The proportion of observations in a standard Normal distribution that satisfies each of the given statements are:

1) P(z > -1.66) = 0.95154

2) P(-1.66 < z <2.85​) = 0.94936

Z table or z-score table is defined as a mathematical table that provides the values of cumulative density function for standard normal variates. It is used to determine the probability of a standard normal variate lying in a given interval.

We have to find the proportion of observations from a standard normal distribution that has a z-score between -1.66 and 2.85.

1) z > -1.66

From normal probability distribution table, we have that:

P(z > -1.66) = 0.95154

2) -1.66 < z <2.85​

From normal probability distribution table, we have that:

P(-1.66 < z <2.85​) = 0.94936

The process to find the scale factor of a shape and the concept of sequence of transformations is explained below.

In order to find the scale factor of a shape, we need to compare the corresponding side lengths of the original shape to the corresponding side lengths of the new shape after a dilation.

The scale factor is the ratio of any two corresponding side lengths.

The sequence of transformations is defined as the order in which different transformations are applied to a shape.

For example, if we have a triangle and we first translate it, then rotate it, and then dilate it, the sequence of transformations would be : translate → rotate → dilate.

The solution of the given system of equations is x = -1 and y = 4.

The given system of equations is 4x + 8y = 40 and 6x + 3y = 6.

To solve this system of equations, we need to use elimination method. We can subtract 6x from both sides of the second equation and subtract 4x from both sides of the first equation. We get:

8y = 40 - 4x and 3y = 6 - 6x

We can now divide both sides of the second equation by 3 to obtain y = 2 - 2x.

We can substitute the value of y from the second equation into the first equation to get 4x + 8(2 - 2x) = 40, which simplifies to -8x = 8. We can solve this equation for x by dividing both sides by -8, resulting in x = -1.

Substituting the value of x into either equation, we can obtain y = 4. So, the solution of the given system of equations is x = -1 and y = 4.

Answer: Using the given functions, we can model the distance, d(t), that the car is from the city as:

d(t) = f(t) + g(t) = 10 + 65t

So, after 2 hours of driving, the distance that the car has traveled from the city is:

d(2) = 10 + 65(2) = 10 + 130 = 140 miles

Therefore, Riordan is incorrect, and the correct distance the car is from the city after 2 hours of driving is 140 miles.

Step-by-step explanation:

The polynomial f(x) of degree 3 with real coefficients and the given zeros is f(x) = x³ - x² + 4x + 2.

To find a polynomial f(x) of degree 3 with real coefficients and the given zeros, we need to use the fact that if a polynomial has a complex root, then its conjugate is also a root. This means that if 1-i is a root, then 1+i is also a root.

So, our polynomial f(x) has the following roots: -1, 1-i, 1+i.

We can write the polynomial as the product of its factors:

f(x) = (x - (-1))(x - (1-i))(x - (1+i))

Simplifying the factors:

f(x) = (x + 1)(x - 1 + i)(x - 1 - i)

Multiplying the factors:

f(x) = (x + 1)(x² - 2x + 2)

Expanding the polynomial:

f(x) = x³ - 2x² + 2x + x² - 2x + 2

Simplifying the polynomial:

f(x) = x³ - x² + 4x + 2

So the slope-intercept form of the equation of the line passing through the two given points is:

y = -5x + 26

If an equation is expressed in the form y=mx+b, where m denotes the slope and b the y-intercept, it is said to be linear.

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

To find the slope of the line passing through the two given points (5,1) and (2,16), we can use the formula:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) = (5,1) and (x2, y2) = (2,16)

m = (16 - 1)/(2 - 5) = -5

So the slope of the line is -5.

To find the y-intercept b, we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Using the point (5,1) and the slope m = -5, we get:

y - 1 = -5(x - 5)

Simplifying this equation, we get:

y = -5x + 26

So the slope-intercept form of the equation of the line passing through the two given points is:

the height of the antenna is approximately 24 meters.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

From the diagram, we see that we need to find the distance d and the height h. We can use the tangent function to find these values.

First, let's find d:

tan(θ) = h / (d + 1.51)

Rearranging, we get:

d = (h / tan(θ)) - 1.51

Next, let's find h:

tan(θ') = h / d

Substituting the expression for d that we found above, we get:

tan(θ') = h / ((h / tan(θ)) - 1.51)

Multiplying both sides by (h/tan(θ1)) - 1.51 and simplifying, we get:

h = (29 * tan(θ') * tan(θ)) / (tan(θ') - tan(θ))

Now we can plug in the values for the angles and solve for h:

h = (29 * tan(31°) * tan(17°)) / (tan(31°) - tan(17°))

h ≈ 24

So the height of the antenna is approximately 24 meters.

The set of vectors {v1, v2, v3} is linearly dependent for all real number h ≠ 4 and all real number h ≠ -4.

The set of vectors {v1, v2, v3} is linearly dependent if there exists a set of real numbers a, b, and c such that a*v1 + b*v2 + c*v3 = 0 and at least one of a, b, or c is not equal to zero. In this case, we can write the equation as:

a*1 + b*2 + c*(-1) = 0

We can rearrange this equation to solve for h:

h = -a - 2*b + c

Now we can plug in the values for v1, v2, and v3:

h = -1 - 2*2 + (-1)*(-1)

h = -4

Therefore, the set of vectors {v1, v2, v3} is linearly dependent when h = -4.

Alternatively, we can also use the determinant of the matrix formed by the vectors to determine when the set is linearly dependent. The determinant of the matrix is given by:

| 1 2 -1 |
| -1 1 3 | = (1)(1)(h) + (2)(3)(-1) + (-1)(-1)(2) - (-1)(1)(-1) - (2)(-1)(1) - (1)(3)(2)
| 2 1 h |

Simplifying this equation gives:

h - 6 - 2 + 1 + 2 - 6 = 0

h - 11 = 0

h = 11

Therefore, the set of vectors {v1, v2, v3} is also linearly dependent when h = 11.

So the set of vectors {v1, v2, v3} is linearly dependent for all real number h ≠ 4 and all real number h ≠ -4.
