If x+3/3 = y+2/2, then x/3 = ________ it's not multiple choice.

2 answers:

Sorta speculating here but I believe its y/2

If you have x+3/3 = y+2/2 you can simplify to x/3 = y/2

I'm not sure what you're learning or what you're teacher wants you to learn but this is the simplest answer I can think of.

Answer:

y/2

Step-by-step explanation:

(x+3-3)/3=(y+2-2)/2 adding the denominator to numerator

x/3=y/2

Dimas [21]

Answer:

v=0

Step-by-step explanation:

Solve what is in the parentheses, then the exponents: 12v+10=64v+10

Subtract 64v from both sides: -52v+10=10

Subtract 10 from both sides: -52v=0

Divide by -52: v=0

A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtain

Ivanshal [37]

Answer:a-396

b-420

Step-by-step explanation:

$\alpha$ =0.1

Margin of Error=0.04

Level of significance is z $\left ( 0.1\right )=1.64$

Previous estimate $\left ( p\right ) =0.38$

sample size is given by:

n= $\left (\frac{Z_{\frac{\alpha }{2}}}{E}\right )p\left ( 1-p\right )$

n= $\frac{1.64}{0.04}^{2}0.38\left ( 1-0.38\right )=396.0436\approx 396$

$\left ( b\right )$ Does not use prior estimate

Assume

$\alpha$ =0.1

Margin of Error=0.04

Level of significance is z $\left ( 0.1\right )=1.64$

Population proportion $\left ( p\right )$ =0.5

n= $\left (\frac{Z_{\frac{\alpha }{2}}}{E}\right )p\left ( 1-p\right )$

n= $\frac{1.64}{0.04}^{2}0.5\left ( 1-0.5\right )$

n=420.25 $\approx 420$
