Answer:
1: 7.5 2: 25 3: 14.2
Step-by-step explanation:
For all of these, you want to use the Pythagorean Theorem, which is a^2+b^2=c^2
1. you would have to plug in 13 for b, and 15 for c, because 15 is the hypotenuse
a^2+13^2=15^2
now, solve for a
a^2+169=225
225-169=56
a^2=56
to undo a squared, you have to take the square root of both sides
sqrt(56) is about 7.5
to check, you would have to plug in 7.5 for a
2. you would start off the same way, but this time we are solving for c
15^2+20^2=c^2
225+400=c^2
625=c^2
take the square root of 625
25 is your answer
if you want to check, plug in 25 for c
3. we are trying to find the hypotenuse again, so we are solving for c
5.1^2+13.2^2=c^2
26.01+174.24=200.25
200.25=c^2
take the square root once again
it is approximately 14.2
if you want to check, plug in 14.2 for c
have a great day!

Step-by-step explanation:
1. X/2 when x = 1/2
Putting value of x in the equation
1/2 /2 = 0.25
2. 2x2 - 8 when x = 3
2(3)2 - 8
= 2(9) - 8
= 18 - 8 = 10
3. 4(x - 7)3 + 5 when x = 9
4 (x3 - 21x2 + 147x - 343) + 5
Putting value of x
4((9)3 - 21(9)2 + 147(9) - 343) + 5
4(729 - 1701 + 1323 - 343) + 5
4(8) + 5
= 32 + 5 = 37

Aimee has 2 sisters in her family. She thinks the probability of a family having 3 children who are all girls is ¼ because there can be 0 girls, 1 girl, 2 girls or 3 girls.
Aimee designs a simulation to test her prediction. She flips a coin 3 times in a row and records the results. She uses heads to represent a girl and tails to represent a boy. After 10 trials of this simulation, Aimee gets the following results.
1 2 3 4 5 6 7 8 9 10
BBB GBB GGG GGB BBG GGB BGG BGB BBG GBB
Does ¼ seem like a reasonable probability of having 3 girls? Use a tree diagram to model and support your thinking.

Answer:
[tex]248[/tex]
Step-by-step explanation:
A=2(wl+hl+hw)=2·(10·4+6·4+6·10)=248
Answer:
ok so first you have to multiple 4 and 6 which is 24 times 2 since there is two small rectangles which is 48
then, multiply 10 with 4 which is 40 times 2 since there is two rectangles is 80
then, 6 times 10 which is 60 times 2 since there is two squares which is 120
and lastly, you add 48 with 80 which is 128 plus 120 which is 248
hope this helps have a good day

Find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards.
Answer:
A deck of cards contains RED cards numbered 1,2 and BLUE cards numbered ... Patricia will draw 8 cards from a standard 52-card deck with replacement. ... Outcome: any of the possible results of an experiment in probability. ... Correct answers:$\frac{7}{9}$7/9 ... Event A: rolling a 6-sided fair number cube and getting 1Step-by-step explanation:
The probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards is 1/26.
To find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards, we need to calculate the probabilities of each event and then multiply them together since the events are independent (the outcome of one event does not affect the outcome of the other event).
1. Probability of rolling an odd number on a fair number cube:
A fair number cube has 6 faces with numbers 1 through 6. Out of these, three numbers are odd: 1, 3, and 5. So, the probability of rolling an odd number is 3/6, which simplifies to 1/2.
2. Probability of drawing a 7 of any suit from a standard deck of cards:
A standard deck of cards has 52 cards. There are four 7s in the deck (one for each suit: hearts, diamonds, clubs, and spades). So, the probability of drawing a 7 is 4/52, which simplifies to 1/13.
Now, multiply the probabilities together:
Probability = (Probability of rolling an odd number) * (Probability of drawing a 7)
Probability = (1/2) * (1/13)
Probability = 1/26
Therefore, the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards is 1/26.

What are the advantages of taking a random sample instead of surveying an entire population?
Answer:
Answer is below
Step-by-step explanation:
Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. Selecting subjects completely at random from the larger population also yields a sample that is representative of the group being studied. This provides lack of bias towards the subject of the survey. It's overall more efficient, faster, and pushes the idea of simplicity through surveys.
Answer:
Simple random sample advantages include ease of use and accuracy of representation. No easier method exists to extract a research sample from a larger population than simple random sampling. It offers a chance to perform data analysis that has less risk of carrying an error. ... There is an equal chance of selection. ... It requires less knowledge to complete the research. ... It is the simplest form of data collection.
