Answer: The proportion that will qualify is 0.0314 or 3.14%.
First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.
(128 - 141) / 7 = -1.86
Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.
Answer: it is all of them
Step-by-step explanation:
The solution of the logarithmic equation is given by the antilog. Then the value of x is 2 and 4.
<h3>What is a factorization?</h3>
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The logarithmic equation is given below.

Take antilog, then we have

Then the value of the x is 2 and 4.

<h2>Hello!</h2>
The answer is: 1.187 tablets each time (twice a day)
<h2>Why?</h2>
From the statement we know that 0.25 tablet (1/4) should be taken twice a day per 20 kg, it makes 0.5 table a day, per 20 kg.
First, we need to convert the given weight unit (pounds) to kg:

So,

A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg

Then,

So,
For a weight of 95 Kg, 2.375 tablets should be taken a day, or 1.187 tablets each time.
Have a nice day!
