Problem Page Donna had 2/7 acres of land. She planted 4/5 of it with corn. How many acres did she plant with corn?

Dafna11 [192]

Acres of planted corn = (2/7) * (4/5)

= (2/7) * .8 = 1.6 / 7 acres = 0.2285714286 acres

AnnyKZ [126]

Answer:

a) In the interval ( 55,9 ; 456,7 ) we will find 99,7 % of all values

b) In the interval ( 122,7 ; 389,9 ) we find 95,4 % of all values

Step-by-step explanation:

For a Normal distribution N (μ ; σ ) the Empirical rule establishes that the intervals:

( μ ± σ ) contains 68,3 % of all values

( μ ± 2σ ) contains 95,4 % of all values

( μ ± 3σ ) contains 99,7 % of all values

If N ( 256,3 ; 66,8 )

σ = 66,8 ⇒ 3*σ = 3 * 66,8 = 200,4

Then: 256,3 - 200,4 = 55,9

And 256,3 + 200,4 = 456,7

a) In the interval ( 55,9 ; 456,7 ) we will find 99,7 % of all values

b) 2*σ = 2 * 66,8 = 133,6

Then 256,3 - 133,6 = 122,7

And 256,3 + 133,6 = 389,90

Then in the interval ( 122,7 ; 389,9 ) we find 95,4 % of all values

4. Here are the equations that define three functions.

luda_lava [24]

The functions f(x), g(x) and h(x) are all linear functions

The function value that is largest is h(-100)
The function value that is largest is h(-100)
The function value that is largest is f(1/100)

<h3>How to determine the function with the largest values</h3>

The functions are given as:

$f(x) = 4x - 5$

$g(x) = 4(x - 5)$

$h(x) = x/4 -5$

At x = 100, we have:

$f(100) = 4 * 100 - 5 = 395$

$g(100) = 4 * (100 - 5) = 380$

$h(100) = 100/4 - 5 = 20$

Hence, the function value that is largest is f(100)

At x = -100, we have:

$f(-100) = -4 * 100 - 5 = -405$

$g(-100) = 4 * (-100 - 5) = -420$

$h(-100) = -100/4 - 5 = -30$

Hence, the function value that is largest is h(-100)

At x = 1/100, we have:

$f(1/100) = 4/100 - 5 = -4.96$

$g(1/100) = 4 * (1/100 - 5) = -19.96$

$h(1/100) = (1/100)/4 - 5 = -4.9975$

Hence, the function value that is largest is f(1/100)
