Answer:

         \large\boxed{\large\boxed{1/6}}

Explanation:

Some parts of the question are missing.

The complete question is:

<em>Alfred draws candles randomly from a pack containing 4 colored candles of the same shape and size. There are 2 red candles, 1 green candle, and 1 blue candle. He draws 1 candle and then draws another candle without replacing the first one. Find the probability of picking 1 red candle followed by another red candle, and show the equation used.</em>

<h2>Solution to the problem</h2>

The probability of picking 1 red candle followed by another red candle is the product of the probabilities of each event, taking into account that the second time the sample space is different (because there is no replacement).

<u>1. Probability of picking 1 red candle in the first drawing</u>:

  • Number of red candles / number of candles = 2/4 = 1/2

<u>2. Probability of picking 1 red candle in the second drawing</u>:

  • Number of red candles / number of candles = 1/3

<u>3. Probability of picking 1 red candle followed by another red candle</u>:

  • Equation: (1/2)×(1/3) = 1/6

Now that you have x² - 8x 16 = 9 16, apply the square root property to the equation.
vitfil [10]

The square root property to the equation will be (x – 4)² = 25. And the solutions will be the negative 1 and 9.

<h3>What is a quadratic equation?</h3>

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have

The equation is given below.

x² – 8x + 16 = 9 + 16

Then the equation can be written as

(x – 4)² = 25

x – 4 = ±5

x = 4 ± 5

x = -1, 9

You may need to use the appropriate technology to answer this question. A survey was conducted to determine whether hours of sle
Marina CMI [18]

Answer:

1) The null and alternative hypotheses.

H0: Hours of sleep per night is independent of age.

Ha: Hours of sleep per night is not independent of age.

Test Statistics χ²=4.009

The corresponding p-value for the test at χ²= 4.009 is 0.2604

Step-by-step explanation:

1) The null and alternative hypotheses.

H0: Hours of sleep per night is independent of age.

Ha: Hours of sleep per night is not independent of age.

2) The data is

                              ≤ 39           ≥ 40              Total

6 hours                    36               34                70

6.9-7 hours              60              57               117

7- 7.9 hours              79              77               156

<u>8 hours or more       65              92              157</u>

<u>Total                       240           260             500</u>

<u />

3) The expected values are computed as follows

260×70/500=36.4

240×117/500 =56.16

260×117/500 =60.84

240×156/500 =74.88

260×156/500 =81.12

240×157/500=75.36

260×157/500 =81.64

4) The squared distances are calculated as

{(36 - 33.6)^2}/{ 33.6} = 0.171

{(34 - 36.4)^2}{ 36.4} = 0.158

{(60 - 56.16)^2}/{ 56.16} = 0.263

{(57 - 60.84)^2}/{ 60.84} = 0.242

{(79 - 74.88)^2}/{ 74.88} = 0.227

{(77 - 81.12)^2}/{ 81.12} = 0.209

{(65 - 75.36)^2}/{ 75.36} = 1.424

{(92 - 81.64)^2}{ 81.64} = 1.315

5) The significance level is set at α=0.05 for df = (4 - 1) (2 - 1) =3

degrees of freedom.

6) The critical region for this test is χ² = χ² >7.815

7) Test Statistics

χ²=i=∑(O ij −Eij )2/Eij

=0.171+0.263+0.227+1.424+0.158+0.242+0.209+1.315

= 4.009

8) Conclusion

As the calculated value χ² =4.009 does not lie in the critical region ≤χ² =7.815, null hypothesis is not rejected.

Therefore, we conclude that there is not enough evidence to accept the alternate hypothesis , at the α=0.05 significance level.

The p-value for the test at χ²= 4.009 is 0.2604

Find an ordered pair x,y 4x-y=5
allochka39001 [22]

y=2X-5 and 4X-Y=7

Putting the value of Y in 2nd equation:

4x-2x+5=7

2x=7-5

2x=2

OR,x=2/2=1

 

putting the value of x in equation 1:

y=2x-5

y=2*1-5

y=2-5

y=-3

A bag of fertilizer covers 2000 square feet of lawn. What is the total number of bags of fertilizer that should be purchased to
andre [41]
Given that a bag of fertilizer covers an area of 2000 ft^2, the number of bags required to cover a lawn whose dimensions is 360 ft by 120 ft will be given by:
Number of bags=(area of lawn)/(area covered by 1 bag)×(number of bags)
thus
area of lawn:
A=length*width
A=360×120=43,200 ft²
Area covered by 1 bag=2000 ft²
Number of bags required for the lawn:
43200/2000
=21.6 bags
~22 bags
