If x < 0 and y < 0, where is the point (x, y) located? quadrant
Answer:
quadrant 3
Step-by-step explanation:
first you have to realize how the quadrants are positioned start top right and number 1 through 4 counter clockwise.
then you have to realize the number values in the quadrants
1 (x,y) 2 (-x,y) 3(-x,-y) 4( x,-y)
x<0 and y<0 both x and y are less than zero therefor quadrant 3

Enter the number that belongs in the green box.
Answer:
x = 13
Step-by-step explanation:
First start with the blank equation
[tex]a^{2} + b^{2} = c^{2}[/tex]
Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.
[tex]5^{2} + 12^{2} = c^{2}[/tex]
Then solve
25 + 144 = [tex]c^{2}[/tex]
169 =[tex]c^{2}[/tex]
[tex]\sqrt{169} = \sqrt{c^{2} }[/tex]
c = 13

twenty-nine to the wth
power?
that's my question I dont get please help
Answer:
I would assume that there is more to this question somewhere on the paper. w seems to be the variable you have to find. Check if you have any more info near that question that would help you find the value of w, so that you can find out what 29 to the power of w is.
There should be an equation somewhere to solve for the value of w.
If that is the only information provided for that question, then it seems like a typo, I guess.

The median of Rae's data is 2.22 minutes, and the median of Doris' data is 2.14 minutes. The interquartile range for Rae is , and the interquartile range for Doris is , . The two data sets overlap
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

In a bag there are 3 red marbles, 5 white marbles, and 2 blue marbles. One marble is selected and then it is not replaced. Find the probability of selecting a white marble 3 times in a row.
Answer:
1/12
Step-by-step explanation:
In a bag, there are 3 red marbles, 5 white marbles, and 2 blue marbles. One marble is selected and then it is not replaced. Find the probability of selecting a white marble 3 times in a row.
The total number of marbles in the bag is given as:
3 red + 5 white + 2 blue
= 10 marbles
The probability of selecting a white marble 3 times in a row without replacement is calculated as:
5/10 × 4/9 × 3/8
= 60/720
= 1/12
3. A landscape plan includes a rectangular flower bed that is surrounded the wood planks. In the drawing, the rectangular flower bed is 8 in. by 12 in. The length and width of the actual flower bed will be 26 times larger than the length and width in the drawing.
(a) What is the perimeter of the drawing? Show all calculations that lead to the answer and include units.
(b) What is the perimeter of the actual flower bed? Show all calculations that lead to the answer and include units.
(c) What is the effect on the perimeter of the flower bed with the dimensions are multiplied by 26? Write the final answer in a sentence and show supporting calculations to arrive at the answer.
Answer:I dont know if this is right but
A: 384 in.
B: 1040 in. = 86 ft
C: because the dimensions are multiplied by 26 inches, the perimeter for the actual flower bed is converted into feet.
Step-by-step explanation:
A: (8*2)+(12*2) = 384 in.
B: ((8*26)*2)+((12*26)*2) = 1040 in. = 86 ft.

Answer:
(A) 8+8+12+12=
40in = 3ft 4in
(B) 8 x 26= 208
12 x 26= 312
(208 x 2) + (312 x 2) = 1040in = 86ft

Answer:
m∠a = 60°
Step-by-step explanation:
Hi there,
Before answering this question, you should know that the sum of all the angles in a triangle will always be 180°. Therefore, we can write this equation to find the value of ∠a :
70° + 50° + m∠a = 180°
Solve for m∠a
120° + m∠a = 180°
m∠a = 60°
Hope this answer helps. Cheers.

Answer:
F
Step-by-step explanation:
F doesn't represent a function because -1 and 2 have multiple outputs. A function is when an input only has one output. F is not a function.
