Lucy invested for 15 years at 2.8%, compounded annually and ended with an account balance of $2250. What was her initial deposit?

Answers

Answer:1244

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use the formula for calculating compound interest PN=P0(1+rk)Nk where N is the unknown, PN=2250, k=1, N=15, and r=0.028. Substitute the values into the formula and simplify.

2250=P(1+0.0281)1⋅15

2250=P(1.028)15

2250=P(1.5132...)

1486.91=P

Answer:

£0.60

Step-by-step explanation:

If each pack costs £1.59 and Nadia orders 15 packs,

then the total order before discount = 1.59 x 15 = £23.85

From the table given, we can see that for an order of £23.85 a 2.5% discount will be applied.

Divide £23.85 by 100 to get 1%:  £23.85 ÷ 100 = £0.2385

Now multiply by 2.5 to get 2.5%:  £0.2385 × 2.5 = £0.59625 = £0.60

Alternatively, the calculation in one expression is:

(1.59 × 15) × 0.025 = 0.59625

The total distance an ant crawls varies directly with the time in seconds. The ant crawls a total distance of 160 centimeters in 20 seconds.

What is the time in seconds the ant crawls when the total distance is 216 centimeters?


8 s

11 s

25 s

27 s

Answers

Answer:

27s

Step-by-step explanation:

Given data

total distance=160 cm

time taken =20seconds

We know that speed =distance/time

So let us solve for the speed of the ant

speed=160/20

speed= 8cm/s

Also when the distance is 216,and the ant uses the same speed,it will take the ant

time=distance/speed

time=216/8

time= 27seconds

A very large gardening business grows rose bushes for sale to garden stores around the world. The most popular colors are red, pink, and white. The business decides on 50% red roses, 30% pink, and 20% white. A gardener orders 10 rose bushes selected randomly from a huge field. Her primary interest is in pink roses. A good model for the number of bushes with pink roses is given by the binomial distribution. Probability calculations are quicker when using the Normal approximation to the binomial distribution. Which of the following is false

a. The approximation requires np 10 and n(1 â p) 10.
b. The sample size here is too small to use the Normal approximation to the binomial.
c. The approximation requires np 30.
d. The Normal approximation works better if the success probability p is close to p = 0.5.

Answers

Complete options are;

a. The approximation requires np > 10 and n(1 - p) > 10.

b. The sample size here is too small to use the Normal approximation to the binomial.

c. The approximation requires np > 30.

d. The Normal approximation works better if the success probability p is close to p = 0.5.

Answer:

Option C is false

Step-by-step explanation:

Looking at the options,

In normal approximation to the binomial,

n is the sample size,

p is the given probability.

q = 1 - p

Now, one of the conditions for using normal approximation to the binomial is that; np and nq or n(1 - p) must be greater than 10.

This means that option A is true because we require np or n(1 - p) to be greater than 10.

From Central limit theorem, the sample size needs to be more than 30 for us to use normal approximation. Our sample is 10. Thus, option B is true.

The approximation doesn't require np > 30. Rather it's the sample size that needs to be more than 30. Thus, option C is false.

Generally, when the value of p in a binomial is close to 0.5, the normal approximations will work better than when the value of p is closer to either 0 or 1. The reason is that: for p = 0.5, the binomial distribution will be symmetrical. Thus, option D is correct.

wo mechanics worked on a car. The first mechanic charged $95 per hour, and the second mechanic charged $75per hour. The mechanics worked for a combined total of 20 hours, and together they charged a total of $1800. How long did each mechanic work?

Answers

Answer:

he first one worked 15 hours, the second one worked 5 hours.

Step-by-step explanation:

First mechanic worked x hours, then second one worked 20 - x hours

First one charged $95*x, second one charged $75*(20-x)

Total charge = 95x + 75(20 - x) = 1800

95x + 1500 - 75x = 1800

20x = 300

x = 15, 20 - x = 5

So the first one worked 15 hours, the second one worked 5 hours.

Step-by-step explanation:

its the gray shaded area [(x+1)*(x+7)] minus the white area [(x-1)*(2x)]

AKA: [(x+1)*(x+7)] - [(x-1)*(2x)]

so first you foil to get both areas

gray region: (x+1)*(x+7) = x^2 + 8x + 7

white region: (x-1)*(2x) = 2x^2 - 2x

and then you subtract the white from the gray

First look for the fundamental solutions by solving the homogeneous version of the ODE:

[tex]y''+3y'=0[/tex]

The characteristic equation is

[tex]r^2+3r=r(r+3)=0[/tex]

with roots [tex]r=0[/tex] and [tex]r=-3[/tex], giving the two solutions [tex]C_1[/tex] and [tex]C_2e^{-3t}[/tex].

For the non-homogeneous version, you can exploit the superposition principle and consider one term from the right side at a time.

[tex]y''+3y'=2t^4[/tex]

Assume the ansatz solution,

[tex]{y_p}=at^5+bt^4+ct^3+dt^2+et[/tex]

[tex]\implies {y_p}'=5at^4+4bt^3+3ct^2+2dt+e[/tex]

[tex]\implies {y_p}''=20at^3+12bt^2+6ct+2d[/tex]

(You could include a constant term f here, but it would get absorbed by the first solution [tex]C_1[/tex] anyway.)

Substitute these into the ODE:

[tex](20at^3+12bt^2+6ct+2d)+3(5at^4+4bt^3+3ct^2+2dt+e)=2t^4[/tex]

[tex]15at^4+(20a+12b)t^3+(12b+9c)t^2+(6c+6d)t+(2d+e)=2t^4[/tex]

[tex]\implies\begin{cases}15a=2\\20a+12b=0\\12b+9c=0\\6c+6d=0\\2d+e=0\end{cases}\implies a=\dfrac2{15},b=-\dfrac29,c=\dfrac8{27},d=-\dfrac8{27},e=\dfrac{16}{81}[/tex]

[tex]y''+3y'=t^2e^{-3t}[/tex]

[tex]e^{-3t}[/tex] is already accounted for, so assume an ansatz of the form

[tex]y_p=(at^3+bt^2+ct)e^{-3t}[/tex]

[tex]\implies {y_p}'=(-3at^3+(3a-3b)t^2+(2b-3c)t+c)e^{-3t}[/tex]

[tex]\implies {y_p}''=(9at^3+(9b-18a)t^2+(9c-12b+6a)t+2b-6c)e^{-3t}[/tex]

Substitute into the ODE:

[tex](9at^3+(9b-18a)t^2+(9c-12b+6a)t+2b-6c)e^{-3t}+3(-3at^3+(3a-3b)t^2+(2b-3c)t+c)e^{-3t}=t^2e^{-3t}[/tex]

[tex]9at^3+(9b-18a)t^2+(9c-12b+6a)t+2b-6c-9at^3+(9a-9b)t^2+(6b-9c)t+3c=t^2[/tex]

[tex]-9at^2+(6a-6b)t+2b-3c=t^2[/tex]

[tex]\implies\begin{cases}-9a=1\\6a-6b=0\\2b-3c=0\end{cases}\implies a=-\dfrac19,b=-\dfrac19,c=-\dfrac2{27}[/tex]

[tex]y''+3y'=\sin(3t)[/tex]

Assume an ansatz solution

[tex]y_p=a\sin(3t)+b\cos(3t)[/tex]

[tex]\implies {y_p}'=3a\cos(3t)-3b\sin(3t)[/tex]

[tex]\implies {y_p}''=-9a\sin(3t)-9b\cos(3t)[/tex]

Substitute into the ODE:

[tex](-9a\sin(3t)-9b\cos(3t))+3(3a\cos(3t)-3b\sin(3t))=\sin(3t)[/tex]

[tex](-9a-9b)\sin(3t)+(9a-9b)\cos(3t)=\sin(3t)[/tex]

[tex]\implies\begin{cases}-9a-9b=1\\9a-9b=0\end{cases}\implies a=-\dfrac1{18},b=-\dfrac1{18}[/tex]

So, the general solution of the original ODE is

[tex]y(t)=\dfrac{54t^5 - 90t^4 + 120t^3 - 120t^2 + 80t}{405}\\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\dfrac{3t^3+3t^2+2t}{27}e^{-3t}-\dfrac{\sin(3t)+\cos(3t)}{18}[/tex]

In 2017, it was estimated that the average amount spent on winter holiday gifts in the United States was $906. Based on the estimate from the Waldfogel study, how much of this would be deadweight loss

Answers

Based on the estimate from the Waldfogel study, 10[tex]\%[/tex] of this would be a deadweight loss, i.e., [tex]\[/tex]90.6 would be the deadweight loss.

Deadweight loss means the economic inefficiency that takes place when the allotment of resources in a market isn't at the optimal position.

The study suggested that the average recipient's valuation of the gift received was approximately 90[tex]\%[/tex] of the actual purchase price of the gift.

This means that 10[tex]\%[/tex] of the value of the gift gets lost in between.

This loss of 10[tex]\%[/tex] in value constitutes the deadweight loss.

The average amount spent on gifts = $906

Percentage loss in value = 10[tex]\%[/tex] or 0.10

Calculation of the deadweight loss,

DWL = Average amount spent on gifts × Percentage loss in value

DWL = [tex]\[/tex]906 × 0.10

Thus, the deadweight loss would be [tex]\[/tex]90.6.
