Answer:
A regression coefficient is the same thing as the slope of the line of the regression equation.
Step-by-step explanation:
The equation for the regression coefficient that you'll find on the AP Statistics test is: B1 = b1 = Σ [ (xi – x)(yi – y) ] / Σ [ (xi – x)2].
You can use 920 divided by 20. This would give you 46. You get 920 by Round 921 to the nearest tens. You also get 20 by rounded it to the nearest tens
Rate of change is Rise over run=3/36=1/12 inches
Answer:
7280000000 or 7.28^9 (in scientific notation)
Step-by-step explanation:
this question is asking you to transfer numbers out of scientific notation and multiply them. 10^6 is 1 followed by 6 zeros (good trick to remember) or 1000000. when you multiply anything by a power of 10 you just add that many zeroes to it or move the decimal point one point to the left for every zero. so in this example it is 5.2 times 1000000 which is 5200000. we do the same for the other one and we get 1400. When we multiply these two values we get 7280000000 or 7.28^9
