Answer:

Given that $\int\limits^a_b {\frac{1}{2\pi } e^{-1/2} x} \, dx$ is not the easiest equation to solve, and that

the values at the convenient ± 1 sigma,± 2 sigma,± 3 sigma are irrational

using the "rule-of-thumb" "empirical rule" is typically "close enough"

given that the whole probability analysis by definition has some uncertainty in it

Step-by-step explanation:

Erica is making feathered caps for her school play. Each cap must have 3 feathers. Write an equation that represents the number

FrozenT [24]

Answer:

$f=3c$

Step-by-step explanation:

Given:

Number of feathers = $f$

Number of caps = $c$

Number of feathers in each cap = 3

Now, solving by setting up a proportion.

1 cap has 3 feathers. 'c' caps has 'f' feathers.

This gives,

$\dfrac{1}{3}=\dfrac{c}{f}$

Solving by cross multiplication, we get:

$1\times f=3\times c\\\\f=3c$

Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:

$f=3c$

What is the value of -3⁶ +(-4+7)(2)?<br>

svp [43]

-3^6 = -729

-729 +(-4+7)(2)

-729 +(3)(2)

-729 + 6

-723

<em>hope it helps :)</em>

(ps: the result of -3^6 is not +729, the expression that would give this result is (-3)^6
