anzhelika [568]

P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696

Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056

Which method is the most efficient method to use to solve x^2+4x+3=0

Romashka-Z-Leto [24]

Answer:

Factoring

Step-by-step explanation:

To solve the equation $x ^ 2 + 4x + 3 = 0$ , you must apply the factoring method.

You must find two real numbers b and c such that:

$b + c = 4$

and

$b(c) = 3$

Then the expression:

$x ^ 2 + 4x + 3 = 0 = (x + b)(x + c)$

You can prove that:

$b = 3\\c = 1$

$x ^ 2 + 4x + 3 = 0 = (x + 3)(x + 1)$

$(x + 3)(x + 1) = 0$

$x +3 = 0$ or $x + 1 = 0$

$x = -3$ or $x = -1$

Megan hiked 15.12 miles in 6.3 hours. If Megan hiked the same number of miles each hour , how many miles did she hike each hour?

OLEGan [10]

To find how many miles per hour, we divide the number of miles hiked by the number of hours it took to hike them.

=15.12 miles ÷ 6.3 hours
=2.4 miles hiked per hour

Hope this helps! :)
