PLZ DONT LEAVE IN BLANK I WILL DO ANYTHING!!!!

Mathematics
1 answer:
mafiozo [28]3 years ago
8 0

Answer:

Option 3

Step-by-step explanation:

Options numbered 1 to 4, top to bottom

Plot the scores in increasing order

20, 24, 25, 27, 29, 31, 34

The first and forth options can be eliminated because the whiskers do not cover the upper end of the range correctly. First ignores 34 and last includes 35, which is not in our score list.

The second option incorrectly places the median score at 25

The third option correctly places the median score at 27,  the lower quartile at 24, and the upper quartile at 31

Find the other endpoint of the line segment with the given endpoint and midpoint.
Shtirlitz [24]

Answer:

endpoint is (29, -13)

Step-by-step explanation:

Formula for midpoint is (\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2}  }{2} )

So, let (x_{2} , y_{2} ) be the coordinates of the endpoint you are looking for.

x_{1} = -9  and y_{1}  = 7

(\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} ) = (10, -3)

\frac{-9 + x_{2} }{2}  = 10           \frac{7 + y_{2} }{2}  = -3

-9 + x_{2} = 20         7 + y_{2}  = -6

x_{2}  =  29                    y_{2}  = -13

endpoint is (29, -13)

x=\frac{14*100}{35}=\frac{1400}{35}=40

⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ ​ b(1)=−2 b(n)=b(n−1)−7 ​ Find the 3 rd 3 rd 3, start superscript, start text, r, d, end text, end superscript ter
vitfil [10]

Answer:

-16

Step-by-step explanation:

Given the sequence:

b(n)=b(n−1)−7, where b(1)=−2

b(2)=b(2−1)−7

=b(1)−7

=-2-7

b(2)=-9

Therefore, the 3rd term of the sequence

b(3)=b(3−1)−7

=b(2)-7   (Recall b(2)=-9 from above)

=-9-7

b(3)=-16

The 3rd term of the sequence is -16.
