Answer:
Im pretty sure its graph A
Step-by-step explanation:
The robotic lander travel 1.5 * 10⁶ miles per day
Speed is the ratio of distance travelled to time taken. It is given by:
Speed = distance / time
Since it takes 200 days for a InSight robotic lander traveled from Earth to Mars.
The distance travelled per day = 3×10⁸ miles / 200 days = 1.5 * 10⁶ miles
The robotic lander travel 1.5 * 10⁶ miles per day

Answer:
So the idea is that we want to find the total number of ways that we can pick 7 diamonds (real or fake) from the 12 diamonds.
So as you said, 12 choose 7 = 792
Now we need the total number of ways that we can satisfy that of the 7 we picked, exactly three are real, but this also means that four are fake.
So to choose 3 real from 5 is 5 choose 3 = 10
And to choose 4 fake from 7 is 7 choose 4 = 35
3x10/792= 350/792= 175/396
Answer:
b
Step-by-step explanation:
In a 30-60-90 right triangle, the hypotenuse is twice the length of the short leg.
The hypotenuse is AB and is 18.
The short leg is BC and is 9.
The only choice with BC = 9 is b.
Answer: b
