Answer:

I need about     41   liters of gas to fill my tank

Step-by-step explanation:

Full tank: 17 gallons

Amount of gas in tank now: 6 gallons

Amount needed to fill tank: 17 gallons - 6 gallons = 11 gallons

The amount needed to fill the tank is 11 gallons.

Now we convert 11 gallons to liters.

We use conversion fractions, first from gallons to quarts, then from quarts to liters.

11 gallons * (4 quarts)/(1 gallon) * (0.94 liter)/(1 quart) = 41.36 liters

The probability of reaching into the box and randomly drawing a chip number that is smaller than 201 is 190/359.

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

The favourable choices are 11,12............200

x = 14

Step-by-step explanation:

x + 10 = 2x - 4

x + 10 - 10 = 2x - 4 - 10

x = 2x - 14

x - 2x = 2x - 2x - 14

Based on the properties of rectangles, the angles and the side lengths are KN = 11 and NLK = 32

From the question, we have the following parameters that can be used in our computation:

JN = 2x + 7, LN = 6x - 1

NKJ = 58 degrees

The diagonals or a rectangle are equal

So, we have

2x + 7 = 6x - 1

Evaluate the like terms

4x = 8

Divide

x = 2

So, we have

KN = 2 * 2 + 7

KN = 11

Adjacent angles in this case add up to 90 degrees

This gives

NLK = 90 - 58

Evaluate

NLK = 32

Hence, the measure of the angle is 32 degrees

From the equation we see that the center of the circle is at (-2,3) and the radius is 9.

So using the distance formula we can see if the distance from the center to the point (8,4) is 9 units from the center of the circle...

d^2=(8--2)^2+(4-3)^2  and d^2=r^2=81 so

81=10^2+1^2

81=101  which is not true...

So the point (8,4) is √101≈10.05 units away from the center, which is greater than the radius of the circle.  

Thus the point lies outside or on the exterior of the circle...

Number of blue markers  = 9

Step-by-step explanation:

Given that there are 24 red markers.

Probability of randomly choosing a red marker is 1 in 3.

Probability of an event E is given as:

\(P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}\)

That means the ratio of red markers to total markers is 1:3.

Here number of favorable cases are 24 i.e. the number of red markers

and Total number of cases are equal to total number of markers.

Let T be the total number of markers.

As per definition of probability:

\(\dfrac{1}{3}=\dfrac{24}{T}\\\Rightarrow \bold{T = 72}\)

Also, given that the probability of choosing a blue marker is 1 in 8.

Let the number of blue markers be B.

As per definition of probability:

\(\dfrac{1}{8}=\dfrac{B}{72}\\\Rightarrow \bold{B = 9}\)

Hence, the answer is:

Number of blue markers  = 9

The missing parts of the proof includes;

1) ∠ABC = m∠CBD + m∠ABD = 90° (Angle addition postulate)

2) m∠CBD = m∠ABD (Definition of angle bisector)

3) m∠CBD + m∠ABD  = m∠CBD + m∠CBD (Substitution property of equality)

Step-by-step explanation:

The given details of the proof are;

∠ABC is a right angle = 90°

Line DB is a bisector of ∠ABC

Therefore;

1) ∠ABC = m∠CBD + m∠ABD = 90° by angle addition postulate

By the definition of angle bisector, we have;

The angles formed by line DB from ∠ABC are equal,

2) m∠CBD = m∠ABD by the definition of angle bisector

3) m∠CBD + m∠ABD = 90° = m∠CBD + m∠CBD = 2 × m∠CBD by substitution property of equality

2 × m∠CBD = 90°

∴ m∠CBD = 90°/2 = 45°

The Lagrange error bound is a method for estimating the error in approximating a function using a polynomial

Let's say you have a function f(x) and you want to approximate it using a polynomial of degree n, denoted by Pn(x). The Lagrange error bound states that the absolute error between f(x) and Pn(x) is bounded by:

|f(x) - Pn(x)| ≤ M/[(n+1)!] |x - c|^(n+1)

where M is a bound on the (n+1)th derivative of f(x) on an interval containing x and c is some constant value in that interval (typically the midpoint of the interval). Note that the bound depends on the choice of x and c.

In practice, the Lagrange error bound can be used to estimate the error in polynomial approximations. You can choose a value of x and a degree n for the polynomial, then use the bound to find an upper bound on the absolute error. If the error is too large, you may need to increase the degree of the polynomial or choose a different value of x.

The given question is complete, the complete question is:

What is Lagrange error bound ?

The minimum sample size needed to estimate u for the given values of c, o, and E is `39`.

Given that the level of confidence is `c = 0.98`, the margin of error is `E = 2`, and the standard deviation is `σ = 7.6`.The formula to find the minimum sample size is: `n = (Zc/2σ/E)²`.Here, `Zc/2` is the critical value of the standard normal distribution at `c = 0.98` level of confidence, which can be found using a standard normal table or calculator.Using a standard normal calculator, we have: `Zc/2 ≈ 2.33`.

Substituting the values in the formula, we get:n = `(2.33×7.6/2)²/(2)² ≈ 38.98`.Since the sample size should be a whole number, we round up to get the minimum sample size as `n = 39`.

Therefore, the minimum sample size needed to estimate u for the given values of c, o, and E is `39`.

Answer:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope (rate of change) and b is the y-intercept (where the line crosses the y-axis).

In this case, the number of times the insect beats its wings is the dependent variable (y) and the flying time in seconds is the independent variable (x). We know that the insect beats its wings 240 times per second, so the slope of the equation is 240.

To find the y-intercept, we need to know the number of times the insect beats its wings when it has flown for 0 seconds. Since the insect starts beating its wings immediately, the y-intercept is 0.

So the equation in slope-intercept form is:

y = 240x + 0

This equation represents the relationship between flying time in seconds (x) and the number of times the insect beats its wings (y).

Also, it is important to note that, the slope (240) is the rate of change of the number of times the insect beats its wings per second.

The value of the expression is 4.

The code :

int a[4] = {1, 2, 3, 4};

int *p = a;

what is *(p + 3)?

The variable a is an array of integers, and the variable p is a pointer to the first element of the array.

The expression *(p + 3) is the value of the element of the array that is 3 elements after the element that p points to.

Since p points to the first element of the array, the expression *(p + 3) is the value of the fourth element of the array, which is 4.

Therefore, the value of the expression is 4.

Here is a breakdown of the code:

int a[4] = {1, 2, 3, 4}: This line declares an array of integers called a and initializes it with the values 1, 2, 3, and 4.

int *p = a; This line declares a pointer to an integer called p and initializes it with the address of the first element of the array a.

what is *(p + 3)?: This line asks what the value of the expression *(p + 3) is.

The expression *(p + 3) is the value of the element of the array that is 3 elements after the element that p points to.

Since p points to the first element of the array, the expression *(p + 3) is the value of the fourth element of the array, which is 4.

The factored form is 2y(x - y) - 11x.

Factored form of a polynomial is when the polynomial is written as a product of its factors. Each factor is either a polynomial or a number. Factored form is useful for identifying the zeros of a polynomial and for solving polynomial equations.

To simplify the given expression, we need to combine like terms and factor if possible.

First, let's combine the like terms:

x^2 + 3xy - 4y^2 - 6x + 3y - x^2 - xy + 2y^2 - 5x - 3y

= 2xy - 2y^2 - 11x

Next, let's see if we can factor the expression:

2xy - 2y^2 - 11x

= 2y(x - y) - 11x

The required values of x and y are after solving the given equations are,

x= -22/9

y = -88/9

There are various ways to define an equation. A mathematical statement that demonstrates the equality of two mathematical expressions is the definition of an equation in algebra. For instance, the equation 3x + 5 = 14 comprises the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

We have the first equation,

 y = 4x

substitute this value in 2 nd equation for variable y

2x - 5y = 44

2x - 5 (4x) = 44

2x - 20x = 44

-18x = 44

x = -22/9

By now we know this much :

   y = 4x

   x = 22/9

In order to determine y, use the value of x.

   y = 4(-22/9) = -88/9

Hence,
