Answer:
![\sf B) \ y=-\dfrac{1}{5}x-4](https://tex.z-dn.net/?f=%5Csf%20B%29%20%5C%20y%3D-%5Cdfrac%7B1%7D%7B5%7Dx-4)
Explanation:
Equation: y = mx + b [where "m" is slope, "b" is y-intercept]
The y-intercept (b) is -4
![\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points](https://tex.z-dn.net/?f=%5Csf%20slope%3A%20%5Cdfrac%7By_2%20-%20y_1%7D%7Bx_2-%20x_1%7D%20%5C%20%5C%20%20where%20%5C%20%28x_1%20%2C%20%5C%20y_1%29%2C%20%28%20x_2%20%2C%20%5C%20y_2%29%20%5C%20are%20%5C%20points)
Here take two points: (0, -4), (5, -5)
![\sf slope \ (m) : \dfrac{-5-(-4)}{5-0} = -\dfrac{1}{5}](https://tex.z-dn.net/?f=%5Csf%20slope%20%5C%20%28m%29%20%3A%20%5Cdfrac%7B-5-%28-4%29%7D%7B5-0%7D%20%20%3D%20%20-%5Cdfrac%7B1%7D%7B5%7D)
![\sf Hence \ equation : y = -\dfrac{1}{5} x -4](https://tex.z-dn.net/?f=%5Csf%20Hence%20%20%20%5C%20equation%20%3A%20%20y%20%3D%20-%5Cdfrac%7B1%7D%7B5%7D%20x%20-4)
14/12 is 1.166666666666667 as in a fraction its 7/6
Answer:
I this is the B ,I hope hepl you
Answer:
a. 0.76
b. 0.23
c. 0.5
d. p(B/A) is the probability that given that a student has a visa card, they also have a master card
p(A/B) is the probability that given a student has a master card, they also have a visa card
e. 0.35
f. 0.31
Step-by-step explanation:
a. p(AUBUC)= P(A)+P(B)+P(C)-P(AnB)-P(AnC)-P(BnC)+P(AnBnC)
=0.6+0.4+0.2-0.3-0.11-0.1+0.07= 0.76
b. P(AnBnC')= P(AnB)-P(AnBnC)
=0.3-0.07= 0.23
c. P(B/A)= P(AnB)/P(A)
=0.3/O.6= 0.5
e. P((AnB)/C))= P((AnB)nC)/P(C)
=P(AnBnC)/P(C)
=0.07/0.2= 0.35
f. P((AUB)/C)= P((AUB)nC)/P(C)
=(P(AnC) U P(BnC))/P(C)
=(0.11+0.1)/0.2
=0.21/0.2 = 0.31
Answer:
A
Step-by-step explanation:
This is because each x coordinate is mapped to a y coordinate.
