Answer:
For a continuous random variable X, P(20 ≤ X ≤ 40) = 0.15 and P(X > 40) = 0.16.
Step-by-step explanation:
Here, P(x > 40) = 0.16
a). P(x < 40) = 1 - P(x > 40)
= 1 - 0.16
= 0.84
b). P(x < 20) = 1 -
= 1 - {P(20 ≤ X ≤ 40) + P(X > 40)}
= 1 - (0.15 + 0.16 )
= 1 - 0.31
= 0. 69
c). P(x = 40) = 0; The probability that a continuous variable assume a particular value is zero.
Answer:
30 units.
Step-by-step explanation:
Let x be number of milk units sold.
It has been given that You begin the week with 20 units of milk. You purchase 40 units. Therefore, total units of milk will be units.
It has been given that your ending inventory for the week is 30 units, which means after selling x units from 60 units you are left with 30 units.
We can set this information in an equation as:
Therefore, you have sold 30 units.
Answer: 95 mm Hg
Step-by-step explanation:
Given: The equation represents the linear model for the data is
Since, age is an independent quantity whereas blood pressure is dependent quantity.
Thus, y represents the the systolic blood pressure of people of several different ages (x).
Now, the age of new born baby =0
Substitute x=0 in the equation , we get y=95
Hence, The systolic blood pressure of new born baby = 95 mm hg
