Part A: the composite shape is composed of a cone and a half sphere

Part B: The volume of the cone is 1186.92 And the volume of the half sphere is 1526.04

Part C: The volume of the composite shape is the solution of                                                          1186.92+1526.04 = 2712.96

The radius of both the cone and the half sphere is 9 inches and the hight of the cone is 14 inches, using the formula (volume = (1/3) · π · r2 · h) Putting the radius in the r spot and squareing it which is equal to 9x9=82 and putting the hight in the h and turning the pi symbol into 3.14 we get

Volume = (1/3) · 3.14 · 82 · 14

We get the volume of the cone which is 1186.92

Then we use the formula (volume = (4/3) · π · r3) putting the radius in where the r is which is equal to 9x9x9 And changing the pi symbol for 3.14 we get

volume = (4/3) · 3.14 · 729 ÷ 2) = 1526.04

We get the volume of the half sphere which is 1526.04

We then add all of it up to get 1186.92 + 1526.04 = 2712.96


I halved it because it's a half sphere

Step-by-step explanation:

Once the rock is on the ground it has no height (h=0)    

h = -16t² + 320

0 = -16t² + 320

16t² = 320

t² = 20

t² = 20

t = √20

t= √4x5

Total number of employee working for four hours per shift for the manager is 2 people.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.

The probability of failure of an event is equal to the difference of the 1 to the success of the event.

Here, the manager records the number of hours, X, each employee works on his or her shift and develops the probability distribution below.

Probability Distribution

Hours Worked: X     Probability: P(X)

           3                         0.1

           4                           ?

           5                        0.14

           6                         0.3

           7                        0.36

           8                       0.06

As, the probability of an event can not be more than the number 1. Thus, the sum of all the probabilities will be equal to 1.

Let suppose the probability of people working for four hour is x. Therefore,

[tex]0.1+x+0.14+0.3+0.36+0.06=1\\x+0.96=1\\x=1-0.96\\x=0.04[/tex]

Now, the total number of people work for the manager is 50. Therefore, total number of people working for 4 hours are,

[tex]0.04\times50=2[/tex]

Hence, total number of employee working for four hours per shift for the manager is 2 people.

Step-by-step explanation:

the area of a circle is

A = pi × r²

the circumference of a circle is

C = 2 × pi × r

so,

A = pi × r² = 64 in²

r² = 64 / pi

r = sqrt(64 / pi) = 8×sqrt(1/pi) in

the circumference is then

C = 2 × pi × r = 2 × pi × 8×sqrt(1/pi) = 16×pi×sqrt(1/pi) =

Answer:

68%

Step-by-step explanation:

The Empirical Rule states that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. Under this rule, 68% of the data falls within one standard deviation, 95% percent within two standard deviations, and 99.7% within three standard deviations from the mean.

The unsorted stem-and-leaf diagram would look like this:

5 | 6, 3, 5, 0, 2

3 | 2, 7, 3, 3, 4

2 | 6, 9, 1, 1

1 | 7, 1, 1, 6, 8

4 | 4, 2, 4, 3, 4

Basically, you separate the given set of numbers by their whole number part (the digit before the decimal) and list the numbers' fractional part (digit after the decimal) in the order you see them.

The sorted diagram would then be

1 | 1, 1, 6, 7, 8

2 | 1, 1, 6, 9

3 | 2, 3, 3, 4, 7

4 | 2, 3, 4, 4, 4

Answer:

The exponential grows at approximately half the rate of the quadratic.

Step-by-step explanation:

Average rate of change of function f(x) over the interval a ≤ x ≤ b :

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

Interval: [tex]0\leq x\leq 1[/tex]

[tex]\implies a=0, b=1[/tex]

Quadratic function:  [tex]f(x)=2x^2[/tex]

[tex]\implies f(0)=2(0)^2=0[/tex]

[tex]\implies f(1)=2(1)^2=2[/tex]

[tex]\implies \textsf{Average rate of change}=\dfrac{f(1)-f(0)}{1-0}=\dfrac{2-0}{1}=2[/tex]

Exponential function:  [tex]f(x)=2^x[/tex]

[tex]\implies f(0)=2^0=1[/tex]

[tex]\implies f(1)=2^1=2[/tex]

[tex]\implies \textsf{Average rate of change}=\dfrac{f(1)-f(0)}{1-0}=\dfrac{2-1}{1}=1[/tex]

Therefore, the exponential grows at approximately half the rate of the quadratic in the interval [tex]0\leq x\leq 1[/tex]

The speed of the first bus is 60 km/h while the speed of the second bus is 80 km/h.

Speed is the rate of change of distance with time. It is given by:

Speed = distance / time

Let a represent the speed of the first bus, and b represent the speed of the second bus.

b = a + 20

At 12:00, t = 3 hours, hence:

a = d/3

d = 3a

Also:

b = d/2.25

d = 2.25b

3a = 2.25b

3a = 2.25(a + 20)

a = 60

b = 60 + 20 = 80

The speed of the first bus is 60 km/h while the speed of the second bus is 80 km/h.

Answer:

My pool's maximum depth: 6ft

My pool's full width: 10ft

My pool's full length: 12ft

(yea, it's pretty big!)

How do I find the area of my pool now?

First, let's start with the distance covered by the pool (area)

We can find that by just doing 10x12, which is 120

So, my pool's distance is 120ft²

EXTRA:

Now, the VOLUME of my pool...

we can find it by doing 6x10x12

6x10=60

6x12=72

60x12=720

So, my pool's VOLUME is 720ft.²

Using the Central Limit Theorem, it is found that since the sample size is greater than 30, a normal approximation can be used, hence the test can be made.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.

In this problem, the distribution of lengths is skewed, however, since the sample size is of 100 greater than 30, a normal approximation can be used, hence the test can be made.
