Answer:
x=4 or x= - 16
Step-by-step explanation:
|x+6|
Now subtract 7 which equals to 3.
|x+6|-7=3
|x+6|=10
Now remove the mode by adding plus minus sign in the front of 10.
x+6=±10
x+6=10 or x+6=-10
x=4 or x=-16
Answer:
The mean of the sampling distribution of the sample mean alcohol consumption is of 5.70 alcoholic drinks per week and the standard deviation is 0.13 alcoholic drinks per week
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, we have that:
The mean of the sampling distribution of the sample mean alcohol consumption is of 5.70 alcoholic drinks per week and the standard deviation is 0.13 alcoholic drinks per week
Answer:
67-32=a
if his mom is 67 and he is 32 years younger 67 minus 32 would equal a which is his age
You fist multiply the area by two. Then you divide that by the height.
