Answer: the total price change in stock is fall of 3.2 points or -3.2 points.

Step-by-step explanation:

In integers , we use positive integers to show rise in amount whereas we use negative integers to show fall .

Given: A stock price rose 2.2 points in Week 1.

i.e. +2.2 points rise.

The stock price fell 5.4 points in Week 2.

i.e. fall of -5.4. (Much greater, than it rose)

The equation to represent the total price change in stock would be

Total price change = price rose in Week 1 + price fell in Week 2.

= [+2.2 + (-5.4)] points

= 2.2 - 5.4 points [ (+)(-) = (-)]

= -3.2 points

Hence, the total price change in stock is fall of 3.2 points.

What is a possible value for the missing term of the geometric sequence? 1250 , _ , 50 , ...

statuscvo [17]

The number could be 250. The reason why is because 1250 divided by 5 = 250, and 250 divided by 5 = 5. Hope this helps you, and good luck!!

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

1) How do you find the sum of the exterior angle measures of any convex polygon?

skelet666 [1.2K]

Answer:

1) sum of all convex polygons' EXTERIOR ANGLES IS ALWAYS 360 DEGREES. If it is a triangle or even if it is a 25- gon.

2) if the polygon is regular then this means all of the sides are equal and all of the angles are equal to each other.

for example: Find the measure of an exterior angle of a REGULAR HEXAGON. so a regular hexagon has 6 sides all the same length and 6 exterior angles all the same measures. so to find the measure of 1 exterior angle you do 360 degrees /6 = 60 degrees. so an exterior angle of a regular hexagon is 60 degrees.

The closest you can get to a 2/3rds decimal is 0.66 and that goes to infinity.

It is a never ending decimal.
