I've drawn a venn diagram to explain the distribution in this question and attached it.
From the venn diagram, we can see that;
(M) = 60
(S) = 50
(M ∩ S) = 20
Now, to find how many of them failed both subjects, we will use the formula;
100 = (M' ∩ S') + (M) + (S) - (M ∩ S)
Where (M' ∩ S') is number of people that failed both subjects
Plugging in the relevant values we have;
100 = (M' ∩ S') + 60 + 50 - 20
100 = (M' ∩ S') + 90
(M' ∩ S') = 100 - 90
(M' ∩ S') = 10
Yuri is 5 miles from home he walks home at a speed of 1.5 miles per hour. The variable x represents time in hours and y represents yuri's distance from home in miles. Which equation models this solution
Answer:
1.5x= y
Step-by-step explanation:
Speed = distance / time
The variable x represents time in hours and y represents yuri's distance from home in miles.
Therefore
Speed = y/ x
But distance = 5 miles and speed= 1.5 miles
1.5 = y/x
or
1.5x= y
For the corporate headquarters, an executive wants to place a company logo that is six feet in diameter with the sides of the H five feet tall on the front wall. What is the width x of the crossbar for the H?
Round to the nearest hundredth
The requried width of the crossbar for the H is 3.96 ft.
What are Pythagorean triplets?In a right-angled triangle, its sides, such as hypotenuse, perpendicular and base is Pythagorean triplets.
Here,
Let, from the figure,
b = 5
c = 1/2*6= 3
e = 1/2*b = 1/2*5 = 2.5
a = √[c²-e²]
a = √[3²-2.25²]
a = √9-5.0625
a = 1.98
x = 2a = 2*1.98=3.96
Thus, the requried width of the crossbar for the H is 3.96 ft.

2.0 x 10^5
Answer:
2^6 x 10^5
Step-by-step explanation:
10^5
= ( 2 x 5 )^5
= 2^5 x 5^5
2 x 10^5
= 2^1 x 2^5 x 10^5
= 2^( 1 + 5 ) x 10^5
= 2^6 x 10^5
Find the input (x) of the function y = 1/4x+ 12 if the output
(y) is 6
Answer:
x = -24
Step-by-step explanation:
y = 1/4x+12 (Substitute 6 for y)
6 = 1/4x+12 (Subtract 12 from both sides)
6-12= -6 so its now -6 = 1/4x and since its a fraction you want to multiply both sides by the reciprocal
4*-6 = 1/4x*4 (1/4*4=1 which is 1x or x)
-24 = x
Answer:
y=1/4x+12
6=1/4x+12
1/4x=6-12
1/4x=-6
0.25x=-6
x=-6÷0.25
x=-24

You pay $3 per square foot for carpeting. Which equation can be solved to find the
amount you will pay to cover a triangular section of the floor with a base of 2 yards and
a height of 5 yards?
Answer:
3 * (½*2*5) = x
Step-by-step explanation:
Cost of carpeting = $3 per square foot
We have a triangular section to cover having the following dimensions:
base = 2 yd
height = 5 yd
First, let's find the area of the section = area of triangle
Area of triangle = ½*base*height
Area of the triangular section of the floor = ½*2*5
If $3 will cover 1 ft², therefore,
x will cover ½*2*5
Thus:
3 * (½*2*5) = x
can you please help me find the area of the parallelogram!! can you show your work plz
Which are steps in the process of completing the square used to solve the equation 3 – 4x = 5x2 – 14x? Check all that apply.
3 = 5(x2 + 2x)
3 = 5x2 – 10x
4 = 5(x2 – 2x + 1)
8 = 5(x2 – 2x + 1)
3 = 5(x – 1)2
4 = 5(x – 1)2
StartFraction 8 Over 5 EndFraction = (x – 1)2
Answer:
1. 3 = 5x2 – 10x
2. 8 = 5(x2 – 2x + 1)
3. StartFraction 8 Over 5 EndFraction = (x – 1)2
Step-by-step explanation:
3-4x=5x^2-14x
3=5x^2-14x+4x
3=5x^2-10x
5x^2-10x-3=0
1. 3 = 5x2 – 10x
2. 8 = 5(x2 – 2x + 1)
8=5x^2-10x+5
8-5=5x^2-10x
3=5x^2-10x
3. StartFraction 8 Over 5 EndFraction = (x – 1)2
8/5=x^2-2x+1
Cross product
8=5(x^2-2x+1)
8=5x^2-10x+5
8-5=5x^2-10x
3=5x^2-10x
Answer:
3 - 4x = 5x2 - 14x
= 3 - 5x2 = - 14x + 4x
= 3 - 10 = 10x
= 7 = 10x
= x = 7/10
= x = 0.7

When a tree is planted, it is 6 feet tall. Each month, it grows by 2 feet. How tall will it get over time? How many feet will it be in 3 months?
After 3 months, the tree will reach a height of 12 feet.
Imagine you plant a tree that is initially 6 feet tall. Every month, it grows by 2 feet.
Let's denote the height of the tree at the start as H₀ = 6 feet. Since the tree grows 2 feet each month, we can express its growth rate as "2 feet per month." To calculate how tall it will be over time, we need to consider the number of months it has been growing.
After 1 month, the height of the tree will be:
H₁ = H₀ + (growth rate * number of months) = 6 + (2 * 1) = 8 feet.
After 2 months, the height of the tree will be:
H₂ = H₀ + (growth rate * number of months) = 6 + (2 * 2) = 10 feet.
After 3 months, the height of the tree will be:
H₃ = H₀ + (growth rate * number of months) = 6 + (2 * 3) = 12 feet.
So, after 3 months, the tree will be 12 feet tall.
We can also represent this growth pattern using a mathematical equation. Let "t" be the number of months the tree has been growing, and "Hₜ" be its height at time "t."
The equation for the height of the tree over time is given by:
Hₜ = H₀ + (growth rate * t).
Using this equation, you can plug in the value of "t" as 3 to find the height after 3 months:
H₃ = 6 + (2 * 3) = 12 feet.
In conclusion, the tree will keep growing 2 feet every month, and you can find its height at any given time using the formula Hₜ = H₀ + (growth rate * t). After 3 months, the tree will reach a height of 12 feet.

Building A is 490 feet tall and Building B is 754 feet tall. If the angle of depression from the top of Building B to the top of Building A is 46°, how far apart are the buildings?
Answer: [tex]254.94\ ft[/tex]
Step-by-step explanation:
Given
Building A is 490 feet tall and building B is 754 ft tall.
If the angle of depression from building B to the top of building A is [tex]46^{\circ}[/tex]
Difference in the height of the two buildings is [tex]754-490=264\ ft[/tex]
If the difference between them is [tex]x[/tex]
From the figure, we can write
[tex]\Rightarrow \tan 46^{\circ}=\dfrac{264}{x}\\\\\Rightarrow x=\dfrac{264}{\tan 46^{\circ}}\\\\\Rightarrow x=254.94\ ft[/tex]
Therefore, the two buildings are [tex]254.94\ ft[/tex] apart.

a shipement of 14 microwave ovens contains six defective units A vending company has ordered 4 of these units and selection will be random, what is the probability that all 4 units are good
Answer:
The probability that all 4 units are good is 10.66%.
Step-by-step explanation:
Given that a shipement of 14 microwave ovens contains six defective units, and a vending company has ordered 4 of these units and selection will be random, to determine what is the probability that all 4 units are good the following calculation must be performed:
14 - 6 = 8
8/14 x 8/14 x 8/14 x 8/14 = X
0.5714 x 0.5714 x 0.5714 x 0.5714 = X
0.1066 = X
0.1066 x 100 = 10.66
Therefore, the probability that all 4 units are good is 10.66%.

i want to fined out the digree of polynomial 5 x^4 + 3 x^2 + 1
Answer:
4
Step-by-step explanation:
The degree of a polynomial is the highest degree of a monomial contained within the polynomial. The degree of the monomial is the sum of the exponents on the variables. Example, the degree of -4x^6y is 6+1=7.
Example, the degree of 4x^8 is 8.
So the degree of 5x^4 is 4.
The degree of 3x^2 is 2.
The degree of 1 is 0 since there is no variable in this expression.
So the degree of 5 x^4 + 3 x^2 + 1 is 4.

Answer:
Function B > Function A > Function C
Step-by-step explanation:
For function A,
From the given table,
Two points are (3, 3) and (5, 7).
Rate of change of the function between these points = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{7-3}{5-3}[/tex]
= 2
For function B,
Rate of change = [tex]\frac{\triangle y}{\triangle x}[/tex]
Here, Δy = y-intercept = 3
And Δx = x-intercept = -5
Therefore, rate of change = [tex]\frac{3}{-5}[/tex]
= -0.6
For function C,
Equation of the line → y = 3x + 1
By comparing this equation with slope-intercept form of the equation,
y = mx + b
Slope of the line = m = 3
Rate of change = 3
Now we can write the rate of changes of each function from least to greatest.
-0.6 > 2 > 3
Function B > Function A > Function C
