frutty [35]

Answer:

23/60

Step-by-step explanation:

All fractions of tiles, when summed up, need to be 1

Indian red is 1/4 of the tiles

Tuscan blue is 1/6 of the tiles

Fucalyptus is 1/5 of the tiles

Sand is X of the tiles (X is the fraction we want to know)

So, we can formulate the equation:

1/4 + 1/6 + 1/5 + X = 1

applying LCM, we have:

(15 + 10 + 12 + 60X) = 60

60X = 23

X = 23/60

Answer:

Option d is right

Step-by-step explanation:

Let X be the time spent on a treadmill in the health club

Given that research shows that on average, patrons spend an average of 42.5 minutes on the treadmill, with a standard deviation of 5.4 minutes

Also given that X is normal

the probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill.

$= P(30$

round off to two decimals tog et

the probability that randomly selected individual would spent between 30 and 40 minutes on the treadmill is 0.31

Hence option d is right
