Answer: the interest owed is $21

Step-by-step explanation:

The question is incomplete. The complete question is:

Sari Tagore obtains a $1000 loan to purchase a laser printer. Her interest rate is 7% ordinary interest for 108 days. What is the interest owed?

Solution:

When calculating ordinary interest, we assume that a year has 360 days. We would apply the formula for determining simple interest which is expressed as

I = PRT/100

Where

I represents interest paid on the loan

P represents principal or amount borrowed.

R represents interest rate

T represents duration in years

From the information given,

P = 1000

R = 7%

T = 108 days. Converting to years, it becomes 108/360

Therefore

I = (1000 × 7 × 108/360)/100

I = $21

Find the quotient of (11 ^ 18)/(11 ^ 3)

astraxan [27]

Answer:

The first choice, $11^{15}$ .

Step-by-step explanation:

The numerator, $11^{18}$ , is equivalent to eighteen " $11$ " multiplied together:

$11^{18} = \underbrace{11 \times 11 \times 11 \times 11 \times \cdots \times 11 \times 11}_{\text{$18$ in total}}$ .

On the other hand, the denominator, $11^{3}$ , is equivalent to three " $11$ " multiplied with one another:

$11^{3} = 11 \times 11 \times 11$ .

Dividing $11^{18}$ by $11^{3}$ would eliminate three " $11$ " from the numerator:

$\begin{aligned}& \frac{11^{18}}{11^{3}} \\ =\; & \frac{(11 \times 11 \times 11) \times \overbrace{11 \times \cdots \times 11}^{\text{$(18 - 3)$ in total}}}{(11 \times 11 \times 11)} \\ =\; & \overbrace{11 \times \cdots \times 11}^{\text{$15$ in total}} \\ =\; & 11^{15}\end{aligned}$ .

In general, dividing an expression by $y^{b}$ ( $y \ne 0$ ) is equivalent to multiplying that expression by $y^{-b}$ .

For example, in this question, dividing $11^{18}$ by $11^{3}$ would be equivalent to multiplying $11^{18}\!$ by $11^{-3}$ . In other words:

$\begin{aligned}& \frac{11^{18}}{11^{3}} \\ =\; & 11^{18} \times 11^{-3} \\ =\; & 11^{18 - 3} \\ =\; & 11^{15}\end{aligned}$ .

If p = .8 and n = 50, then we can conclude that the sampling distribution of pˆ is approximately a normal distribution

FrozenT [24]

Answer:

Yes we can conclude.

Step-by-step explanation:

The sampling distribution of $\hat{p}$ can be approximated as a Normal Distribution only if:

np and nq are both equal to or greater than 10. i.e.

np ≥ 10
nq ≥ 10

Both of these conditions must be met in order to approximate the sampling distribution of $\hat{p}$ as Normal Distribution.

From the given data:

n = 50

p = 0.80

q = 1 - p = 1 - 0.80 = 0.20

np = 50(0.80) = 40

nq = 50(0.20) = 10

This means the conditions that np and nq must be equal to or greater than 10 is being satisfied. So, we can conclude that the sampling distribution of pˆ is approximately a normal distribution
