Answer:

Volume of cone =  234.45 cm³

Step-by-step explanation:

Given:

Diameter = 8 cm

Radius r = 8 / 2 = 4 cm

Height h = 14 cm

Find:

Volume of cone

Computation:

Volume of cone = (1/3)πr²h

Volume of cone = (1/3)(3.14)(4)²(14)

Volume of cone =  234.45 cm³

Cathy rolls a number cube that is labeled from 1 to 6.
MatroZZZ [7]

Answer: 2/3

Cathy rolls a number cube that is labeled from 1 to 6.

Total outcomes = {1,2,3,4,5,6}

she rolls an even number or a multiple of 3

Outcomes of an even number = {2,4,6}

Outcomes of multiple of 3 = {3,6}

so favorable outcomes of even number or a multiple of 3 = {2,3,4,6}

Probability ( any event) =number of favorable outcomes divide by total  number of outcomes

probability(even number or a multiple of 3) = \frac{4}{6}=\frac{2}{3}

A group of people were given a personality test to determine if they were Type A or Type B. The results are shown in the table b
klemol [59]

The option third "P(Male or Type B) < P(Male | Type B)" is correct because 0.575 < 0.76

<h3>What is probability?</h3>

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

P(Male or Type B) = (number of male + number of type B - number that are both)/total population

\rm = \dfrac{103 + 50- 38}{200 }

= 0.575

P(Male | Type B) = (number of male people inside the type B)/(number of Type B people)

= 38/(38 + 12)

= 0.76

0.575 < 0.76

P(Male or Type B) < P(Male | Type B)

Thus, the option third "P(Male or Type B) < P(Male | Type B)" is correct because 0.575 < 0.76

Find the length of the missing
Ivahew [28]

Answer:

12

Step-by-step explanation:

using pythagoras theorem

here 15 is hypotenuse since it is opposite 0f 90 degree

9 and x are the other smaller sides of a triangle

according to pythagoras thorem the sum of square of two smaller sides of a triangle is equal to the square of hypotenuse. So,

9^2 + x^2 = 15^2

81 + x^2 = 225

x^2 = 225 - 81

x^2 = 144

x = \sqrt{144

x = 12
