Tito bought a rare album for $68.00 and later sold it for $76.00 what is the percent of increase , rounded to the nearest tenth?

Lostsunrise [7]

Answer:

Percent of increase=11.8%

Step-by-step explanation:

It is given in the question that Tito bought a rare album for $68.00 and later sold it for $76.00 .

So increase in price is the difference of selling price and the buying price. That is,

$76-68=$8$

And the percentage is

$\frac{8}{68}*100=11.8%$

And that's the required answer.

John davis, a manager of a supermarket, wants to estimate the proportion of customers who use food stamps at his store. he has n

8_murik_8 [283]

Answer:

1509

Step-by-step explanation:

We know that, formula for number of samples is,

$n= \frac{z^2 \times p \times q}{SE^2}$

When nothing is given, we take $p=0.5$ and we know that $q = 1-p=0.5$ .

SE = 0.03 (the true proportion should remain withing 3%)

Putting the values we get,

$n= \frac{(2.33)^2 \times 0.5 \times 0.5}{(0.03)^2}$

$n= \frac{5.4289 \times 0.5 \times 0.5}{0.03 \times 0.03} \approx 1509$

Therefore, the sample required to estimate the true proportion to within 3 percentage points is 1509.

A line segment has end points of ( 4,-4) and ( 0-5) what are the coordinates of the midpoint of this line segment?

Leni [432]

Use the Midpoint formula

Under a radical it would be

√ ( x↓2 - x↓1 ) ² + ( y↓2 - y↓1 ) ²

The down arrow is subscript -

So use the numbers from the two coordinates to plug in.

If you have any question comment :)
