Which side lengths form a right triangle?

Mathematics

3 0

Answer:  A

5,12,13 is a common Pythagorean triple, the second on the list after 3,4,5

B and C aren't on the list, and they would be if they were Pythagorean Triples, which is a list of natural number length sides (a,b,c)  which satisfy the Pythagorean Theorem, a²+b²=c², making them the sides of a right triangle.

Let's verify:

5²+12² = 25+144 = 169 = 13²              √

4²+4² = 16+16 = 32 ≠ 8²                     √

2²+3² = 4+9 = 13 ≠ 4²                         √

Rasek [7]

Answer:

0.6604

Step-by-step explanation:

Given that a market  research firm knows from historical data that telephone surveys have a 36% response rate.

Sample size of random sample = 280

We know for samples randomly drawn of large size sample proportion follows a normal distribution with mean= sample proportin and std error

= \sqrt{\frac{pq}{n} }

Substitute p = 0.36 and q = 1-0.36= 0.64

p follows N with mean = 0.36 and std dev = \sqrt{\frac{0.36*0.64}{\sqrt{280} } } \\=0.0287

Using normal distribution values we can find\

P(33.5p.c. < p < 39pc)\\= P(0.335
