Olivia imported x indentical pens at a cost price of $0.50 per pen. In phase 1, she sold 70% of the pens at a price that is 10% above the cost price. In phase 2, she sold each of the remaining pens at a price that is 40% of the selling price of each pen in phase 1. In the end, she had a total loss of $49. (a)Write down an expression in terms of x, for the total amount of money collected from the sale of pens from (i) Phase 1, (ii) Phase 2. (b) Hence, by forming an equation in terms of x, find the number of pens, x, that she has imported. (c)Express her total loss as a percentage of her cost price

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.  

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract
