Answer:
Martina 29, Scott 23 and Jim 69.
Step-by-step explanation:
We are told that:
Martina served six more X orders than Scott (X+6).
So, Scott served X orders.
And Jim served 3 times X order as Scott.
We will have then:
X + (X+6) + 3X = 121
5X + 6 = 121
5X = 121 - 6
5X = 115
X = 115/5
X = 23
So, Scott served 23 orders, Martina 29 and Jim 69.
Answer:
A
Step-by-step explanation:
A its A i ssssssssseewwwwaaarrrrrr
M(slope)= -5/4 point-slope(y-y1=m(x-x1)) so it would be y-5= -5/4(x+4)
Rational ! the number doesn't repeat forever or anything like that. it simplifies nicely.
Complete Question
A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthorn wand has a price of 45.20. What proportion of wand prices are lower than the price of the blackthorn wand? You may round your answer to four decimal places
Answer:
0.1151
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = $45.20
μ is the population mean = $50
σ is the population standard deviation = $4
We are solving for x < 45.20
Hence:
z = 45.20 - 50/4
z = -1.2
Probability value from Z-Table:
P(x<45.20) = 0.11507
Approximately to 4 decimal places = 0.1151
Therefore, the proportion of wand prices that are lower than the price of the blackthorn wand is 0.1151
