What is the answer? X/8 - 4 = 15/16

sukhopar [10]

Answer:

<h2>x = 39.5</h2>

Step-by-step explanation:

$\dfrac{x}{8}-4=\dfrac{15}{16}\qquad\text{multiply both sides by 8}\\\\8\!\!\!\!\diagup^1\cdot\dfrac{x}{8\!\!\!\!\diagup_1}-(8)(4)=8\!\!\!\!\diagup^1\cdot\dfrac{15}{16\!\!\!\!\!\diagup_2}\\\\x-32=\dfrac{15}{2}\qquad\text{add 32 to both sides}\\\\x-32+32=7.5+32\\\\x=39.5$

The following table provides a probability distribution for the random variable y. Y f(y) 1 0. 20 5 0. 30 6 0. 40 9 0. 10 (a) co

Vitek1552 [10]

The probability distribution table is used to represent individual probabilities

The value of E(y) is 5.0

<h3>How to compute e(y)?</h3>

The value of e(y) is calculated using the following expected value formula

$E(y) = \sum y * P(y)$

So, we have:

$E(y) = 1 * 0.20 + 5 * 0.30 + 6 * 0.40 + 9 * 0.10$

Evaluate

$E(y) = 5.0$

Hence, the value of E(y) is 5.0

The wall is 4m long and 3m board.If it has volume of 720000cm.find the height of the wall

OLEGan [10]

Answer:

Step-by-step explanation:

l = 4m = 400 cm

w = 3m = 300 cm

Volume = 720000 cubic cm = 720000

length * width * height = 720000

400 * 300 * height = 720000

height = 720000 / 400 * 300 = 72/12 = 6 cm
