Answer:
2x
Step-by-step explanation:
10x/5 is the same as 1/5 times 10x.
Simplify to get 2x
Answer:
The place value to which the number is rounded is unit place.
Step-by-step explanation:
Here, the number 3.695 is rounded to the number 4 and we have to name the place value to which the number is rounded.
Here, the place value to which the number is rounded is unit place.
And the name of the rounding is the rounding to the nearest whole number i.e. there will be no fractional part in the rounded number.
Another example is the number 0.917 is rounded to the nearest whole number to give 1. (Answer)
<em>Answer:</em>
<em>n = 12</em>
<em>Step-by-step explanation:</em>
<em>85%×n = 10.2</em>
<em>85n/100 = 10.2</em>
<em>85n = 1020</em>
<em>n = 1020 : 85</em>
<em>n = 12</em>
Answer:
To obtain a valid approximation for probabilities about the average daily downtime, either the underlying distribution(of the downtime per day for a computing facility) must be normal, or the sample size must be of 30 or more.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation
