Find the measure of angle 3=

Mathematics
1 answer:
andre [41]3 years ago
5 0

Answer: <em>50°</em>

Step-by-step explanation:

<em>Since angle 3 is in a right triangle we can assume one angle is 90°</em><em> </em><em>and then the other missing angle will be 40°</em>

<em>Because you take 180°-140°(the angle next to it) which will equal 40°</em>

<em>Now every triangle must add up to 180°</em>

<em>so lets take the angles we have now</em>

<em>90° +40°=130°</em>

<em>now take that 130°</em>

<em>180°-130°=</em><em>50°</em>

<em>Now check your work</em>

90°+40°+50°=180°

Angle 3 is 50°

How many times can 2 1/2 be subtracted from 12 1/2
Luba_88 [7]
2 1/2 = 2.5
12 1/2 = 12.5

This means you can calculate how may times it goes in by dividing it and rounding the number down:

12.5 / 2.5 = 5

*5 can not be rounded down so it stays the same

This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)

For 100​ births, P(exactly ​girls) and ​P( or more ​girls). Is girls in 100 births a significantly high number of​ girls? Which
madreJ [45]

Answer;

The relevant probability is 0.136 so the value of 56 girls in 100 births is not a significantly high number of girls because the relevant probability is greater than 0.05

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.

The relevant probability is 0.136 so the value of 56 girls in 100 births is not a significantly high number of girls because the relevant probability is greater than 0.05

Solve: 2x + 18 - 1 = 33
Alecsey [184]

Answer: x=8

<u>Simplify both sides of the equation</u>

<u />2x+18+-1=33<u />

<u />(2x)+(18+-1)=33(Combine Like Terms)

2x+17=33

<u>Subtract 17 from both sides</u>

<u></u>2x+17-17=33-17\\2x=16<u></u>

<u></u>

<u>Divide both sides by 2</u>

<u></u>2x/2=16/2\\x=8<u></u>
