Answer:
I don't know how to do this thing
Answer:
144
Step-by-step explanation:
(81 - 9) * 2 = 144
work backwards, you now have 81 books. But you bought 9, so pretend you didn't buy the 9, means you would have 9 less books. so 81-9.
Then you multiply by 2 because originally you sold half of the books, so before you sold half, you had double the amount, so you multiply that by 2.
Answer:
There is sufficient evidence to support the claim that the standard deviation of time all women spend washing their hair in the morning is 15 seconds
Step-by-step explanation:
We shall need to formulate the hypotheses but first we need to understand the claim in context of this question. The claim is that the standard deviation of time all women spend washing their hair in the morning is 15 seconds. In mathematical notation, this claim can be written as follows;
σ = 15
Clearly the claim contains an equality sign and thus it qualifies to be our null hypothesis;
H0: σ = 15
The complement of the above hypothesis will be our alternative hypothesis;
Ha: σ ≠ 15
We are then informed that the initial conclusion of the test fails to reject the null hypothesis. In short this implies that we fail to reject the claim that the standard deviation of time all women spend washing their hair in the morning is 15 seconds since this claim is our null hypothesis. If we fail to reject a claim in hypothesis testing, this implies that there is sufficient evidence to support the claim. Therefore, there is sufficient evidence to support the claim that the standard deviation of time all women spend washing their hair in the morning is 15 seconds
Answer:
as an instinct i thought that i should multiply 11 and 5, so im saying 55 different selections
Step-by-step explanation:
sorry if im wrong
1) f(1) = 0 ; f(2) = 1 ; f(n) = f(n-1) + f(n-2) , for n > 2
f(3) = f(3-1) + f(3-2) = f(2) + f(1) = 1 + 0 = 1
f(4) = f(4-1) + (4-2) = f(3) + f(2) = 1 + 1 = 2
f(5) = f(5-1) + (5-2) + f(4) + f(3) = 2 + 1 = 3
1st five terms of the sequence are 0, 1, 1, 2, 3
2) There is no graph. This question can't be answered.
