Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cube
kvasek [131]

Answer:

C

Step-by-step explanation:

Tomas learned that

a^3+b^3=(a+b)(a^2-ab+b^2)

If a=2x,\ b=y, then

a^3+b^3\\ \\=(2x)^3+y^3\\ \\=((2x)+y)((2x)^2-(2x)y+y^2)\\ \\=(2x+y)(4x^2-2xy+y^2)

An industrial psychologist consulting with Lara music stores knows that the average number of complaints management receives eac
xeze [42]

Answer:

Step-by-step explanation:

H0 : μ ≥ 6

H1 : μ < 6

Test statistic :

n = 20

Sample Mean, x = 3

σ = 1.5

Test statistic = (x - μ) ÷ σ/sqrt(n)

Test statistic = (3 - 6) ÷ 1.5/sqrt(20)

Test statistic = - 3 / 0.3354101

Test statistic = −8.944271

Since, sample size is < 30 ;

Obtaining the Critical value using the from T;

Tcritical at 0.05, df = 19 = - 1.729

Tstatistic < Tcritical

−8.944271 < - 1.729

Hence, we reject the Null:

We can conclude that there is significant evidence that the number of complaints received by Lara music store is different from number of complaints received by music stores in general.

A triangle has sides with lengths of 14 yards 17 yards and 18 yard is it a right triangle yes or no
ella [17]

The given sides of the triangle are : 14 yards, 17 yards & 18 yards.

Condition of a right angle triangle :

1) The sum of square of Base and the perpendicular sides of traingle are always equal to the square of Hypotenuse.

Hypotenuse² = Perpendicular² + Base²

where, Hypotenuse, Base and perpendicular are express as :

2) The hypotenuse side of the right angle triangle is always the longest side.

In the given sides of triangle :

18 is the longest one, consider 18 as the Hypotenuse and remaing as the perpendicular and base

i.e.

Hypotenuse = 18, Base = 17 and perpendicular = 14

Substitute the value in the expression of the second condition :

Hypotenuse² = Perpendicular² + Base²

18² = 14² + 17²

324 = 196 + 289

324 = 485

LHS is not equal to RHS

Thus, expression doesnot hold

Hence the given sides of triangle is not a right angle triangle

Answer : The given sides of triangle is not a right angle triangle
