Standard form is f(x)=ax^2+bx+c
order of power
f(x)=2x^2-11x+2
Answer:
(B) Because the confidence interval includes 0, we don't have convincing evidence that sugar causes faster reading times, on average.
Step-by-step explanation:
Confidence Interval for the population mean difference in reading is basically an interval of range of values where the true population mean difference in reading time can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample mean) ± (Margin of error)
In using confidence interval of population mean difference in reading times for hypothesis testing, if the interval obtained contains a value of 0, it means the population mean difference in reading times can take on a value of 0 and indicate that there isn't enough evidence to conclude that there is a significant difference in the two quantities being compared. (The null hypothesis is true).
If the interval doesn't contain a 0, then it can be concluded that there is enough evidence to conclude that there is significant difference in the two quantities being compared.
Hope this Helps!!!
Answer:
40
112
2n^2 + 2n C
Step-by-step explanation:
a)The correct formula is 2n^2 + 2n
So for n =4, the answer is
2*4^2 + 2*4
2*16 + 8
32 + 8
40
b) For the seventh answer you get
2 * 7^2 + 2*7
2*49 + 14
98 + 14
112
c) The correct formula to use is
2n^2 + 2n See diagrams for the number of matchsticks to be used.
n 2n^2 + 2n
1 2*1^2 + 2*1
1 2 + 2
1 4
2 2*2^2 + 2*2
2 2* 4 + 4
2 8 + 4
2 12
3 2*3^2 + 2*3
3 18 + 6
3 24
What an extremely interesting sequence. I'll bet not one person in 100 could get this without the match stick diagrams. I'm sorry I didn't read the question more carefully.
