Answer:
C) Both
Step-by-step explanation:
The given equation is:
To solve the given equation, we can use the Zero Product Property according to which if the product <em>A.B = 0</em>, then either A = 0 OR B = 0.
Using this property:
So, Erik's solution strategy would work.
Now, let us discuss about Caleb's solution strategy:
Multiply 
i.e. 
= 
So, the equation becomes:
Comparing this equation to standard quadratic equation:
a = 3, b = -10, c = -8
So, this can be solved using the quadratic formula.
The answer is same from both the approaches.
So, the correct answer is:
C) Both
Answer:
The answer is 2.5
Step-by-step explanation:
each cube has a volume of 0.125 and the cube can hold 20 of them.
0.125 * 20 = 2.5
Red Perimeter= 4u X π= 4uπ
Blue Perimeter= u X π= uπ
Red Area= 2u X 2u X π= 4u2π
Blue Area= u X u X π= u2π
Answer: The probability in (b) has higher probability than the probability in (a).
Explanation:
Since we're computing for the probability of the sample mean, we consider the z-score and the standard deviation of the sampling distribution. Recall that the standard deviation of the sampling distribution approximately the quotient of the population standard deviation and the square root of the sample size.
So, if the sample size higher, the standard deviation of the sampling distribution is lower. Since the sample size in (b) is higher, the standard deviation of the sampling distribution in (b) is lower.
Moreover, since the mean of the sampling distribution is the same as the population mean, the lower the standard deviation, the wider the range of z-scores. Because the standard deviation in (b) is lower, it has a wider range of z-scores.
Note that in a normal distribution, if the probability has wider range of z-scores, it has a higher probability. Therefore, the probability in (b) has higher probability than the probability in (a) because it has wider range of z-scores than the probability in (a).
