Answer:
2
Step-by-step explanation:
12.80=6.4x
12.8/6.4=2
x=2
Answer:
Step-by-step explanation:
Assuming a normal distribution for the amount spent by Canadian households for high-speed broadband access, the formula for normal distribution is expressed as
z = (x - u)/s
Where
x = amount spent by the Canadian households.
u = mean amount spent monthly.
s = standard deviation
From the information given,
u = $80.63 CDN
s = $27.32 CDN
We want to find the probability that the average amount will exceed $85. It is expressed as
P(x greater than 85) = 1 - P(x lesser than or equal to 85)
For x = 85
z = (85 - 80)/27.32 = 0.18
Looking at the normal distribution table, the corresponding z score is 0.57142
P(x greater than 85) = 1 - 0.57142 = 0.43
Answer:
Rodney will have 9 toffees more than Micah.
Step-by-step explanation:
Let the numbr of toffee Micah have = x
So, the number of toffee Rodney have = x + 7.
Since, Micah's father gave him 2 more toffees.
Then, number of toffee Micah now have = x + 2
<em>So, number of toffees Rodney will have = (x+7) + 2 = x + 9.</em>
Hence, Rodney will have 9 toffees more than Micah.
Hundred is: 600
ten is: 620
