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.
Answer:
Because the confidence interval includes zero, the researcher can conclude the proportion of men and women who exercise regularly may be the same.
Explanation:
When constructing a two-proportion z-interval, it is important to look for the value zero. A value of zero in the interval shows there is no difference in the proportions between the two populations.
If the interval contains all positive numbers, it implies the true proportion for sample 1 is greater than that for sample 2. If the interval contains all negative numbers, it implies the true proportion for sample 1 is less than that for sample 2.
Answer:
The right approach is "Nature abhors a vacuum."
Explanation:
- A siphon operates whenever the gravity pushing down the larger column allows the weight upon that edge of something like the siphon to decrease.
- Whenever fluid grows deeper throughout the pool, pressure upon that contained temperature rises or increases, and perhaps the liquid gets outside the trap's deep midwicket.
Above there is indeed the perfect method.
