Answer:
<u>This assume the equation is 35y = mx + c, and that r is meant to be x.</u>
Step-by-step explanation:
35y = mx + c
35y = -2(-7) - 3
35y = 14 - 3
35y = 11
y = (11/35)

The answer is to the question is 13
Answer:
Mean: 6.8
Median: 2
Mode: There is no mode of the data set
Step-by-step explanation:
Finding the mean: 5+8+2+9+10= 34 divided by the numbers of the data set which is 5= 6.8
Finding the median: The middle of the data set which is 2
Finding the mode: the most frequently occurring number which doesn't appear in this data set which means there is none.
Answer:
875 calories
Step-by-step explanation:
100%=2500calories
35% represents veggies
35*2500=87500÷100=875
875calories
Mixture problem.
Ratio of 20% : 50% acids
=50-39 : 39-20
=11:19
total volume
=400L
vol. of 20% acid=400*(11/(11+19)=400*(11/30)=146.667 L
vol. of 50% acid=400*(19/(11+19)=253.333 L
Alternatively, use c=volume of 20%, d=vol of 50%
then
0.2c+0.5d=400*0.39
Since c+d=400, we have
0.2c+0.5(400-c)=400*0.39=156
solve for c:
0.3c=44
c=146.667 and d=400-c=253.333 as before.
