Answer:

[tex]Probability = 0.30[/tex]

Step-by-step explanation:

Given

Represent Black with B and White with W

[tex]B = 14[/tex]

[tex]W = 6[/tex]

Required

Probability of the second selection being white

This means that: The first selection could be white or black but the second must be white.

This probability would be represented as thus:

[tex]Probability = (P(W)\ and\ P(W))\ or\ (P(B)\ and\ P(W))[/tex]

And it is calculated as:

[tex]Probability = (\frac{n(W)}{Total} * \frac{n(W)-1}{Total - 1}) + (\frac{n(B)}{Total} * \frac{n(W)}{Total - 1})[/tex]

Notice that, the second selection has total -1 has its denominator. This is so because, the first selection was made without replacement

So, the formula becomes

[tex]Probability = (\frac{6}{20} * \frac{6-1}{20- 1}) + (\frac{14}{20} * \frac{6}{20- 1})[/tex]

[tex]Probability = (\frac{6}{20} * \frac{5}{19}) + (\frac{14}{20} * \frac{6}{19})[/tex]

[tex]Probability = \frac{30}{380}+ \frac{84}{380}[/tex]

[tex]Probability = \frac{30 + 84}{380}[/tex]

[tex]Probability = \frac{114}{380}[/tex]

[tex]Probability = 0.30[/tex]

The probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball is 0.33.

Given :

The formula given below can be used in order to determine the probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball.

[tex]\rm P = \left(\dfrac{n(W)}{Total}\times \dfrac{n(W)-1}{Total-1}\right)+ \left(\dfrac{n(B)}{Total}\times \dfrac{n(W)}{Total-1}\right)[/tex]

Now, substitute the values of known terms in the above formula.

[tex]\rm P = \left(\dfrac{6}{20}\times \dfrac{6-1}{20-1}\right)+ \left(\dfrac{14}{20}\times \dfrac{6}{20-1}\right)[/tex]

Simplify the above expression.

[tex]\rm P = \dfrac{30}{380}+\dfrac{84}{380}[/tex]

[tex]\rm P =\dfrac{114}{380}[/tex]

P = 0.33

So, the probability that the second ball drawn is a white ball if the second ball is drawn without replacing the first ball is 0.33.

Therefore, the correct option is a).

193.21/0.87

= 222.08

So, the non-markup price was $222.08

Answer:

x = -4

Step-by-step explanation:

Equation of the Line

It can be written in the slope-intercept form as:

y = mx + b

Where m is the slope of the line and b is the y-intercept.

For horizontal lines, m=0. For slanted lines, m can have any real value.

Vertical lines have an infinite slope and the above equation cannot be used.

Vertical lines have a fixed value for x, thus the equation is:

x = h

If the vertical line goes through the point (-4,1), then its equation is:

x = -4

Answer:

The correct option is a. 65 to 89.

Step-by-step explanation:

According to the Empirical Rule in a normal distribution with mean µ and standard-deviation σ, nearly all the data will fall within 3 standard deviations of the mean. The empirical rule can be broken into three parts:

• 68% data falls within 1 standard deviation of the mean. That is P (µ-σ≤X≤ µ+σ) = 0.68.

• 95% data falls within 2 standard deviations of the mean. That is P (µ-2σ≤X≤ µ+2σ) = 0.95.

• 99.7% data falls within 3 standard deviations of the mean. That is P (µ-3σ≤X≤ µ+3σ) = 0.997.

The information provided is:

[tex]\mu=77\\\sigma = 6[/tex]

Use the Empirical rule to compute the middle 95% of the distribution as follows:

[tex]P(\mu-2\sigma\leq X\leq \mu+2\sigma)=0.95\\\\\mu-2\sigma=77-(2\times 6)=65\\\\\mu+2\sigma=77+(2\times 6)=89\\\\\Rightarrow P(65\leq X\leq 89)=0.95[/tex]

Thus, the correct option is a. 65 to 89.

Answer:

5.004493

Step-by-step explanation:

Answer:

2.27 kg is about 5 pounds.

Step-by-step explanation:

1 kilogram = 2.2 pounds

So, we have to multiply 2.2 by the amount of kilograms, which in this case, is 2.27.

2.27 x 2.2 = 4.994 or 5 when rounded to the nearest whole number.

Therefore, 2.27 kg = 5 lbs

Answer:

The answer would be x=7.5

Step-by-step explanation:

Answer:

x=7.5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2.45+5.5x−4.3x=1.3+0.7x

−2.45+5.5x+−4.3x=1.3+0.7x

Step 2: Combine Like Terms

(5.5x+−4.3x)+(−2.45)=0.7x+1.3

1.2x+−2.45=0.7x+1.3

1.2x−2.45=0.7x+1.3

Step 3: Subtract 0.7x from both sides.

1.2x−2.45−0.7x=0.7x+1.3−0.7x

0.5x−2.45=1.3

Step 4: Add 2.45 to both sides.

0.5x−2.45+2.45=1.3+2.45

0.5x=3.75

Step 5: Divide both sides by 0.5.

0.5x/0.5=3.75/0.5

so

x = 7.5

Answer:

4/5

Step-by-step explanation:

Okay, I'm pretty sure about this one! I might be wrong but:

If the number is prime and LESS than 13 (so it can't be 13 either), it's either 2, 3, 5, 7, or 11. Those are 5 numbers in all, and 4 of those are odd. So the fraction would be 4/5!

Answer:

There are 16 winning tickets and 64 losing tickets

Step-by-step explanation:

Total no of tickets in a bag = 80

The ratio of winning tickets to losing tickets is 2:8.

Let there are 2x winning tickets and 8x losing tickets.

ATQ,

2x+8x=80

10x=80

x = 8

Winning tickets = 2x = 2(8) = 16

Losing tickets = 8x = 8(8) = 64

Hence, there are 16 winning tickets and 64 losing tickets.
