Answer:

Question 1: The whole is divided into 3 equal parts,

Question 2: 2 out of 3 parts are shaded.

Question 3: 2/3 of the whole is shaded,

Question 4: 1/3 of the wholde is NOT shaded.

Step-by-step explanation:

Question 1: You can see on the shape there are 2 lines and is divided into 3 parts(3 pieces separated), that means it is divided into 3 parts.

Question 2: if you look on the rectangle closely, you can see that 2 of the 3 squares are shaded.

Question 3: in question 1, we know that there are 3 pieces and in question 2, we know that 2 are shaded and that means that the fraction is 2/3.

Question 4: we know that 2/3 of the squares are shaded so that means we have to subtract 1 by 2/3 so 1-2/3=1/3 and that leaves us with 1/3 of the pieces are shaded.

just olya [345]

Answer:

(a) median = 57

(b) Q1=50     Q3=63.5

(c)D1 = 41   D9=67

(d)P33= 51

Step-by-step explanation:

(a) The numbers are arranged in ascending order, and there are even number of calls. So the median will be the average of the middle terms.

middle terms are 55 and 59

Median = \frac{55+59}{2}

median= 57

(b) First quarter Q1 = \frac{1}{4} number of callsth

=\frac{1}{4} *30th

= 7.5th

so the first quarter lies in the 7.5th= (7+0.5)th term

So we multiply 0.5 by the difference of the 7th and 8th term

=0.5 *0= 0

Q1 = 50+0=50

Q3=\frac{3}{4} number of callsth

=\frac{3}{4} *30th

=22.5th = (22+0.5)th term

So we multiply 0.5 by the difference of the 22th and 23rd term

= 0.5*1=0.5

Q3= 63+0.5=63.5

(c) First decile (D1) = \frac{1}{10} number of callsth

=\frac{1}{10} *30th

= 3rd term

D1= 41

D9= \frac{9}{10} number of callsth

=\frac{9}{10} *30th

  =27th term

D9 = 67

(d) 33rd percentile =\frac{33}{100} number of callsth

=\frac{33}{100} *30th

= 9.9th term = (9 +0.9)th

Multiply 0.9 by the difference between the 9th and tenth term.

= 0.9*0 =0

P33 = 51
