Answer:
y=1.6x-8.4
Step-by-step explanation:
First, find the slope which is y 2 minus y 1 divided by x 2 minus x 1
Slope= 16/10 or 1.6
So now it is y=16/10x + b or y=1.6x+b
Now pick a random coordinate and substitute to find y intercept we can use the first one (29,38)
38=1.6(29)+b
y intercept = -8.4
Equation is y=1.6x - 8.4 or y=16/10x - 8.4
Hoped this helped :)
the answer is $32 you divide 160 by 5
If 10% are part-time workers, then 90% are full time
0.90(40) = 36 full time <==
Answer:
This isn't the best worded question but from what I understand a larger sample size decreases the margin of error. If he would like a more accurate answer a larger sample size of the viewers will give more accurate answers.

Answer:
- 8° per hour
Step-by-step explanation:
Given that:
Station A = - 6°
Station B = 2°
Rate of temperature change = x° / hour ; which is the same at both stations
Temperature at station A 3 hours after the recording is the same as the temperature in station B 4 hours after the recording ;
Temperature change in Station A:
-6 + 3x
Temperature change in station B:
2 + 4x
Temperature change in A = temperature change in B
-6 + 3x = 2 + 4x
Collect like terms
3x - 4x = 2 + 6
- x = 8
x = - 8
Hence, the rate of temperature change x in both stations is - 8° per hour
