The sum of your data set is 23.8333333333.All you have to do is add them all together and then divide by 6, which is the number of numbers there are.

8+13+17+26+32+47=143
143/6+23.8333333333

Add all the numbers in the data set
8+47+13+17+26+32
= 143
divide it by the the present amount of numbers ( 6 )
143 / 6 = 23.83 (infinite 3s i think)

M is the incenter of triangle ABC. Find the lengths of MD and DC. (Look at pic)

Deffense [45]

Answer:

Part 1) $MD=9\ units$

Part 2) $DC=12\ units$

Step-by-step explanation:

Step 1

Find the length of MD

we know that

The incenter is the intersection of the angle bisectors of the three vertices of the triangle. Is the point forming the origin of a circle inscribed inside the triangle

In this problem

$MD=ME=MF$ ------> is the radius of a circle inscribed inside the triangle

we have that

$MF=9\ units$

therefore

$ME=9\ units$

$MD=9\ units$

Step 2

Find the length of DC

we know that

In the right triangle MDC

Applying the Pythagoras theorem

$MC^{2} =MD^{2}+DC^{2}$

we have

$MD=9\ units$

$MC=15\ units$

substitute

$15^{2} =9^{2}+DC^{2}$

$DC^{2}=225-81$

$DC=\sqrt{144}\ units$

$DC=12\ units$

How much interest is earned in 2 years on an investment of $2000? The interest rate is 3%

erik [133]

Answer:
A = $ 2,120.00

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation

A = 2000(1 + (0.03 × 2)) = 2120
A = $ 2,120.00

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 2,000.00
at a rate of 3% per year
for 2 years is $ 2,120.00.

Find the least common denominator of 7 and X+4 x-4

Effectus [21]

(X+4)(X-4) is the LCD because you just have to look at the denominators and see what factors or values are not already part of your LCD.
