Answer:
A. 4.8 units
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.
Answer: 4.8 units

Your parents car initially costs $18,000 and it depreciates at a rate of 12% a year. How much will the car be worth after 5 years.
Using this equation, when your parents give you the car when the value drops below $2,000, in what year of depreciation will you become the owner?
Answer:
Step-by-step explanation:
value after five years = $18,000×(1-0.12)⁵ = 18,000×0.88⁵ = $9,499.17
:::::
The value drops below $2,000 in the 17th year.

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?
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.

A population has a standard deviation of 11. What is the approximate standard error of the mean for a sample size of 150?
Answer:
the approximate standard error is 0.90
Step-by-step explanation:
The computation of the approximate standard error is shown below:
As we know that
Standard error is
= Standard deviation ÷ √mean
= 11 ÷ √150
= 11 ÷ 12.247
= 0.90
Hence, the approximate standard error is 0.90

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.
Hope this helps, thank you :) !!
Describe the shape of the data summarized in the histograms.
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.A solution of a battery is 14% sulfuric acid.
