Answer:
A) rate of change would be dividing the number of songs wanted (150) by the number of weeks downloading (5)
150/5 = 30
since the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -30
Initial value is 150, which is the total number of songs they want
B) rate of change would be dividing the number of songs wanted (150) by the number of weeks downloading (5)
150/5 = 30
since the total quantity wanted is becoming less every week the rate of change would be negative so it becomes -30
Initial value is 150, which is the total number of songs they want
The last pair.
Because 2*4/3*4=8/12
Answer:
A. False
B. True
C. True
D.True
Step-by-step explanation:
A. False . The significance level or alpha is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. 0.01 alpha is better than 0.05 alpha . 0.01 indicate a 1% risk of rejecting the null hypothesis when it is true .
B. True . If the p-value is less than alpha, we reject the null hypothesis . Therefore statistically significant.
C . True . If the p-value is less than alpha, we reject the null hypothesis
D. True . Alpha will be greater than p-value . Therefore we will reject .
Step-by-step explanation:
We just have to remember the line equation <u>y=mx+b</u>
, then place the given equation into this form (y= -3x-6).
Remember that (m) is your slope. So, to find a parallel line, they must have an equal slope. Check the other equations and see which one had a slope of -3. The answer C also has a slope of -3. So those lines would be parallel.
Answer:
7
Step-by-step explanation:
Fiction books: (1/6) of 30 books = 5 books
Non-fiction books: (3/5) of (30) books = 18 books
The subtotal here is 5 + 18, or 23.
23 of the books are either fiction or non fiction.
30 - 23, or 7, of the books remain (are neither fiction nor non-fiction).
