Answer:

Hello,

0,4925...

Step-by-step explanation:

A geometric random variable X with parameter p has probability function:

$f(x)=p*(1-p)^x\ where\ x=0,1,2,3....\\\\mean=\dfrac{1-p}{p} =\dfrac{1-0.67}{0.67} =0.4925...$

Madisyn is planting crops in a triangular garden. She is trying to find the amount of fencing

MrRissso [65]

Answer:

Fencing needed = 20.8 units

Step-by-step explanation:

From the figure attached,

Given: Triangle ABC with vertices A(0, 6), B(6, 5) and C(5, -1).

We have to find the length of fence required to cover the triangular garden.

Amount of fencing required = Perimeter of the triangular garden

Perimeter of the garden = AB + BC + AC

Formula to get the distance between A and B,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

AB = $\sqrt{(0-6)^2+(6-5)^2}$ = $\sqrt{37}$

BC = $\sqrt{(6-5)^2+(5+1)^2}$ = $\sqrt{37}$

AC = $\sqrt{(0-5)^2+(6+1)^2}$ = $\sqrt{74}$

Perimeter = $\sqrt{37}+\sqrt{37}+\sqrt{74}$

= 6.08 + 6.08 + 8.60

= 20.76

≈ 20.8 units

Therefore, amount of fencing required to cover the triangular park is 20.8 units.

Plz help HW plz help HW plz help HW

jarptica [38.1K]

Answer:

55°, 70°, 55°

Step-by-step explanation:

Δ MHP is right triangle, therefore

m∠P = 90° - 35° = 55°

ΔMNP is isosceles triangle as MN = MP, therefore

m∠N = m∠P = 55°

m∠NMP = 180° - 2*55° = 70°
