What is the first error Alycia made in her proof.

Mathematics

Answer: Alycia only established some of the necessary conditions for a congruence criterion.

Step-by-step explanation: Two triangles are <u>congruent</u> if their corresponding sides or/and corresponding angles are the same.

There are 5 ways to find out if the triangles are congruent.

The one Alycia used seems to be the one called <u>Side-Angle-Side</u>, which states that if two sides and its included angle is equal to the corresponding sides and angle of the other triangle, they are congruent.

For triangles ΔOPQ and ΔSTR to be congruent, using that theorem:

1) ∠O = ∠S

2) OP = TS

And

3) RS = OQ

So, Alycia's error is that she didn't prove RS = OQ, which would definitively  conclude that both triangles are congruent.

Which of these is most likely a pair of independent variables? a person’s income and savings the price of steel and the price of
Vikki [24]
Independent variables are things that can stand alone. Which set of these variables does not rely on each other?  For example the income and savings. I want 1,000,000 in my savings account, however my income is not nearly that high since I only make 19,000. Look at the other pairs and see if there is a correlation between them.

I got number 7 wrong can someone help me with the answer and the work
Amiraneli [1.4K]
To figure out this problem break it down into steps.

We know that there are 1 - 25 or 25 cards in total, one card is taken out and not replaced so now there are only 24 cards.

25 - 1 = 24.

Find the probability of getting one number greater than 10, this would be all numbers from 10 - 25, which are 25 - 10 = 15 options to choose that will give you a value greater than 10.

Probability = 15/24 = 5/8.

For 2 cards simply multiply the probability by itself to get 2 cards where the number is greater than 10.

5/8 • 5/8 = 25/64.

The probability of getting 2 cards that are greater than 10, are 25/64.

This is the solution.

koban [17]

Answer:

Step-by-step explanation:

Well we can find how far he travels in 55 seconds if he swims at constant speed of 5/3 meters.

5/3 times 55 = approx. 91.66 meters

Therefore Xavier will not quality for the national Swim Meet because he didn't swim 100 meters in 55 seconds
