Un binomio cuadrado perfecto es un trinomio que cuando factorizada le da el cuadrado de un binomio. Por ejemplo, el trinomio x ^ 2 + 2xy + y ^ 2 es un binomio cuadrado perfecto, ya que son los factores a (x + y) ^ 2.

Ok so first you have to solve what is inside parentheses , so 2 is on the outside and (7 +x) is on the inside so we are going to distribute which means 2 times 7 is 14 +2x.

Point XXX is located at (3, 2)(3,2)left parenthesis, 3, comma, 2, right parenthesis. Point YYY is located at (3, -8)(3,−8)left p

NeX [460]

Answer:

10

Step-by-step explanation:

Given that:

Point X = (3, 2)

Point Y = (3, - 8)

Distance of point X to Y:

Distance = √(x2 - x1)^2 + (y2 - y1)^2

X1 = 3 ; y1 = 2 ; x2 = 3 ; y2 = - 8

Distance = √(3 - 3)^2 + (-8 - 2)

Distance = √(0)^2 + (-10)^2

Distance = √0 + 100

Distance = √100

Distance = 10

Perform the indicated computation. Write the answer in scientific notation. 12x10^4\3x10^−2

Paul [167]

Let us consider the given expression:

$\frac{12 \times 10^{4}}{3 \times 10^{-2}}$ in the scientific notation.

= $\frac{12 \times 10^{4} \times 10^{2}}{3 }$

[Using the law of exponents, which states

$a^{m} \times a^{n} = a^{m+n}$ ]

= $\frac{12 \times 10^{6}}{3}$

On dividing, we get

= $4 \times 10^{6}$

Hence, it is the required scientific notation of the given expression.

There are currently 18 pit bulls at the pound. Of the 18 pit bulls, four have attacked another dog in the last year. Joe, a memb

laila [671]

Answer: 0.7748

Step-by-step explanation:

Given : Number of bit bulls at the pound = 18

Number of pit bulls have attacked another dog in the last year =4

The proportion of pit bulls have attacked another dog in the last year: $p=\dfrac{4}{18}\approx0.22$

Number of the pit bulls selected = 6

The probability of that none of the pit bulls in Joe's group attacked another dog last year : $P(0)=(1-0.22)^6=0.225199600704\approx0.2252$

By using binomial , the probability that at least one of the pit bulls in Joe's group attacked another dog last year is given by :-

$P(x\geq 1)=1-P(x$

Hence, the required probability = 0.7748
