Flip the coin below. Suppose that you win a prize if it comes up heads. What is p, the probability of success? What is 1 – p, the probability of failure?

Answers

Answer 1

Answer:

"p," the probability of success, is the chance of winning a prize.  This is equal to 50% (1/2).

1 - p, the probability of failure, is the chance of not winning or losing a prize.  This is equal to 50$ (1 - 0.5).

Step-by-step explanation:

When an outcome is obtained from two events, the probability of the outcome happening is 50% (1/2).

On the other hand, the probability of the intended outcome not happening is the difference between 1 and the probability of obtaining the outcome from the two events.  This is statistically expressed as 1 - p.

Answer 2

The probability of getting heads is 1/2 or 0.5 and the probability of failure is 0.5 or 50%.

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

Win a prize if it comes up heads.

p(getting heads) = win prize

Number of outcomes = {H, T}

Total number of outcomes = 2

Favourable outcomes = {H}

Number of favourable outcomes = 1

p(getting heads) = 1/2 = 0.5

The complement probability of the above event:

= 1 - p

= 1 - 0.5

= 0.5 or 50%

The above probability represents the chances not getting head or probability of failure.

Thus, the probability of getting heads is 1/2 or 0.5 and the probability of failure is 0.5 or 50%.

Answer:

B) y = 2x + 2

Step-by-step explanation:

Firstly, you have to know that parallel lines have congruent slopes. That means that the slope of this line will be 2.

Next, make a point slope form of the equation:

y - y1 = m(x - x1)

y - 2 = 2(x - 0)

y - 2 = 2x - 0

Now, we can make it into slope intercept form.

y - 2 = 2x

y = 2x + 2

If a variable has a distribution that is​ bell-shaped with mean 16 and standard deviation 6​, then according to the Empirical​ Rule, 99.7​% of the data will lie between which​ values? g

Answers

Answer:

99,7 % of all values will be in the interval ( -2 ; 34)

Step-by-step explanation:

Empirical Rule for the normal distribution with mean X,  implies that the intervals :

X ± σ             will contain  68 % of all values

X ± 2σ           will contain  95 % of all values

X ± 3σ           will contain  99,7 % of all values

Therefore in the interval    X  - 3σ   ;   X + 3σ

X - 3*6    =  X  -18  =  16 - 18 = -2

And

X + 3*6  = X + 18   = 16 + 18 = 34

99,7 % of all values will be in the interval ( -2 ; 34)

Consider the system:
y = 3x + 5
y = ax + b
What values for a and b make the system
inconsistent? What values for a and b make the
system consistent and dependent? Explain.

Answers

Answer:

Step-by-step explanation:

In this problem, we have the following linear equations:

y=3x+5

y=ax+b

We know that a linear equation is an equation for a line. In a system of linear equations, two or more equations work together.

1.  What values for a and b make the system inconsistent?

A system is inconsistent if and only if the lines are parallel in which case the system has no solution. This is illustrated in the first Figure bellow. Two lines are parallel if they share the same slope. So, the system is inconsistent for:

a=3

for any value of b

2. What values for a and b make the system consistent and dependent?

A system is consistent if and only if the lines are the same in which case the system has infinitely many solutions. This is illustrated in the second Figure bellow. So, the system is consistent and dependent for:

a=3 and b=5

Answer:

When a = 3 and b ≠ 5, the system will be inconsistent because the lines will be parallel. When a = 3 and b = 5, the system will be consistent and dependent because they represent the same line.

Lucy buys 7kg of nuts to sell.
She pays £10 for the nuts.
Lucy puts all the nuts into bags.
She puts 350g of nuts into each bag.
She then sells each bag of nuts for 75p.
Lucy sells all the bags of nuts.
Work out her percentage profit.

Answers

Answer:

Lucy's percentage profit = 33.33% based on Sales Value

and 50% based on Cost.

Step-by-step explanation:

a) Calculations:

7kg = 7,000g of nuts

Cost of 7,000g = £10

350g = 20 bags (7,000/350)

Sales value = £15 (20 x 75p)

Profit = Sales value minus Cost

Profit = £5 (£15 - £10)

Profit percentage based on sales = Profit/Sales x 100 = 5/15 x 100 = 33.33%

Profit percentage based on cost = Profit/Cost x 100 = 5/10 x 100 = 50%

b) Profit is the excess of sales over cost.  There are two ways to express it in percentages.  Profit can be expressed as a percentage of the cost (Markup).  It can also be expressed as the percentage of the sales value (Margin).

A. 44.79% B. 20.48% C. 48.84% D. 67.19%

Answers

Answer:

The percentage of employees with 8 or more years at the company that reported that email is their preferred method of communication is 30.48%. I suppose there was a small typing mistake in option B.

Step-by-step explanation:

The proportion is the number of desired outcomes divided by the number of total outcomes.

The percentage is the proportion multiplied by 100.

In this question:

210 employees with 8 of more year.

Of those, 64 have the email as their preferred method of communication.

64/210 = 0.3048

0.3048*100 = 30.48%

The percentage of employees with 8 or more years at the company that reported that email is their preferred method of communication is 30.48%. I suppose there was a small typing mistake in option B.

In this exercise we have to use the percentage knowledge to calculate the number of employees of the company over the years, in this way we find that this corresponds to:

The percentage of employees with 8 or more years at the company that reported that email is their preferred method of communication is 67,9%. Is D.

They are using the data informed in the text, we have:

210 employees with 8 of more year. Of those, 64 have the email as their preferred method of communication.

So doing the percentage calculation we have that;
