Answer: A and D are the correct statements.
1. In ΔBRS and ΔBDC
∠R=∠D and ∠S=∠C [∵ corresponding angles]
So by AA similarity criteria ,
△BCD is similar to △BSR.
2. As RS is parallel to DS then by basic proportionality theorem,
⇒ B is not true.
3. As we can see BC is greater than BS ,so it cannot possible.
If and
where BS=6 then .
4. As RS is parallel to DS then by basic proportionality theorem,
⇒BR×SC=RD×BS.
5. From 4 its not true that BR/RS = BS/SC.
Combine like terms.
2x + 6 + 6x - 1
8x + 5
Answer:
A)
B) Mean = 1.816
Step-by-step explanation:
We are given the following information:
We treat Stephen Curry making any given free throw as a success.
P(Stephen Curry makes any given free throw) = 0.908
Since the probability for the free throw is equal for each trial and free throws are independent.
Then the number of free shots follows a binomial distribution.
A) Probability distribution
where n is the total number of observations, x is the number of success, p is the probability of success.
Here n = 2, p = 0.908
Now x can take values 0, 1 , 2
Putting values, we get,
B) Mean of X
Thus, the mean number of free shots made by Stephen Curry is 1.816
Answer:
x = 64
Step-by-step explanation:
For the lines to be parallel, then
x - 1 = 63 ( corresponding angles )
Add 1 to both sides
x = 64
