-2( -4x - 2 ) - 5x + 5 = -12

After solving the given equation, you will find out that x= -7

Step-by-step explanation:

From my understanding, the unknown value of x has to be calculated in this equation

<em>1. Bracket open</em>

-2(-4x - 2) - 5x + 5 = -12

8x + 4 -5x + 5 = -12

<em>2. Take all variables at the left side and all numbers at the right side</em>

8x - 5x = -12-4-5

<em>3. Make x the subject</em>

3x = -21

x = \frac{-21}{3}

<em>4. Solve to find x</em>

x = -7

Therefore, the value of x is -7

In 2011, a U.S. Census report determined that 71% of college students work. A researcher thinks this percentage has changed sinc
coldgirl [10]

Answer:

Note: The full question is attached as picture below

a) Hо : p = 0.71

Ha : p ≠ 0.71

<em>p </em>= x / n

<em>p </em>= 91/110

<em>p </em>= 0.83.

1 - Pо = 1 - 0.71 = 0.29.

b) Test statistic = z

= <em>p </em>- Pо / [√Pо * (1 - Pо ) / n]

= 0.83 - 0.71 / [√(0.71 * 0.29) / 110]

= 0.12 / 0.043265

= 2.77360453

Test statistic = 2.77

c) P-value

P(z > 2.77) = 2 * [1 - P(z < 2.77)] = 2 * 0.0028

P-value = 0.0056

∝ = 0.01

P-value < ∝

Reject the null hypothesis.  There is sufficient evidence to support the researchers claim at the 1% significance level.

a parallelogram has one angle that measures 55 degrees. what are the measures of the other angles in the parrelogram.
Ugo [173]

a parallelogram has four sides so all its angles add up to make 360

the angle across from the 55 would also be a 55 equaling a 110 degrees angle leaving you with 250 so your other two angles both equal 125
