Answer:
B. False
Step-by-step explanation:
A moderate positive correlation, e.g. r = 0.5 or 0.6, shows that there is some relationship between driving faster and accidents that result in more severe injuries. But that relationship is not very strong or solid and can result from other variables being involved or simply randomness. You cannot affirm that X causes Y if the correlation is not strong.
Answer:
£33,000
Step-by-step explanation:
The money he gives to his daughter is represented by the 3 in the ratio so you divide £9000 by 3 to get £3000
The money he invests is represented by 11 in the ratio so you multiply £3000 by 11 to get £33,000
Hope this helps! :)
Answer:
The answer is C
Step-by-step explanation:
Answer:
36, 32, 28, 24
Step-by-step explanation:
Fill in the values of n and do the arithmetic.
a1 = 36 -4(1 -1) = 36
a2 = 36 -4(2 -1) = 32
a3 = 36 -4(3 -1) = 28
a4 = 36 -4(4 -1) = 24
_____
You could recognize the formula as the specific case of the explicit formula for an arithmetic sequence with first term 36 and common difference -4. That tells you the second term is 36 -4 = 32, and each successive term is 4 less than the one before.
