A) The probability distribution below is for the number of radios sold at Kisumu City Sound Store in a week. Radios(X) 0 1 2 3 4 5 P(X=x) 0.03 0.20 0.50 0.20 0.05 0.02 Determine: i. The expected weekly radio sales (3 Marks)
Answer:
2.1
Step-by-step explanation:
Given :
Radios(X):_0 ___ 1 ___2 ___ 3 ___4 ___5
P(X=x) : 0.03 0.20 0.50 0.20 0.05 0.02
The expected weekly radio sales :
Σ(X) * p(x) : (0*0.03) + (1*0.20) + (2*0.50) + (3*0.20) + (4*0.05) + (5* 0.02) = 2.1
Hence, expected weekly radio sale = 2.1
of the 80 students who signed up for after school clubs , 16 students signed up for the art club and the the other one signed up for different clubs find the ratio of the number of students who signed up for art club and student who sighned up for other clubs express your answer in simplest form
Answer:
Ratio of student who signed up for art club:
1/5
Ratio who signed other club:
4/5
Step-by-step explanation:
First find out ratio who signed up for art club
you have 16 out of 80
find the common factor: 16
16/16 = 1
80/16 = 5
so 1/5
other clubs is the rest so 5/5 - 1/5 = 4/5

what is the slope between (-12, 1), (4,1)?
Answer:
[tex]m=0[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Point (-12, 1)
Point (4, 1)
Step 2: Find slope m
Substitute [Slope Formula]: [tex]m=\frac{1-1}{4+12}[/tex]Subtract/Add: [tex]m=\frac{0}{16}[/tex]Divide: [tex]m=0[/tex]Answer:
zero; it is a horizontal line
Step-by-step explanation:
equation of slope: [tex]\frac{y1-y2}{x1-x2}[/tex] (-12, 1) (4, 1)
[tex]\frac{1-1}{-12-4}[/tex] = [tex]\frac{0}{-16}[/tex]
Because the numerator is zero, the slope of the line is zero. It is a horizontal line.
The equation of the line that contains diagonal HM is y = 2/3 x + 7.
What is the slope of the line that contains diagonal OE?
Answer:
The slope of the line that contains diagonal OE will be = -3/2
Step-by-step explanation:
We know the slope-intercept form of the line equation
y = mx+b
Where m is the slope and b is the y-intercept
Given the equation of the line that contains diagonal HM is y = 2/3 x + 7
y = 2/3 x + 7
comparing the equation with the slope-intercept form of the line equation
y = mx+b
Thus, slope = m = 2/3
We know that the diagonals are perpendicular bisectors of each other.As we have to determine the slope of the line that contains diagonal OE.
As the slope of the line that contains diagonal HM = 2/3
We also know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.
Therefore, the slope of the line that contains diagonal
OE will be = -1/m = -1/(2/3) = -3/2
Hence, the slope of the line that contains diagonal OE will be = -3/2
The winning time for the men's 400-meter race in each of the Olympic Games from 1976 to 1996 can be modeled by the equation y = −0.054x + 44.54 , where x is the number of years after 1976 and y is the winning time in seconds. If the relationship continues, which equation could be used to predict the winning time in the year 2020?
Answer:
D. y = −0.054(44) 44.54
Step-by-step explanation:
The difference in years from 1976 to 1996 is 20 years
But from 1976 to 2020 the years would be 44
So here put the value of x as 44
Therefore the equation that could be used for predict the winning time for the year 2020 is y = −0.054(44) 44.54
Hence, the correct option is d.
ANd the rest of the options are incorrect

find 3 consecutive numbers such that twice the greatest added to three times the least amount of 34.
Answer:
6
Step-by-step explanation:
2(x+2) + 3x
2x + 4 + 3x = 34
5x + 4 = 34
5x = 34–4
5x = 30
x = 30/5
x = 6

It usually takes Claude 40 minutes driving at 48 miles per hour to go from home to work. But due to road maintenance today, Claude has to take a detour, which makes the trip 8 miles longer than usual. What is the minimum speed Claude should travel so that he can reach the destination in less than 48 minutes?(1 point)
Answer: 50 miles per hour
Step-by-step explanation:
Find out the length of the normal route.
Distance = Speed * time
= 48 * 40/60
= 32 miles
The detour is 8 miles longer so the length is;
= 32 + 8
= 40 miles
What speed should he travel at to make it in 48 minutes. Remember speed is in miles per hours.
Speed = Distance/ time
= 40 / (48/60)
= 50 miles per hour
Answer:
50 miles per hour :)
Step-by-step explanation:
Distance = Speed * time = 48 * 40/60 = 32 miles
Detour is 8 miles longer so = 32 + 8 = 40 miles
In 48 minutes. Remember speed is in miles per hours.
Speed = Distance/ time
50MPH= 50 miles per hour

Your Explanation:
Answer:
No because if you set them equivelent to each other you get 12=0
Step-by-step explanation:
1/4(12x + 24) - 9x = -6(x + 1)
3x + 6 - 9x = -6x - 6
-6x + 6 = -6x - 6
12 = 0x

The difference between two num-
bers is 24. What are the numbers
if their sum is 78?
(Please help me!)
Answer:
51 and -27
Step-by-step explanation:
The sum of two numbers is 24 and their difference is 78. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 24. In other words, x plus y equals 24 and can be written as equation A:
x + y = 24
The difference between x and y is 78. In other words, x minus y equals 78 and can be written as equation B:
x - y = 78
Now solve equation B for x to get the revised equation B:
x - y = 78
x = 78 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 24
78 + y + y = 24
78 + 2y = 24
2y = -54
y = -27
Now we know y is -27. Which means that we can substitute y for -27 in equation A and solve for x:
x + y = 24
x + -27 = 24
X = 51
Summary: The sum of two numbers is 24 and their difference is 78. What are the two numbers? Answer: 51 and -27 as proven here:
Sum: 51 + -27 = 24
Difference: 51 - -27 = 78
Answer:
The numbers are 27 and 51
Explanation
x - y = 24
x + y = 78
Add together the equations
2x = 102
x = 51
Put into equation
51 - y = 24
27 = y
Which is greater 0.37 or 41%
Answer:
41% because if you put both of those numbers a decimal like this 0.37 and 0.41
It's greater
Step-by-step explanation:
Answer:
41%
Step-by-step explanation:
percentages are out of 100.
41% is equal to 0.41
and 0.41 is greater than 0.37

The radius of a circle is 6 yards. What is the circle's area?
Use 3.14 for PI
Answer:
113.04
Step-by-step explanation:
To calculate a circle's area, the formula is Pi R Squared. R is radius. Radius squared would be 36. (6*6) Now, multiplied by Pi, the area would be: 113.04. (36*3.14)
Answer:
113.04
Step-by-step explanation:
The radius of a circle is 6 yards. What is the circle's area?
r=6 yd
Use 3.14 for .
square yards
You answered:
113.1
square yards
remember
Use this formula to find the area from the radius.
A=r2
Use 3.14 as an approximation for .
≈3.14
solve
The radius is 6 yards. Replace r by 6 in the formula.
A
= r2
≈ 3.1462
≈ 3.1466
≈ 113.04
The area is about 113.04 square yards.

Answer:
The answer is
[tex] \sqrt{65} [/tex]
Step-by-step explanation:
We need to find the distance as instructed.
Its formula is:
[tex]d = \sqrt{(x_2 - x_1) ^{2} + (y_2 - y_1)^{2} } [/tex]
Let's plug in according to the formula and solve.
[tex]d = \sqrt{(x_2 - x_1) ^{2} + (y_2 - y_1)^{2} } \\ d = \sqrt{( - 7 - 1) ^{2} + (2 - 3)^{2} } \\ d = \sqrt{64 + 1} \\ d = \sqrt{65} [/tex]

Marcello is an artist who makes oil paintings and charcoal sketches. He sells each oil painting for $500 and each charcoal sketch for $300. Marcello wants to create 56 works total. Write and solve a system of equations to determine how many pieces of artwork he must sell in order to make exactly $20,000
Answer:
He needs to sell 25 pieces of artwork.
Step-by-step explanation:
$500 for an oil painting.
$300 for a charcoal sketch.
56 pieces of artwork total.
$20,000 goal.
500 + 300
= 800
$800 for 1 oil painting and 1 charcoal sketch.
20,000 ÷ 800
= 25
He needs to sell 25 pieces of artwork to make $20,000.

Find a formula for the transformation of reflection across the line l with equation y = -x.
Answer:
The rule or formula for the transformation of reflection across the line l with equation y = -x will be:
P(x, y) ⇒ P'(-y, -x)
Step-by-step explanation:
Considering the point
[tex]P(x, y)[/tex]
If we reflect a point [tex]P(x, y)[/tex] across the line [tex]l[/tex] with equation [tex]y = -x[/tex], the coordinates of the point P flips their places and the sign of the coordinates reverses.
Thus, the rule or formula for the transformation of reflection across the line l with equation y = -x will be:
P(x, y) ⇒ P'(-y, -x)
For example, if we reflect a point, let suppose A(1, 3), across the line [tex]l[/tex] with equation [tex]y = -x[/tex], the coordinates of point A flips their places and the sign of the coordinates reverses.
Hence,
A(1, 3) ⇒ A'(-3, -1)
