What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y=5/4x +1 and y=5/4x-7
4y= 5x+ 4 and 4y= 5x-7
Now, [tex]a_1[/tex]= 4, [tex]b_1[/tex]= 5, [tex]c_1[/tex]= 4
[tex]a_2[/tex]= 4, [tex]b_2[/tex]= 5, [tex]c_2[/tex]= -7

Required:
Calculate the 99% confidence interval for population mean μ. Find the closest answer
Answer: 60.93 < μ < 69.07
Step-by-step explanation: The true mean of a set of data is between an interval of values with a percentage of precision, e.g., a 99% confidence interval means we are 99% confident the true mean is between the lower and upper limits.
To find the interval, use
x±[tex]z\frac{s}{\sqrt{n}}[/tex]
z is z-score related to the % of confidence level
In this case, a 99% confidence interval is 2.576
x is sample mean
Calculating:
[tex]x=\frac{63+69+62+66}{4}[/tex]
x = 65
65±[tex]2.576\frac{3.16}{\sqrt{4}}[/tex]
65±4.07
Confidence Interval: 60.93 < μ < 69.07
Meaning that we are 99% sure the population means is between 60.93 and 69.07.

Based on experience, the probability that an incoming email is spam (an undesired message of solicitation) is 38%. If three emails are in my inbox, what is the probability that:A. All three messages are spam.B. At least one of the three messages are spam.C. None of the three messages are spam.
Answer:
0.0549
0.7617
0.2383
Step-by-step explanation:
Given that:
Probability that incoming email is spam ;
P(spam) = 0.38
If three emails are in my inbox, what is the probability that:
A. All three messages are spam.
P(1st message being spam) * p(second message being spam) * p(3rd message being spam)
= (0.38) * (0.38) * (0.38)
= 0.054872
= 0.0549
B. At least one of the three messages are spam.
1 - p(none of the 3 messages are spam)
P(none of the 3 messages are spam)
P(not spam) = 1 - p(spam) = 1 - 0.38 = 0.62
1 - [P(not spam) * p(not spam) * p(not spam)]
1 - (0.62 * 0.62 * 0.62)
= 1 - 0.238328
= 0.761672
= 0.7617
C. None of the three messages are spam.
P(not spam) = 1 - p(spam) = 1 - 0.38 = 0.62
P(not spam) * p(not spam) * p(not spam)
(0.62 * 0.62 * 0.62)
= 0.238328
= 0.2383

Which best describes how to solve the equation for x.
x/c = d
A. Multiply both sides by d.
B. Multiply both sides by c.
C. Divide both sides by d.
D. Divide both sides by c.
Answer:
B. multiply both sides by c.
Step-by-step explanation:
To solve the equation for x, you have to isolate the x variable on one side of the equation. To do this, do the opposite of any operation applied to x to remove other variables from the x's side of the equation:
x/c = d
multiply both sides of the equation by c to isolate x:
(x/c) * c = d * c
x = dc
Now x can be solved for.

Erin has quarters and nickels for a total of 16 coins. The value of his coins is $2.60. Let represent the number of quarters and y represent the number of nickels
Note: Consider we need to find each type of coins he has.
Given:
Erin has quarters and nickels for a total of 16 coins.
The value of his coins is $2.60.
To find:
The number of each type of coins.
Solution:
Let x represent the number of quarters and y represent the number of nickels.
According to the question,
Total coins : [tex]x+y=16[/tex] ...(i)
Total value : [tex]0.25x+0.05y=2.60[/tex] ...(ii)
Multiply equation (i) by 0.25 and subtract the result from (ii).
[tex]0.25x+0.05y-0.25(x+y)=2.60-0.25(16)[/tex]
[tex]0.25x+0.05y-0.25x-0.25y=2.60-4[/tex]
[tex]-0.20y=-1.40[/tex]
Divide both sides by -0.20.
[tex]y=7[/tex]
Put y=7 in (i).
[tex]x+7=16[/tex]
[tex]x=16-7[/tex]
[tex]x=9[/tex]
Therefore, the number of quarters is 9 and number of nickels is 7.

Fraction of Book Dillon Read on Monday and Tuesday= [tex]\frac{1}{5}+\frac{2}{5}[/tex]
[tex]=\frac{1+2}{5} \ (Taking \ LCM \ of \ 5 \ and \ 5 \ we \ get \ 5) \\=\frac{3}{5}[/tex]
So, Fraction of Book Dillon Read on Monday and Tuesday is [tex]\mathbf{\frac{3}{5} }[/tex]
The zoom feature on a camera lens allows you to dilate what appears on the display. When you change from 100% to 600%, the new image on your screen in an enlargement of the original image with a scale factor of 5. If the new image is 36 millimeters wide, what was the width of the original image?
A: 6 mm
B: 2mm
C: 12 mm
D:5 mm
Answer:6mm
Step-by-step explanation:
So we know that you started with 100% and ended with 600% to get from 100 to 600 you would need to multiply by 6
100 * 6 = 600
So you know that to get back to your original number you would need to divide by 6
If you are trying to figure out what the original width is you would divide your current number by 6 to get the original number
36 / 6 = 6

Rosa climbs a 16-meter tower to ride a straight water slide. After landing in the slash pool, she walks 9 meters back to the base of the tower. What is the length of the slide
Answer:
The length of slide is 18.36 meters
Step-by-step explanation:
The given scenario forms a right-angled triangle where
The height of tower id perpendicular, the distance between slash pool and base of tower is base and the length of slide will be hypotenuse.
Height of tower = h = 16 meters
Distance between slash pool and base of tower = b = 9 meters
Length of slide = s = ?
As it is a right angled triangle, we can use Pythagoras theorem to find the length of slide
Pythagoras theorem states that:
[tex](Hypotenuse)^2 = (Base)^2+(Perpendicular)^2\\s^2 = b^2+h^2\\s^2 = (9)^2+(16)^2\\s^2 = 81+256\\s^2 = 337\\s^2 = 18.36\ meters[/tex]
Hence,
The length of slide is 18.36 meters

A cheese can be classified as either raw-milk or pasteurized. 82% of cheeses are classified as pasteurized.
a. Two cheeses are chosen at random. What is the probability that both cheeses are pasteurized?
b. Four cheeses are chosen at random. What is the probability that all four cheeses are pasteurized?
c. What is the probability that at least one of four randomly selected cheeses is raw-milk? Would it be unusual that at least one of four randomly selected cheeses is raw-milk?
Answer:
Step-by-step explanation:
A cheese is said to be classified as either raw-milk or pasteurized.
Given that: 82% is pasteurized,
Then:
Supposed two cheeses are chosen at random;
P(both cheeses are pasteurized) = 0.82 × 0.82
= 0.6724
If four cheeses are chosen at random;
P(that all four cheeses are pasteurized) = 0.82 × 0.82 × 0.82 × 0.82
P(that all four cheeses are pasteurized) = 0.452
The required probability for at least one of the four randomly selected cheeses is raw milk is:
P(at least one of the randomly selected cheese is raw milk) = 1 - P(that all four cheeses are pasteurized)
P(at least one of the randomly selected cheese is raw milk) = 1 - 0.452
P(at least one of the randomly selected cheese is raw milk) = 0.548
However, since the probability that at least one of the randomly selected cheese is raw milk is greater than one; then we can conclude that;
It is not unusual that at least one of four randomly selected cheeses is raw-milk.

What is the Area of a Rectangle?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.
Area of a rectangle = length × width.
The amount of square feet of outdoor carpet needed
= area of the largest rectangle in the image - (area of medium rectangle + area of the smallest rectangle)
The amount of square feet of outdoor carpet needed
= 12 × 4 - (3 × 2 + 2 × 1)
= 48 - (6 + 2)
= 40 ft²
Thus, 40 ft² outdoor carpet needed.
