.5 because 100/2 is 50 and there’s 1.00 and when you divide that it’s .5

Archy [21]

Answer:

$a) \: - 2x + 4 = 10 \\ 4 = 10 + 2x \\ 4 - 10 = 2x \\ - 6 = 2x \\ \frac{ - 6}{2} = x \\ - 3 = x \: or \: x = - 3 \\ \\ b) \: \frac{3}{4x} = 2 \\ 3 = 2 \times 4x \\ 3 = 8x \\ x = \frac{3}{8} \\ 0.375 = x \: \: or \: x = 0.375$

4(a + 2) = 14 – 2(3 – 2a) –2 –1 no solution all real numbers

Ray Of Light [21]

All real numbers.

$\boxed{TRUE}$

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

Expand: 4(a+2)=4a+8

Expand again: 14-2(3-2a)=4a+8

4a+8=4a+8

You subtract by 8 from both sides of an equation.

4a+8-8=4a+8-8

Simplify.

4a=4a

Then, subtract by 4a from both sides of an equation.

4a-4a=4a-4a

Finally, simplify.

4a-4a=0

0=0

True

All real numbers is the final answer.

Hope this helps you!

Have a nice day! :)

Suppose the correlation between height and weight for adults is +0.40. What proportion (or percent) of the variability in weight

Schach [20]

Answer:

We are given the correlation between height and weight for adults is 0.40.

We need to find the proportion of the variability in weight that can be explained by the relationship with height.

We know that coefficient of determination or R-square measures the proportion or percent of variability in dependent variable that can be explained by the relationship with independent variable. There the coefficient of determination is given below:

$R^{2}=r^{2}=0.40^{2}=0.16$

Therefore, the 0.16 or 16% of the variability in weight can be explained by the relationship with height
