1. Imagine a triangle with base side 36 feet and Kate at the right with the angle of elevation, 24 degrees. We can use tangent:

tan 24 = o/a ; tan(24) = o/36 ; 36(tan(24)) = o ; o = 16 feet

This is how tall the screen is.

2. We do a similar operation:

tan(74) = o/a ; tan(74) = 555/a ; a = 555/tan(74) ; a = 159.1 feet

Whole Numbers: The collection of natural numbers that include the number 0. Integers are whole integers that are next to their counterparts (negative numbers). Real numbers would be any integers that can be stated as fractions. Any number that cannot be expressed as a fraction is irrational.

Many operations, like measuring, counting, and indexing, require the use of numbers. According to their characteristics, there are several sorts of numbers, including natural numbers, whole figures, rational or irrational numbers, integers, actual values, complex numbers, and even odd numbers, etc.

Let the number be y

5 is subtracted from the number. This can be written as:

y – 5

The difference is tripled. This can be written as:

3(y – 5)

The result of the difference tripled is 23 more than the number. This can be written as:

3(y – 5) = 3 + y

Thus, we can obtain the value of y as follow:

3(y – 5) = 3 + y

Step-by-step explanation:

Answer:

Daniel is 8 years old now

Step-by-step explanation:

Let Kevin's age now be K and let Daniel's age now be D

"Kevin is 3 times as old as Daniel"

Translation: K = 3D

"4 years ago, Kevin was 5 times as old as Daniel"
4 years ago Kevin's age = K - 4
4 years ago Daniel's age = D - 4
4 years ago, Kevin was 5 times as old as Daniel.

Translation: K - 4 = 5(D - 4)
K - 4 = 5D - 20

Simplify this equation:
Add 4 to both sides:
K - 4 + 4 = 5D - 20 + 4

K = 5D - 16

Substitute K = #D:
3D = 5D - 16

Subtract 5D from both sides:
3D - 5D = - 16
-2D = -16

or

2D = 16   (multiply by - 1)

D = 16/2 = 8

and

K = 3D = 3 x 8 = 24

Now, Kevin is 24 years old and Daniel is 8 years old

Verify
If Kevin is 3x older than Daniel who is 8 now,
Kevin's age now = 3 x 8 = 24  Check

4 years ago, Daniel was 8 - 4 = 4 years
4 years ago, Kevin was 24 - 4 = 20
Kevin's age 4 years ago = 5 x 4 = 20 Check

The vector "p" that represents "a's closest point" on the line "b" spans is the orthogonal projection of vector "a" onto vector "b."

So the vector "p" that represents "a's closest point" on the line "b" spans is the orthogonal projection of vector "a" onto vector "b." The following is the formula for projecting "a" orthogonally onto "b": CSS Copy: p = (dot(a, b) / dot(b, b)) * b, where "dot" stands for the dot product of the two vectors.

The procedures to determine the orthogonal projection of a vector "a" onto a vector "b" are as follows:

The p-value can be calculated from the Z-score of the observed result using the Z-table, which is a table of values for the standard normal distribution.

The p-value is the probability of getting a result at least as extreme as the one observed, given that the null hypothesis is true. It is calculated from the Z-score of the observed result, which is a measure of how many standard deviations away from the mean the observed result is. To calculate the p-value from a Z-score, you need to use the Z-table, which is a table of values for the standard normal distribution. The Z-table shows the probability of a given Z-score, or the area under the normal distribution curve to the left of the Z-score. To find the p-value associated with a given Z-score, you simply look up the probability in the Z-table, and subtract this probability from 1. This gives you the p-value, which is the probability of getting a result at least as extreme as the one observed, given that the null hypothesis is true.

1. Answer: The price of Andrea's tacos is $8.

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

Tip amount: $2.0

Percentage: 25% = 0.25 (decimal form, 25/100=0.25)

So, if we multiply the taco's price (x) by the percentage (0.25) we will obtain the amount of the tip (2).

Mathematically speaking:

x (0.25) = 2

Solving for x

x = 2/0.25

x = 8

The rank (m) and the nullity (n) is the Matrix A is 5 and 3 respectively according to the planes given.

The maximum number of its linearly independent columns (or rows ) of a matrix is called the rank of a matrix. And the dimension of the null space of A, also called the kernel of A.

Given null space of [tex]L_{A}[/tex] is a plane in [tex]lR^{3}[/tex] .

So nullity of matrix A is A = 2

Since the dimensions of a plane in [tex]lR^{3}[/tex] is 2.

Also the range is spanned by non-vector V in [tex]R^{5}[/tex].

So rank of matrix A is A = 1

Clearly the linear transformation is from [tex]lR^{5}[/tex] to [tex]lR^{3}[/tex],

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We can use the Pythagorean theorem to find the length of the guy wire.

Let's call the length of the guy wire "g".

Then we have a right triangle with hypotenuse g, one leg of length 7 ft, and the other leg of length 19 ft.

Using the Pythagorean theorem, we have:

g² = 7² + 19²

g² = 49 + 361

g² = 410

Take square root on both sides

g = 20.24

The critical value for the 0.05 level of significance is k = 21.

To find the critical value, we can use the binomial distribution. The binomial distribution models the number of successes in n independent Bernoulli trials, each with probability p of success. In this case, the number of successes is the number of dog owners who say Woof Chow is their regular brand, and the number of trials is n = 100. The null hypothesis is that the true market share of Woof Chow is 25%, and the alternative hypothesis is that it is not 25%.

We can use the binomial cumulative distribution function (CDF) to find the critical value. The CDF gives the probability of getting k or fewer successes in n trials, given a probability of success p. The critical value is the smallest value of k such that the CDF at k is greater than or equal to 1 - alpha, where alpha is the level of significance. In this case, alpha = 0.05.

So, we want to find the smallest k such that:

P(X <= k) >= 1 - 0.05

where X is a random variable representing the number of dog owners who say Woof Chow is their regular brand. We can use a binomial calculator or a software package to calculate the binomial CDF, or we can use a table of critical values for the binomial distribution.

The critical value for the 0.05 level of significance is k = 21. This means that if the true market share of Woof Chow is 25%, then the probability of getting 23 or more dog owners who say Woof Chow is their regular brand is less than 0.05. Since the observed number of dog owners who say Woof Chow is their regular brand is 23, which is greater than 21, we can reject the null hypothesis that the true market share is 25%.

This means that based on the survey results, we cannot conclude that Woof Chow has a market share of 25%. The survey results suggest that Woof Chow may have a market share that is greater than 25%.

The original number in the word problem is 77.

Let's call the original two-digit number "x".

Information from the problem

the sum of the digits in x is 14.

So, we can write the number as x = 10a + b,

where a and b are the tens and ones digit, respectively, and a + b = 14.

Reversing and doubling the original number gives us 2(10b + a)

= 20b + 2a.

Adding the original number, x, and the doubled, reversed number, 2(10b + a),

we have 3x = 222.

Substituting x = 10a + b

3(10a + b) = 222

30a + 3b = 222

30a = 222 - 3b

Since the sum of the digits is 14, a + b = 14, so we can substitute for a in the equation:

30(14 - b) = 222 - 3b

420 - 30b = 222 - 3b

198 = 27b

In statistics, the No Information Rate (NIR) is a measure of the accuracy of a classification model that predicts the most frequent class as the outcome for all cases. It represents the accuracy rate that can be achieved by simply guessing the most frequent outcome without using any predictive model or variable.

The NIR is commonly used as a benchmark for evaluating the performance of classification models, as any model that performs worse than the NIR is considered to be poorly performing. Conversely, a model that performs better than the NIR is considered to have some predictive power beyond simply guessing the most frequent outcome.

Recall that the rea of a Right Angled Triangle = 1/2 B*H;

B = 15ft

H = 35ft

Area of Δ = 1/2 * 15 *35

Area of Triangle = 262.5ft
