Answer:
here's one way: z^x = Y, 7^1 = 7
Y = 7
Step-by-step explanation:
Answer: LAST OPTION.
Step-by-step explanation:
For this exercise it is important to remember that, by definition, the angle formed by two secants intersecting outside of a circle, can be found with the following formula:
According to the information provided in the exercise, you know that:
Therefore, you can find the difference of the intercepted arcs:
The final step is to substitute the difference of the intercepted arcs calculated above, into the formula, in order to find the measure of the angle BED.
You get that this is:
Answer:
B. Events H and C are dependent and P(H|C) < P(C|H)
Step-by-step explanation:
The ratios of groups with children to hiking groups on the trail are different for the two trails.
P(H|C) = 15/45 = 1/3
P(C|H) = 15/40 = 3/8
1/3 < 3/8 so the comparison of choice B is appropriate.
