Step-by-step explanation:
The population std. dev of the dog weight=8
Calculating the payout w s.t:
therefore, we assume that the weight of the dog is a normal distribution with std. deviation that is 8.
Answer:

Step-by-step explanation:
We are given that
Equation of curves


Both curves lie on S.
We have to find the equation of tangent plane at P(4,1,4).


Hence, t=0 and u then it satisfied the given point.
Substitute the values in the derivatives


The equation of tangent at point P(4,1,4) is given by




Answer:
a. The probability of both balls are blue is
.
b. The probability of getting first red and second yellow ball is
.
Step-by-step explanation:
It is given that the box contains 14 red balls,12 blue balls,and 9 yellow balls. The total number of balls is

The probability is defined as

Probability of getting red ball = 
Probability of getting blue ball = 
Probability of getting yellow ball = 
It is given that a ball is drawn at random and the color is noted and then put back inside the box. It means first event will not effect the probability of second event.
a.
The probability of both balls are blue is

b.
The probability of getting first red and second yellow ball is
