ten points are placed on a circle. what is the greatest number of different lines that can be drawn so that each line passes through two of these points(A) 12 (B) 15 (C) 25 (D) 30(E) 36

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

hope this helps!

u = 2v  + (5/4)w .

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)

⇒ u -2v - ( 5 / 4 )w = 0

⇒ u = 2v + ( 5 / 4 )w

The best way for the materials engineer to carry out the randomization for this study is by using a table of random digits to divide the 40 roadways into 20 pairs and then, for each pair, flipping a coin to decide which pavement to use on which member of the pair.

This can be represented by the formula P(A|B) = P(A) * P(B|A), where P(A|B) is the probability of pavement type A being used on a given roadway, P(A) is the probability of pavement type A being used on any given roadway, and P(B|A) is the probability of a given roadway being used for pavement type A.

The probability of pavement type A being chosen for any given roadway is 1/2 (since there are two pavement types). The probability of a given roadway being used for pavement type A is also 1/2 (since there are two members of each pair). This means that the probability of pavement type A being chosen for a given roadway is equal to P(A|B) = 1/2 * 1/2 = 1/4.

By randomly assigning pavement types to each pair of roadways, the materials engineer is ensuring that her experiment is as fair and unbiased as possible. This will allow her to accurately compare the durability of the two different types of paving material.

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.

The probability of randomly selecting two women from 884 subjects is 1.

The probability of randomly selecting two women from 884 subjects can be calculated using the following formula: P(A and B) = P(A) x P(B). In this case, A is the event of randomly selecting a woman from 884 subjects and B is the event of randomly selecting a second woman from the remaining 883 subjects.

Therefore, P(A) = 884/884 = 1 and P(B) = 883/883 = 1. Thus, P(A and B) = 1 x 1 = 1. Then, the probability of randomly selecting two women from 884 subjects is 1. To round to four decimal places, the probability is 0.0000.

Answer:

To solve for g in the equation m + n^2 = g5M, we first need to isolate g on one side of the equation. We can do this by subtracting m and n^2 from both sides:

m + n^2 = g5M

m + n^2 - m - n^2 = g5M - m - n^2

0 = g5M - m - n^2

Now we can divide both sides by 5M:

0 = (g5M - m - n^2) / 5M

And we get the equation for g:

g = (m + n^2) / 5M

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.

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

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).

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
