6 0

30 + 2w = 2 • (w - 15)

Equation at the end of step 1 :
Step 2 :
Equations which are never true :
Solve : 2 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation
Solve : w-15 = 0

Add 15 to both sides of the equation :
w = 15

You are trying to solve for "w", to do so you:

20 + 2w = 50 Subtract 20 on both sides

2w = 30 Divide 2 on both sides to get "w" by itself

w = 15

Your answer is B

Answer:

C.It is a one-tailed test since the alternative hypothesis states that the parameter is greater than the hypothesized value.

Step-by-step explanation:

Let p be the percentage of students enrolled in an introductory Chemistry class dropped before the midterm. Then null and alternative hypotheses are:

$H_{0}$ : p=10%

$H_{a}$ : p>10%

The alternative hypothesis states that the parameter is greater than the hypothesized value.

Function: y = 2x²-5

<u>Find y-intercept:</u>

y = 2(0)²-5

y = -5

<u>Find x-intercept:</u>

2x²-5 = 0

2x² = 5

x² = 2.5

x = ±√2.5

x = -1.5811 , 1.5811
