Answer:

$2,391.20

Step-by-step explanation:

A= P (1+r/n)^nt

Where:

A = is the amount of money accumulated after n years, including interest.

P = is the principal (the initial amount you borrow or deposit)

r = is the annual rate of interest (percentage)

t = is the number of years the amount is deposited or borrowed for.

n = number of times interest is compounded per year

A= $2,000 (1+0.06/4)^4*3

 =  $2,000 (1+0.015)^12

=  $2,000 (1.015)^12

=  $2,000 (1.1956)

= $2,391.20

Answer:

The probability is 0.9545

Step-by-step explanation:

We start by using z-scores here

Mathematically;

z-score = (x-mean)/SD

mean = 24 ounces

SD = 3 ounces

For 18, we have

z-score = (18-24)/3 = -6/3 = -2

For 30, we have

z-score = (30-24)/3 = 6/3 = 2

So the probability we want to calculate is;

P( -2 < x < 2)

We can use the standard normal distribution table for this

From the standard normal distribution table;

P(-2 < x < 2) = 0.9545

Given:

The probability of drawing a blue cube from a hat is 80%.

To find:

The probability of drawing 4 blue cubes in a row.

Solution:

Let E be the event of drawing a blue cube from a hat.

[tex]P(E)=80\%[/tex]

[tex]P(E)=\dfrac{80}{100}[/tex]

[tex]P(E)=0.8[/tex]

We need to find the probability of drawing 4 blue cubes in a row.

Let as consider each cube is replaced after being drawn. So, that probability of drawing a blue cube from a hat remains same.

Probability of drawing 4 blue cubes in a row is

[tex]P(E)\times P(E)\times P(E)\times P(E)=(P(E))^4[/tex]

                                                          [tex]=(0.8)^4[/tex]

                                                          [tex]=0.4096[/tex]

Therefore, the required probability is 0.4096.

Answer: 0.12 per minute

Step-by-step explanation: I actually had to reread this one a couple times, as the setup is a bit confusing. Here's how I would solve it personally:

1. Since it's leaking 2ml per second, and there are 60 seconds in a minute, multiply 2ml times 60 seconds to get 120ml every minute.

2. 1ml equals 0.001 liters, so multiply 120ml by 0.001 to find out how many liters that is. 120(0.001)=0.12.

Hope this helps,

Answer:

4. is x = 9

but I don't know about 5. sorry.

Step-by-step explanation:

5x + 3 = 48

-3. -3

5x = 45

5. 5

x = 9

5(9) + 3 = 48

48 = 48

Answer:

0.288

Step-by-step explanation:

Given that :

Correlation (R) = 0.48

Slope of linear model which predicts Lifespan from years of education (m) = 0.8

To determine the value of slope of the model which predicts years of eductauoon from lifespan:

The square of the regression Coefficient is multiplied by the inverse of the slope of linear model which predicts Lifespan from years of education

Hence,

(R² * 1/m)

0.48² * 1/0.8

0.2304 * 1.25

= 0.288

Answer: B.

Step-by-step explanation:

Let x = Number of hours the robot is performing a test run.

Given: Constant speed = 4 miles per hour

Average test run = 3 miles

Since Distance = speed x time

As per given,

(Constant speed) ( Number of hours) -(average test run) = (distance varies)

|4x-3|=1.5

Hence, the correct option is B.

Answer:

yo i think the answer is y=5 but not sure bro.

Step-by-step explanation:

Answer:

A = - 0.3 and B = - 0.1.

Step-by-step explanation:

y(x) = A sinx + B cosx

y'(x) = A cosx - B sinx

y"(x) = -A sinx - B cos x

So, substituting we have:

y" + y' - 2y = -A sinx - B cos x + A cosx - B sinx - 2(A  sinx + B cosx)

=    -3A sin x - B sinx + A cosx  - 3B cos x = sinx

sin x (-3A - B) + cos x(A - 3B) = sin x

Since this is an identity then we equate coefficients:

-3A - B =  1

A - 3B = 0

Solving these we get A = - 0.3 and B = - 0.1.

Step-by-step explanation:

$5.25*6/100=Your tax

Answer:

$ 87.50

Step-by-step explanation:

First, identify what is given from the problem:

Tax Amount = $5.25

Tax Rate = 6%

Original Cost  = ?

Then let us state the original formula stated from the problem.

Tax Amount = (Original Cost)(Percent)

Since the Percent in our equation is the Tax Rate, let us substitute it to avoid confusion.

Tax Amount = (Original Cost)(Tax Rate)

The Original cost is the only unknown in this equation as stated from the given. Now we need to arrange first the equation so that the unknown should be on the left side.

(Original Cost)(Tax Rate) = Tax Amount  

To remove the Tax Rate to be multiplied to the Original Cost, let us divide both side by the same Tax Rate. This holds true to all as long as what you did on the left side of the equation should be done on the right side of the equation.

(Original Cost)(Tax Rate) / (Tax Rate) = (Tax Amount) / (Tax Rate)

This will cancel the Tax Rate on the left side of the equation to yield to a new formula for the Original Cost.

Original Cost = (Tax Amount) / (Tax Rate)

We can then substitute the values to solve the problem

Original Cost = $ 5.25 / 0.06

Original Cost = $ 87.50

Therefore the original price before tax is $ 87.50

Answer:

f(1)= 1

Step-by-step explanation:

So assuming you're doing basic functions, f(x) just means "function of x".

This means that x is your input. So once you plug in the x value, you will see that when the x value of your function is 1, the y value is 1 as well.

This will be marked brainliest if correct ok?

Answer:

The answer is below

Step-by-step explanation:

The time between arrivals of taxis at a busy intersection is exponentially distributed with a mean of 10 minutes. (a) What is the probability that you wait longer than one hour for a taxi? (b) Suppose that you have already been waiting for one hour for a taxi. What is the probability that one arrives within the next 10 minutes? (c) Determine x such that the probability that you wait more than x minutes is 0.10. (d) Determine x such that the probability that you wait less than x minutes is 0.90.

Answer:

A continuous variable is has a probability distribution function as:

[tex]f(x)=\lambda e^{-\lambda x}[/tex]

A continuous variable is has a cumulative distribution function as:

[tex]F(x)=1- e^{-\lambda x}[/tex]

Given mean  = 10 minutes

[tex]mean=\frac{1}{\lambda}\\ \\10=\frac{1}{\lambda}\\\\\lambda=\frac{1}{10}[/tex]

a) P(X > 1 hour) = P(X > 60 minutes) = 1 - F(60) = [tex]1-[1-e^{-60*0.1}]=0.0025[/tex]

b) P(X < 70 | x > 60) = P(X < 10) = [tex]1-e^{-10*0.1}=0.6321[/tex]

c) 0.1 = P(X > x)

0.1 = 1 - F(x)

[tex]0.1=1-[1-e^{-0.1*x}\\\\0.1=e^{-0.1x}\\\\ln(0.1)=-0.1x\\\\-2.3=-0.1x\\\\x=23\ minutes[/tex]

d) 0.9 = P(X < x)

0.9 = F(x)

[tex]0.9=1-e^{-0.1*x}\\\\e^{-0.1x}=1-0.9\\\\e^{-0.1x}=0.1\\\\ln(0.1)=-0.1x\\\\-2.3=-0.1x\\\\x=23\ minutes[/tex]

~~~Hope this helps~~~ :)

The original price is $740.

[tex] \frac{(100 - 15)}{100} = \frac{629}{x} [/tex]

[tex]85x = 62900[/tex]

[tex]62900 \div 85 = x[/tex]

[tex]x = 740[/tex]
