Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a

mean of 100 and a standard deviation of 15.

106 124

The area of the shaded region is (Round to four decimal places as needed.)

**Answer:**

The area of the shaded region is **0.2898**.

**Step-by-step explanation:**

Let *X* represent the IQ scores of adults.

It is provided that [tex]X\sim N(100,15^{2})[/tex].

Compute the probability of an adult having an IQ between 106 and 124 as follows:

[tex]P(106<X<124)=P(\frac{106-100}{15}<\frac{X-\mu}{\sigma}<\frac{124-100}{15})[/tex]

[tex]=P(0.40<Z<1.60)\\=P(Z<1.60)-P(Z<0.40)\\=0.94520-0.65542\\=0.28978\\\approx 0.2898[/tex]

*Use a *z*-table.

Thus, the area of the shaded region is **0.2898**.

What is the equation in slope-intercept form of the line that passes through the points (−12, −4) and (4, 8)?

A. y = −43 − 20

A. , y = −43 − 20

B. y = 43 − 12

B. , y = 43 − 12

C. y = −0.75 − 13

C. , y = −0.75 − 13

D. y = 0.75x +5

D. , y = 0.75x +5

**Answer:**

Choice **D**. [tex]y = 0.75\, x + 5[/tex].

**Step-by-step explanation:**

The general equation for the **slope-intercept form** of a line in a cartesian plane is [tex]y = m\, x + b[/tex], where:

Start by finding the value of [tex]m[/tex]. The slope of a line is equal to its rise-over-run. For the two points in this question:

The "rise" is the [tex]y[/tex]-coordinate of the first point minus that of the second: [tex]\text{rise} = (-4) - 8 = -12[/tex].The "run" is the [tex]x[/tex]-coordinate of the first point minus that of the second. The order of these two points should stay the same: [tex]\text{run} = (-12) - 4 = -16[/tex].Calculate the slope of this line:

[tex]\displaystyle m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{-12}{-16} = 0.75[/tex].

The equation of the line becomes:

[tex]y = \underbrace{0.75}_{m}\, x + b[/tex].

Substitute the coordinates of either of the two points to find [tex]b[/tex]. For example, for the first point [tex](12, -4)[/tex], substitute in the following:

[tex]x = -12[/tex], and[tex]y = -4[/tex].The equation becomes:

[tex]-4 = 0.75 \times (-12) + b[/tex].

Solve for the value of [tex]b[/tex]:

[tex]b = 5[/tex].

Hence, the slope-intercept form of this line shall be:

[tex]y = 0.75\, x + 5[/tex].

Which series of transformations would result in a figure that is congruent to the triangle ABC?

rotation of 180' clockwise about the origin and then dilation with a scale factor of -1, centered at the origin

rotation of 180' clockwise about the origin and then dilation with a scale factor of 2, centered at the origin

reflection across the line y ox and then dilation with a scale factor of -3, centered at the origin

translation 3 units to right and then dilation with a scale factor of 3, centered at the origin

**Answer: **rotation of 180' clockwise about the origin and then dilation with a scale factor of -1, centered at the origin

**Step-by-step explanation:**

Two triangles are congruent if all the corresponding angles are equal, and if the corresponding side lengths are equal.

Now, this means that if we have a given triangle, and we apply a dilation/contraction, then the resultant triangle will have different side lengths than the initial triangle, then those two triangles can not be congruent.

So we can already discard all the options with dilations.

Now, remember how the dilation works.

If we have a point that is at a distance L of the origin, and we do a dilation of scale factor K centered at the origin, then the new distance of the point and the origin will be K*L.

Notice that if the scale factor is equal to 1, then there is no change.

In the options, we have one where the scale factor is -1.

The minus sign means that will cause the enlargement to appear on the other side of the center of enlargement. But the scale factor still is of absolute value 1, so it will not change anything.

Then the only option that not dilates the triangle is:

Rotation of 180' clockwise about the origin and then dilation with a scale factor of -1, centered at the origin

So this is the only transformation that results in a figure congruent to the triangle ABC

2.449489743

**Step-by-step explanation:**

An airplane is flying overhead at a constant elevation of 4090 ft. A person is viewing the plane from a position 3010 ft from the base of a radio tower. The airplane is flying horizontally away from the person. If the plane is flying at the rate of 700 ft/s, at what rate is the distance between the person and the plane increasing when the plane passes over the radio tower

Answer:

415 ft/s

Step-by-step explanation:

I've attached a diagram showing the triangle formed between the plane, the person and the radio tower.

From the attached diagram, x represents the position between the person and the position on the ground directly below the airplane while s represents the distance between the person and the plane.

The constant elevation remains 4090 ft while the value of x and s varies with time.

Thus, x varies with respect to time as dx/dt while s varies with respect to time as ds/dt.

Now, we are told that the plane is flying at the rate of 700 ft/s. This means that; dx/dt = 700 ft/s

Now we want to find the rate at which the distance between the person and the plane is increasing when the plane passes over the radio tower.

This means that we want to find ds/dt when x = 3010 ft

From pythagoras theorem if x = 3010 ft and the Elevation remains 4090 ft, we can find s as;

s = √(4090² + 3010²)

s = √25788200

s ≈ 5078.21 ft

Since we want to find ds/dt at x = 3010 ft, from the diagram, we can say from pythagoras theorem that;

x² + 4090² = s²

Differentiating x and s with respect to t, we have;

2x(dx/dt) = 2s(ds/dt)

2 will cancel out to give;

x(dx/dt) = s(ds/dt)

ds/dt = (x/s)(dx/dt)

Plugging in 700 for dx/dt, 3010 for x and 5078.21 for s, we have;

ds/dt = (3010/5078.21) × 700

ds/dt ≈ 415 ft/s

Which of the pairs of events below is mutually exclusive?

Select the correct answer below:

drawing an ace of spades and then drawing another ace of spades without replacement from a standard deck of cards

drawing a 2 and drawing a 4 with replacement from a standard deck of cards

drawing a heart and then drawing a spade without replacement from a standard deck of cards

drawing a jack and then drawing a 7 without replacement from a standard deck of cards

**Answer:**

Drawing an ace of spades and then drawing another ace of spades without replacement from a standard deck of cards.

**Step-by-step explanation:**

Given four pair of events:

1. Drawing an ace of spades and then drawing another ace of spades without replacement from a standard deck of cards

2. Drawing a 2 and drawing a 4 with replacement from a standard deck of cards

3. Drawing a heart and then drawing a spade without replacement from a standard deck of cards

4. Drawing a jack and then drawing a 7 without replacement from a standard deck of cards

**To find:**

Which of the pairs is mutually exclusive?

**Solution:**

First of all, let us have a look at the definition of mutually exclusive events.

Mutually exclusive events do not have any case in common.

In other words, two events are known as mutually exclusive when both the events can not occur at the same time.

Now, let us have a look at the given options one by one:

1. Drawing an ace of spades and then drawing another ace of spades without replacement from a standard deck of cards.

We know that there is only one ace of spades in a standard deck.

**Therefore, the two events can not occur one after the other, so these are mutually exclusive events.**

2. Drawing a 2 and drawing a 4 with replacement from a standard deck of cards.

The two events can occur one after the other, so these are not mutually exclusive.

3. Drawing a heart and then drawing a spade without replacement from a standard deck of cards.

Separate cards are drawn one after the other, so not mutually exclusive.

4. Drawing a jack and then drawing a 7 without replacement from a standard deck of cards.

Separate cards are drawn one after the other, so not mutually exclusive.

Lines b and c are parallel.

What is the measure of 26?

**Answer:**

m∠6 = 54°

**Step-by-step explanation:**

**∠6 is equal to (5x + 9)** because they are **vertical angles**. But, to be able to find the measure of ∠6, you will need to find the value of (5x + 9). So, since **∠5 is equal to (13x + 9)** because they are **Corresponding Angles**, (**5x + 9) and (13x + 9) are supplementary** because they are a **linear pair**.

So:

**m**∠**6 = 5x + 9 **and

**5x + 9 + 13x + 9 = 180°**

**18x + 18 = 180**

**18x = 162**

**x = 9**

To find m∠6, plug in values:

**m**∠**6 = 5x + 9**

** = 5(9) + 9**

** = 45 + 9**

** = 54°**

6=x+23

Answer: 23+x=6

-23 -23

1x/1 -17/1

x=-17

Step-by-step explanation:

**Answer:**

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-6*x-(23)=0

Step by step explanation :

Pulling out like terms

Pull out like factors :

-6x - 23 = -1 • (6x + 23)

Solving a Single Variable Equation:

2.1 Solve : -6x-23 = 0

Add 23 to both sides of the equation :

-6x = 23

Multiply both sides of the equation by (-1) : 6x = -23

Divide both sides of the equation by 6:

x = -23/6 = -3.833

Therfor the answer is : **x = -23/6 = -3.833**

What is the equation of the line that passes through the point (-6,-7)(−6,−7) and has a slope of 0?

**Answer:**

y = -7

**Step-by-step explanation:**

The equation of a line is:

y = mx + b where m = slope

To find b, plug in a point and solve.

(-6,-7)

y = mx + b

-7 = 0(-6) + b

- 7 = 0 + b

-7 = b

So the equation is:

y = 0x + b or

y = -7

No matter what you plug into x, y = -7, because your slope is 0.

The** equation** of the line that **passes** through the **point (-6,-7)** and with **slope 0** is [tex]y=-7[/tex].

**Point **through which the given line** passes** ≡ (-6,-7)

The** slope** of the line =0

The **equation** of a **straight line** passing through the** point (x₁, y₁)** is given by: [tex]y-y_1 =m(x-x_1)[/tex]

where m is the** slope** of the line.

So, the** equation** of the line that **passes** through the **point (-6,-7)** and with **slope 0** will be:

[tex]y-(-7) = 0(x-(-7))[/tex]

[tex]y+7 =0[/tex]

[tex]y =-7[/tex]

So, the required **equation** of the line is** y=-7**.

Therefore, the** equation** of the line that** passes** through the **point (-6,-7)** and with **slope 0** is [tex]y=-7[/tex].
