Step-by-step explanation:
A team of biologists tagged 48 seals off the coast of an island.
later they captured a sample of seals from the same area and 15% of them had tags.
Estimate the total number of seals.
15 : 100 : : 48 : x
x
=4,800/15
=320
The total number of seals is about 320.

Michelle wants to make a long-term investment. She wants to triple an initial investment of
$2,000. If she invests at a simple interest rate of 12% per year, approximately how long will it
take her principal to triple?
Answer:
It will take approximately 17 years
Step-by-step explanation:
Let the initial investment be x
The investment plus the principal yields 3x
The interest is thus 3x-x = 2x
Formula for simple interest is;
I = PRT/100
R is rate = 12%
T is time = ?
x =$2,000 which is the principal
2x = x * 12 * T/100
2 = 12t/100
12t = 200
t = 200/12
t = 16.67 which is approximately 17 years

The line CD passes through the points C (2.-1) and D (1, 1). Which of the
following represents the equation of the line in Point-Slope Form?*
Answer:
The equation of the line in Point-Slope Form will be:
[tex]y + 1 = -2(x - 2)[/tex]
Also, check the attached graph below.
Step-by-step explanation:
Given the points
C(2, -1)D(1, 1)Determining the slope between the points C (2.-1) and D (1, 1).
(x₁, y₁) = (2, -1) (x₂, y₂) = (1, 1)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [1 - (-1)] / [1 - 2]
= [1+1] / [-1]
= [2] / [-1]
= -2
Thus, the slope of the line = m = -2
The point-slope form of the line equation is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
(x₁, y₁) = (2, -1)m = -2substituting the values m = -2 and the point (x₁, y₁) = (2, -1) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-1) = -2 (x - 2)[/tex]
[tex]y + 1 = -2(x - 2)[/tex]
Therefore, the equation of the line in Point-Slope Form will be:
[tex]y + 1 = -2(x - 2)[/tex]
Also, check the attached graph below.

India has a population density of 840 people per sq. mile. If we estimate the population of the US to be 300,000,000 and the total land area to be 3,500,000 sq miles, what is our population density?
85.7 people/ sq mi
8 people/ sq mi
840 people/sq mi
300,000,000 people/ sq mi
Answer:
A. 85.7 people/ sq miStep-by-step explanation:
Population density is:
Pd = population / areaPd = 300000000 people / 3500000 sq mi = 85.7 people/ sq miCorrect option is A

A website averages 800 visitors per day.Based on that rate,what percent of a weeks visitor come to the website on an average day?Round your answer to the nearest tenth.
Answer:
[tex]14.2857[/tex] % of a weeks visitor come to the website on an average day
Step-by-step explanation:
Visitors on the website per day [tex]= 800[/tex]
Visitor on the website in seven day [tex]= 800*7[/tex]
Percent of visitor on any average to the total visitors in a week
[tex]= \frac{800}{800*7} *100\\= \frac{100}{7}\\= 14.2857[/tex]

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Hudson sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
224 visitors purchased no costume.
103 visitors purchased exactly one costume.
32 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.
Answer:
62%
Step-by-step explanation:
Given the information :
224 visitors purchased no costume.
103 visitors purchased exactly one costume.
32 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.
Probability that next person will purchase no custome:
Probability = no of successes / total number of trials
Total number of trials :
(purchase no custome + purchase exactly one + purchase more than one)
= (224 + 103 + 32) = 359
Hence, Probability that next person will purchase no custome:
= 224 / 359
As a percentage :
(224 / 359) * 100%
= 0.6239554 * 100%
= 62.39 %
= 62% ( nearest whole percent)

HELP ASAP YALL- PLS
Answer: x = 4
Step-by-step explanation:
since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.
so, i redrew them next to each other, so i could compare them easily.
i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!
so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.
hope this helps! xoxo
