In math class, Mrs. Carlton picks a student to write a homework problem on the board. The probabilities that given students will
be selected are shown below.
P(Brad) = 0.64
P(Emily) = 0.01
P(Steven) = 0.04
P(Sarah) = 0.31
Which statements are true? Choose all that are correct.

Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The population proportion is
The mean of the sampling distribution is
The sample size is n = 600
Generally the standard deviation is mathematically represented as
=>
=>
Generally the probability that the proportion of airborne viruses in a sample of 600 viruses would differ from the population proportion by greater than 3% is mathematically represented as
=>
Now add p to both side of the inequality
=>
=>
Now converting the probabilities to their respective standardized score
=>
=>
=>
From the z-table
and
So
=>
Answer:
or simplified would be
Step-by-step explanation:
In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...
rate of change
rate of change
= rate of change
Therefore, we can see that the rate of change of the diver is or simplified would be
