Answer:

37.68 units³

Step-by-step explanation:

To calculate the volume of a cone, the formula is:

V = π x r² x ( h / 3 )

Simply input the corresponding numbers into the equation:

V = π x ( 2 )² x ( 9 / 3 )

V = π x 4 x ( 3 )

V = π x 12

V = 3.14 x 12

V = 37.68 units³

If we use 3.14 for pi, the answer comes out to 37.68 units³

In an agricultural study, the average amount of corn yield is normally distributed with a mean of 185.2 bushels of corn per acre

RideAnS [48]

Answer: B. 461 acres

Step-by-step explanation:

Given : In an agricultural study, the average amount of corn yield is normally distributed with a mean of 185.2 bushels of corn per acre, with a standard deviation of 23.5 bushels of corn.

i.e. $\mu=185.2\ \ , \ \sigma=23.5$

Let x denotes the amount of corn yield.

Now, the probability that the amount of corn yield is more than 190 bushels of corn per acre.

$P(x>190)=P(\dfrac{x-\mu}{\sigma}>\dfrac{190-185.2}{23.5})$

[Formula : $z=\dfrac{x-\mu}{\sigma}$ ]

$=P(z>0.2043)=1-P(z$ [∵ P(Z>z)=1-P(Z<z)]

$1-0.5809405$ [using z-value calculator or table]

$=0.4190595$

Now, If a study included 1100 acres then the expected number to yield more than 190 bushels of corn per acre :-

$0.4190595\times1100=460.96545\approx461\text{ acres}$

hence, the correct answer is B. 461 acres .

70. Write the standard form of the equation of the line with

nasty-shy [4]

Answer:

y = -2x - 8

Step-by-step explanation:

<u>Use the point slope form: (y - y1) = m(x - x1)</u>

(y - (-4)) = -2(x - (-2))

y + 4 = -2(x + 2)

y + 4 - 4 = -2x - 4 - 4

y = -2x - 8

Answer: y = -2x - 8
