Answer:
0.7208 = 72.08% probability that this whole shipment will be accepted.
Step-by-step explanation:
For each tablet, there are only two possible outcomes. Either it meets the required specifications, or it does not. The probability of a tablet meeting the required specifications is independent of any other tablet, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which  is the number of different combinations of x objects from a set of n elements, given by the following formula.
 is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
4% rate of defects
This means that 
26 tablets
This means that 
What is the probability that this whole shipment will be accepted?
Probability that at most one tablet does not meet the specifications, which is:

Thus



Then

0.7208 = 72.08% probability that this whole shipment will be accepted.

Answer: 99.51%
Step-by-step explanation:
Given : A survey found that women's heights are normally distributed.
Population mean : 
Standard deviation: 
Minimum height = 4ft. 9 in.=
Maximum height = 6ft. 2 in.=
Let x be the random variable that represent the women's height. 
z-score : 
For x=57, we have
 
For x=74, we have
 
Now, by using the standard normal distribution table, we have
The probability of women meeting the height requirement :-

Hence, the percentage of women meeting the height requirement = 99.51%
 
        
             
        
        
        
Answer:
B
Step-by-step explanation:
y =  is the equation of a horizontal line parallel to the x- axis.
 is the equation of a horizontal line parallel to the x- axis.
A line perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 6, - 9 ) with equation
x = - 6 → B
 
        
             
        
        
        
Answer:
f(-4) = -9
Step-by-step explanation:
 f(x)=2x-1
Let x = -4
 f(-4)=2*-4-1
       = -8 -1
       = -9
