Answer:

(3+p)

Step-by-step explanation:

solution

first expression=9-P^2

=3^2 - P^2

=(3+P) (3-p)

second expression=p^2 + 3p

= p(3+p)

Therefore lCM= (3+p)

At a Noodles & Company restaurant, the probability that a customer will order a nonalcoholic beverage is .42. Find the proba

pashok25 [27]

Answer:

0.497

Step-by-step explanation:

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

From the question :

n = 6 ; x = 3 ; p = 0.42

P(x = 3) +... P(x = 6)

P(x = 3) = 6C3 * 0.42^3 * (1 - 0.42)^(6-3)

P(x = 3) = 20 * 0.074088 * 0.195112

P(x = 3) = 0.28910915712

Then find p(x = 4).. + p(x = 6)

Using a calculator :

P(X >= x) = 0.497

The two triangles are similar by AAA property ie

Angle Angle Angle property

Let us name the two triangles as ABC and DEF

By observing the figure

mB=mE=90 (right angled triangle)

mA=mD (parallel lines property)

mC=mF (parallel lines property)

Therefore by AAA the two triangles are similar .

The diagram is given below.

LiRa [457]

Answer: $8\sqrt{5}$

Step-by-step explanation:

By the geometric mean theorem,

$\frac{y}{16}=\frac{4}{y}\\\\y^{2}=64\\\\y=8$

So, by the Pythagorean theorem,

$8^2 + 16^2 = x^2\\\\320=x^2\\\\x=\boxed{8\sqrt{5}}$
