Another easy way to remember the area of a square is s*s, or side times side.

if one side is 6 centimeters, then the other 3 are also 6 because it's a square.

so you can either do 6*6 = 36

or 6^2 = 36

I need help please find the volume of the shape!

nata0808 [166]

Answer:

D : 3456

Step-by-step explanation:

Use the formula 'volume of a cylinder' which is V = πr^2h

Since you know that the diameter is 20m and you need the radius, the radius is half the diameter, 10m. The height would be the length of the cylinder which is 11m.

Hence π10^2(11). If you put that in the calculator you get 3455.75, round it up and you 3456, answer D

There are 8,253 men and 10,327 women at a state university. If 43% of the men are in business and 27% of the women are in busine

fredd [130]

Answer:

68 students

Step-by-step explanation:

Number of men who major in business in the university= 0.43*8253=3548.79

Rounding off we have 3549 students

Number of women who major in business in the university= 0.27*10327=2788.29

Approximately 2789 students

Total students who major in Business= 3549+2789=6338 students

Total students in school= 8253+10327=18580

Probability of getting business major= 6338/18580

Out of 200 students, we expect

$\frac {6338}{18580} \times 200=68.22389666$

Approximately 68 students will be majoring in business

Look at the triangle show on the right. The Pythagorean Theorem states that the sum of the squares of the legs of a right triang

Vladimir [108]

Answer:

$cos^2\theta + sin^2\theta = 1$

Step-by-step explanation:

Given

$(\frac{b}{r})^2 + (\frac{a}{r})^2$

Required

Use the expression to prove a trigonometry identity

The given expression is not complete until it is written as:

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = (\frac{r}{r})^2$

Going by the Pythagoras theorem, we can assume the following.

a = Opposite
b = Adjacent
r = Hypothenuse

So, we have:

$Sin\theta = \frac{a}{r}$

$Cos\theta = \frac{b}{r}$

Having said that:

The expression can be further simplified as:

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = 1$

Substitute values for sin and cos

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = 1$ becomes

$cos^2\theta + sin^2\theta = 1$

A congested computer network has a 0.010 probability of losing a data packet and packet losses are independent events. a lost pa

Umnica [9.8K]

The probability of losing a data packet is 0.010.
Therefore the probability of successfully sending a data packet (not losing a data packet) is
p = 1 - 0.010 = 0.99

In 100 packet transmissions (independent events), the probability of success is
0.99¹⁰⁰ = 0.3660

The probability of losing a data packet is
1 - 0.366 = 0.6340

Answer:
The probability of resending a data packet is 0.6340
