Answer:
B. 288 In
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
x*(x-2)-(288)=0
x • (x - 2) - 288 = 0
Find two factors of -288 whose sum equals the coefficient of the middle term, which is -2 .
-288 + 1 = -287
-144 + 2 = -142
-96 + 3 = -93
-72 + 4 = -68
-48 + 6 = -42
-36 + 8 = -28
-32 + 9 = -23
-24 + 12 = -12
-18 + 16 = -2 That's it
Answer: 288

Step-by-step explanation:
We know she made 21/22. That means she miss 1 so subtract 21 from 22. We get 1. then divide 22 by 1. So the equation is
[tex] \frac{1}{22} [/tex]
which is about 0.454. Then multiply by 100 to get the percent which is 4.54. Round to nearest tenth and we get 4.5%

Austin wrote 3 1 3 as the sum of fractions. What fractions might Austin have used?
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Sum = 3\frac{1}{3}[/tex]
Required
Determine the fraction used
Since options, were not given. I'll answer on a general term
Assume, Austin used 2 fractions (a and b)
Such that:
[tex]a + b = 3\frac{1}{3}[/tex]
Also:
Assume that:
[tex]a = \frac{2}{3}[/tex]
Note that this could be any fraction, but I chose to use 2/
Make b the subject in [tex]a + b = 3\frac{1}{3}[/tex]
[tex]b = 3\frac{1}{3} - a[/tex]
[tex]b = 3\frac{1}{3} - \frac{2}{3}[/tex]
[tex]b = \frac{10}{3} - \frac{2}{3}[/tex]
Take LCM
[tex]b = \frac{10-2}{3}[/tex]
[tex]b = \frac{8}{3}[/tex]
[tex]b = 2\frac{2}{3}[/tex]
So, the fractions are:
[tex]a = \frac{2}{3}[/tex] and [tex]b = 2\frac{2}{3}[/tex]

Answers
Answer:
a = 22
Step-by-step explanation:
To find a, divide each side by 1/2, or multiply by the reciprocal:
1/2a = 11
a = 22
So, a = 22
Answer:
a = 22
because when isolate a you move 1/2 over with 11, and when you do that insted of multyplying 1/2 times a you divide 1/2 by 11

Answers
Answer:Median = Mid value of Set of observation
If number of observation is odd, suppose n
Median = th term
If number of observation is even , then
Median = Mean of two middle observation i.e
Data set : 17, 20, 30, 28, 18
Data arranged in ascending order: 17,18,20,28,30
Let one data =x
Number of observation is even.
Given, Median = 24
As , when number of observation is even , median is mean of two mid values.
Median=→→→ getting the median.
So, x must be greater than 30.
The correct option satisfying the above condition is Option (D) 34.
Step-by-step explanation:
Answer:
A. The missing number is 11
Step-by-step explanation:
The highest number in the set is 30 and the lowest is 12, this makes the range 18.
30 is supposted to be there to make the range what the problem says it is: 12.
20 and 25 could be there because no matter what, as long as 30 is the greatest number, 20 and 25 don't effect the range AT ALL.
If 11 was in the number sequence, the lowest number would be 11, making the range 19, (30-11=19) which is not what the teacher is saying the range is.
So in short, A. The missing number is 11 is the correct answer.

Guys I need help. How do I solve 3/4 + 5/8 + 2/3 - 1/6 ?
Answers
Answer:
15/8
Step-by-step explanation:
Literally find the common denomiator. That's the first step for any of these computational fraction problems.
Here are the following denomiators: 4,8,3,6. You notice that 24 is a multiple of all the numbers. Thus, our common denomiator is 24. Next we change each fraction based on our new denomiator
3/4 = 18/24
5/8 = 15/24
2/3 = 16/24
1/6 = 4/24
Now we do basic computation
18/24 + 15/24 + 16/24 - 4/24 = 45/24 = 15/8

Step-by-step explanation:
Use the converse of the Pythagorean theorem. Square the lengths and see if 2 results add up to the third result.
So, Set 1
[tex]10^{2} = 100 \\26^{2} = 676\\24^{2} = 576[/tex] 100 + 576 = 676 Therefore we have a right triangle
Set 2
[tex]4^{2} = 16\\2^{2} = 4\\6^{2} = 36[/tex]
16 + 4 ≠ 36 Therefore we do NOT have a right triangle
I will let you do Set 3 and Set 4. OK?

Question 17 The probability that a customer's order is not shipped on time is 0.02. A particular customer places three orders, and the orders are placed far enough apart in time that they can be considered to be independent events. Round your answers to four decimal places (e.g. 98.7654). (a) What is the probability that all are shipped on time
Answers
Answer:
0.941192 = 94.1192% probability that all are shipped on time
Step-by-step explanation:
For each order, there are only two possible outcomes. Either they are shipped on time, or they are not. The probability of an order being shipped on time is independent of other orders. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The probability that a customer's order is not shipped on time is 0.02.
So 1 - 0.02 = 0.98 probability of being shipped on time, which means that [tex]p = 0.02[/tex]
A particular customer places three orders
This means that [tex]n = 3[/tex]
(a) What is the probability that all are shipped on time
This is [tex]P(X = 3)[/tex].
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{3,3}.(0.98)^{3}.(0.02)^{0} = 0.941192[/tex]
0.941192 = 94.1192% probability that all are shipped on time
