"SAS" is how you find the angle in between. Use the law of cosines to calculate the unknown side, then use the law of sines to find the simuliar of the other two angles, then use three angles add to 180 degrees to find the last angle.
The value of the expression is not divisible by 30 and 44.
<u>Explanation:</u>

To check the number -25400 be divisible by 30 and 44, divide the number -25400 by 30 and 44
On dividing -25400 by 30 we get, -846.66
On dividing -25400 by 44 we get, -577.27
Therefore,
The value of the expression is not divisible by 30 and 44.
Answer:
(e) the mean number of siblings for a large number of students has a distribution that is close to Normal.
Step-by-step explanation:
Central Limit Theorem
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.
By the Central Limit Theorem
The sampling distributions with a large number of students(at least 30) will be approximately normal, so the correct answer is given by option e.
Answer:
15 times the first equation and -12 times the second equation
Step-by-step explanation:
we have
------> first equation
------> second equation
Multiply the first equation by 15 both sides

-----> new first equation
Multiply the second equation by -12 both sides

-----> new second equation
Adds the two new equations

The y-term was eliminated
