Answer:
b = -1
Step-by-step explanation:
First plug in 4 for each x:
Then simplify by multiplying out what you can with 4:
After simplify further by combining like terms:
Then isolate b on one side by subtracting 4 from each side:
Finally isolate b further by dividing each side by 4 to get b alone and find the answer:
mean:20+17+10+31+25+18+12=132÷7=18.8
Media:10,12,17,18,20,25,31=
18÷1
= 18
mode=0
Range=31-10=21
Answer:
29 kg
Step-by-step explanation:
1 lb = 0.45359237 kg
65 lb * (0.45359237 kg)/lb = 29 kg
Your question is a little unclear. A guaranteed point that would be on the line would be (0,8) because, it is the y-intercept. There are tons of other points that would be on the line though. Try plotting it to see more examples.
A.) We know, sum of the complimentary angles is equal to 90.
So, Equation: 15 + x = 90
B.) Solving: 15 + x = 90
x = 90 - 15
x = 75
In short, Your Answer would be 75
Hope this helps!
