10-x+y÷2
10-(5)+(2)÷2
10-5+2÷2
7÷2
3.5???
I'm pretty sure that's correct, I'm sorry if it's wrong though
Answer:
B. 0
Step-by-step explanation:
2-2/5-2= 0/3= 0
Another way to look at this is that because they have the same y coordinate, it must simply be a horizontal line, which has a slope of 0
Answer:
B
Step-by-step explanation:
You have side EC=EA (S)
Angle ECD=BAE. (A)
AB=CD. (S)
Answer:
C.
normal distribution
Step-by-step explanation:
The Sampling Distribution of the Sample Proportion. If repeated random samples of a given size n are taken from a population of values for a categorical variable, where the proportion in the category of interest is p, then the mean of all sample proportions (p-hat) is the population proportion (p)
Sample proportion would be normal with mean = p and variance = pq/n where q = 1-p and n= the sample size
The condition is that both np and nq must be greater than 10
Hence we can take that this will be normal provided np>10 or p>1/4 and q >1/4
i.e. p lies between 1/4 and 3/4
C.
normal distribution (assuming conditions are satisfied)
