The statement is totally false.

\neg P\lor\neg Q \equiv \neg(P \land Q) \not\equiv P\land Q

because (P and ¬P) is a contradiction.

C) 30, 60, 90 because right off the bat, the largest angle is 90 degrees and it is the ONLY answer in which it’s other 2 angles are summed up to equal to it. And the rest of the facts match up. 60 degrees is twice as 30

g Consider the experiment of a single roll of an honest die and a single toss of 3 fair coins. Let X be the value on the die and
klemol [59]

Answer:

The probability function of X and Y is

P(X = k, Y = 0)  = 1/48\\P(X = k, Y = 1) = 1/16\\P(X = k, Y = 2) = 1/16\\P(X = k, Y = 3) = 1/48

With k in {1,2,3,4,5,6}

Step-by-step explanation:

We can naturally assume that X and Y are independent. Because of that, P(X=a, Y=b) = P(X=a) * P(Y=b) for any a, b.

Note that, since the die is honest, then P(X=k) = 1/6 for any k in {1,2,3,4,5,6}. We can conclude as a consequence that P(X=k, Y=l) = P(Y=l)/6 for any k in {1,2,3,4,5,6}.

Y has a binomial distribution, with parameters n = 3, p = 1/2. Y has range {0,1,2,3}. Lets compute the probability mass function of Y:

P_Y(0) = {3 \choose 0} * 0.5^3 = 1/8

P_Y(1) = {3 \choose 1} * 0.5* 0.5^2 = 3/8

P_Y(2) = {3 \choose 2} * 0.5^2*0.5 = 3/8

P_Y(3) = {3 \choose 3} * 0.5^3 = 1/8

Thus, we can conclude that the joint probability function is given by the following formula

P(X = k, Y = 0) = 1/8 * 1/6 = 1/48\\P(X = k, Y = 1) = 3/8 * 1/6 = 1/16\\P(X = k, Y = 2) = 3/8 * 1/6 = 1/16\\P(X = k, Y = 3) = 1/8 * 1/6 = 1/48

For any k in {0,1,2,3,4,5,6}

What are the roots of this equation 2x^2+7x-3=0
Ludmilka [50]

Step-by-step explanation:

2x^2+7x-3=0

by doing splitting the middle term we get/ <u>using quadratic eq we get-</u>

Let's solve your equation step-by-step.

2x2+7x−3=0

For this equation: a=2, b=7, c=-3

2x2+7x+−3=0

Step 1: Use quadratic formula with a=2, b=7, c=-3.

x=

−b±√b2−4ac

2a

x=

−(7)±√(7)2−4(2)(−3)

2(2)

x= −7±√73 /4

x= −7 4 + 1 4 √73 or x= −7 4 + −1 4 √73

Answer:

x= −7 4 + 1 4 √73 or x= −7 4 + −1 4 √73

please mark me as the brainliest:)
