Answer:

Step-by-step explanation:

9x+(5y+x)-3y

Remove the parenthesis

When there is a "+" in front of an expression in parentheses, the expression remains the same

9x+5y+x-3y

Collect like terms

(9x+x)+(5y-3y)

10x+2y

Answer:

C and D

Step-by-step explanation:

Let's add this all together.

9x + 5y + x - 3y

Combine like terms 5y + -3y and 9x + x

10x + 2y

So we know D is at least correct.

What else? C is also correct, because we can expand it outward.

10x + 5y - 3y = 10x + 2y

A and B are not correct! We can't multiply the ys or the xs.

GarryVolchara [31]

Answer:

$P(X>300)$

And we can find this probability with the complement rule:

$P(X>300)= 1-P(X$

Step-by-step explanation:

For this case we define the random variable X ="driving distance for the top 100 golfers on the PGA tour" and we know that:

$X \sim Unif (a=284.7, b=310.6)$

And for this case the probability density function is given by:

$f(x) =\frac{1}{310.6 -284.7} =0.0386 , 284.7 \leq X \leq 310.6$

And the cumulative distribution function is given by:

$F(x) =\frac{x-284.7}{310.6-284.7} , 284.7 \leq X \leq 310.6$

And we want to find this probability:

$P(X>300)$

And we can find this probability with the complement rule:

$P(X>300)= 1-P(X$

Answer: undefined

Step-by-step explanation:

The answer is undefined because when you plug in the points in the formula

y2-y1/ x2-x1 the denominator is 0 which makes it undefined. Also when you put it into a graphing calculator it will say that its undefined.
