Which equation can be solved by using this system of equations?

startlayout enlarged left-brace 1st row y = 3 x superscript 5 baseline minus 5 x cubed + 2 x squared minus 10 x + 4 2nd row y = 4 x superscript 4 baseline + 6 x cubed minus 11 endlayout

3 x superscript 5 baseline minus 5 x cubed + 2 x squared minus 10 x + 4 = 0

3 x superscript 5 baseline minus 5 x cubed + 2 x squared minus 10 x + 4 = 4 x superscript 4 baseline + 6 x cubed minus 11

3 x superscript 5 baseline + 4 x superscript 4 baseline + x cubed + 2 x squared minus 10 x minus 7 = 0

4 x superscript 4 baseline + 6 x cubed minus 11 = 0

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

85.560%

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
