Iteru [2.4K]

Answer:

The correct option is 2.

Step-by-step explanation:

According to the the center-of-gravity technique, the coordinates of the center-of-gravity location are

(\frac{\sum x_iL_i}{\sum L_i},\frac{\sum y_iL_i}{\sum L_i})

Where ((x_i,y_i) represent the coordinates and L_i is demand.

We have to find the Y-coordinate of the center-of-gravity location.

The sum of product of demand and corresponding y coordinates is

\sum y_iL_i=65\times 2200+55\times 900+95\times 1300+200\times 1750+175\times 3100=1208500

The sum of demanded units is

\sum L_i=2200+900+1300+1750+3100=9250

The Y-coordinate of the center-of-gravity location is

y_0=\frac{\sum y_iL_i}{\sum L_i}

y_0=\frac{1208500}{9250}

y_0=130.6486

y_0\approx 131

The Y-coordinate of the center-of-gravity location is 131. Therefore the correct option is 2.

Integrate 2x/sqrt(1-x^2) dx from 0 to ½.
8_murik_8 [283]
A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator

61:3 odds pays out how much if you bet $25. I think $1550
Sonbull [250]

Answer:

$508.33

Step-by-step explanation:

If I bet $25 (And I win, of course), I will win:

If I win $61 per every $3 bet, then:

61/3 = x/25 ⇒ Solving for 'x':

61*25/3 = $508.33

Finally, if you bet $25 you will win $508.33.
