1.) <span>It typically takes teachers 9 minutes longer than students to get ready for school. - The median of two data = Teachers 25 - Students 16: typically, teachers take 25 mins to get ready and students take 16 mins to get ready.
2.) </span><span>Both of the means are correct, but the reasoning is incorrect. - the mean absolute deviation for team A is 2 and for team B is 0.8. Greater mean does not signify higher mean absolute deviation.
3.) </span><span>The students tend to have fewer siblings than the teachers. - the teachers have a wide range of data and they have more siblings than the students so the first choice is the better option.
4.) </span><span>between 120 and 153 mph in race A; between 125 and 145 mph in race B - get the data from the lower whisker till the median.</span>
vans = v, buses = b, students = s
8v + 8b =312s ...eqn 1
9v + 4b = 196s ...eqn 2
divide eqn 1 by 2
4v + 4b = 156s ...eqn 3
eqn 2 - eqn 3
5v = 40s
v = 8s
subst v = 8s in eqn 2
72s + 4b = 196 s
b = 31s
answer
each van holds 8 students and each bus holds 31 students
Find the 10th term in the following arithmetic sequence if the constant being added is -12
Step-by-step explanation:
20 - 12 = 8
8 - 12 = -4
-4 - 12 = -16
So the sequence will be
20; 8; -4; -16
an = 20 - 12(n - 1)
a10 = 20 - 12(10 - 1) = -88
(3/4) : (2 1/4)p = 0
(3/4) : ((2 + 1/4))•p = 0
1.333333p = 0
p = 0
Answer:
90ft
Step-by-step explanation:
Area = Width x Length
Length = Area/Width
Length = 4500/50
Length = 90
