The temperature was in the range of 10-13 on 7 of the days.
Give it the weight of the middle of the range = 11.5 for 7 times = 80.5
The temperature was in the range of 14-17 on 9 of the days.
Give it the weight of the middle of the range = 15.5 for 9 times = 139.5
The temperature was in the range of 18-21 on 16 of the days.
Give it the weight of the middle of the range = 19.5 for 16 times = 312
The temperature was in the range of 22-25 on 22 of the days.
Give it the weight of the middle of the range = 23.5 for 22 times = 517
The temperature was in the range of 26-29 on 6 of the days.
Give it the weight of the middle of the range = 27.5 for 6 times = 165
Total weight for all ranges = (80.5 + 139.5 + 312 + 517 + 165) = 1,214
Total number of days = 60
Estimated mean temperature = (1,214) / (60) = <u>20.23°C </u>
The answer should be 8 because you cant divide 0, making the answer to that 0+12...which would then just be 12 making v=8 the answer
Answer:
There are 2-solutions.
Step-by-step explanation:
Answer:
(10q-p)/30=r
Step-by-step explanation:
p=10(q-3r)
distribute
p = 10*q - 10* 3r
p = 10q - 30r
subtract 10q from each side
p-10q = 10q-10q-30r
p-10q = -30r
divide by -30
(p-10q)/-30 = -30r/-30
-(p-10q)/30 =r
distribute
(-p+10q)/30 = r
i would rewrite to put the positive term 1st, put that is a personal choice ( my negative get lost in the parenthesis)
(10q-p)/30=r
Answer:
-1
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 10-5)/(-2-3)
=5/-5
= -1
