Answer:
Removing the outlier decreases the number of data by one and therefore you must decrease the divisor. For instance, when you find the mean of 0,10,10,12,12, you must divide the sum by 5, but when you remove the outlier of 0,you must then divide by 4.
Step-by-step explanation:
No map given but it shouldn't matter.
E is the 5th letter, L the 12th.
Start at S(6,12). End at E(10,5)
The vector between them, E-S=(4,-7)
Each unit is 1/16 of a mile, though that probably doesn't matter that much.
Doug has to stay on the grid, so has to run |4|+|7|=11 units. At 30 mi/hr that takes (11/16)/30 = 0.022916 hours.
Bert can go diagonally, so flies √(4²+7²)=√65 ≈ 8.06 units. At 20 mi/hr that takes (8.06/16)/20 = 0.025194 hours.
Answer: Doug wins
Why? Because it's quicker to cover 4+7 at 30 mph than it is to cover √(4²+7²) at 20 mph. That is, Doug is 1.5 times faster and the 1.5 times the diagonal distance is more than the grid distance.
Answer:
Step-by-step explanation:
Firstly convert each number into an improper fraction. 2 1/4 would become: 9/4 (because we multiply 2 and 4 and plus the numerator, to get the numerator and keep the denominator the same). Do this to all the numbers then multiply the numerator by the numerator and the denominator by the denominator. simplify normally and convert to a mixed number.
Answer:
Her rent is $1072.5
Step-by-step explanation:
Monthly budget: $3,575
Her rent is 30% of her monthly budget. Since 30% = 0.3, we can multiply our monthly budget with 0.3 to get 30% of it.
30% * 3575 = 0.3 * 3575 = 1072.5
Answer: $1072.5
