Complete Question
The complete question is shown on the first uploaded image
Answer:
The value is [tex]z = \pm 1.645[/tex]
Step-by-step explanation:
From the question we are told that
The number of observation is greater than 50 i.e. n > 50
The level of significance is [tex]\alpha = 0.1[/tex]
Generally given that n > 30 then we will make use of the z table
So
From the z table the critical value corresponding to the level of significance level for a two-tailed test is
[tex]z = \pm 1.645[/tex]

Select all input values for which g(x) = 8.
Choose all answers that apply
A. x=-4
B. x=6
C. x=9
D. None of the above
Answer: A & C
Step-by-step explanation:
g(x) = 8 means where is y = 8?
when we go to -4 on the x-axis, the y value there is 8. so this works!
when we go to 6 on the x-axis, the y value is 6. we were looking for 8. so this does not work.
when we go to 9 on the x-axis, the y value is 8. so this works!

john ate 40% of the candies in the bag. If John ate 20 candies, how many candies were there total in the bag?
Answer:
50 candies
Step-by-step explanation:
20/whole = 40%/100%
you divide 40 by 2 to get 20
so you will do the same with the 100
100 divided by 2 is 50
Therefore, your answer is 50 candies

9 is 37 1/2% of what
Answer: 24. 9 is 37.5% of 24. You can see this by dividing 9 by 24 to get 0.375 or dividing 9 by 0.375 to get 24.
Step-by-step explanation:
Some number X, multiplied by 0.375 will equal 9, so 9 divided by .375 equals 24.
Remember percent just means per 100, so 37.5/100 is 0.375

In a lottery game, a player picks six numbers from 1 to 22. If the player matches all six numbers, they win 20,000 dollars. Otherwise, they lose $1.
What is the expected value of this game?
Answer:
Total possible number of outcomes = C(24,6) [24 choose 6]
=24!/(6!18!)
= 134596
Out of which there is only one winning combination.
Therefore we conclude:
P(win 20000)=1/134596
P(lose 1)=134595/134596
and hence the expected value is:
20000*(1/134596)+(-1)*(134595/134596)
=-114595/134596
=-0.8514 (rounded to four places after decimal)

At the neighborhood block party, Camille served 1/2 of a gallon of hot chocolate and 1/3 of a gallon of apple cider. How much more hot chocolate than apple cider did Camille serve?
Write your answer as a fraction or as a whole or mixed number.
Answer:
1/6 more hot chocolate than apple cider.
Step-by-step explanation:
In order to complete this, you first have to make both numbers have the same denominator.
2: 2, 4, 6
3: 3, 6
The new denominator is 6.
1/2 - 3/6
1/3 - 2/6
These are the new fractions after making the numbers have common denominators.
3/6 - 2/6 = 1/6
Camille serves 1/6 more hot chocolate than apple cider.

[tex]e^4^x -4=1[/tex]
(a) State the exact answer for x.
(b) State the approximate answer for x rounded to 4 decimal places.
WILL MARK BRAINLIEST IF YOU SHOW ALL WORK
It looks like you tried to write
e^4^x
which I would interpret as either
[tex]e^{4^x}[/tex] (so the exponent on e is 4ˣ )
or
[tex]e^{4x}[/tex] (so the exponent on e is 4x )
as it's shown in the question body.
If you meant the first case,
[tex]e^{4^x}-4=1[/tex]
[tex]e^{4^x}=5[/tex]
[tex]\ln\left(e^{4^x}\right)=\ln(5)[/tex]
[tex]4^x\ln(e)=\ln(5)[/tex]
[tex]4^x=\ln(5)[/tex]
[tex]\log_4\left(4^x\right)=\log_4\left(\ln(5)\right)[/tex]
[tex]x\log_4(4)=\log_4\left(\ln(5)\right)[/tex]
[tex]\boxed{x=\log_4\left(\ln(5)\right)}\approx0.3433[/tex]
If you meant the second case,
[tex]e^{4x}-4=1[/tex]
[tex]e^{4x}=5[/tex]
[tex]\ln\left(e^{4x}\right)=\ln(5)[/tex]
[tex]4x\ln(e)=\ln(5)[/tex]
[tex]4x=\ln(5)[/tex]
[tex]\boxed{x=\dfrac{\ln(5)}4\approx0.4024}[/tex]
