See image for naming of the sides: the medians are
ab, bc, and ac; and sides are a, b, and c
Pick one median, say, ab. The following are true:
ab < a
ab < b
->
ab + ab < a + b
ab < 0.5*(a+b) | add 0.5*c to the right hand side (does not change inequality)
ab < 0.5(a+b+c) = half perimeter
so ab < half perimeter
Same argument for bc, and ac holds.
Will Smith paid $857.19 for the 60 inch TV.
Step-by-step explanation:
Step 1:
The 60 inch TV sells for $1,250. The electronics store offers a discount of 35%.
So the price that is paid for the TV is reduced by 35%.
We need to determine how much 35% of $1,250 is.
35% of $1,250
So a discount of $437.50 is applied to the original price.
The discounted price
The discounted price of the TV is $812.50.
Step 2:
A sales tax rate of 5.5% is applied where Will Smith lives.
We need to determine how much 5.5% of $812.50 is.
5.5% of $812.50
So a sales tax of $44.6875 is applied to the original price.
The total price
Rounding this off, Will Smith paid $857.19 for the 60 inch TV.
1/10
All you have to do is divide the numerator by the denominator
In this case 1 divided by 10 = 0.1
Hope this helps
Answer:
0.9 = 90%
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula.
Miles per gallon of a vehicle is a random variable with a uniform distribution from 25 to 35.
This means that
The probability that a random vehicle gets between 25 and 34 miles per gallon is:
So the answer is 0.9 = 90%
Answer:
60%
Step-by-step explanation:
A percent is technically just a fraction over 100.
To get that here, we simply divide the part (which is 1560 people) by the whole (which is 2600 people) and then multiply that by 100:
(1560 / 2600) * 100 = 0.6 * 100 = 60/100
Thus, we know that the percent is 60%.
