ncludes only 111 jack, 111 queen, 111 king, and 111 ace.The only way Sarah can win is by flipping heads and then choosing either the jack or the queen.If XXX is a random variable that represents Sarah's outcome, drag the bars to graph the probability distribution for all possible values of XXX.

The probability distribution for all possible values of X are given in the discrete probability table ;

  • X : ____ winning ____ not winning

  • P(X) : ____ 0.25 ________ 0.75

<em>Fair coin = {H, T} </em>

<em>card = {J, Q, K, A} </em>

<u>Sample space</u> :

  • __ H ___ T
  • J | HJ __ TJ
  • Q| HQ __TQ
  • K| HK __ TK
  • A| HA __ TA

  • Total possible outcomes = sample space = 8

  • Winning selection = {HJ, HQ}

Probability of winning ; P(Winning) = 2/8 = 1/4 = 0.25

<u>Probability of not winning</u> ;

1 - P(wininng) = 1 - 1/4 = 3/4 = 0.75

X : ____ winning ____ not winning

P(X) : ____ 0.25 ________ 0.75

icang [17]

Answer:

No, unless the function decides to follow a different pattern. See more explanation below.

Step-by-step explanation:

He is wrong, the table doesn't tell us what happens at x=6.

It does tell us the following:

1) When x=-4, f(x)=6.

2) When x=-2, f(x)=3.

3) When x=0, f(x)=-1.

4) When x=2, f(x)=-4.

So maybe he got it the x and f(x) value switched in his brain.

Because according to 1) x=-4 when f(x)=6.

If the points keep having x increase while y decreases, then every x>2 will have a y less than -4 correspond to it.

The local pizza shop sells several special items.
Anna35 [415]

Answer:

Tax for Italian Salad=$0.20

Tax for Lasagna= $0.43

Tax for  Spaghetti =$0.21

Tax for Fettuccini Alfredo   =$0.36

Step-by-step explanation:

Hi, to answer this question we have to multiple the price of each item by the tax percentage in decimal form (divided by 100):

Italian Salad =$3.99  

  • Tax for Italian Salad= 3.99 x (5/100) = 3.99 x 0.05 =$0.20

Lasagna =$8.50  

  • Tax for Lasagna= 8.50 x (5/100) = 8.50 x 0.05 =$0.43

Spaghetti =$4.29  

  • Tax for Spaghetti = 4.29x (5/100) = 4.29 x 0.05 =$0.21

Fettuccini Alfredo =$7.17

  • Tax for Fettuccini Alfredo = 7.17 x (5/100) = 7.17 x 0.05 =$0.36

Feel free to ask for more if needed or if you did not understand something.

What is the cube root of -729a9b6
Harman [31]

<u>ANSWER</u>

\sqrt[3]{- 729{a}^{9}  {b}^{6} }  =  - 9 {a}^{3} {b}^{2}

<u>EXPLANATION</u>

We want to find the cube root of

- 729 {a}^{9}  {b}^{6}

We express this symbolically as:

\sqrt[3]{- 729 {a}^{9}  {b}^{6} }

The expression under the radical called the radicand.

We need to express this radical in exponential form using the property,

{x}^{ \frac{m}{n} }  =  \sqrt[n]{ {x}^{m} }

Applying this rule gives us:

\sqrt[3]{- 729 {a}^{9}  {b}^{6} }  =  ({- 729 {a}^{9}  {b}^{6}})^{ \frac{1}{3} }

\sqrt[3]{- 729{a}^{9}  {b}^{6} }  =  ({- {9}^{3}  {a}^{9}  {b}^{6}})^{ \frac{1}{3} }

Recall that

({a}^{m} )^{n} = {a}^{mn}

We apply this rule on the RHS to get,

\sqrt[3]{- 729{a}^{9}  {b}^{6} }  =  ({- {9}^{3 \times { \frac{1}{3} } }  {a}^{9 \times { \frac{1}{3} } }  {b}^{6 \times { \frac{1}{3} } }})

This simplifies to

\sqrt[3]{- 729{a}^{9}  {b}^{6} }  =  - 9 {a}^{3} {b}^{2}

Show all work to multiply (6+square root -64)(3-square root -16)
Hunter-Best [27]

Answer:

50

Step-by-step explanation:

- 8i = √-64

8i + 6

- -4i = -√-16

-4i + 3

[8i + 6][-4i + 3] → FOIL

>> -32i² + [24i - 24i] + 18

↑ ↑

-1 0

>>> 32 + 18 = 50

Information on Imaginary Numbers

√-1 = i

-1 = i²

-i = i³

1 = i⁴ [And every other exponent that is a multiple of 4; this cycle then repeats itself every time you go up one number at a time]
