add them both then you get the awnser if the four is not a negative. if the four is a negative use division.

A bridge hand is made up of 13 cards from a deck of 52. Find the probability that a hand chosen at random contains at least .
Tema [17]

Answer:

10%

Step-by-step explanation:

Since the question is not complete, I will be solving for probability of 3 9s

To solve this, we would be using the principle of combination, and thus

A deck of 52 hours has 4 nines, the probability that it contains at least 3 9s is mathematically represented by the equation.

P ( x ≥ 3 ) = ( 48 C 10 · 4 C 3 ) / ( 52 C 13 ) + ( 48 C 9 · 4 C 4 ) / ( 52 C 13 )

Remember I told us were going to be using the principle of combination. Well then

nCr = n!/r!(n - r)!

Now, applying the above stated formula to the equation, we have

48C10 = 48!/10!(38!)

4C3 = 4!/3!(1!)

52C13 = 52!/13!(39!)

48C9 = 48!/9!(39!)

4C4 = 4!/4!(0!)

Solving for each independently, we find that

= 0.0412 + 0.588 = 0.1

Can someone please help me? Thank you!
Volgvan

Answer:

Step-by-step explanation:

1) 5^{\frac{2}{3} } is in exponential form.

<u>Now, radical form is </u>\sqrt[3]{5^{2} }

2) 5^{\frac{1}{2} } is in exponential form.

<u>Radical form is </u>\sqrt{5}

3) 3^{\frac{2}{5} } is in exponential form.

<u> Radical form is </u>\sqrt[5]{3^{2} }

4) 3^{\frac{5}{2} } is in exponential form.

<u> Radical form is </u>\sqrt{3^{5} }

Serggg [28]

Answer:

<em>X=</em><em>-</em><em>1</em><em>8</em><em>/</em><em>7</em>

Step-by-step explanation:

-6x+18+2x=-18x-18

-4x+18= -18x-18

-4x+18x=-18-18

14x=-36

x=-36/14

x=-18/7

The number of pollinated flowers as a function of time in days can be represented by the function. f(x)
ratelena [41]

The average increase in the number of flowers pollinated per day between days 4 and 10 is <u>39</u>, given that the number of pollinated flowers as a function of time in days can be represented by the function f(x) = (3)^{\frac{x}{2} }.

In the question, we are asked for the average increase in the number of flowers pollinated per day between days 4 and 10, given that the number of pollinated flowers as a function of time in days can be represented by the function f(x) = (3)^{\frac{x}{2} }.

To find the average increase in the number of flowers pollinated per day between days 4 and 10, we use the formula {f(10) - f(4)}/{10 - 4}.

First, we find the value of the function f(x) = (3)^{\frac{x}{2} }, for f(10) and f(4).

f(x) = (3)^{\frac{x}{2} }\\\Rightarrow f(10) = (3)^{\frac{10}{2} }\\\Rightarrow f(10) = 3^5 = 243

f(x) = (3)^{\frac{x}{2} }\\\Rightarrow f(4) = (3)^{\frac{4}{2} }\\\Rightarrow f(10) = 3^2 = 9

Thus, the average increase

= {f(10) - f(4)}/{10 - 4},

= (243 - 9)/(10 - 4),

= 234/6

= 39.

Thus, the average increase in the number of flowers pollinated per day between days 4 and 10 is <u>39</u>, given that the number of pollinated flowers as a function of time in days can be represented by the function f(x) = (3)^{\frac{x}{2} }.
