Answers
Answer:
See belowStep-by-step explanation:
The relation is not a function when x -value is same but y- values are different.
#1
k^2 = 4kk = 0, k = 4#2
k^2 - 5k = k + 7k^2 - 6k = 7k^2 - 6k + 9 = 16k - 3 = 4 ⇒ k = 7k - 3 = -4 ⇒ k = -1#3
k^3 - 5k^2 + 3k = -kk^3 - 5k^2 + 4k = 0k(k^2 - 5k + 4) = 0k = 0, k = 1, k = 4#4

Based on a random sample of 200 graduates of the business school, a 98 percent confidence interval for the slope of the linear regression line relating placement scores and starting salary is calculated to be (315,336). Assume the conditions for inference are met.
Which of the following is a correct interpretation of the confidence interval?
a. There is a 98 percent probability that the slope of the population regression line is between $315 per point and $336 per point.
b. Ninety-eight percent of the time, a 10-point increase in placement score will result in an average increase between $3,150 and $3,360 in starting salary.
c. We are 98 percent confident that a 10-point increase in placement score will result in a predicted increase in starting salary of between $3,150 and $3,360.
d. We are 98 percent confident that predicted starting salaries will be between $315,000 and $336,000.
e. We are 98 percent confident that the regression equation can be used to make accurate predictions for placement scores between 315 and 336.

Evaluate: x + (x2 - xy) - y
if x = 5 and y = 4
Answers
When x = 5 and y = 4, the expression [tex]x + (x^2 - xy) - y[/tex] evaluates to 6.
To evaluate the expression [tex]x + (x^2 - xy) - y[/tex] when x = 5 and y = 4, we substitute the given values into the expression and perform the
calculations:
[tex]x + (x^2 - xy) - y\\x= 5 + (5^2 - 5*4) - 4\\x= 5 + (25 - 20) - 4\\x= 5 + 5 - 4\\x= 10 - 4\\x= 6\\[/tex]
It's crucial to remember that the expression in question is not an equation that represents a graph, nevertheless. It is merely an algebraic expression that, given the values of "x" and "y," evaluates to a single value. We need an equation that connects 'x' and 'y' and specifies the relationship between them if we are to construct a graph.
Therefore, when x = 5 and y = 4, the expression [tex]x + (x^2 - xy) - y[/tex] evaluates to 6.

Gina buys a car for $13,500. The value is expected to depreciate by 15% per year.
Write an exponential function to model the value of the car. When will the value
fall below $3000?
Answers
Answer:
the value will fall below $3000 in the 7 th year because :
Step-by-step explanation:
15% of 13500 is 2025
On subtracting 2025 from 13500 every time we can see that the value keeps dropping.
So, we will get $3375 in year 6 and in year 7 we will get $1350 by subtracting 2025 from 3375.
Hence we will get 1350 at the 7th year.
After 6.79 years, the car's value will drop below $3,000.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Now, The following is a representation of the exponential function to model the car's value:
V(t) = 13500 (1 - 0.15)ⁿ
V(t) = 13500(0.85)ⁿ
Here, V(t) denotes the car's worth at time n in years, and 0.85 denotes the annual depreciation rate of 15%.
Hence, The following equation can be put up to determine when the car's value will drop below $3,000:
13500(0.85)ⁿ = 3000
As we solve for n, we obtain:
n = (log(3000/13500)/log(0.85))
n = 6.79
So, after roughly 6.79 years, the car's value will drop below $3,000.

Describe the shape of the data summarized in the histograms.
Answers
Answers:
5) Roughly symmetrical6) Skewed to the right (aka "right skewed" or "positively skewed")=======================================================
Explanation:
5) We don't have perfectly symmetrical data, as that would require the left half to be a perfect mirror copy of the right half. However, we have some semblance of symmetry going on. In the middle is 5 which is where the highest bar is, where the mode is located. The mean and median are likely to be around here as well. Then on either side of this highest peak are bars of shorter heights. The heights decrease as we move away from the center in either direction. We can draw an estimated or approximated bell curve (aka normal distribution curve or gaussian curve) to get a fairly good sense of how the data is roughly symmetric. The right-hand portion of this graph is shorter compared to the left side, but I don't think that's enough info to say if we have skewed data or not; so I would stick with "roughly symmetric" here.6) Unlike problem 5, we don't have symmetric data. Instead, we have data that is skewed to the right. The main cluster is grouped or centered on the left side, while we have some outliers to the right side. Draw a curve over each peak of the bars and you'll see that the right tail is pulled longer than the left tail is. We consider this a positively skewed distribution because there are outliers in the positive x direction compared to the main cluster. In contrast, a negatively skewed distribution would have outliers smaller than the main cluster. The mean is larger than the median for a right-skewed distribution. This is due to the mean being pulled on by the outlier, while the median is robust and isn't affected by outliers no matter how distant they are.Write 24:14:6 in its simplest form.

Answer:
12 : 7 : 3
Step-by-step explanation:
24 : 14 : 6
12 : 7 : 3
Always start with smaller number to simplify it. Since 2 is the smaller number and it simplifies 24, 14, and 6 I start with it.
24 ÷ 2 = 12
14 ÷ 2 = 7
6 ÷ 2 = 3
We would stop here since it would not further simplify, therefore our answer is 12 : 7 : 3.

Step-by-step explanation:
Segment ZX can divide the figure into two right triangles. Then angle XZY is 136°/2 = 68°. The tangent relation tells you ...
Tan = Opposite/Adjacent
tan(68°) = XY/r
r = 12/tan(68°) ≈ 4.848 ≈ 4.8
The radius of the circle is about 4.8 units.
