Answer:
15.500000
Step-by-step explanation:
Change the divisor 0.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
46.5 ÷ 3 = 15.500000
and therefore:
4.65 ÷ 0.3 = 15.500000
Both calculated to 6 decimal places. There, I Solved It For You! :)
Answer:
a. The average daily amount of time an adult spends on the internet is different than 4.5 hours.
Step-by-step explanation:
An internet provider states that, on average, the daily amount of time an adult spends on the internet is 4.5 hours.
At the null hypothesis, it is claimed that the mean is of 4.5 hours, that is:
A sociologist studying the behaviors of internet consumers believes the average daily amount an adult spends on the internet is different than the amount stated by the internet provider.
At the alternative hypothesis, the sociologist claim, is that the mean is different of 4.5, that is:
Thus, the correct answer is given by option a.
16 = j - 3
-j = -16 - 3
-j = -19
j = 19
The answer is: [A]: " <span>−5x − 7 < −22 and −5x − 7 ≥ −3 "
______________________________________________
Explanation:
___________________________
We are the given the following compound inequality:
__________________
" </span><span>−22 > −5x − 7 ≥ −3 "
__________________________
Consider Answer choice: [A]: </span><span>−5x − 7 < −22 and −5x − 7 ≥ −3
</span><span>____________________________________________
Do both of these given in "Answer choice [A]" hold true?
______________________________________
First, does: </span>−5x − 7 < −22 hold true?
___________________________________
<span>Yes, because, in the compound inequality given:
___________________________________
</span><span>−22 > −5x − 7 ; which is another way of saying that:
</span><span> __________________
</span>−5x − 7 < −22 .
<span>____________________
Second does: </span><span> "−5x − 7 ≥ −3 " , hold true?
</span>_____________________________
Yes, because, in the compound equality given,
________________
<span>−5x − 7 ≥ −3 ; which explicitly tells us that it holds true.
</span>_________________
Thus, "Answer choice: [A]: <span>−5x − 7 < −22 and −5x − 7 ≥ −3 " is a correct answer.
___________________
There could be other correct answers, so let us examine the other answer choices:
____________________
Consider "Answer choice: [B]: </span><span>−5x − 7 > −22 and −5x − 7 ≥ −3 ;
</span>__________________________
Do EACH of these hold true in "Answer choice "B"?
_______________
First let's examine:
_________________
−5x − 7 > −22 ; Does this hold true?
_____________________
No! Because in the compound inequality given,
−5x − 7 < −22 ; so we already know that "Answer choice: [B]" is incorrect; and thus, it makes no difference whether the other part of "answer choice [B]" is correct or incorrect.
_______________________
Let us consider: "Answer choice: [C]: <span>5x > −22 and −7 ≥ −3" .
Do these hold true with respect to our given compound inequality?
____________________________________________________
No; since NEITHER one of of this 2 (two) components given are are part of our compound inequality given.
__________________________________________________
Furthermore, the particular component given: " </span>−7 ≥ −3" does not make sense. "Negative 7" is not 'greater than or equal to' "Negative 3". -7 <span>≠ -3 . Additionally, "-7" is LESS THAN—not GREATER THAN—"-3".
</span>_________________________________________________
Also, "−5x > −22" is NOT part of the compound inequality given. So, "Answer Choice: [C]: <span>−5x > −22 and −7 ≥ −3" ; is INCORRECT.
___________________________________________________
Additional note: "</span> −5x < −22" is NOT part of the compound inequality given, either.
____________________
The [incorrect] "Answer Choice: [C]: "<span>−5x > −22 and −7 ≥ −3" ; can be somewhat deceptive.
The compound inequality given:
___________________________
</span>" −22 > −5x − 7 ≥ −3 " ; should be viewed as:
_______________________________________
" −22 > (−5x − 7) ≥ −3 " ;
_____________________________________
and the term, "(−5x − 7)" should be treated as one separate term—just like the terms: "(-22)", and "(-3)".
_______________________________________________
Let us consider "Answer choice: [D]: <span>−5x − 7 < −22 and −5x − 7 ≤ −3 " .
_______________________________________________
Start with: </span>−5x − 7 < −22 . Does this hold true for our original compound inequality?
________________
Yes! (Since in our original compound inequality; "<span>−22 > −5x − 7" ;
</span> and this component of 'Answer choice: [D]' — "−5x − 7 < −22 "— is another way of saying that: "−22 > −5x − 7" (as denoted in our original compound inequality).
___________________
Now, we shall examine the second component of
'Answer choice: [D]' — "<span>−5x − 7 ≤ −3 ".
_____________________
D</span>oes this hold true for our original compound inequality?
_______________________
No! This second component given in our 'Answer choice'—is:
<span> "-5x − 7 ≤ −3" ; and in our original compound inequality:
_______________
"</span><span>−5x − 7 ≥ −3 " !
</span>________________________
As such, since one of the compounds in 'Answer choice: [D]' is incorrect;
_______________________________________________
Answer choice: [D]: "<span>−5x − 7 < −22 and −5x − 7 ≤ −3" ; is incorrect.
