√x = -7
Square root of x equals negative seven

Answer:

It has no solution within Real numbers. Its solutions are Complex/imaginary, since its discriminant is negative (-64).

Step-by-step explanation:

The normalized form of the equation

(x+2)^2= - 16

x^2 + 4x + 4 = - 16

x^2 + 4x + 20 = 0

We have in the form ax^2 + abx + c = 0

a = 1

b = 4

c = 20

Discriminant is b^2 - 4ac = 4^2 - 4*1*20 = 16 - 80 = - 64

Discriminant is negative, therefore, no Real solutions.

Answer:

(13,-10)

Step-by-step explanation:

Because it is reflecting off the X axis the X coordinate stays the same. The y coordinate will become opposite.

so for (13,-20) it would be (13,20)

and for (13,570) it would be (13,-570)

you can also look at a graph.

Answer:

\(f(x) = 2x + 5 \\ y = 2x + 5 \\ x = 2y + 5 \\ 2y = x - 5 \\ y = \frac{1}{2} x - \frac{5}{2} \\ y = {f}^{ - 1} (x) = \frac{x - 5}{2} \)

Answer:

1.5 sec by meters

Step-by-step explanation:

90 meters/60 sec=1.5

Darrel walks at a unit rate of 1.5 m/sec.

Speed is defined as the rate of change of position in unit time.

Mathematically,

Speed = Distance/Time

Now it is given that,

Distance in walk by Darrell = 90 meters

Time taken by Darell to walk 90 meters = 60 seconds

Therefore Speed i.e unit rate of walk is given as,

Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters

⇒ Unit rate of walk = 90/60 m/sec

⇒ Unit rate of walk = 3/2 m/sec

⇒ Unit rate of walk = 1.5 m/sec

Thus, Darrel walk at a unit rate of 1.5 m/sec.

The z-score of a measure X of a normally distributed variable that has mean represented by \(\mu\) and standard deviation represented by \(\sigma\) is obtained by the equation presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The mean and the standard deviation for this problem are given as follows:

\(\mu = 54.6, \sigma = 6.3\)

The z-score associated with the 25th percentile is given as follows:

Z = -0.675.

Hence Tyler's age is obtained as follows:

-0.675 = (X - 54.6)/6.3

X - 54.6 = -0.675 x 6.3

Mr. Jones bought approximately 13 pamphlets.

In this problem, we have two types of items: books and pamphlets. Books cost 50¢ and pamphlets cost 15¢ at the book sale.

Let's use variables to represent the quantities we don't know. Let's say Mr. Jones bought x books and y pamphlets.

We are given two pieces of information:
1. Mr. Jones spent $90 on his purchases.
2. He bought 15 more pamphlets than books.

Now, let's set up the equations based on the given information.

First, let's consider the cost equation. The total cost of the books and pamphlets should equal $90.

The cost of x books is 50¢ * x, and the cost of y pamphlets is 15¢ * y. So, the equation becomes:
50x + 15y = 90

Next, let's consider the second piece of information. Mr. Jones bought 15 more pamphlets than books, which means y = x + 15.

Now, we have a system of two equations:
50x + 15y = 90
y = x + 15

To solve this system, we can use substitution or elimination method. Let's use substitution:

Substitute the value of y from the second equation into the first equation:
50x + 15(x + 15) = 90

Simplify the equation:
50x + 15x + 225 = 90
65x + 225 = 90

Subtract 225 from both sides:
65x = 90 - 225
65x = -135

Divide both sides by 65:
x = -135 / 65
x ≈ -2.08

Since we cannot have a negative number of books, we know that x must be a positive whole number. So, let's round x to the nearest whole number:
x ≈ -2

Now, substitute this value of x back into the second equation to find y:
y = x + 15
y ≈ -2 + 15
y ≈ 13

Therefore, Mr. Jones bought approximately 13 pamphlets.

The probability density function for U is  {2/(1+U)³; U≥0

What is the probability?

A probability is a number that reflects how likely an event is to occur. It is expressed as a number between 0 and 1, or as a percentage between 0% and 100% in percentage notation. The higher the likelihood, the more probable the event will occur.

Here, we have

Given: The joint distribution for the length of life of two different types of components operating in a system is given by

f(y₁, y₂) = { 1/27 y₁\(e^{-(y_1+y_2)/3}\), y₁ > 0, y₂ > 0

                  0,     elsewhere, }

Let U = y₂/y₁ and Z = y₁ and y₂ = UZ

|J| = \(\left|\begin{array}{cc}1&0\\U&Z\end{array}\right|\) = Z

The joint distribution of U and Z is

f(U,Z) = 1/27 Z²\(e^{-(Z+UZ)/3}\), Z≥0, U≥0

The marginal distribution is:

f(U) = \(\frac{1}{27} \int\limits^i_0 {Z^2e^{-(Z+UZ)/3} } \, dZ\)

f(U) = 2/(1+U)³; U≥0

The probability that a randomly selected student is in music/drama is 25%

From the table, we have the following values

Music/Drama = 7 + 13 + 5 = 25

Total = (20 + 20 + 25 + 7 + 13 + 5 + 3 + 2 + 5) = 100

The probability is then calculated as:
P = Music/Drama / Total

No, because the numbers are arbitrary values between 1 and 6 and thus every roll has six (equally) possible outcomes.

What is probability in rolling a die?

A sample space is simply the collection of all potential outcomes. Simply put, you have to consider every scenario that could possibly occur. When you roll the dice, every conceivable throw will be your sample space. The likelihood of getting any side of the dice is 1/6 because there are six possible results. Rolling a 1 has a 1/6 chance of happening, a 2 has a 1/6 chance, and so on.

According to the question,

In a bag there are three different color of marbles

Number of red color marbles = 3

Number of yellow color marbles = 5

Number of blue color marbles = 8

Total number of marbles = 3 + 5 + 8

We have to find number of ways to choose 2 red, 1 yellow, and 2 blue marbles

For choosing 2 red marbles from total 3 ,

Number of ways = ³C₂

For choosing 1 yellow marbles from total 5 ,

Number of ways = ⁵C₁

For choosing 2 blue marbles from total 8 ,

Number of ways =  ⁸C₂

Total number of ways to choose 5 marbles from 16 = ¹⁶C₅

Answer:

58°

Step-by-step explanation:

Start with the equation 2x + 2 + 90 = 148

( I got the 90 from Angle B since it is a right angle.)

Combine like terms 2x + 92 = 148

( 90 and 2 didn't have variables so you could add them together.)

Subtract 92 from both sides 2x + 92 = 148

                                                      -92   -92

(The opposite of addition is subtraction.)

Now write out the new equation 2x = 56

Divide both sides by 2 \(\frac{2x}{2}\) = \(\frac{56}{2}\)

You'll end up with... x = 28

To find the measure of angle BAC, plug in 28 where the x value is 2(28) + 2

This gives you the answer 58°

The diagram that is best at displaying data dispersion is a box plot. Here's the main answer:When there is a need to compare the distribution of data, a box plot is often the best method.

A box plot is a diagram that shows how a dataset is distributed. It shows how data is spread out and helps to identify any outliers. It is most effective for comparing data sets that have a large number of data points and when the data is not normal (not evenly distributed).

A box plot is a great way to summarize large amounts of data and it is also very easy to read and interpret. It shows a number of statistical values, including the median (the middle value of the data set), the quartiles (the values that divide the data set into four equal parts) and the range (the difference between the maximum and minimum values).

Additionally, it can identify any outliers in the data, which are values that are significantly different from the rest of the data.A box plot is created by drawing a rectangle between the first and third quartiles (the middle 50% of the data) with a line drawn inside it to show the median.

Lines are then drawn from the edges of the rectangle to the minimum and maximum values. Any outliers are marked with a point outside of the rectangle.
