Total number of $1 bills=7
Total number of $5 bills=8
Further explanation:
Given
Let x be the number of $1 bills
and
y be the number of $5 bills
Then according to the given statements
x+y=15
x+5y=47
From first equation:
Putting x=15-y in second equation
Putting y=8 in first equation
Hence,
Total number of $1 bills=7
Total number of $5 bills=8

Answer:
C.) False, counterexample of 15
1) 15 is divisible by 3 but not by 6
we know that 15 = 3*5 or 15/3=5, So 15 IS DIVISIBLE BY 3
BUT 15/6=2.5 THIS PROVES 15 IS NOT PERFECTLY DIVISIBLE BY 6
2) 12= 3*4 & 6*2
SO 12 IS PERFECTLY DIVISIBLE BY 3 & 6 BUT 15 IS NOT. THUS THE ANSWER IS 'C'
Answer:
0.53347
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score = -0.084 °C
μ is the population mean = 0 °C
σ is the population standard deviation = 1°C
Z score =x - μ/σ
= -0.084 - 0/1
= -0.084
Probability value from Z-Table:
P(x<-0.084) = 0.46653
P(x>-0.084) = 1 - P(x<-0.084) = 0.53347
The probability of obtaining a reading greater than -0.084°C = P(x > -0.084) =
is 0.53347
