The value do you mean absolute value if you do it would be 4
The more observations you make the closer and closer the experimental probability will approach the theoretical probability. In this case the theoretical probability is:
P(HH)=(1/2)(1/2)=1/4
So in 105 trials one would expect to get two heads:
105(1/4)=26.25 times.
Answer:
A -7 - (4)
Step-by-step explanation:
Answer:
a. Tim has completed a greater amount of work.
b. Together they have completed
part of two projects.
Step-by-step explanation:
Let us assume that the project on which Jaime and Tim are working has x amount of space.
Now, given that Jaime has 5 over 11 space of a project completed while Tim has finished 7 over 13 space of the same project.
Therefore, Jaime has completed
amount of space and Tim has finished
amount of space.
a. Now, (7x) \times 11 > (5x) \times 13
⇒
Therefore, Tim has completed the greater amount of work. (Answer)
b. Together they have completed
amount of space out of 2x amount of space. (Answer)
Answer:
y=-2/7x+1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-5-(-1))/(21-7)
m=(-5+1)/14
m=-4/14
simplify
m=-2/7
y-y1=m(x-x1)
y-(-1)=-2/7(x-7)
y+1=-2/7(x-7)
y=-2/7x+2-1
y=-2/7x+1
