octagon $ABCDEFGH$ has an area of one square unit. What is the area of the rectangle $ABEF$
The area of the rectangle ABEF = 2sa = 2ss/(2*tan(180/8)) = s^2/(tan(180/8)).
What is an octagon?
An octagon is a polygon with eight straight sides and eight angles. It is a closed two-dimensional shape with eight sides of equal length. A regular octagon is an octagon in which all sides and angles are equal.
When it comes to the area of a regular octagon, the area of a regular polygon can be calculated using the formula
A = (ns^2)/(4tan(180/n)) where A is the area, n is the number of sides and s is the length of each side.
In case of a regular octagon, the area of an octagon is (8s^2)/(4tan(180/8))
A rectangle ABEF is made up of two congruent sides with the length of the side of the octagon, and two congruent sides with the length of the apothem of the octagon.
An apothem of a regular polygon is the distance from the center of the polygon to the midpoint of any side. The apothem of a regular octagon can be calculated by using the formula
a = s/(2*tan(180/8)) where a is the apothem and s is the side of the octagon.
Hence, the area of the rectangle ABEF = 2sa = 2ss/(2*tan(180/8)) = s^2/(tan(180/8)).

Belinda is thinking about buying a house for $179,000. The table below shows the projected value of two different houses for three years:
Answer:
A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Part A :
If a function is linear, then the function values have equal differences.
If a function is exponential, the function values have equal ratios.
For car 1 :
36450 / 40,500 = 9/10
32805 / 36450 = 9/10
Values of car have equal ratios.
This is exponential function.
For car 2 :
39000 - 42000 = -3000
36000 - 39000 = -3000
Values of car have equal differences
This is linear function.
Part B :
The initial value of car is 45,000.
For car 1 :
f(1) = 40,500, f(2) = 36,450, ............
For car 2 :
f(1) = 42,000, f(2) = 39,000, ..........
Part C :
For car 1 :
f(13) = = 11438.396
For car 2 :
f(13) = = 6000
There is a significant difference in the values of the car after 13 years. The value of the car 1 is greater.
Hence the value of the car 1 is described by an exponential function and that of car 2 by linear function. The value of car 1 is greater after 13 years.

A tone i launched into the air from a height of 240 feet. The height,h , of the tone, in feet, econd after launch i given by the formula h = - 16t^2 32t40. After how long will the tone hit the ground?
When the tone's height, h, equals 0, we can determine when the tone will fall to the ground. The equation that expresses the height of the tone as a function of time is as follows:
h = -16t^2 + 32t + 40
where t is the number of seconds since the tone was launched, and h is the tone's height in feet.
We can set the formula equal to 0 because we are aware that h = 0 when the tone strikes the ground:
-16t^2 + 32t + 40 = 0
Here is the quadratic formula:
t = (-b ± √(b^2 - 4ac)) / 2a
where a = -16, b = 32, and c = 40.
With these values entered into the formula, we obtain:
t = (-32 ± √(32^2 - 4(-16)(40))) / 2(-16)
t = (-32 ± √(1024 + 2560)) / (-32)
t = (-32 ± √(3584)) / (-32)
t = (-32 ± 64) / (-32)
t = (32) / (-32) or (-96) / (-32)
t = -1 or 3
The duration of the tone before it reaches the ground is -1 or 3 seconds.
However, as there is no such thing as a negative amount of time, it takes 3 seconds for the tone to reach the earth.

After 4 years of recycling and re-using, approximately average one-half of the original 350,000 cans produced by the soft drink company would still be in use.
1. 350,000 cans produced in 1 year
2. 50% of cans recycled each year
3. 50% of 350,000 cans = 175,000 cans
4. After 4 years, 175,000 cans still in use.
Each year, it is predicted that about half of all aluminum cans will be recycled. This means that if a soft drink company produces 350,000 cans one year, then after four years, approximately one-half of the original cans produced would still be in use. This can be calculated by taking the initial number of cans produced (350,000), multiplying it by fifty percent (50%), and then multiplying that number by four (4). The final result is that after four years of recycling and re-using, approximately 175,000 cans would still be in use.

what is the total number of points of intersection of the graphs of the equations y 5 ex and xy 5 20 ?
A. The total number of points of intersection of the graphs of the equations y = 5e^x and xy = 20 is two.
To find the points of intersection, we must solve the two equations for x and y.
For the first equation, y = 5e^x, we can solve for x by taking the natural logarithm of both sides and getting x = ln(y/5).
For the second equation, xy = 20, we can solve for y by dividing both sides by x and getting y = 20/x.
We can then substitute the expression for x in terms of y into the expression for y in terms of x and solve for y to get y = 20/(ln(y/5)). This is a nonlinear equation that must be solved numerically.
By using numerical methods, we can solve the equation and find the two points of intersection, which are (x, y) = (3.68, 4.64) and (x, y) = (0.87, 22.95).

a) Détermine le solde du compte au bout de 3 ans
b) Quel est le total de l'intérêt accumulé ?
a) Pour déterminer le solde du compte au bout de 3 ans, nous devons utiliser la formule de l'annuité de fin de période. Il y a un total de 3 ans x 12 mois/an = 36 mois de capitalisation. Le taux d'intérêt par mois est de 6%/12 = 0.005. La somme déposée chaque mois est de 100 $. En utilisant la formule, nous pouvons calculer le solde final:
M = (R[(1 + i)^n −1])/i
M = (100 [(1 + 0.005)^36 −1])/0.005 = $51,664.23
b) Pour calculer le total de l'intérêt accumulé, nous pouvons soustraire le montant total des dépôts (100 $ x 36 mois = $3,600) au solde final du compte.
Intérêt accumulé = Solde final du compte - Montant total des dépôts
Intérêt accumulé = $51,664.23 - $3,600 = $48,064.23
En résumé, le solde final du compte après 3 ans est de 51,664.23 $ et l'intérêt accumulé est de 48,064.23 $.

How much did one tree and one bush cost?Although I don't have subtotals for the bushes and trees, I could try to add the bushes and trees to get 19 bushes and 6 trees, but this wouldn't help me at all.
So I'll choose two variables ("b" for the quantity of bushes and "t" for the quantity of trees) and construct an equational structure:
13b + 4t = 487 is the first order.
second order: 6b plus 2t equals 232.
When I divide the second row by -2, I obtain:
13b + 4t = 487
-12b – 4t = –464
Therefore, b must equal 23.
Using back-solving, I discover that t = 47.
Naturally, the task did not require the values of the two variables.
The answer, when translated back into English, is:
Each tree costs $47 and each bush is $23.
