Yes it does have a great day
First of all, to find the slope, you need to subtract the y's in the numerator over the x's in the denominator. Then you use Y-Y₁=slope(X-X₁) using either of the two points. If you want to simplify it further into slope-intercept form, you need to distribute on the right side of the equation.
Answer:
Step-by-step explanation:
Since the amount of soft drink dispensed into a cup is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = amount in ounce of soft drink dispensed into cup.
µ = mean amount
σ = standard deviation
From the information given,
µ = 7.6oz
σ = 0.4 oz
a) The probability that the machine will overflow an 8-ounce cup is expressed as
P(x > 8) = 1 - P(x ≤ 8)
For x = 8,
z = (8 - 7.6)/0.4 = 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.84
P(x ≤ 8) = 1 - 0.84 = 0.16
b) P(x< 8) = 0.84
c) when the machine has just been loaded with 848 cups, the number of cups expected to overflow when served is
0.16 × 848 = 136 cups
Answer:
is there a formula in the notes if so put it in then it might help out
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
firstly you have to find the rate of change of the various price index in percentage.
A, From 106 to 112:
we find the difference 112-106 = 6
then the rate of change = 6/106 * 100 = 5.66%.
B ,From 112 to 118:
we find the difference 118-112 = 6
then the rate of change = 6/118 * 100 = 5.36%.
C ,From 118 to 124:
we find the difference 124-118 = 6
then the rate of change = 6/124 * 100 = 5.08%.
we can see that the price index with the greatest percentage is A.
