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.

Alchen [17]

Answer:

36 ft

Step-by-step explanation:

The first step is to find the length of the hypotenuse of the newly formed right triangle. Using the Pythagorean theorem:

$x=\sqrt{10^2+24^2}=\sqrt{100+576}=\sqrt{676}=26$

Adding this to the 10 foot tall part of the tree that remains standing, you get an initial height of 26+10=36 feet. Hope this helps!

asambeis [7]

Answer:

All real numbers of x.

Step-by-step explanation:

5x+10=5(x+2) have the exact same equations on both sides.

5x+10=5x+10

If both are graphed, they will intersect each other for every value of x.
