Answer:

Simone finds safety by leaving in her raft.

P (Safety by waiting for help) = \frac{1}{4} = 0.25

P (Safety by leaving in her raft) = 0.32

0.32 > 0.25

It is more likely that Simone finds safety by leaving in her raft.

Answer:

Finding safety by leaving

Step-by-step explanation:

This was really difficult to read so I'm going to assume that you are supposed to compare 1/4 and .320.

1/4 = .25 < .320

The event with the larger fraction or decimal is more likely.

Show that one zero of 8x230x27 is the square of the other.
murzikaleks [220]

Answer:

8x2-30x+27 has one root (9/4) the square of the other (3/2)

Step-by-step explanation:

8x2+30x+27 = (2*x+3)*(4*x+9)  => solution = {-3/2, -4/9}

One is not the square of the other because squares are positive.

8x2-30x+27 = (2*x-3)*(4*x-9)  =>

solution = {3/2, 4/9}   since (4/9 = (3/2)^2, therefore the preceding question is correct.

15 decreased by twice a number x in algebriac expression
postnew [5]

15 is decreased that is the key word here which indicates subtraction.

twice a number with given variable x is 2x

subtraction always goes behind so 2x - 15
