The slope-intercept form of a line is:
Where m is the slope and y is the y-intercept:
To find q (y-intercept), substitute the coordinates of the point (9, -4) in the equation of the line and solve it as an equation:
-4=3(9)+q
-4=27+q
q=-27-4=-31
The equation of the line is: y=3x-31

Answer:
i think the answer is B
Step-by-step explanation:
formula is A^2+B^2=(A+B)(A-B)
160 + 35
All you have to do is subtract 195 with any number you like under 195 and then You have to numbers to add that equals 195 :-)
Answer: P(225 ≤ x ≤ 276) = 0.25
Step-by-step explanation:
Since the credit ratings for applicants are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = credit ratings of applicants
µ = mean
σ = standard deviation
From the information given,
µ = 200
σ = 50
The probability of a rating that is between 225 and 276 is expressed as
P(225 ≤ x ≤ 276)
For x = 225,
z = (225 - 200)/50 = 0.5
Looking at the normal distribution table, the probability corresponding to the z score is 0.69
For x = 276,
z = (276 - 200)/50 = 1.52
Looking at the normal distribution table, the probability corresponding to the z score is 0.94
Therefore,
P(225 ≤ x ≤ 276) = 0.94 - 0.69 = 0.25
