ESP For several years, the General Social Survey asked subjects, “How often have you felt as though you were in touch with someo

ne when they were far away from you?” Of 3887 sampled subjects who had an opinion, 1407 said never and 2480 said at least once. The proportion who had at least one such experience was 2480/3887 = 0.638.

<h3>
How the find the proportion?</h3>

Given:

Total sample: 3887

No that had no opinion: 1407

No that had at least one experience: 2480

Perform the following division:
Radda [10]
Hey!


Alright, the first step to solving this division problem would be to convert the mixed fraction into a simple fraction.  To do that, we'll multiply the denominator by the whole number and then add that total to the numerator.

<em>Original Fraction :</em>
3 \frac{3}{4}

<em>New Fraction {Changed by Conversion} :</em>
\frac{15}{4}

Now that we've successfully done that we'll have to change the equation.

<em>Old Equation :</em>
\frac{15}{4} ÷ \frac{2}{8} = ?

<em>New Equation {Changed by Flipping the Second Fraction and the Symbol} :</em>
\frac{15}{4} · \frac{8}{2} = ?

Now we multiply straight across.

<em>Old Equation :</em>
\frac{15}{4} · \frac{8}{2} = ?

<em>Solved :</em>
\frac{120}{8}

Almost done!
Now we have to simplify the fraction.

<em>Old Fraction :</em>
\frac{120}{8}

<em>New Fraction {Changed by Simplification} :</em>
\frac{15}{1}

Now just convert it to a whole number by removing the fraction line and the number, and that's it!

<span><em>So, 3  \frac{3}{4} ÷ \frac{2}{8} equals</em></span>  15.

Hope this helps!

wolverine [178]

Answer:

The answer is 8 days.

Step-by-step explanation:

By applying the correct equations to Todd and Seth's balances for each day we end up with Todd and Seth having an equal balance in their accounts by day 8, alternatively, we can show that Todd and Seth have the same amount of money in their accounts by day 8 with this table

Day - Todd - Seth

1     -  95     - 130

2    -   90    - 120

3   -    85    -  110

I neeeeeeeeeedddddddddddd hhhhelpppppp

The step function is characteristic of the floor or ceiling functions, which map a real number to an integer.  There's clearly a factor of 2, indicated by two units of y for every one unit of x.

The open and filled circles indicate, for example, f(1)=2, f(1.01)=4.   That means we're rounding up, so we're using the ceiling function.

f(x) = 2 \lceil x \rceil

Answer: second choice
