Answer:
-1 and 0
Step-by-step explanation:
X ^4+x = 0;
x*(x^3+1)=0;
x*[(x^3-x)+(x+1)]=0;
x*[x(x-1)(x+1)+(x+1)]=0;
x*(x+1)(x^2-x+1)=0;
Since x^2-x+1=0 has no intersection with the X-axis, there is no x value such that y=0
x=0 or -1

Step-by-step explanation:
The median is the middle value of the data set in ascending order. If there is no exact middle then the median is the average of the values either side of the middle.
Given
3 8 14 19 22 29 33 37 43 49
↑ middle is between 22 and 29
median =
=
= 25.5
The upper quartile
is the middle value of the data to the right of the median.
29 33 37 43 49
↑
= 37
The lower quartile
is the middle value of the data to the left of the median.
3 8 14 19 22
↑
= 14
The min is the smallest value in the data set, that is 3
The max is the largest value in the data set, that is 49
The 5 number summary is
3, 14, 25.5, 37, 49
Answer:
A baseball player hit 73 home runs in a season.
Of the 73 home runs, 25 went to right field, 25 went to right center field, 8 went to center field, 10 went to left center field, and 5 went to left field.
(a) the probability that a randomly selected home run was hit to left center field =
= 13.69%
(B) Since the probability of an unusual event is 0, it was possible for this player to hit a home run to left center field.
