The Greatest Problems on Campus

PSYCHO15rus [73]

Answer: D.) This is an example of inductive reasoning because a general conclusion is reached based on a specific example,

Step-by-step explanation: Inductive reasoning simply refers to making conclusion about a specific subject or topic from patterns or insights derived from related examples. In the scenario above, the conclusion reached encompasses the overall full time 4 years college student. However, this conclusion was inferred based on a specific example comprising of only a randomized sample of 1200 full time 4 years college students in 100 campuses. random. The example failed to incorporate every student, Hence, the conclusion is induced as the choice of a sample of students may not convey the choice or decision of all.

Deductive reasoning meanwhile follows that a generally established fact is used to make conclusion about a specific example.

alex41 [277]

Answer: The percent of the total was spent on veterinarian bills is 27.70% ( approx).

Step-by-step explanation:

Given, In 2011, Americans spent approximately $50.9 billion on their pets.

i.e. Total amount they spent on pets = $50.9 billion

Amount spent for veterinarian bills. = $14.1 billion was for veterinarian bills.

Then, the percent of the total was spent on veterinarian bills would be :

$\dfrac{\text{Amount spent for veterinarian bills. }}{\text{Total amount they spent on pets}}\times100\\\\=\dfrac{14.1}{50.9}\times100\\\\=27.7013752456\approx27.70\%$

Hence, the percent of the total was spent on veterinarian bills is 27.70% (approx).

ASAP PLEASE HELP An ostrich egg has a mass of 1.2 kg to the nearest tenth of a kilogram. Find the minimum and maximum possible m

katen-ka-za [31]

The maximum possible measurement is 1.25 Kg and the minimum possible measurement is 1.15 kg

<u>Solution:</u>

Given mass of an ostrich egg is 1.2 Kg

We have to find the minimum and maximum possible measurements to the nearest tenth of a kilogram

The greatest possible error in measurement nearest tenth of a kilogram, is a half a tenth of a kilogram which is:-

$\frac{1}{2} \times \frac{1}{10}=\frac{1}{20}$

Now, the maximum value will be equal to calculated amount plus the error in measurement of value .i.e.

$\text { Maximum value }=1.2+\frac{1}{20}=1.2+0.05=1.25$

Now, the minimum value will be equal to calculated amount minus the error in measurement of value .i.e.

$\text { Minimum value }=1.2-\frac{1}{20}=1.2-0.05=1.15$

Hence, maximum possible measurement is 1.25 Kg

And the minimum possible measurement is 1.15 kg
