SSS theorem: If two triangles have three pairs of sides in the same ratio, then the triangles are similar.
Write the ratio between the smallest sides, between the greatest sides and between the middle sides and compare the results:
This gives you that
By SSS theorem triangles ABC and EFG are similar with scale factor 180.
Answer:
A
Step-by-step explanation:
A constant line looks like a flat line with a slope of 0.
Answer:
The entire population will have a mean difference of μD = 0.
Step-by-step explanation:
This case is a null hypothesis for a test of repeated measures of two tails. The general null hypothesis is a hypothesis of no difference. We must find the differences of each pair and then find the mean of these differences.
Under a null hypothesis it is established that the population mean of the differences is 0.
Therefore, the correct option is the entire population will have a mean difference of μD = 0 (first option).
Second option is incorrect: It considers the sample instead of the population.
Third option is incorrect: It says that the mean difference is different from zero.
Forth option is incorrect: It says that the mean difference is different from zero.

Answer:
- <u><em>Rounding to nearest tenth of centimeter, the ball bounces 192.1 cm high on the 5th bounce.</em></u>
<u><em></em></u>
Explanation:
The <em>ball is dropped from a height of 900 centimeters</em>.
Since the heights form a <em>geometric sequence,</em> you can find a common ratio between consecutive terms. This is:
- Height bounce 2 / height bounce 1 = 560 / 800 = 0.7
- Height bound 3 / height bounce 2 = 392 / 560 = 0.7
Hence, the ratio of the geometric sequence is 0.7, and taking bounce 1 as the start of the sequence, the general term of the sequence is:
With that formula you can find any term:
Rounding to <em>nearest tenth of centimeter</em>, the ball bounces 192.1 cm high on the 5th bounce.
