Answers
Answer:
1) The line AB can be renamed as BA and h
2 ) Points B, D and C are on the same line.
3) ABE is the another name given to the plane F.
4) E is another point which is not coplanar with ABC.
5) Another name for CD is g or DC
6) AB CB DB are rays with end points B
7) BC and BD are opposite rays .
8) CB or g is another name for CD
Step-by-step explanation:
1) The line AB can be renamed as BA and h
2 ) Collinear points are those points which lie on the same line. So points B, D and C are on the same line.
3) Points ABE define the plane F so ABE is the another name given to the plane F.
4) E is another point which is not coplanar with ABC. ( Coplanar points are those points which are situated on the same plane)So from the picture we see that point E lies far away from the plane of ABC.
5) Another name for CD is g or DC
6) AB CB DB are rays with end points B
7) BC and BD are opposite rays . ( A ray is a line which extends indefinitely . In simple words it has no end point. It may pass through certain points. It is represented by an arrow at one end.)
8) CB or g is another name for CD

Data sets A and B are dependent. Find sd.Assume that the paired data came from a population that is normally distributed.A. 1.73B. 1.21C. 1.32D. 1.89
Answer: A.1.73
Step-by-step explanation:
Given the data:
A : 2.7, 3.7, 5.6, 2.6, 2.7
B : 5.1, 4.0, 3.9, 3.8, 5.2
Difference betweenA and B (A - B) :
Xd = (A - B) = - 2.4, -0.3, 1.7, - 1.2, - 2.5
Sum of (A - B) = Σ Xd = (-2.4 + (-0.3) + 1.7 + (-1.2) + (-2.5) = - 4. 7
Md = ΣXd / n = - 4.7 / 5 = - 0.94
Xd - Md = (-2.4 + 0.94), (-0.3 + 0.94), (1.7 + 0.94), (-1.2 + 0.94), (-2.5 + 0.94)
(Xd - Md) = - 1.46, 0.64, 2.64, - 0.26, - 1.56
(Xd - Md)^2 = (-1.46)^2 + 0.64^2 + 2.64^2 + (-0.26)^2 + (-1.56)^2
Σ(Xd - Md)^2 = (2.1316 + 0.4096 + 6.9696 + 0.0676 + 2.4336) = 12.012
Standard deviation = √[Σ(Xd - Md)^2 / (n-1)]
Standard deviation= √12.012 / 4
Standard deviation = 1.7329
Standard deviation= 1.73

A bicycle is traveling at 20 miles per hour.
How many feet will it cover in 55 seconds?
Round your answer to the nearest tenth of a foot.
Answers
Answer:
1613.3 feetStep-by-step explanation:
Given the conversion 1mile = 5280feet
If a bicycle is traveling at 20 miles per hour, then the bicycke must have been travelling at (20*5280)feet per hour which is equivalent to 105,600 feet per hour.
To know the number of feet that will be covered in 55seconds, we will solve the equality operation;
If 105,600 feet = 1hour (3600secs)
x foot = 55secs
where x is the amount of feet it will cover in 55 seconds?
Cross multiply
3600 * x = 105,600*55
3600x = 5,808,000
divide both sides by 3600
3600x/3600 = 5,808,000/3600
x = 1613.3 feet (to the nearest tenth)
Hence the amount of feet covered in 55seconds to the nearest tenth is 1613.3 feet
a. How many ways can the letters of the word ALGORITHM be arranged in a row?
b. How many ways can the letters of the word ALGORITHM be arranged in a row if A and L must remain together (in order) as a unit?
c. How many ways can the letters of the word ALGORITHM be arranged in a row if the letters GOR must remain together (in order) as a unit?
Answers
Answer: a) 362880 b) 40320 c)720
Step-by-step explanation:
a) There are 9 letters in the word ALGORITHM. Pls note that all 9 letters are different.
So to find the number of the ways which the letters can be arranged lets imagine , that in 1st place can stay any of 9 letters, in second place any of remaining 8 letters, in 3-rd place - any of 7 letters etc
So total number of the ways is
N= 9*8*7*6*5*4*3*2*1=9!=362880
b) If A and L must remain togetherin order AL ( LA is forbidden !) so we can imagine that AL is 1 special letter.
So total number of the letters is 8. Similarly to a) we can find the number of the ways as:
N=8*7*6*5*4*3*2*1=40320
c) Similarly to b) lets imagine that GOR is 1 special letter. So there are only 7 letters . Similarly to a) the number of the ways is
N=7*6*5*4*3*2=720

An electronics store received two shipments of radios. Of the 250 radios in the first shipment, exactly 6% were damaged. In the second shipment, 4% of the radios were damaged. A total of 24 radios were damaged. How many radios in the combined shipments were NOT damaged? A. 466 B. 441 C. 451 D. 460
Answers
Answer:
Total number of not damaged = 451
C. 451
Step-by-step explanation:
In the first shipment, 6% of the 250 radios where damaged.
Number of damaged= 6/100 * 250
Number of damaged= 6*2.5
Number of damaged= 15 radios.
Number of not damaged= 250-15
Number of not damaged = 235 radios
In the second shipment, 4% of the radios were damaged
Let the number of second shipment= y
0.04 of y where damaged
Total number of radio damaged= 24
15 + 0.04y = 24
0.04y= 24-15
0.04y = 9
Y= 9/0.04
Y= 225
Number of radio in the second shipment= 225
Number of damaged in the second shipment= 0.04*225
Number of damaged in the second shipment= 9
Number of not damaged in the second shipment= 225-9
Number of damaged in the second shipment= 216
Total number of not damaged
= 235+216
= 451
Total number of not damaged= 451

(3 + 2i) + (4 – 5i) solve the equation .
Answers
Answer:
7 - 3 i
Step-by-step explanation:
Simplifying
(3 + -2i) + (4 + -5i) = 0
Remove parenthesis around (3 + -2i)
3 + -2i + (4 + -5i) = 0
Remove parenthesis around (4 + -5i)
3 + -2i + 4 + -5i = 0
Reorder the terms:
3 + 4 + -2i + -5i = 0
Combine like terms: 3 + 4 = 7
7 + -2i + -5i = 0
Combine like terms: -2i + -5i = -7i
7 + -7i = 0
Solving
7 + -7i = 0
Solving for variable 'i'.
Move all terms containing i to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + -7i = 0 + -7
Combine like terms: 7 + -7 = 0
0 + -7i = 0 + -7
-7i = 0 + -7
Combine like terms: 0 + -7 = -7
-7i = -7
Divide each side by '-7'.
i = 1
Simplifying
i = 1
A photocopy of a polygon was reduced to 70% of its original size. Then, the copy was again reduced to 70% of its size.
a.is the second photocopy similar to the original?
b.what is the ratio of the corresponding sides of the second photocopy to the original?
Answers
Step-by-step explanation:
Step 1 of 4
a) Yes, since the photo copy, is same which is reduced by 80% it remains similar. Because the angles stay the same and the ratios responding sides are proportional.
The following is the figure:

a). Photocopy of a polygon reduced the size of the original polygon by
70%.
But the shape and angles of the the polygon remains unchanged.
Therefore, all the photocopies will be similar to the original polygon.
b). Let the measure of a side of the original polygon measures 'x' unit.
Size of the original polygon gets reduced by 70% in the photocopy.
Then the measure of the side in the photocopy = x - (70% of x)
= [tex]x-\frac{70x}{100}[/tex]
= [tex]x-0.7x[/tex]
= [tex]0.3x[/tex] units
Size of the second photocopy was reduced again by 70%.
Therefore, measure of the side of the second polygon = [tex]0.3x-(\frac{70}{100}\times 0.3x)[/tex]
= [tex]0.3x-0.21x[/tex]
= [tex]0.09x[/tex] units
Ratio of the corresponding sides of the second photocopy and the
original = [tex]\frac{0.09x}{x}[/tex]
= 0.09 : 1

June bought three books. For the first book, she paid one half of her allowance plus $1 more. For the second book, she paid one half of her left-over money plus $2 more. For the third book, she paid one half of her left-over money plus $3 more. At this point, she had no money left. How much was her allowance?
Answers
Answer:
$34
Step-by-step explanation:
I'd work backwards.
For the third book, she paid all her remaining money. The problem says she paid "1/2 her leftover money + $3". This means that: (let m = money used to buy book 3)
m = 1/2m + 3
1/2m = 3
m = 6
For the second book: (let n = money before book 2)
n - m (money left after book 2) = 1/2n + 2
1/2n +2 is money used up for book, which is the same as n-m.
n = 1/2n + 2 + m
1/2n = 2 + m = 2 + 6
1/2n =8
n = 16
For the first book, she spent 1/2 her money + 1. If o = money before book 1 (or the whole allowance):
o - n = 1/2o + 1
o = 1/2o + n + 1 = 1/2o + 16 + 1
1/2o = 17
o = 34
Check!
Spent 17 (half 34) + 1 on book 1
16 left
Spent 8 (half 16) +2 on book 2
6 left
Spent 3 (half 6) + 3 on book 3
0 left
Heather wants to purchase a pet from her local pet store. The pet store is offering 50% off rare exotic parrots. The original purchase price of a parrot is $956.50. Heather has a coupon for 10% off her entire purchase. How much will she pay if she also purchases a birdcage for $47.05?
$525.66
$478.25
$472.77
$903.20
Answers
C) $472.77
Step-by-step explanation: The parrot is half off so it goes from $956.50 to $478.25. Add the bird cage for $47.05 and she has a total of $523.3 to pay. The 10% off coupon makes her need to pay $472.77.
Answer:
$472.77
Step-by-step explanation:
To to this you would just do 50% of 956.50 so you would multiply 956.50 and 50 so you get 48,725 and divide by 100 so you get 487.25 as the price of the bird. So then you you would add 47.05 to the number so you get 525.30 and you would multiply by 10 then divide by 100 so you get 52.53 and subtract that from 525.30 so you get $472.77
