What is an equation of the line that passes through the points (4, -2) and (8, 3)?
Answers
First, find the slope of the two points.
y2-y1/x2-x1
3+2/8-4
slope=5/3
Then use the point slope formula to create an equation
y-y1=m(x-x1)
y-3=5/3(x-8)
y-3=5/3x-40/3
y= 5/3x - 31/3
The equation of the line that passes through the points (4, -2) and (8, 3) is
y = (5/4)x - 7.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Points:
(4, -2) and (8, 3)
The equation of a line is y = mx + c.
m = (3 + 2)/(8 - 4)
m = 5/4
Now,
(4, -2) = (x, y)
-2 = 5/4 x 4 + c
-2 = 5 + c
c = -2 - 5
c = -7
Thus,
The equation of a line is y = (5/4)x - 7.

how to expand and simplify?
\(2( \sqrt{15} - 3 \sqrt{5})^{2} \)
Answers
By the distributive property,
2 (√15 - 3√5)² = 2 (√15 - 3√5) (√15 - 3√5)
… = 2 ((√15)² + 2 (√15) (-3√5) + (-3√5)²)
In other words, we use the identity
(a + b)² = a² + 2ab + b²
with a = √15 and b = -3√5.
Then
2 (√15 - 3√5)² = 2 (15 - 6√(15•5) + 9•5)
… = 2 (15 - 6√(3•5²) + 9•5)
… = 2 (15 - 30√3 + 45)

an envelope contains eight bills: 2 ones, 2 fives, 2 tens, and 2 twenties. two bills are drawn at random without replacement. what is the probability that their sum is $20 or more?
Answers
The probability that their sum is $20 or more is 1/2 that is calculated by using given information.
Probability is surely how in all likelihood some thing is to happen. Whenever we are uncertain approximately the final results of an event, we are able to communicate approximately the chances of positive outcomes—how in all likelihood they are. The evaluation of occasions ruled with the aid of using possibility is known as statistics.
The probability of choosing bills out of 8.
\(\text{{8}} \times{2}=\dfrac{8\times7}{2\times1}\\\\=28 \text{ ways}\)
Thus, there are total 28 ways to choose 2 bills out of 8. There are 12 ways to choose a twenty and some other non-twenty bill. There is 1 way to choose both twenties, and also 1 way to choose both tens.
Adding these up, we find that there are a total of 14 ways to attain a sum of 20 or greater. The probability can be shown as follows:
\(\text { Probability} =\dfrac{14}{28}\\\\= 1/2\)

Mean absolute percentage error is used in situations where you need to compare forecasting methods for different time periods.
The most used metric for gauging forecast accuracy is mean absolute percent error. It belongs to the category of scale-independent percentage errors, which may be used to compare series on various scales.
MAPE = mean (| eᵢ |/yᵢ )*100
where eᵢ is the error term and yᵢ is the actual data at the time i.
The drawback of MAPE is that it loses definition if the actual figure for any observation in the data has a value of 0.

a rectangle has perimeter 52 km, and its area is 165 sq-km. find the dimensions of this rectangle. (for purposes of this problem only, the width is shorter than the length.)
Answers
The dimensions of the rectangle: length = 15 km and width = 11 km
Let l be the length of rectangle and w be the width of the rectangle.
A rectangle has perimeter 52 km
Using the formula of the perimeter of rectangle we get an equation,
2(l + w) = 52 ............(1)
And its area is 165 sq-km.
Using the formula of the area of rectangle we get an equation,
l * w = 165 ............(2)
From equation (1),
l = 26 - w
Subatitute above value of l in equation (2),
(26 - w) * w = 165
26w - w² = 165
w² - 26w + 165 = 0
(w - 15)(w - 11) = 0
w = 15 or w = 11
For w = 15,
l = 26 - 15
l = 11
For w = 11,
l = 26 - 11
l = 15
But as we know, the length of rectangle is always greater than the width,
l = 15 and w = 11 is true .
Therefore, the length of rectangle = 15 km and width of rectangle = 11 km

carl throws a single die twice in a row. for the first throw, carl rolled a 2; for the second throw he rolled a 4. what is the probability of rolling a 2 and then a 4? answer choices are in the form of a percentage, rounded to the nearest whole number.
Answers
To the nearest whole number, the probability of rolling a 2 and a 4 is 2.8%.
A 2 rolling up on the first throw has a 1/6 chance of happening. Given that a 2 was rolled on the first throw, the likelihood of rolling a 4 on the second throw is equally 1/6. We will have to multiply the probabilities to get the probability of both the events happening,
= (1/6)x(1/6)
= 1/36.
We get 2.8% after converting to a percentage and rounding to the next full amount. So, the chance of rolling a 2 and then a 4 is found to be 2.8% chance.

a triangular fence is being built to surround a garden. if two of the side lengths must be 4 feet and 12 feet, which inequality could be solved to determine the minimum length of the third side?
Answers
The minimum length of the third side must be greater than 16 feet.
The minimum length of the third side can be determined using the Triangle inequality theorem. This theorem states that the sum of any two sides of a triangle must be greater than the length of the third side. The Triangle Inequality Theorem can be expressed by the following inequality: a + b > c, where a, b, and c are the lengths of the three sides of the triangle. In this case, we have two sides of 4 feet and 12 feet, so the inequality can be written as 4 + 12 > c, which simplifies to 16 > c. Solving for c yields c > 16, which means that the minimum length of the third side must be greater than 16 feet.

A grocer has two kinds of tea: one selling for 80 cents a pound and the other selling for 60 cents a pound. How many pounds of each kind must be used to make 50 pounds worth 74 cents a pound?
Answers
Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
Answer:
35 pounds of tea for 80 cents.
15 pounds of tea for 60 cents.
Step-by-step explanation:
x · 80 + y · 60 = 50 · 74
x + y = 50 · (- 60)
80x + 60y= 50 · 74
- 60x - 60y = -50 · 60
20x = 50 · (74-60) = 50 · 14
x = 50 · 14/20
35 pounds of tea for 80 cents.
y = 50 - 35 =
15 pounds of tea for 60 cents.
