The only possible methods for determining if the triangles are congruent is SAS, SSS, ASA, AAS, RHS

So you know what answers you can eliminate.

It tells you CA bisects angle BAD. "Bisect" means cut in half equally, so you know that angle CAB and angle CAD is the same. This is angle proof.

Something seems to be cut off from the picture. Depending on what it tells you (for example line xx = line xx), you can figure out the answer.

Answer:

$n=(\frac{1.960(80)}{25})^2 =246.73 \approx 247$

So the answer for this case would be n=247 rounded up to the nearest integer

Step-by-step explanation:

We know that the standard deviation is :

$\sigma = 80$ represent the deviation

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 =25 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 95% of confidence interval now can be founded using the normal distribution and the critical value would be $z_{\alpha/2}=1.960$ , replacing into formula (b) we got:

$n=(\frac{1.960(80)}{25})^2 =246.73 \approx 247$

So the answer for this case would be n=247 rounded up to the nearest integer

What is the product of 2/3 and 4/5?

Paul [167]

Well, product means multiply so we need to multiply these fractions.

2 4
--- x --- =
3 5

now, when you are multipliying fractions you multiply the top and the bottom with the other one.
so 2 times 4 and 3 times 5
and you get
8
--
15

since this fraction can not be simplifyed this is the final answer 8/15
