Answer:

Yes, the conditions for inference are met

Step-by-step explanation:

Conditions for inference:

To build a confidence interval for a population proportion, the sample must have at least 10 successes and 10 failures.

In this question:

50 cars, 11 have damage and 50 - 11 = 39 do not.

Since both the number of sucesses and of failures is above 10, conditions for inference are met.

Solve the multi step literal equation: solve equation for A b^2A^2-3g=q
I am Lyosha [343]

Answer:

A = ± \sqrt{\frac{q+3g}{b^2} }

Step-by-step explanation:

Given

b²A² - 3g = q ( add 3g to both sides )

b²A² = q + 3g ( divide both sides by b² )

A² = \frac{q+3g}{b^2} ( take the square root of both sides )

A = ± \sqrt{\frac{q+3g}{b^2} }

When you add the same number to each side of an equation, do you always get an equivalent equation? webasign?
CaHeK987 [17]
Yes   you always do.

eg x - 2 = 8

x - 2 + 2 = 8 + 2

x = 10  
if we plug x = 10 into the original equation we se  that this fits:-

10 - 2 = 8
