The initial outlay or cost is $1,000,000 for a four-year project. The respective future cash inflows for years 1, 2, 3 and 4 are

trasher [3.6K]

Answer:

The Payback Period from non discounted cash flows is 2 Years and 8 months

Step-by-step explanation:

With an initial outlay of $1,000,000

and Cash inflows for 4 years consecutively of $500,000 + $300,000 + $300,000 + $300,000

Pay back Period = the Period where Initial Outlay minus Cash Inflows equal Zero

= 1,000,000 - 500,000 (yr 1) - 300,000 (yr 2) - 200,000 (2/3 of Year 3) = 0

Pay back Period therefore is equal to 2 years & 8 months.

Just find the vertex and then compare with graph

y=2x²-8
y=2(x-0)²-8

Parabola opening upwards

Vertex at (0,-8)

Graph 3

y=(x+3)²+0

Vertex at (-3,0)

Graph IV

y=-2(x-4)²+8

Parabola opening downwards as a is -ve

Graph I

One graph is left

If Alfie tosses the paper cup more times, what is the expected number of times that the cup will land on its side?

IRINA_888 [86]

Question:

Alfie tossed a paper cup in the air 150 times and recorded the side it landed on.

Right side up = 60 Upside down = 53 Side = 37

If Alfie tosses the paper cup 100 more times what is the expected number of times the cup will land on its side?

Answer:

The expected number of times the cup will land on its side is 25 times

Step-by-step explanation:

Given

$Right = 60$

$Upside\ down = 53$

$Side = 37$

Required

First, we calculate the probability of landing on side

$P(Side) = \frac{n(Side)}{Total}$

$P(Side) = \frac{37}{150}$

$P(Side) = 0.247$

Next, we calculate the expected value; E(x) using:

$E(x) = n * P(x)$

When tossed 100 more times:

n = 100 and P(x) = P(Side) = 0.247

So:

$E(x) = 100 * 0.247$

$E(x) = 24.7$

$E(x) = 25$ --- approximated

<em>Hence, it is expected that it will land on its side 25 times</em>

if a supplement of an angle has a measure 78 less than the measure of the angle, what are the measures of the angles?

Citrus2011 [14]

Answer:

x + x -78= 180

2x - 78= 180

2x = 258

x = 129

x-78= 51
