Some living expenses are fixed and won’t change often, such as your monthly rent. Other expenses are adjustable, such as food and clothing. That means that your spending and savings might differ from month to month, and that’s okay. Having a budget ensures you’re prepared and in a good financial place for whatever comes your way.

Hope this helps :)

Pls mark brainliest :3

And have an amazing day <3

Answer:

True

Step-by-step explanation:

I believe living expenses don't vary, due to the fact that every month you'll normally buy the same amount of groceries and gas. (Key word is that they expenses don't usually vary) Meaning that if you have to prepare for a party or a dinner it would be an abnormal variation.

The rate of change is -1/2

Initial point is (-2,-1)

What is slope ?

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

Consider any two pairs of points:

(-2,-1)  and (0,-2)

The slope is the same as the rate of change

Rate of change = change in y values/change in x values

                         = (-2 - (-1) ) / (0-(-2))

                         = ( -2 + 1) / (+2)  

Rate of change  = (-1/2)

If the defendeant is guilty, the probability that the jury makes the correct decision is approximately 0.476.

To calculate the probability that the jury makes the correct decision, we need to consider two cases: the defendant is guilty and the defendant is not guilty.

Let's start with the case where the defendant is guilty. The probability that any individual juror makes the correct decision on the defendant is 0.80. Therefore, the probability that at least 10 out of 12 jurors make the correct decision is given by the binomial distribution:

P(at least 10 out of 12 jurors say "guilty") = sum of P(k jurors say "guilty") for k = 10, 11, 12

Using a binomial calculator or formula, we can find that this probability is approximately 0.952.

Now let's consider the case where the defendant is not guilty. In this case, the probability that any individual juror makes the correct decision is 0.20 (since they should say "not guilty"). Therefore, the probability that at least 10 out of 12 jurors say "guilty" when the defendant is actually not guilty is given by the same binomial distribution:

P(at least 10 out of 12 jurors say "guilty" | defendant is not guilty) = sum of P(k jurors say "guilty") for k = 10, 11, 12

Using the binomial formula, we can find that this probability is approximately 0.0003.

To find the probability that the jury makes the correct decision, we need to weigh the two cases by their respective probabilities:

P(correct decision) = P(defendant is guilty) * P(at least 10 out of 12 jurors say "guilty") + P(defendant is not guilty) * P(at least 10 out of 12 jurors say "guilty" | defendant is not guilty)

Plugging in the values, we get:

P(correct decision) = 0.5 * 0.952 + 0.5 * 0.0003 = 0.476

Answer:

6 sides

Step-by-step explanation:

Interior angle and exterior angle are linear pair.

Let exterior angle = x

x + 120 = 180

x = 180 - 120

x = 60

Number of sides (n) = 360 ÷ measurement of exterior angle

           n = 360 ÷ 60

n = 6

Answer:

6 sides

Step-by-step explanation:

The exterior angle and interior angle sum to 180° , then

exterior angle + 120° = 180° ( subtract 120° from both sides )

exterior angle = 60°

The sum of the exterior angles of a polygon = 360°

To find number of sides n , divide sum by measure of one exterior angle

n = 360° ÷ 60° = 6

Complete question :

A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three

Answer:

Length of first piece = x = 8

Length of second = 2x = 8*2 = 16

Length of third = 3x = 8 * 3 = 24

Step-by-step explanation:

Let :

Length of first piece = x

Length of second = 2x

Length of third = 3x

The total lengtb of board = 48 inches

Hence,

First + second + third = 48

x + 2x + 3x = 48

6x = 48

x = 48 / 6

x = 8

Length of first piece = x = 8

Length of second = 2x = 8*2 = 16

Length of third = 3x = 8 * 3 = 24

Answer:

Step-by-step explanation:

it’s the only one within Q3

The angle measures are ∠QRS = 66°  and ∠SQR = 95°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

The triangle QRS with side SR on ray ST.

∠QRS + 114° = 180°

∠QRS = 66°.

Now, the sum of all the angles of the triangle is 180°.

5y + y + 66 = 180

6y = 114

y = 19

So, ∠SQR = 95°.

Therefore, ∠QRS = 66°  and ∠SQR = 95°.

The scenario where a restaurant gathers data about a new dish by providing free samples to parties of six or more is a sampling bias.

What is sampling bias?

Sampling bias occurs when some members of a population are systematically more likely than others to be chosen for a sample. In the medical world, this is known as ascertainment bias. Because it threatens external validity, specifically population validity, sampling bias reduces the generalizability of findings.

Sampling bias occurs when some people in a community being surveyed are purposefully placed to be chosen or not chosen over others. If a sample process consistently favors some results over others, it is said to be biased. Ascertainment bias particularly in biological areas)/ and systematic bias are other terms for sampling bias. Bias can be intentional, but it is frequently unintentional.

Hence, the scenario where a restaurant gathers data about a new dish by providing free samples to parties of six or more is a sampling bias.

To differentiate F(y) = 1/ y^2 − 9 /y^4 (y + 5y^3), we need to use the quotient rule of differentiation. Your answer: F'(y) = -2y^(-3) - (12y^(-5) + 60y^(-2))(y + 5y^3)

The quotient rule states that the derivative of a quotient of functions is equal to the numerator's derivative multiplied by the denominator minus the denominator's derivative multiplied by the numerator, all divided by the denominator squared.

Using this rule, we can find the derivative of F(y) as follows:

F'(y) = [(d/dy) (1/ y^2) * (y^4(y + 5y^3)) - (d/dy) (y^4(y + 5y^3)) * (1/ y^2)] / (y^4(y + 5y^3))^2

Simplifying this expression, we get:

F'(y) = [(-2y^3(y + 5y^3))/(y^4(y + 5y^3))^2 - (y^4(1 + 15y^2))/(y^2(y^4(y + 5y^3))^2)]

= [(-2y^3(y + 5y^3)) - (y^4(1 + 15y^2))] / (y^6(y + 5y^3))^2

= (-2y^4 - 10y^6 - y^4 - 15y^6) / (y^6(y + 5y^3))^2

= (-3y^4 - 25y^6) / (y^6(y + 5y^3))^2

Therefore, the derivative of F(y) is F'(y) = (-3y^4 - 25y^6) / (y^6(y + 5y^3))^2.
To differentiate the function F(y) = 1/y^2 - 9/y^4 (y + 5y^3), you can apply the power rule and the chain rule.

Your answer: F'(y) = -2y^(-3) - (12y^(-5) + 60y^(-2))(y + 5y^3)

The sample size \((x bar)\) provides the most accurate point estimate of the genuine population mean (μ) ( if the true population mean is unknown).

Given: A study at the nearby institution using a sample of 80 students discovered that each student obtained 13.2 credit hours on average per semester.

\(x bar\) = 13.2 credits per semester, for example.

The Z algorithm is a linear-time string-matching algorithm that is used to find all occurrences of a pattern in a text. It can be implemented in various programming languages, including C++, Python, and Java. Here's an example of the Z algorithm implemented in C++:

CODE IS AS FOLLOWS:
#include <iostream>

#include <vector>

using namespace std;

vector<int> Z_algorithm(string str) {

 int n = str.size();

 vector<int> Z(n);

 Z[0] = n;

 int l = 0, r = 0;

 for (int i = 1; i < n; i++) {

   if (i > r) {

     l = r = i;

     while (r < n && str[r - l] == str[r]) r++;

     Z[i] = r - l;

     r--;

   } else {

     int k = i - l;

     if (Z[k] < r - i + 1) Z[i] = Z[k];

     else {

       l = i;

       while (r < n && str[r - l] == str[r]) r++;

       Z[i] = r - l;

       r--;

     }

   }

 }

 return Z;

}

int main() {

 string str;

 cin >> str;

 vector<int> Z = Z_algorithm(str);

 for (int i = 0; i < Z.size(); i++) cout << Z[i] << " ";

 return 0;

}

This code takes a string str as input, and returns an array Z of integers, where each Z[i] represents the length of the longest common prefix of str and str[i...n-1]. The code uses the Z algorithm to compute the Z array in linear time.

Therefore, The Z algorithm is a linear-time string-matching algorithm that is used to find all occurrences of a pattern in a text. It can be implemented in various programming languages, including C++, Python, and Java.

Null hypothesis is that the proportion of readers who owns a personal computer is equal to 0.05

∴Null hypothesis = H₀ :p = 0.05

The alternative hypothesis is that the proportion of readers who own a personal computer is not equal to 0.05

∴ Alternative hypothesis = H₁: p ≠ 0.05

Since the alternative hypothesis states that the proportion of readers who own a personal computer is different, therefore it is two tailed test.

Determine the level of significance and Critical Z- score:

Given that ,

level of significance = 0.05

since it is a two tailed test,

Z - score = 1.960 ( value in two tailed)

Since it is a two tailed test, using a Z statistics at a significance level of 5% or 0.05

We reject H₀, if Z< -1.960

             or, Z > 1.960

We reject H₀ if p ≤ α
