Kelly invested $1,500 in the stock market on January 1
She lost 1/3 of it by the end of January or that is:
(1/3)*1500 = $500
the remaining amount is 1500 - 500 = $1,000
she lost 2/5 of the remaining amount by the end of February:
(2/5)1000 = $400
what is left is: 1000 - 400 = $600.
School A : 12/45 = 0.266 = 26.6%
school B : 15/40 = 0.375 = 37.5%
school C : 9/27 = 0.333 = 33.3%
school D : 13/32 = 0.406 = 40.6%
so ur answer is school D
Answer: The number generator is fair. It picked the approximate percentage of black socks most of the time.
Step-by-step explanation:
A dot plot is a display of dots which represents graphically a data.
Given data of a drawer contains black socks and white socks which 40% are black socks.A number generator simulates randomly selecting 10 socks from the drawer.
The display is representing the number of black socks in each trial of 10 times.
We can see for most of the trial there is no dot ;that is no black socks.
Only in 2nd to 5th trial black socks picked in approximated percentage of 40%.
⇒The number generator is fair. It picked the approximate percentage of black socks most of the time.
