growth model for a certain country
2004 Population(millions) 42.4
Projected 2022 Population
(millions)____
Projected Growth Rate, k 0.0145
The projected 2022 population is ____ million
Answer:
2,1
Step-by-step explanation:
Answer: ≈ 55.045
Step-by-step explanation:
The formula is A=Pe^rt
A = (?) projected population
P = 42.4 (current population)
r = 0.0145 (growth rate)
t = 18 (difference between years: 2022 - 2004)
A = 42.4e^0.0145(18)
A = 42.4e^0.261
A = 42.4(1.298227665)
A ≈ 55.045

Swedish researchers concluded that viewing and discussing art soothes the soul and helps relieve medical conditions such as high blood pressure and constipation. This conclusion was based on a study in which 10 elderly women gathered once a week to discuss different works of art. The study also included a control group of 10 elderly women who met once a week to discuss their hobbies and interests. At the end of 4 months, the art discussion group was found to have a more positive attitude, to have lower blood pressure, and to use fewer laxatives than the control group.(a) Why would it be important to determine if the researchers assigned the women participating in the study at random to one of the two groups?i) Assigning women at random ensures that the two groups are comparable.ii) Assigning women at random satisfies the conditions of a single-blind experiment. iii) Assigning women at random is not important for the study and can be neglected.(b) Explain why you think that the researchers included a control group in this study.i) A control group is absolutely unnecessary hereii) A control group allows the experiment to be conducted once more if the first attempt failed. iii) A control group is used to increase the size of the sampleiv) A control group provides a baseline for comparisons to determine treatment effects.
Answer:
i) Assigning women at random ensures that the two groups are comparable.
iv) A control group provides a baseline for comparisons to determine treatment effects.
Step-by-step explanation:
(a)
It is pertinent that there two comparable groups. In light of the fact that it will help in making better decisions since there will be some people who have blood pressure as a result of uncontrolled physical characteristics such as anger, positive attitude, lower blood pressure. etc Thus, there is a need to consider two equivalent groups.
(b)
A control group is used as a benchmark for determining the cause and effect of a treatment on a given experimental group. This may be in regard to the social aspect of meeting other individuals involved that make up the physical changes.

Chuck-A-Luck: To win any money, at least two of your dice must show the same number. What's the likelihood of winning anything after one roll?
Answer:
0.2778
Step-by-step explanation:
Each sides in a fair die has a probability of = 1/6
The probability of getting the same number on both dice is 6 from 36 outcomes, that is;
= 6/36 = 1/6
the probability of get same number on both dice after one roll = 1/6
therefore = 1/6 x 1/6 = 1/36 = 0.2778

Derek unpacked 126 kilograms of grapefruits and lemons. The grapefruits came in 10-kilogram bags and the lemons came in 8-kilogram bags. In all, Derek unpacked 13 bags of fruit. How many bags of grapefruits and bags of lemons did he unpack?
Answer:
11 bags of grapefruits; 2 bags of lemons
Step-by-step explanation:
Create a system of equations.
Let x be the number of grapefruit bags. Let y be the number of lemon bags.
x + y = 13
10x + 8y = 126
Rearrange the first equation to solve for x:
x = 13 - y
Substitute x in for x in the second equation:
10(13 - y) + 8y = 126
130 - 10y + 8y = 126
-2y = -4
y = 2
Plug y back into the first equation to solve for x.
x = 13 - 2
x = 11

An elevator is traveling underground at a constant rate. The equation y= -2x - 10 can be used to represent this situation, where y is the position of the elevator underground in feet and x is the number of seconds the elevator has been traveling Which statement best describes the position of the elevator, given this equation?
O From a starting position of 2 feet underground, the elevator is descending 10 feet per second
O From a starting position of 10 feet underground, the elevator is descending 2 feet per second
O From a starting position of 2 feet underground, the elevator is ascending 10 feet per second
O From a starting position of 10 feet underground, the elevator is ascending 2 feet per second
4 is correct
reason is because the number next to x is the constant number and the end number is where you started

A car is traveling at a rate of 48 miles per hour. If the car continues to travel at this same rate, how many hours will it take the car to travel 612 miles?
Answer:
12.75
Step-by-step explanation:
If you make a proportion: 48/1=612/x
1(612)= 612
612/48
12.75 hours
At a speed of 48 miles per hour, the car will take approximately 12.75 hours to go 612 miles.
What is the distance?A mathematical number known as distance measures "how much ground an object has traveled" while moving. Distance is defined as the product of speed and time.
A car is traveling at a rate of 48 miles per hour.
To determine the number of hours it will take the car to travel 612 miles at a rate of 48 miles per hour, you can divide the distance traveled by the rate at which the car is traveling:
⇒ distance ÷ rate
⇒ 612 miles / 48 miles/hour
Apply the division operation, and we get
⇒ 12.75 hours
Therefore, it will take the car about 12.75 hours to travel 612 miles at a rate of 48 miles per hour.

Answer:
g(x) = (x-8)^2 - 5
Step-by-step explanation:
subtracting from x inside of the square translates the function to the right and adding to x inside of the square translates it to the left.
(x-8)^2 - 1 translates the function 8 units to the right
subtracting from the constant translates the function down and adding translates it up.
x^2 - 5 translates the function 4 units down
Therefore, (x-8)^2 - 5 translates the function 8 units to the right and 4 units down

"select all the numbers that are solutions to the equation x^3=27"
The x = ∛27 and x = 3 are solution to the equation x³=27 option (B) and option (C) are correct.
What is a cube root?It is defined as the sum of two or more numbers. The original number is obtained by multiplying the cube root of a number three times; for example, the cube root of x is z.
We have equation:
x³ = 27
Taking cube root both side
∛x³ = ∛27
x = ∛27
x = 3
Thus, the x = ∛27 and x = 3 are solution to the equation x³=27 option (B) and option (C) are correct.
