2(2 – 2x) = –3x A. –4 B. 4 C. 6 D. 0
zlopas [31]

Answer:

x = 4

Step-by-step explanation:

Let's solve:

2(2−2x)=−3x

Step 1: Simplify both sides of the equation.

2(2−2x)=−3x \\ (2)(2)+(2)(−2x)=−3x(Distribute) \\ 4+−4x=−3x \\ −4x+4=−3x

Step 2: Add 3x to both sides.

−4x+4+3x=−3x+3x \\ −x+4=0

Step 3: Subtract 4 from both sides.

−x+4−4=0−4 \\ −x=−4

Step 4: Divide both sides by -1.

\frac{ - x}{ - 1}  =  \frac{ - 4}{ - 1}

Therefore, the answer will be x = 4.

lidiya [134]

Answer:

d. 20

Step-by-step explanation:

Standard deviation is 4.5

Margin error for the problem is 2 hours

Probability 95%, that means that the siginficance level α is 1 – p

α = 1 – 0.95 = 0.05

margin of error (ME) can be defined as follows

ME = Z(α/2) * standard deviation/ √n

Where n is the sample size

Z(0.05/2) = Z(0.025)

Using a z table Z = 1.96

Now, replacing in the equation and find n

2 = 1.96 * 4.5/ √n

2 = 8.82/√n

√n = 8.82/2

√n = 4.41

n = 4.41^2

n = 19.44 ≈ 20
