Answer:
Choice C; The flight will be late on one of the three days.
Step-by-step explanation:
The flight is 75% of the time. This means that out of 4 flights, 3 are on time and the result of Franc's spinner should reflect this fact, i.e his spinner should give 75% probability of flights on time.
Choice A says the flight is on time 0% of the time, This is not true, therefore this is not a correct interpretation of the three spins.
Choice B says the flight is on time 100% of the time, This is not true, therefore this is not a correct interpretation of the three spins.
Choice C says the flight is on time 66% of the time, which is close to 75%. Therefore this choice is close and correct.
Choice D says the flight is on time 30% of the time, This is not true, therefore this is not a correct interpretation of the three spins.
Thus only choice C is correct.

Answer:
-40 °F = -40 °C
Step-by-step explanation:
(1) F = 1.8 C + 32
If the Fahrenheit and Celsius temperatures are the same, then
(2) F = C Substitute (2) into (1)
C = 1.8C + 32 Subtract 1.8 C from each side
C – 1.8 C = 32 Combine like terms
-0.8C = 32 Divide each side by -0.8
C = -32/0.8
(3) C = -40 Substitute (3) into (1)
F = 1.8(-40) + 32
F = -72 + 32
F = -40
So, -40 °F = -40 °C
The thermometer below shows that -40 °F = -40 °C.
Answer:
A. Matrix A
Step-by-step explanation:
When you put a systems of linear equations in matrix form, you take only the coefficients of the <em>xy </em>terms and sort them. <em>x</em> goes first, <em>y</em> comes after, and the numbers after the bars are the constants.
