Note: I just noticed that you only have one negative sign. If you mean to put -9, change the sign to positive. If not, leave the answer.
Note the equal sign. what you do to one side, you do to the other. Isolate the x. First, multiply 3 to both sides
-x/3(3) = 9(3)
-x = 9(3)
-x = 27
Next, to isolate the x, divide -1 from both sides
-x/-1 = 27/-1
x = 27/-1
x = -27
-27 is your answer for x.
hope this helps
To solve this, we use the z-test.
z = (x – u) / σ
when x = 450
z = (450 – 550) / 100
z = -1
We use the standard distribution tables to find for P.
P = 0.1587
Since we are looking for values greater than x = 450,
therefore:
1 – 0.1587 = 0.8413
This means that 84.13% have bladder volume larger than 450
mL.
Answer:
28feet
Step-by-step explanation:
The height of the balloon is given as h(t) = -16t² + 40t + 12 at 2 seconds, the height is 28 feet
15,049 x .21 = 3,160
subtract: 15,049 - 3,160 = 11, 888
Answer:
7.000
Step-by-step explanation:
6.877 so its talking about the 8 so its greater than 5 so its 7 or 7.000
