Answer:
The correct option is D. Discontinuity at (1, 7), zero at (negative four thirds, 0)
Step-by-step explanation:
To find the point of discontinuity :
Put the denominator equal to 0
⇒ x - 1 = 0
⇒ x = 1
Also, if the factor (x - 1) gets cancel, then it becomes a hole rather than a asymptote , ⇒ y = 3x + 4 at x = 1
⇒ y = 7
So, Point of discontinuity : (1, 7)
And the zero is : after cancelling the factor (x - 1) put the remaining factor = 0
⇒ 3x + 4 = 0
⇒ 3x = -4
⇒ x = negative four thirds ( zero of the function)
Therefore, The correct option is D. Discontinuity at (1, 7), zero at (negative four thirds, 0)
Answer:
Step-by-step explanation:
given that the heights of women in a population follow the normal distribution with mean 64.3 and standard deviation 2.6 in.
Let X be the height of the woman
a)
i)
ii)
b) 90th percentile is 67.628
(Mean + 1.28 times std deviation)
c) Median = mean sinc enormal distribution
Median = 64.3 inches
d) P(Z>0.5) =
e) 10th percentile =60.972
Difference between 90th and 10th percentile
=
e) Each women is independent of the other.
For any woman to be taller than 67 inches is 0.1495 is constant for each women
So Y no of women taller than 67 is binomial with n =5
P(Y=1)= 0.3911
