Step-by-step explanation:
The two like fractions can be set as x and y (just to use two variables).
One of them is 
, though, so we can set one of the variables equal to that value (I'm just going to make 
, it doesn't matter which variable you use).
We also know that adding the two variables gives us 
so now we can make an equation.
Answer:
Answer:
is greater than
Step-by-step explanation:
Mean: sum of numbers ÷ how many numbers there are
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.83333
Median: middle number
<u>3</u> <u>3</u> 4 5 <u>5</u> <u>9</u>
4 + 5 = 9
9 ÷ 2 = 4.5
4.83333 > 4.5 so the mean is greater than the median.
Hope that helps. :)
Answer:
Option C. cos70°
Step-by-step explanation:
we know that
If two angles are complementary, then the sine of one angle is equal to the cosine of the other angle and the cosine of one angle is equal to the sine of the other angle
Remember that
Tow angles are complementary , if the sum of their angles is equal to 90 degrees
so
If A+B=90°
then
sin(A)=cos(B)
cos(A)=sin(B)
In this problem we have
A=20°
B=90°-20°=70°
therefore
sin(20°)=cos(70°)
cos(20°)=sin(70°)
