Answer:
the last statement is true
Step-by-step explanation:
the equation is in the form mx+c which means it is a stright line and will only cross the x axis once
You are given following <u>data</u>:
15 logs - 10 hours,
9 logs - x hours.
Use <u>proportion</u> to determine unknown <u>value</u> of x:
Then
Answer: 6 hours
The y-intercept is 50 and it tells how many chocolates he starts off with. The slop is -4 because that is how many chocolates he gives out each week. y=-4x+50
The line crosses the x -axis at point (9,0) and the y-axis at point (0,6).
If the equation of the line is then substitute the coordinates of the points into this equation:
1)
2)
Substitute the second equation into the first:
The equation of the line is
Answer: option C
I'll get you started:
mean = np = (500)(.56) = ?
standard deviation = √npq = √(500)(.56)(.44) = ?
Note: q = 1 - p
Finish the calculations.
To find z-score:
z = (x - mean)/sd
Note: x = 250
Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.
