-11b-4-(-b+3)
goes to -11b-4+b-3
=-10b-7
Answer:
After statistical analysis we find that the critical value with respect to a level of significance of 0.01 is greater, we deduce that if there is a difference in the number of rounds played per day in the week
Step-by-step explanation:
120+105+100+150+150=625/5=125= Expected frecuency
(observed - expected)^2/expected
Monday. 120 2
Tuesday. 105. 3.2
Wednesday. 100. 5
Thursday. 150. 5
Friday 150. 5
The total sum will give us the statistical chi-square test that is 20.2
according to the previous listing we look for the degrees of freedom:
5-1=4
Critical value = 3.747
After statistical analysis we find that the critical value with respect to a level of significance of 0.01 is greater, we deduce that if there is a difference in the number of rounds played per day in the week
Answer:
12x -y = -87
Step-by-step explanation:
You can start with the 2-point form of the equation of a line and manipulate it to give you the standard form.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (-9 -3)/(-8 -(-7))(x -(-7)) +3
y = (-12/-1)(x +7) +3
y = 12x +84 +3
-12x +y = 87 . . . . . subtract the x-term
12x -y = -87 . . . . . . make the leading coefficient positive (per standard form)
Answer is 1714 days left.
1st way: 5000-3286
2nd way: 3286+x= 5000
U can use these to solve the problem. :)
