Perimeter of triangle = all sides added up
3a + 4 + 2a - 7 + 9a + 11
now add like terms
3a + 2a + 9a = 5a + 9a = 14a
4 - 7 + 11
= -3 + 11 = 8
so we have 14a + 8
as our simplest expression
The probability of profiting $5.2 million is 5% = 0.05
The probability of profiting $0.9 million is 50% = 0.5
The probability of breaking even, meaning no profit gain, is 45% = 0.45
Expected profit values of the CD is given by
(0.05×5.2) + (0.5×0.9) + (0.45×0) = 0.26+0.45+0 = 0.71 million
<span>Tan(x)=2
Or for x=45 tan(x)=1
then for tan(x)=2 ; x must be superior to 45
Then the answer is </span><span>d. 63.4 degrees</span>
sara speed is half of Jeanette's so if jeanette ran 7 miles then her walking speed is 3.5MPH and sense she is 7 miles ahed sara is 10.5 miles behind... 3.5MPH which is jeanette speed is double than sara so 3.5/2 is 1.75MPH... Saras walking speed is 1.75MPH
Both FI and GJ are diameters.
