Answer:
P>7
Step-by-step explanation:
1) Subtract 6 from both sides.
5p>41-6
2) Simplify 41-6 to 35.
5p>35
3) Divide both sides by 5.
p>35/5
4) Simplify 35/5 to 7.
p>7
Answer:
15.87% of blue whales eat more than 5,850 pounds of fish
Step-by-step explanation:
Mean = 5000
Standard Deviation = 850
We need to find P(x>5850) = ?
We can find using z-score
z = x - mean/ standard deviation
z = 5850 - 5000/850
z = 850/850
z = 1
Now, P(x>5850) = P(z>1)
Finding value of P(z>1) by looking at the z-score table
P(z>1) = 0.8413
The normal distribution gives area to the left , so subtracting it from 1 to gain the answer
1-0.8413 = 0.1587
Now, to find percentage multiply it with 100
0.1587 * 100 = 15.87 %
15.87% of blue whales eat more than 5,850 pounds of fish
Answer:
B
Step-by-step explanation:
180-150=30
angle 3 is a right angle so it equals 90
all triangles add up to 180
so 90 + 30 is 120
180-120=60
a line is 180 degrees
so the answer is 120 B
