Answer:
A. 0.0001
Step-by-step explanation:
z-statistic:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
The value of the z-statistic is z = 3.74.
The desired probability is 1 subtracted by the pvalue of z = 3.74.
z = 3.74 has a pvalue of 0.9999
Then
1 - 0.9999 = 0.0001.
So the correct answer is given by option A.
Between emma and dave, we have 7/10ths of the money
3x + 2x = 7/10
5x = 7/10
x=(7/10)/5
x= 14/100
Dave will get 28/100 or 7/25ths
Check : 30/100 Colin
42/100 Emma
+ 28/100 Dave
-----------
100/00
2/5 because if I simplified thatbis what u are gonna get
The correct answer (the one that isn't true) is the last one, "angle 1 and angle 2 are equal"
