The probability of being dealt a blackjack on the next hand is 4.8%. This is because there are only 4 cards that could make up a blackjack (an Ace and a 10-valued card), and there are only 82 cards left in the deck after two hands. Therefore, the probability of being dealt a blackjack is 4/82, or 4.8%.

The probability of being dealt a blackjack on the next hand is 4.8%. This is because a blackjack is made up of an Ace and a 10-valued card, so the probability of being dealt one is 4/82, or 4.8%. This is because after two hands, there are only 82 cards left in the deck. Of those 82 cards, there are only 4 that can make up a blackjack. Therefore, the probability of being dealt a blackjack is 4/82, or 4.8%. The fact that the deck is not being shuffled after each hand does not affect the probability, as the used cards are being put to the side and not used again until the deck is reshuffled.

Probability of blackjack = (number of cards that can make a blackjack / total number of cards remaining in the deck)

Probability of blackjack

= (4 / 82)

The two expressions are equivalent because they both represent the same concept: a number that is less than 3 but negative. In the first expression, -x, the negative sign in front of the x indicates that the value of the expression is the opposite of x. So if x is a positive number, then -x will be a negative number, and vice versa. In the second expression, x > -3, the greater than sign indicates that the value of x is greater than -3. Since we know that x is negative, this means that x is less than -3.

Therefore, both expressions represent the same thing: a number that is less than 3 but negative. This is why they are equivalent.

The estimate probability that there is at least one such accident during a given year, P(X≥1) is equals to the 0.0952..

We have, the probability that there is a significant accident in a nuclear power plant during one year, p = 0.01

Total nuclear plants in country , n = 100

we have to calculate probability that there is at least one such accident during a given year.

Using Binomial Probability distribution,

X ~ Bin( 100, 0.01)

P(X= x ) = ⁿCₓ(p)ˣ (1-p)⁽ⁿ⁻ˣ⁾

Thus, the probability that there is at least one such accident during a given year, P(X≥1)

= 1 - P(there is no such event, P(X= 0)

= 1 - P(X= r ) = 1 - ⁿCᵣpʳ(1-p )⁽ⁿ⁻ʳ⁾

where p is probability of success

r = 0 , n = 100, p = 0.001

plugging all known values in above formula,

P(X≥ 1) = 1 - ¹⁰⁰C₀ (0.001)⁰(1- 0.001)⁽¹⁰⁰⁻⁰⁾

= 1 - ¹⁰⁰C₀ (0.001)⁰(0.999)¹⁰⁰

= 1 - 1 ×1 ×0.904792

The expected value of X + 1 (Y - 1) can be calculated using the formula E(X + 1)(Y - 1) = E(X)E(Y) + E(X) - E(Y) + 1. Thus, the expected value of X + 1 (Y - 1) = 9/2 * 9/2 + 9/2 - 9/2 + 1 = 17. Therefore, the correct answer is d) 17.

The expected value of X + 1 (Y - 1) is a measure of the average value of the product of two independent random variables, X and Y. To calculate this expected value, we can use the formula E(X + 1)(Y - 1) = E(X)E(Y) + E(X) - E(Y) + 1. Since X and Y are independent random variables, we know that E(X) = E(Y) = 9/2. Plugging this value into the formula, we get E(X + 1)(Y - 1) = 9/2 * 9/2 + 9/2 - 9/2 + 1 = 17. This is the expected value of X + 1 (Y - 1). Therefore, the correct answer is d) 17.

The paper must be folded 43 times to get the thickness same as the distance from the earth to the moon.

Note that the function g is defined as [tex]g(n)=0.052^n.[/tex]

Let g(n) be the thickness that is g(n)=t.

Thus,

[tex]t & =0.05\left(2^n\right) \\\frac{t}{0.05} & =2^n \\\frac{100 t}{5} & =2^n \\20 t & =2^n\end{aligned}[/tex]

Take logarithms on both sides, thus

[tex]$$\begin{aligned}\log (20 t) & =\log \left(2^n\right) \\\log (20 t) & =n \log (2) \\n & =\frac{\log (20 t)}{\log (2)} \\n & =\log _2 20 t\end{aligned}$$[/tex]

Thus, [tex]g^{-1}=\log _2 20t[/tex]  is the required inverse function.

Answer:

The value of the path will be 1.

Here we need to evaluate the line integral of the given vector field F along the path C,

First, we need to express the path C as a function of a single variable t to use the integration formula

∫C F · dr = ∫a^b F(r(t)) · r'(t) dt

where  a and b are the limits of integration and r(t) is a parametrization of the path C

Here C consists of two straight line segments: one from (0, 0, 0) to (0, 0, 1) and one from (0, 0, 1) to (0, 1, 1).

expressing each line segment as a function of t by setting t equal to the length of the line segment we get

the parametrization r(t) = (0, 0, t), or the first line segment

by varying t from 0 to 1.

and

r(t) = (0, t, 1), for the second line segment which represents a line by varying t from 0 to 1.

Hence we will ultimately use the formula

∫C F · dr = ∫0^1 F(r(t)) · r'(t) dt + ∫0^1 F(r(t)) · r'(t) dt

= ∫tdt + ∫tdt

= t²

Step-by-step explanation:

Si on a une perfusion d'héparine 20 000 unités dans 500 ml de dextrose 5 % à un débit de 1 000 ml/heure, le débit en unités/heure d'héparine est calculé en divisant le nombre d'unités d'héparine (20 000) par le volume de la solution de dextrose (500 ml) pour obtenir la concentration en unités/ml d'héparine dans la solution (40 unités/ml). Ensuite, on multiplie la concentration par le débit de la solution (1 000 ml/heure) pour obtenir le nombre d'unités/heure d'héparine qui sont perfusées. 40 unités/ml x 1 000 ml/heure = 40 000 unités/heure, et puisque 1 heure = 60 minutes, le débit en unités/minute est de 40 000 unités/heure / 60 minutes/heure = 666,67 unités/minute. Enfin, on divise le débit en unités/minute par la concentration en unités/ml pour obtenir le débit en ml/minute, soit 666,67 unités/minute / 40 unités/ml = 16,67 ml/minute. Comme 1 litre = 1 000 ml, le débit en litres/heure est de 16,67 ml/minute x 60 minutes/heure = 1 000 ml/heure, et puisque la concentration d'héparine dans la solution est de 20 000 unités/500 ml = 40 unités/ml, le débit en unités/heure est de 1 000 ml/heure x 40 unités/ml = 40 000 unités/heure. Par conséquent, la réponse finale est de 40 000 unités/heure / 60 minutes/heure = 666,67 unités/minute / 40 unités/ml = 16,67 ml/minute x 60 minutes/heure = 1 000 ml/heure x 40 unités/ml = 40 000 unités/heure = 28 unités/heure.
