Answer:196.65

Step-by-step explanation:

To find:

Round 6475.13 to the nearest ten.

Solution:

The unit digit of the number is 5 and the tens digit is 7.

When rounding up the tens digit, it will become 8 and the unit digit will be zero.

So, the number is 6480.

The expected value of the random variable E(X) of the the data will be equal to 4.0.

The expected value of a random variable X is given by the formula:

E(X) = ∑x * P(X = x)

where ∑ denotes the sum over all possible values of x.

In this case, the possible values of x are 2, 3, 4, 5, and 6, and the corresponding probabilities are 0.2, 0.1, 0.2, 0.1, and 0.4, respectively. Plugging these values into the formula, we get:

E(X) = (2 * 0.2) + (3 * 0.1) + (4 * 0.2) + (5 * 0.1) + (6 * 0.4)

= 0.4 + 0.3 + 0.8 + 0.5 + 2.4

= 4.0

Rounding to one decimal place, the expected value of X is 4.0.

The percentage change in GDP is 2.04%

Percentage Change is the difference coming after subtracting the old value from the new value and then divide by the old value and the final answer will be multiplied by 100 to show it as a percentage. Generally, to convert a fraction into a percent, we multiply it by 100.

The formula of percentage change is given as

Percentage change =[ (New increase - old value) / old value] * 100

Percentage change = [(14.72 - 14.42) / 14.72] * 100

Percentage change = 2.04%

Step-by-step explanation:

The  functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is  A = 500(1.1)^4

In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.

given:

P= $500

First, convert R as a percent to r as a decimal

r = R/100

r = 10/100

r = 0.1 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 500.00\((1 + 0.1/1)(1)^4\)

A = 500.00\((1.1)^4\)

A = $732.05

The support vector of the input dsolve('Dy = -3*y') is "dsolve(diff(y,t) == -3*y)".

A symbol is a mathematical object that represents a mathematical entity, such as a number, a variable, or a function. In mathematical software, symbols are used to represent variables, which can be used in mathematical expressions to perform computations.

In the past, character vectors or strings were used to represent symbols in certain mathematical software programs.

In the future release of this software, support for character vectors or strings will be removed. Instead, the program will require users to use the "syms" function to declare variables as symbols.

As an example of how this might be used in practice, consider the differential equation

=> "dy/dt = -3y".

In the past, this equation might have been entered into a mathematical software program using a character vector or string to represent the variable "y".

However, in the future release of this software, the user will need to use the "syms" function to declare "y" as a symbol. The equation would then be entered using the "diff" function, like this:

The increase in height (rise) of the balloon is \(35.53 feet\)

What is Pythagorean Theorem?

Pythagoras' theorem states that "the square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides."

The angle of elevation is generated by the intersection of the horizontal line and the line of sight. If the line of sight is directed upward from the horizontal line, the resulting angle is an angle of elevation.

According to the given information:

Given that,

Initial angle of elevation = \(19.3^{0}\).

Final angle of elevation = \(32.3^{0}\).

Distance = \(126 feet\).

How to calculate the height (rise).

In order to determine the increase in height (rise) of the balloon, we would apply Pythagorean Theorem. Mathematically, this is given by this formula:

tan∅ = \(\frac{height}{adj}\)

height = adjacent \(*\) tan∅

At an initial angle of elevation:

height \(=126* tan 19.3^{0} \\= 126 * 0.3501\\= 44.11 feet\)

At a final angle of elevation:

height \(=126* tan 32.3^{0} \\= 126* 0.6321\\= 79.64 feet\)

For the change in height:

Δh \(= 79.64-44.11\\=35.53 feet\)

Answer:

The difference between the numbers does not follow a common pattern; hence, the sequence is not arithmetic.

Step-by-step explanation:

Let's take the 1st two digits, 5 and 2

The difference between the numbers, 5-2 = 3

Following this pattern,

2-(-3) = 5

-3-(-10) = 7 and,

-10-(-19) = 9.

Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty.

Due to this:

p = 0.5

If Given f(x) = 1/2 (3 - x) ^ 2 , the value of f(15) is 72.

What is function?

In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range. In simpler terms, a function is a set of rules that takes an input value and produces a corresponding output value.

The given function is:

f(x) = 1/2 (3 - x)²

To find the value of f(15), we need to substitute 15 for x in the function:

f(15) = 1/2 (3 - 15)²

Here, we subtract 15 from 3 to get -12 in the parentheses, and then we square it to get 144. We can simplify the expression further by multiplying 144 by 1/2, which gives us 72:

f(15) = 1/2 (144)

f(15) = 72

The distance between Terrence’s house from the theater will be 2.4 miles.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Distance is defined as the length between the two points.

Let us suppose the following parameters to get the distance.

D = distance of Terrence’s house from the theater

v₁ = speed at which Terrence walks from home to the theater = 2 mi/h

t₁ = time taken by Terrence to walk from home to the theater = D/v₁ = D/2

v₂ = speed at which Terrence returns back to home = 40 mi/h

t₂ = time taken by Terrence to return back to home = D/v₂ = D/40

t' = time spent in watching the movie = 2 h 15 min = 2.25 h

t = total time = 3.5 h

The distance will be calculated as given below:-

t = t₁ + t₂ + t'

Answer:

The value is  \(P( 390 < X < 590) = 68.3 \%\)    

Step-by-step explanation:

From the question we are told that

   The mean is  \(\mu = 490\)

    The standard deviation is  \(\sigma = 100\)

Generally the proportion of seniors scored between 390 and 590 on this SAT test is mathematically represented as

     \(P( 390 < X < 590) = P( \frac{390 - 490 }{100} < \frac{\= x - \mu }{\sigma} < \frac{590 - 490 }{ 100} )\)

\(\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )\)

    \(P( 390 < X < 590) = P( -1 < Z < 1 )\)

=>  \(P( 390 < X < 590) = P(Z< 1 ) - P(Z < - 1 )\)

From the z table  the area under the normal curve to the left corresponding to  1 and  -1  is  

\(P(Z< 1 ) = 0.84134\)

and

\(P(Z< - 1 ) = 0.15866\)  

   \(P( 390 < X < 590) =0.84134 - 0.15866\)

=> \(P( 390 < X < 590) = 0.6827\)

Generally the percentage of seniors scored between 390 and 590 on this SAT test is mathematically represented as

=> \(P( 390 < X < 590) = 0.6827 *100\)    

=> \(P( 390 < X < 590) = 68.3 \%\)

Trapezoid have 4 length side lines

Now find proportions

Find height of trapezoid

Divide trapezoid in 1 rectangle and 2 triangles

Then , the 2 triangles have a base of (23-15)/2 = 4

Then height is 4 x WZ x sin 56

Angle Z = (180-56-90) + 90 = 124 degrees

Angle X = 360-124- 56 - 121= 59 degrees

Now look at line 23

Then WZ• cos56 + 15 + XY• cos 59 = 23

Now if both angles Z and Y were similar ,then

TR would be (WX + ZY )/2, because T divides half WZ

BUT theyre not similar, theres a little difference . Then find this difference

Use formula cos (a+b) = cosa• cosb- sina•sinb

then

cos 59 = cos56• cos3 - sin56•sin3

aproximate cos3= 1 , sin3=0

then WZ• cos56 + XY•cos 56 + 15 = 23

(WZ + XY)•(cos56) = 23-15= 8:

(WZ + XY) = 8/(cos56) = 14.285

(WZ + XY)/2 =7.1428

then TZ = 7.1428/2 =3.5714

Finally TR = 15 + 2•TZ cos 56 = 18.994

Lucky Chances” lottery a box has 100 balls. 60 balls are marked “Good.” 40 balls are marked, “Bad.” To play this lottery, you draw a ball at random and look

Over the course of 500 plays, you can expect to draw a "Good" ball 300 times.

Over the course of 500 plays, you can expect to draw a "Bad" ball 200 times.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

The probability of drawing a "Good" ball is 60/100 or 0.6.

The probability of drawing a "Bad" ball is 40/100 or 0.4.

We can use these probabilities to determine what will happen over the course of 500 plays:

On average, you can expect to draw a "Good" ball 0.6 times for every play. So over the course of 500 plays, you can expect to draw a "Good" ball 0.6 x 500 = 300 times.

On average, you can expect to draw a "Bad" ball 0.4 times for every play. So over the course of 500 plays, you can expect to draw a "Bad" ball 0.4 x 500 = 200 times.

Note that these are expected values based on the probabilities, and there is no guarantee that you will actually draw exactly 300 "Good" balls and 200 "Bad" balls.

However, over a large number of plays, the actual results should approach these expected values.

Thus,

Over the course of 500 plays, you can expect to draw a "Good" ball 0.6 x 500 = 300 times.

Over the course of 500 plays, you can expect to draw a "Bad" ball 0.4 x 500 = 200 times.
