My name is math JR LOL

Step-by-step explanation:

Answer:

The height of first tree is

[ 5.5+18tan(50 degrees) ] ft. This is approximately 26.95 ft.

Angle of elevation from Jimmy's eyes to top of tree is arctan([20+18tan(50 degrees)] /18). This is approximately 66.53 degrees.

Step-by-step explanation:

It would help you to draw a picture for both of these.

You have a person whose height is 5.5 ft and from there horizontal gaze they see a bird from a 50 degree angle of elevation. He is standing 18ft ftom the tree.

So we will first want to find the distance from his eyesight level to the top of the tree. We can do this using the tangent ratio since we have the opposite and adjacent measurements.

Let the distance from eyesight level to the top of the tree be r.

tan(50)=r/18

Multiply both sides by 18:

18tan(50)=r

Now the height of the tree is

[5.5+18tan(50 degrees)] ft.

Now if he is the middle of two trees, then he 18 ft from the 2nd tree.

Since he says the height is 20ft taller than the first tree then it's height is

[20+5.5+18tan(50 degrees)] ft.

Now since we want to find his angle of elevation to the top of the 2nd tree we need to take out his height given us the distance from his eyesight level to the top of the tree which is

[20+18tan(50 degrees)] ft..

So again we are using the tangent ratio.

Let this angle if elevation be P.

tan(P)=[20+18tan(50 degrees)] /18

Take arctan() of both sides:

P=arctan([20+18tan(50 degrees)] /18)

The first two numbers in each row of the relative frequency table represent the percentage of cars and trucks of a particular color out of the total number of vehicles in the parking lot.

To create a relative frequency table, we need to divide the frequency of each color by the total number of vehicles (65) and then multiply by 100 to get a percentage.

Relative Frequency Table by Color:

The first two numbers in each row must add up to 100% because we are calculating the relative frequency of each color with respect to the total number of vehicles (65). Therefore, the percentage of cars and trucks of each color must add up to 100% of that color's total frequency. The total row must also add up to 100% because it represents the entire population of vehicles.

Given:

Number of small dogs = 18

Number of medium-sized dogs = 12

Number of large dogs = 10

To find: probability that a medium-sized dog will be chosen

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favourable outcomes/total number of outcomes

Total number of dogs = 18 + 12 + 10 = 40

Number of medium-sized dogs = 12

So,

probability that a medium-sized dog will be chosen = Number of medium-sized dogs/Total number of dogs = \(\frac{12}{40}=0.3\)

The least common multiple (LCM) of the polynomials x² - 32x - 10 and 2x + 10 is 2(x + 2)(x - 10)(x + 5).

To calculate the LCM, we need to find the polynomial that contains all the factors of both polynomials, while excluding any redundant factors.

Let's first factorize each polynomial to identify their prime factors:

x² - 32x - 10 = (x + 2)(x - 10)

2x + 10 = 2(x + 5)

Now, we can construct the LCM by including each prime factor once and raising them to the highest power found in either polynomial:

LCM = (x + 2)(x - 10)(2)(x + 5)

Simplifying the expression, we obtain:

LCM = 2(x + 2)(x - 10)(x + 5)

Therefore, the LCM of x² - 32x - 10 and 2x + 10 is 2(x + 2)(x - 10)(x + 5).

The equation holds for all n, we've proved by strong induction that the formula an = (1 + 3n)(-1)^n is correct for all n ≥ 0.

Based on the given recurrence relation, we can start computing the first few terms of the sequence:

a0 = 1

a1 = -2

a2 = -2a1 - a0 = -2(-2) - 1 = 3

a3 = -2a2 - a1 = -2(3) - (-2) = -8

a4 = -2a3 - a2 = -2(-8) - 3 = 19

a5 = -2a4 - a3 = -2(19) - (-8) = -30

...

From these calculations, it's difficult to spot a pattern or function that describes the sequence, so we'll use strong induction to prove a general formula for the nth term.

First, let's assume that the formula for an is of the form an = A(1)⋅r1n + A(2)⋅r2n, where A(1) and A(2) are constants to be determined, and r1 and r2 are the roots of the characteristic equation r2 + 2r + 1 = 0, which is obtained by substituting an = r^n into the recurrence relation and solving for r.

Factoring the quadratic equation, we get (r+1)^2 = 0, so r = -1 is a repeated root. This means that the general solution is of the form an = (A + Bn)(-1)^n, where A and B are constants determined by the initial conditions a0 = 1 and a1 = -2.

To find A and B, we use the initial conditions:

a0 = 1 = A + B(0)(-1)^0 = A

a1 = -2 = A + B(1)(-1)^1 = A - B

Solving for A and B, we get A = 1 and B = 3. Therefore, the formula for the nth term is:

an = (1 + 3n)(-1)^n

Now we need to prove that this formula holds for all n ≥ 0. We'll use strong induction and assume that the formula holds for all k < n. Then we'll show that it holds for n as well.

Substituting the formula into the recurrence relation, we get:

an = -2an-1 - an-2

(1 + 3n)(-1)^n = -2(1 + 3(n-1))(-1)^(n-1) - (1 + 3(n-2))(-1)^(n-2)

Simplifying this equation, we get:

(-1)^n = (-1)^n

Since the equation holds for all n, we've proved by strong induction that the formula an = (1 + 3n)(-1)^n is correct for all n ≥ 0.

Step-by-step explanation

45 x 0.9%= 0.405

Answer:

x = 5000

Step-by-step explanation:

Let us say 45 is 0.9% of x

=> 0.9% × x = 45

=> 0.9/100 × x = 45

=> x = 45 × 100/0.9

=> x = 4500/0.9

=> x = 45000/9

=> x = 5000

z=72°+57°(EXTERIOR ANGLES OF A TRIANGLE)

Rounded to four decimal places, the p-value is 0.0844.

To determine the p-value for this hypothesis test, we need to follow these steps:

Step 1: State the null and alternative hypotheses.

Null hypothesis: The percentage of readers who own a laptop is 26%.

Alternative hypothesis: The percentage of readers who own a laptop is different from 26%.

Step 2: Determine the test statistic.

We can use a z-test for proportions since we have a large enough sample size and we know the population proportion. The formula for the test statistic is:

z = (p - p) / √(p(1-p) / n)

where p is the sample proportion, p is the hypothesized population proportion, and n is the sample size.

Using the given values, we have:

z = (0.17 - 0.26) / √(0.26(1-0.26) / 100)

z = -1.72

Step 3: Determine the p-value.

Since this is a two-tailed test, we need to find the area in both tails of the standard normal distribution that corresponds to a z-score of -1.72. Using a table or a calculator, we find that the area in the left tail is 0.0422 and the area in the right tail is also 0.0422.

Therefore, the p-value is the sum of the areas in both tails:

p-value = 0.0422 + 0.0422

Functions are another key idea in programming because they let you put a piece of code that performs a specific purpose inside a specified block and then call that code whenever you need it with a single, brief command rather than repeatedly typing the same code.

Code units that are "self contained" and carry out a particular purpose are called functions. Typically, functions "take in," "process," and "return" data and results. Once a function has been developed, it may be utilized countless times.

The researcher is using convenience sampling as their sampling strategy. Convenience sampling involves selecting participants who are readily available and easily accessible.

In this case, the researcher is approaching people who pass by them on a street corner, which is a convenient and accessible location.

Convenience sampling is often used when time, resources, or logistics constraints make it challenging to implement more rigorous sampling methods. While convenient, this sampling strategy may introduce bias and may not represent the larger population accurately. People who pass by a specific street corner may not be representative of the entire population of interest, leading to potential sampling bias.

However, convenience sampling can be useful for obtaining quick insights or conducting exploratory research. It allows researchers to collect data efficiently and can serve as a starting point for further investigation. Nevertheless, it is important to acknowledge the limitations and potential biases associated with convenience sampling when interpreting the results.

The correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A positive correlation means that as one variable (in this case, happiness) increases, the other variable (GPA) also tends to increase. The magnitude of the correlation coefficient, which ranges from -1 to 1, represents the strength of the relationship. A value of 0.90 indicates a very strong positive linear correlation, suggesting that there is a consistent and significant relationship between happiness and GPA.

This means that as the level of happiness increases among high school students, their GPA tends to be higher as well. The correlation coefficient of 0.90 suggests a high degree of predictability in the relationship between these two variables.

It is important to note that correlation does not imply causation. While a strong positive correlation indicates a relationship between happiness and GPA, it does not necessarily mean that one variable causes the other. Other factors or variables may also influence the relationship between happiness and GPA.
