The table shows two samples of fish from a pond. If 400 fish are in the pond, which proportion represents the average number of bass you would expect to live in the pond? (A)StartFraction 14 over 20 EndFraction = StartFraction x over 400 EndFraction
(B)StartFraction 7 over 20 EndFraction = StartFraction 400 over x EndFraction
(C)StartFraction 7 over 20 EndFraction = StartFraction x over 400 EndFraction
(D)StartFraction 20 over 40 EndFraction = StartFraction x over 400 EndFraction

is C

Step-by-step explanation:

because if u do the problem and the fraction it will give u that answer

monse856 is right

Step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
