Ok so here we go!
a steam and leaf plot is very simple to figure out
for example if a number was 6|4 it would equal 64
so for your first question range equals the biggest number subtracted by the smallest number so in your case it would be 28-55
which equals 27
The probability of getting 4 heads when 8 heads when 8 fair coins are tossed is...
4/8=1/2 because u have to simplify.
Answer: 50 holes
Step-by-step explanation: I find an easy way to answer questions like this is by 'dimensional analysis'....
Dimensions mins/holes and mins
mins / (mins/holes) = holes (because 'mins' cancel out)
25 mins / (6 mins/12 holes) = 300/6 holes = 50 holes
Answer:
the quotient of -30/6 and 30/ -6 are same ie. -5, because if the numerator or denominator is negative the quotient will be negative.
hope it helps!
