Answer:
New balance = 3640
Step-by-step explanation:
Given the following data;
Interest rate = 4% = 4/100 = 0.04
Principal = 3500
To find the new balance;
First of all, we would find the amount at the interest rate;
New amount = interest rate * principal
New amount = 0.04 * 3500
New amount = 140
Now, to find the new balance;
New balance = principal + new amount
New balance = 3500 + 140
New balance = 3640

Answer:
The ballon will hit the ground after 1 s.
Step-by-step explanation:
In this case we want to solve for x, but were given a equation to the height of the ballon, we can organize it in a way that isolates x on the left side of the equation so it can be used to what we want. So we have:
h = -16x^2 +16
h + 16x^2 = 16
16x^2 = 16 - h
x^2 = (16 - h)/16
x = sqrt(16 - h)/sqrt(16) = sqrt(16 - h)/4
When the ballon hits the ground it's height is 0 feet, so we substitute that on our equation and we'll have the right answer.
x = sqrt(16 - 0)/4 = sqrt(16)/4 = 4/4 = 1 s
Answer:
mean=13.2
median=13
mode=14
Step-by-step explanation:
mean=sum of values/number of values
sum of values=9+17+14+12+14+14+9+11+10+20+10+22+11+11+9+15+14+15=237
number of values=18
mean=237/18=13.17
Mean=13.2
Arranging data in ascending order
9 9 9 10 10 11 11 11 12 14 14 14 14 15 15 17 20 22
n/2=18/2=9 is an integer so,
median= the average of (n/2)th and (n/2 +1)th observation
median=(12+14)/2=26/2=13
Median=13
Mode= The most repeated observation in the data
14 is repeated more than other numbers so, 14 is the mode for this data.
Mode=14
