B. Sec(0)= 5/13

C. Sec(0)= 5/12

D. Sec(0)= 13/5

Answer:

**Answer:**

D. sec(a) = 13/5

**Step-by-step explanation:**

if sin(a) = 12/13, then cos (a) = 5/13, because of 5-12-13 triangles

sec(a) = 1/cos(a)

1/(5/13) = 13/5

sec(a) = 13/5

2 x 9 is 18 x 10 is 180

45 - 8 is 37

180**divided by 37 is **4.9

so do 4-2 which is 2

The answer & explanation for this question is given in the attachment below.

The number of aces in the **first game **and the number of spades in the 5th game follow a Hypergeometric Distribution while the number of games receiving at least one ace can be modeled by a Binomial distribution. The event of all cards being from the same suit can be thought of as a Uniform distribution.

a) The number of aces you get in the first game follows a **Hypergeometric Distribution**. In such a distribution, you are drawing cards without replacement. The parameters are N=52 (the population size), K=4 (the number of success states in the population i.e., the number of aces in a deck), and n=13 (the number of draws).

b) The number of games in which you receive at least one ace can be modeled by a **Binomial distribution**. Each game you play (out of 50) is a single trial, with the probability of success (getting at least one ace) being the same for every trial. The parameters are n=50 (the number of trials/games) and p (the probability of getting at least one ace).

c) The likelihood of all your cards being from the same suit in a game is heavily reliant on chance, can be modeled as a *U*niform distribution given its rare occurrence. Essentially, the parameters would be minimum = 0 and maximum = 1. However, determining the parameters would require calculation of the specific probabilities, which is complex due to the nature of the game.

d) The number of spades you receive in the 5th game also follows a Hypergeometric distribution, similar to the situation in the first game. The parameters in this case are N=52, K=13 (number of spades in a deck), and n=13 (the number of drawn cards).

Pleas Solve quickly, thank you.

if..m/n = 5

then .. m = 5n

substitute 5n for m

(5n)² - 25n²

25n² - 25n² = 0

then .. m = 5n

substitute 5n for m

(5n)² - 25n²

25n² - 25n² = 0

**Answer:**

A.)359.2, B.)2.5 uf

**Step-by-step explanation:**

E / I = R

208 / 1.04 = 200 ohms

2*pi*f*L = Xl

6.28*400*.143 = 359.2 ohm

1 / (2*pi*f*Xc) = c

1 /(6.28*400*159.2) = 2.5 uf

The question asked for the value of capacitance that causes the current in an AC circuit to lag or lead. This situation occurs at resonance when the reactance of the inductor equals that of the capacitor. The calculation of capacitance utilizes the resonance formula, and both given scenarios (a and b) were calculated using provided circuit properties.

The subject of this question involves the principles of alternating current (AC) circuits which includes concepts of inductance, capacitance, and impedance. Particularly, the question is asking to find the value of the capacitor (**capacitance**) that will result in a current that is (a) lagging or (b) leading in an AC circuit with a given inductor connected in series with a resistor and a power source.

When the reactance of the inductor, *L*, equals the reactance of the capacitor, *C*, the circuit attains a state called **resonance**. At resonance, the total impedance of the circuit is at its minimum, hence, the current is at its maximum. This happens when the current leads or lags the voltage.

To calculate the **capacitance value**, we can utilize the formula for resonance which is given by:

f = 1/(2π√(LC))

Solving for C, we get:

**C = 1/(4π²f²L)**

**Substituting the given values (f = 400 Hz, L = 0.143 H) Into the formula, we calculate for C for both (a) and (b) scenarios.**
