Makovka662 [10]

Answer:

A is the answer  

12 in

first substitute the variables

then 78=1/2h(5 + 8)

this makes it an equation

add similar terms which equals to

78=1/2xhx13

then divide both sides by 13

6=1/2xh

lastly divide both sides by 1/2

12=h

Step-by-step explanation:

proof

A=1/2x12(5 + 8) then

A=1/2x12x13  then

   A=6x13  then

       A= 78in^2

Considering the given discrete probability distribution, it is found that the expected share is of 10%.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

In this problem, the distribution is given by:

  • P(X = 0.05) = 0.2.
  • P(X = 0.1) = 0.6.
  • P(X = 0.15) = 0.2.

Hence the expected value is given by:

E(X) = 0.2 x 0.05 + 0.6 x 0.1 + 0.2 x 0.15 = 0.1 = 10%.

The expected share is of 10%.

Y=x2-8x-3 standard to vertex form
Drupady [299]

Answer:

  • y = (x - 4)² - 19

Step-by-step explanation:

<u>Standard form of quadratic function:</u>

  • y = ax² + bx + c

<u>Vertex form:</u>

  • y = (x - h)² + k

<u>Convert the given function by completing a square:</u>

y = x² - 8x - 3 =

     x² - 2*4*x + 4² - 4² - 3 =

    (x - 4)² - 19

If 40%of an amount is $24, calculate 100%
Andreas93 [3]
Hey!!

here is your answer >>>

Let's take the total amount as 'X'

Then,

(40/100)X = 24

2x /5 = 24

x = (24*5)/2

x = 12*5

x = 60!.

100% is 60

Hope my answer helps!
