Answer:
B) 
Step-by-step explanation:
∠4 and ∠2 are vertical angles as well, but since they are already used, all that are left to use are ∠3 and ∠1, which are the other vertical angles.
I am joyous to assist you anytime.
Answer:
Standard deviation, means, skewness and kurtosis.
Step-by-step explanation:
Two normal curves may be same but they have different means, standard deviation and skewness. There can be different standard deviation for two curves and there is difference in skewness.
Answer:
-3
Step-by-step explanation:
because of the root
Number: 1111
1111/1111=1
1*0= 0
Now put 0 in the tenths place
01
Hope this Helped :)

now.. 0.3 is just a value...we'e assuming Radians for the inverse cosine, so, if you check, make sure your calculator is in Radian mode
