So approximately 14.5% of the scores are higher than 600. This means in a sample of 7500, one could expect to see
scores above 600.
500 KM because 150•100 (150 x 100/30 that's the total) 15,000/30=500 KM hope his helps
Answer:
The answer is “B”
Step-by-step explanation:
Group and factor out the greatest common factor (GCF), then combine.
The answer to this problem is A
The vertex is at (2, 5).
To find the vertex, we first find the axis of symmetry; this is given by
x = -b/2a
For our equation, b = -16 and a = 4:
x = -(-16)/2(4) = 16/8 = 2
We substitute this back into our equation:
y = 4(2)² - 16(2) + 21 = 4(4) - 32 + 21 = 5
Therefore the vertex is at (2, 5).
