Answer:

It is proportional

Step-by-step explanation:

To determine if its proportional/non-proportional is by using ratios

so go line by line

p pine and k oak

12 pine to 44 oak

18 pine to 66 oak

24 pine to 88 oak

30 pine to 110 oak

Start with the first line

p= pine per k= oak

so obviously not numbers but to help mind you it just means the numbers will be put as p/k (to make life simpler)

Or pine over oak

Second Line

12/44 which reduces down to 3/11

Third Line

18/66 which reduces down to 3/11

Fourth line

24/88 which reduces down to 3/11

Fifth line

30/110 which reduces down to 3/11

In order to be proportional the ratios all have to be equivalent to each other

Therefore,

3/11 = 3/11 = 3/11 = 3/11

So this is proportional

Korolek [52]

Answer:

0.509

Step-by-step explanation:

Given that a random sample of 1016 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?"

Of the 1016 adults surveyed, 517 indicated that televisions are a luxury they could do without.

To find out the point estimate of population proportion of adults in the country who believe that televisions are a luxury they could do without.

We find that point estimate is nothing but sample proportion

Sample proportion = favourably voters/total people surveyed

= $\frac{517}{1016} \\=0.5088\\=0.509$

As per the statement:

For her recipe:

She needs = $\frac{5}{7}$ of a cup of sugar.

It is also given that: 1/8 as much salt as sugar.

⇒ She needs salt for her recipe = $\frac{1}{8} \cdot \frac{5}{7} = \frac{5}{7 \cdot 8} = \frac{5}{56}$

Therefore, $\frac{5}{56}$ salt does she need for her recipe.
