Answer:
See steps below
Step-by-step explanation:
a)
The cdf associated with f is
for 0<x<1
<h3>See picture 1
</h3>
The median is a point x such that
F(x) = ½
so, the median is
The 25th percentile equals the 1st quartile and is a point x such
F(x) = ¼
and the 25th percentile is
b)
The cdf associated with f is
for x>1
<h3>See picture 2
</h3>
The median is
The 25th percentile is
c)
f(x) = 1/3 for 0<x<1 or 2<x<4
The cdf associated with f is
for 0<x<1
for 2<x<4
<h3>See picture 3
</h3>
The median is
The 25th percentile is
2c : 3c = 60
5c = 60
c = 12
Fred will need 24 cups of peaches to make 60 cups of fruit salad.
Answer:
55.5
Step-by-step explanation:
find the median - in this case it's 60
then group the upper and lower halves of the data:
(11, 19, 35, 42) 60 (72, 80, 85, 88)
now we find the medians of those sets:
35 + 19/2 = 54/2 =27
80 + 85/2 = 165/2 = 82.5
then subtract those two medians to find the interquartile:
82.5 - 27 = 55.5
Answer:
d
Step-by-step explanation:
d
Answer:
s = 15
Step-by-step explanation:
We know that a straight line measures 180°
so… in order to find the value of s add the two angles with a sum of 180 and then solve for s
(9s + 8)° + 37° = 180°
Combine like terms
9s + 45 = 180
Subtract 45 from both sides
9s = 135
Solve for s
s = 135/9
s = 15
