Your rows would be $0.90 Chocolate, $1.20 Chocolate, and the Total Chocolate Mix, and your columns would be the Amount of Chocolate in #s and the Total Costs
(This is the best I can do coming up with a grid)
________________amt (#)_________total costs
$0.90_____________10______________9.00
$1.20______________x______________1.20x
Total Mix_________10+x_____________9+1.2x
Using this grid, you see that 10+x=9+1.2x so solve for x
10+x -x=9+1.2x -x
10=9+.2x
10 -9=9+.2x -9
1=.2x
1/.2=(.2x)/.2
x=5, so you need 5lbs of the $1.20 chocolate to produce a mixture worth $1.00
The probability that none of them will be returned is 0.729.
Probability:
Probability refer the possibility of the required event.
The probability of an event is a number between 0 and 1, where 0 indicates impossibility of the event and 1 indicates certainty.
Given,
Aram's fine gems allows a customer to return a diamond tennis bracelet if the return occurs within ten days.
Return percentage of the Bracelet = 10%
And, three (3) tennis bracelets are bought by three (3) different customers.
Now, we need to find the probability that none of them will be returned.
Let R be the event of bracelets sold that are returned.
And R' be the event of bracelet sold but not to be returned.
So,
P(R) = 10%
=> P(R) = 0.10
P(R') = (1 - P(R))
=> P(R') = (1 - 0.10)
=> P(R') = 0.90
Now we need to find the probability that none of them are retuned for 3 customers.
Which is equal to
=> 0.90 x 0.90 x 0.09
=> 0.729

A blueprint of a house has a scale of 1 in: 6 ft. If a bedroom has a width
of 2 in on the blueprint, what is the actual width of the bedroom?
So 1 inch on the blue print = 6 feet irl (in real life)
So 2 inch on the blue print = 6*2 = 12 feet irl
So the actual width of the bedroom is 12 feet.
