Using the z-distribution, the 99% confidence interval for the proportion of all adult Americans that drank coffee in the previous 24 hours is: (0.61, 0.65).

A confidence interval of proportions is given by the following rule:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

For this problem, we have a 95% confidence level, hence the [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The estimate and the sample size are given as follows:

[tex]\pi = 0.63, n = 2815[/tex]

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.63 - 1.96\sqrt{\frac{0.63(0.37)}{2815}} = 0.61[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.63 + 1.96\sqrt{\frac{0.63(0.37)}{2815}} = 0.65[/tex]

Hence the 99% confidence interval for the proportion of all adult Americans that drank coffee in the previous 24 hours is: (0.61, 0.65).

The values of trigonometric function are tanθ = -1 and cotθ = -1.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

We have been given that trigonometric function

⇒ sinθ = √2/2

⇒ cosθ = -√2/2

We have to determine the function of tanθ and cotθ

Since tanθ = sinθ/cosθ

Substitute the values of sinθ = √2/2 and cosθ = -√2/2, we get

⇒ tanθ = (√2/2)/(-√2/2)

⇒ tanθ = (√2/2)×(-2/√2)

⇒ tanθ = -1

Since cotθ = cosθ/sinθ

Substitute the values of sinθ = √2/2 and cosθ = -√2/2, we get

⇒ cotθ = (-√2/2)/(√2/2)

⇒ cotθ = (√2/2)×(-√2/2)

⇒ cotθ = -1

Therefore, the values of trigonometric function are tanθ = -1 and cotθ = -1.

The mean and the variance of the given discrete distribution are as follows:

The distribution of waiting times is missing, and is given by the image at the end of the answer.

The question is also incomplete, but it asks for the mean and the variance of the distribution.

Hence, from the distribution off the image, considering the percentages as the probabilities, the mean is given by:

E(X) = 0.0299 x 1 + 0.1026 x 2 + 0.1496 x 3 + 0.2265 x 4 + 0.1581 x 5 + 0.1368 x 6 + 0.0769 x 7 + 0.0214 x 8 + 0.0299 x 9 + 0.0299 x 10 + 0.0385 x 15 =  5.0563 minutes.

Then, considering the mean found above, and it's formula, the variance is given as follows:

V(X) = 0.0299 x (1 - 5.0563)² + 0.1026 x (2 - 5.0563)² + 0.1496 x (3 - 5.0563)² + 0.2265 x (4 - 5.0563)² + 0.1581 x (5 - 5.0563)² + 0.1368 x (6 - 5.0563)² + 0.0769 x (7 - 5.0563)² + 0.0214 x (8 - 5.0563)² + 0.0299 x (9 - 5.0563)² + 0.0299 x (10 - 5.0563)² + 0.0385 x (15 - 5.0563)² = 7.9365 minutes².

Answer:

yes.

Step-by-step explanation:

The expression using factoring is 4 * (33 + 57)+ 8)

The expression is given as

(132 + 228)

Factor out 2 from the expression

So, we have

(132 + 228) = 2 * (66 + !14)

Factor out 2 from the expression

So, we have

(132 + 228) = 2 * 2 * (33 + 57)

This gives

(132 + 228) = 4 * (33 + 57)

Hence, the expression using factoring is 4 * (33 + 57)+ 8)

Answer:

-3x+14

Step-by-step explanation:

Answer:

  14.47 . . . units

Step-by-step explanation:

Given the vertices of triangle XYZ are (-1, 3), (3, 0) and (-1, -2), you want the perimeter rounded to hundredths.

The perimeter of a polygon is the sum of the lengths of the sides. When the points defining a side are on a vertical line, as with segment XZ, the length is the difference of y-coordinates.

When the points are not on a horizontal or vertical line, the distance between them can be found using the distance formula.

The distance between (x1, y1) and (x2, y2) is given by the formula ...

  d = √((x2 -x1)² +(y2 -y1)²)

The length of segment XY is ...

  d = √((3 -(-1))² +(0 -3)²) = √(4² +(-3)²) = √25 = 5

The length of segment YZ is ...

  d = √((-1 -3)² +(-2-0)²) = √((-4)² +(-2)²) = √20 ≈ 4.47

Side XZ has length (3 -(-2)) = 5, the difference of y-coordinates. Then the perimeter is ...

  P = XZ +XY +YZ = 5 +5 +4.47

  P = 14.47 . . . . units

The perimeter of the triangle is about 14.47 units.

The value of x in the isosceles trapezoid is 7.

An isosceles trapezoid can be defined as a trapezoid in which non-parallel sides and base angles are of the same measure.

The base angles of an isosceles trapezoid are the same.

Therefore,

8x - 12 = 5x + 9

subtract 5x from both sides of the equation

8x - 12 = 5x + 9

8x - 5x - 12 = 5x - 5x + 9

3x - 12 = 9

add 12 to both sides of the equation

3x - 12 = 9

3x - 12 + 12 = 9 + 12

3x = 21

divide both sides by 3

x = 21 / 3

x = 7

Therefore, the value of x in the isosceles trapezoid is 7.
