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
$4500
$4500
For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

The box plots show the weights, in pounds, of the dogs in two different animal shelters.
Weights of Dogs in Shelter A
2 box plots. The number line goes from 6 to 30. For the weights of dogs in shelter A, the whiskers range from 8 to 30, and the box ranges from 17 to 28. A line divides the box at 21. For shelter B, the whiskers range from 10 to 28, and the box ranges from 16 to 20. A line divides the box at 18.
Weights of Dogs in Shelter B
Which describes the spread of the data in the two box plots?
The data in shelter A show more spread than the data in shelter B.
The data in shelter B show more spread than the data in shelter A.
The data in shelter A range from about 17 to 28, while the data in shelter B range from about 16 to 20.

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart shows the effect of adding or taking away a pamphlet. Pamphlets Added to the box(x) Effect on the Box's Weight (y) 0 0 1 6 2 12 3 18 Is this an example of continuous or discrete data? discrete continuous
Answers
Answer:
This example represents discrete data.
Step-by-step explanation:
Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.
In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.
Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

The Answer to the first question is 27 cubic millimeters.
Step-by-step explanation:
The original formula for volume is V= l×w×h
When you find the volume of a cube, use this formula; V=s^3.
V is for Volume.
s is for the measurement of the side.
3 is for the length, width, and height.
First, just plug the number in; V=3^3. Or 3×3×3.
Second, Multiply; V=27

how can you convert among fractions, decimals, and percents
Answers
Answer:
Step-by-step explanation:
Changing Percents to Decimals
The word percent means "per 100." 20% means 20 out of 100, or 20/100. 67% means 67 out of 100, or 67/100. So to change a percent to a decimal, you simply divide the percentage number by 100. When you divide by 100, the decimal just moves over 2 places to the left.
Changing Percents to Fractions
Remember, the word percent means "per 100." This means you can change a percent to a fraction by dividing by 100. Don't stop here though, make sure to simplify the fraction if possible. Look to see if the numerator and denominator can be divided by the same number.
Changing Decimals to Fractions
First, figure out the place value of the last digit on the right. Is it in the tenths place? Hundredths? Thousandths? Use the place value to write the decimal as a fraction over 10, 100, 1000, etc. Then simplify the fraction if possible.
Remember, the first place to the right of the decimal is the tenths place. The second place is the hundredths, then thousandths, ten thousandths, and so on.
A fraction to a percent multiply the fraction by 100 and reduce it
A decimal to fraction
A decimal to percent
A percent to a decimal
A percent to a fraction

If a value of 103° is added to the data, how does the mean change?
The mean increases by 1.7°.
The mean decreases by 1.7°.
The mean increases by 8.6°.
The mean decreases by 8.6°.
Answers
Answer:
The mean increases by 1.7°
Step-by-step explanation:
1) Find the mean of the numbers given first
Mean = sum of number ÷ number of numbers
Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 = 965
Number of numbers = 12
965 ÷ 12 = 80.41666....2) Find the mean of numbers including the additional 103
Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 103 = 1068
Number of numbers = 13
1068 ÷ 13 = 82.15384623) Find the difference
If we use the results rounded to one decimal place we will be left with 80.4 and 82.2
82.1538462 - 80.41666... = 1.7The answer closest to the options given would be 'The mean increases by 1.7'Hope this helps, have a lovely day :)
