Using a calculator with the binompdf and binomcdf features, I can calculate these values. My calculator is a TI-83 plus, and the features are found under the 2nd, Vars keys (Scroll up or down until you see them).
If "exactly" is to be found, use binompdf:
binompdf(number of trials, probability of success, exactly number)
ANSWER for exactly 3: binompdf(8, 0.5, 3) = 0.21875 = 21.875%
If "at least" is to be found, use binomcdf:
binomcdf(number of trials, probability of success, at least number - 1)
ANSWER for at least 6: binomcdf(8, 1/2, 5) ≈ 0.8555 ≈ 85.55%
If "at most" is to be found, use binomcdf:
binomcdf(number of trials, probability of success, at most number)
ANSWER for at most 3: binomcdf(8, 0.5, 3) ≈ 0.3633 ≈ 36.33%
The best approach to calculating the stipulated 20% tip by means of fractions is to note that the tip is one-fifth of the total amount charged on the bill.
<h3>What is the equivalent of the 20% tip as indicated in the task content?</h3>
The percentage represented as; 20% can be expressed as a fraction.
This follows from the fact that the percentage, % symbol translates to divided by 100.
Consequently, we must note that the 20% translates to; 20/100 = 1/5.
Hence, the 20% tip is one-fifth of the total amount.

Answer:
6
Step-by-step explanation:
subtract 5 from 107 is 102
102 divided by 17 is 6
Count the number of zeros past the number 10. That is the value of M.
If the rate is 60 pounds for $6.60 and we need to convert it to a unit rate per ounce, you will think of it as $6.60 for 60 pounds instead.
Divide to get a unit rate per pound.
$0.11 per pound
To convert this to an amount per ounce Change the rate to say $0.11 per 16 ounces(this means the same).
Divide 0.11 by 16 to get 0.006875 or $0.007 or 0.7 cents per ounce. Choice D but it should say per ounce, not per pound.
