1).  No answer is possible until we know how many people
there are in "this class".

2).  If there are 5 choices, and only one of them is correct,
and you close your eyes and choose one of them completely
at random, then the probability of choosing the correct one is ...

                                 1 / 5  =  20% .

Which inequality represents the sentence below? The difference of a number and one and four tenths is more than nine and seventy
Marianna [84]

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,

1\dfrac{4}{10}

Nine and seventy-eight hundredths can be written as,

9\dfrac{78}{100}

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,

p-1\dfrac{4}{10} > 9\dfrac{78}{100}\\p-\dfrac{14}{10} > \dfrac{978}{100}\\p-1.4 > 9.78\\

Hence, the inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

What error did zacharias make?
qwelly [4]
The equation 0 = -2x2 5x - 3 was the quadratic formula that Zacharias used. However, he started substituting as:
Quadratic formula as x = ; substitution as x

The errors he made: he mistakenly used the negative (-) and postive (+)
      * -5 should have been 5
      * 52 should have been -52
      * both the numerator and the denominator  should have been -2 instead        of 2

Every year Ethan earns 38,428. Each year he spends 21,728 on expenses. How much money should he have left over?
PolarNik [594]

Answer:

16,700

Step-by-step explanation:

Given that,

Earning of Ethan = 38,428

Ethan spends 21,728 on expenses.

We need to find the amount of money he has left over. It can be calculated as follows :

Left money = Earning - Spent

= 38,428 - 21,728

= 16,700

So, he has left over 16,700.
