1. Which of the following sets of integers is arranged in order from LEAST to GREATEST?
Oi-1.5 - 9
O (1. - 5. - 10)
O (12. - 8,0)
O { - 13. - 12,9)
Answers
Answer:
Last option:
(-13, -12, 9)
Step-by-step explanation:
Here you need to look at a number line.
(an infinite line with the zero in the middle, at the left we have the negative numbers which increase to the left, and at the right, we have the positive numbers that increase to the right)
for any two pair of numbers in the number line, the number at the right is larger than the number at the left.
So for example, -10 is at the left of -3
Then:
-10 < -3.
Then a set is ordered from least to greatest if:
first we have the largest negative numbers
then the smaller negative numbers
then the zero (if there is a zero)
then the smaller positive numbers
then the largest positive numbers.
The only set that meets this condition is the last one:
(-13, -12, 9)
Why the others not meet this condition?
in the first one we have -9 after 5, and we know that -9 < 5
in the second one we actually have an order from greatest to least.
in the third one we have -8 at the right of 12, and we know that -8 < 12

At a casino, people line up to pay $20 each to be a contestant in the follow- ing game: The contestant flips a fair coin repeatedly. If she flips heads 20 times in 20 mil a row, she walks away with lion dollars; otherwise she walks away with R 0 dollars
(a) Find the PMF of R, the reward earned by the contestant.
(b) The casino counts "losing contestants who fail to win the 20 million dollar prize. Let L equal the number of los- ing contestants before the first winning contestant. What is the PMF of L?
(c) Why does the casino offer this game?
Answers
Answer:
a)
P ( R = 20 million ) = 0.00000095367
P ( R = 0 million ) i.e. not winning = 0.99999904633
b) P ( L ) = ( 1 - p )^l * p
C)The casino offer the game because the expected revenue exceeds the winning
Step-by-step explanation:
P( winning ) = P ( getting 20heads in a row ) = 0.5^20 = 0.00000095367
a) PMF of R
P ( R = 20 million ) = 0.00000095367
P ( R = 0 million ) i.e. not winning = 0.99999904633
b) what is the PMF of L
L = number of loosing clients before winning
P( L = 0 ) = P i.e. if first contestant wins, if the second contestant win, L=1 repeat same process continuously
P ( L = 2 ) = ( 1 - p)^2 p
Hence the PMF of L
P ( L ) = ( 1 - p )^l * p where p = 0.5^20
C) The casino offer the game because the expected revenue exceeds the winning
we can prove this using the relation below
E( L ) = ( 1 - P ) / 1 - ( 1 - P )
= 1 / P - 1
where p = 0.00000095367 ( probability of winning )
Hence E ( L ) = 1048575
hence expected revenue before someone wins
= (1048575 + 1 ) * 20 = $20,971,520

A department store buys 400 shirts at a cost of $9,600 and sells them at a selling price of $30 each.
Find the percent markup.
The percent markup is
%. (Round to the nearest whole number as needed.)
Answers
Answer:
The percent markup is 25%.
Step-by-step explanation:
Percent markup:
The percent markup is given by the difference in selling price and buying price multiplied by 100% and divided by the buying price.
A department store buys 400 shirts at a cost of $9,600
This means that the buying price is:
$9600/400 = $24
Find the percent markup.
Buying price: $24
Selling price: $30
30 - 24 = 6
6*100%/24 = 25%
The percent markup is 25%.

Maryam has a coupon for 33% off her entire meal of 232.88 what is the discount.
help!
Answers
Answer:
$156.03
Step-by-step explanation:
33% = 33/100 = 0.33
First, multiply the total cost with 0.33:
232.88 x 0.33 = ~76.85 (round).
Subtract 76.85 from the original cost ($232.88):
232.88 - 76.85 = 156.03
Maryam's meal will cost $156.03 after the discount.

A sales manager wanted to determine if increasing sales commissions by 5% would increase employee satisfaction. Her analyst determined the p-value was 0.04. (Use α = 0.05.)
Based on the above output, what is the correct conclusion for the Wilcoxon Signed Rank Test?
a. We do not have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
b. We do not have evidence that there is a difference in sample median employee satisfaction rating before and after the commission change.
c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
d. We have evidence that there is a difference in sample median employee satisfaction rating before and after the commission change.
Answers
Answer:
c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
Step-by-step explanation:
Pvalue is less than the alpha-level:
If the pvalue is less than the alpha-level, we have that there is sufficient evidence of the hypothesis for the population mean/median/standard deviation we are testing.
In this question:
Pvalue less than the alpha-level, so there is evidence that there is a difference in the population median. This means that the correct answer is given by option C.
The correct conclusion is: c. We have evidence that there is a difference in population median employee satisfaction rating before and after the commission change.
The given parameters are:
[tex]\mathbf{p = 0.04}[/tex] --- the p-value
[tex]\mathbf{\alpha = 0.05}[/tex] --- the significance value or the alpha level
From the options, we understand that the test parameter is the population median
By comparison, the p-value (0.04) is less than the alpha level (0.05)
When the p-value is less than the alpha-level, then it means that there is enough evidence of the hypothesis for the population parameter that is being tested.
Since the p-value is less than the alpha level, then it means that there is enough evidence to show the difference in the population median.
Hence, option (c) is correct

find the missing length?
Answers
Answer:
16
Step-by-step explanation:
If triangle GFE is similar to triangle RST, using the similarity theorem
RS/RT = GF/EF
Using pythagoras theorem;
RT² = 10² - 6²
RT² =100 - 36
RT² = 64
RT = √64
RT = 8
Recall that RS/RT = GF/EF
10/8 = 20/EF
Cross multiply
10EF = 8 * 20
10EF = 160
EF = 160/10
EF = 16
Hence the missing length is 16

Answers
Answer:
x^2+y^2=6^2
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
where h is the x coordinate of the center, k is the y coordinate of the center, and r is the radius of the circle.
We can see the center is on 0,0, and the radius is 6, so our equation is
(x-0)^2+(y-0)^2=6^2
or
x^2+y^2=6^2
Answer:
[tex] x ^2 + y^2 = 36 [/tex]
Step-by-step explanation:
Center of the circle (h, k) =(0, 0)
Radius of the circle (r) = 6 units
Equation of circle in center radius form is given as:
[tex] (x-h) ^2 + (y-k) ^2 = r^2 [/tex]
[tex] (x-0) ^2 + (y-0) ^2 = (6)^2 [/tex]
[tex] x ^2 + y^2 = 36 [/tex]
