A perpetuity pays $50 per year and interest rates are 9 percent. How much would its value change if interest rates decreased to

PtichkaEL [24]

Answer:

We conclude that its value change for 277.8$.

Step-by-step explanation:

We know that a perpetuity pays $50 per year and interest rates are 9 percent. We calculate how much would its value change if interest rates decreased to 6 percent. We know that

9%=0.09

6%=0.06

We get

\frac{50}{0.09}=555.5

\frac{50}{0.06}=833.3

Therefore, we get 833.3-555.5=277.8

We conclude that its value change for 277.8$.

Please help! Thanks!: If a 95% confidence interval was being calculated using the following expression:

Roman55 [17]

The confidence interval can be calculated from the margin of error, and vice versa,

The margin of error of the confidence interval is 2.156

The confidence interval is given as:

$\mathbf{CI = 3.2 \pm 1.96 \cdot 1.1}$

The formula of confidence interval is:

$\mathbf{CI = \bar x\pm E}$

Where E represents the margin of error.

So, by comparison:

$\mathbf{E = 1.96 \cdot 1.1}$

Multiply

$\mathbf{E = 2.156}$

Hence, the margin of error of the confidence interval is 2.156

Question 4, plz help ( radius is 6.8)

Kisachek [45]

Answer:

A) 145.3 cm^2

Step-by-step explanation:

The formula for the area of a circle is A = π r^2

So to find the area we would plug the radius of 6.8 into the formula

Area = π (6.8)^2

Area = (3.14) (6.8)^2

Area = 145.27

Area = 145.3
