Graph quadrilateral ABCD and find the most precise name (square, rectangle,

Pavlova-9 [17]

Answer:

Kite

Step-by-step explanation:

To graph quadrilateral with points:

A(-1,-2)

B(5,1)

C(-3,1)

D(-1,4)

Thus, we graph the the given points and join the corners. The quadrilateral formed has the following features:

Measure of segment AB= Measure of segment BD = 6.708 units

Measure of segment AC= Measure of segment CD = 3.605 units

Thus, adjacent pair of sides of the quadrilateral are congruent.

Major diagonal BC cuts the minor diagonal AD at point E such that:

Measure of segment AE= Measure of segment ED = 3 units

m∠AEB = m∠DEB = 90°

Thus, major diagonal is a perpendicular bisector of the minor diagonal.

The above stated features fulfills the criterion of a kite.

Hence, the given quadrilateral ABCD is a kite.

Factor the GCF:

IceJOKER [234]

The greatest common factor (GCF) is the product of the greatest common factors of the numerical coefficients and the variables involving x and y.

-12(x^4)y - 9x³y² + 3x²y³

-3x²y(4x² + 3xy - y²)

<span>Thus, the answer is letter A. </span>

3.8.10) Inclusions are defects in poured metal caused by contamitants. The number of (large) inclusions in cast iron follows a P

Afina-wow [57]

Answer:

a) P(X>=1) = 0,7293 or P(X>=1) = 72,93 %

b) P(X>=3) = 0,5686 or P(X>=3) = 56,86 %

c) y = 0,8494 mm³

d) λ = 1,69897 inc per mm³

Step-by-step explanation:

a) P(X>=1) = 1 - P(X=0)

P(X = 0) = λ⁰ * e∧⁻λ / 0! where λ = 2 in/mm³

P(X = 0) = e∧-2 ⇒ P(X = 0) = 0,2706

Then

P(X>=1) = 1 - 0,2706

P(X>=1) = 0,7293 or P(X>=1) = 72,93 %

b) 3 inc. in 4 mm³ = 2*4/3 λ = 2,67 inc. per mm³

P(X>=3) = 1 - P(X=1 ) - P(X=2)

P(X=1) = λ¹ * e∧-λ / 1! ⇒ P(X=1) = 2,67 *e∧- 2,67/1

P(X=1) = 0,1846

P(X=2) = λ² * e∧-λ / 2! ⇒ P(X=2) = (2,67)² * e ∧ - 2,67/2

P(X=2) = 7,1289* 0,06925/2 ⇒ P(X=2) = 0,2468

Then

P(X>=3) = 1 - 0,1846 - 0,2468

P(X>=3) = 0,5686 or P(X>=3) = 56,86 %

c) P(X>=1) = 0,98

and λ = 2*y where y is the quantity of material

P(X=0) = 1 - P(X>=1)

P(X=0) = 1 - 0,98 P(X=0) = 0,02

0,02 = (2*y)⁰ * e ∧ -2*y /0!

0,02 = 1 * e ∧ -2*y

Taking log on both sides of the equation

log (0,02) = -2*y - 1,69897 = - 2*y

y = 0,8494 mm³

d) P(X >=1 ) = 1 - P( X = 0)

0,98 = 1 - P( X = 0)

P( X = 0) = 0,02

0,02 = λ⁰ * e ∧ - λ / 0!

0,02 = e ∧ -λ

Taking log on both sides of the equation we get:

log ( 0,02 ) = - λ

- 1,69897 = - λ

λ = 1,69897 inc. per mm³
