|-13| is a absolute value so it cant be negative so 13 plus 0 equals 13.

tankabanditka [31]

Answer:

2 raisins.

Step-by-step explanation:

Let x represent total number of required ingredient.

We have been given that Ren finds 6 peanuts, 4 raisins, 3 cranberries, and 5 chocolate chips in a handful of trail mix. We are asked to find of which ingredient Ren will have 2 pieces for a total of 9 pieces.

First of all, we will find total number of ingredients by adding each ingredient as:

$\text{Total number of ingredients}=6+4+3+5$

$\text{Total number of ingredients}=18$

Now, we will use ratio to solve for our given problem as:

$\frac{\text{Required ingredient}}{\text{Total ingredient}}=\frac{2}{9}$

$\frac{x}{18}=\frac{2}{9}$

$\frac{x}{18}\cdot 18=\frac{2}{9}\cdot 18$

$x=\frac{2}{1}\cdot 2$

$x=4$

Since there are 4 raisins, therefore, for every 9 pieces in Ren's handful of trail mix there are 2 raisins.

Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil.

oksian1 [2.3K]

Answer:

0.36 = 36% probability that the land has oil and the test predicts it

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

45% chance that the land has oil.

This means that $P(A) = 0.45$

He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.

This means that $P(B|A) = 0.8$

What is the probability that the land has oil and the test predicts it?

This is $P(A \cap B)$ . So

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$P(B \cap A) = P(B|A)*P(A) = 0.8*0.45 = 0.36$

0.36 = 36% probability that the land has oil and the test predicts it
