4. Assume that the chances of a basketball player hitting a 3-pointer shot is 0.4 and the probability of hitting a free-throw is 0.65. Assume that in a given game the player shoots 10 free throws and 10 3-point shots. Treat each shot is an independent trial and calculate the probability that the player will make exactly 3 3-pointers and 5-free throws.

Answers

Answer:

0.0334 = 3.34% probability that the player will make exactly 3 3-pointers and 5-free throws.

Step-by-step explanation:

For each 3-pointer shot, there are only two possible outcomes. Either the player makes it, or the player does not. The same is valid for free throws. This means that both the number of 3-pointers and free throws made are given by binomial distributions.

Since 3-pointers and free throws are independent, first we find the probability of making exactly 3 3-pointers out of 10, then the probability of making exactly 5 free throws out of 10, and then the probability that the player will make exactly 3 3-pointers and 5-free throws is the multiplication of these probabilities.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Probability of making 3 3-pointers out of 10:

The chances of a basketball player hitting a 3-pointer shot is 0.4, which means that [tex]p = 0.4[/tex]. So this is [tex]P(X = 3)[/tex] when [tex]n = 10[/tex].

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{10,3}.(0.4)^{3}.(0.6)^{7} = 0.21499[/tex]

Probability of making 5 free throws out of 10:

The probability of hitting a free-throw is 0.65, which means that [tex]p = 0.65[/tex]. The probability is [tex]P(X = 5)[/tex] when [tex]n = 10[/tex].

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 3) = C_{10,5}.(0.65)^{5}.(0.35)^{5} = 0.15357[/tex]

Calculate the probability that the player will make exactly 3 3-pointers and 5-free throws.

0.21499*0.15537 = 0.0334

0.0334 = 3.34% probability that the player will make exactly 3 3-pointers and 5-free throws.

Answer:

x-intercept: (-5, 0)y-intercept: (0, 4)perpendicular: 5x +4y = 0

Step-by-step explanation:

Each of the intercepts is found by setting the other variable to zero and solving for the intercept value.

x-intercept

  4x -5·0 +20 = 0

  x +20/4 = 0 . . . . . divide by the coefficient of x

  x = -5 . . . . . . . . . . add -5

The x-intercept point is (-5, 0).

__

y-intercept

  4·0 -5y +20 = 0

  y +20/-5 = 0 . . . . . divide by the coefficient of y

  y = 4 . . . . . . . . . . . add 4

The y-intercept point is (0, 4).

__

The perpendicular line is found by swapping the x- and y-coefficients, negating one of them. You want the leading coefficient positive, so the equation becomes ...

  5x +4y = (some constant)

The constant is chosen according to the point you want on the line. For a line through the origin, the constant is zero.

  5x +4y = 0 . . . . perpendicular line

Solve for n.

Answers

Answer:

n = 1/2 or .5

Step-by-step explanation:

4n + 3 = 10 -10n

14n = 7

n = 1/2 or .5

Hope this helps!

Answer:

n = -0.5

Step-by-step explanation:

4n + 3 = 5(2 - 2n)

First you multiply 2 and 2n by 5

4n + 3 = 10 - 10n

subtract 4n on both sides (meaning subtract 4n by itself on the left side of the equal sign and subtract 10n and 4n)

3 = 10 + 14n

Subtract 10 on both sides

-7 = 14n

Divide on both sides

Your answer should be n = -0.5 (or -0.5 = n)

If the radius of the base of the cone, r, is 8/3 units and the height, h, is 13 units, what is the volume of the cone?

Answers

Answer:

Step-by-step explanation:

r = 8/3 units

h = 13 units

Volume of cone = (1/3) πr²h

                           [tex]= \frac{1}{3}* 3.14 * \frac{8}{3}* \frac{8}{3}*13\\\\= 96.76 cubic units[/tex]

Question:-

If the radius of the base of the cone, r, is [tex] \frac{8}{3} [/tex] units and the height, h, is 13 units, what is the volume of the cone ?

Answer:-

Given:-

[tex] \bullet [/tex] Radius of the base of the cone (r) is [tex] \frac{8}{3} [/tex] units.

[tex] \bullet [/tex] Height (h) of the cone is 13 units.

To Find:-

Volume of the cone.

Solution:-

We know,

Formula of volume of cone is [tex] \frac{1}{3} [/tex] πr²h

So, volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × [tex] (\frac{8}{3})² [/tex] × 13

= [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × [tex] \frac{8}{3} [/tex] × [tex] \frac{8}{3} [/tex] × 13

= [tex] \frac{22 \: × \: 8 \: × \: 8 \: × \: 13}{3 \: × \: 7 \: × \: 3 \: × \: 3} [/tex]

= [tex] \frac{18304}{189} [/tex]

= 96.85 cubic units.

Volume of the cone is 96.85 cubic units. [Answer]

Landon has a points card for a movie theater. He receives 70 rewards points just for signing up. He earns 5.5 points for each visit to the movie theater. He needs 125 points for a free movie ticket. How many visits must Landon make to earn a free movie ticket?

Answers

Answer:

10 times

Step-by-step explanation:

125-70 bonus points =55 points left.

55 divided by 5.5 per visit = 10 times to get a free movie ticket.

To verify it is correct:

10 visits x 5.5 points each = 55 points total

55 + 70 bonus points = 125 for a free ticket.

Answer:

10

Step-by-step explanation:

Let x= number of visits

5.5x+70=

125

subtract -70 from 70 and 125

5.5x=  55

divide both sides by 5.5

x=10
