I believe the answer is 1 because the line is negative and has a slope of 1/2 so -1/2 and it crosses at 8
me need slope and y intercept to get it in y=mx+b form (slope intercept)
Slope is the
difference in y / differences in x
differences in y = 6.5 -3 = 3.5
difference in x = 2 - 1 = 1
so slope is 3.5/1 or just 3.5
(now you can see the answer is c but lets check it by getting the y intercept too)
y intercept
this is when x is 0
the lowest x we see is 1 so if I go bacl to 0 in x the y must for back 3.5
3-3.5 is -0.5
so equation is y=3.5x -0.5 so the closest is c
200x 9, nine times two hundred,
Answer: 0.8531
Step-by-step explanation:
Let x be the random variable that represents the readings on scientific thermometers .
Given : The readings on scientific thermometers are normally distributed,
Population mean : 
Standard deviation : 
Z-score : 
Now, the z-value corresponding to -1.05 : 
P-value = 
Hence, the probability of the reading greater than -1.05 in degrees Celsius.= 0.8531
