7/8 / 11/12. First get the reciprocal of 11/12 (which is 12/11). Then multiply by the reciprocal. 7/8 * 12/11 = 84/88
don't forget to simplify
21/22
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:
Would take 1.48 x 10¹¹ years to cross the galaxy
Step-by-step explanation:
galaxy is estimated to be 5.6 × 10¹⁹ mi across = Distance
spaceship traveling at 43,000 mph = Speed
From Speed = Distance / Time
∴ Time = Distance / Speed
= 5.6 × 10¹⁹ / 43,000
= 5.6 × 10¹⁹ / 4.3 x 10⁴
= 5.6/4.3 x 10¹⁹ ⁻ ⁴
= 1.3 x 10¹⁵ hours
Convert time in hours to years
Asuming 24 hours make a day and 365days make a year
= 1.48 x 10¹¹ years to cross the galaxy
if I had enough money, of course I will have change.
