Hello,
I have a graphing calculator so this will be easy for me to answer and explain how to figure these out. Here we go!
1. Well on a Ti - 84 plus calculator it says graph then you put in thee equations for each and C and D are already incorrect cause they go straight up and B is incorrect because it is a straight line on the top going straight. In this case your looking for a line that goes through the dots. And the answer would be A) Y = 1/2x + 7.
2. B) Then umber of accidents were reduced by 0.67 per month for every additional driver in the program.
3. Key: Y means yes N means no. Plot A had 1 disease present and 2 not present. Plot B has 3 diseases present and 1 disease not present.
4. Category A had 36 groups in group 1. and Category B had 12 groups in group 1. Easy!
Please mark Brainliest!
Hope I Helped!
Have a fantastic Day!
The circumference of the circle is found using the formula C = 2 PI r
Circumference = 2 *PI * 15.5 = 31pi
The angle is 90 degrees, which is 1/4 of a complete circle ( 360 degrees).
The arc length would be 1/4 of the circumference:
Arc length = 31pi / 4 = 7.75PI
Answer:
300 days of work.
Step-by-step explanation:
He needs to work for 300 days for 2 dollars a day to get 600 dollars:
300 x 2 = 600
Lines 2 and four r perpendicular I think
What are both of their schedules? If they are completely different, then the next time they will leave together is 4:00 pm the next day
