laila [671]

Given that Marisa painted 1/2 of her bedroom in 3/4 of an hour.

we know that there are 2 halfs in a bedroom.

Each half will take 3/4 hours

so total time to paint entire bedroom

$=\frac{3}{4}+\frac{3}{4}$

$=\frac{3+3}{4}$

$=\frac{6}{4}$

$=\frac{3}{2}$

Hence final answer is 3/2 hours or you can say 1.5 hours.

aleksklad [387]

Answer: 2.4

Step-by-step explanation:

Given : A large disaster cleaning company estimates that 30 percent of the jobs it bids on are finished within the bid time.

i..e The proportion of the jobs it bids on are finished within the bid time: p = 30%= 0.30

Sample size of jobs that it has contracted : n= 8

Then , the mean number of jobs completed within the bid time : $\mu=np$

$= 8\times0.30=2.4$

Hence, the mean number of jobs completed within the bid time is 2.4 .
