Joan incorrectly finds the volume of a cone with a radius of 4 cm and a height of 6 cm. She thinks the volume is 301.44 cm3. Her

work is shown below. Find and correct Joan’s mistake. Then, find the correct volume of the cone. Use 3.14 for π.

Answer:

Correct volume = 100.48 cm³

Step-by-step explanation:

The formula for finding the volume of a cone is:

V = πr²(h/3)

r - Radius

h - Height

V - Volume

To find the correct volume of the cone, we just need to input the measurements into their respective places in the formula and solve. Your work should look similar to the following:

V = πr²(h/3)

V = π(4)²(6/3)

V = π(16)(6/3)

V = π(16)(2)

V = π(32)

V = 100.48 cm³

(You can use the work shown above to find Joan's mistake in her work.)

~Hope this Helps!~

Will do first question of each concept only because the rest of the questions are the same concept (the same few repeat but whatever).

1. <em>Total angle = (n - 2) * 180 --> 4 * 180 = 360°</em>

<em>70 + 130 + 120 + θ = 360</em> --> 320 + θ = 360 --> θ = 40

4. Total angle =<em> (10 - 2) * 180</em> --> 8 * 180 = <em>1440</em>

<em>1440/10</em> = 144°

6. Interior: (n - 2) * 180 --> 10 * 180 = 1800

Exterior: 12 * 180 = 2160 --> 2160 - 1800 = 360

9. (n - 2) * 180 --> 3 * 180 = 540

90 + 90 + 150 + 160 + θ = 540 --> 490 + θ = 540 --> θ = 50

13. Interior: (n - 2) * 180 --> 2 * 180 = 360

Exterior: n * 180 - (n - 2) * 180 --> 180n - 180n + 360 --> 360 (always the same)

16. 7r + 4r + 8r + 5r = 360 --> 24r = 360 --> r = 15

You have torn a tendon and are facing surgery to repair it. the surgeon explains the risks to you: the probability of infection
skad [1K]
P(most favorable outcome) = 1 -(0.03 +0.16 -0.01) = 0.82

_____
"repair fails" includes the "infection and failure" case, as does "infection". By adding the probability of "repair fails" and "infection", we count the "infection and failure" case twice. So, we have to subtract the probability of "infection and failure" from the sum of "repaire fails" and "infection" in order to count each bad outcome only once.

The probability of a good outcome is the complement of the probability of a bad outcome.

s344n2d4d5 [400]

Kevin installed a certain brand of automatic garage door opener that utilizes a transmitter control with four independent​ switches, each one set on or off. The receiver​ (wired to the​ door) must be set with the same pattern as the transmitter. If six neighbors with the same type of opener set their switches​ independently.<u>The probability of at least one pair of neighbors using the same​ settings is 0.65633</u>

Step-by-step explanation:

<u>Step 1</u>

In the question it is given that

Automatic garage door opener utilizes a transmitter control with four independent​ switches

<u>So .the number of Combinations possible with the Transmitters </u>=

2*2*2*2= 16

<u> Step 2</u>

Probability of at least one pair of neighbors using the same settings = 1- Probability of All Neighbors using different settings.

= 1- 16*15*14*13*12*11/(16^6)

<u> Step 3</u>

Probability of at least one pair of neighbors using the same settings=

= 1- 0.343666

<u> Step 4</u>

<u>So the probability of at least </u>one pair of neighbors using the same settings

is  0.65633
