Fifty specimens of a new computer chip were tested for speed in a certain application, along with 50 specimens of chips with the old design. the average speed, in mhz, for the new chips was 495.6, and the standard deviation was 19.4. the average speed for the old chips was 481.2, and the standard deviation was 14.3.can you conclude that the mean speed of the new chips is greater than that of the old chips?

How many zeros does the function f(x)=4x3-x2+1 have

Describe the end behavior of the function below. f(x)=(2/3)^x-2 a. as x increases, f(x) approaches infinity. b. as x decreases, f(x) approaches 2. c. as x increases, f(x) approaches -2. d. as x decreases, f(x) approaches negative infinity.

Examine the paragraph proof. which theorem does it offer proof for? prove jnm – nmi according to the given information in the image. jk | hi while jnm and lnk are vertical angles. jnm and lnk are congruent by the vertical angles theorem. because lnk and nmi are corresponding angles, they are congruent according to the corresponding angles theorem. finally, jnm is congruent to nmi by the transitive property of equality alternate interior angles theorem gorresponding angle theorem vertical angle theorem o same side interior angles theorem
