ladder is 70°. How high does the ladder reach up the side of the building?

The value of function f (8) is, - 42 which is negative.

Since, A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

The function is ,

⇒ f (x) = 6 (1 - x)

Now, WE can find the value of f (8) by substitute the value of x = 8 in above function,

⇒ f (x) = 6 (1 - x)

⇒ f (8) = 6 (1 - 8)

⇒ f (8) = 6 × - 7

⇒ f (8) = - 42

Thus, The value of function f (8) is, - 42 which is negative.

Yes, Timothy is correct because triangle AKLM was dilated by using a scale factor of 1.5 centered at the origin.

In Mathematics, dilation can be defined as a type of transformation that is typically used for enlarging or reducing the size of a geometric object but not its shape, based on the scale factor.

For the given coordinates of the preimage triangle KLM, the dilation with a scale factor of 1.5 from the origin (0, 0) would be calculated as follows:

Coordinate K (-1, 3) → Coordinate K' (-1 × 1.5, 3 × 1.5) = Coordinate K' (-1.5, 4.5).

Coordinate L (8, 4) → Coordinate L' (8 × 1.5, 4 × 1.5) = Coordinate L' (12, 6).

Coordinate M (10, -3) → Coordinate M' (10 × 1.5, -3 × 1.5) = Coordinate M' (15, -4.5).

In conclusion, the coordinates of the image triangle K'L'M after a dilation with a scale factor of 1.5 from the origin are (-1.5, 4.5), (12, 6), and (15, -4.5) as shown in the graph above, therefore, Timothy is correct.

Using the negative binomial distribution, it is found that:

a) \(E(X) = 15\)

b) \(Var(X) = 6.67\)

c) \(P(X = 12) = 0.0883\)

Negative binomial distribution:

It is the number of trials until q successes of a binomial variable, with p probability of success.

The expected value is:

\(E(X) = \frac{q}{p}\)

The variance is:

\(Var(X) = \frac{pq}{(1 - p)^2}\)

The probability mass function is:

\(P(X = x) = C_{x+q-1,q-1}(1 - p)^xp^q\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

In this problem, the parameters are: \(q = 6, p = 0.4\).

Item a:

\(E(X) = \frac{6}{0.4} = 15\)

Item b:

\(Var(X) = \frac{6(0.4)}{(1 - 0.4)^2} = 6.67\)

Item c:

\(P(X = 12) = C_{17,5}(0.6)^12(0.4)^6 = 0.0883\)

Answer: Non-Proportional

Step-by-step explanation:

A proportional pricing method would ensure that the various quantities of milk have the same relative price relating to their quantity. For instance, a half gallon of milk should be half the price of a full gallon of milk for it to be Proportional.

In this example, a gallon costs $3.89. If it were proportional then a half gallon would cost;

= 3.89/2

= $1.95

It instead costs $1.99 which means that it is Non-Proportional.

Answer:

Basic Concept:

Since there are no boys between 2 girls, we will take the 3 girls as 1 single unit and permute the seats

We have 6 slots (5 for boys and 1 for all 3 girls)

We have 6 slots and 6 people to sit on them (taking the 3 girls as one)

Permutations:

So, the total number of seating arrangements is 6P6

which will be equal to 6 factorial (6P6 = \(\frac{n!}{n! - r!}\) = \(\frac{6!}{6! - 6!}\) = 6! (since 0! = 1))

Total possible seating arrangements  = 6!

Total possible seating arrangements = 720

Step-by-step explanation:

10 is not less than 6, so 10 < r when r=6 is not true.

(a) 45 tens is equal to 450. :- True

(b) 12.3 is equal to 123 ones. :- True

(c) 80 tens is greater than 6 hundreds. :- True

(d) 43,200 is less than 50 thousands. :- True

(e) 60 hundreds = 6,000 :- True

Consider the first statement,

45 tens are equal to 450

So, 45 tens mean 45 times 10 is written as:

45 × 10 = 450

Hence, it's true.

Consider the second statement,

12.3 is equal to 123 ones.

Now, 123 ones is equal to 123 times 1.

123 × 1 = 123

Hence, the statement is true.

Consider the third statement,

80 tens is greater than 6 hundreds.

Now 80 tens = 80 × 10 = 800

Now, 6 hundreds = 6 × 100 = 600

Now, 800 > 600

Hence, the statement is true.

Consider the fourth statement.

43,200 is less than 50 thousands.

Now, 50 thousands = 50 × 1000 = 50,000

We know,

50,000 > 43,200

Therefore, the statement is true.

Consider the fifth statement,

60 hundreds = 6000

Now, 60 hundreds = 60 × 100 = 6000

Therefore, the statement is true.

Step-by-step explanation:

21(33)6O can be expressed as 13√(2(729)). The final answer is 13√1458.

Rewriting the expression 21(33)6 with a rational exponent as a radical expression yields 21(33)6O, which can be simplified as 21(33)2. The value of 21 is 2, while the value of 33 is 27. Hence, 21(33)2 is equivalent to 2(27)2

To rewrite the expression with a rational exponent as a radical expression, we make use of the property that any number raised to a rational exponent can be represented as a radical with an exponent equal to the denominator of the rational exponent.

In this case, the rational exponent is 6/3, which is equivalent to 2.

Hence, we can rewrite 21(33)6 as 21(33)2. Simplifying this expression yields 2(27)2, which is equal to 2(729).

To express this in radical form, we take the 13th root of 2(729), which gives us 13√(2(729)).

This can be further simplified as 13√1458.

To divide 30 into five parts such that the first and last parts are in the ratio of 2:3, we can follow these steps:

1. Determine the ratio between the first and last parts. In this case, it is 2:3.

2. Add the ratio values together to find the total number of parts: 2 + 3 = 5.

3. Divide the total value (30) by the total number of parts (5) to find the value of each part: 30 / 5 = 6.

4. Multiply the value of each part by the respective ratio values to obtain the individual parts:

- First part: 2 * 6 = 12

- Second part: 6

- Third part: 6

- Fourth part: 6

- Last part: 3 * 6 = 18

Therefore, the five parts of 30, with the first and last parts in the ratio of 2:3, are 12, 6, 6, 6, and 18.

Answer:

b = 56km is the answer.

Step-by-step explanation:

a (Northbound train) = 33km

b (Eastbound train) = ?

c (Distance between them) = 65km

According to the Pythagorean theorem,

a² + b² = c²

33² + b² = 65²

1089 + b² = 4225

b² = 4225 - 1089

b² = 3136

b = 56km

∴ the eastbound train has travelled 56km.

The probability of choosing a preschooler who is a girl and prefers the color blue is 0.3 or 30%.

The total number of preschoolers who were asked about their color preference is 70. Out of these, 35 girls chose pink, 15 girls chose blue, 5 boys chose pink, and 15 boys chose blue.

To find the probability of choosing a girl who prefers blue, we need to use the formula:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

Here, the favorable outcome is choosing a girl who prefers blue. We can see that 15 girls chose blue as their preferred color. Out of these, we need to choose a girl, so the total number of favorable outcomes is 15.

The total number of outcomes is the total number of preschoolers, which is 70. Out of these, the number of girls is 35+15=50. Therefore, the total number of outcomes where a girl can be chosen is 50.

Putting these values in the formula, we get:

Probability = 15/50 = 0.3

The dot product of the D⋅n is 32.

According to the statement

We have given the value of n vector and d matrix and we have to find the dot product of these.

So, For this purpose,

The given values:

n = {-2,-1} and D = [−4423].

The dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers, and returns a single number.

So, The d matrix become

\(D = \left[\begin{array}{cc}-4&4&\\2&3&\\\end{array}\right]\)

Now solve it with the help of multiplication then the matrix become

D = (-12, -8)

and n = {-2,-1}

Now multiply both terms with the dot product.

So, the dot product of the both terms will become

D.n = 24 +8

Then

The output of the dot product of both terms is 32.

So, The dot product of the D⋅n is 32.
