Jason tossed a fair coin 3 times. What is the probability of getting a head and two tails in any order?

1 answer:

6 0

Coins Tossed three times.
Sample = [HHH] [HHT] [HTT] [TTT] [TTH] [THH] [HTH] [THT]

Events with 1 Head and Two Tails = [HTT] [TTH] [THT] = 3

P = 3/8

In short, Your Answer would be: 3/8

Hope this helps!

liubo4ka [24]

ANSWER:

The average burnout time of a large number of bulbs has a sampling distribution that is close to Normal.

STEP-BY-STEP EXPLANATION:

The cental limit theorem states, that id the sample size is large (30 or more), then the sampling distribution of the sample means is approximately normal with mean ц and standar deviation б/ $\sqrt{n}$

Thus the correct answer is the average burnout time of a large number of bulbs has a sampling distribution that is close to Normal.

Sketch the equilibrium solutions for the following DE and use them to determine the behavior of the solutions.

GREYUIT [131]

Answer:

$y=\dfrac{1}{1-Ke^{-t}}$

Step-by-step explanation:

Given

The given equation is a differential equation

$\dfrac{dy}{dt}=y-y^2$

$\dfrac{dy}{dt}=-(y^2-y)$

By separating variable

⇒ $\dfrac{dy}{(y^2-y)}=-t$

$\left(\dfrac{1}{y-1}-\dfrac{1}{y}\right)dy=-dt$

Now by taking integration both side

$\int\left(\dfrac{1}{y-1}-\dfrac{1}{y}\right)dy=-\int dt$

⇒ $\ln (y-1)-\ln y=-t+C$

Where C is the constant

$\ln \dfrac{y-1}{y}=-t+C$

$\dfrac{y-1}{y}=e^{-t+c}$

$\dfrac{y-1}{y}=Ke^{-t}$

$y=\dfrac{1}{1-Ke^{-t}}$

from above equation we can say that

When t will increases in positive direction then $e^{-t}$ will decreases it means that ${1-Ke^{-t}}$ will increases, so y will decreases. Similarly in the case of negative t.

<h3>Inequality</h3>

An inequality is a relation between two numbers and/or expressions that are related via <, >, ≥ or ≤ sign.

A strict inequality is an expression that uses < and >. It tells us that one side is only more or less than the other side.

When 2 simple inequalities are joined by or and, we get a compound inequality.

When solving an inequality, the solution will be a range of values called its solution sets. The inequality will remain true for every single value in this range.

The inequality signs are;

Greater than >
Less than <
Greater than or equal to ≥
Less than or equal to ≤
Equal to =

Answer:

93.15

Step-by-step explanation:

Multiply 230.00 dollars and 0.55 = 126.50

Subtract 230.00 dollars and 126.50 = 103.50

Multiply 103.50 and 0.10 = 10.35

Subtract 103.50 and 10.35 = 93.15
