The required, Mmusi borrowed R3000 from Aggie as per the given conditions.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on loan.

Amount = Principal [1 + rate×time]

Let's call the amount Mmusi borrowed from Aggie "P".

After two years, he has to pay back
= P + P * 18% * 2
= P + 0.18 * P * 2
= P + 0.36P
= 1.36P

So if he has to pay back R4080, we can set up an equation to solve for P:

1.36P = 4080

To find P, we can divide both sides by 1.36:

P = 4080 / 1.36 = 3000

So Mmusi borrowed R3000 from Aggie.

The total cash flows would be -$97 + $36 + $98 = $37.

(a) The cash flows from your investment in the bond per $100 face value are as follows:

- At the time of purchase, you pay an amount less than $100 because the bond's yield to maturity is higher than the coupon rate. Let's assume you purchase the bond for $97.

- For each of the next four years, you receive a coupon payment of $9 (9% of $100 face value). So, you will receive $9 x 4 = $36 in total coupon payments.

- After receiving the fourth coupon payment, you sell the bond. Since the bond's yield to maturity was 7.77% at the time of purchase and sale, its market price would have changed. Let's assume you sell the bond for $98.

In summary, your cash flows per $100 face value would be:

- Initial cash outflow: -$97 (purchase price)

- Coupon payments: $9 x 4 = $36 (received over four years)

- Cash inflow from bond sale: +$98 (sale price)

Therefore, the total cash flows would be -$97 + $36 + $98 = $37.

Step-by-step explanation:

The formula for the volume of a pyramid is...

\(V=\frac{1}{3}Bh\)

B is the area of the base and h is the height from the middle of the pyramid to the top. Since we know both of these we can plug them in.

\(V=\frac{1}{3}(45*8)\)

\(V=\frac{1}{3}*360\)

\(V=\)

120

The volume for the pyramid is 120 yd^3.

Answer:

120 yards ^3

Step-by-step explanation:

To solve we need to know the formula.

The formula for the volume of a pyramid is  1/3 B * H

B= 45 and H = 8. We can sub those values in to the formula to solve.

= 1/3 45*8

= 1/3 360

=120

Since we multiplied yd^2 by yd, we get yd^3

So the answer is 120 yd^3

The dimensions of the box that minimize the surface area where x is the length of each side of the base and y is the height of the box are 8 cm x 8 cm x 2 cm.

To design a rectangular box with a square base and an open top, we need to determine the dimensions of the box that will minimize the surface area.

Let x be the length of each side of the base and y be the height of the box. The volume of the box must be 128 cm, so we can write the equation as x^2y=128.

Using the volume equation, we can solve for y in terms of x: y=128/x^2. Substituting this into the surface area equation, we get:

A=2x^2+4x(128/x^2)=2x^2+512/x.

We can find the critical points by taking the derivative and setting it to zero: A'(x)=4x-512/x^2=0.

Solving for x, we get x=8 cm. Substituting this into the volume equation, we get y=2 cm.

Therefore, the dimensions of the box that minimize the surface area are 8 cm x 8 cm x 2 cm.

Step-by-step explanation:

Yes, you did this correctly.

By subtracting the volume of the cylinder from the volume of the rectangular solid, you accurately acquired the volume of the remaining figure.

And yes, your calculations are correct.

To find the length of the curve given by r(t) = cos(7t) i + sin(7t) j + 7 ln(cos(t)) k, 0 ≤ t ≤ π/4, we need to use the formula for arc length:

L = ∫[a,b] √[dx/dt]^2 + [dy/dt]^2 + [dz/dt]^2 dt

In this case, we have:

dx/dt = -7 sin(7t)
dy/dt = 7 cos(7t)
dz/dt = -7 sin(t) / cos(t)

So,

[dx/dt]^2 + [dy/dt]^2 + [dz/dt]^2 = 49 sin^2(7t) + 49 cos^2(7t) + 49 sin^2(t) / cos^2(t)
= 49 [sin^2(7t) + cos^2(7t) + sin^2(t) / cos^2(t)]
= 49 [1 + sin^2(t) / cos^2(t)]

Now, using the identity sin^2(t) + cos^2(t) = 1, we can rewrite this as:

[dx/dt]^2 + [dy/dt]^2 + [dz/dt]^2 = 49 cos^2(t)

Therefore, the length of the curve is:

L = ∫[0,π/4] √[dx/dt]^2 + [dy/dt]^2 + [dz/dt]^2 dt
= ∫[0,π/4] 7 cos(t) dt
= 7 [sin(t)]|[0,π/4]
= 7 sin(π/4) - 7 sin(0)
= 7 (√2/2)
= 7√2/2

So the length of the curve is 7√2/2.

The probability of at most 1 person leaving the elevator on each floor when assuming that every person is equally likely to leave the elevator on any floor depends on the number of floors in the building and can be calculated using the binomial distribution formula.

Assuming that every person is equally likely to leave the elevator on any floor, the probability that on each floor at most 1 person leaves the elevator can be calculated using the binomial distribution.

Let's say there are n floors in the building. The probability of at most 1 person leaving the elevator on each floor is the probability that 0 or 1 person leaves the elevator on each floor. This can be calculated as follows:

P(at most 1 person leaves the elevator on each floor) = P(0 people leave on floor 1) x P(0 or 1 people leave on floor 2) x P(0 or 1 people leave on floor 3) x ... x P(0 or 1 people leave on floor n)

Now, since we are assuming that every person is equally likely to leave the elevator on any floor, the probability of 0 people leaving the elevator on any floor is (n-1)/n and the probability of 1 person leaving the elevator on any floor is 1/n. Therefore, we can calculate the probability of at most 1 person leaving the elevator on each floor as:

P(at most 1 person leaves the elevator on each floor) = (n-1)/n * (1/n + (n-1)/n)^(n-1)

Simplifying this expression, we get:

P(at most 1 person leaves the elevator on each floor) = (n-1)/n * (2/n)^(n-1)

For example, if there are 5 floors in the building, the probability of at most 1 person leaving the elevator on each floor is:

P(at most 1 person leaves the elevator on each floor) = 4/5 * (2/5)^4
P(at most 1 person leaves the elevator on each floor) = 0.08192

Therefore, the probability of at most 1 person leaving the elevator on each floor when assuming that every person is equally likely to leave the elevator on any floor depends on the number of floors in the building and can be calculated using the binomial distribution formula.

ra: Rate of calls to the center (inverse of ta, i.e., ra = 1/ta)

rθ: Rate of effective response (inverse of tθ, i.e., rθ = 1/tθ)

Given information:

Mean time between calls to the center (ta) = 6 minutes

Standard deviation of time between calls (∂a) = 4 minutes

Effective response time (tθ) = 11 minutes

Standard deviation of effective response time (∂θ) = 20 minutes

Using this information, we can determine the values of the parameters:

Experimental and quasi-experimental designs share similarities in terms of their focus on investigating cause-and-effect relationships. These designs both involve manipulating variables and observing their effects on an outcome of interest.

However, they differ in terms of the level of control the researcher has over the assignment of participants to groups. Experimental designs are characterized by the random assignment of participants to different groups or conditions. This randomization helps ensure that any observed differences between groups can be attributed to the manipulation of the independent variable. The researcher has control over the assignment process, allowing for stronger causal inferences. Quasi-experimental designs, on the other hand, lack the random assignment of participants to groups. This may be due to practical or ethical reasons. Instead, participants are assigned to groups based on pre-existing characteristics, such as age or location. While quasi-experimental designs still allow for the examination of cause-and-effect relationships, they are considered less rigorous than experimental designs due to the potential for confounding variables. In summary, experimental and quasi-experimental designs both aim to investigate cause-and-effect relationships. They differ primarily in the level of control the researcher has over participant assignment. Experimental designs use random assignment for greater control, while quasi-experimental designs rely on pre-existing characteristics.
