slope formula.:
m = (y_2 - y_1) / (x_2 - x_1)
so you just need two points from whatever function you have
Or if you already have the function formula, then just the number of the first term (if your function is this: y=ax^2 + bx + c then the a is the slope)
Hope this helps!
All angles=40
therefore, internal angle= 140 degree
therefore, it has 5 sides

Answer:
0.02275
Step-by-step explanation:
We use the z score formula to solve for this
z-score is given as: z = (x-μ)/σ
where x is the raw score,
μ is the population mean
σ is the population standard deviation
In the above question:
mean of μ=500
a standard deviation of SD=100
raw score x = 700
Hence, z score = (700 - 500)/ 100
= 200/100
= 2
z score = 2
Using the z score table of normal distribution to find the Probability of z = 2
P( x = z)
= P(x = 700)
= P( z = 2)
= 0.97725
P(x>700) = 1 - P(x = 700)
= 1 - 0.97725
= 0.02275
Therefore, the probability of randomly selecting an individual from this population who has an SAT score greater than 700 is 0.02275
