Kane rolls a dice and flips a coin at the same time. What is the probability he rolls a 2 or lower and the coin lands on heads?
lord [1]

Answer:

The probability he rolls a 2 or lower and the coin lands on heads is 16.66%.

Step-by-step explanation:

Since Kane rolls a dice and flips a coin at the same time, to determine what is the probability he rolls a 2 or lower and the coin lands on heads the following calculation must be performed:

Given = 6 sides = 2/6

Coin = 2 sides = 1/2

2/6 x 1/2 = X

0.333 x 0.5 = X

0.1666 = X

0.1666 x 100 = 16.66

Therefore, the probability he rolls a 2 or lower and the coin lands on heads is 16.66%.

Find an equation for the line that passes through the points (5, 2) and (-3,6).
RUDIKE [14]

Answer:

y = -1/2x + 6

Step-by-step explanation:

Find the slope

( 5 , 2) ( -3 , 6)

m =( y2 - y1 )/ ( x2 - x1)

x1 = 5

y1 = 2

x2 = -3

y2 = 6

m = ( 6 -2)/(-3 - 5)

m = 4/-8

m = - 1/2

Substitute m into the equation of a line

y = mx + c.

y = -1/2x + c

Substitute any of the two points given into the equation

Let's pick (2 ,5)

x = 2

y = 5

y = -1/2x + c

5 = -1/2(2) + c

5 = -1*2/2 + c

5 = -2/2 + c

5 = -1 + c

c = 5 + 1

c = 6

y = -1/2x + 6

The equation of the line is

y = -1/2x + 6
