In a random sample of 8 people, the mean commute time to work was 35.5 minutes and the standard deviation was 7.4 minutes. A 90

konstantin123 [22]

Answer:

Margin of Error = 5.4088 ;

Confidence interval = (30.1 ; 40.9)

Interval estimate are almost the same

Step-by-step explanation:

Given that :

Population standard deviation, σ = 9.3

Sample size, n = 8

Xbar = 35.5

Confidence level = 90%

The confidence interval:

Xbar ± Margin of error

Margin of Error = Zcritical * σ/sqrt(n)

Zcritical at 90% = 1.645

Margin of Error = 1.645 * 9.3/sqrt(8) = 5.4088

Confidence interval :

Xbar ± Margin of error

35.5 ± 5.4088

Lower boundary = (35.5 - 5.4088) = 30.0912 = 30.1

Upper boundary = (35.5 + 5.4088) = 40.9088 = 40.9

(30.1 ; 40.9)

T distribution =. (30.5 ; 40.5)

Normal distribution = (30.1, 40.9)

Given figure is a <u>parallelogram</u>

Value of"x"

<h3><u>Solution</u></h3>

$m \angle \: A = m \angle \: C$

$2x + 35 = 5x - 22$

$\implies 2x - 5x = - 22 - 35 \div \\ \implies - 3x = - 57 \\ \\ \implies x = \frac{ - 57}{ - 3} \\ \\ \implies x = \cancel\frac{ - 57}{ - 3} \\ \\ \implies x = 19$

$\therefore \text{Option C= 19 is the correct answer}$

<h3>Hope this helps</h3>

JJM Corporation recently issued 10-year bonds at a price of $1,000. These bonds pay $60 in interest each six months. Their price

Doss [256]

Answer:

2,596

Step-by-step explanation:

Calculation to determine how many new bonds must JRJ issue to raise $2,000,000

Given,

Coupon rate = 8.0%

Face value = 1000

Year to maturity = 10

NPER = 20

First step is to calculate the PMT using this formula

PMT = Face value × Coupon rate / 2

Let plug in the formula

PMT=(1000 × 0.08) / 2

PMT= 80/2

PMT= 40

Second step is to calculate the Rate using this formula

Yield = 12%

Rate = Yield / 2

Let plug in the formula

Rate= 12% / 2

Rate= 6%

Third step is to calculate the net proceeds using this formula

Net proceeds= PV(rate, NPER, PMT, FV)

Let plug in the formula

Net proceeds= PV(6%, 20, 40, 1000)

Net proceeds= $770.60

Now let calculate how many new bonds must JRJ issue to raise $2,000,000

New bonds needed= $2,000,000 / 770.60

New bonds needed= 2,596 bonds

Therefore how many new bonds must JRJ issue to raise $2,000,000 will be 2,596 bonds
