Step-by-step explanation:
14/5-6 HE DIDNT TOOK LCM AND CUT 5 WITH THE ANOTHER 5 WHICH IS OUTSIDE
Answer:
$7.80
Step-by-step explanation:
Multiply 0.4 (that is 40%) by 13
It would be 5.2
So subtract 5.2 from $13.00
7.8
So the CD price would be $7.80 with a 40% discount
Hope this helps you :)
If you mean like a method to solve it fast here I have 1 solution I usually use;
3x2.7
3x.7=2.1
3x2=6
Then in the question there is 1 number behind the decimal point so the answer should have 1 number behind as well.
=8.1
The answer is 80 hope this helps :)
Answer:
a) State the random variable
Random variable : x
which refers to a randomly selected student from the college that is left-handed.
b) state population parameter
population parameter : P
which is the percentage of all students from the college that are left handed
c) state the hypotheses
The hypothesis are;
Null hypothesis H₀ : p = 0.11
Alternative hypothesis H₁ : p > 0.11
d) State the Type I error in the context of this problem.
Type - I Error: Rejecting that the % of all the students from the college that are left-handed is 11% when actually the % is really 11%
(Reject H₀ when H₀ is true)
e) State the Type 11 error in the context of this problem
Type-II Error: Failing to Reject that the % of all the students from the college that are left-handed is 11% when the % is really higher than that
(Fail to reject H₀ when H₀ is false)
