Letters a, b, c, and d are angles measures.
1 answer:
The answers are:
a = c
c = d
b + d =180 degrees
Here's how:
When a line intersects two parallel lines, then corresponding angles are formed which means the same corners are congruent.
option c = d is considered.
And, because of vertical angles,
a = d is also an answer.

Answer:
Step-by-step explanation:
We know that the mean and standard deviation of the sampling distribution of the sample proportion() is given by :-
, where p= Population proportion and n = sample size.
Let p be the proportion of blue chips.
As per given , we have
p= 0.275
n= 5
Now , the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 will be :
Hence, the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 are :
