get the total units made:
170 + 165 + 149 + 157 + 181 = 822 units.
Multiply by pay:
822 x 0.12 = $98.64
Answer:
You would expect 807 babies to weigh between 3 and 6 pounds.
Step-by-step explanation:
We are given that
Mean,
pounds
Standard deviation,
pounds
n=1500
We have to find how many would you expect to weigh between 3 and 6 pounds.
The weights for newborn babies is approximately normally distributed.
Now,





Number of newborn babies expect to weigh between 3 and 6 pounds
=
X=1
because you would add two to the other side and have 2x=2 divide by 2 and you would be left with x=1
Answer:
The y-intercept is the height of the candle before it was lit
Step-by-step explanation:
The y-intercept is at 0 on the x-axis meaning that not time has passed, so the candle is at its original height
Answer:
x=-3, y=-19
Step-by-step explanation:
we can solve by substitution.
y = 2x-1 we can derive from the second equation.
plugging it into the first equation, 2x -3(2x-1) = 15.
simplying, 2x-6x+3 = 15 --> -4x+3 = 15, -4x = 12, x = -3.
now we know x, so we can solve for y by plugging it into one of the equations. --> -3*-6+y = -1
simplify, 18+y = -1 --> y = -19.
