Step-by-step explanation:

The complete question is as follows;

For 100 births, P(exactly 56 girls = 0.0390 and P 56 or more girls = 0.136. Is 56 girls in 100 births a significantly high number of girls? Which probability is relevant to answering that question? Consider a number of girls to be significantly high if the appropriate probability is 0.05 or less V so 56 girls in 100 birthsa significantly high number of girls because the relevant probability is The relevant probability is 0.05

Solution is as follows;

Here. we want to know which of the probabilities is relevant to answering the question and also if 56 out of a total of 100 is sufficient enough to provide answer to the question.

Now, to answer this question, it would be best to reach a conclusion or let’s say draw a conclusion from the given information.

WhWhich of these four sets of side lengths will form a right triangle? Set 1 10 cm, 26 cm, 24 cm Set 2 4 in., 2 in., 6 in. Set 3
Aloiza [94]

Answer:

All four Sets didn't work

Step-by-step explanation:

You should be doing hypothnose aka: a² + b² = c²

If they both equal that means they are a right triangle.

Set 1:

24² + 26² = 110²

576 + 676 = 10²

1252 = 12100

No

Set 2:

2² + 4² = 6²

4 + 16 = 6²

20 = 36

No

Set 3:

13² + 14² = 15²

169 + 196 = 15²

365 = 225

No

Set 4:

10² + 20² = 30²

100 + 400 = 30²

500 = 900

No

SMART PEOPLES HELP ME ASAP
inysia [295]

Answer:

35 degrees

Step-by-step explanation:

The angle is given to be a right angle by the red square. The right angle is intercepted by a line. One side of the whole 90 degree angle is said to be 55 degrees. Both sides should equal 90 degrees if added.

This means that to find the missing angle, you would subtract 55 degrees from 90 degrees to get 25 degrees.
