Answer:
-2.5
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
=
-5
2
= -2.5
θ =
arctan( ΔY ) + 360°
ΔX
= 291.80140948635°
ΔX = 7 – 5 = 2
ΔY = -2 – 3 = -5
Distance (d) = √ΔX2 + ΔY2 = √29 = 5.3851648071345
Equation of the line:
y = -2.5x + 15.5
or
y =
- 5 x
2
+ 31
2
When x=0, y = 15.5
When y=0, x = 6.2
To identify which data set is represnted by the box plot, find the data set that has the exact five-nunber summary of the box plot given.
<h3>What is a Box Plot?</h3>
If you identify the five-number summary of a data set, you can easily draw a box plot, because the values of each of the five-number summary is exactly what you are going to see on a box plot.
The min, max, lower and upper quartile, and median, which are the five-numnber summary of a data set is displayed as shown in the box plot attached below.
Therefore, to identify which data set is represnted by the box plot, find the data set that has the exact five-nunber summary of the box plot given.

Is there any sums that you needed to solve this with?
Answer:
The number of people needed is
Step-by-step explanation:
From the question we are told that
The population proportion is 
The margin of error is 
From the question we are told the confidence level is 90% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the sample size is mathematically represented as
![n =[ \frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * p(1-p)](https://tex.z-dn.net/?f=n%20%3D%5B%20%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20p%281-p%29)
=> ![n =[ \frac{1.645 }{0.03} ]^2 * 0.65(1-0.65)](https://tex.z-dn.net/?f=n%20%3D%5B%20%5Cfrac%7B1.645%20%7D%7B0.03%7D%20%5D%5E2%20%2A%200.65%281-0.65%29)
=>
If you solve the inequality the result is
4x - 3 <u>></u> 5<u>
</u> +3 +3
_________
4x <u>></u> 8 Now divide both sides by 4
x <u>></u> 2 Is the result of solving the inequality
Your solution set is all real numbers 2 and greater
Therefore, C {2,3,4) is your solution set
