What is an equation of the line that passes through the points (6,8) and (-3,2)?

1. Use the slope formula
(6, 8) where x1 = 6 and y1 = 8
(-3, 2) where x2 = -3 and y2 = 2
Slope (m) = (y2-y1) / (x2-x1)
= (2-8) / (-3-6)
= -6 / -9
= 2/3

2. Use point-slope formula
y-y1=m(x-x1)
y-8=2/3(x-6)
y-8=2/3x -4

y = 2/3x + 4 :)

Consider randomly selecting a student at a large university. Let A be the event that the selected student has a Visa card, let B

wariber [46]

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

So to solve for x, you'll need to combine all the angles and equal it to 720, and from there we can solve.

$120+100+120+x+10+120+x=720$

Combine like terms to get $2x+470=720$

Subtract 470 on each side to get $2x=250$

Then just divide on each side and you'll get $x=125$

To find the value of the (x+10) angle, just substitute 125 for x and solve.

$125+10=135$
