Answer:

28 oz can is the better deal.

Step-by-step explanation:

In order to compare the two, we need to find the unit rate for each can. In this case, the unit rate will be in dollars per oz.

For the 28 oz can,

unit rate = $1.89 ÷ 28 = $0.675 / oz

For the 32 oz can

unit rate = $2.95 ÷ 32 = $0.922 / oz

comparing the unit rates, we can see that the unit rate for the 28 oz can is lower (i.e it costs less per oz for the 28 oz can compared to the 32 oz can)

Hence the 28 oz can is the better deal.

Are the graphs of the lines in the pair parallel? Explain.
jonny [76]
You need to convert the second equation to slope/intercept form. The first equation is in that form already. Then you can compare  slopes.

-6x + 8y = 14
8y = 6x + 14
y = (3/4)x + 14/8

SO THE SLOPE IS 3/4 which is the same as slope of equation 1

Therfore they are parallel.

Help please! make sure to tell me the answer and an explanation!
soldier1979 [14.2K]

Answer: 10

Step-by-step explanation:

So since this is all about perimeter you just got to add the values together. So lets use 12 as the denominator for every fraction. 1/4 is equal to 3/12 and 2/3 is equal to 8/12. So in conclusion 3/12 plus 8/12 and 1/12 will equal 1 in total. and then add up all the whole numbers 4 + 2 + 3 + 1 will get you 10. So 10 is your answer.

At a certain university, 42% of the students are women and 18% of the students are engineering majors. Of the engineers, 22% are
m_a_m_a [10]

Answer:

The probability that the selected person is a woman engineering major is 0.0396.

Step-by-step explanation:

The proportion of students at the university who are women is 0.42.

<em>P (W) = 0.42</em>

The proportion of students at the university who are engineering majors is 0.18.

<em>P (E) = 0.18</em>

The proportion of engineering majors that are women is 0.22.

<em>P (W|E) = 0.22</em>

The proportion of students at the university that are woman and engineering major is:

P (W|E)=\frac{P(W\cap E)}{P(E)} \\P(W\cap E)=P(W|E)\times P(E)\\= 0.18\times0.22\\=0.0396

Thus, the probability that the selected person is a woman engineering major is 0.0396.
