Which question are you talking about?
Answer:
Step-by-step explanation:
arranging in ascending order
6,7,9,13,15,16
mean=(6+7+9+13+15+16)/6=66/6=11
number of terms=6
median=(3rd term+4th term)/2=(9+13)/2=22/2=11
range=6,7,9,13,15,16
Answer:
13.89 to 2 dec places.
Step-by-step explanation:
a7 / a5 = r^2 where r is the common ratio.
So 3/5 = r^2
r^2 = 0.6
r = +√0.6
r = 0.7746.
The first term is a5 / r^4
= 5 / (0.7746)^4
= 13.89.
1 yard is 36 inches
so 5 yards are 180 inches
1 hour is 60 minutes
so in 60 minutes she paints 180 inches
or in 1 minute she paints 3 inches
