Answer:
1cm, 2.4cm, 2.6cm
Step-by-step explanation:
They have to follow the pythagorean theorem a^2+b^2=c^2.
1^2+2.4^2=2.6^2 so it follows the pythagorean theorem so these three squares would form a right triangle.
Answer:
-2
Step-by-step explanation:
10-8=2
8-6=2
6-4=2
4-2=2
Answer:
A.
As x decreases in value, f(x) decreases in value.
As x increases in value, f(x) increases in value.
Step-by-step explanation:
As we move our eyes towards the right following the curve, we see that the y-values are larger and larger. As we move to the right following the curve, the values of the x-variable in the horizontal axis are increasing. Then as x increases, the values of f(x) also increase.
On the other hand, if we move our eyes to the left following the curve, this way looking into what values the function adopts for smaller and smaller values of x, we see that the f(x) values decrease (the curve goes down).
Then, to summarize:
a) As we move to the right, thus increasing the values of x, we see the values of f(x) increase
b) As we move to the left, thus decreasing the values of x, we see the values of f(x) decrease.
Answer:
For the sampling distribution of the sample proportion for a sample of size 50, the mean is 0.061 and the standard deviation is 0.034.
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.
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 
In this question:
So
Mean:
Standard deviation:
For the sampling distribution of the sample proportion for a sample of size 50, the mean is 0.061 and the standard deviation is 0.034.
