Answer:

y=-x-4

Step-by-step explanation:

You can write the equations in point-slope form first.

1) y+3=-(x+1)

2) Then you can convert it into slope intercept form

3) y=-x-1-3

4) y=-x-4

You are playing a board game with a friend. She owns and has developed the tiles Green Gardens and Silver Sidewalks. If you roll

IgorC [24]

Answer:

The expected value can be calculated as:

Es = x₁*p₁ + x₂*p2 + .....

where xₙ is the event (the amount of money that you win or lose, and pₙ is the probability for the event)

for example, in a 10 side dice, the probability of obtaining a specific number is 1/10.

we have a d10 i guess (a dice with 10 sides, 1 to 10)

if you roll from 1 to 7, nothing happens.

If you roll an 8, you lose $1500

if you roll a 9, you lose $75

if you roll a 10, you lose $2000 (and the game)

the expected value is,

Es = 1/10*(7*0 - 1*$1500 - 1*$75 - 1*$2000) = -$357

in the second case, you start paying $500.

if you roll a 7, you must pay $1000, if else, nothing happens.

Then the expected value is

Es = -$500 - 1/10*(-1*$1000 + 9*$0) = -$600

So the expected value is smaller in this case, so the deal is not fair

Ling has $6 to buy 42-cent postage stamps. What is the greatest number of stamps that she can buy?*

Kazeer [188]

Answer:

14 stamps

Step-by-step explanation:

She has 6.00 dollars in total so you would divide 2.00 by 0.42 to get 14.286, but you can't but .286 of a stamp so the answer is 14

Answer:

$0.00851=8.51\times 10^{-3}$ cm.

Step-by-step explanation:

We have been given that the average human body cell is about $5.1\times10^{-4}$ cm in diameter. The diameter of a plant cell is $8\times10^{-3}$ cm.

To find the combined diameter of the body cell and plant cell, we will add both diameters.

First of all let us convert our given diameters in standard notation.

$5.1\times10^{-4}=0.00051$

$8\times10^{-3}=0.008$

$\text{The combined diameter of body cell and plant cell}=0.00051+0.008$

$\text{The combined diameter of body cell and plant cell}=0.00851$

Let us convert our answer in scientific notation.

$\text{The combined diameter of body cell and plant cell}=8.51\times 10^{-3}$

Therefore, the combined diameter of the body cell and plant cell is $0.00851=8.51\times 10^{-3}$ cm.
