It can be either B. 11 or C. -11
Answer:
27,29
Step-by-step explanation:
Let the two numbers be represented by x and y. We know they are consecutive odd numbers so we can write one of them, lets use y, as y = x+2
x+y=56
x+(x+2)=56
2x=54
∴x=27
y=x+2
y=27+2
y=29
∴ANSWER: (27,29)
The point where they intersect
As we know,
and
now, let's add them as shown ~
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 %
