To solve this problem, you'd want to start by finding the mean of the given numbers. To find the mean, add all the numbers together and divide by how many there are.
Next, you'll see that the question says one of the rents changes from $1130 to $930. So find the mean of all the numbers again, except include $930 in your calculation instead of $1130.
I got $990 as the mean for the given numbers, and $970 as the mean after replacing the $1130 with $930. Subtracting the two means gives you $20. So the mean decreased by $20.
Now for the median, all you need to do is find the median of the given numbers and compare them with the median of the new data. Because there are ten terms, you have to add the middle two numbers and divide by two. $990 + $1020 = 2010. 2010÷2 = $1005 as the first median.
The new rent is 930, so you have to reorder the data so it goes from least to greatest again. 745, 915, 925, 930, 965, 990, 1020, 1040, 1050, 1120. After finding the median again you get 977.5. Subtracting the two medians gives you $27.5 as how much the median decreased. Hope this helps!
Answer:
The boat traveling at 24 kph when John goes downstream.
Step-by-step explanation:
We are given the following in the question:
John has a boat that will travel at the rate of 15 kph in still water.
Let x be the speed of the current.
Speed of boat in upstream
Speed of water in downstream
Relation:
We have to find the speed of boat in downstream.
Time to travel upstream for 35 km = Time to travel 140 km downstream
Thus, speed of current is 9 kph.
Speed of boat in downstream = 15 + 9 = 24 kph.
Thus, the boat traveling at 24 kph when John goes downstream.
Answer:
Change in height of the parasail after 5 minutes = 79.8 feet.
Explanation:
Change in height = Absolute value of the differences of the initial height and final height.
Initial height of parasail = 200.6 feet.
Final height parasail = 120.8 feet.
Change in height of the parasail = 200.6 - 120.8 = 79.8 feet.
Change in height of the parasail after 5 minutes = 79.8 feet.
Answer:
A) 
B) $1200
Step-by-step explanation:
Let w represent employee's weekly sales and 
be total weekly earnings.
We have been given that a phone store employee earns a salary of $450 per week plus 10% commission on her weekly sales.
A) The total weekly earnings of employee would be weekly salary plus 10% of weekly sales.
10% of weekly sales, w, would be 
Therefore, the function models the employee's weekly earnings.
B) To find the weekly sales in the week, when employee earned $570, we will substitute 
in our formula and solve for w as:
Therefore, the amount of employee's weekly sales was $1200.
Given:
13% calories from added sugar
270 calories
To get the total amount of calories, we need to divide the part by its corresponding percentage.
270 calories ÷ 13% = 2,076.92 calories.
=2,076.90 CALORIES
