a museum room, circular in shape, has 5 equally spaced sensors on its walls. there are no dead or overlapping spots along the perimeter of the room. each sensor has the same angle of detection. what is the detection angle of each sensor?

Answers

Answer 1

According to the given information the detection angle is 72.

How would you define an angle?

An angle is formed anytime two straight lines and rays meet at a single terminal. The intersection of two points at such an angle is known as the vertex. The word "angle" comes from the Latin word "angulus," which meaning "corner."

What is the math behind angles?

Degrees are a measure representing circularity or rotation and are used to express angles. You would turn 360° in order to face back in the exact direction after completing a full revolution. As a result, a quarter-circle, or straight angle, is 90°, and a half-circle is 180°. The sum of any two or maybe more angles on the a straight line is 180°.

n bridge, there are 4 players (a, b, c, d) and each player receives thirteen cards (from a standard shuffled deck of 52 cards). what is the probability that (a) exactly 1 of the 4 players has exactly one ace and one king?

Answers

The probability that exactly one of the 4 players has exactly one ace and one king is 4/221.

What is probability ?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means that an event is impossible and 1 means that an event is certain. Events with a probability of 0.5 or greater are considered likely to happen, while events with a probability of less than 0.5 are considered unlikely to happen.

There are 4 players and each player receives thirteen cards. Each player has 4 aces and 4 kings out of the 52 cards.

The probability that exactly one of the 4 players has exactly one ace and one king ,

There are 4 ways to choose the player who gets the ace and king.

The probability that the chosen player gets an ace is 4/52.

The probability that the chosen player gets a king after getting an ace is 3/51.

so the probability that exactly one of the 4 players has exactly one ace and one king is ,

4*(4/52)*(3/51) = 4/221

Therefore, the probability that exactly one of the 4 players has exactly one ace and one king is 4/221.

The melting point of ice is 0 degree celsius. during a chemistry experiment, jill observed ice melting within 2 degrees celsius of this measurement. find the range of temperature that jill observed. define a variable, write an inequality, and solve.

Answers

The typical definition of the melting point is the temperature at which a substance transforms from a solid to a liquid.

What do you mean by melting point?

melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached.

The melting point of a liquid is the temperature at which the liquid transforms from a solid to a liquid under atmospheric pressure. This is the location where the liquid and solid phases are equally present. The substance's melting point varies with pressure as well and is reported at standard pressure.

As the melting point is 0 °C.

So, it melts at 2 C. It can melt from 0 °C – 2 °C to 0 °C + 2 °C.

Please can someone help!​

Answers

Answer:

see explanation

Step-by-step explanation:

(a)

x - 9y = 10 ( add 9y to both sides )

x = 9y + 10 → (1)

3y² = 4x + 7 → (2)

substitute x = 9y + 10 into (2)

3y² = 4(9y + 10) + 7

3y² = 36y + 40 + 7

3y² = 36y + 47 ( subtract 36y + 47 from both sides )

3y² - 36y - 47 = 0 ← as required

(b)

solving using the method of completing the square

add 47 to both sides

3y² - 36y = 47 ← factor out 3 from each term in the left side

3(y² - 12y) = 47

to complete the square on the left

add/subtract ( half the coefficient of the y- term)² to y² - 12y

3(y² + 2(- 6)y + 36 - 36) = 47

3(y - 6)² - 3(36) = 47

3(y - 6)² - 108 = 47 ( add 108 to both sides )

3(y - 6)² = 155 ( divide both sides by 3 )

(y - 6)² = [tex]\frac{155}{3}[/tex] ( take square root of both sides )

y - 6 = ± [tex]\sqrt{\frac{155}{3} }[/tex] ≈ ± 7.2 ( to 1 decimal place )

add 6 to both sides

y = 6 ± 7.2

then

y = 6 - 7.2 = - 1.2

y = 6 + 7.2 = 13.2

substitute these values into ( 1) for corresponding values of x

x = - 1.2 : x = 9(- 1.2) + 10 = - 10.8 + 10 = - 0.8 ⇒ (- 1.2, - 0.8 )

x = 13.2 : x = 9(13.2) + 10 = 118.8 + 10 = 128.8 ⇒ (13.2, 128.8 )

Answer:

  (x, y) ≈ (-0.7, -1.2) or (128.7, 13.2)

Step-by-step explanation:

You want the solution to the simultaneous equations ...

x -9y = 103y² = 4x +7

a) Quadratic

Solving the first equation for x, we can substitute into the second equation to get a quadratic in y.

  x = 9y +10 . . . . . . . add 9y to the first equation

  3y² = 4(9y +10) +7 . . . . . substitute for x

  3y² = 36y +47 . . . . . . . eliminate parentheses

  3y² -36y -47 = 0 . . . . subtract the right-side expression

b) Solutions

The equation can be written in vertex form as ...

  3y² -36y = 47

  3(y² -12y +36) = 47 +3(36)

  3(y -6)² = 155

  y -6 = ±√(155/3)

  y = 6 ± (√465)/3 ≈ -1.19, 13.19

  x = 9y +10 ≈ -0.69, 128.69

The approximate solutions are ...

  (x, y) ≈ (-0.7, -1.2), (128.7, 13.2)

A quadrilateral is a parallelogram if and only if opposite angles are equal.

So, to make the quadrilateral a parallelogram, we can set the following equalities:

(4x + 13) deg = (5x - 12) deg

(4y + 7) deg = (3x - 8) deg

Solving the first equation,

4x + 13 = 5x - 12

x = -5

Solving the second equation,

4y + 7 = 3(-5) - 8

4y + 7 = -17

4y = -24

y = -6

So, the values of x and y that make the quadrilateral a parallelogram are x = -5 and y = -6

if we spin the two spinners at the same time, what is the probability that both spinners will yield odd numbers?]

Answers

There is a 1/2 probability that both spinners will produce an odd number.

What is probability?

The probability is equal to the variety of possible outcomes.

The total number of outcomes that could occur.

For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). P(heads) = 12 is what we write.

So, assume that:

Both the spinners have 1 positive number and 1 odd number.

Probability formula:

P(E) = Favourable events/Total events

Now, calculate as follows:

P(E) = Favourable events/Total events

P(E) = 2/4

P(E) = 1/2

Therefore, there is a 1/2 probability that both spinners will produce an odd number.

Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within.Your results will deviate by how many percentage points from the actual population value, according to your margin of error. It is described as a very small percentage that is allowed for error in calculations.

Given:

π ± [tex]z\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]

Here z is the z score which has a pvalue of

[tex]1 -\alpha /2[/tex]

The margin of error is given as:

[tex]M = z\sqrt{\frac{\pi (1-\pi )}{n} }[/tex]

79 percent of adults age 18 years and older in the United States use the Internet as found by a survey.

So, [tex]\pi =0.79[/tex]

98% confidence level

Now [tex]\pi =0.02[/tex], z is the value of Z that has a pvalue of  [tex]1-\frac{0.02}{2} =0.99[/tex].

So, Z =2.33.

The sample size (n) needed can be estimated using:

a movie theatre models the revenue from ticket sales in one day as a function of the ticket price, p. here are two expressions defining the same revenue function. p ( 120p - 4p ) and 120p - 4p 2 according to this model, how high would the ticket price have to be for the theater to make $0 in revenue? explain your reasoning. what equation can you write to find out what ticket price(s) would allow the theater to make $600 in revenue?

Answers

The ticket prices that would allow the theater to make $600 in revenue are $120 and $13.4.

In order for the theater to make $0 in revenue, the ticket price would have to be $4. This can be determined by setting the revenue functions equal to 0 and solving for p.

For p (120p - 4p) = 0

120p - 4p = 0

4p = 120

p = $30

For 120p - 4p2 = 0

120p - 4p2 = 0

4p2 = 120p

p2 = 30p

p = $4

To find the ticket prices that would allow the theater to make $600 in revenue, we can set the revenue functions equal to 600 and solve for p.

For p (120p - 4p) = 600

120p - 4p = 600

4p = 120 + 600

p = $120

For 120p - 4p2 = 600

120p - 4p2 = 600

4p2 = 120 + 600

Answers

12 tons of gravel has been used for the driveway.

Weight of first load = 7 tons

Weight of second load = 8000 pounds

There are 2000 pounds (lb) in one US customary ton (t). Both tons and pounds are measurements of mass/weight in the US customary and imperial systems of measurement. However, the definitions of the ton vary in both systems. For example, there are 2240 pounds in an imperial ton, and 2204.6226 pounds in a metric ton.

The US ton is mostly used in the United States and Canada. The imperial ton was mostly used in the UK, and still is to a degree, but since the UK began the process of metrication, the metric ton is also used in the UK.

Convert pounds to tons:

1 pound = 0.0005 ton

8000 pounds = 4 ton

Then,

Weight of second load = 4 ton

Total weight of the gravel, in tons = Weight of first load + Weight of second load

= 8 tons + 4 tons

= 12 tons

Thus, 12 tons of gravel has been used for the driveway.

If the same experimental design was used but with an endotherm (an organism that generates heat internally) instead of an ectotherm (an organism that relies on external sources of heat), I would expect to see a difference in the organism's ability to regulate its body temperature. Endotherms have a higher metabolic rate and are able to generate heat internally, whereas ectotherms rely on external sources of heat to regulate their body temperature. This means that endotherms would be less affected by changes in external temperature and would be able to maintain a more stable body temperature. Additionally, endotherms would likely have a higher tolerance for cold temperatures. I came to this conclusion because endotherms have internal heat regulation mechanisms that allow them to maintain a stable body temperature, whereas ectotherms do not.

[tex]\begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\qquad \implies \qquad \begin{array}{llll} y=-\cfrac{5}{4}(~~x-(-1)~~) \\\\ {\Large \begin{array}{llll} y=-\cfrac{5}{4}(x+1) \end{array}} \end{array}[/tex]

The graph of y - 3 = 2.5( x - 1) is shown. The graph can be used to model the amount of water. Y, being poured into an 8 ounce glass over x seconds. What is the range given the context?

Answers

The range of the function, considering the context of this problem, is given as follows:

[0.5, 8].

How to obtain the range of a function?

The range of a function is the set that contains all the possible output values for the function.

The output variable in this context is given as follows:

Amount of water into the 8 ounce glass.

The y-intercept of the graph is obtained as follows:

y - 3 = 2.5(0 - 1)

y = -2.5 + 3

y = 0.5.

Hence the lower bound of the range is of 0.5.

The maximum capacity of the glass of water is of 8 ounces, hence the upper bound of the range is of 8.

The range is composed by a closed interval, as the amounts of 0.5 ounces and 8 ounces can be assumed by the function.

a quantity with an initial value of 510 grows exponentially at a rate such that the quantity doubles every 8 decades. what is the value of the quantity after 7 years, to the nearest hundredth?

Answers

After five decades, the amount is worth to the nearest hundredth is 607.54

Any decimal number is rounded to the nearest hundredth by the term "to the nearest hundredth." A hundredth is 1/100 or 0.01 in decimal form. For instance, 2.17 is the result of rounding 2.167 to the nearest tenth.

Look at the next place value to the right in order to round a number to the closest hundredth (the thousandths this time). The same applies: Simply eliminate all the digits to the right if the number is 4 or fewer. Add 1 to the digit in the hundredths place if the number is five or above, and then eliminate all the digits to the right.

The equation below can be used to describe this amount at intervals of 2t decades. where r is the rate of increase and Q(0) is the initial quantity. A 510-valued quantity increases exponentially at a rate of 7% every 20 years. After five decades, the amount is worth 607.54

Q(t)=Q(0)[tex]e^{xt}[/tex]

Q(2.5)= 510e^(0.07*2.5)

= 607.54

A line passes through the point (-6, -7) and has a slope of 2. Write an equation in point-slope form for this line.​

Answers

Answer: (y + 7) = 2(x + 6)

Step-by-step explanation:

       A point-slope form equation is given as (y - y1) = m(x - x1) where (x1, y1) is a given coordinate point, m is the slope, and x and y are variables. We will substitute the given information into this base equation.

(y - y1) = m(x - x1)

(y - - 7) = 2(x - - 6)

(y + 7) = 2(x + 6)

The measure of the angles of a triangle are 50°, 60°, 70°. The triangle is acute-angle triangle.

What is an acute angle?

An acute angle is one that is less than 90 degrees in length. This is a smaller angle than the right angle (which is equal to 90 degrees).

Given that the measure of the angles of a triangle are x, x+10, and x+20.

The sum of the interior angles of a triangle is 180°.

According to the question,

x+x+10+x+20 = 180°

3x + 30 = 180°

3x = 150°

Divide both sides by 3:

x = 50°.

Putting x = 50° in x, x+10, and x+20.

x =50° , x+10 = 60°, and x+20 =70°.

All angles of the triangle is 90°. Thus the triangle is an acute angle triangle.
