Answer:
The sum of the first 18 odd positive integers is 324.
Step-by-step explanation:
Given : The first 18 odd positive integers.
To find : The sum of the first 18 odd positive integers?
Solution :
The odd positive integers are 1,3,5,.... forming an Arithmetic sequence .
Where, First term is a=1
Common difference is d=2
Number of terms n=18
The sum of A.P formula is
![S_n=\frac{n}{2}[2a+(n-1)d]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D)
Substitute the values in the formula,
![S_{18}=\frac{18}{2}[2(1)+(18-1)2]](https://tex.z-dn.net/?f=S_%7B18%7D%3D%5Cfrac%7B18%7D%7B2%7D%5B2%281%29%2B%2818-1%292%5D)
![S_{18}=9[2+(17)2]](https://tex.z-dn.net/?f=S_%7B18%7D%3D9%5B2%2B%2817%292%5D)
![S_{18}=9[2+34]](https://tex.z-dn.net/?f=S_%7B18%7D%3D9%5B2%2B34%5D)
![S_{18}=9[36]](https://tex.z-dn.net/?f=S_%7B18%7D%3D9%5B36%5D)

Therefore, The sum of the first 18 odd positive integers is 324.
Answer:
$29500
Step-by-step explanation:
Given data
The number of months is 60
the downpayment is $5,500
the monthly payment is $400
Let the function for the total payment be given as
y=mx+c
y= 400(60)+5500
y=24000+5500
y= 29500
Hence the total paid for the car is $29500
Answer: I get c, but double check on your end
Step-by-step explanation:
The easy way is to count outcomes. Of the 36 equally probable outcomes, 10 are less than or equal to 5, so the probability is 10/36 = 5/18.
Answer:
x=-2
Step-by-step explanation:
Consider equation -11=5+8x
Collecting the like terms
-8x=11+5, -8x=16
Dividing through by -8 ob both sides of the equation
(-8x)-/8=16/-8
x=-2
