Answer:

Remember a key rule in dividing numbers with decimals—you need to do the same thing to both numbers in the expression. To make 15.75 a whole number, we need to multiply it by 10 twice, or, you could say, we need to multiply it by 100. That in effect moves the decimal place over two places to the right, giving us 1,575.

Step-by-step explanation:

For the given set -2≤ x ≤ 2 , x is given as integer, the solution for the given expression -2(x-5)< 10 is equal to x = 1 and x =2.

As given in the question,

Given set is equal to :

-2≤ x ≤ 2

where x belongs to integer

For the given expression -2(x-5) < 10 the solution set is equal to :

-2(x-5) < 10

Divide by -2 both the side we have,

( x -5 ) > 10 /-2

⇒ (x-5) >-5

Add 5 both the side we get,

x-5 +5 > -5 +5

⇒ x > 0

Value of x is less than or equal to 2.

x = 1 and x =2

Therefore, for the given set  -2≤ x ≤ 2 , x is given as integer, the solution for the given expression -2(x-5)< 10 is equal to x = 1 and x =2.

Answer: To determine if two known pairs of points are on the same line, you must calculate the slope of the line connecting the two points. If the slope of both pairs of points are equal, then the two points are on the same line. The formula for calculating the slope of a line connecting two points is (y2-y1)/(x2-x1).

Step-by-step explanation:

In summary:

cosθ / (secθ + tanθ) = 1 - sinθ

To verify the given identity and express cosθ / (secθ + tanθ) in terms of sinθ, we'll start by manipulating the expression using trigonometric identities.

Recall the definitions of secθ and tanθ:

secθ = 1/cosθ

tanθ = sinθ/cosθ

Substituting these values into the expression cosθ / (secθ + tanθ), we get:

cosθ / (1/cosθ + sinθ/cosθ)

Simplifying the denominator by finding a common denominator, we have:

cosθ / (1 + sinθ) / cosθ)

To divide by a fraction, we can multiply by its reciprocal:

cosθ  (cosθ / (1 + sinθ)

Multiplying the numerators, we get:

cos²θ / (1 + sinθ)

Now, using the identity cos²θ = 1 - sin²θ (the Pythagorean identity), we can substitute it into the expression:

(1 - sin²θ) / (1 + sinθ)

To simplify further, we can factor out a common factor in the numerator:

[(1 - sinθ)(1 + sinθ)] / (1 + sinθ)

Canceling out the (1 + sinθ) term, we're left with:

(1 - sinθ)

Therefore, cosθ / (secθ + tanθ) simplifies to (1 - sinθ) in terms of sinθ.

In summary:

cosθ / (secθ + tanθ) = 1 - sinθ

X is a normal distribution with mean 4 and standard deviation 8 (since the variance is 64), therefore P(X ≤ –5.2) is approximately 0.1251.

If X follows a normal distribution N(4,64), then it has a mean (μ) of 4 and a variance (σ²) of 64, with a standard deviation (σ) of 8. To find the probability P(X ≤ -5.2), we need to calculate the z-score for -5.2 and use the standard normal distribution table.
Substituting in the values, we get:
z = (-5.2 - 4) / 8
z = -1.15
Now, we can look up the probability of a standard normal distribution with a z-score of -1.15 using a table or calculator, which gives us:
P(Z ≤ -1.15) = 0.1251
Therefore, P(X ≤ –5.2) is approximately 0.1251.

As there is a greater linear relationship between the variables in the data set with an  R² value of 0.95, it is more linear. The solution given in option a, "The one with  R² = 0.95 is more linear," is correct.

In a linear regression model, the coefficient of determination, or  R², quantifies the percentage of the dependent variable's variation that is explained by the independent variable(s).

Strong linear relationships between the variables are indicated by an R² value that is close to 1, whereas weak linear relationships are indicated by a value that is close to 0.

Therefore, Because there is a stronger linear relationship between the variables in the data set with an R² value of 0.95 than in the data set with an R² value of 0.81, it is more linear.

The more closely the data points are grouped around a single line, the stronger the linear relationship, and the closer the R² number is to 1.

Therefore, We can deduce that the proper response is an option a, "The one with R²= 0.95 is more linear." Write your response in two lines.

Answer:

\(y = 1\frac{1}{4}x+7\)

Step-by-step explanation:

The equation of a straight line can be written as \(y=mx+b\).

With the pair of coordinates (coordinates are written in the form \((x,y)\) ) , the following can be written:

\(2=-4m+b\)

\(-3=-8m+b\)

To solve for a variable, we can use elimination:

\(-4m+b-(-8m+b)=2-(-3)\)  (subtract the second equation from the first)

\(-4m+b+8m-b=2+3\)

\(4m=5\) (\(b\) is eliminated)

\(m=\frac{5}{4}\)

\(=1\frac{1}{4}\)

To solve for the other variable, we can use substitution:

\(2=-4m+b\)

\(2=-4(1\frac{1}{4})+b\)

\(2 = -5 + b\)

\(b = 7\)

\(\therefore y=1\frac{1}{4}x+7\) is the linear equation for the line that passes through the points \((-4, 2)\) and \((-8,-3)\)

Answer:

x= 0.348 OR X= -1.148

Step-by-step explanation:

Given that:

2x^2+8+3x^2+4x-10

The first step is to rearrange the parameters given, by doing so, we have:

= 2x^2 +3x^2 +4x -10+8

= 5x^2 +4x - 2

The above equation forms the basis of a quadratic equation;

So using quadratic formula

= (-b +/- (√b^2-4ac))/2a

= (-4 +/- (√4^2 -4*5*(-2))/2*5

= -4 +/- (√ 16 - (-40))/10

=( -4 +/- √ 56 ) / 10

=( -4 +√ 56 ) / 10 OR =( -4 - √ 56 ) / 10

= (-4 + 7.48)/10 OR (-4 -7.48)/10

= 3.48/10 OR -11.48/10

= 0.348 OR. -1.148

SO, x= 0.348 OR X= -1.148

The correct answer is e(x) = np. The expected value for a binomial probability distribution is given by the formula e(x) = np, where n represents the number of trials and p represents the probability of success in each trial.

The expected value is a measure of the average or mean outcome of a binomial experiment. It represents the number of successful outcomes one would expect on average over a large number of trials.

The formula e(x) = np arises from the fact that the expected value of a binomial distribution is the product of the number of trials (n) and the probability of success (p) in each trial. This is because in a binomial experiment, the probability of success remains constant for each trial.

Therefore, to calculate the expected value of a binomial probability distribution, we multiply the number of trials by the probability of success in each trial, resulting in e(x) = np.

Step-by-step explanation:

The given expression "the square of a number is 3 less than four times the number" is represented as x² = 3 - 4x and the values of number could be: x1= 0.645 , x2= -4.645

In mathematics, when we refer "square of a number" we mean that the exponent of that number is 2. So we express it mathematically as:

x²

When we express "3 less than" of a number we mean that the number 3 is subtracting that number. So we express it mathematically as: 3 -

x² = 3 -

When we express "four times the number" we mean that the number is exactly 4 times greater than a number or that it contains it 4 times. So we express it mathematically as: 4x

x² = 3 - 4x

Organizing the values, we have a quadratic equation: x² + 4x – 3 = 0

Where:

Solving the quadratic question we get the values for the (x) number

x= {- b ± √ [b² - (4* a*c)]} / (2 *a)

x= {- 4 ± √ [4² - (4* 1*-3)]} / (2 * 1)

x= {- 4 ± √ (16 + 12)} / 2

x= {- 4± √ 28} / 2

x= (- 4 ± 5.29 ) / 2

x1= (- 4 + 5.29 ) / 2

x1= (1,29) / 2

x1= 0.645

x2= (- 4 - 5.29 ) / 2

x2= (9.29) / 2

x2= -4.645

We can check the values, replacing them into the equation:

(x1)² = 3 - 4(x1)

(0.645)² = 3 - 4*(0.645)

0.42 = 0.42

(x2)² = 3 - 4(x2)

(-4.645)² = 3 - 4*(-4.645)

21.58 = 21.58

Answer:

45 degrees, considering the angle as either equilateral or right would also work.

The coordinates of B, C, and D are (3,-5), (3,5), and (-7,5) respectively.

Given point A (-2,-5) and the lengths of the sides AB = 5 and BC = 10, we can use this information to determine the coordinates of B, C, and D.

Using the information provided, we know that B is 5 units away from A in the positive x-direction. Therefore, the x-coordinate of B is (-2) + 5 = 3 and the y-coordinate of B is the same as that of A, which is -5. So point B is (3,-5).

Next, we know that C is 10 units away from B in the positive y-direction. Therefore, the x-coordinate of C is the same as that of B, which is 3, and the y-coordinate of C is (-5) + 10 = 5. So point C is (3,5).

Finally, we know that D is 10 units away from C in the negative x-direction. Therefore, the x-coordinate of D is 3 - 10 = -7 and the y-coordinate of D is the same as that of C, which is 5. So point D is (-7,5).
