A5-column table has 4 rows. the first column has entries a, b, c, total. the second column is labeled x with entries 45, 20, 25, 90. the third column is labeled y with entries 30, 10, 35, 75. the fourth column is labeled z with entries 60, 25, 50, 135. the fifth column is labeled total with entries 135, 55 110, 300.
which statement is true about whether c and y are independent events?

c and y are independent events because p(c∣y) = p(y).
c and y are independent events because p(c∣y) = p(c).
c and y are not independent events because p(c∣y) ≠ p(y).
c and y are not independent events because p(c∣y) ≠ p(c).

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

they would have to work 32 hours.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
