The solution of the quadratic equation is x = 2. Therefore, \(\frac{4+\sqrt{-4^{2}-4(1)(4) } }{2(1)}\)  or \(\frac{4-\sqrt{-4^{2}-4(1)(4) } }{2(1)}\)

The quadratic formula can be use to solve the quadratic equation as follows:

x² - 4x + 4 = 0

Modelling it to quadratic equation, ax² + bx + c

Hence,

using quadratic formula,

\(\frac{-b+\sqrt{b^{2}-4ac } }{2a}\) or \(\frac{-b-\sqrt{b^{2}-4ac } }{2a}\)

where

Hence,

a = 1

b = -4

c = 4

Therefore,

\(\frac{4+\sqrt{-4^{2}-4(1)(4) } }{2(1)}\) or \(\frac{4-\sqrt{-4^{2}-4(1)(4) } }{2(1)}\)

Finally

x = 2

Answer:

If you owe your friend 10 dollars that would be -10 on a number line and then you borrow 5 dollars which means you owe that money too and you would continue to move left on the number line 5 spaces.

Step-by-step explanation:

it would be beneficial to analyze other variables such as gender and opinion on the topic for a more comprehensive understanding of the local political opinion.

If the standard deviation of the ages is zero, then all individuals in the sample must have the same age of 25 years old. This means that the sample is not diverse and may not be representative of the entire neighborhood's opinion on the political topic. Therefore, conclusions drawn from this sample may not accurately reflect the opinions of the entire population. It is important to ensure that the sample is diverse and representative to make valid conclusions about a sensitive political topic.
Based on the data you collected, which includes age, gender, and opinion on the local sensitive political topic, you calculated the average age to be 25 years old and the standard deviation of the ages to be zero years old. This means that all individuals in your neighborhood are exactly 25 years old. Since there is no variation in age, it would be beneficial to analyze other variables such as gender and opinion on the topic for a more comprehensive understanding of the local political opinion.

The row vectors of the matrix are [-2 -3 1 0], and the column vectors are:

In a matrix, row vectors are the elements listed horizontally in a single row, while column vectors are the elements listed vertically in a single column. In this case, the given matrix is a 1x4 matrix, meaning it has 1 row and 4 columns. The row vector is [-2 -3 1 0], which represents the elements in the single row of the matrix. The column vectors, on the other hand, can be obtained by listing the elements vertically. Therefore, the column vectors for this matrix are -2, -3, 1, and 0, each listed in a separate column.

Answer:

5=18

Step-by-step explanation:

they are counting by 2s      10,12,14,16,18

Hope this helps!

Answer:

18

Step-by-step explanation:

It seems like for this pattern, as the x-value(base value) increases, the corresponding y-value(value changing with the base value) increases by 2 given that the function starts with a y-intercept of 8. So at the value 0, the corresponding number would be 8. So in this case, by creating a function regrading this information we can solve for the corresoponding value of 5: y = 2x + 8

y = 2 * 5 + 8

y = 10 + 8

y = 18

5 = 18

Another way to approach this is just by following the pattern given to us in the description. We see that the pattern starts at 10, and increases by 2 for each increasing base value. Therefore, if 4 = 16, then 16 + 2 = 5, so 5 = 18.

The number of persons that would be able to receive the chocolates based on the question is 19

The total number of chocolate = 6 1/2

This can be written to be 13 / 2 or 6.5

The number or amount that she has to give from what is contained in the box to each person is 1/3 = 0.33

Hence to get the number of people that would receive the chocolate we would have

6.5 / 0.33

= 19.5

This can be approximated to 19

Hence the total number that would receive the chocolate is 19

The proportion of rent that the friend with the smaller bedroom has to pay is 125/265. So his share of the rent is $540.35.

Suppose the distance from your house to your school is 2 miles, while the distance from your house to the nearest park is 3 miles.

Then we say that the ratio of the two distances s 2:3. To take another example suppose in today's hw, you have got 10 questions to answer, while in yesterday's hw you had 7 questions to answer. In this case we say that the ratio of the no of hw questions you have today, to the no questions you had yesterday is 10:7.

A ratio is a pair of numbers which gives the relative magnitudes of two similar quantities. A ratio of a:b is also represented by the fraction a/b.

Let us use the previous example. the ratio of the distances from your home to your school and to the nearest park is say 2:3 . Now consider the ratio of the time it takes to reach your school from your home by car to the time it takes to reach the park by car from your home. suppose this ratio a:b . Then it reasonable to assume that the two fractions a/b and 2/3 are equal, assuming the car moves at the same average speed.

This common ratio is called the proportion. we write it as follows,dist to school : dist to park : : time to school : time to park.

This is read as the distance to school IS TO distance to park AS time to school IS TO time to park.

if we write the ratios as fractions. Then they are proportional or equivalently they are the same proportion if and only if the two fractions are equal.

So The ratio of the bedroom sizes is 125 : 140.

Total rent that is to be divided between them is $1150.

if the share of the rents are a,b. then as fractions a/b = 125/140

So. a/a+b = 125/125+140 = 125/265

but a + b = 1150

So a = 125/265 (1150) = 542.452

The closest option is $540.35. So this is our answer.

The square mil area for a 2 inch wide by 1/4 inch thick copper busbar is 500 square mils.

To find the square mil area for a 2 inch wide by 1/4 inch thick copper busbar, we need to multiply the width and thickness of the busbar in mils.

1 inch = 1000 mils

So, the width of the busbar in mils = 2 inches x 1000 mils/inch = 2000 mils

And, the thickness of the busbar in mils = 1/4 inch x 1000 mils/inch = 250 mils

Therefore, the square mil area of the copper busbar = width x thickness = 2000 mils x 250 mils = 500,000 square mils.

Hence, the square mil area for a 2 inch wide by 1/4 inch thick copper busbar is 500,000 square mils.

According to Benford's law, 5 will be the first digit of a random number set is d. less often than 4.

According to Benford's law, which is an empirical law about the frequency distribution of leading digits in many real-life collections of numerical data, the digit 5 is actually the second least frequent leading digit after 1 and is less common than 4 as a first digit. In actuality,

Benford's rule states that the likelihood of a number having four as its first digit is nearly thirty percent, whereas the likelihood of a number having 5 as its first digit is approximately 25%. This is due to the fact that numbers with smaller starting digits are more common than those with bigger leading digits in many naturally occurring datasets.

The probability that a CD will last less than 3 years is approximately 86.65%.

The probability can be determined using the standard normal distribution. Given that the CD's lifespan follows a normal distribution with a mean of 4 years and a standard deviation of 0.8 years, we need to find the z-score for 3 years. The z-score formula is calculated as (x - μ) / σ, where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

For 3 years, the z-score is (3 - 4) / 0.8 = -1.25. Using a standard normal distribution table or a calculator, we can find that the probability corresponding to a z-score of -1.25 is approximately 0.1056 or 10.56%.
