Answer:
B
Step-by-step explanation:
Use the formula for radius and circle circumference.
Since we know the diameter, if we divide that by 2, we can get the radius.
Now we can plug that value into the circumference formula to get the circumference.
*Since we're rounding to the nearest inch.
Answer:
n = 20 q = 0.7, q = 0.3
Step-by-step explanation:
For each shot that she takes, there are only two possible outcomes. Either she makes or, she does not make is. The probability of making each shot is independent from other shots. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
We also ahve that q = 1-p.
Jackie is practicing free throws after basketball practice. She makes a free throw shot with probability 0.7.
This means that and
She takes 20 shots.
This means that
So the correct answer is:
n = 20 q = 0.7, q = 0.3
Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 = ( multiply both sides by 3 )
24 = k
y = ← equation of variation
