Answer: 3,240,000 L
Explanation:
Each tree requires 20 L of water per day for 180 days.
Each tree therefore requires;
= 20 * 180
= 3,600 L per day
There are 900 trees to be grown;
= 900 * 3,600
= 3,240,000 L of water are required for 900 trees.
I don’t see answer choices but it does sound similar to confirmation bias.
Answer: 93
Explanation:
Firstly, we need to know the rural.scire for the 4 tests. Since the mean for the 4 tests is a 92, the total score will be:
= 4 × 92
= 368
Since we want to know the score for he 4th test, we add the score for the 3 tests that she remembers and subtract from 368. This will be:
= 368 - (100 + 95 + 80)
= 368 - 275
= 93
She had 93 in her last test.
What the data means about the amount of money people spend on purchasing accessories for the their mobile phones is that;
on the average, people spend between 43 and 57 dollars on every accessory they buy.
<h3>Confidence Interval</h3>
We are told that;
Mean is $50
Standard deviation from the mean is $7
From the empirical rule, since standard deviation from the mean is $7, then we can conclude that the confidence interval is;
CI = 50 ± 7
CI = (50 - 7), (50 + 7)
CI = (43, 57)
In conclusion, this means that on the average, people spend between 43 and 57 dollars on every accessory they buy.
