Alison Bender works for an accounting firm. To make sure her work does not contain errors, her manager randomly checks on her work. Alison recently filled out 12 income tax returns for the company's clients. Unknown to anyone, two of these 12 returns have minor errors. Alison's manager randomly selects three returns from these 12 returns. Find the probability that (a) Fewer than 2 of them contains errors
Answer:
Alison Bender and Income Tax Returns
The probability that fewer than 2 of the returns contains errors is:
8.333%
Step-by-step explanation:
a) Data and Calculations:
Number of income tax returns filed by Alison = 12
Number of returns with minor errors = 2
Percentage of returns with minor errors = 2/12 = 16.67%
Random sampling of returns by Alison's manager = 3/12 = 25%
Fewer than 2 = 1
The probability of 1 error in 12 returns = 1/12 = 0.08333
= 8.333%
b) Since Alison's manager randomly selects three returns from the 12 to check for errors, the probability of discovering the errors is 25% (3/12). However, the probability that less than 2 contains errors = 8.333% (1/12).
write 5/6 - 7/9 in simplest form
9514 1404 393
Answer:
1/18
Step-by-step explanation:
18 is a suitable denominator for both fractions:
5/6 = 15/18
7/9 = 14/18
Then the difference is ...
5/6 -7/9 = 15/18 -14/18 = (15 -14)/18 = 1/18

Step-by-step explanation:
Solve for g: 19 > 2(g + 7.9).
Answer: g < 1 3/5
Step-by-step explanation:
first, i removed the parentheses.
19 > 2g + 15.8
then, i moved the terms.
-2g > 15.8 - 19
the, i calculated that.
-2g > -3.2
finally, i divided both sides.
g < 1.6
the alternative form is g < 1 3/5

Answer:
0.20 × 65 is what you would do for the second
Step-by-step explanation:
btw listen to yungblud
Note that the cost for the rent is a function of the amount of the miles you drove. Let's call that [tex]C(m)[/tex].
Also note that the amount you pay will linearly increase, in other words, the increase in cost will always be the same for each mile. This tells us that our function is indeed a line, a first order polynomial of the form [tex]C(m) = am+b[/tex]
What would happen if you were to rent a truck and not drive it at all? You would pay only the one-time fee.
Therefore, [tex]C(0)=55[/tex]
So, [tex]C(m) = am + 50[/tex]
The cost will increase by $0.20 for each mile, wich tells us that [tex]a=0.20[/tex]
Finally, our expression is [tex]\boxed{C(m) = 0.2m+55}[/tex]
If we want to know how much would you pay if you drove 65 miles, we want to know what [tex]C(65)[/tex] is.
By plugging [tex]m=65[/tex] in the expression, we get
[tex]C(65) =68[/tex]
So you would pay $68
Write a linear function f with the values f(0) = -4 and f (5) = 11.
Answer:
Let's put this function into slope-intercept form.
y = mx + b
where m is the slope
and b is the y-intercept
We know the y intercept is -3 since f(0) = -3
Thus, b = -3
To find the slope, use the equation m = (y1 - y2) / (x1 - x2)
x1 = 0
y1 = -3
x2 = 7
y2 = 11
Note: these values came from the given information
m = (-3 - 11) / (0 - 7)
= (-14) / (-7)
= 2
m = 2
Plug the values of m and b into y=mx + b
y = 2x - 3
That's your answer.
Step-by-step explanation:
A lake in East Texas was stocked with 3,000 trout in the year 2000. The number of fish in the lake is modeled by f(x) = 3000 + 100x, where x represents the number of years after 2000. Which of the following is the most reasonable domain and range for the function?
The correct answer is C
Step-by-step explanation:
I found this because the pond already has 3000 fish so y can not be less than 3000. Thus eliminating choice A since it says y>-3000.
That reasoning also eliminates answer D because real numbers can also include negatives.
Finally, since y has to be greater than 3000, answer B is not possible as it says y>0 which means it could be less than 3000.
In conclusion, Answer C is correct

Find the slope given the following ordered pairs (6,11) and (8,19)
Answer:
4
Step-by-step explanation:
solved it
Answer:
m = 4
Step-by-step explanation:
m = (y2 - y1) / (x2-x1)
Given points (6,11) and (8,19) Let y2 = 19, y1 = 11, x2 = 8, and x1 = 6
Subbing in
m = (19-11)/(8-6) = 8/2 = 4
So, the slope is 4
As of the moment I am writing this question, the population of the United States is 326,891,705 people. You are building an app that targets the US population and expect to get 1/10 of 1% of the population using your app in the first 4 months. The estimated data you need to store per user averages 10 GB. What is the minimum storage you must plan to have in place for app to serve the users in the first 4 months
Answer:
3.3 PB
Step-by-step explanation:
It is given tat the population of the U.S = 326,891,705 people.
Population expected to use the app in first 4 months = 1/10 of 1%
Storage capacity of an user is = 10 GB
Therefore,
[tex]$\frac{1}{10} \text{ of}\ 1$[/tex] % = 0.1%
= 0.001
The user content = 0.001 x 326,891,705
= 326891.705 users
10 GB storage per user.
Therefore,
Size = 326891.705 x 10
= 3268917.05 GB
= 3.26 PB
Hence size of the minimum storage would be 3.3 PB.

Meg's Bakery sells the following items.
• one cinnamon roll for $2.50 or four for $10.00
• one pie for $12.50 or two pies for $22.00
• a dozen brownies for $9.00
A. Determine if there is a proportional relationship between cinnamon rolls and the cost of cinnamon rolls. If there is determine the unit rate.
Answer:
it is $2.50 multiplied by 4
Step-by-step explanation:
this is because for every 1 cinnamon roll it is $2.50 and if you multiply that by 4 you get $10, or how much it costs for 1 roll

HEEELPPPPP PPLS The second side of a triangle is 8 inches less than the first side. The third side is 14 inches more than the first side. The perimeter of the triangle is 78 inches. Find each side of the triangle.
Answer: ):
Step-by-step explanation:
Answer:
second side is 16
third side is 38
Step-by-step explanation:
x + (x - 8) + (x + 14) = 78
3x + 6 = 78
3x = 78 - 6
3 x = 72
x = 72/3
x = 24
24 + (24 - 8) + (24 + 14) = 78
24 + 16 + 38 = 78
1. What is the value of x in the equation below? -6x + 9 = 33
Answer:
-4
Step-by-step explanation:
Step-by-step explanation:
Given
-6x + 9 = 33
or -6x = 33- 9
or, - 6x = 24
or - x = 24 / 6
or, - x = 4
Therefore x = - 4.

Answer:
1) Reflections just change the signs of the coordinates, so (1.5, -2) and (-1 and 1/2, 2) are reflections of each other. Also (1.75, -4) and (-1 and 3/4, 4)
2) From left to right: -1.75, -3/4, 1/4, 0.75, 1 and 1/2.
Remember that each 1/4 = 0.25, so this could help you work out fractions and decimals.
