The value of m = 15 makes the equation a proportional relationship.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side

The given equation is y + m = 6x + 15.

If an equation has a proportional relationship, then the two variables will have a constant ratio.

General format of a proportional relationship is y = kx, where k is called the constant of proportionality.

We have to get the given equation in the form of y = kx.

It is possible only if m = 15.

y + 15 = 6x + 15

y = 6x + 15 - 15

y = 6x

Hence the value of m is 15, if the relationship is proportional.

Answer:

1/36, or approximately 0.028

Step-by-step explanation:

The probability of getting the same number on two six-sided dice is 1/6, or approximately 0.17.

This is because there are six possible outcomes for each dice, and only one of those outcomes results in the same number on both dice (for example, both dice showing a 6).

So, out of the 36 possible outcomes when rolling two dice, only one of them results in the same number on both dice. Therefore, the probability of this happening is 1/36, or approximately 0.028.

The maximum rate of change of f(x,y,z)=x+y/z at the point (5,-3,5) can be found using the directional derivative.

The directional derivative of f(x,y,z) in the direction (u,v,w) is given by:

Df(x,y,z) = u∂f/∂x + v∂f/∂y + w∂f/∂z

Since f(x,y,z)=x+y/z, the partial derivatives of f(x,y,z) are ∂f/∂x=1, ∂f/∂y=1/z and ∂f/∂z=-y/z^2. Substituting these values into the above directional derivative equation, we get:

Df(x,y,z) = u + v/z - wy/z^2

At the point (5,-3,5), we get Df(5,-3,5) = u + (-3/5) - (5w)(-3/25)

Simplifying this expression gives us Df(5,-3,5) = u + 0.6w

Therefore, the maximum rate of change of f(x,y,z) at the point (5,-3,5) occurs in the direction (u,0,w) and has a value of 0.6w.

Glass A contains about twice as much as glass B.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Left Glass, height 10 cm , diameter 5.5 cm

And,  Right glass, height 3 cm , diameter 7 cm.

Now, We know that;

⇒ Volume of cylinder = πr²h

Where, 'r' is radius of the cylinder.

For left glass;

Height (h) = 10 cm ,

Diameter = 5.5 cm

⇒ Radius = 5.5 / 2

               = 2.75 cm

Hence, Volume = π × 2.75² × 10

                         = 3.14 × 2.75² × 10

                         = 237.46 cm³

For right glass;

Height (h) = 3 cm ,

Diameter = 7 cm

⇒ Radius = 7 / 2

               = 3.5 cm

Hence, Volume = π × 3.5² × 3

                         = 3.14 × 3.5² × 3

Step-by-step explanation:

The minimum value is -5 at x = 1. Coordinate (1,-5)

The area under the curve over the given interval [-5, 3] can be approximated using 4 left endpoint rectangles.

The formula for this is A = ∑f(xi)∆x. Where A is the area, f(x) is the function, xi is the left rectangles. of the interval, and ∆x is the width of the interval. For this problem, the function is f(x) = (x^2/2) + x + 2 and the given interval is [-5, 3]. So, the left endpoints of the intervals are x1 = -5, x2 = -1, x3 = 3, and x4 = 7 and the width of each interval is ∆x = 4. Plugging these values into the formula, A = (f(-5)∆x) + (f(-1)∆x) + (f(3)∆x) + (f(7)∆x). Simplifying, A = (9*4) + (6*4) + (12*4) + (26*4). Thus, the area under the curve over the given interval is A = 360.

Answer: y =1x-5

Step-by-step explanation:

The question asks for the slope form y =mx+b, where m is the slope and b is the y-intercept. The y-intercept is the y value when x = 0, also known as when the line intercepts the verticle origin line. On your graph, this point is (0, -5). So, b = -5. Now, we need to pick two points to find the slope using the equation (y2-y1)/(x2-x1). Any two points on the line will work, so even if you do not pick the same points as me, you should still get the same answer.

point one: (0,-5)

point two: (4,-1)

m = (-1 - -5) / (4 - 0) = (-1+5)/(4) = 4/4 = 1

Answer: a. The value of the firm the instant before it pays out current profits as dividends can be calculated using the Gordon Growth Model, which is given by the formula:

Value = Dividends / (Cost of Equity - Growth Rate)

Where Dividends = Current Profits, Cost of Equity = Opportunity Cost of Funds, and Growth Rate = Constant Annual Growth Rate.

Substituting the given values into the formula, we get:

Value = 900,000 / (0.04 - 0.02) = 900,000 / 0.02 = 45,000,000

b. The instant after it pays out current profits as dividends, the firm's value will be reduced by the amount of the dividends paid out. So, the value of the firm after paying out the dividends will be:

Value = 45,000,000 - 900,000 = 44,100,000

As given in the question,

Given set of linearly independent vectors are:

S={(3,2),(−1,1),(4,0)}

Let us consider vectors u , v , and w represents the given set of linearly independent vectors which is given by :

u = ( 3, 2 )

v = ( -1 , 1 )

w = ( 4, 0 )

To get the nontrivial linear combination of vectors whose sum is equal to zero that is ( 0 ,0 ) is given by :

( 3, 2 ) - 2( -1 , 1 ) - (5 / 4)(4 ,0 ) = (0 , 0)

P(A) and P(B) are independent events.

Option (D) is correct.

What are events in probability?

In probability, an event is a set of outcomes of an experiment. For example, if you flip a coin, the possible outcomes are "heads" or "tails", and the event "getting heads" is the set of all outcomes where the coin lands on heads. Events can be mutually exclusive, meaning that they cannot happen at the same time, or they can be non-exclusive, meaning that they can happen at the same time.

The events A and B are independent. This means that the probability of event B happening (the second card selected is red) is not affected by whether or not event A has already happened (the first card selected is red).

In other words, the probability of selecting a red card on the second draw is still 1/2, regardless of whether a red card or a black card was selected on the first draw. This is because the cards are being drawn with replacement, meaning that the first card selected is returned to the stack before the second card is drawn, so the second draw is not affected by the first draw.

To calculate the probability of both events A and B happening, we can use the formula P(A and B) = P(A) x P(B|A) where P(B|A) is the conditional probability of event B given that event A has already happened. Since we know that the probability of event A is 1/2, and the probability of event B is also 1/2, we can calculate P(A and B) as: P(A and B) = (1/2) x (1/2) = 1/4

Therefore, P(A) and P(B) are independent events.

Option (D) is correct.
