If the line goes through the vertical line, that’s your y intercept. Just find the number that it crosses and that your intercept.

Officials begin to release water from a full man-made lake at a rate that would empty the lake in 14 weeks, but a river that can

Margarita [4]

Answer: $\frac{140}{3}$ weeks

Step-by-step explanation:

Given

It takes 14 weeks to empty a lake

also it takes 20 weeks for a river to fill the lake

Part of lake empty in 1 week $=\frac{1}{14}$

Part of lake filled in 1 week is $=\frac{1}{20}$

And if both works simultaneously then

$\frac{1}{14}-\frac{1}{20}=\frac{10-7}{140}$

$=\frac{3}{140}$

therefore it takes $\frac{140}{3}$ weeks to fill it

P( rolling a number greater than 2 and the coin landing on heads or tails)

irina [24]

The value of P(rolling a number greater than 2 and the coin landing on heads or tails) is 4/6

<h3>How to determine the probability?</h3>

The given parameters are:

Objects = Dice and Coin

The sample space of the objects are:

Dice = {1, 2, 3, 4, 5, 6}

Coin = {Head, Tail}

From the above sample spaces, we have:

P(Rolling a number greater than 2) = 4/6

P(Coin landing on heads or tails) = 1

The required probability is then calculated as:

P(rolling a number greater than 2 and the coin landing on heads or tails) = P(Rolling a number greater than 2) * P(Coin landing on heads or tails)

Substitute the known values in the above equation

P(rolling a number greater than 2 and the coin landing on heads or tails) = 4/6 * 1

Evaluate the product

P(rolling a number greater than 2 and the coin landing on heads or tails) = 4/6

Hence, the value of P(rolling a number greater than 2 and the coin landing on heads or tails) is 4/6
