Consider a small scale example, comparing how temperatures have changed in the us from1968 to 2008. the daily high temperature reading on january 1 was collected in 1968 and 2008 for 51 randomly selected locations in the continental us. then the difference between the two readings (temperature in 2008 - temperature in 1968) was calculated for each of the 51 different locations. the average of these 51 values was 1.1 degrees with a standard deviation of 4.9 degrees. we are interested in determining whether these data provide strong evidence of temperature warming in the continental us. (does the data provide evidence that the true mean temperature is greater in 2008 than in 1968? ) justify fully at the 5% significance level.

Which triangle congruence postulate or theorem justifies my claim that the steps i made using construction paper and scissors produce an isosceles triangle? was it sss, sas, asa, aas, or hl?

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function. how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
