well it would make sense to say that the longest fish is 12in longer than the shorter fish because if you take 21in (the longest fish) and subtract 9 (the shortest fish) you would get 12.

Hope that helped pls give brainlist

The cost of holding a children's birthday party at a rollerskating rink is a function of n, the number of people in the party. T

Bas_tet [7]

Answer: It would cost $150 for a party of 9 people and it would cost $260 for 20 people

Step-by-step explanation:

The number 9 falls in between 0<n<_ 12 so the cost is 150

The number 20 falls in between 12<n<_ 20 so the cost is 260

Softa [21]

Answer:

PN= $17,800

Step-by-step explanation:

<u>La formula general para calcular el activo de una empresa es la siguiente:</u>

<u></u>

A= PN + P

El activo es igual al patrimonio neto y el pasivo.

Debemos intercambiar los términos:

PN= A - P

Activo:

Caja= 10,000

Bancos= 13,500

Equipos de computación= 2,400

Documentos por cobrar= 5,100

Pasivo:

Cuentas por pagar= 8,000

Documentos por pagar= 4,000

Intereses por pagar= 1,200

PN= 31,000 - 13,200

PN= $17,800

It is commonly assumed that babies are equally likely to come as either a boy or a girl. This is not true. Actually, about 51.3%

Brums [2.3K]

Answer: 0.263169

Step-by-step explanation:

Since for every child there is two outcomes (either a boy or a girl), so it is a binomial distribution.

Let x = Number of boys

Given: probability that a child is a boy: p= 0.513

Binomial distribution formula : $P(X=x)=^nC_xp^x(1-p)^{n-x}$

Now, the probability that both children are boys= $P(X=2)=^2C_2(0.513)^2(1-0.513)^0$

$=(1)(0.513)^2(1)\\\\=0.263169$

The chance both children are boys = 0.263169

Given u = −8i − 3j and v = −12i − 7j, what is projvu?

8090 [49]

Answer:

(b) -7.275i -4.244j

Step-by-step explanation:

The projection of vector u onto vector v is the product of the unit vector v, the magnitude of vector u, and the cosine of the angle between them.

The dot product gives the product of the magnitudes of the two vectors and the cosine of the angle between them. To find the projection, we must divide the dot product by the magnitude of v and multiply by the unit vector in the direction of v.

$proj(u,v)=(\vec{u}\cdot\vec{v})\cdot\dfrac{\vec{v}}{|\vec{v}|^2}=\dfrac{((-8)(-12)+(-3)(-7))(-12\vec{i}-7\vec{j})}{(-12)^2+(-7)^2}\\\\=\dfrac{-(96+21)(12\vec{i}+7\vec{j})}{144+49}=-\dfrac{117}{193}(12\vec{i}+7\vec{j})\approx\boxed{-7.275\vec{i}-4.244\vec{j}}$
