Jayla's dog eats 0. 78 pounds of food a day. To the nearest pound, how much does her dog eat in 7 days?.

5.46 pounds

Step-by-step explanation:

0.78 x 7 = 5.46

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
