how do you explain the midpoint of cd is e (-1,0). one endpoint is c(5,2). what are the coordinates of the other endpoint?

1 answer:

5 0

Midpoint = (x1+x2 / 2 , y1+y2 / 2)

5 + x2 / 2 = -1
5 + x2 = -2
x2 = -7

2 + y2 / 2 = 0
2 + y2 = 0
y2 = -2

Other endpoint: (-7, -2)

What are the possible polynomial expression for dimensions of the cuboid whose volume is 12y2 + 8y -20

bogdanovich [222]

Answer:

The answer is below

Step-by-step explanation:

The volume of a cuboid is the product of its length, height and breadth. It is given by:

Volume = length × breadth × height

Since the volume is given by the expression 12y² + 8y - 20. That is:

Volume = 12y² + 8y - 20 = 4(3y² + 2y - 5) = 4(3y² + 5y - 3y -5) = 4[y(3y + 5) -1(3y + 5)]

Volume = 4(y-1)(3y+5)

Volume = 12y² + 8y - 20 = 2(6y² +4y - 10) = 2(6y² + 10y - 6y -10) = 2[y(6y + 10) -1(6y + 10)]

Volume = 2(y-1)(6y+10)

Therefore the dimensions of the cuboid are either 4, y-1 and 3y+5 or 2, y-1 and 6y+10

Answer:

A. Sam, Joe, Lynn, Kori

B. Kori, Lynn, Sam, Joe

Step-by-step explanation:

We need Kori and Lynn together and Kori and Sam at least a seat apart.

A. Sam, Joe, Lynn, Kori

B. Kori, Lynn, Sam, Joe

C. Lynn, Kori, Sam, Joe

D. Responses A and C

It seems both A. Sam, Joe, Lynn, Kori and B. Kori, Lynn, Sam, Joe both work. There is no choice for both of them so I'll just put both of them as my answer.

Consider the continuous random variable X, which has a uniform distribution over the interval from 20 to 28.

anastassius [24]

Answer:

a) The probability distribution is $f(x) = \frac{1}{8}$

b) 0.5 = 50% probability that X will take on a value between 21 and 25.

c) 0.25 = 25% probability that X will take on a value of at least 26.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{a - x}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

Uniform distribution over the interval from 20 to 28.

This means that $a = 20, b = 28$

a. What’s the probability density function?

The probability density function of the uniform distribution is:

$f(x) = \frac{1}{b - a}$

In this question:

$f(x) = \frac{1}{28 - 20} = \frac{1}{8}$

b. What’s the probability that X will take on a value between 21 and 25?

$P(21 \leq X \leq 25) = \frac{25 - 21}{28 - 20} = \frac{4}{8} = 0.5$

0.5 = 50% probability that X will take on a value between 21 and 25.

c. What’s the probability that X will take on a value of at least 26?

$P(X > 26) = \frac{28 - 26}{28 - 20} = \frac{2}{8} = 0.25$

0.25 = 25% probability that X will take on a value of at least 26.
