If you invest 3,500 in a savings account that pays 4% simple interest how much will the new balance be after including interest?
garik1379 [7]

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

A water balloon is dropped from a height of 16 feet. The function h=-16x^2+16 gives the height h of the balloon after x seconds.
Lerok [7]

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

How large is a wolf pack? The following information is from a random sample of winter wolf packs. Winter pack size are given bel
Olenka [21]

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
