Step-by-step explanation:
Ten pairs of points yielded a correlation coefficient r of 0.790. If a =0.05, which of the following statements is correct if H.: P = 0? (Do not calculate a t-value.) A) Because 0.790 is greater than 0.632, the nullliy pothesis is not rejected. Because 0.790 is greater than 0.602, che null hypothesis is not rejected. Because 0.790 is greater than 0.632, che null hypothesis is rejected. OD) There is no correlation between the variables
2a
3c
4b
Cross multiply for 2
Put 4x-5=3x-10 and subtract 3 on both sides. After that add 10 to both sides for 3
Divide everything by 5 and multiply everything by -2 for 4
Answer:
D=6
Step-by-step explanation:
A quick and easy way to find the distance between these points is to use the distance formula: d= √(x2-x1)^2 + (y2-y1)^2, where (x1,x2) and (y1,y2) are the coordinates of the first and second point. (It doesn't matter which point is (x1,x2) or (y1,y2), just stay consistent)
Plug in the coordinates:
d= √(0-(-6)^2+ (8-8)^2
Simplfy
d=√(6)^2+(0)^2
d=√36
d= 6
Answer:
65,000
Step-by-step explanation:
You take 64800 and use the 8 to round the 4 up, and u get 65000.
7 thousand = 700 hundreds 10 tens
7,000÷10=700
