Answer:
option 2 : y-7 = 2(x-1)
Step-by-step explanation:
the fastest way is to simply put the x- and y-values of both points into the equations, and see, which one is true for both points.
the first option is only true for the second point
7-7 = 4(1-1)
0 = 4×0 = 0
but for the first point
3-7 = 4(-1 - 1)
-4 = 4×-2 = -8
-4 = -8 is false
the second option then is true for both points
7-7 = 2(1-1)
0 = 0
3-7 = 2(-1 - 1)
-4 = 2×-2 = -4

Companies, Inc. so you did some research and found out that companies belonging to this group has an average gain of
0.8
percent and standard deviation of
0.7
percent. Given that a positive percent (gain) means profit and a negative percent means a loss. If you choose
20
companies, what is the probability that the companies are gaining more than
1
percent?
Answer:
1.2803
Step-by-step explanation:
According to the Question,
Given That, You want to invest in companies belonging to Gispa Group of 1 Companies, Inc. so you did some research and found out that companies belonging to this group have an average gain of 0.8 percent and a standard deviation of 0.7 percent. And, a positive percent (gain) means profit and a negative percent means a loss. If you choose 20 companies.Therefore, We have Average Gain(ц) = 0.8%
Standard deviation(σ) = 0.7%
Number of Companies(n) = 20
So, the probability that the companies are gaining more than 1 percent is[tex]X_{i}[/tex] = (σ² × n) / ц ⇒ (0.7²×20) / (0.8*10) = 1.2803

Answer:
[tex]x=65[/tex]
Step-by-step explanation:
Area of a triangle is always 180 degrees...
In this triangle we have two values given, lets make an equation & solve it:
[tex]x+68+47=180[/tex]
[tex]x+115=180[/tex]
[tex]x=180-115[/tex]
[tex]x=65[/tex]
To check if you have the right answer, add all the angles to get 180:
[tex]68+47+65=180[/tex]
Therefore, x = 65

What is the slope of this equation? Y=1/3x+4
Answer:
slope = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x + 4 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]

The area of a flower garden is 60m2. One third of it was used for growing roses and the remaining area was divided into two equal parts. Find the area of each remaining part?
Given:
The area of a flower garden is 60 m².
One third of it was used for growing roses and the remaining area was divided into two equal parts.
To find:
The area of each remaining part.
Solution:
It is given that the area of a flower garden is 60 m² and one third of it was used for growing roses. So, the remaining part is:
[tex]\text{Remaining}=60-\dfrac{1}{3}\times 60[/tex]
[tex]\text{Remaining}=60-20[/tex]
[tex]\text{Remaining}=40[/tex]
The remaining area was divided into two equal parts. So, the area of each remaining part is:
[tex]\text{Area of each remaining part}=\dfrac{40}{2}[/tex]
[tex]\text{Area of each remaining part}=20[/tex]
Therefore, the area of each remaining part is 20 m².
the sum of three numbers is 62 the second number is equal to the first number diminished by for the third number is four times the first
Answer:
11, 7, 44
Step-by-step explanation:
a+b+c = 62
a-4 = b
c = 4×a
I think you meant "diminished by four", right ?
=>
a + a-4 + 4×a = 62
6×a - 4 = 62
6×a = 66
a = 11
=>
b = 11 - 4 = 7
c = 4×11 = 44

FAST PLEASE HELP MEEE: At a certain high school, 35 students play only stringed instruments, 10 students play only brass instruments, and 5 students play both. There are also 5 students who play neither stringed nor brass instruments. what is the probability that a randomly selected student plays either a string or brass instrument?
P(AUB)={?}
Answer:
10/11
Step-by-step explanation:
35 stringed , 5 string and brass, 10 brass, 5 play neither string nor brass
P (A or B ) = students that play string or brass / total number of students = 35+5+10/ 35+5+10+5 = 50/55 = 10/11

Joseph has 22 gallons of fertilizer. He uses 7 quarts to fertilize his plants.
How many quarts of fertilizer are left?
The solution is:
48.6 quart of fertilizer is the total fertilizer will Alan need for his two fields.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
The directions say to use 4/5 of a quart of fertilizer for each acre of land.
Alan has two fields,
Field 1
22 1/2 acre of land
1 acre of land = 4/5 quart
22 1/2 acre of land = x
Cross Multiply
x = 22 1/2 × 4/5
x = 45/2 × 4/5
x = 18 quart of fertilizer
Field 2
38 1/4 acres of land
1 acre of land = 4/5 quart
38 1/4 acre of land = x
Cross Multiply
x = 38 1/4 × 4/5
x = 153/4 × 4/5
x = 30.6 quart of fertilizer
The total fertilizer that Alan will need for his two fields is calculated as:
18 quart of fertilizer + 30.6 quart of fertilizer
= 48.6 quart of fertilizer
Hence, 48.6 quart of fertilizer is the total fertilizer will Alan need for his two fields.

Find the missing side length
Answer: Question 1: A. 48 would the answer
Answer: Question 2: C. 48 would be the answer
Hope this help...
Have a great day.
Answer:
C ) 48
Step-by-step explanation:
To begin, you have to figure out which angles correspond on the two triangles.
So here are the angles that correspond:
U = N
T = M
S = L
So, ST would be similar to LM so 32 and 8 will be similar.
And UT will be similar to NM so the missing length and 12 are similar.
To begin, find out the scale factor by dividing 32 by 8 to get 4.
Then, multiply 12 by 4 to get 48 for the missing length.
Transform the equation to isolate x: ax = bx + 1. How is the value of x related to the difference of a and b?
How can Victoria justify Step 3 of her work?
Answer:
ans: x= 1/(a-b)
Step-by-step explanation:
given equation is
ax = bx + 1
to isolate x , take bx to left side
or,
subtract bx on both sides , I.e
ax - bx = 1
x( a- b) = 1
x = 1/(a- b)
Fast Rental Services and Red Rent Services provide rental cars. Fast Rental Services charges a flat fee of $4.50, plus $0.75 for every mile traveled. On the other hand, Red Rent Services charges a flat fee of $7.50, plus $0.65 for every mile traveled. Which equation could be used to find the distance, d, when the cost of renting the cars from both the companies are the same?
Answer:
4.50+.75d=7.50+.65d
Step-by-step explanation:
Y=4.50+.75d equation 1
y=7.50+.65d equation 2
4.50+.75d=7.50+.65d sub value of y in equation 2 into equation 1
.10d=3.00 simplify equation
d=30
check answer by subbing 30 for d into each equation.
y=4.50+.75(30)
y=4.50+22.50
y=27
y=7.50+.65(30)
y=7.50+19.50
y=27
both equations equal so 30 is the correct distance for when Fast Rental equals Red Rent

What is the solution to the linear equation? 2/5 + p = 4/5 + 3/5p
Answer:
p=1
Step-by-step explanation:
2/5 + p = 4/5 + 3/5p
Multiply each side by 5 to clear the fractions
5(2/5 + p) = 5(4/5 + 3/5p)
2 +5p = 4 + 3p
Subtract 3p from each side
2+5p-3p = 4+3p-3p
2+2p = 4
Subtract 2 from each side
2+2p -2 = 4-2
2p =2
Divide by 2
2p/2 = 2/2
p=1

What is area of rectangle ?"Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides."
Given,
A gallon of paints covers 300 square feet.
Area of the first two walls is [tex]2*25*12[/tex] = 600 square feet
Area of the second two walls is [tex]2*20*12[/tex] = 480 square feet
Total area of the room is = 480+600 = 1080 square feet
The paint required for 1 feet is = 1/300
So, the paint required for 1080 feet is = 1080/300 =3.6
Hence, the paint required to cover the entire room is = 3.6 gallon
