Bondu and Ansah fomed a company and agreed that their annual profit will be
shared in the ratio 4 : 5 respectively. Ir at the end of the year, Ansah received
GHE 5,000.00 more than Boadu, how much was Boadu's share?
Answer:
1. 68% owned a TV
2. 20,000.00
Step-by-step explanation:
1. answer is in the question
2. if Ansah got 5,000.00 more that Bondu that means Ansah is 5, if Ansah is 5 and gets 5,000.00 more that means the difference of 1 is 5,000.00 or 1= 5,000.00
4*5,000.00 = 20,000.00
Lets say you have a bunch of pennies that you are dividing into different groups. How many pennies could you have when you break the pennies into groups of 2 , you have 1 penny left over
Answer: We have an odd number of pennies.
Step-by-step explanation:
So we have N pennies.
When we wan to divide the N pennies into groups of 2, we have a penny left over.
This means that N is not divisible by 2.
The problem is that there are infinite natural numbers that are not divisible by two, this is the set of odd numbers.
And remember that an odd number can be written as:
N = 2*k + 1.
where k is an integer.
Then we want to divide this by 2 (divide N into groups of 2)
we have:
N/2 = (2*k + 1)/2 = 2*k/2 + 1/2 = k + 1/2.
So we have k groups of 2 pennies, and a penny leftover that we can not divide into two.

The linear function f is defined by f(x)= cx + d, where c and d are constants. If f(50) = 27,000 and f(100)= 38,000, what is the value of c?
Answer:
c = 220Step-by-step explanation:
f(x) = cx + d
For the first equation
f(50) = 27,000
Substitute the value of x that's 50 into the expression
That's
50c + d = 27,000
For the second equation
f(100) = 38,000
Substitute the value of x that's 100 into the expression
We have
100c + d = 38,000
Subtract the first equation from the second one to eliminate d
That's
100c - 50c + d - d = 38,000 - 27,000
50c = 11,000
Divide both sides by 50
We have the final answer as
c = 220Hope this helps you

A 1,000 ohm resistor has a tolerance of 20%. This means that the resistor actual value can be +-20%. What's the acceptable range of values for this resistor
Answer:
[800, 1200]
Step-by-step explanation:
We need to calculate the acceptable range of values for this resistor. The center point would be the nominal resistance: 1000 ohms.
20% above that would be 1.20(1000 ohms) = 1200 ohms, and 20% below would be (0.80)(1000 ohms) = 800 ohms.
Thus, the acceptable resistance range in ohms is [800, 1200]
In which of these situations would it be more appropriate to use a probability model rather than a regression/data-mining approach?
a. Predicting when the customer will make her next purchase.
b. Predicting which customer is most likely to churn in the next year.
c. Predicting the brand that the customer will buy during her next category purchase.
d. Predicting whether the customer will buy the brand at least once in the next year.
e. Predicting whether the customer will churn in the next year
Answer:
The correct options are b, c and d.
Step-by-step explanation:
The regression or data mining approach is used to predict the future value of the variable under study.
Whereas the probability model is used to predict the chances or likelihood of an event taking place.
Predicting which customer is most likely to churn in the next year.To predict which customer is most likely to churn in the next year, we need to compute the probability for customers who are likely to churn in the next year.
Thus, a probability model would be used.
Predicting the brand that the customer will buy during her next category purchase.Each brand has a specific probability of being purchased by a customer.
Thus, a probability model would be used.
Predicting whether the customer will buy the brand at least once in the next year.In this case also we need to compute the probability of a customer buying the brand at least once in the next year.
The correct options are b, c and d.
6/x = 2x+4/5
Multiply each side by the common denominator to find the
quadratic equation equivalent to this equation.
Answer:
5x² + 2x - 15 = 0
Step-by-step explanation:
Given
[tex]\frac{6}{x}[/tex] = 2x + [tex]\frac{4}{5}[/tex]
Multiply through by 5x ( common denominator )
30 = 10x² + 4x ( subtract 30 from both sides )
0 = 10x² + 4x - 30 ( divide through by 2 )
0 = 5x² + 2x - 15 , that is
5x² + 2x - 15 = 0
Consider the system of equations. y = −2x + 4 y = − 1/3x − 1
Hey there! I'm happy to help!
We have two values for y. Since y=y, this means that −2x + 4 and − 1/3x − 1 are equal as well, so we can put them in an equation and solve for x.
−2x + 4 = − 1/3x − 1
We subtract 4 from both sides.
-2x=-1/3x-5
We add 1/3 x to both sides.
-5/3x=-5
We divide both sides by -1 2/3.
x=3
Now, we plug this into one of the original equations to find y.
y=-2(3)+4
y=-6+4
y=-2
Therefore, the solution is (3,-2) or x=3 and y=-2.
I hope that this helps! Have a wonderful day! :D

True or false: the coordinate grid below shows the triangle transformed following the rule : (x,y)-> (x-4,y+3)
Answer: True
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
Step 1: Find the Coordinates of the Original Triangle
(2, -2)
(6, -3)
(5, 2)
Step 2: Apply the Transformation to the Coordinates
(2-(4),-2+(3)) -> (-2, 5)
(6-(4),-3+(3)) -> (2, 0)
(5-(4),2+(3)) -> (1, 5)
Step 3: Compare the points on the red triangle with the points you got
(-2, 5) = (-2, 5)
(2, 0) = (2, 0)
(1, 5) = (1, 5)
Because the coordinates are the same we can conclude that the triangle was transformed with the rule: (x,y)-> (x-4,y+3)
What is the equation of the line?A. y=3/4x−1 B.y=4/3x+1 C.y=3/4x+1 D.y=4/3x−1
Answer:
B. y = 4/3x + 1
Step-by-step explanation:
The offered choices are in slope-intercept form:
y = mx + b
where m represents the slope (rise/run) and b represents the y-intercept.
The graph crosses the y-axis at y=1, so the y-intercept is +1. That eliminates choices A and D.
The slope is greater than 1, so choice C is eliminated. You know the slope is greater than 1 because the line goes up more than 1 unit for a 1-unit change to the right. If you look where the line crosses grid points, you see that it rises 4 units for a run of 3 units to the right. That means ...
m = rise/run = 4/3
The equation is ...
y = 4/3x +1 . . . . matches choice B
Answer:
B. y = 4/3x + 1
Step-by-step explanation:
First, find the slope using rise/run (y2 - y1) / (x2 - x1)
Use the points (0, 1) and (3, 5)
Plug in the numbers:
(5 - 1) / (3 - 0)
= 4/3
Looking at the graph, we can see the y intercept is (0, 1) so we can plug in 1 into the equation y = mx + b as b:
y = mx + b
y = 4/3x + 1
Arthur, Yusuf, and Bill had some stamps in the ratio 3: 5: 6. When Yusuf gave some stamps to Arthur and Bill gave Arthur 42 stamps more than what Yusuf gave Arthur, they all had the same number of stamps each. How many stamps did Yusuf have at first?
Answer:
210 stamps
Step-by-step explanation:
Given:
Arthur ⇒ a = 3 kYusuf ⇒ y = 5kBill ⇒ b = 6kYusuf gave x stamps to Arthur, then:
y = 5k -xa = 3k + xBill gave Arthur 42 stamps more than Yusuf gave to Arthur, then:
b = 6k - (x+42)a = 3k + x + x + 42Now all 3 have same amount of stamps:
5k -x = 6k - x - 42 = 3k + 2x + 42From the first part of the equation we get:
6k - 5k = 42 + x - xk = 42How many stamps did Yusuf have at first?
y = 5k y =5*42 y = 210 stampsYusuf had 210 stamps at first

Answer:
x = 19.5, RQS=43
Step-by-step explanation:
It is important to note that RQS and TQS are supplementary, meaning their angles will add up to 180. Knowing this, we can create and solve the equation to find x..
(2x+4) + (6x+20) = 180
8x + 24 = 180
8x = 156
x = 19.5
Now that we know the value of x, we can substitute it into the equation for RQS, 2x+4.
2(19.5)+4
39+4
43
Hope this helped!
Answer:
[tex]x=19.5^o[/tex]
[tex]\angle RQS=43^o[/tex]
Step-by-step explanation:
Notice that the addition of these two angles give you and angle of [tex]180^o[/tex], therefore we can write the following equation to represent such addition:
[tex](2x+4)^o + (6x+20)^o=180^o\\2x+6x+4^o+20^o=180^o\\8\,x+24^o=180^o\\8\,x=180^o-24^o\\8\,x=156^o\\x=156^o/8\\x=19.5^o[/tex]
Therefore, the value of the angle RQS is:
[tex]\angle RQS=(2\,x+4)^o=(2\,*\,19.5^o)+4^o=43^o[/tex]

If the length of the legs of a right triangle are 18 and 34, what is the length of the hypotenuse? Round your
answer to the nearest tenth, if necessary.
Answer:
The answer is 38.5Step-by-step explanation:
Since we have been given the legs of the right angled triangle we can use Pythagoras theorem to find the hypotenuse
That's
[tex] {h}^{2} = {b}^{2} + {c}^{2} [/tex]
where
h is the hypotenuse
The legs of the triangle are 18 and 34 so the hypotenuse is
[tex] {h}^{2} = {18}^{2} + {34}^{2} [/tex]
[tex]h = \sqrt{324 + 1156} \\ h = \sqrt{1480} \\ h = 2 \sqrt{370} [/tex]
h = 38.47076
We have the final answer as
h = 38.5 to the nearest tenthHope this helps you
Answer:
38.5
Step-by-step explanation:
Hello!
To find the length of a missing side of a right triangle we use the equation
[tex]a^{2} +b^{2} =c^{2}[/tex]
a is a leg
b is the other leg
c is the hypotenuse
Put in what we know
[tex]18^{2} +34^{2}= c^{2}[/tex]
Simplify
[tex]324+1156 = c^{2}[/tex]
Simplify
[tex]1480 = c^{2}[/tex]
Take the square root of both sides
38.470 = c
Round to the nearest tenth
38.5 = c

The price of an item was reduced 25% to $30 what was the original price of the item
Answer:
$40
Step-by-step explanation:
Let the original price of the item be x.
From the first statement, the price of the item was reduced 25% to $30. This means that new price of the item is now 75% (0.75) of the original price(x), and this new price is equal to $30. i.e
0.75x = 30
Now, let's solve for x.
0.75x = 30 [divide both sides by 0.75]
[tex]\frac{0.75x}{0.75}[/tex] = [tex]\frac{30}{0.75}[/tex]
x = 40.
Therefore, the original price of the item was $40

1 way ANOVA analysis was used to test the effectiveness of 3 kinds of headache medicines (Advil, Tylenol, and Excedrin). The analysis involved 21 people (7 per group), and used an alpha level of 0.01. What is the Critical Value
Answer:
The critical region is F >F ₀.₀₁ (2,18) = 6.01
Step-by-step explanation:
For 1 way ANOVA the degrees of freedom Between Samples would 2 and within Samples would be 18 .
Alpha is given to be = 0.01
v1 = k-1 and v2 = n-k
Where k is the number of rows and n is the total number of values
v1= 3-1= 2 and v2 = 21-3= 18
So if we look up the table we find the values of the critical region to be 6.01
Hence the critical region is less and equal to 6.01
The critical region is F >F ₀.₀₁ (2,18) = 6.01

David uses drawing software to rotate the regular hexagon about its center. Through which angle measures can he rotate the hexagon to map it onto itself? Select each correct answer. 30° 45º 60° 120° 180°
Answer:
60, 120 and 180.
Step-by-step explanation:
It maps onto itself every 60 degrees.
So as they are multiples of 60 it will map onto itself at 120 and 189 degrees also.
The measure of the angle by which David can rotate the hexagon to map it onto itself is 60°, 120°, and 180°. The correct options are C, D, and E.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
Given that David uses drawing software to rotate the regular hexagon about its center. Now, since the measure of the center angle of a hexagon made by any of its sides is 60°.
Further, if the hexagon is rotated by any angle that is divisible by 60° then it will result in the same hexagon.
Hence, the measure of the angle by which David can rotate the hexagon to map it onto itself is 60°, 120°, and 180°.
