Q1. Kay is organising an exhibition on health and beauty. The exhibition will be open from 11 am to 4 pm. There will be
3 different exhibition rooms with presentations
A lunch break for 45 minutes
I
A coffee break for 30 minutes.
Lunch and coffee will be served in the restaurant.
Kay wants people to spend an equal amount of time in each exhibition room. She thinks this means
people will spend at least 1 hour 20 minutes in each exhibition room.
Is Kay correct? Show why you think this.

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?

One positive integer is 2 less than another. the product of the two integers is 24. what are the integers?

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
