Answer:

a/2 + b unidades

Step-by-step explanation:

Mi primera lengua es ingles (tienes paciencia por favor). Se da que la parte inferior es a/2 unidades. La parte anaranjada tiene un lado que es b/2, entonces todos los lados son b/2 tambien. Entonces el lado del derecho es b/2. La izquierda es b/2 tambien ( se da eso). Entonces el perimetro del triangulo amarillo es a/2 + b/2 + b/2 = a/2 + b unidades.

Suppose xy=−2 and dy/dt=−4. Find dx/dt when x=−1.

Nikitich [7]

Answer:

-2

Step-by-step explanation:

Dividing the given equation by x, we find y to be ...

y = -2/x

Then ...

dy/dx = 2/x^2

and ...

dy/dt = (2/x^2)dx/dt

dx/dt = (x^2/2)dy/dt

When dy/dt = -4 and x=-1, this is ...

dx/dt = (-1)^2/2(-4) = (1/2)(-4)

dx/dt = -2

156 people said they spent the night in Wal-Mart the night before Black Friday to get the good deals! This number represented 39

Musya8 [376]

Answer: 400 Shoppers

Step-by-step explanation:

Given

156 people spent the night in Wal-mart

These 156 people represent 39% of total shoppers at Wal-mart

Suppose x is the total no of shoppers at Wal-mart

So, we can write

$\Rightarrow 39\%\ \text{of}\ x=156\\\Rightarrow 0.39\times x=156\\\\\Rightarrow x=\dfrac{156}{0.39}=400\ \text{People}$

If you wanted to make a game where you pay $5 if you can't guess a random dogs weight within 16lbs what payout should you offer

ella [17]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

The population std. dev of the dog weight=8

$\sigma=8\\\\P(\text{guess with in 16 lbs}) = P(|X-\mu|\leq 16)\\\\=P(-2 \leq Z \leq 2) = 0.9544\\\\$

Calculating the payout w s.t:

$E[netpay]=0=(-5) \times 0.9544+w\times (1-0.9544)\\\\ w =(5 \times \frac{0.9544}{1-0.9544}) =\$ 104.65$

therefore, we assume that the weight of the dog is a normal distribution with std. deviation that is 8.

In the floor tile pattern, the figure is a square and the two triangles are congruent.

Licemer1 [7]

Answer:

7.1

Step-by-step explanation:

Since it is a square you can use the Pythagorean theorem (a²+b²=c²) by filling in what you know. a²=5 and b²=5 so you have 5²+5²=c². This simplfies to 25+25=c². Now you simplify again to get 50=c². Finally you have to square root everything because the equation can't end in c², it has to be the most simplified it can be. This equals ≈7.1
