Task Scheduling would work if i use 0,15,30,45 in Minute in Cpanel "Cron Job"?

Hi, I've deployed Laravel in a shared hosting. It has some Scheduled tasks. But my hosting company (NameCheap) doesnt let me use * * * * * in cron job. Instead i had to use 0,15,30,45 in place of Minute. I've 2 tasks -

$schedule->call('App\Http\Controllers\ReedController@FromReed')->hourlyAt('15');
$schedule->call('App\Http\Controllers\CastController@FromCast')->dailyAt('17:0');

Above tasks will work?

Thank you
