Sarah has 273 feet of wire to make bead necklaces. If each necklace requires 1 2/3 feet of wire, how many necklaces can she make
o-na [289]

Oh boy, here we go again

First we must convert  1 2/3 to an improper fraction.  By doing this, we get 5/3  (3/3 + 2/3)

So now we have 273 /  5/3

To divide this easier we can do something that when I learned it was called (keep, change, flip)  which basically means keep the first fraction, change the sign from division to multiplication, and flip the second fraction

This now turns into:  273/1 * 3/5

Combine 273 and 3/5

273⋅3/5

Multiply 273

by 3

819/5

is your answer

Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four e
Alexxx [7]

Answer:

0.25

Step-by-step explanation:

This is the question on conditional probability

Let A - the quadrilateral has four right angles

B - the quadrilateral has four equal side lengths

Required probability = P(B/A)

By definition of continuous probability

P(B/A) = \frac{P(AB)}{P(A)}

P(AB) = \frac{2}{20} =0.10

P(A) = \frac{8}{20} =0.4

Hence given probability = \frac{0.1}{0.4} =0.25

F(x) = 3x² + 6x - 1

The graph is a parabola open upward (a= 3>0) with a minimum.

Calculate the vertex:

x = -b/2a → x = -6/(2.3) = -1. Then the axis of symmetry is x = - 1
Now to calculate the minimum, plugin the value of x:

y = 3x² + 6x - 1

y = 3(-1)² + 6(-1) -1

y= 3 - 6 -1 and y = - 4,

Ten the vertex (minimum) is at (-1,- 4)
