Answer:
To begin solving we subtract 3 from each side
4w = -10
Next, we divide both side by 4
w = -2.5

Z = ( X - Mean ) / SD
z = ( 646 - 597 ) / 39
z = 49/39 = 1.25
With the z-score table:
for z = 1.25, p = 0.8944 ( probability that the cost will be lower than $646 )
1 - 0.8944 = 0.1056
Answer: <span>The probabilit</span>y is 0.1056
Volume=(4/3)pi(r^3)
radius=1/2diameter
d=36
radius=1/2 36
radius=18
subsitute
volume=4/3 pi 18^3
volume=4/3 pi 5832
volume=23328/3 pi
volume=7776pi
aprox pi to 3.14
volume=7776 times 3.14
volume=24416.64
answer is 24416.64 yd^3
Answer:
-3x
Step-by-step explanation:
Okay so you need to start off by using the distributive property, meaning you are going to multiply -2 by both items within the parentheses. this gives you -2x + 10 = -14. from here you want to isolate x, so you’ll subtract both sides by 10 to move it to the other side. this gives you -2x=-24. then you’ll divide both sides by -2 to completely isolate x. this gives you x=12. does that make sense?
