Answer: C. 47 degrees
Step-by-step explanation:
85+48=133
All triangles interior angles are equal to 180
180-133=x
180-133=47

Step-by-step explanation:
We need to find the number of bucks
4 does + 3 fawns + x bucks = 10
4 + 3 +x = 10
7+ x = 10
Subtract 7 from each side
x = 3
There are 3 bucks
3/10 is the fraction of bucks
Multiply the top and bottom by 2
3/10 * 2/2 = 6/20 is an equivalent fraction
Answer:
Step-by-step explanation:
The given equation is:
,
Now, putting x=2 in above equation,


Now, put y=3 in the given equation,



Putting x=6,



Putting x=0,


Putting x=3,



Putting y=0,


Putting y=8,



Answer:
5
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:

On average, how much error would be expected between the sample mean and the population mean?
This is the standard deviation of the sample. We have that
. So

The answer is 5.
