Answer:
2.592 x 10^5
Step-by-step explanation:
1st step: Calculate for 1 day.
if 1 hour = 3.6 X 10³
24 hrs = (3.6 x 10³) X (2.4 x 10¹)
= 3.6 x 2.4 X 10⁴
= 8.64 x 10⁴
2nd Step: Calculate for 3 days;
if 1 day = 8.64 x 10⁴
3 days = (8.64 x 10⁴) X (0.3 x 10¹)
= 8.64 x 0.3 x 10^5
= 2.592 x 10^5

What is a number?A number is a mathematical object used to count, measure, and label. The original examples are natural number 1,2,3,4 and so forth.
Given number is 15.
A. natural numbers
The natural numbers are the set of all the whole numbers excluding zero. They are positive whole number.
Here, -15 is a negative number,
Hence, -15 is an not element of natural number.
B. real numbers
Real numbers are those numbers that has no imaginary part. It also include both rational and irrational number.
Since -15 has no imaginary part
Hence, -15 is an element of real number.
C. irrational numbers
An irrational number is real number that cannot be expressed as a ratio of two integers.
Here -15 can be expressed as ratio of two integers,
Hence,-15 is not an element of irrational number.
D. rational numbers
A rational number is real number that can be expressed as a ratio of two integers.
Here -15 can be expressed as ratio of two integers,
Hence, -15 is an element of rational number.
E. whole numbers
Whole numbers are positive numbers, including zero, without any decimal or fractional parts. Negative numbers are not considered "whole numbers."
Since,Negative numbers are not considered whole numbers
Hence, -15 is not an element of whole number.
F. integers
An integer is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043
Hence, -15 is an element of integers.
Hence, we conclude that,
-15 is an element of-
B. real numbers
D. rational numbers
F. integers

Answer:
If the hypotenuse of the 30 60 90 triangle is 7 sqrt 3, then the length of the longer side is equal to 7 x 3, or 21.
Now going to the 45 45 90 triangle, we can see that x is equal to 21[tex]\sqrt{2}[/tex]. This is because the hypotenuse of a 45 45 90 triangle is equal to the side length times sqrt 2.
So our answer is, 21[tex]\sqrt{2}[/tex].

Stella and Michael are helping their friend Austin move. Stella can move one box for every four boxes that Michael can move. If Stella moves ten boxes, how many boxes can Michael move?
Explanation:
Stella can move 1 box for every 4 boxes Michael moves.
She moves 10 boxes, so that must mean Michael moved 40 boxes (since 4*10 = 40).
Put another way, the ratio 1:4 bumps up to the equivalent form 10:40 after multiplying both parts by 10. The first value of each ratio is the amount of boxes Stella moves, and the second part is what Michael moves.
You could also solve it like this
1/4 = 10/x
1*x = 4*10
x = 40
In the second step, I used cross multiplication.

Find the probability that a randomly
selected point within the circle falls
in the white area.
r = 4 cm
2.5 cm
3 cm
3 cm
[?]%
Round to the nearest tenth of a percent.
Answer:
61.2%
Step-by-step explanation:
Area of the circle π(4²) = 50.265... cm²
Area of the triangle = ½(6)(6.5) = 19.5 cm²
probability of landing is white is
1 - (19.5 / 50.265) = 0.612059...
The probability that a randomly selected point within the circle falls in the white area is 61.22%.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
As we know the circle is a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
The total outcomes = The area of a circle
The area of the circle = πr²
The area of the circle = π(4)²
Because r = 4 cm
The area of the circle = 50.285 square cm
The area of the triangle = (1/2)(3+3)(4+2.5)
The area of the triangle = 19.5 square cm
The area of the white region = 50.285 - 19.5 = 30.785 square cm
Probability = 30.785/50.285
Probability = 0.6122 or
Probability = 61.22%
Thus, the probability that a randomly selected point within the circle falls in the white area is 61.22%.

The mayor of a large U.S. city is interested in addressing complaints from many property owners regarding recent property assessments. Many people feel that they are being overtaxed and that their assessments are too high. To study this issue, the mayor plans to hire consultants to randomly select homes in the city and have these homes independently assessed for value. However, she is concerned that the cost of sampling will be very high since the city is spread out over a wide geographical area. To potentially reduce the cost of sampling, which of the following statistical sampling techniques should be applied?
In order to reduce the cost of sampling, the cluster sampling should be applied.
Cluster sampling is a form of sampling techniques whereby the population that the researcher wants to study are divided into smaller groups which are called clusters.
Based on the question asked, since the the cost of sampling will be high for the entire population, the population can be divided into clusters after which the required people will be selected. This will help in reducing the cost.
In conclusion, the statistical sampling techniques that should be applied is the cluster sampling.

How to Determine the Domain and Range of a Function?A function is a relation that consists of a domain (a set of x-values) and a corresponding range (set of y-values).
Thus, each ordered pair in a function is expressed (x, y), where all values of x make up the domain, while tehri corresponding y-values make up the range of the function.
Thus, for a function given as, {(2,0), ( – 5, 1), (7,8), (6,0), ( – 7, 1)}:
The set of x-values is, -7, -5, 2, 6, and 7. Therefore, the domain is: { – 7, - 5, 2, 6, 7}.
The set of y-values is: 0, 1, and 8. Therefore, the range is: {0, 1, 8).

The perimeter of a triangle is 93 centimeters. If two sides are equally long and the third side is 9 centimeters longer than the others, find the lengths of the three sides.The length of each of the two equally long sides is ____ ▼ square centimeters centimeters and the length of the longer side is ____ ▼ square centimeters. centimeters.
Answer:
28 & 37 cm
Step-by-step explanation:
Perimeter(P)=9 cm
Let the equal sides(a) be x cm, then third side(b)=(x+9)cm
We have,
P=Sum of all sides
93=a+a+b
or,93=2a+(x+9)
or,93=2x+x+9
or,93-9=3x
or,84/3=x
therefore, x=28
Now,
Length of equal sides=x=28cm
Therefore, The length of each of the two equally long sides is 28 cm
The length of the longer side=(x+9)=28+9=37cm
