Brandon is running errands for his mother.
LiRa [457]

Answer:

As it is clear that adding 1/4 + 2/3 will bring 11/12. Therefore, Brandon is correct when he claims that he walks a total of  11/12  mile if he goes from his house to the library to the grocery store.

Step-by-step explanation:

As Brandon is

  • 1/4 mile from his house to the library
  • 2/3 mile from the library to the grocery store

Brandon claims that he walked a total of 11/12 mile if he goes from his house to the library to the grocery store

So, adding 1/4 + 2/3 would determine whether he is right or wrong.

Thus, considering the expression

\frac{1}{4}+\frac{2}{3}

\mathrm{Least\:Common\:Multiplier\:of\:}4,\:3:\quad 12

Adjust\:Fractions\:based\:on\:the\:LCM

\frac{1}{4}+\frac{2}{3}=\frac{3}{12}+\frac{8}{12}

         =\frac{3+8}{12}

         =\frac{11}{12}

As it is clear that adding 1/4 + 2/3 will bring 11/12. Therefore, Brandon is correct when he claims that he walks a total of  11/12  mile if he goes from his house to the library to the grocery store.

Reserve Problems Chapter 4 Section 5 Problem 2 A laptop company claims up to 10.1 hours of wireless web usage for its newest lap
Viktor [21]

Answer:

0.1151

Step-by-step explanation:

Given that a laptop company claims up to 10.1 hours of wireless web usage for its newest laptop battery life. However, reviews on this laptop shows many complaints about low battery life. A survey on battery life reported by customers shows that it follows a normal distribution with mean 9.5 hours and standard deviation 30 minutes.

If X is the battery life then X is N(9.5, 0.5)

(we convert into one unit for calculations purpose here hours)

a) the probability that the battery life is at least 10.1 hours

=P(X\geq 10.1)\\=P(Z\geq \frac{10.1-9.5}{0.5} )\\= P(Z\geq 1.2)\\=0.1151

we get the probability that the battery life is at least 10.1 hours is 0.1151
