What can you conclude about 3/5 and 60/100 if you know 3/5 is equivalent to 6/10 and 6/10 is equivalent to 60/100
labwork [276]

First we check whether \frac{3}{5} is equivalent to \frac{6}{10}

\frac{3*2}{5*2} = \frac{6}{10}

Both top and bottom are multiplied by 2 to get \frac{6}{10}

So they are equivalent fractions.

Now we check whether \frac{6}{10} is equivalent to \frac{60}{100}

\frac{6*10}{10*10} = \frac{60}{100}

Both top and bottom are multiplied by 10 to get \frac{60}{100}

So they are equivalent fractions.

\frac{3}{5} = \frac{6}{10} =\frac{60}{100}

Hence we conclude that they are equivalent fractions.

svetoff [14.1K]

Answer:

n=(\frac{2.58(1000)}{50})^2 =2662.56 \approx 2663

So the answer for this case would be n=2663 rounded up to the nearest integer

Step-by-step explanation:

We have the following info:

ME = 50 margin of error desired

\sigma = 1000 the standard deviation for this case

The margin of error is given by this formula:

ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}    (a)

And on this case we have that ME =50 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

n=(\frac{z_{\alpha/2} \sigma}{ME})^2   (b)

The critical value for 99% of confidence interval now can be founded using the normal distribution. The significance is \alpha=0.01. And for this case would be z_{\alpha/2}=2.58, replacing into formula (b) we got:

n=(\frac{2.58(1000)}{50})^2 =2662.56 \approx 2663

So the answer for this case would be n=2663 rounded up to the nearest integer

1.<br><br> If sin(-A) = tan 335,3 : A € (-180; 180) then the size of Ais?
Advocard [28]

Answer:

A=-6.746

Step-by-step explanation:

Given that

sin(-A)=tan353.3

A∈(-180, 180)

Required:

Size of A=?

solution:

using calculator we get,

tan(353.3)=-0.117

so sin(-A)=-0.117

now A= Sin^{-1}(-0.117)

A=-6.746
