Question

The probability of winning a prize in a local contest is 1 6. Find the actual odds against winning a prize A)1:5
B)1:6
C)5:1
D)6:1

Solution 1

**Answer:**

**Correct option is C i.e., 5:1.**

**Step-by-step explanation:**

The probability of winning a price is

The probability of losing is

The actual odd against winning will be:

**The ratio of losing to winning **which is:

=

**Thus the answer is: **

**C)5:1**

Solution 2

The probability of winning is 1/6

The probability of losing is 1-1/6=5/6

The odd against actual winning will be:

The ratio of winning to losing which is:

5:1

Thus the answer is:

C)5:1

The probability of losing is 1-1/6=5/6

The odd against actual winning will be:

The ratio of winning to losing which is:

5:1

Thus the answer is:

C)5:1

Question

Find the sum of the measures of the interior angles of a 52-gon.

Solution 1

We know that

52-gon means a polygon having 52 sides.Â

There is a formula for calculating the sum of interior angles of a polygon :Â

(2n-4) x 90Â° or (n-2) x 180Â° , where 'n' = number of sides.Â

Now, for sum of the interior angles of 52-gon:Â

(n-2) x 180Â°Â

=(52-2) x 180Â°Â

=50 x 180Â°Â

=9000Â°

**the answer is**

**the sum of the measures of the interior angles of a 52-gon is 9000****Â°**

Question

Suppose a1=2,an+1=12(an+2an). assuming an has a limit, find limnâ†’âˆžan= . hint: let a=limnâ†’âˆž. then, since an+1=12(an+2an), we have a=12(a+2a). now solve for a.

Solution 1

Looks like the sequence might be

Assume that . Then taking the limit of both sides, we have

But in order for the sequence to converge, only one of these values must be true. Since , each successive number will also be positive, so the limit must be .

Question

What is the tenth rule for A(n)=-9+5(n-1)

Solution 1

Given that the sequence follows the formula

A(n)=-9+5(n-1)

the tenth term will be given as follows:

From

A(n)=-9+5(n-1)

substitute n=10 in the equation we get:

A(10)=-9+5(10-1)

A(10)=-9+5(9)

A(10)=-9+45

A(10)=36

Answer: 36

A(n)=-9+5(n-1)

the tenth term will be given as follows:

From

A(n)=-9+5(n-1)

substitute n=10 in the equation we get:

A(10)=-9+5(10-1)

A(10)=-9+5(9)

A(10)=-9+45

A(10)=36

Answer: 36

Question

A ________ is a numerical quantity computed from the data of a sample and is used in reaching a decision on whether or not to reject the null hypothesis. a. significance level
b. critical value
c. test statistic
d. parameter

Solution 1

The answer for the completion exercise shown above is the second option (option b), which is:

**Â b. critical value.**

Â Therefore, you have that the text is: "A**critical value **is a numerical quantity computed from the data of a sample..."

Â This numeral quantity is used in statitics. Then, if the absolute value is greater that the quantity defined before, the null hypothesis must be rejected.

Â Therefore, you have that the text is: "A

Â This numeral quantity is used in statitics. Then, if the absolute value is greater that the quantity defined before, the null hypothesis must be rejected.

Question

Joey has a credit card that uses the previous balance method. The opening balance of one of his 30-day billing cycles was $0, but this was his balance for only the first 15 days of the billing cycle. He then made a purchase that increased his balance to $7200, and his balance stayed this amount for the remainder of the billing cycle. If his credit card's APR is 13%, how much was Joey charged in interest for the billing cycle?

Solution 1

Nope the answer would be $0 for apex

Question

A company issued 5-year, 7% bonds with a par value of $100,000. the market rate when the bonds were issued was 6.5%. the company received $102,105 cash for the bonds. using the effective interest method, the amount of recorded interest expense for the first semiannual interest period is: multiple choice $1,750.00. $3,318.41. $3,500.00. $6,573.90. $7,000.00.

Solution 1

The amount for the first **semiannual interest **period is: Â $3,318.41.

The **semi**-**annual **rate is the **simple **annual hobby quotation for compounding **twice **a year. Coupon charges on bonds paying hobby twice per yr are commonly expressed as **semi-annual prices. **This makes prices broadly comparable, even as also allowing the amounts of constant hobby coupons to be decided effortlessly.

**Semiannual **is an adjective that describes something that is paid, pronounced, published, or otherwise takes area twice every 12 months, normally as soon as every **six months.**

**expalnation;**

Time = 5 years

bond interest rate = 7%

parvalue = $100,00

market rate whwn the bond were issued = 6.5%

Amount received by the company = $102,105

$102,105-$100,000= $2105

$2105/10 =$210.5

1000*.07*.5= $3500

the amount for the first semiannual period = 3500- 210.5 = $3289.5

Therefore, the first **semiannual interest **period is: Â $3,318.41.

Solution 2

$102,105-$100,000= $2105

$2105/10 =$210.5

1000*.07*.5= $3500

3500- 210.5 = $3289.5

So in my estimation, it is $3,318.41

$2105/10 =$210.5

1000*.07*.5= $3500

3500- 210.5 = $3289.5

So in my estimation, it is $3,318.41

Question

A company's board of directors votes to declare a cash dividend of $1.50 per share of common stock. the company has 30,000 shares authorized, 25,000 issued, and 24,500 shares outstanding. the total amount of the cash dividend is:

Solution 1

The total amount of dividend will be:

Total=(Number of issued shares)*(dividend per share)

Number of issued shares=25000

dividend per share=$1.5

thus the total dividend will be:

1.5*25000

=$37500

Total=(Number of issued shares)*(dividend per share)

Number of issued shares=25000

dividend per share=$1.5

thus the total dividend will be:

1.5*25000

=$37500
