Which two triangles are congruent by ASA? Explain.

yarga [219]

Answer:

OGH and TCA

Step-by-step explanation:

that's quite easy...

the congruency criterion is ASA or Angle side Angle.

i.e. a side lying between two Angles.

so we have

GH = FN= CA

now, G=I= C

and H=N=A

it's pretty clear that G-GH-H = C-CA-A

(just to explain)

hence, the answer

the numbers 2-12 are written on cards and placed in the bag.what is the probability of picking an even number then replacing it

lorasvet [3.4K]

We have the cards numbered as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.

Sample number is, n(S)=11.

We pick a card and want to get even number like 2, 4, 6, 8, 10, and 12.

Probability of picking an even number would be :-

P(even numbers) = $\frac{6}{11}$

Now we replace the card and want to get a 7 in second attempt.

Probability of picking a 7 would be :-

P(number 7) = $\frac{1}{11}$

Now Probability of this event = P(even numbers) × P(number 7)

Probability = $(\frac{6}{11} )(\frac{1}{11} ) = \frac{6}{121}$

So final answer is $\frac{6}{121}$ .

PLEASE HELP THIS IS DUE IN A FEW MINUTES PLEASE I WILL MARK YOU BRAINLIEST!!

Lady bird [3.3K]

Answer:

7. MN = 12

8. m<XYZ = 90°

9. m<YXM = 49°

10. m<XWZ = 131°

Step-by-step explanation:

This drawing is messed up.

The perspective is off because <NMW looks to be an obtuse angle because it appears to be greater than a square angle or 90°.

The median should be accurate in perspective even though WZ appears to be greater than MN or XY which is greater than WZ but appears to be smaller than WZ.

In estimating the mean score on a fitness exam, we use an original sample of size n 3 and a bootstrap distribution containing 50

maw [93]

Answer:

C) 67.5 to 72.5

Step-by-step explanation:

The value to calculate the confidence interval is given as:

$(x-z_{\frac{\alpha}{2}} \times \frac{\sigma}{\sqrt{n}},x-z_{\frac{\alpha}{2}} \times \frac{\sigma}{\sqrt{n}})$

Margin of error is given by:

$z_{\frac{\alpha}{2} } \times \frac{\sigma}{\sqrt{n}}$

Using a sample of size n = 3, with 95% confidence the confidence interval came out to be 67 to 73.

We need to identify the new confidence interval if the sample size is increased to n = 16

If you observe the formula, you will see that the sample size(n) is in the denominator. This means, if value of n will be increased the value of fraction will be decreased, which will result in an overall smaller value of margin of error. Since, margin of error is smaller, the values of confidence interval will be closer to the mean.

From here, we can conclude that if sample size is increased, the confidence interval will get narrower. From the given options only option C contains a narrow confidence interval. Therefore, correct answer will be option C: 67.5 to 72.6
