ANSWER

The missing probability is 0.15

EXPLANATION

From the given probability distribution table.

P(1)=0.30

P(2)=0.40

P(3)=0.15

P(4)=?

For for this to represent a probability distribution function,then the sum of all the probabilities must be equal to 1.

P(1)+P(2)+P(3)+P(4)=1

This implies that,

0.30+0.40+0.15+P(4)=1

0.85+P(4)=1

P(4)=1-0.85

P(4)=0.15

Therefore the missing probability is 0.15

Use the Law of Sines to solve the triangle. Round your answers to two decimal places. A = 38°, B = 73°, c = 23.6 C = ° a = b =

Sonja [21]

Answer:

The solution for the triangle is 1.62 a = 1.04 b = 0.59 c

Step-by-step explanation:

Given as :

The value of ∠A = 38°

The value of ∠B = 73°

The value of ∠C = 23.6°

Now, Applying Law of Sines

I.e $\frac{a}{Sin A}$ = $\frac{b}{Sin B}$ = $\frac{c}{Sin C}$

Or, $\frac{a}{Sin 38°}$ = $\frac{b}{Sin 73°}$ = $\frac{c}{Sin 23.6°}$

Or, $\frac{a}{0.6156}$ = $\frac{b}{0.9563}$ = $\frac{c}{0.4003}$

Or, 1.62 a = 1.04 b = 0.59 c

So, The solution for the triangle is 1.62 a = 1.04 b = 0.59 c

Hence The solution for the triangle is 1.62 a = 1.04 b = 0.59 c Answer

The equation t^3=a^2 shows the relationship between a planet’s orbital period, T, and the planet’s mean distance from the sun, A

ankoles [38]

Answer:

2√2

Step-by-step explanation:

We can find the relationship of interest by solving the given equation for A, the mean distance.

<h3>Solve for A</h3>

$T^3=A^2\\\\A=\sqrt{T^3}=T\sqrt{T}\qquad\text{take the square root}$

<h3>Substitute values</h3>

The mean distance of planet X is found in terms of its period to be ...

$D_x=T_x\sqrt{T_x}$

The mean distance of planet Y can be found using the given relation ...

$T_y=2T_x\\\\D_y=T_y\sqrt{T_y}=2T_x\sqrt{2T_x}=(2\sqrt{2})T_x\sqrt{T_x}\\\\D_y=2\sqrt{2}\cdot D_x$

The mean distance of planet Y is increased from that of planet X by the factor ...
