So average=(total of scores)/(number of tests)
needs at least average of 70
at least is represented as greater than or equal to or the sign (<u>></u>)
70<u>></u>(total)/(number oftests)
since we have 3 tests, we have to have 3 scores so
70<u>></u>(x+y+z)/3
he scored 85 and 60
70<u>></u>(x+85+60)/3 (doesn't matter which to subsitute)
70<u>></u>(x+145)/3
multiply obht sides by 3
210<u>></u>x+145
subtract 145 from both sides
65<u>></u>x
he needs to get at leas 65 on his third test
(x+q) = r/p
x+q = r/p
x = (r/p) - q
Answer:
No, he is wrong.
Step-by-step explanation:
Since, the total payment of a loan after t years,
Where,
P = present value of the loan,
r = rate per period ,
n = number of periods,
Given,
P = $165,000,
In loan 1 :
r = 3% = 0.03, t = 15 years,
So, the total payment of the loan is,
In loan 2 :
r = 4% = 0.04, t = 30 years,
So, the total payment of the loan is,
Since, 
Hence, total amount repaid over the loan will be less for Loan 1.
That is, the friend is wrong.
It said "no association between this dude winning and loss in harsh condition"
now look at harsh condition, total is 20, since there is no association that means they are the same, which is 10 and 10
WIN column total is 168, 158 for normal condition, 10 for harsh condition, adds up to 168.
LOSS column total is 72, 62 for normal condition and 10 for harsh condition, adds up to 72.
if u wana check if it adds up with Normal Condition, 62 plus 158 is 220.
checked, complete, this is david signing off
