Answer:
The square root of 68 is 2 √ 17 in the simplest radical form.
Step-by-step explanation:
It cannot be simplified further. √ 17 is an irrational number, therefore, the square root of 68 is an irrational number.
Answer:
16
Step-by-step explanation:
If 3 x 4 = 12 then you need to do the same to the number 4 so 4 x 4 =16
Answer: <em>is it 4, maybe?</em>
Answer:
The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours
Step-by-step explanation:
The Central Limit Theorem estabilishes 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.
In this problem
The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours
Answer:
120 units²
Step-by-step explanation:
The area can be found using the formula for the area of a triangle:
A = 1/2bh
Since the sides of length 10 and 24 are at right angles, either can be considered to be the base and the other the height. Then the area is ...
A = 1/2·(10 units)·(24 units) = 120 units²
