Answers
For a curve to be a density curve, it must meet certain conditions such as it should be non-negative, and the area under the curve should equal 1. Furthermore, the curve should be continuous and smooth, and there should be no values outside the range of the data.
Let's see how the height would need to be for this curve to be a density curve.A density curve is a statistical representation of the distribution of a dataset or population. Density curves are used to describe the distribution of continuous data and provide a visual representation of the likelihood of an event occurring within a specific range of values. It helps to determine the proportion of data that falls within a given range of values. A density curve is used to provide a graphical representation of data without showing the individual data points.To be a density curve, a curve must have the following properties:The curve should be non-negative.The area under the curve should be equal to 1.The curve should be smooth and continuous.There should be no values outside the range of the data.From the above properties, we can conclude that the height required for a curve to be a density curve depends on the data that the curve represents. As long as the curve meets the above conditions, it can be considered a density curve. So, there is no specific height required for a curve to be a density curve. The height of the curve can vary depending on the range of the data and the distribution of the data.For such more question on properties

Given y=1/4x+2 I first isolate the constant. After doing so, I get the equation -1/4x+y=2 To remove the fraction, I multiply by –4, giving the equation x-4y=2 which is the final answer. A. the work shown to isolate the constant is not correct B. the work shown to remove all fractions is not correct C. the final answer is not in standard form D. the work shown is correct
Answers
The statement that applies to the sample math is:
B. the work shown to remove all fractions is not correct
How to change the subject of the formula?The given steps are:
y = ¹/₄x + 2
- I first isolate the constant.
- After doing so, I get the equation: -¹/₄x + y = 2
- To remove the fraction, I multiply by –4, giving the equation x - 4y=2, which is the final answer.
The correct steps are as follows:
y = ¹/₄x + 2
First isolate the constant to get: y - ¹/₄x = 2
To remove the fraction, Multiply the obtained equation by –4
So, Equation : x - 4y = -8
On comparing both the work we can see that in the given work the removal of fraction is done incorrectly
They didn't multiply -4 on the right hand side .
Thus, option B applies.

Carla has 5 times as many notebooks as her brother does they have 42 notebooks between them, how many note- books does Carla have?
Answers
Let the number her brother has = x
She has 5 times as many so she has 5x
Together they have 42:
X + 5x = 42
Add x and 5x to get 6x:
6x =42
Divide both sides by 6:
X = 7
The brother has 7
Carla has 5*7 = 35
Answer: Carla has 35 notebooks
6. Emily receives an inheritance of $20,000 and decides to invest the money. She puts some money in her savings
account that earns 1.5% simple interest per year. The remaining money is invested in a bond fund that returns 4.5% and a
stock fund that returns 6.2%. She makes a total of $942 at the end of 1 yr. If she invested twice as much in the bond fund
as the stock fund, determine the amount that she invested in each fund.
Answers
Emily funded $6000 in stocks and $12,000 in bond funds. She also funded the remaining $2,000 in her savings account.
Future value = $20,000
Simple interests rate = 1.5%
The return rate on bonds= 4.5%
The return rate on stocks = 6.2%
Total amount made on invests = $942
Time period = 1 year
Let us assume that the amount of money Emily invested = x
Amount invested in stock = y
If the amount is twice = 2y
The interest earned = x * 0.015
Interest on bond = 2y * 0.045
Interest on stocks = y * 0.062
The equation will be:
(x * 0.015) + (2y * 0.045) + (y * 0.062) = 942
0.015x + 0.152y = 942 ------ Equation 1
Total future value is given as $20,000
x + 2y + y = 20000
x + 3y = 20000
x = 20000 - 3y
Substituting the x value in the first equation:
0.015(20000 - 3y) + 0.152y = 942
300 - 0.045y + 0.152y = 942
0.107y = 642
y = 6000
Therefore, we can conclude that Emily funded $6000 in stocks and $12,000 in bond funds.

a movie is 17/8 hours long after 45 minutes how much time is left
Answers
Answer:
82.5 minutes
Step-by-step explanation:
We have to figure out how many minutes are in 17/8 hours. 17/8 = 2 1/8 hours. We know that 2 hours is 120 minutes.
1/8hours x 60 min = 7.5 minutes.
120 + 7.5 = 127.5 minutes then subtract out 45. That leaves 82.5 minutes.

use the display of data items to find the mean, median, mode, and midrange. Any help and explanation on how to this with the stem/leaf plot is appreciated! Thanks in advance!
Answers
Considering the given stem-and-leaf plot, the statistical measures are given as follows:
Mean: 72.7.Median: 78.Mode: 78.Mid-range: 22.5.What is shown by a stem-and-leaf plot?The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:
5|5 = 55.
Hence, in this problem, the measures are given as follows:
51, 55, 57, 70, 78, 78, 79, 90, 96.
The mean is the sum of all the measures divided by the number of measures, hence:
Mean = (51 + 55 + 57 + 70 + 78 + 78 + 79 + 90 + 96)/9 = 72.7.
The median is the middle value of the data-set. The data-set in this problem has nine observations, hence the middle value is the 5th observation, which is of 78.
The mode is the observation that appears the most times, which is also 78, as it is the only measure appearing twice.
The mid-range is half the difference of the highest value in the data-set by the lowest value, hence:
Mid-range = 0.5 x (96 - 51) = 22.5.

To determine the 'intervals of increase' and 'intervals of decrease' we can refer to the graph with respect to the x - axis.
• Knowing that t = x - axis, the 'intervals of increase' as an inequality would be 1 < x < 3, and 4 < x < ∞. Therefore we have our intervals of increase as (1,3) and (4, ∞).
• Respectively our 'intervals of decrease' as inequalities would be - ∞ < x < 1, and 3 < x < 4. Our intervals of decrease would then be (- ∞, 1) and (3,4).
• We are left with our local extrema and absolute extrema. Now remember the absolute extrema is the absolute lowest point in the whole graph, while the local extrema is the lowest point in a restricted interval. In this case our local extrema is our maximum, (3,1). But this maximum is not greater than the starting point (0, 4) so it appears, and hence their is no absolute extrema.

Question: Determine whether the scenario is independent or dependent. Calculate the probability. Mr. Tindel will randomly Selects two students from his class as the student council representatives There are 17 girls and 6 boys in his class. what is the probability Mr. Tindel will select two girls?
Answers
The probability of selecting two girs from the group is given by:
\(P(girl1)\times P(girl2)\)The probability of selecting a girl first, is given by the division between the amount of girls in the class by the total number of people in the class.
• Number of girls in the class: ,17
,• Total number of people: 17 girls+6boys=,23 ,people
Probability of selecting first a girl:
\(P(girl1)=\frac{17}{23}\)--------------------------------------
Now we calculate the probability that, after selecting a girl, we select another girl in the second place. Again we need the total number of girls:
• Number of girls available for selecting: ,16
We substract 1 girl from the total because we already select one girl in the first place.
For this same reason, the total number of people in the class will also decrease by 1:
• Total number of people: ,22
And thus, the probability of selecting a girl in the second place is:
\(\frac{16}{22}=\frac{8}{11}\)Finally, as stated at the beginning, we multiply both probabilities to find the probability Mr. Tindel will select two girls:
\(P(girl1)\times P(girl2)=\frac{17}{23}\times\frac{8}{11}=\frac{17\times8}{23\times11}=\frac{136}{253}\)which in percentage is:
\(\frac{136}{253}=0.537\)53.7%
Determine whether the scenario is independent or dependent:
The scenario is dependent, because the second probability depends on the result of the first event.
