Answer:

4x+9=x+15

x = 2

Step-by-step explanation:

Let's solve this equation I just made:

4x + 9 = x + 15

Subtract 9 from each side:

4x = x + 6

Subtract x from each side:

3x = 6

Divide each side by 3:

x = 2

Determine whether the following sampling is dependent or independent. Indicate whether the response variable is qualitative or q

NeTakaya

Answer:

1. option D

2. option A

Step-by-step explanation:

Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Thus, this sampling is independent. The sampling is independent because an individual selected for one sample does not dictate/affect which individual is to be in the second sample.

The variable is qualitative because it is an attribute classification. A qualitative variable are variables that are not numerical. It describes data that fits into categories (personality type).

Find the perimeter of the triangle defined by the coordinates (9, 0), (-5, 0), and (-10, 6). (Round to nearest tenth)

Masteriza [31]

The perimeter is 41.7

Find the length of each side using the distance formula:
$d=\sqrt{(0-0)^2+(-5-9)^2}=\sqrt{0^2+14^2}=\sqrt{196}=14
\\
\\d=\sqrt{(6-0)^2+(-10--5)^2}=\sqrt{6^2+(-5)^2}=\sqrt{36+25}=\sqrt{61}=7.8
\\
\\d=\sqrt{(6-0)^2+(-10-9)^2}=\sqrt{6^2+(-19)^2}=\sqrt{36+361}=\sqrt{397}=
\\19.9$

Adding the side lengths, we have
14+7.8+19.9=41.7

Radius = 9m
Diameter = 18 m
Area = 254.34 squared m
Circumference = 56.52 m

I’m guessing is asking for the circumference because it says around
