PLEASE HELP WILL GIVE BRAINLIEST

Mathematics
1 answer:
OlgaM077 [116]3 years ago
5 0

Answer:

G

Step-by-step explanation:

"Any particular event either (a) will happen or (b) won't happen."

That statement above is a certainty, probability = 100% = 1

This means the probability that event E <u>will </u>happen plus the probability that even E <u>won't </u>happen must add up to 100% = 1

So we can always say -->  prob(E) + prob (not E) = 1

The probability you will roll a 5 on a fair, six-sided die is 1/6.

So we use that to find the probability of not rolling the 5.

1/6 + prob(not E) = 1

   prob(not E) = 1 - 1/6  <---- This is answer G

    prob(not E) = 5/6

Hope this helps.

Find the equation of the normal of the curve at the given points :D thankiewss
Ahat [919]
We want to find the equation of the normal line of y=\dfrac{20-x}{3x} at the point P=(x_0,y_0), where y_0=3. First calculate x_0. We have:

y_0=f(x_0)=\dfrac{20-x_0}{3x_0}\\\\\\3=\dfrac{20-x_0}{3x_0}\quad|\cdot3x_0\\\\\\3\cdot3x_0=20-x_0\\\\9x_0=20-x_0\\\\9x_0+x_0=20\\\\10x_0=20\quad|:2\\\\\boxed{x_0=2}

Now, when we know that P=(x_0,y_0)=(2,3) we can write an equation of the normal line as:

\boxed{y-y_0=-\dfrac{1}{f'(x_0)}(x-x_0)}

Calculate f'(x_0):

f'(x)=\left(\dfrac{20-x}{3x}\right)'=\left(\dfrac{20}{3x}\right)'-\left(\dfrac{x}{3x}\right)'=\dfrac{20}{3}\cdot\left(\dfrac{1}{x}\right)'-\left(\dfrac{1}{3}\right)'=\\\\\\=\dfrac{20}{3}\cdot\left(-\dfrac{1}{x^2}\right)-0=\boxed{-\dfrac{20}{3x^2}}\\\\\\\\f'(x_0)=f'(2)=-\dfrac{20}{3\cdot2^2}=-\dfrac{20}{3\cdot4}=-\dfrac{20}{12}=\boxed{-\frac{5}{3}}

and the equation of the normal line:

y-y_0=-\dfrac{1}{f'(x_0)}(x-x_0)\\\\\\y-3=-\dfrac{1}{-\frac{5}{3}}(x-2)\\\\\\y-3=\dfrac{3}{5}(x-2)\\\\\\y-3=\dfrac{3}{5}x-\dfrac{6}{5}\\\\\\y=\dfrac{3}{5}x-\dfrac{6}{5}+3\\\\\\\boxed{y=\dfrac{3}{5}x+\dfrac{9}{5}}

In a class 5/8 of pupils are boys.If 15 girls are in that class how many boys are there​
Kobotan [32]

Answer:

25

Step-by-step explanation:

If 5/8 are boys then

1 - 5/8 = girls

3/8 = girls

3/8 of the total are girls

Let x = total

3/8 ( x) = 15

8/3 * 3/8 * x = 15 * 8/3

x = 40

There are 40 total students

5/8 are boys

5/8 * 40

25 are boys
