So, i would use the add the two equation method, so add those to get:
2e=-4
e=-2
then plug in e to get d, so d+-2=1
d=3
plug into the other one to make sure
-3+-2=-5
so it would be (3,-2)
The answer should be 3.5 pounds. You divide 56 by 16 to get your answer
Answer:
ummm im pretty sure its d
Step-by-step explanation:
Answer:
D)The experimental probability is greater than the theoretical probability
Step-by-step explanation:
Given:
75 times a die is rolled out of 39 times it got 6
To Find :
Which statement is true?
Solution:
The theoretical probability is given by the ,
Pt=No.of favorable outcomes/Total outcomes
Here favorable is getting 6 on the die
so how many times we can get 6 =1 time
Total outcomes =6
Pt=1/6
Pt=0.1667
Now for
The experimental Probability ,
Pe=Number times that event occur /Total no of trails
Here 39 times we get 6 and total no trails are 75
Pe=39/75
Pe=0.52
Hence we can say that Pe>Pt.
Here is some thoughts on this:
cos 57 = sin (90-57) = sin 33
so cos 57 . cosec 33 = cos 57 / sin 33 = sin 33 / sin33 = 1
2 cos 60 = 2 * 1/2 = 1
so the last 2 parts work out to 0
now we have to find cos 70 / sin 20
sin 20 = cos 70 so this comes to 1
so finally the answer is 1
