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).
Answer: 1884 cm³
Step-by-step explanation:
cylinder volume = π · r² · h
- h = height = 24 cm
- r = radius = 5 cm
- π = pi ≈ 3.14
π · r² · h = 3.14 · 5² · 24 = 3.14 · 25 · 24 = 1884 cm³
Answer:
4 bags of gold coins and 6 bags of gold coins
Step-by-step explanation:
So, Becky has 9 bags of coins
This is basically a "trial and error" equation.
Now, she has 4 bags of 8 gold coins
8×4= 32
So she has 32 gold coins
Now, she has 5 bags of 6 silver coins
5×6=30
So she has 30 silver coins.
So we add these,
30+32= 62
HOPE THIS HELPS!!!
If the discriminant(b^2-4ac) is rational, then the quadratic is rational.

Some people find this helpful to picture or draw on a number line. Start at zero, go left to -5. Go 2 more spaces/marks left to -7, then go right three spaces to -4.
