Answer:

7.2^2 = 51.84

51.84 x 3.14 = 162.7776(area of circle on bottom)

162.7776 x 17(height) = 2767.2192

2767.2192 divided by 3( x 1/3) = 922.4064

922.4064 rounded to the nearest hundredths place:

922.41 m3

Step-by-step explanation:

Formula of a cone:

base(area) x height x 1/3 (basically just dividing by 3)

The attendance at baseball games at a certain stadium is normally distributed, with a mean of 30,000 and a standard deviation of

lakkis [162]

Answer:

a) 0.964

b) 0.500

c) 0.885

d) $x \geq 32467.5$

e) 0.997

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 30000

Standard Deviation, σ = 1500

We are given that the distribution of attendance at stadium is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

a) P(attendance is greater than 27,300)

P(x > 27300)

$P( x > 27300) = P( z > \displaystyle\frac{27300 - 30000}{1500}) = P(z > -1.8)$

$= 1 - P(z \leq -1.8)$

Calculation the value from standard normal z table, we have,

$P(x > 27300) = 1 - 0.036 = 0.964 = 96.4\%$

b) P(attendance greater than or equal to 30000)

$P(x > 30000) = P(z > \displaystyle\frac{30000-30000}{1500}) = P(z \geq 0)\\\\P( z \geq 0) = 1 - P(z \leq 0)$

Calculating the value from the standard normal table we have,

$1 - 0.500 = 0.500 = 50\%$

c) P(attendance between 27000 and 32000)

$P(27000 \leq x \leq 32000) = P(\displaystyle\frac{27000 - 30000}{1500} \leq z \leq \displaystyle\frac{32000-30000}{1500}) = P(-2 \leq z \leq 1.33)\\\\= P(z \leq 1.33) - P(z < -2)\\= 0.908 - 0.023 = 0.885 = 88.5\%$

$P(27000 \leq x \leq 32000) = 88.5\%$

e) P(attendance less than 33000)

P(x < 33000)

$P( x < 33000) = P( z < \displaystyle\frac{33000 - 30000}{1500}) = P(z < 2)$

Calculating the value from the standard normal table we have,

P(x < 33000) = 0.997 = 99.7%

d) We have to find x such that:

$P( X > x) = P( z > \displaystyle\frac{x - 30000}{1500}) = 0.95$

Calculating the value from the standard normal table we have,

P(z = 1.645) = 0.95

Thus,

$\displaystyle\frac{x - 30000}{1500} \geq 1.645\\\\x \geq 32467.5$

The attendance should be greater than or equal to 32467.5 to be in the top 5% of all games.

Sistemas por el método de reducción por suma o resta.<br> (3x+y=4) y (2x-4y=5)

Cloud [144]

The solution to the system of equation is (3/2, -1/2)

<h3>System of equations</h3>

Given the following system of equations as shown;

(3x+y=4 .... * 4

2x-4y=5 ..... * 1

_______________

12x+4y=16

2x-4y=5

Add both equations

12x+2x = 16 + 5

14x = 21

x = 3/2

Substitute x = 3/2 into any of the equation to have;

2x-4y=5

2(3/2) - 4y = 5

3 - 4y = 5

-4y = 5 - 3

-4y = 2

y = -1/2

Hence the solution to the system of equation is (3/2, -1/2)
