4x + 3 = 4x + 15 solve for x Plese help

ira [324]

4x - 15 = 3 
4x = 3 + 15 
4x = 18 (divide both sides by 4 to get x) 
4x/4 = 18/4 
x = 4.5

Angle A and angle B are complementary

Nikitich [7]

Answer:

Step-by-step explanation:

∠A + ∠B = 90° {given they are complementary}

5x+ 15 + 30 = 90

5x + 45 = 90

5x = 90 - 45

5x = 45

x = 45/5

x = 9

Given the data shown below, which of the following is the best approximation of the coefficient of determination (r^2)

HACTEHA [7]

The coefficient of determination can be found using the following formula:

$r^2=\mleft(\frac{n(\sum ^{}_{}xy)-(\sum ^{}_{}x)(\sum ^{}_{}y)}{\sqrt[]{(n\sum ^{}_{}x^2-(\sum ^{}_{}x)^2)(n\sum ^{}_{}y^2-(\sum ^{}_{}y)^2}^{}}\mright)^2$

Using a Statistics calculator or an online tool to work with the data we were given, we get

So the best aproximation of r² is 0.861
