Answer:
9x^2+22x-2
Step-by-step explanation:
f(g(x))=(3x+1)^2+2(3x+1)-4
=9x^2+16x+6x+2-4
=9x^2+22x-2
to find the soultion of mentioned question you have to put the value of g(x) into f(x) and then solve it like normal ...
Answer:
Step-by-step explanation:
p=4
Q=2
plot an x onto the 4 on th y line and a 2 on the x line
then draw a horizontal line with the ruler provided through 4 and 2
hope it helps :)
When we say a statistic is resistant, we mean the extreme values do not affect the statistic to a large extent or to an extent which makes a major difference. Mean and median are example of such statistics. By changing the extreme values we do not see a substantial difference in the value of mean and median for the data set.
Consider a sample: 1,2,3,4,4,5,6,7,8
The median for this data set is 4.
If we change the extreme values to get this sample: -5,2,3,4,4,5,6,7,100
The median will still be the same i.e. 4. This is what is meant by a resistant statistic.
So option a is the correct ans.
Answer:
The new vertices are:
Step-by-step explanation:
The given vertices are
Rule for reflection about x axis is →.
So, →

Now, new vertices after reflection about x axis are .
Rule for 90 degree rotation counter-clockwise is →.
So, →
→
→
→
Therefore, the new rectangle after reflection about x axis and rotated 90 degrees counter-clockwise has the following vertices:
Answer:
the probability is equal to 0.0123
Step-by-step explanation:
given,
Probability of hitting a Target by A (p)= 1/3
Probability of not hitting a Target by A (q) = 1 - 1/3
= 2/3
given, problem follows negative binomial distribution
let X be the probability of hitting the target for first time in third throw
X follow NBin. (k = 3 , p = 1/3)
=
=
= 0.0123
hence, the probability is equal to 0.0123
