A data set is normally distributed with a mean of 8.1 and a standard deviation of 3.8.
What percentage of the data is above 8.6?
Enter your answer as a number to the nearest whole percentage, like this: 42%

The area bounded by the Curves y=4-x² and y = 2x + 1 is 10 1/3 units.

Area is the amount of space occupied by a two dimensional shape or object.

y = 4 - x² and y = 2x + 1

4 - x² = 2x + 1

x² + 2x - 3 = 0

(x + 3)(x - 1) = 0

x = -3; or x = 1

The area (A) is given by:

[tex]A=\int\limits^1_{-3} {x^2+2x-3} \, dx \\\\A=10\frac{1}{3}[/tex]

The area bounded by the Curves y=4-x² and y = 2x + 1 is 10 1/3 units.

Answer:

5 payments

Step-by-step explanation:

First we add up the prices for the lunches and the movies :)

3 x 5 = 15

15 + 9.5 = 24.5

Second we subtract the 24.5 from the 35 :)

35 - 24.50 = 10.5

Now we divide the price of the cd player by the 10.50 to get the total number of payments :)

50/10.5 = 5

Finally to check it one more time, we multiply the 10.5 by 5 and if it equals 50 or over, it is correct!! :D

10.5 x 5 = 52.5!!!

You did it!

Your correct answer is 5 payments!!

Have a great day!!!

Hello ;  

y= -6

The amount of water that the tank will contain at 6:10 PM that day is 4174 L.

The conversion rate of a physical quantity is the method by which a unit of measurement is changed from one process to another by following a standard conversion rate and dimensional analysis.

From the information given:

The difference in the water in the tank within these two periods is:

= 22917 L - 8077 L

= 14840 L

In one minute, the amount of Liter is:

= 14840/160

= 92.75 Liter/minute

Similarly, between 6:10 pm and 5:25 pm, there are 45 minutes difference.

Therefore, the amount of water that the tank will contain at 6:10 PM that

day is;
= 45 minutes × 92.75 Liter/minute

= 4174 Liters

Step-by-step explanation:

A point is infinitely small and comprised of a single location.

hope this helps!! p.s. i really need brainliest :)

The object that is infinitely small among the option is a point. Option A is correct.

All over the world, most things are in use as of common quantity, so people all over the world agree that they have to follow a common system of measurement and that the common system of measurement is called standard measurement.

Here,
The object that is infinitely small among the option is a point. Because there is no instrument that can measure the point. Since a point is nothing but a demonized dot. While line, ray, or plane are infinitely long and their measure can be possible.

Thus, the object that is infinitely small among the option is a point. Option A is correct.

Answer:

c=98.92

Step-by-step explanation:

first I figured out the number of years between 1990 and 2014.I basicly just subtracted 1990 from 2014 then times it by 2.85 the added 30.52

The cost in billions of dollars in​ 2014 would be 98.92

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We are given that national cost C in billions of dollars for dental services can be modeled by the linear equation c=2.85n+30.52​, where n is the number of years since 1990.

Then c=2.85n+30.52

Solving then subtracted 1990 from 2014

2014 - 1990

= 24

Now

c = 2.85 (24) +30.52

c = 68.4 +30.52

c = 98.92

Hence,  the cost in billions of dollars in​ 2014 would be 98.92

Answer:

1/5

Step-by-step explanation:

Refer to the image for the region. I've chosen to "scan" the region horizontally for convenience sake, so x varies for values between the green and the red line, and y varies from 0 to 1.

The two lines have equations [tex]x=7-6y[/tex] (red line) and [tex]x=7-7y[/tex] (green line). Since we're integrating first with respect to x, it's easier to write the equation like that and not as [tex]y=mx+q[/tex] since they will become our new limits of integration

Our double integral will become

Step-by-step explanation:

So image that the wire just sliced that piece of the cube right off:

It would give you a triangular prism,

HOWEVER, this is asking for the cross section:

The part of this triangular prism that was actually connected to the cube

and in this case, it would show that the bottom of the cut off part is rectangle.

You can also think of this as: What shape would be left over on the cube?

Cutting this piece off would give you a shape left over that is a rectangle.

Answer:

18

Step-by-step explanation:

Hello!

In the Pythagorean theorem, the summation of the square of the legs in a right triangle is equal to the square of the hypotenuse.

Let a and b be the legs, and c is the hypotenuse.

a² + b² = c²

In this equation, the hypotenuse is 30, and the measure of one leg is 24.

We can solve this by plugging in the values.

So the missing side length is 18.

Answer:

c = 292; h = 225

c = cheeseburgers

h = hamburgers

Step-by-step explanation:

2 Equations;

h + c = 517

c = h + 67

h + h + 67 = 517  |  Substitution

2h + 67 = 517 | Subtract on Both Sides

2h = 450  | Divide

h = 225

Plug the h value in the second equation to find the value of c.

c = h +67 | Original Equation

c = 225 + 67 | Substitution

c = 292
