Answer:
E(x) = 7.05
Step-by-step explanation:
We are given the following information in the question:
x: 1 2 4 8 16
p(x): 0.05 0.10 0.30 0.40 0.15
Formula:
Hence, the expectation of the given data is 7.05
Answer:
130 cents per minute
Step-by-step explanation:
Convert dollars to cents.
Note that 1$ = 100 cents.
Note that 1 hour = 60 minutes.
Using Dimensional Analysis would be a great way to approach this question and see how each of the units convert.
(78 $/1 hr) ( 1 hr / 60 min ) ( 100 cents / 1 $)
= 130 cents per minute.
Answer:
10 units and 157.84 units
Step-by-step explanation:
4
substitute t = 1 into the equation
h = - 16(1)² + 6 = - 16 + 6 = - 10
the value is negative since the ball travels down
the ball has travelled 10 units after 1 second
5
substitute t = 3.2 into the equation
h = - 16(3.2)² + 6 = - 16(10.24) + 6 = - 163.84 + 6 = - 157.84
the well is 157.84 units deep
Here we are given that C is between A and B.
So using the midpoint rule, sum of whole length AB will be addition of lengths AC and BC
so we can say that option C. CA is the correct choice as it satisfies the given condition.
