Answer:

The expected number of keys she will try before she opens the door is 4.5.

Step-by-step explanation:

A woman has eight keys on a key ring, one of which fits the door she wants to unlock.

Each of them is equally as likely to be the one to work, which means that this situation is represented by an uniform distribution with lower bound [tex]a = 1[/tex] and upper bound [tex]b = 8[/tex].

Find the expected number of keys she will try before she opens the door.

The expected value of the uniform distribution is given by:

[tex]E = \frac{a + b}{2}[/tex]

Considering [tex]a = 1, b = 8[/tex], as is the case in this exercise:

[tex]E = \frac{1 + 8}{2} = 4.5[/tex]

The expected number of keys she will try before she opens the door is 4.5.

Answer:

Step-by-step explanation:

mean is average, so if we label the first through fifth days of january a-e we can solve it.

So average of the first four is (a+b+c+d)/4 = 1 and the first five is (a+b+c+d+e)/5 = 2.  Since it's easy, let's get rid of the fraction in both.

(a+b+c+d)/4 = 1 and (a+b+c+d+e)/5 = 2

a+b+c+d = 4 and a+b+c+d+e = 10

Now, we know a+b+c+d is 4, so we can replace that in the second equation

a+b+c+d+e = 10

4 + e = 10

e = 6

ad since e is the fifth day, we know the temperature of it.  Let me know if something here didn't make sense

here, diameter is 4 cm

radius=diameter/2

=4/2 cm

=2 cm

now use formula pie (r)^2 where pie is 3.14

=pie *(r)^2

=3.14*(2cm)^2

=12.56 cm^2

Step-by-step explanation:

Step-by-step explanation:

Given :-

And we need to find out the equation of the circle. Since the diameter is 24 u therefore it's radius will be 12 u . Now we can use the Standard equation of circle to find out the equation .

Standard equation of circle :-

[tex]\implies (x-h)^2+(y-k)^2 = r^2 [/tex]

[tex]\implies (x-(-13))^2+(y-(-2))^2 = 12^2 \\\\\implies ( x+13)^2+(y+2)^2=144 \\\\\implies x^2+169+26x+y^2+4+4y=144\\\\\implies x^2+y^2+26x+4y+ 29 =0[/tex]

The bases for a cylinder must be parallel and congruent discs.

In mathematics, a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.

These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis.

The cylinder has it base as a circle, it has two circular bases upside and downside.

The base of the cylinder is the circular shape which can be seen in the ends of the cylinder.

Properties of base of cylinder-

The base of the cylinder is circular in shape.

There are two bases of a cylinder.

The bases of a cylinder are always parallel and congruent to each other.

These bases are in the shape of discs.

Hence, the bases for the cylinder should be parallel and congruent which are in the shape of discs.

Answer:

  x = 0.8

Step-by-step explanation:

If you mean y = √(1 -x²), then the curves cross at x=0.8.

__

If you equate the y-expressions, then square both sides, you have ...

  √(1-x²) = 2x-1

  1 - x² = (2x -1)² = 4x² -4x +1

  0 = 5x² -4x . . . . . subtract the left-side expression

  x(5x -4) = 0   ⇒   x = 0, or x = 4/5

The x=0 solution is extraneous.

The two equations are equal at x = 4/5.

Answer:

height: 7 in

base: 14 in

Step-by-step explanation:

Let the height of the triangle equal x. This means that the base can be represented by the expression 2x. Now we plug these values into the area formula for a triangle:

A = bh / 2

49 = x * 2x / 2

And simplify

49 = x^2

We can find the square root of both sides to get x = 7, so the height is 7 inches. Since the base is twice the height, it is 14 inches.

Answer:

[tex]h=7,\\b=14[/tex]

Step-by-step explanation:

Since the base is twice as long as the height, set up the following proportion:

[tex]b=2h[/tex].

The area of the a right triangle is equal to [tex]A=\frac{1}{2}bh[/tex], where [tex]b[/tex] is a base of the triangle and [tex]h[/tex] is the respective height.

To solve for height, set up the equation (substituing [tex]b=2h[/tex]:

[tex]\frac{1}{2}\cdot2h\cdot h=49,\\2h^2=98,\\h^2=49,\\h=\boxed{7}[/tex]

To solve for base, substitute [tex]h=7[/tex] in the proportion [tex]b=2h[/tex]:

[tex]b=2(7),\\b=\boxed{14}[/tex]

the crate weighs 5.5 and each apple weighs 0.33 therefore --> 5.5 + 0.33a is the algebraic expression.  You know the totla weight, so you can set that expression equal to 58.3

5.5 + 0.33a = 58.3

Solve for a, but isolating a (subtract 5.5 from each side)

0.33a = 52.8

Divide both sides by 0.33 to solve for a

The planning value for the population standard deviation is of 4330.

Step-by-step explanation:

Uniform probability distribution:

The uniform probability distribution has two bounds, a and b. The standard deviation is given by:

[tex]S = \sqrt{\frac{(b-a)^2}{12}}[/tex]

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between 20000 and 35000.

Uniform in this interval, so [tex]a = 20000, b = 35000[/tex]

What is the planning value for the population standard deviation?

[tex]S = \sqrt{\frac{(35000 - 20000)^2}{12}} = 4330[/tex]

The planning value for the population standard deviation is of 4330.

Step-by-step explanation:

The regression fits the data well leavubgbiut just one of the points, this shows there is a strong relationship between the plotted variables. Also, we have to look at the direction of the regression line which will give us an idea of the slope, hence the type of correlation between the two variables (either positive or negative relationship). In this case the slope is positive and hence the correlation Coefficient will be positive as well. Hence we can say there is a strong positive relationship between the variable. The only option which depicts this association is 0.872
