An irregular plane figure drawn on graph paper is framed 15 by 40 rectangle.To find its area,10,000 random points are generated,and 5,710 of them land inside the irregular region what is the area of the irregular region to the nearest integer
=========================================================
Explanation:
A = number of points that land inside the irregular figureB = number of randomly generated points totalIn this case,
A = 5,710B = 10,000Divide A/B to find the experimental probability of landing inside the figure
A/B = (5,710)/(10,000) = 0.571
There's about a 57.1% chance of landing inside the figure.
The entire region is 15 units by 40 units, giving an overall area of 15*40 = 600 square units.
Roughly 57.1% of this total area would be taken up by the irregular figure
57.1% of 600 = 0.571*600 = 342.6 which rounds to 343
The area of the irregular region is about 343 square units

Sal the sloth takes one hour to travel 7 1/2 feet. If he continues to travel at the same rate, how long will it take him to travel 30 feet?
Answer:
4 hours
Step-by-step explanation:
Since we know he travels at a rate of 1:7.5 all we have to do is divide 7.5 by 30. Do you use proportions? You can set this up as a proportion and the find answer easily.
1[tex]\frac{1}{7.5} =\frac{x}{30}[/tex]
Now we cross product.
7.5 multipled by x =7.5x
1x30=30
so now we have
7.5x=30
Now we have to divide 7.5 on both sides which gives us

Lillie has read 45 books and read 10 books every year. Dean has read 23 books and reads 12 books every year. How many years will Dean take to read as many books as Lillie?
Answer:
11 years
Step-by-step explanation:
x = years to equal
45 + 10x = 23 + 12x
22 = 2x
x = 11 years
It will take 11 years for Dean to read as many books as Lillie.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Number of books read by Lillie every year = 10 books
Total number of books already read = 45 books
The number of books, n, read by Lillie in t years,
n = 45 + 10t
Number of books read by Dean every year = 12 books
Total number of books already read = 23 books
The number of books, n, read by Lillie in t years,
n = 23 + 12t
Dean read as many books as Lillie, when,
23 + 12t = 45 + 10t
12t - 10t = 45 - 23
2t = 22
t = 11
Hence the number of books read by both will be same in 11 years.

In Exercise 3, one equation relating the times Eric spends running and walking to reach the goal of covering 1600 meters is 200x + 80y=1600. Suppose Eric runs and walks for a total of 12 minutes to reach his goal.
Answer + Step-by-step explanation:
let x be the time that Eric spends running
y be the time that Eric spends walking
a) the statement “Eric runs and walks for a total of 12 minutes to reach his goal” is equivalent to the equation: x + y = 12
b) the coordinates of the intersection point are (5.333... , 6.666...)
Interpretation:
the time that Eric spends running is 5.333... minutes
the time that Eric spends walking is 6.666... minutes
Answer:
Given equation:
[tex]200x+80y=1600[/tex]
where:
x = time Eric runs (in mins)y = time Eric walks (in mins)Part (a)If Eric runs and walks for a total of 12 minutes, then:
[tex]x+y=12[/tex]
Part (b)To graph:
Rewrite both equations to make y the subjectFind the x-interceptFind the y-interceptConnect the two points with a straight line[tex]200x+80y=1600 \implies y=20-\dfrac{5}{2}x[/tex]
[tex]\textsf{x-intercept}: \quad 20-\dfrac{5}{2}x=0 \implies x=8 \implies (8,0)[/tex]
[tex]\textsf{y-intercept}: \quad 20-\dfrac{5}{2}(0)=20 \implies (0,20)[/tex]
[tex]x+y=12 \implies y=12-x[/tex]
[tex]\textsf{x-intercept}: \quad 12-x=0 \implies x=12 \implies (12,0)[/tex]
[tex]\textsf{y-intercept}: \quad 12-0=12 \implies (0,12)[/tex]
Point of intersection (equate equations):
[tex]\begin{aligned}20-\dfrac{5}{2}x &=12-x\\20-12 &=\dfrac{5}{2}x-x\\8&=\dfrac{3}{2}x\\16 &=3x\\x &=\dfrac{16}{3}\end{aligned}[/tex]
[tex]y=12-\dfrac{16}{3}=\dfrac{20}{3}[/tex]
[tex]\implies \left(\dfrac{16}{3},\dfrac{20}{3}\right)[/tex]
The point of intersection tells us that Eric runs for 16/3 mins and walks for 20/3 minutes.

In a company, there are 28 total employees. All employees who have worked there for more
than five years receive a gift.
If eleven employees have received the gift, what is the probability that a randomly
selected employee has received the 5-year gift?
The probability that a randomly selected employee has received the 5-year gift is 39.29%
What is the probability?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that a randomly selected employee has received the 5-year gift = number of employees who have received the gift / total number of employees
11/28 x 100 = 39.29%

37. Watering a lawn requires 623 gallons of water for
every 1000 sq. ft. What is the rate of gallons per square
foot?
The rate of gallons per square foot is 0.624 gallons per square foot.
What is a rate?A rate demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B). This indicates that you're dividing information A by B.
In this scenario, watering a lawn requires 623 gallons of water for every 1000 sq. ft.
The rate of gallons per square foot will be:
= Number of gallons / Square foot
= 623 / 1000
= 0.623

what is 2.5 in a fraction?
Answer: 5/2
To convert 2.5 into a fraction, firstly we will write the number in x/y form, where x and y are positive integers. So, 2.5 can be written as 2.5/1. For the removal of the decimal, we multiply and divide by 10. And we get, 2.5/1 x 10/10 = 25/10 = 5/2.

Does the equation below represent a lunar relationship? Justify your response. 2x - 5y= -15
Answer:
Yes, the equation represents a linear relationship.
Step-by-step explanation:
If you graph it, it is a line.
Also, the exponent on the x and the y is exactly 1. There are no variables in the denominator, nor inside a radical. There are no squared, cubes or higher exponents. All these things will make an equation NOT linear.

Bernoulli trials are those trials that end up randomly either on success (with probability p) or on failures( with probability 1- p = q (say))

[tex]X \sim B(n,p)[/tex]
The probability that out of n trials, there'd be x successes is given by
