Sunny has a six-sided number cube labeled with the numbers 1 through 6 and a spinner, shown below. What is the probability that
Grace [21]

Answer:

P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{24}

Step-by-step explanation:

Given

Cube = \{1,2,3,4,5,6\}

n(Cube) = 6

Spinner = \{A,B,C,D,E,F,G,H\}

n(Spinner) = 8

See attachment for spinner

Required

P(Cube \ge 5\ and\ Spin[A])

On a number cube, we have:

Cube \ge 5 = \{5,6\} ---- i.e. 2 outcomes

So, the probability is:

P(Cube \ge 5) = \frac{n(Cube \ge 5)}{n(Cube)}

P(Cube \ge 5) = \frac{2}{6}

P(Cube \ge 5) = \frac{1}{3}

On the spinner, we have:

Spin [A] = \{A\} ---- i.e. 1 outcomes

So, the probability is:

P(Spin[A]) = \frac{n(Spin[A])}{n(Spinner)}

P(Spin[A]) = \frac{1}{8}

P(Cube \ge 5\ and\ Spin[A]) is calculated as thus:

P(Cube \ge 5\ and\ Spin[A]) = P(Cube \ge 5) * P(Spin[A])

P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{3} * \frac{1}{8}

P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{24}

Determine the scale factor of the function f(x)=1/3root x
Travka [436]
Please be clear with the expressions.
Here we assume 
f(x)=(1/3) sqrt(x)

A scale factor is a multiplier applied to a parent function.
If the parent function is f(x), and
g(x)=a*f(x), then a is a scale factor.

Assuming the parent function is sqrt(x), and f(x)=(1/3) sqrt(x)
then the scale factor is  (1/3).
[note]
if f(x) is a cube root, then write
f(x)=cube root(x), or f(x)=x^(1/3).
the exponentiation sign ^ is very useful.

I’m pretty sure you can first do 10% at a time which you can round to 13 which is 3 so 3 plus 3 then add tax

A garbage container is to be constructed out of 400 ft2 of material. The vessel will have a square base and an open top. Find th
sveticcg [70]

Answer:

  11.547 ft wide by 5.774 ft high

  769.800 ft³ capacity

Step-by-step explanation:

Volume is maximized for a given area by having the area of a pair of opposite sides equal the area of the bottom. That means the overall area of the container is 3 times the area of the bottom. Then the square bottom will have a width of ...

  w = √(400/3) ≈ 11.547 . . . feet

The height is half that, so is ...

  h = w/2 = 11.547/2 ≈ 5.774 . . . feet

The capacity is then ...

  w²h = (11.547 ft)²(5.774 ft) = 769.800 ft³

The container is 11.547 ft wide by 5.774 ft high. It has a capacity of 769.800 cubic feet.

_____

You want to maximize w^2h subject to w^2 + 4wh = 400. Solving the constraint equation for h, we get h = (400 -w^2)/(4w) and the volume we want to maximize can be written as ...

  V = w(400-w^2)/4

This will be an extreme when dV/dw = 0, so we want to solve ...

  dV/dw = 0 = 100 -(3/4)w^2

  w^2 = 400/3

  w = √(400/3) . . . . . as above
