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: A would be angle "O" sine both triangle PNO and LMO share the same angle
S would be ON = LM ( as shown)
A would be angle "L" and angle "N" or angle "P" and angle "M" ( the side is opposite of each other)

Step-by-step explanation:
Answer:
102
Step-by-step explanation:
Each triangle will have a perimeter of 3. When joined, the outside triangles will have 2 sides showing, or 2 inches. The middle 98 will only have one free side, or one inch. This means that 98*1 + 2*2 = 102
Answer: 120,000
Step-by-step explanation:
Let the question mark = x
x*1/100 = 1200
Multiply by 100 on both sides:
x = 1200*100
x = 120,000
Answer:
x = 9
Step-by-step explanation:
10x - 8 = 82
+ 8 + 8
10x = 90
/ 10 / 10
x = 9
