Answer:

The correct answer is $y-5=4(x+3)$ .

Step-by-step explanation:

The point-slope form of the equation of a straight line is:

$y - y_1 = m(x - x_1)$

The equation is useful when we know:

one point on the line: $(x_1,y_1)$
and the slope of the line: $m$ .

We know that the point is (−3,5) and the slope is 4.

Applying the above definition we have that

$y-5=4(x+3)$

hoa [83]

Well, I might not be correct but
To find the answer you first have to divide 2,000 by 10 because if will show you how many baseball cards are in his collection. Because it is 1/10
Then you have your answer. Sorry if wrong

Suppose that contamination particle size (in micrometers) canbe modeled as

asambeis [7]

Answer:

c) 2

d) 0.96

Step-by-step explanation:

We are given the following in the question:

$f(x) = 2x^{-3}, x > 1\\~~~~~~~= 0, x \leq 1$

a) probability density function.

$\displaystyle\int^{\infty}_{\infty}f(x) dx = 1\\\\\displaystyle\int^{\infty}_{-\infty}2x^{-3}dx = 1\\\\\displaystyle\int^{\infty}_{1}2x^{-3}dx\\\\\Rightarrow \big[-x^{-2}\big]^{\infty}_1\\\\\Rightarrow -(0-1) = 1$

Thus, it is a probability density function.

b) cumulative distribution function.

$P(X$

c) mean of the distribution

$\mu = \displaystyle\int^{\infty}_{-\infty}xf(x) dx\\\\\mu = \int^{\infty}_12x^{-2}dx\\\\\mu = (-\frac{2}{x})^{\infty}_{1}\\\\\mu = 2$

d) probability that the size of random particle will be less than 5 micrometers

$P(X$

18 POINTS<br><br><br> What are the 5 properties of a Parallelogram?

kap26 [50]

Answer:

There are six important properties of parallelograms I know:

Opposite sides are congruent (AB = DC).

Opposite angels are congruent (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

The diagonals of a parallelogram bisect each other

In the equation x=−3y, what is the unit rate?

Paul [167]

The unit rate is -1/3.

In direct variation, y varies directly to x by a constant ratio k.

Its equation looks like this: y = kx ; where k stands for the constant ratio.

In the above equation. x = -3y, it should be converted to the proper equation. both sides must be transferred and its accompanying sign must be changed.

3y = -x
3y/3 = -x/3
y = (-1/3)x
where: y is the total value; -1/3 is the unit rate; and x is the number of units
