Find the largest and smallest whole number when rounded to the nearest hundred to give 1600.
Answer:
Step-by-step explanation:
Smallest and largest whole number which gives 1600 when rounded to the nearest hundred.
The lowest whole number is 1550
The highest while number is 1649
Wheb rounding to the nearest hundred, the tens value which comes after the hundred value is carefully observed, of the tens value is less than 5, then it is rounded down to zero. However, if the tens value is greater than or equal to 5, it is rounded to 1 and added to the hundred value.
Numbers below 1550 will not round to 1600 (nearest 100) also numbers greater than 1649will not round to 1600(nearest 100).butvall numbers in between them will round to 1600 (nearest hundred)

What are the solutions to –2x+ 2 = (3) +1?
Answer:
x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+2=3+1
Step 1: Simplify both sides of the equation.
2x+2=3+1
2x+2=(3+1)(Combine Like Terms)
2x+2=4
2x+2=4
Step 2: Subtract 2 from both sides.
2x+2−2=4−2
2x=2
Step 3: Divide both sides by 2.
2x2=22

Melinda conducted an experiment regarding the effectiveness of two graphic design training courses, Image-nation and Perfect Pics. She randomly selected 20 people from her marketing team and assigned 10 team members to each training course.
To determine the effectiveness of Image-nation and Perfect Pics, Melinda assigned the same task to all participants at the beginning and at the end of each program. She stated that a training course is effective if there is a decrease in time required to complete a graphics task. At the beginning of each course, Melinda found the average time to complete a task for Image-nation participants to be 60 minutes and the average time to complete a task for Perfect Pics participants to be 70 minutes. At the end of each training course, Melinda found the time taken to complete a task for Image-nation participants to be 50 minutes and the average time to complete a task for Perfect Pic participants to be 55 minutes.
Which statement should be included in Melinda’s report of the experiment's results?
A.
The Image-nation and Perfect Pics courses are both effective because the average time to complete a task decreased for each program; however, Image-nation is the more effective program because it yielded a greater decrease in the average time to complete a task.
B.
Perfect Pics is the only course that resulted in a decreased average time to complete a task; therefore, Perfect Pics is the more effective course.
C.
Image-nation is the only course that resulted in a decreased average time to complete a task; therefore, Image-nation is the more effective course.
D.
The Image-nation course and the Perfect Pics course are both effective because the average time to complete a task decreased for each course; however, Perfect Pics is the more effective course because it yielded a greater decrease in the average time to complete a task
Answer: c
Step-by-step explanation:....
The statement 'The Image-nation course and the Perfect Pics course are both effective because the average time to complete a task decreased for each course; however, Perfect Pics is the more effective course because it yielded a greater decrease in the average time to complete a task' should be included in Melinda’s report of the experiment's results.
The correct answer is option (D)
What is average?"It is calculated by adding all the numbers and then dividing by total count of those numbers."
For given example,
At the beginning of each course,
the average time to complete a task for Image-nation participants to be 60 minutes
⇒ t1 = 60
the average time to complete a task for Perfect Pics participants to be 70 minutes
⇒ x1 = 70
At the end of each training course,
the average time taken to complete a task for Image-nation participants to be 50 minutes
⇒ t2 = 50 minutes
the average time to complete a task for Perfect Pic participants to be 55 minutes.
⇒ x2 = 55 minutes
The decrease in average time to complete a task for Image-nation is,
t1 - t2
= 60 - 50
= 10
And the decrease in average time to complete a task for Perfect Pics is
x1 - x2
= 70 - 55
= 15
This means, Perfect Pics is the more effective course because it yielded a greater decrease in the average time to complete a task.
Therefore, the statement 'The Image-nation course and the Perfect Pics course are both effective because the average time to complete a task decreased for each course; however, Perfect Pics is the more effective course because it yielded a greater decrease in the average time to complete a task' should be included in Melinda’s report of the experiment's results.

Find the median of the following numbers: 195, 230, 200, 226
Answer: 213
Step-by-step explanation: The median is the middle number
in the data set when the data set is written from least to greatest.
So let's start with writing ur data set from least to greatest.
So we have 195, 200, 226, 230.
Notice that there are two middle numbers.
If there are two middle numbers in the data set,
we find the median by taking their average.
In other words, we add the two middle numbers and divide by two.
So we have 200 + 226/2 or 426/2 which is 213.

Step-by-step explanation:
A merchant gains 20 %by selling an article for rs 480. what percent would he have gained or lost if he had sold it for rs 430
Answer: 7.5% gain
Step-by-step explanation:
First find the original price of the article.
Assume this price to be x.
x + (x * 20%) = 480
x + 0.2x = 480
1.2x = 480
x = 480/1.2
x = Rs. 400
Original price is Rs. 400.
If the merchant had sold the article for 430, the percent gain would have been:
= (Selling price - original price) / Original price
= (430 - 400) / 400
= 7.5%

how would the expression x^3-8 be rewritten using difference of cubes?
A- (x+2)(x^2+2x-4)
B- (x-2)(x^2-2x+4)
C-(x+2)(x^2-2x+4)
D-(x-2)(x^2+2x+4)
Answer:
D
Step-by-step explanation:
Difference of cubes is as follows
x^3-y^3=(x-y)(x^2+y^2+xy)
*notice how the sign in the origonal equation is the same for the first part but then flipped for the second*****
8 can be rewritten as 2^3 so we have
x^3-2^3 which means that we can use the template from before
(x-2)(x^2+2^2+2x)
simplify the 2^2 into 4 and put the variables in front to get
(x-2)(x^2+2x+4)
This is the same as D

.
Robero will randomly choose 1 book to read. What is the probability that he will
choose an adventure book?
Answer:
Step-by-step explanation:
How many books are there?
6+5+4+3 = 18 books total
How many are adventure books?
3
3 out of 18 books are adventure books
Robero has a 3/18 probability of choosing an adventure book.
Your teacher might want that probability in the lowest possible form. That is because it is the easiest to use and to understand.
You can do this by dividing both numbers by the "numerator" which is the first number in the fraction, (the adventure book count).
3/3 = 1
18/3 = 6
So the fraction can be reduced to 1/6.
Robero has a 1/6 chance of choosing an adventure book.
