Bingel [31]

Answer:

N= -44/9 Hope this helped, <3

Step-by-step explanation:

Let's solve your equation step-by-step.

n−2=10n+42

Step 1: Subtract 10n from both sides.

n−2−10n=10n+42−10n

−9n−2=42

Step 2: Add 2 to both sides.

−9n−2+2=42+2

−9n=44

Step 3: Divide both sides by -9.

QUESTION 1 The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards.Assume that the driving

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:

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