Answer:

The first one

sorry if I'm wrong

To add 2 1/2 + 4/5 using a number line, we can start by marking off the whole numbers along the number line. Then, we can divide each whole number into equal parts to represent the fractions. For example, if we divide each whole number into fifths, we can mark off 2 1/5, 2 2/5, 2 3/5, etc.

After the above, the next thing is that we can find the point on the number line that represents 2 1/2 by starting at 2 and moving 1/5 of the way to the right. Similarly, we can find the point that represents 4/5 by starting at 4 and moving 1/5 of the way to the right.

Finally, to add the two numbers, we can simply move from the point that represents 2 1/2 to the point that represents 4/5. The final point we reach will be the sum of 2 1/2 + 4/5. In this example, the final point will be 3 3/10.

Therefore, 2 1/2 + 4/5 will be 3 3/10.

The equation of the line passing through the points (0, 3) and (-5, 0) is y = -3/5 x + 3

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept.

Here,

To find the equation of the line passing through the points (0, 3) and (-5, 0), we can use the slope-intercept form and the slope formula:

m = (y2 - y1) / (x2 - x1) = (0 - 3) / (-5 - 0) = -3/5

where (x1, y1) = (0, 3) and (x2, y2) = (-5, 0) are the coordinates of the given points.

Now we can substitute the value of m and the coordinates of one of the points into the equation of the line to find the value of b:

y = mx + b

3 = (-3/5)*0 + b

b = 3

So the equation of the line passing through the points (0, 3) and (-5, 0) is:

y = -3/5 x + 3

We can also convert the equation to point-slope form as :

y - y1 = m(x - x1)

y - 3 = (-3/5)(x - 0)

y - 3 = -3/5 x

y = -3/5 x + 3

Hence, the equation of the line passing through the points (0, 3) and (-5, 0) is y = -3/5 x + 3

The value of -0.6675 for the correlation coefficient of X and Y indicates that there is a negative correlation between the two variables.

The correlation coefficient, denoted as p, is a measure of the linear relationship between two random variables X and Y. It is defined as the ratio of the covariance of X and Y to the product of their standard deviations:

p = cov(X,Y) / (stdDev(X) × stdDev(Y))

To compute the correlation coefficient, we need to first calculate the covariance and the standard deviations of X and Y.

Since the marginals pdfs of X and Y are the same, we know that the expected value (mean) of X is equal to the expected value of Y, which is denoted as Mu x = Mu y = A.

The expected value of XY is given as E(XY) = 2/5.

The covariance of X and Y is defined as E((X-Mu x )(Y-Mu y )), which simplifies to E(XY) - Mu x × Mu y

Substituting the given values, we have:

cov(X,Y) = E(XY) - Mu x × Mu y = 2/5 - A²

To calculate the standard deviation of X and Y, we need to calculate the variance first. The variance of X is defined as E(X²) - (Mu x )²,

which can be easily calculated by replacing x with y in fx(x) and applying the same formula.

The standard deviation is the square root of the variance, so we have:

stdDev(X) = √(variance(X)) = √(E(X²) - (Mu x )²)

stdDev(Y) = √(variance(Y)) = √(E(Y²) - (Mu y )²) = √(E(X²) - (Mu x )²)

Now we can substitute these values into the formula for p:

p = cov(X,Y) / (stdDev(X) × stdDev(Y)) = (2/5 - A²) / (√(E(X²) - (Mu x )²) × √(E(X²) - (Mu x )²)).

Doing moves to keep an equation balanced is a powerful part of solving equations, but thinking about what the structure of an equation tells us about the solutions is just as iimportant

Sometimes it’s possible to look at the structure of an equation and tell if it has infinitely many solutions or no solutions. For example, look at

2(12x + 18) + 6 = 18x + 6(x + 7)

Using the distributive property on the left and right sides, we get

24x + 36 + 6 = 18x + 6x + 42

From here, collecting like terms gives us

24x + 42 = 24x + 42

Since the left and right sides of the equation are the same, we know that this equation is true for any value of x without doing any more moves!

Similarly, we can sometimes use structure to tell if an equation has no solutions. For example, look at

6(6x + 5) = 12(3x + 2) + 12

If we think about each move as we go, we can stop when we realize there is no solution

1/6 · 6(6x + 5) = 1/6 · (12(3x + 2) + 12) Multiply each side by 1/6

6x + 5 = 2(3x + 2) + 2 Distribute 1/6 on the right side.

6x + 5 = 6x + 4 + 2 Distribute 2 on the right side.

The last move makes it clear that the constant terms on each side, 5 and 4 + 2, are not the same. Since adding 5 to an amount is always less than adding 4 + 2 to that same amount, we know there are no solutions.

their slopes are the same so they're parallel

The expression, 5 ÷ 3, in standard form, would be 1. 67 x 10⁰.

For the purposes of representing large or small numbers in mathematics, a standard form of a number is essentially mentioned. To represent such numbers in standard form, we employ exponents.

It would be easier to understand the correct definition of standard form if you used decimal numbers and adhered to specific restrictions. As is well known, fractions are expressed more simply as decimal numbers.

Basically, in standard form, we try to ensure that only one digits is to the left of the decimal point and then to the right are the rest of the digits in the number. The position of the number is then reflected as a power of 10.

First, solve 5 ÷ 3 :

= 5 / 3

= 1. 667

The result already has only one number to the left of the decimal so the power of 10 would be 0:

= 1. 667 x 10⁰

This is because every number to the power 0, is 1 and so 1.667 x 10⁰ would be the same as 1. 667 x 1 which is correct.

Answer:

the patient would receive 375 mL of fluid in 3 hours.

Step-by-step explanation:

To calculate the amount of fluid a patient would receive in 3 hours, we can use the formula:

Flow rate (mL/hr) = Total volume (mL) / Time (hr)

Flow rate = 1000 mL / 8 hr = 125 mL/hr

To find the amount of fluid a patient would receive in 3 hours, we can use the formula:

Volume = Flow rate x Time

Volume = 125 mL/hr x 3 hr = 375 mL

So the patient would receive 375 mL of fluid in 3 hours.

In the above equation, swap out BD = 7x-10, BC = 4x-29, and CD = 5x-9.

BD = 88

BC = 27

CD = 61.

Given that BD is equal to 7x, BC is equal to 4x, and CD is equal to 5x,

It is evident from the above figure that Points B, C, and D are parallel. On line segment BD, point C is located.

BD = BC + CD

In the above equation, swap out BD = 7x-10, BC = 4x-29, and CD = 5x-9.

7x - 10 = (4x - 29) + (5x - 9)

When we combine similar phrases, we obtain

7x - 10 = (4x + 5x) + (-29 - 9 )

7x - 10 = 9x - 38

38 plus 38 on either side.

7x - 10 + 38 = 9x

7x + 28 = 9x

Take 7x away from both sides.

28 = 9x - 7x

28 = 2x

By 2, divide both sides.

14 = x

Consequently, x has a value of 14.

BD  = x - 10 = 7(14) - 10 = 88

88 units are BD's worth.

BC = 4x - 29 = 4(14) - 29 = 27

[tex]7^{2} + 5^{2} = c^{2}[/tex]

We will simplify our exponents:

[tex]49 + 25 = c^{2}[/tex]

Then adding them together gives us:

[tex]74 = c^{2}[/tex]

Then, we square root both sides giving us:

[tex]\sqrt{74} = c[/tex]

Then, we cannot simplify past this, since 74's prime factorization doesn't allow it. So, [tex]c = \sqrt{74}[/tex].

Hope this helped!

A graph which could represent a cubic function include the following: C. Graph C.

In Mathematics, a function is a mathematical expression which can be used for defining and showing the relationship that exist between two or more variables in a data set.

In Mathematics, a cubic function is sometimes referred to as a cubic polynomial and it can be defined as a type of polynomial in which the degree of the highest term (coefficient or exponent) is equal to three (3).

In this context, we can reasonably infer and logically deduce that a graph that represents a cubic function is graph C because it models this polynomial y = x³.
