    P value range given t test and degrees of freedom

    Hey guys so I've been using online calculators to convert between the given values and I've only been getting one number, but the problem specifically asked for a range I have a calculated test statistic for a lower-tailed t test with degrees of freedom 15, which is -2.7. The p-value is between...

    The measure of (theta), in degrees, is approximately 34.38 degrees. True or False.

    The measure of (theta), in degrees, is approximately 34.38 degrees.True or False. Using the law of cosine: For 4^2+7^2-5.3^2 it equal 36.91 now for 2ab is that like this 2(4)(7) which equals 56 so is it supposed to look like this 36.91/56 which equals 0.66. (theta)=cos^-1(0.66)...

    Using longitude and latitude, find a point's "vertical latitude" degrees

    Latitude can be defined as forming horizontal parallel planes, whereas longitude forms vertical planes that intersect. I'm interested in finding the vertical parallel planes that are perpendicular to the latitudinal planes. Given a point's longitude and latitude in decimal form, I want to be...

    Trig. Ratios for Angles Greater than 90 degrees.

    1. State all the angles between 0 degrees and 360 degrees that make each equation true. d) tan135 = -tan______________ (there's a blank space here) So, I understand that you have to use the appropriate equation, but the textbook gives two answers in the book, while I only got one. Also, I don't...

    S=Rθ and Circumference * ratio of arc angle to 360 degrees

    I don't know if I'm doing this proof right. But, there are 2 ways to figure out an arc length of a circle s=rθ, and finding the circumference of a circle and multiplying that by the ratio of the angle of the arc/360. So here is my proof, let's start out with the latter method of finding the...
