what is the point slope form of an equation with the slope of 3/5 that passes through the point (10,-2)?
Mama L [17]
Point slope form of a line:
y-y_1=m(x-x_1) where m is your slope and (x_1,\ y_1) is a point on your line.

For a line with a slope of 3/5 that passes through (10, -2)...
m=\frac35,\ x_1=10,\ y_1=-2
Let's plug these values into our formula.

y-(-2)=\frac35(x-10)

Subtracting by a negative is the same thing as adding (the double negatives cancel), so let's simplify that.

\boxed{y+2=\frac35(x-10)}

There's our equation in point-slope form. (keep in mind that you're not going to want to distribute that 3/5 or subtract the 2 or anything. You want to keep it similar to the formula.

Researchers have discovered a new genetic marker for a form of cancer. Twelve percent of the overall population carry this marke
In-s [12.5K]

Answer:

The probability that a person with the marker develops cancer is 0.0725.

Step-by-step explanation:

Let's denote the events as follows:

<em>A</em> = a person has cancer

<em>B</em> = a person carries the marker.

<u>Given:</u>

P (A) = 0.03

P (B) = 0.12

P (B|A) = 0.29

The conditional probability of an event <em>X</em> provided that another event <em>Y</em> has already occurred is:

P(X|Y)=\frac{P(Y|X)P(X)}{P(Y)}

Use the conditional probability formula to compute the probability that a person with the marker develops cancer.

P(A|B)=\frac{P(B|A)P(A)}{P(B)} =\frac{0.29\times0.03}{0.12}=0.0725

Thus, the probability that a person with the marker develops cancer is 0.0725.

What is the value of Cos n 2π=???
faust18 [17]
If n is an integer, then cos(n(2<span>π))=1.

Take n=0, cos(2</span>π)=cos(0)=1, n=1, cos(2π)=1, n=2, cos(2(2π))=cos(4<span>π)=cos(0)=1...

If n is not an integer, well, ..... we don't know the value, which depends on the value of n.</span>
