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.

mafiozo [28]

Answer:

\lim_{x \to 2} (x+1)(3x^2-9) = 9

Step-by-step explanation:

Step 1: Write out limit

\lim_{x \to 2} (x+1)(3x^2-9)

Step 2: Evaluate

(2 + 1)(3(2)² - 9)

3(3(4) - 9)

3(12 - 9)

3(3)

Two trains, Train A and Train B weigh a total of 349 tons. Train A is heavier than Train B. The difference in their weights is 2
Ainat [17]

Answer:

Train A = 299 tons Train B = 50 tons

Step-by-step explanation:
Train A = x

Train B = y

x+y = 349

x= y +249

Plug in one equation into another

y+249+y= 349

Simplify

2y+249=349

Subtract 249 from both sides

2y=100

Divide both sides by 2

y=50

Plug it into the x equation to solve for x

x+50=349

-50 from both sides

x=299

Let W= { (x, y, z) |x=1|; y, z ∈ℝ } Prove that W is a subspace of ∈ℝ<br> How can I resolve this ?
Nataly [62]

Answer:

W is not a subspace.

Step-by-step explanation:

Notice that (-1,2,2) and (-1,5,3) are both elements of W. Because its x coordinate, x = -1, satisfy the condition |x| = 1.

but (-1,2,2) + (-1,5,3) = (-2,7,5) do not belongs to W. Because its first coordinate, x =-2, do not satisfy |x| = 1.

Select all the terms that are like terms.
timama [110]

Answer:

-8 x2

1.25 x2

x2

Step-by-step explanation:

Like terms are those which have the same variable. For example x²= x ² but x³≠x² functions having the same variable are called like terms. Terms vary with the change in exponents.

-8 x2

1.25 x2

x2

These three are like terms because they have the same variable with the same exponent.

The following are not like terms. They are unlike terms each having a different variable with a different exponent.

5 yx2

-3.4 x3

4 x

5

Like terms         -8 x2       1.25 x2          x2

Unlike terms :5 yx2             -3.4 x3           4 x                   5
