I really dont understand what your asking, but probably 75%

Hey You!

It's just asking, '150 is what percent of 200?'

150 / 200 × 100 = 75

So, 150 miles is 75% of 200 miles.

Find the solution(s) of the quadratic equation 2x2 – 3x – 35 = 0

Yuliya22 [10]

Answer: x = 5, x = -7/2

Step-by-step explanation:

2x² - 3x - 35 = 0

Step 1: Find two values whose product = 2(-35) and sum = -3: -10 & 7

Step 2: Replace the b-value of -3x with -10x + 7x:

2x² - 10x + 7x - 35 = 0

Step 3: Factor the first two terms and the second two terms:

2x(x - 5) +7(x - 5) = 0

Step 4: Write the factored form:

Notice that the parenthesis are identical. This is one of the factors. The outside values are the other factor:

Parenthesis: (x - 5)

Outside: (2x + 7)

Factored form: (x - 5)(2x + 7) = 0

Step 5: Set each factor each to zero and solve for x:

x - 5 = 0 2x + 7 = 0

x - 5 $x=-\dfrac{7}{2}$

If you ride a pterodactyl for 3 hours at 10 mph and then ride a stegosaurus for 1 hour at 2 mph, what would be your average spee

g100num [7]

Answer:

8 mph

Step-by-step explanation:

The equation for average speed is:

$average\ speed=\frac{total\ distance}{total\ time}$

Let's start by finding the distance for each animal:

$d=st\\d=3h*10\frac{m}{h}\\d=30m$

$d=st\\d=1h*2\frac{m}{h}\\d=2m$

Now, we can find the average speed:

$average \ speed=\frac{30mi+2mi}{3hr+1hr}=\frac{32mi}{4hr}=8\frac{mi}{h}$

8 mph

How to find the mean of a probability distribution?

e-lub [12.9K]

That depends. If you have a finite data set, you would add up all the points you have and divide by the total count.

Or, if you are working with pure distributions, the mean is the same as the expected value of the corresponding random variable.

Suppose you have a discrete random variable $X$ with a given probability mass function $f_X(x)$ , then the mean is given by

$\mathbb E(X)=\displaystyle\sum_xxf_X(x)$

which would mean you take all the possible probability for the event that $X=x$ , multiply each by that $x$ , and add them together.

If the distribution is continuous, say a random variable $Y$ that has probability distribution function $f_Y(y)$ over some support $S$ , then the mean is

$\mathbb E(Y)=\displaystyle\int_Syf_Y(y)\,\mathrm dy$
