Answer:

No, Ayden is incorrect

Step-by-step explanation:

Because the last 7 is in the thousandth place so therefore he is wrong, but this would be the correct answer 54.77 since the last 7 is in the hundredth place.

Im trying to solve this but don’t understand how m-3(-5x+2)+x=42

timofeeve [1]

-3(-5x+2)+x=42
Distribute the -3 to the -5 and 2 so you would be left with
15x-6+x=42
Then you combine like terms and the x’s
16x-6=42
Add the 6 to the 42
16x=48
Then divide by 16 on both sides
X=3

I hope that helped.

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 = $\frac{1}{4} number of calls$ th

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

= 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= $\frac{3}{4} number of calls$ th

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

=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) = $\frac{1}{10} number of calls$ th

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

= 3rd term

D1= 41

D9= $\frac{9}{10} number of calls$ th

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

=27th term

D9 = 67

(d) 33rd percentile = $\frac{33}{100} number of calls$ th

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

= 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
