The inequality represents the sentence below is that the p minus 1. 4 greater-than 9.
<h3>What is the inequality equation?</h3>Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
Given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.
Before solving it, first let's discuss the tenth and hundredths,
- Tenth is written as the fractional part of the number 10. The value of one tenth is equal to 1/10 or 0.1.
- Hundredths is written as the fractional part of the number 100. The value of one hundredth is equal to 1/100 or 0.01.
Here, the sentence given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.
One and four tenths can be written as,
Nine and seventy-eight hundredths can be written as,
Let suppose the number is <em>p</em>. This difference of this number and one four tenths is more than nine and seventy-eight hundredths. Thus,
Hence, the inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

Solution :
a). The probability that the student will the 1st question after the 4th attempt.
P (correct in the 4th attempt)
=
= 0.01171875
b). The probability that the student will 3 questions after 10 total attempts.
P( X = 3) for X = B in (n = 10, p = 0.75)
=
= 0.0031
c). The mean and the standard deviation for the number of attempts up to when the students gets all the questions correct is :
There are = 6 success, p = 0.75.
Therefore, this is a case of a negative binomial distribution.
= 8
So,
= 1.6330
