Answer:
4.4 but that's not rational so 4 would most likely be your answer
Step-by-step explanation:
You can't make exactly 88 dollars with a certain number of 20 dollar bills. The closest you can get is 80.
Answer: (–1)(525) and (35)(–15) are equivalent to (- 7) (-15) (- 5)
Step-by-step explanation:
Given (- 7) (-15) (- 5)
To Find : Which two expressions that are equivalent (- 7) (-15) (- 5)
(–7)(–75) and (–1)(525)
(–1)(525) and (35)(–15)
(35)(–15) and (115)(–5)
(–1)(525) and (115)(–5)
Solution:
(- 7) (-15) (- 5)
= (105)(-5)
= - 525
(–7)(–75) and (–1)(525)
= 525 & - 525
not Equal
(–1)(525) and (35)(–15)
= -525 and - 525
Both Equal to (- 7) (-15) (- 5)
(35)(–15) and (115)(–5)
= -525 and - 575
not Equal
(–1)(525) and (115)(–5)
= -525 and - 575
not Equal
(–1)(525) and (35)(–15) are equivalent to (- 7) (-15) (- 5)
The pair of expressions equivalent to (Negative 7) (Negative 15) (Negative 5) are (Negative 7) (Negative 75) and (Negative 1) (525) because both pair of expressions result in -525.
The question asks which pair of expressions are equivalent to the expression (Negative 7) (Negative 15) (Negative 5). For this, we need to remember the rule in mathematics that the multiplication of two negative numbers gives a positive result and the multiplication of three negative numbers gives a negative result.
So, (Negative 7) (Negative 15) (Negative 5) equals to -7*15*5 = -525. Now, among the given options, the pair of expressions that are equivalent to -525 are (Negative 7) (Negative 75) and (Negative 1) (525), because -7*75 also equals -525, and -1*525 equals -525 as well.
Therefore, the pairs of expressions equivalent to (Negative 7) (Negative 15) (Negative 5) are (Negative 7) (Negative 75) and (Negative 1) (525).

Sample 2 is a random sample from grades 11 and 12 and consists of the following scores: 84, 86, 87, 84, 86, 89, 90, 87, 87, 84, 86.
Choose the following statements that correctly compare the two samples.
Check all that are true.
A). Sample 2 shows 11th and 12th grade students, on average, did better.
B) . Sample 1 has a higher probability than Sample 2.
C). The measure of center is the same for both samples.
D). Sample 1 shows 9th and 10th grade students, on average, did better.
E). Sample 2 has a higher median score than Sample 1.
Answer:
E)- Sample 2 has a higher median score than Sample 1.
Step-by-step explanation:
For comparing both samples by the median, We are more clear that Sample 2 (grades of 11th and 12th) is better than Sample 1 (grades of 9th and 10th).
We didn't choose other options because neither only seeing the samples nor by measuring the probability of both samples We do a better comparison of both the samples.
Also by measuring the mean and median of the both given samples we get both Option C and D are incorrect.
