How can I find the missing values to complete the table? I am a bit confused.

To find the missing values, find the slope of the equations. Since both equations are linear, we know that the slope is linear. We can find the slope of the equations by using the equation for slope.

Slope for Y1:
m = (y2 - y1) / (x2 - x1) = (11 - 15) / (-3 - -5) = -4 / 2 = -2

Therefore, for Y1, you can subtract 2 from each previous answer to fill in the column. So underneath 15 would be 13, then 11, then 9, etc.

Slope for Y2:
m = (y2 - y1) / (x2 - x1) = (-12 - -15)) / (-4 - -5) = 3 / 1 = 3

<span>Therefore, for Y2, you can add 3 from each previous answer to fill in the column. So underneath -15 would be -12, then -9, then -6, etc.</span>

Ok. To convert anything into anything else you do something very very simple. Divide what you want...by what you have. For example, if I have 15 liters of water, I'm going to multiply by gallons over liters. Multiply the measurement given by what you want, then divide that by what you have.

You take the higher unit and make that 1, then however many of the other units you can fit and that's the other number. That can become 1 gallon / 3.79 liters, or 30m / 3000cm, etc.

So you have 15 liters, you want it in gallons, and it takes four gallons per liter:

15 liters x 1 / 3.79

= 4 gallons (3.9577836 gallons unrounded)

This works because you are dividing the measurement given by how many units of that measurement it takes to fit in another measurement. However, I prefer this method because it makes it easier to figure out when to multiply into smaller units, or divide to get bigger units.

How to convert: measurement x want / have

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.

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

I find it useful to use a graphing calculator to find the zeros of higher-order polynomials. Once you find one or more rational zeros, you can factor them out to find the reduced polynomial factors (or you can use synthetic division).

1. This factors as (5x+2)(3x-1)(x-8). Roots are {-2/5, 1/3, 8}

2. This factors as (x-9)(x²-5x+2). Roots are {2.5-√4.25, 2.5+√4.25, 9}

3. This factors as (x-6)(5x²+3x+1). Roots are{-0.3-i√0.11, -0.3+i√0.11, 6}

Answer:

x= 12.9 (3 s.f.)

Step-by-step explanation:

Please see attached picture for full solution.

1. Label the hypotenuse, adjacent and opposite side of the triangle.

2. Look at the given information.

3. Decide if you should use sine, cosine or tangent.

sine angle= opp/hyp

cosine angle= adj/hyp

tangent angle= opp/adj
