Answer:
I think it's B because I think there can only be one outlier. idk for sure but I think i remember learning that
Step-by-step explanation:
common denumerator is 12
-8/12x-9/12x=10/12
-17/12x=10/12 <<multiply by 12
-17x=10
x=-0.59
Sqrt=13 is not possible apply phythagoren theorm
a^2+b^2=c^2
(√2)^2+(3)^3=11
or other way is (3)^2- (√2)^2=7
The probability of picking a red marble three times in a row with replacement is:
number of red marbles divided by total number of marbles cubed...
(6/10)^3=27/125
The above is the theoretical probability...
From the chart we see that three reds in a row happened twice in twenty-five trials so the experimental probability is:
2/25
The experimental probability about 0.14 less than theoretically expected...
C)
Answer in interval notation is (-3, 1)
This is the same as saying -3 < x < 1
=====================================================
Explanation:
Since y = f(x), this means we're looking for points on the red curve such that they have a negative y coordinate. Visually, we're looking for points that are below the horizontal x axis.
These points are shown in the diagram below. I've marked the section we're after in blue. This blue section spans from x = -3 to x = 1. We exclude both endpoints because each x value leads to f(x) = 0, but we want f(x) values smaller than zero.
