The two legs of a right triangle are the same length. the hypotenuse is 7 meters long. find the length of the legs. express your answer in simplified radical form, or as a decimal rounded to four places.

let

x> the length side of the legs of a right triangle

H> hypotenuse

we /know that

in a right triangle

Applying the Pythagorean Theorem

H²=x²+x²>H²=2x²> solve for x> x=H/√2

H=7 m

so

x=7/√2>(7√2) /2 m> 4.9497 m

the answer is

in simplified radical form> (7√2) /2 m

as a decimal rounded to four places>4.9497 m

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
