1.theoretical is not counting the results of the experimentssince there are an equal number of red and black and red, the probblity (theoretical) of picking a black one is 1/3
experimental=number of outcomes happened/total number of tests4 times black, 4 tests, so 4/4 or 100%=experimental proablity
2. experimental considered previous trials and theoretical did not
3. theoretical=(1/4) the trials don't influence each other so1/(4*4)=1/16
A) constant=40, coefficient=7.50, variable=h
B)7.50h+.20s+40
7.50(25)+.20(300)+40
187.5+60+40=287.5$
C)9.0h+.2s+40, So yes a coefficient would change, but nothing else
Answer:
Step-by-step explanation:
Using the exact values of the given trig functions, then
sin45° × sin30° × cos60°
= 
× 
× =
cos (90° - x) should be the answer
