In a certain large lake 30% of the fish are thrown back because they are too small. Consider catching 525 fish from the lak in all your trips there. Assume that the fish you caught can be considered a random sample from the very large number of fish in the lake. Let Y = the number of fish that you throw back because they are too small. a) Find the probability you would throw back less than 140 fish: b) Use binomial distribution to find the mean and standard deviation for the number of fish thrown back: Mean: S. D.: c) Use a Normal Distribution apporximation to find the probability you would throw back more than 140 fish.

cells do need food. in a process known as cellular respiration, cells convert biochemical energy (oxygen as food) from nutrients into adenosine triphosphate (atp), and then release waste products.

hope this .. : d

ian gonna lie that is way to much

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
