20/100 x 8000 = 1600
1600 x 3 = 4800
8000 - 4800 = 3200

The motorcycle is worth $3,200 after three years.

8000-(8000 *.2)=6400
6400-(6400*.2)=5120
5120-(5120*.2)=4096
=
4096

How do you solve<br> -2=u-93÷-3
viktelen [127]

Answer:

u=91

Step-by-step explanation:

-2=u-93÷-3

multiply both sides by 3

3(-2)=(u)3+(-93÷-3)3

-6=3u-279

add 279 to both sides

-6=3u-279

+279. +279

273=3u

divide by 3

273÷3=3u÷3

91=u

Prove triangle AOC is congruent to triangle BOD​
marta [7]

Step-by-step explanation:

We are given two Triangles and we need to prove them congruent . In ∆AOC and ∆BOD , we have

\to AC = BD ( given ) \\\\\to OD = OA \\\\\to \angle CAO =\angle BDO (Since\ BD || AC )

Therefore by AAS congruent condition we can say that ,

\implies\red{ \triangle AOC \cong \triangle BOD }

Hence Proved!

A sociologist recently conducted a survey of senior citizens who have net worths too high to qualify for Medicaid but have no pr
hjlf

Answer:

a) s= 9.74

D. 9.74

b) Median= 74

B. 74

Step-by-step explanation:

Part a

We have the following dataset given:

69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83

We can begin calculating the sample mean with the following formula:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

And replacing we got:

\bar X = 75.04

Now we can calculate the sample deviation with the following formula:

s =\sqrt{\frac{\sum_{i=1}^n (X_i-\bar X)^2}{n-1}}

And after replace we got:

s= 9.74

Part b

For this case we need to sort the value on increasing way:

[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93

And the median would be the value in the position 13 and we got:

Median= 74
