Two samples were taken of fish caught on small lake and are shown in the table below. it is estimated that the small lake fish population is roughly 1,000 fish. what is the average number of brown trout in the lake? small lake fish sample sample 1 sample 2 rainbow trout 15 rainbow trout 11 brown trout 3 brown trout 1 largemouth bass 9 largemouth bass 11 43 80 160 333

80

Step-by-step explanation:

In the first sample, there were a total of

15+3+9 = 27 fish.

In the second sample, there were a total of

11+1+11 = 23 fish.

This is a total of 27+23 = 50 fish.

Out of those 50 fish, 3+1 = 4 were brown trout.  This is an experimental probability of 4/50.  

Multiplying this by the 1000 fish in the lake, we have

4/50(1000) = 4/50(1000/1) = 4000/50 = 80

The answer is B -80

Step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
