Step-by-step explanation:
what is the problem ? what needs to be done ?
all that you are showing here is the definition of a number range.
it means all numbers, for which 1.3 is smaller or equal.
in short, all numbers that are greater or equal to 1.3.
7B+5Y=487B+1Y=40Subtracting Eqn 2 from 1 we get 4Y=8so Y = $2 and X=$38/7
18 hours = 18/24 reduces to 3/4 of a day
3/4 = 0.75
so 3600/3.75 = 960 watts per day
Answer: Option (c) is correct.
68% of the data points lie between 10 and 18.
Step-by-step explanation: Given : a normal distribution with a standard deviation of 4 and a mean of 14
We have to choose the sentence that correctly describes a data set that follows a normal distribution with a standard deviation of 4 and a mean of 14.
Since, given 68% data.
We know mean of data lies in middle.
And standard deviation is distribute equally about the mean that is 50% of values less than the mean and 50% greater than the mean.
So, 68% of data lies
mean - standard deviation = 14 - 4 = 10
mean + standard deviation = 14 + 4 = 18
So, 68% of the data points lie between 10 and 18.
