In 42 of the 64 years from 1950 through 2014,the S& P 500 finished higher after the first five days of trading (in 2011 there was virtually no change). In 37 out of 42 years, the S&P 500 finished higher for the year. Is a good first week a good omen for the upcoming year? The following table gives the first-week and annual performance over this 64-year period.

S&P 500's Annual Performance
First week Higher Lower Total
Higher 37 5 42
Lower 11 11 22
Total 48 16 64

a) If a year is selected at random,
what is the probability that the S&P 500 finished lower for the year?

b) Given that the S&P finished lower after the first five days of trading,
what is the probability that it finished lower for the year?

c) Are the two events "first week performance" and "annual performance"
independent or dependent? Explain why.

Answers

9514 1404 393

Answer:

  10 square units

Step-by-step explanation:

The shape is a trapezoid with bases of 2 units and 8 units. Its height is 2 units, so its area is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(2 +8)(2) = 10

The area of the shape is 10 square units.

If a dozen dozen candies cost a half-a-dozen dimes a dozen, how much will a half-a-dozen dozen candies cost?

Answers

Answer:

74

Step-by-step explanation:

The cost of half-a-dozeon dozen candies for this case will be $3.6

How much a dozen consists of ?

A dozen of a thing means 12 of such thing is in consideration. If we say we have a dozen pencils, then twe mean we have 12 pencils.

For this case, it is given that:

Cost of a dozen dozen candies = half a dozen dimes a dozenCost of a half a dozen dozen candies = ? (to find)

A dozen contains 12 quantities.

A dozen dozen candies means 12 times 12 = 144 candies

half a dozen dimes dozen cost = (12/2) × 12 dimes = 72 dimes

That means:

144 candies cost 72 dimes.

Dividing both quantities by 144 to get price of 1 candy:

144/144 = 1 candy's price = 72/144 dimes = 0.5 dimes = 0.05 dollars (1 dime = 0.1 dollars)

Half a dozen times dozen candies = 72 candies

1 candy costs 0.05 dollars

72 candies cost [tex]72 \times 0.05 = 3.6[/tex] dollars.

Thus, the cost of half-a-dozeon dozen candies for this case will be $3.6

In the first one you are missing (a +7) so it's going to be 9(a +7) or when you factor that out it will be 9a 63

In the other one you are missing the (a +5) so it's going to be 7a(a + 5) or when you factor it out it will be 7a2 + 35a

Step-by-step explanation:

a2+ 9a + 20 = (a + 4) (a + 5)

a2 + 11a+ 28 = ( a + 7) ( a + 4 )

Suppose 10 tosses of a coin were all heads, and you switch to a new coin. What is the probability of tossing this new coin and getting another head?​

Answers

Answer:

50% or 1/2 Could be 100% but i think it is 50%

Step-by-step explanation:

Because Changing the coin will make no difference.

The probability of getting heads is same as the probability of tails which is [tex]\frac{1}{2}[/tex].

What is the probability?

The concept of probability is used to assign a numerical description to the likelihood of occurrence of an event.

Probability can be defined as the number of favorable outcomes divided by the total number of possible outcomes of an event.

Here given that,

The [tex]10[/tex] tosses of a coin were all heads, and you switch to a new coin.

So, the probability of getting all heads is [tex]2^{-n}[/tex]

And we have [tex]n=10[/tex],

Then, the probability of getting the heads is

[tex](^{n}C_k)(\frac{1}{2})^k(\frac{1}{2})^{n-k}=2^{-n}(^nC_k)[/tex]

Hence, the probability of getting heads is same as the probability of tails which is [tex]\frac{1}{2}[/tex].

Answers

Answer:

250000

Step-by-step explanation:

P=986.50(1-(1+.0249/12)^-(12)(30) Then divide the answer you get by (.0249/12)

Answer: 250,000

Step-by-step explanation:

We must apply the formula for P0, that is,

P0=986.50(1−(1+0.024912)−30⋅12)(0.024912),

which gives P0=$250,000 to the nearest $1.
