Answer:
Step-by-step explanation:
Let's examine the individual things
A. x=0 --> y=3.0-5=-5 True
B. x=-1 --> y=3.(-1)-5=-8 False
C. x=5/3 -->y=3(5/3)-5=0 True
D. x=2 --> y=3.2-5=1 True
Answer is B.
You don't understand, you can ask me :)
Answer:
the answer would be 36,57,87 because it has to be equal to 180
and its an acute angle
Step-by-step explanation:
Step-by-step explanation: This simple confidence interval calculator uses a Z statistic and sample mean (M) to generate an interval estimate of a population mean (μ).
Note: You should only use this calculator if (a) your sample size is 30 or greater; and/or (b) you know the population standard deviation (σ), and use this instead of your sample's standard deviation (an unusual situation). If your data does not meet these requirements, consider using the t statistic to generate a confidence interval.
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
As you can see, to perform this calculation you need to know your sample mean, the number of items in your sample, and your sample's standard deviation (or population's standard deviation if your sample size is smaller than 30). (If you need to calculate mean and standard deviation from a set of raw scores, you can do so using our descriptive statistics tools.)
To convert temperatures in degrees Celsius to Fahrenheit multiply by 1.8 and add 32 so the paper has a typo you would multiply 25 x 1.8 = 45 + 32 = 77F so 25 C is 77 F but the way it says it we would all be dead because 25 x 8 = 200 + 32 = 232 F it would be to hot for life. So the correct answer is 77°F Hope this helps! ;D
Answer:
To get the slope (which we'll call n) of a line perpendicular to another line with slope (a/b), use
Then we just plug in the point we want to cross and solve for the constant.
Step-by-step explanation:
we see that m = 
so, 
now we have the equation
plugging in (6, -4) we get
This gives us our function
