Answer:
a.) .95
b.) The expected number of baskets is 10.50.
c.) 1.7748
Step-by-step explanation:
a.) This is a binomial distribution as there are two possibilities: makes a free throw or doesn't. This means that you can use the binomial function on a calculator to figure out the answer. Use the binomial CDF function on a calculator and the number of trials=15, probability of success=.7, lower bound=0, upper bound=7. Once you have evaluated the answer, .0500, it will need to be subtracted from1, as you want everything not included in this section. The answer to part a is thus 1-.0500=.95.
b.) The expected value is calculated by taking the total number of shots and multiplying it by the probability of making the shot: 15×.7=10.5 shots.
c.) The standard deviation of a binomial distribution can be calculated by the formula  . Plugging in the numbers you get
. Plugging in the numbers you get  =1.7748.
=1.7748.
 
        
             
        
        
        
Answer:
Center: the middle of the circle. Radius: the fixed distance from the center to any point on the circle is called the radius.
Step-by-step explanation:
The center is a fixed point in the middle of the circle; usually given the general coordinates (h, k). The fixed distance from the center to any point on the circle is called the radius.
 
        
             
        
        
        
Answer:
Can't be determined. 
Step-by-step explanation:
From the fact that the quadrilaterals are similar: 
Corresponding sides are in proportion and
Corresponding angles are congruent. 
We can't create a proportion, so there's nothing else that we can determine.
 
        
                    
             
        
        
        
Even numbers on die: 2,4,6
odd numbers on die: 1,3,5 
3+3=6 -> 6 numbers in total
3/6 chance because there are 3 even numbers. This would round to 1/2, so 1/2 a chance the die will roll an even number.
