In a family’s monthly budget, 2/5 of the income is spend on housing and 1/5 of the income is spent on food. How would you determ
aniked [119]

Answer:

2/5 is left

Step-by-step explanation:

Add the two you have so far together. 2/5+1/5=3/5

So 3/5 of your budget is used. 3/5 is a fraction, meaning that 5 is the whole.

Subtract 3 from 5 and you get 2. There are 2/5 left in the budget for everything else.

Consider the probability that no more than 28 out of 304 students will not graduate on time. Choose the best description of the
EleoNora [17]

Solution :

Here the probability that exactly 28 out of 304 students will not graduate on time. That is

P (x = 28)

By using the normal approximation of binomial probability,

$P(x=a) = P(a-1/2 \leq x \leq a+1/2)$

∴ $P(x=28) = P(28-1/2 \leq x \leq 28+1/2)$

                   $=P(27.5 \leq x \leq 28.5)$

That is the area between 27.5 and 28.5

Therefore, the correct option is (e). Area between 27.5 and 28.5

A local grocer cut his marketing budget by 57% last year. He spent only $650 on marketing this year and is happy with his decisi
jenyasd209 [6]

Answer:

Step-by-step explanation: The math portion of it would be as follows:

650 times 2, since it's been cut by more than half, which equals 1300.

650 times .07 = 45.5

695.5 times 2 = 1391.

Also, 1300 x .07 = 91.

Add them together, 1300 + 91 = 1391.

SO I think the correct answer is actually 1391, not 1511.63.
