Well, it says that they got heads 28 times by flipping the coin 75 times, so to find the probability, you just do this : 28/75 = 0.373333333.
So, the correct answer is A.
Answer:
im pretty sure its 30%. because 70% are in heath. so 30% of the students arent. i think... hope this helped.
Step-by-step explanation:
Answer:
The slope is -1/8 and the y intercept is 7/6
Step-by-step explanation:
This equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -1/8 x + 7/6
The slope is -1/8 and the y intercept is 7/6
Answer:
px = P(X=1) = 0.05
Step-by-step explanation:
px represent the success probability for X, meaning that it is just the probability that there is a discoloration of the applied glaze on the ceramic surface and for only one sample, the probability that the sample is discoloured is evidently given as 5% = 0.05
px = P(X=1) = 0.05
Answer:
96 yards
Step-by-step explanation:
This is basically just a huge addition problem that we can tackle (heh) in our heads.
If we gain yards, then we add.
If we lose yards, then we subtract.
If we started out at 50, the expression is
.
We can use the associative property of addition to simplify this. I'm just grouping together things that look easy to do in my head.
