A 30-m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 32 m. Find the length of the shadow. If necessary, round your answer to the nearest tenth.

The expected value of your net winnings, x, is $1.39.

To find the expected value of x (net winnings), first calculate the probability of each outcome and multiply it by the respective winnings. There are 6 sides on each die, so there are 36 possible outcomes (6 sides on red die * 6 sides on blue die).

1. Winning $5: Sum of 5, 6, or 8 has 4+5+5 = 14 successful outcomes. Probability = 14/36.
2. Winning $2: Sum of 4, 9, or 10 has 3+4+3 = 10 successful outcomes. Probability = 10/36.
3. Losing $4: Sum of 2, 3, 7, 11, or 12 has 1+2+6+2+1 = 12 successful outcomes. Probability = 12/36.

Now, multiply each probability by its respective winnings/loss and sum them to find the expected value of x:

E(x) = ($5 * 14/36) + ($2 * 10/36) + (-$4 * 12/36) = $1.39

Step-by-step explanation:

Divide -187 by 2

Answer:

To solve this problem, we can use the cumulative distribution function (CDF) of the normal distribution.Given:

Mean (μ) = 133 lb

Standard Deviation (σ) = 6.4 lb

Weight (X) = 126.6 lb

We can use the formula for the standard normal distribution to calculate the z-score:

z = (X - μ) / σ

Plugging in the values, we get:z = (126.6 - 133) / 6.4 = -0.984375

Now, we can use a standard normal distribution table or a calculator with a built-in normal distribution function to find the cumulative probability (P) associated with the z-score of -0.984375.

Using a standard normal distribution table, we find that the cumulative probability for a z-score of -0.984375 is approximately 0.1611.

So, approximately 16.11% of the registered female Great Danes in the United States weigh less than 126.6 lbs.

Tracey paid approximately 29.8% of the original price for the item.

To find the percentage of the original price that Tracey paid, we can use the formula:

Percentage = (Amount Paid / Original Price) * 100

Let's plug in the given values:

Percentage = (155 / 520) * 100

Percentage = 0.2980769230769231 * 100

Percentage ≈ 29.8%

Yes is it possible to construct a triangle with sides 4 cm 5 cm and 4.5 cm

What is Triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Concept:

Yes. It is possible to construct a triangle with lengths of its sides 4 cm,5 cm and 4.5 cm because the sum of two sides of a triangle is greater than the third side.

A triangle cannot be constructed if the two sides' sum equals the third side because then the two sides will also be the third side. As a result, for the triangle to be created, the sum of the two sides must be greater than the third side.

Any two triangle sides' lengths added together always equal the third side.

The triangle inequality can be used to calculate the best upper estimate of the size of the sum of two numbers in terms of the sizes of the separate numbers in mathematical analysis. if and only if the vector y is a nonnegative scalar of the vector x.

Answer:

y = - \(\frac{4}{5}\) x + \(\frac{2}{5}\)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 4y = 5x + 3 into this form by dividing the 3 terms by 4

y = \(\frac{5}{4}\) x + \(\frac{3}{4}\) ← in slope- intercept form

with slope m = \(\frac{5}{4}\)

Given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{\frac{5}{4} }\) = - \(\frac{4}{5}\) , thus

y = - \(\frac{4}{5}\) x + c ← is the partial equation

To find c substitute (3, - 2) into the partial equation

- 2 = - \(\frac{12}{5}\) + c ⇒ c = - 2 + \(\frac{12}{5}\) = \(\frac{2}{5}\)

y = - \(\frac{4}{5}\) x + \(\frac{2}{5}\) ← equation of perpendicular line

Answer:

5 1/7 pages in one hour. And what does "A.B.C.D." Mean?

Step-by-step explanation:

The power to which a number or expression is raised is called the exponent.

1. An exponent is a mathematical notation that represents the power to which a number or expression is raised. It is written as a superscript number or variable placed above and to the right of the base number or expression.

2. The base number or expression is the number or expression that is being multiplied repeatedly by itself, raised to the power of the exponent.

3. The exponent tells us how many times the base number or expression should be multiplied by itself. For example, in the expression \(2^3\), the base is 2 and the exponent is 3. This means that 2 should be multiplied by itself three times: 2 * 2 * 2 = 8.

4. The exponent can be a positive whole number, a negative number, zero, or a fraction. Each of these cases has different interpretations:

  - Positive exponent: Indicates repeated multiplication. For example, \(2^4\)means 2 multiplied by itself four times.

  - Negative exponent: Indicates the reciprocal of the base raised to the positive exponent. For example, \(2^{-3\) means 1 divided by \(2^3\).

  - Zero exponent: Always equals 1. For example, \(2^0\) = 1.

  - Fractional exponent: Represents a root. For example, \(4^{(1/2)\)represents the square root of 4.

5. Exponents follow certain mathematical properties, such as the product rule \((a^m * a^n = a^{(m+n)})\), the quotient rule \((a^m / a^n = a^{(m-n)})\), and the power rule \(((a^m)^n = a^{(m*n)})\).

Remember to use these rules and definitions to correctly interpret and evaluate expressions involving exponents.

Answer:

Step-by-step explanation:

This query relates to prices. Let's use the rate for a cold tap to represent Rc and hot water to represent Rh.

Therefore,

Since R = V/t, where t is the fill-in time, determines the rate at which the volume V tab is filled. The following can be written for both of them:

Rc = V/17

Rh = V/t

Rc + Rh = V/7

where t is the time that we need to find.

V/17 + V/t = V/7

Divide both sides by V to get:

1/17 + 1/t = 1/7

Rearrange:

1/t = 1/7 - 1/17

Bring to common denominator:

1/t = (17 - 7)/(7*17) = 10/119

Take an inverse:

t = 119/10 = 11.9 minutes.

b = $2.40

d = $5.70

Step-by-step explanation:

d = hot dog and b = hot dog buns

Equations:

2d + 5b = $23.40

3d + 2b = $21.90

-------------------------------subtract these two equations

-d + 3b = $1.50

3b - $1.50 = d

Substitute:

3d + 2b = $21.90

3(3b - $1.50) + 2b = $21.90

9b - $4.50 + 2= $21.90

11b = 26.40

b =  $2.40

Substitute again but this time with b:

3d + 2b = $21.90

3d + 2($2.40) = $21.90

The derivative of f(x) is:

f'(x) = 24x^3 - 38

To find the derivative of the function f(x) = 6x^4 - 38x + e^3, we differentiate each term separately using the rules of differentiation.

The derivative of 6x^4 with respect to x is:

f'(x) = 4 * 6x^3 = 24x^3

The derivative of -38x with respect to x is:

f'(x) = -38

The derivative of e^3 with respect to x is:

f'(x) = 0
