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 %

Good morning,
Answer:
Step-by-step explanation:
h = altitude
side = a
using Pythagorean theorem: in the right triangle:
h² = a² - (a/2)²
= a² - a²/4
= 3/4a²
= [(√3/2)×a]²
⇒ h = (√3/2)×a.

47 is added to a number ⇒ 47 + x
37 less than 7 times the number ⇒ 7x - 37
47 + x = 7x - 37
x - 7x = -37 - 47
- 6x = -84
x = -84 / -6
x = 14
The value of the unknown number is 14.
47 + x = 7x - 37
47 + 14 = 7(14) - 37
61 = 98 - 37
61 = 61
Answer:
The statement describes that:
A person can be 9595 percent sure that the mean drive through service period of this chain is between 164.5164.5 seconds and 168.3168.3 seconds.
5,4* 10^4 = 54000in 2012.
2013 = 54000*3 = 5,4*3* 10^4 = 162000 fishes. 1,62 *10^ 5
