The last time sierra played softball, she hit the ball 45% of the times she was at bat. based on this information, how many times will sierra hit the ball the next time she plays softball if she is at bat 20 times?

Number of times she will hit the ball  the next time she plays softball if she is at bat 20 times = 9 times

Step-by-step explanation:

Percentage of times Sierra hit the ball when she was at bat playing softball= 45%

So, we can find:

Number of times she will hit the ball  the next time she plays softball if she is at bat 20 times =

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

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.
