What is the length of the line segment in the x-y plane with end points at (-2,-2) and (2,3)?Can anyone explain me how to make this one step by step?

Answers

Answer 1

Answer: You've got a formula. If the two endpoints are $A(x_A,y_A)$ and $A(x_B,y_B)$ , then the length is $√((x_B-x_A)^2+(y_B-y_A)^2)$ . The result is $√(16+25)=√(41)$ .

Consider a game in which players roll a number cube to determine the number of points earned. If a player rolls a prime number, that many points will be added to the player’s total. Any other roll will be deducted from the player’s total. What is the expected value of the points earned on a single roll in this game?

Answers

The expected value of the points earned on a single roll in the game would take into account the probability of the numbers of the cube and whether or not they're prime. If the cube is a dice with numbers 1 to 6, then the expected value of the points would be:
P = 1(1/6) + 2(1/6) + 3(1/6) - 4(1/6) + 5(1/6) - 6(1/6)
P = 1/6 or 0.1667

The product of two numbers is 450. the first number is half the second number. which equation can be used to find x, the greater number? = 450 225x2 = 0 x2 = 450 450x2 = 0

Answers

Answer:

let the two number be x and y.

Given: the product of two numbers is 450.

then: $x* y =450$ ......[1]

Also from the given condition that; the first number is half the second number. Also, x>y.

i.e, $y=(1)/(2)x$

Substitute this in equation [1];

$x * (1)/(2)x =450$

$(1)/(2)x^2 = 450$ [∴ $x^a * x^b =x^(a+b)$ ]

Multiply both sides by 2; we get

$x^2 =450 * 2$

$x^2=900$

$x=√(900) =30$

Now, substitute this x value in [1], to solve for y;

$30 * y=450$

Divide by 30 from both the sides, we get;

$y = (450)/(30)=15$

Therefore, the equation $(1)/(2)x^2 = 450$ which can be used to find the value of x.

The greater number is x = 30.

The equation is used to find x is;

$\rm x^2=900$

The value of the greater number x is 30.

Given

The product of the two numbers is 450.

The first number is half the second number.

Let the first number be x and the second number be y.

The product of the two numbers is 450.

$\rm x* y = 450$

The first number is half the second number.

$\rm x = (1)/(2) y$

Substitute the value of x in equation 1 from equation 2

$\rm x * y = 450\n\nx * (1)/(2)x = 450\n\nx^2 = 450 * 2\n\nx^2=900\n\nx=30$

Substitute the value of x in equation 1

$\rm x* y=450\n\n30 * y = 450\n\ny = (450)/(30)\n\ny = 15$

Hence, the value of the greater number x is 30.
