Answer: B. 31
Step-by-step explanation:
This linear regression was constructed by relating the hours practiced per week and the number of competitions won.
Going by this graph, the number of competitions they can expect to win at 5 practices a week is 31.
This is derived by looking for the point where 5 competitions on the x-axis intersects with the line. This point is at 31 competitions on the y axis which would make it the answer.
Answer:
x-intercept: 0,-1 . y-intercept: -1.5,0
Step-by-step explanation:
When given a point-slope equation y-y=m(x-x), the second x and y values mark a point in the line and the m value is the slope (rise over run). Just graph the line from there (in this case the slope would be 2 down and 3 to the right).
Answer:
56/40 + 15/40 = 71/40
Step-by-step explanation:
Divide 100 to 56 = 56/100= 0.56 then you wanna times it by 50 so then it would be.56x50=28
