Answer:
so what i have to do
Step-by-step explanation:
Answer:
A. 
Step-by-step explanation:
We are given the expression, 
On re-writing the expression after borrowing 1, we have,
=
i.e.
= 
i.e.
= 
Thus, the equivalent expression after borrowing 1 from the given expression is
.
Hence, option A is correct.
Answer: I believe those would be opposite angles (aka vertically opposite angles).
Answer:
The p -value is less than 0.001.
Step-by-step explanation:
Given information:
Sample size = 25 chips
Sample mean = 985
Sample standard deviation = 10
Let as assume that sample is distributed normally.
The formula for test statistic

where,
is sample mean
μ is population mean.
s is sample standard deviation.
n is sample size.
The value of test statistic is



The p-value is

Therefore the p -value is less than 0.001.
Supplementary angles are two angles whose measures sum to a 180 degrees and complementary are the sum have to add up to 90 degrees.So 180÷2=90;90÷2=45;180÷6=30 and 90÷6=15.Altough the answer is A.
