expeople1 [14]

Answer: 40 out of 52 or reduced to 10 out of 13

Step-by-step explanation:

The probability of a heart is 13/52

You then have 39 cards left of 3 different suits

There will be 3 2's, 3 3's, 3 4's, 3 5's, 3 6's, 3 7's, 3 8's, 3 9's and 3 10's. (27 total)

27 + 13 = 40

40/52 or 10/13

(−14x^3y^3+4x^5 y6)÷(2x^4y^5)

valkas [14]

( - 14x^3)(y^3) + 4x^5y^6)/(2x^4y^5)

= 4x^5y^6 - 14x^3y^3/2x^4y^5

= 4x^2y^3 - 14/2xy^2

= 2x^2y^3 - 7/xy^2

Answer: 2x^2y^3 - 7/xy^2

Hope that helps!!!!

The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards (according to GolfWeek). Assume th

Usimov [2.4K]

Answer:

a) $f(x) = \frac{1}{25.9}$

b) 0.2046 = 20.46% probability the driving distance for one of these golfers is less than 290 yards

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

The probability density function of the uniform distribution is:

$f(x) = \frac{1}{b-a}$

The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards.

This means that $a = 284.7, b = 310.6$ .

a. Give a mathematical expression for the probability density function of driving distance.

$f(x) = \frac{1}{b-a} = \frac{1}{310.6-284.7} = \frac{1}{25.9}$

b. What is the probability the driving distance for one of these golfers is less than 290 yards?

$P(X < 290) = \frac{290 - 284.7}{310.6-284.7} = 0.2046$

0.2046 = 20.46% probability the driving distance for one of these golfers is less than 290 yards
