Answer:
B and C
Step-by-step explanation:
To figure out the average of all of the scores, you add all of the numbers together and then divide by how many numbers there are. The average shows about how well they did. Anne's friends average was 90 and was higher than Joan's friends average which was 75. Then the lowest score was definitely 78. So the answer would be B and C.
Answer:
612 Hz.
Step-by-step explanation:
The frequency of the sound will be proportionally higher when coming towards you. The increase is related to the speed of the train.
So the frequency will be:
580 + (580 / 343) * 18.8
= 612 Hz.
This is called the Doppler effect.
(5 x 6) + 7 = 37
(5 + 7) x 6 = 72
(6 - 7) / 5 = -1/5
Answer:
g(x) = 1/4 f(x)
Step-by-step explanation:
f passes through the origin and has a slope of 1.
f(x) = x
g passes through the origin and has a slope of 1/4.
g(x) = 1/4 x
Substituting:
g(x) = 1/4 f(x)
