Answer:  The correct answer is x = 19 / 5

Step-by-step explanation:

Solve the equation

5x + 3 = 22

Subtract 3 from both sides

5x + 3 − 3 = 22 − 3

5x = 19

Divide both sides by 5

5x/5 = 19/5

x = 19 / 5

The expression is - 2xz⁴

An exponent is a method of expressing large numbers in terms of power. So, exponent means how many times a number is multiplied by itself. For example, 5 is multiplied by itself 3 times i,e 5 *5*5. It can be written as 5³.

Here, 3 is the exponent, and 5 is the base. We can read it as 5 is raised to power 3. The symbol '^' is used to represent the exponents. It is called a carrot.

Step-by-step explanation:

All of these answer choices are in slope intercept form:

[tex]y=mx+b[/tex]

where [tex]m[/tex] is the line's slope and [tex]b[/tex] is its y-intercept.

First, we'll find the line's slope using the points [tex](-3,4)[/tex] and [tex](0, 2)[/tex].

[tex]m=\dfrac{\textrm{rise}}{\textrm{run}} = \dfrac{2-4}{0-(-3)} = \dfrac{-2}{3}[/tex]

Then, plug that [tex]m[/tex]-value into the slope intercept form equation:

[tex]y = \dfrac{-3}{2} + b[/tex]

Next, find the y-value at which the line crosses the y-axis:

[tex]b=2[/tex]

Finally, plug that [tex]b[/tex]-value into the slope intercept form equation and look at which answer choice the equation we solved for matches.

Answer:

(4x^2 +7x + 2)

Step-by-step explanation:

(8x³ +26x² + 25x + 6)/( 2x + 3)

(8x³ +26x² + 25x + 6) = (4x^2 +7x + 2)(2x + 3)

(4x^2 +7x + 2)(2x + 3)/(2x+3) = (4x^2 +7x + 2)

On the 19th day, the lily pad covered half the pond.

The reason behind this is, If the lily pad doubles in size every day, then on the 20th day it will be twice as large as it was on the 19th day. That means it was already covering half the pond on the 19th day.

In this puzzle, the water lily is described as doubling in size every day. This means that on the first day, the lily pad is small, but by the second day, it has doubled in size. On the third day, it doubled in size again, and so on. By the 20th day, the lily pad has grown so large that it covers the entire pond.

The solutions to the quadratic equation 8x² - 3x = 5 are x = 1 and x = -5/8

From the question, we have the following parameters that can be used in our computation:

8 x squared - 3 x = 5

Express properly

So, we have

8x² - 3x = 5

This gives

8x² - 3x - 5 = 0

The quadratic formula is represented as

x = (-b ± √[b² - 4ac])/2a

Substitute the known values in the above equation, so, we have the following representation

x = (3 ± √[(-3)² - 4 * 8 * -5])/(2 * 8)

Evaluate

x = (3 ± √169)/16

So, we have

x = (3 ± 13)/16

To the nearest of tenth hour kwan has driven total 234 miles.

Speed is the pace at which an object's position changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Speed= distance/time

Based on his speed and the distance driven within that time, Kwan will have driven 234 miles

First find out Kwan's speed per hour:

Speed = Distance / Time

Convert the time to decimals:

= 1 + 1/10 hours

= 1 + 0.1

= 1.1 hours

Speed:

= 234 / 1.1

= 212 miles per hour

A permutation is a mathematical way of an arrangement of objects in a particular way or order. We have, there is total 20 people at chess club on a particular day. Now, these 20 people divided into two groups each find opponents and start playing. There are 10 games in total. Let's say the first player in line plays with the white pieces in the first game. The second person in line plays with the black pieces in the first game. The third person plays with the white pieces in game two. The fourth person plays with the black pieces in game two, and so on. There are 20 of them! ways to do it. But we have to remember that the order of the games doesn't matter, so we have to divide this number by 10! , i.e, number of game permutations . Therefore, the total number of possible arrangement is,

If the null hypothesis is true in a chi-squared test, then we expect the test statistic to be approximately equal to its expected value.

In a chi-squared test, the null hypothesis is the statement that there is no significant association between two variables. If the null hypothesis is true, then we expect the test statistic to be approximately equal to its expected value. The expected value is calculated using the degrees of freedom and the expected frequency of each category in the contingency table.

The chi-squared test statistic is calculated by subtracting the observed frequency from the expected frequency for each category and then squaring the result. These squared differences are then summed across all categories to calculate the chi-squared test statistic.

If the null hypothesis is true, we expect the test statistic to be close to its expected value. This is because when the null hypothesis is true, the observed frequencies should be close to the expected frequencies. Therefore, the squared differences should be small, resulting in a small test statistic.

A continuous quantitative variable is a measure of a quantity that can take any value within a certain range. An example of this is the number of gallons of paint purchased.

A continuous quantitative variable is a type of data that is measured on a continuous scale. This type of data is typically used to measure quantities that can take any value within a certain range. Examples of continuous quantitative variables include the number of gallons of paint purchased, the number of miles of interstate highways, or the population of a city. Continuous quantitative variables differ from discrete quantitative variables, which are used to measure counts of items or events. For example, the number of quarts of milk purchased or the number of times you sharpen your pencil while working on statistics problems would be discrete quantitative variables. Continuous quantitative variables can be measured with precise accuracy, while discrete quantitative variables can only be measured in whole numbers, since they are counts of items or events.

We will discover that the probability that you will at random wind up with an orange hat is as follows: P = 1/12

Observe how we arrived at that now:

The color of only one item of clothing will change. The likelihood that you will receive an orange hat is what we are looking for.

We must first determine the likelihood that you will choose a hat at random. The likelihood of picking your hat at random is if all the apparel has the same probability of being chosen, just one more than the number of options (4). p = 1/4

The color is now chosen at random using the same methodology as before, with the likelihood that orange will be chosen at random being: q = 1/3.

The scores are: 5,4,66,70,71,75,77,80,84,85,87,90,93,95 and 96.

A percentile is a value on a scale of one hundred that indicates the percent of a distribution that is equal to or below it.

The percentile rank of a score of 71 on the test is find by formula.

[tex]R_{100} =\frac{100(N < )+\frac{1}{2}N }{N}[/tex]

Answer:

L = 12ft

W = 13ft

Step-by-step explanation:

Let's use the two pieces of information to make 2 equations (we need 2 eqns to solve for 2 variables: Length and Width).

The length and width are consecutive integers

L+1=W

The area of the rectangle is 156 square feet.

L*W=156

We know that W=L+1 from our first equation, so substituting that information into our second equation we get

L*(L+1)=156

Let's distribute that L

L^2 + L = 156

and subtract 156 from both sides

L^2 + L - 156 = 0

Now we can use the quadratic formula to find L. L cannot be negative, so

L = 12

using our very first equation we know L, so we can solve for W.

L+1=W

12+1=W

W = 13

The equation of the line passing through (3, 4) and perpendicular to the line  y=1/9x + 8 in slope-intercept form is y = -9x + 31

Suppose we have two lines with slope m₁ and m₂ respectively, then those lines are perpendicular to each other if

m₁ x m₂ = -1

In the given problem, the line is perpendicular to a line whose equation is:

y = 1/9 x + 8

Hence,

m₁ x m₂ = -1

1/9 x  m₂ = -1

m₂ = -9

Therefore, the equation of the second line is:

y = -9x + b

To find the value of b, we use the fact that the line passing through (3,4)

Substitute x = 3, and y = 4

4 = -9 (3) + b

b = 4 + 27 = 31

Thus, the equation of the line is:

y = -9x + 31
