Complete question :
Rae and Doris are training to swim a 200-meter freestyle race. The table lists their practice times during training camp.
Rae’s Times(minutes)-2.12, 2.01, 2.46, 2, 2.22, 2.31, 2.23
doris times(minutes)-2.32, 2.19, 2.26, 2.03, 2.11, 2.14, 2.07
The median of Raes data is(drop down box answers, 2,2.03,2.14,2.22)minutes,and the median of doris data is(drop down box answers, 2,2.03,2.14,2.22)minutes. The interquartile range for rae is(drop down box answers, 0.01,0.13,0.26,0.30), and the interquartile range for doris is(drop down box answers, 0.02,0.06,0.18,0.19). The two data sets overlap(drop down box answers,very little, a lot
Answer:
Rae's median = 2.22
Rae's IQR = 0.30
DORIS median = 2.14
Doris IQR = 0.19
Step-by-step explanation:
Given :
Rae's time :
Ordered data : 2, 2.01, 2.12, 2.22, 2.23, 2.31, 2.46
Median = 1/2(n+1)th term ; n = 7
Median = 1/2(8) = 4th term
Median = 2.22
Q1 = 1/4(8)th term
Q1 = 2nd term = 2.01
Q3 = 3/4(n + 1)th term
Q3 = 3/4(8)th term
Q3 = 6th term = 2.31
Interquartile range = Q3 - Q1 = 2.31 - 2.01 = 0.30
DORIS Data:
Ordered data: 2.03, 2.07, 2.11, 2.14, 2.19, 2.26, 2.32
Median = 1/2(n+1)th term ; n = 7
Median = 1/2(8) = 4th term
Median = 2.14
Q1 = 1/4(8)th term
Q1 = 2nd term = 2.07
Q3 = 3/4(n + 1)th term
Q3 = 3/4(8)th term
Q3 = 6th term = 2.26
Interquartile range = Q3 - Q1 = 2.26 - 2.07 = 0.19
HELP ASAP I DONT UNDERSTAND THIS QUESTION AND WILL REALLY APPRECIATE IT AND ITS A BIG PART OF MY GRADE PLEASE AND TY I WILL ALSO MARK YOU BRAINLIST ONCE YOU HELP AND EXPLAIN A BUT HAVE A GREAT DAY EVERYONE!!!
Answer:
10 * 2w or 2(5*w)
Step-by-step explanation:
2(5*w) = (2*5) * (2*w) = 10 * 2w
2 come from double and you have to double the area. SO, 10 * 2w or 2(5*w).
Hopefully, it helps you.
Answer:
20w
Step-by-step explanation:
it is 5 feet long and w feet wide.
Doubling the length and width gives us 10 and 2w.
To find area we need to multiply the length and width.
10 times 2w is 20w.

Answer:
245
Step-by-step explanation:
25 ÷ 5 = 5
5 × 3 = 15
100 - 25 = 75
75 × 3 = 225
225 + 5 = 230
230 + 15 = 245
245
Which of the following describes the symmetry of this conic section?
Answer:
x=1
Step-by-step explanation:
It will be x=1 because once it is at x=1, the parobola is split into 2 EQUAL parts. For example, if you graph this on paper and try to guess the middle and place a line where you want to split it, the line will go at x=1
Thank you :)

6x-3y if x = 5 and y = -1
Expression: 6x - 3y
x = 5y = -1Solution: If we substitute the values of x and y into the problem, we get 6(5) - 3(-1); 6 times 5 is 30, and 3 times -1 is -3... 30 - (-3) becomes 30 + 3 = 33!!

No Solution, One Solution, or Infinitely
Answer:
Infinitely
Step-by-step explanation:
Hi,
Both sides of the equation are equal to each other, this means they're the exact same line and overlap. This is infinitely many solutions.
Hope this helps :)
Answer:
Infinitely
Step-by-step explanation:
-6p+7=7-6p can be reshuffled to read: -6p+7=-6+7. Both sides of the equation are the same, so there are infinite solutions.

Connor took a taxi from his house to the airport. The taxi company charged a pick up fee of $2.10 plus $1.75 per mile. The total fare was $12.60, not including the tip. Write and solve an equation which can be used to determine m, the number of miles in the taxi ride
9514 1404 393
Answer:
m = 6 miles in the taxi ride
Step-by-step explanation:
The total fare is ...
fare = pick-up fee + (cost per mile)×(miles)
12.60 = 2.10 + 1.75m . . . . . the equation
10.50 = 1.75m . . . . . . subtract 2.10
10.50/1.75 = m = 6 . . . . . . divide by the coefficient of m
The taxi ride was 6 miles.

Answer:
Step-by-step explanation:
Law of Sines recall Sin(A) /a = Sin(B) /b
does the above make sense?
Next we need to find the angle of A
notice that 16+75=91 :o
so angle A is only 89° ..(b/c all the way around then inside of a triangle is 180) so this is NOT a right triangle but that's okay, b/c law of sines still works fine.
then we want to find length of line AB
and if 89 = A then a = BC
and if 75 = B the b = AB (note that in the given triangle this is angle C, i'm using B , b/c you can see the difference between capital B and lower case b much easier than you can with C, & c :/ )
capitals are the angles while lower case are the length of the sides
then
Sin(89) / 29 = Sin(75) / b
solve the parts that can be put into numbers or solve for 'b' first, that means isolate 'b' all by itself on one side of the equal sign .
0.034477 = 0.965925/ b
b = 0.965925 / 0.034477
b = 28.0165
b = 28.0 ( to the nearest 10th)
we have the parts to plug in now
Sin(75) /

2. The measure of an interior angle of a regular polygon is 160 degrees. Find the number of sides in the
polygon
Answer:
18 sides
Step-by-step explanation:
(N x 180) - 360 = 160N
180N -360 = 160N
20N = 360
N = 18
Proof:
(18 x 180) -360 = 2880 total degrees
2880/18 sides = 160°
How many solutions does the system of linear equations have? Choose the best answer.
2x + 4y = 3
2x + 4y = 9
Answer:
The system of linear equations will have infinite solutions.
Step-by-step explanation:
This is because, this system of linear equations is in 2 variables, x & y. Any number can be substituted in their place. So, infinite solutions can be made.

Help me with this!! NO FAKE ANSWERS!!
Answer:
Step-by-step explanation:
this is a similar triangle, so the side that is 6 and 18 will have the same ratio as the side 4 and x, then
6/18 = 4 / x
x = 4 * 18/6
x = 2 * 18 / 3
x = 36 /3
x = 12
