What is the median for the set of data?
71
70
72
74
Answers
Answer:
Step-by-step explanation:
To find the median, we need to arrange the data in ascending order:
70, 71, 72, 74
Since the data set has an even number of values, the median is the average of the two middle values. In this case, the two middle values are 71 and 72. Therefore, the median is:
(71 + 72) / 2 = 143 / 2 = 71.5
So, the median for the given set of data is 71.5.

The length of a rectangular picture frame is 4 inches shorter than its width. If the perimeter of the picture frame is 44 inches, what is the length, l, and width, w, of the frame? Write and solve an equation to model the problem.
Answers
Answer:
11
Step-by-step explanation:
44*4=44
The length of the picture frame is 6 inches and the width is 10 inches.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
Let's represent the width of the picture frame "w" and the length of the picture frame "l". We know that the width is 4 inches longer than the length, so we can write the equation:
w = l + 4
The perimeter of the picture frame is the sum of all four sides, so we can write the equation:
2w + 2l = 44
We can substitute the first equation into the second equation to get:
2(l + 4) + 2l = 44
This simplifies to:
4l + 8 + 2l = 44
Combining like terms, we get:
6l + 8 = 44
Subtracting 8 from both sides, we get:
6l = 36
Dividing both sides by 6, we get:
l = 6
Substituting this value back into the equation w = l + 4, we get:
w = 6 + 4
Simplifying, we get:
w = 10
Thus, the picture frame is 6 inches in length and 10 inches in width.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500

Answers
Answer:
[ 2] − | −5 + 7 |
Step-by-step explanation:
Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.
Step 1) Solve. | −5 + 7 | = 2.
Step 2) Find which other absolute value is equal to -2.
After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.
We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0
We start by simplifying | −5 + 7 |:
| −5 + 7 | = | 2 | = 2
Now we can simplify each of the answer choices:
[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2
We see that only choice [2], when added to | −5 + 7 |, will equal zero:
2 + (−2) = 0
Therefore, the answer is [2] | +5 − 7 |.

What is the combination?Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.
The number of r-element combinations of n objects, with repetition is:
\(\overline{C}_{n,k} = \: ^{n + k-1}C_{k} = \dfrac{(n+k-1)!}{k! \times (n-1)!}\)
