Does the median or mean better represent the data? And why? {20,28,35,40,132}
Answers
20,28,35,40,132
So 35 is the median
and the mean is 20 + 28 + 35 + 132 + 40 = 255 / 5 = 51
the mean is a better way to represent the data because it does not just pick a number from the set of numbers it calculates the average

Find the area of a triangle bounded by the y-axis, the line
f(x) = 34 − 4 x,
and the line perpendicular to "f" that passes through the origin.
Answers
A drawing of the triangle is attached.
We first plot the y-intercept of the line given to us, f(x)=34-4x. This is in the form f(x)=mx+b, so the y-intercept, b, is 34.
Next we use the slope to find the next points of the line. The slope is -4, which can be written as -4/1 (rise/run). This means from the y-intercept, we go down 4 and over 1 to plot the next point, and continue in this manner. We now have the y-axis and this line drawn.
Next we use the slope of the line to find the slope of the perpendicular line described. Two lines are perpendicular if their slopes are negative reciprocals of each other. The slope of the first line was -4/1; this means the slope of this line must be 1/4. We also know this point goes through the origin, so 0 is the y-intercept, and we have the equation f(x)=1/4x+0.
To graph this, plot a point at 0, the y-intercept. The slope is 1/4, so we go up 1 and over 4 to the next point. This happens to be on the line we previously drew.
To find the area of this triangle, we need to identify the base and height. The height will be perpendicular to the base. The two sides that form a right angle are the bottom and the right hand side, so the bottom is the base and the right hand side is the height.
Now we find the length of each of these sides using the distance formula. For the height:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}=\sqrt{(34-1)^2+(0-4)^2} \\ \\=\sqrt{33^2+(-4)^2}=\sqrt{1089+16}=\sqrt{1105}\approx33.24[/tex]
To find the length of the base:
[tex]d=\sqrt{(0-1)^2+(0-4)^2}=\sqrt{(-1)^2+(-4)^2}=\sqrt{1+16}=\sqrt{17} \\ \\\approx4.12[/tex]
The area of a triangle is given by A=1/2bh:

A mirror frame in the shape of an oval is shown below. The ends of the frame form semicircles: An oval is formed by a rectangle with semicircles at each end. The length of the rectangle is 54 inches. The width of the rectangle is 27 inches. Which of the following is the perimeter of the inner edge of the frame? (π = 3.14) 192.78 inches 246.78 inches 277.56 inches 331.56 inches
Answers
Answer:
The answer is 192.78 inches
Step-by-step explanation:
An oval is formed by a rectangle with semicircles at each end. We can visualize this easily.
The length of the rectangle is 54 inches.
The width of the rectangle is 27 inches.
The perimeter of rectangle is = [tex]2(L+W)[/tex]
= [tex]2(54+27)[/tex]
= 162 inches
And because there are two semicircles, we can combine them to form a circle. So, perimeter of a circle is called a circumference.
The width of the rectangle forms the diameter, so its half will be the radius.
r = [tex]\frac{27}{2}=13.5[/tex]
The circumference is given by : [tex]2\pi r[/tex]
= [tex]2\times3.14\times13.5=84.78[/tex] inches
Now as the described oval shape is a complete figure without lines inside, we will subtract the width of both sides of the rectangle from the complete perimeter.
The complete perimeter is = [tex]162+84.78=246.78[/tex] inches
The inner edge perimeter will be = [tex]246.68-2(27)[/tex] = 192.78 inches

How do you find the area of this compound shape?
Answers
the radius of the circle is 3 yards, so the diameter would be 6 yards diameter = 2 x radius)
the diameter of the circle is also the base of the triangle.
the height f the triangle is 5 yards formula for area of a triangle is 1/2 x b x h
so you have 1/2 x 6 x 5 = 15 square yards
the area for a circle is PI x r^2
so you have 3.14 x 3^2 = 28.26 for the full circle so divide this by 2 for the half circle:
area of half circle = 28.26 / 2 = 14.13 square yards
now add the area of the triangle and half circle together:
14.13 + 15 = 29.13 square yards

Now, let's get them all to a common denominator. 20 is the best choice.
You can use proportions to work this out.
[tex] \frac{7}{10} = \frac{14}{20} [/tex]
We just doubled the bottom; what you do to the bottom, you must do to the top.
[tex] \frac{8}{10} = \frac{16}{20}[/tex]
Once again we doubled the bottom, so we doubled the top as well.
[tex] \frac{3}{4} = \frac{15}{20} [/tex]
We multiplied the denominator by 5 to get it to 20. In order to keep it the same fraction, you must multiply the numerator by 5 as well.
Abra was the best shooter with [tex] \frac{8}{10} [/tex] of her free throws made.

Answers
Base Area = 36cm^2
Lateral Face Area = 48cm^2
*If this is a quadrilateral pyramid, then it has 4 lateral faces, so just multiply the "one" lateral face by 4.
Lateral Area (AL) = 4 x Lateral Face Area
-> AL = 4 x 48 = 192 cm^2
So:
SA = Ab + AL
-> SA = 36 + 192

Kamila has two number cubes each labeled 1 to 6. She is going to conduct an experiment by tossing both cubes a total of 150 times. She will find the sum of the two numbers in each role
a. Possible outcomes? __________
b. Probability of tossing a sum of six? _________
c. How many times should Kamila toss a sum of 7? _________
d. How many times should Kamila toss a sum of 10 or greater? _______
Answers
b) The probability of a sum of 6 is 5/36.
c) She should roll a sum of 7 45 times.
d) She should roll a sum of 10 45 times.
Explanation
a) There are 6 outcomes for the first die and 6 outcomes for the second one. By the fundamental counting principle, there are 6*6 = 36 outcomes for both dice together.
b) The ways to get a sum of 6 are:
1&5; 2&4; 3&3; 4&2; 5&1. There are 5 possibilities out of a total of 36, or 5/36.
c) The ways to get a sum of 7 are:
1&6; 2&5; 3&4; 4&3; 5&2; 6&1. There are 6 out of 36, or 6/36=1/6. Since she is rolling the dice 150 times, she should get a sum of 6
1/6(150) = 150/6 = 45 times.
d) The ways to get a sum of 10 or more are:
4&6; 5&5; 6&4; 5&6; 6&5; 6&6
There are 6 ways out of 36, or 6/36 = 1/6. Since she is rolling the dice 150 times, she should get a sum of 10 or more
1/6(150) = 150/6 = 45 times.
Answer:
Step-by-step explanation:
a) When two number cubes are thrown possible outcomes are
[tex]6x6 =36[/tex]
b) Probability of tossing a sum of 6
Favourable outcomes = (1,5)(5,1)(2,4) (4,2) (3,3)
Hence probability =[tex]\frac{5}{36}[/tex]
c) For getting 7 favourable outcomes are
(1,6)(2,5)(3,4)(4,3)(5,2)(6,1)
i.e one out of 6 chances.
Hence in 150 times Kamala should toss a sum of 7 --- [tex]\frac{1}{6} *150 =25[/tex]
d) Favourable outcomes for sum of 10 or greater
= (4,6) (6,4) (5,5) (5,6)(6,5)(6,6)
Probability for getting sum of 10 or greater = [tex]\frac{6}{36} =\frac{1}{6}[/tex]
No of times Kamila should toss 10 or greater
= [tex]\frac{150}{6} =25[/tex]
A fisherman borrowed 85,000 over 25 years at 13.5% p.a. interest compounded monthly. At the end of the seventh year, interest rate climbed to 15% p.a. compound and fisherman's repayments were increased to allow him to complete the repayments by the end of 25 years term.
a. how much did the fisherman owe at the end of the first 7 years?
b. what were his monthly repayments for remaining 18 years?
c. how much interests in total did the fisherman pay at the end of the 25 years long.
Answers
Rate, i, for the first 7 years = 13.5% = 0.135
Rate, i, for the remaining 18 years = 15% = 0.15
Part (a): Amount owed after 7 years
Without interest rate, monthly payment, Po= 85,000/(12*25) = 283.33
After 7 years, principal amount remaining = 85,000 - (283.33*7*12) = 61,200.
Therefore, the amount owed after 7 years, A2 = 61,200
Part (b): Monthly repayment for the rest of 18 years
Rate, i = 15% = 0.15
Monthly payment, P(18) = A1*D2
D2 = {0.15/12}/{1-(1+0.15/12)^-12*25} = 0.01281
Then,
P(18) = 85,000*0.01281 = 1088.71
Part (c): Total interest paid
I =[ I(7) + I(18)] - A1
I(7) = P(7)*7*12 + P(18)*18*12
Now, P(7) = A1*D1
D1 = {0.135/12}/{1-(1+0.115/12)^-12*25} = 0.01165
Then,
P(7) = 85,000*0.01165 = 990.25
Therefore,
I = [990.25*7*12 + 1088.71*18*12] -85,000 = 318,341.50 -85,000 = 233,341.50

What is Rational Number?
Numbers that may be expressed in the form p/q, where p and q are integers and q0, are considered rational numbers. Because fractions cannot have a negative numerator or denominator, they differ from rational numbers in this respect. Because of this, the numerator and denominator of a fraction are whole numbers (denominator 0), unlike in the case of rational numbers, when they are both integers.
So to convert a fractional to reduce form we have to divide by 10 to power how many digits thereafter decimal point, and make sure that numerator or denominator doesn't have common divisible.
.3 = 3/10
.125 = 125/1000 = 1/8
.16 = 16/100 = 4/25
.1 = 1/10
.6 = 6/10 = 3/5
.2 = 2/10 = 1/5
.75 = 75/100 = 3/4
Hence the answers will be 3/10, 1/8, 4/25, 1/10, 3/5, 1/5 and 3/4 in the rational p/q form.
