suppose that you have 15 quarters, 10 dimes, 10 nickels, and 10 pennies in your pocket. you reach in and choose a coin at random so that you can give it to your child. what is the expectation? (round your answer to two decimal places.)

### Answers

If you have 15 quarters, 10 dimes, 10 nickels and 10 pennies, then the **probabilities** of getting quarter, dimes, nickels and pennies are 0.33, 0.22, 0.22 and 0.22 respectively.

**Total number** of quarters = 15 quarters

Total number of dimes = 10 dimes

Total number of nickels = 10 nickels

Total number of pennies = 10 pennies

Total number of coins = 15+10+10+10 = 45

The probability of getting a **quarters **= 15/45

= 0.33

The probability of getting a **dimes **= 10/45

= 0.22

The probability of getting a** nickel =** 10/45

= 0.22

The probability of getting **penny** = 10/45

= 0.22

Hence, if you have 15 quarters, 10 dimes, 10 nickels and 10 pennies, then the probabilities of getting quarter, dimes, nickels and pennies are 0.33, 0.22, 0.22 and 0.22 respectively.

Un árbol que mide 22 metros de altura está creciendo a un ángulo de 83° con respecto al suelo (ver la figura siguiente). Miranda se para a cierta distancia de la base del árbol, se da cuenta que el ángulo de elevación desde el suelo hasta la parte alta del árbol es 32°. ¿A qué distancia está ella de la base del árbol? Redondear la respuesta a la décima más cercana de un metro.

### Answers

**Answer: ≈37.8 m**

**Step-by-step explanation:**

The sum of the angles of a triangle is equal to 180°.

⇒ х+32°+83°=180°

х+115°=180°

x+115°-115°=180°-115°

x=65°

The sine theorem goes like this: the sides of a triangle are proportional to the sines of the opposing angles.

[tex]\displaystyle\\\frac{22}{sin32^0} =\frac{S}{sin65^0} \\\\Multiply\ both \ parts\ of \ the \ equation\ by\ sin65^0:\\\\S=\frac{22(sin65^0)}{sin32^0} \\\\S\approx\frac{22(0.91)}{0.53}\\\\ S\approx37.8 \ m[/tex]

A person driving her car at 12.5 m/s approaches an intersection just as the traffic light turns yellow. She knows that the yellow light lasts only 2.0 s before turning red, and she is 28 m away from the beginning of the intersection, which is 15 m wide, as shown below. Using the gas pedal she can accelerate at 3.5 m/s2 and using the brake pedal she can accelerate at –5.8 m/s2. Ignoring reaction time and car length, determine whether she should try to stop or speed up to be a legal driver.

### Answers

She should try to **stop the car.**

We will discuss the possibilities of trying **to stop** and trying **to speed up **in 2s and find the distance she travels to get into a conclusion.

If she try **to stop**, then the **acceleration,** a = -5.8 m/s²

Initial **velocity**, v₀ = 12.5 m/s

Final velocity, v₁ = 0 m/s [Since the car is stopped]

Let **d **be the **distance** the car travels before stopping.

Then, we have, v₁² = v₀² + 2ad

Therefore, d = v₁²-v₀²/2a

= 0-(12.5)²/2 x (-5.8)

= 156.25/11.6

= 13.47 m

So she can **stop** in time as she is 28m far from the beginning of the intersection.

If she try **to speed up, **then the **acceleration** of the car, a = 3.5 m/s²

Initial **velocity** of the car, v₀ = 12.5 m/s

Time she have, t = 2 s

Let** d **be the** distance** the car travels in 2 s.

Then, d = v₀t +(1/2)at²

= 12.5 x 2 + (1/2) x 3.5 x 2²

= 25 + 7

= 32 m

She is 28 m before the beginning of the intersection which is 15 m wide. So if she speed up she will be in the middle of the intersection when the light turns red and may have to stop.

Hence as a legal driver, she should try **to stop the car**.

suppose a snowball remains spherical while it melts, with the radius r shrinking at 2 inch(es) per hour. what is the rate of change of the surface area s when the radius is 4?

### Answers

When the radius of the snowball is 4 and shrinks at a rate of 2 inches per hour then the rate of change of the **surface area** s is equal to **64π in²/hr**

As the** radius** r is shrinking at the rate of two inches per hour, it can be represented as;

dr/dt = -2 in / hr

Here, the negative sign represents the shrinking of the snowball with time t.

The surface area of a sphere can be represented by the formula;

S = 4πr²

Now we differentiate S with respect to t by keeping radius (r) as a variable as follows;

dS/dt = d/dt (4πr²)

dS/dt = 4π (d/dt) (r²)

dS/dt = 4π × 2r (dr/dt)

Putting the value of r = 4 and calculated value of dr/dt = -2 in the equation as follows;

dS/dt = 4π × 2(4)(-2)

dS/dt = -64π

Therefore, the **rate** of change of surface area s is calculated to be 64π in²/hr.

The unknown measures of the **right angle triangle** are m∠V = 69° , RV = 12.85 and m∠R = 21°

How to find the angles and side of a right triangle?

A** right triangle** is a triangle that has one of its angles as 90 degrees.

Therefore, the side and angles of a **right triangle** can be found using trigonometric ratios.

Hence,

**tan v = opposite / adjacent**

opposite side = 12

adjacent side = 4.6

Therefore,

tan V = 12 / 4.6

v = tan⁻¹ 2.60869565217

v = 69.0265065627

**m∠V = 69°**

Let's find m∠R

m∠R = 180 - 69 - 90

**m∠R = 21°**

Let's find RV

sin 69° = opposite / hypotenuse

sin 69 = 12 / h

cross multiply

h = 12 / sin 69

h = 12 / 0.93358042649

h = 12.8537402885

**RV = 12.85 units**

Golfer Lexi Thompson is one of the top golfers on the LPGA tour. The distribution of scores for each of

the more than 700 rounds over her LPGA career is approximately normal with a mean of about u= 70.6

strokes and a standard deviation of about o= 3.2 strokes.

Use the empirical rule to answer the following questions.

What percent of Thompson's Scores are greater than 73.8?

What percent of Thompson's scores are between 64.2 and 67.4

### Answers

The **percent** of Thompson's Scores that are greater than 73.8 is **95%**

The **percent** of Thompson's Scores that are between 64.2 and 67.4 is **69% to 94%**

How to find what percent of Thompson's Scores are greater than 73.8

given data

a mean of about 70.6 strokes

a standard deviation of about 3.2 strokes

Applying the **68%, 95%, **and** 99.7% Rule**. This rule says that standard deviations is changed to percentages when:

68% of scores fall within 1 Standard Deviation of the mean.95% of all scores fall within 2 Standard Deviation of the mean.99.7% of all scores fall within 3 Standard Deviation of the mean.

Hence we calculate how many standard Deviations that gives 73.8 as follows

mean ± standard deviation

since the73.8 is greater than the mean we add the SD to the mean

70.6 + 3.2 = 73.8

73.8 is 1 SD but we are looking for value greater than 73.8. This should be just above 73.8, hence from 2 SD which is **95%**

What percent of Thompson's scores are between 64.2 and 67.4

Applying the **68%, 95%,** and **99.7% Rule**

mean ± standard deviation

The numbers asked is less than the mean hence we subtract

70.6 - 3.2 = 67.4 ( 1 SD = 68% )

70.6 - 3.2 - 3.2 = 64.2 ( 2 SD = 95% )

The question asks the percent of Thompson's scores **between** 68% and 95%. This is **69% to 94%**.

-1 is the x and -10 is the y.

In the point (5,2)

5 is the x and 2 is the y.

[tex]\frac{2- -10)}{5 - -1)}[/tex] Subtracting a negative is the same as adding a positive.

[tex]\frac{2+ 10}{5+1}[/tex] = [tex]\frac{12}{6}[/tex] = 2

We know know the slope. We will use the form

y - [tex]y_{1}[/tex] = m (x-[tex]x_{1}[/tex]) we will plug in the numbers that we know.

**If we use point (-1, -10)**

y -- -10 = 2(x - -1)

**y + 10 = 2( x+1)**

**If we use the point (5,2)**

**y -2 = 2(x -5)**

A **rectangular solid** has a length (l), height (h), and width (w). The **diagonal** of the **rectangular solid**, d, can be calculated using the given formula below:

**Diagonal** of **rectangular solid** (d) = √(l² + w² + h²).

Given the following dimensions of the **rectangular box:**

Length of the **rectangular box** = 8 unitsWidth of the **rectangular box** = 4 unitsHeight of the **rectangular box** = 2

Substitute l = 8, w = 4,a nd h = 2 into the **equation** d = √(l² + w² + h²):

**Diagonal** of **rectangular solid** (d) = √(8² + 4² + 2²)

**Diagonal** of **rectangular solid** (d) = √(64 + 16 + 4)

**Diagonal** of **rectangular solid** (d) = √84

Simplify √84 further

**Diagonal** of **rectangular solid** (d) = √(4 × 21)

**Diagonal** of **rectangular solid** (d) = 2√21 units

Therefore, the **rectangular solid** has a diagonal that is: 2√21

Find the remainder when 4x3 +6x2 −8x − 2 is divided by each of the

following:

x−1 x−2

x−3 x+1

x+2 x+3

### Answers

Using the **remainder theorem**, the remainder of the divisions of p(x) = 4x³ + 6x² - 8x - 2 by the polynomials are given as follows:

x - 1: 0.x - 2: 38.x - 3: 136.x + 1: 8x + 2: 6x + 3: -32.

What is the remainder theorem?

Suppose that we have a polynomial p(x), that is divided by a linear term x - a, the **remainder **is given by the numeric value of p(x) at x = a, that is, **p(a).**

For this problem, the **polynomial **is given as follows:

p(x) = 4x³ + 6x² - 8x - 2.

Then the **remainder **for each division is given as follows:

x - 1: a = 1, p(a) = 4(1)³ + 6(1)² - 8(1) - 2 = 0.x - 2: a = 2, p(a) = 4(2)³ + 6(2)² - 8(2) - 2 = 38.x - 3: a = 3, p(a) = 4(3)³ + 6(3)² - 8(3) - 2 = 136.x + 1: a = -1, p(a) = 4(-1)³ + 6(-1)² - 8(-1) - 2 = 8.x + 2: a = -2, p(a) = 4(-2)³ + 6(-2)² - 8(-2) - 2 = 6.x + 3: a = -3, p(a) = 4(-3)³ + 6(-3)² - 8(-3) - 2 = -32.
