Answer:

Her success (rate) chance is #(40-8)/40=32/40=4/5#

Explanation:

Therefore, she will make #4/5*60=48# kicks if her success (rate) chance remains the same.

Answer:

48

Explanation:

We can solve this in different ways:

1/

As direct proportion:

For direct proportion we have:

#y=propkx#

Where #k# is the constant of variation:

Form given information:

If she took 40 shots and missed 8 the she made 32.

Let #y=32# and #x=40#

#32=40k=>k=4/5#

So we have:

#y=4/5x#

For 60 shots, #x=60#

#y=4/5*60=color(blue)(48)#

So she will make 48 penalty kicks

As a percentage:

She had 32 successes out of 40, this as a percentage is:

#32/40 xx 100%=80%#

We now find #80%# of 60:

#80/100xx60=color(blue)(48)#

This also gives us the same result.
