Answer: 25.12 ft

To find the circumference of a circle, multiply the diameter with π (pi)

Formula: 2πr (2 × radius) (π = 3.14)

In the problem...

-----------------------------------------------------------------------------------------------------------------

We can multiply 3.14 by 8 to get the circumference.

3.14 × 8 = 25.12

Hence, 25.12 is the answer, but we can do it another way.

Let me know if you have any questions.

~ Lily, from Brainly.

Note to asker: Hi there, make sure to write down these formulas!

Circumference: 2πr

Area: πr²

Radius: $\frac{diameter}{2}$

Diameter: radius × 2

Have a good day!

Alyssa and Gabriel play the following game. Alyssa rolls a die. If she rolls a 1, 2, or 3, Gabriel gives Alyssa $4. If Alyssa

yulyashka [42]

Answer:

Part a) Alyssa's expectation is equal to $0.33

Part b) Gabriel's expectation is equal to -$0.33

Step-by-step explanation:

we know that

The expected value is the probability of winning multiplied by the value you get when you win, plus the probability of losing multiplied by the value you get when you lose (which is negative as it is a loss).

Part a) Determine Alyssa's expectation

we know that

1) If Alyssa rolls a 1, 2, or 3, Gabriel gives Alyssa $4

The probability is 3/6

we have

$\frac{3}{6}(4)=\$2$

2) If Alyssa rolls a 4, or 5, Gabriel gives Alyssa $1

The probability is 2/6

we have

$\frac{2}{6}(1)=\$0.33$

3) if Alyssa rolls a 6, she gives Gabriel $12

The probability is 1/6

we have

$-\frac{1}{6}(12)=-\$2$ ---> is negative because is a loss

therefore

Alyssa's expectation is equal to

$\$2+\$0.33-\$2=\$0.33$

Part b) Determine Gabriel's expectation

we know that

1) If Alyssa rolls a 1, 2, or 3, Gabriel gives Alyssa $4

Is a loss for Gabriel

The probability is 3/6

we have

$-\frac{3}{6}(4)=-\$2$ ---> is negative because is a loss

2) If Alyssa rolls a 4, or 5, Gabriel gives Alyssa $1

Is a loss for Gabriel

The probability is 2/6

we have

$-\frac{2}{6}(1)=-\$0.33$ ---> is negative because is a loss

3) if Alyssa rolls a 6, she gives Gabriel $12

Is a win for Gabriel

The probability is 1/6

we have

$\frac{1}{6}(12)=\$2$

therefore

Gabriel's expectation is equal to

$-\$2-\$0.33+\$2=-\$0.33$

The elevation of a sunken ship is -120 feet. Your elevation is 5/8 of the ship's elevation. What is your elevation?

Lorico [155]

The question is basically asking "What is 5/8 times -120?"

Well, 1/8 of -120 is going to be equivalent to -120 ÷ 8.
-120 ÷ 8 = -15.

5/8 of -120 is just going to be 5 eighths.
-15 × 5 = -75 feet

Find the equation (in terms of x) of the line through the points (-2,4) and (2,0) y =

solong [7]

Answer:

y = - x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$
