What three even numbers add up to 54

My name is Ann [436]

X = lowest
x+2 = middle
x+4 = largest

x + x+2 + x + 4 = 54

Combine like terms to get 3x + 6 = 54
Subtract 6 (both sides) -6 -6
 3x = 48
divide by 3 (both sides) 3 3

x = 16 (smallest even number) x+2 = 18 (middle even number and x+4 = 20 (largest even number) Add them up 16+18+ 20 and sure enough, you get 54

Suppose that the probability density function for the length x in feet of some type of fish caught by sport fishermen is given b

Firdavs [7]

Answer:

The probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is 0.4375.

Step-by-step explanation:

The probability density function or p.d.f. for the length x, in feet, of some type of fish caught by sport fishermen is :

$p(x) = \left \{{{(\frac{1}{4})\ ;\ 0\leq x\leq 4 } \atop{0\ ;\ otherwise} \right.$

The probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is:

$P(0.25\leq X\leq 2)=\int\limits^{0.25}_{2} {(\frac{1}{4})} \, dx \\=|(\frac{1}{4})x|^{2}_{0.25}\\=(\frac{1}{4})(2-0.25)\\=0.4375$

Thus, the probability that a fish caught by a fisherman is between 0.25 feet and 2 feet long is 0.4375.

20 - 6 = 14
14 • .075 = 1.05
14 + 1.05 = 15.05
20 - 15.05 = 4.95
