Answer:
3.2 units
Step-by-step explanation:
Since the perimeters of the rectangles are equal:
n + n + 0.6 = n +0.1 + 2n
2n + 0.6 = 3n + 0.1
0.5 = n
Left Rectangle:
2 (0.5 + 0.5 + 0.6) = 3.2 units
Since they have the same perimeter, the rectangle on the right also has a perimeter of 3.2 units.
The value of alpha is 0.26, assuming a confidence level of 74%.
<h3>What is the margin of error?</h3>
The significance level α is the probability of making the wrong decision when the null hypothesis is true.
Alpha levels which is also called as significance levels are used in hypothesis tests.
Given
When finding the margin of error for the mean of a normally distributed population from a sample.
The confidence interval = 74% = 0.74.
The value of the alpha is given by;
Substitute all the values in the formula
Hence, the value of alpha is 0.26, assuming a confidence level of 74%.

Answer:
Volume = 2512 km³
Volume = 800π km³
Step-by-step explanation:
Volume Cylinder = Area circle * height
Let's input the info
Formula for the Area of a circle = πr²
Area circle = π*100
Since it asks to leave in terms of π or tenths ill give both.
Area circle = 100π
Area circle = 314
Volume = 100π * 8
Volume = 800π
Volume = 314 * 8
Volume = 2512
Units = km³
Volume = 800π km³
Volume = 2512 km³

Step-by-step explanation:
(x₁ , y₁) = (-1 , -2) & (x₂ , y₂) = (3 , 10)
![= \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B10-%5B-2%5D%7D%7B3-%5B-1%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B10%2B2%7D%7B3%2B1%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B4%7D%5C%5C%5C%5C%3D4)
m = 4
y - y₁ = m (x - x₁)
y - [-2] = 4(x - [-1])
y + 2 = 4(x + 1)
y + 2 = 4x + 4
y = 4x + 4 - 2
y = 4x + 2
Median is the middle number and you have to put each set in order like you've done, tick each number off and each side working in:
3,4,-6-,7,8 =6
3,3,-4-,5,5 =4
6,7,-7-,8,9 =7
2,2,-3-,4,6 =3
Mode is the number that shows up the most
3,4,6,7,8= no mode
3,3,4,5,5= 3 and 5
6,7,7,8,9=7
2,2,3,4,6=2
6,7,7,8,9 both have 7 for mode and median
