Answer:

x= 68.19°

Step-by-step explanation:

you can use inverse of cos(x)

\(cos^{-1}\)(\(\frac{2}{5}\)) =68.19°

∴ x=68.19°

Answer:

we can find the value of x using cos.

cos=adjacent side/hypotenuse

\(cos(x)=2/5\\\)

Using inverse cos, we can find the value of x

\(cos^-1(2/5)=66.42182152\\x=66\)

Step-by-step explanation:

The value of q is -27.

Recall Vieta's Formulas, which state that for a quadratic equation \(ax^2\) + bx + c = 0 with zeroes alpha and beta, the sum of the zeroes is equal to -b/a, and the product of the zeroes is equal to c/a.

In our equation \(x^2\) - 3x + q, the sum of the zeroes alpha and beta is -(-3)/1 = 3.

We are given that 2 alpha + 3 beta = 15. Substitute alpha = (15 - 3 beta)/2 into the equation.

Replace the value of alpha in the sum of zeroes equation: (15 - 3 beta)/2 + beta = 3.

Simplify the equation by multiplying both sides by 2: 15 - 3 beta + 2 beta = 6.

Combine like terms: 15 - beta = 6.

Subtract 15 from both sides: -beta = -9.

Multiply both sides by -1 to solve for beta: beta = 9.

Substitute the value of beta into the sum of zeroes equation: alpha = (15 - 3 * 9)/2 = -3.

Since we have the values of alpha and beta, we can find q using the product of the zeroes formula: q = alpha * beta = -3 * 9 = -27.

Question 24: A data visualization tool that updates in real time and gives multiple outputs is called - a data dashboard.

A data visualization tool that updates in real time and gives multiple outputs is called a data dashboard. What is a scatter plot? A scatter plot is a type of diagram used to display two variables on a two-dimensional plot. The positioning of data points on a scatter plot graphically depicts the correlation between the two variables. To construct a scatter plot, two variables (independent and dependent variables) are plotted on a graph.

The independent variable is plotted on the horizontal (x) axis and the dependent variable is plotted on the vertical (y) axis. A point is plotted for each pair of values, and the pattern of the points suggests a relationship between the two variables.A scatter plot is useful in displaying the correlation between two variables. The correlation is positive if the points are in an upward direction. The correlation is negative if the points are in a downward direction. A lack of correlation, or random points, is suggested by a scatter plot with no apparent pattern.

The surface area of the cylindrical gift box is 24πx² + 72xπ + 54π.

The radius of a cylindrical gift box is (2x + 3) inches. The height of the gift box is twice the radius.

Therefore, the surface area of the cylinder can be found as follows:

Hence,

surface area of the cylindrical gift box = 2πr(r + h)

where

Therefore,

r = 2x + 3

h = 2(2x + 3) = 4x + 6

Hence,

surface area of the cylindrical gift box = 2 × π × 2x + 3((2x + 3) + 4x + 6)

surface area of the cylindrical gift box = 2π(2x + 3)(6x + 9)

surface area of the cylindrical gift box = 2π(12x² + 18x + 18x + 27)

surface area of the cylindrical gift box = 2π(12x² + 36x + 27)

surface area of the cylindrical gift box = 24πx² + 72xπ + 54π

For independent events, P(B | A) = P(B). For independent events, the occurrence of event A does not affect the probability of event B occurring.

Therefore, the conditional probability of event B given event A, denoted as P(B | A), is equal to the probability of event B, denoted as P(B). This can be mathematically expressed as:

P(B | A) = P(B)

In other words, if A and B are independent events, knowing that event A has occurred does not provide any additional information about the probability of event B occurring. The probability of event B occurring remains the same whether or not event A has occurred.

This property of independence is a fundamental concept in probability theory and is used in many real-world applications, such as in calculating the likelihood of multiple events occurring together, predicting the outcomes of games and sports, and analyzing financial risks.

Answer:

the solution to the inequality -2.4(x-6)>52.8 is A

The given graph in option A is representing the solution of the given inequality -2.4(x-6) > 52.8.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

Given inequality is:-

We will put the value of endpoints in the graph first and put the value of x = -16

-2.4  (  x  -  6   )   >  52.8

-2.4  (  -16  -  6 )  >  52.8

-2.4  (  -22  )    >   52.8

52.8   =  52.8

Now put the value of x =-18

-2.4(  -18  -  6 )  >  52.8

-2.4( -24 )  >  52.8

57.6   >    52.8

Therefore the given graph in option A is representing the solution of the given inequality -2.4(x-6) > 52.8.

Good luck on your assignment..

Answer:

-114

Step-by-step explanation:

To find f(6), you need to plug in the value in parentheses wherever there is an x in the equation.

f(x) = -4x + 5x

f(6) = -4(6) + 5(6)

f(6) = -4(36) + 30

f(6) = -144 + 30

f(6) = -114

Answer:

The answer is

C. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.

Step-by-step explanation:

In mathematics, mapping is used synonymously to a function, and a function is basically a relation between two values or expressions say y and x

like the difference equation relating y and x.

In a function, for every value of x plugged into the function there is always a corresponding value of y.

Example.

Given the function

y=2x+5.

find the value of y when x=0

we are going to substitute x=0 and solve

y=2(0)+5

y=5

so for x=0 y=5

The sample mean and sample standard deviation provide valuable information about a set of data, but they should be used with caution when making inferences about the population. It is important to use statistical methods to determine the reliability of these estimates and to account for sources of variability in the data.

Firstly, the sample mean is a measure of central tendency that represents the average value of a set of data. In this case, the sample mean of 290 rooms occupied per day is the sum of the number of rooms occupied each day over the 25-day period divided by the total number of days. It is important to note that the sample mean is only representative of the specific sample of 25 days and may not accurately reflect the population mean.

Secondly, the sample standard deviation is a measure of dispersion that indicates how spread out the data is from the mean. A smaller standard deviation means that the data points are closer to the mean, while a larger standard deviation means that the data points are more spread out. In this case, the sample standard deviation of 20 rooms indicates that there is some variability in the number of rooms occupied each day.
