What is the x-intercept of the line with the equation y=1/2x-3

1 answer:

7 0

A line crosses the x axis when y=0. the value of x at that point is the x-intercept

so substitute 0 for y and solve for x

0=1/2x-3

i like to multiply everything by the denominator of a fraction to clear fractions out

2(0)=2(1/2)x-2(3)

0=x-6
6=x

Artyom0805 [142]

Answer:

$E.G=\$2$

Step-by-step explanation:

Sample size 52 card

Pay for J or Q $=\$17$

Pay for King or Ace $=\$5$

Pay for others $=-\$2$

Therefore

Probability of drawing J or Q

$P(J&Q)=\frac{8}{52}$

Probability or drawing King or Ace

$P(K or A)=\frac{8}{52}$

Probability or drawing Other cards

$P(O)=\frac{36}{52}$

Therefore

Expected Gain is mathematically given as

$E.G=\sum_xP(x)$

$E.G=17*\frac{8}{52}+5*\frac{8}{52}+(-2)*\frac{36}{52}$

$E.G=\$2$
