Answer:
1. 23.8
2. 7.7
Step-by-step explanation:
<u>for the first blank</u>
use sin because x is opposite and 25 is hypotenuse
set up an equation:
sin(72)= (x/25)
multiply both sides by 25:
25(sin(72))= (x/25)25
25(sin(72))= x
multiply 25 by sin(72):
23.8 = x
<u>for the second blank</u>
use cos because x is adjacent and 25 us hypotenuse
set up an equation:
cos(72)= (x/25)
multiply both sides by 25:
25(cos(72))= (x/25)25
25(cos(72))= x
multiply 25 by cos(72):
7.7= x
A graphing calculator can help find the number(s) that meet this requirement.
The number could be 15, or -14.
The formula for the Pythagorean therom is: a[tex] a^{2} + b^{2} = c^{2}
So, If a^{2} and b^{2} add up to c^{2} than it is a Pythagorean triple.
For example, the probability of choosing a male who prefers sports cars is 39/240 or 16%. The probability of choosing a male is 60/180 = 25%.
Two Way Relative Frequency Table. To convert counts into relative frequencies, divide the count by the total number of items. In the above table, the first count is for men / Rom-com (count=6), so 6/60 = 0.1.
