Welcome to the Bronco Telephone Services. You have been assigned to figure out how many area codes are possiblel, thus advising the company whether they need more restrictions or not. Bronco Telephone Services would like at least 175 area codes with a few to assign later on. The area code is in the FORM of NYZ
N can have any digit from 2 to 9. Y can have only 1, or 2. Z is 1-9, when Y=1. And Z is 2-9 when Y=2. How many area codes are possible with these parameters? A.) 136 B.) 192 C.) 120 D.) 200

For the quadratic function [tex]y=(x+4)^2-1[/tex] , do the following: a) rewrite the function in the standard form, b) rewrite the function in intercept form, c) find the vertex, d) find the y-intercept, e) find the x-intercepts.

Ok a point t on a segment with endpoints d(1, 4) and f(7, 1) partitions the segment in a 2: 1 ratio. find t. you must show all work to receive credit.

Two researchers are attempting to create a new psychotherapy protocol that more reduces panic attacks. they believe that they have succeeded and are now in the clinical trial period of their protocol's development. they are working with several cohort groups, some of which have been through the new protocol, while others have done the standard protocol currently recommended. if these researchers are interested in evaluating the difference in the percentage of test subjects who successfully decreased their panic attacks in 2 months on the new protocol versus the percentage of test subjects who successfully decreased their panic attacks in 2 months with the traditional protocol, which of the following statistical tests would be most appropriate? a. analysis of variance (anova) b. correlation c. chi-square test d. paired t-test e. independent t-test
