0.72 cents per Apple it's quite simple just divide 4.32 divided by 6
Answer:
A) x² + 2x + 6
B) x² + 2x - 7
C) ¼(x²+2x+1))
D) 6x²+12x+6
E) -x²-2x-1
Step-by-step explanation:
A) f(x) + 5 =x²+2x+1 + 5
= x² + 2x + 6
B) f(x)-8,=x^2+2x+1-8
= x² + 2x - 7
C) ¼f(x) = ¼(x²+2x+1)
D) 6f(x) = 6(x²+2x+1) = 6x²+12x+6
E) -f(x) = -(x²+2x+1) = -x²-2x-1
The mean ( average ) is given as 1200 hours.
The standard deviation is 200, sample size is 100.
Find the standard error:
√(200^2 / 100) = 20
Now calculate the confidence interval. For 95% the Z number is 1.96
Multiply Z by the standard error:
1.96 x 20 =39.2
Now find the range that the mean should be within:
1200 - 39.2 = 1160.8
1200 + 39.2 = 1239.2
The samples should be between 1160.8 and 1239.2 for a 95% confidence interval.
Since the average was 1050, which is below 1160.8 the bulbs are not in compliance.
The measurement of ∠KNL is 102°
First, you must set up an equation to find x.
Then, you must simplify both sides of the equation.
Next, subtract 3x on both sides.
Then, subtract 2 on each side.
Next, divide 2 on each side.
Now that we have the value of x, we can substitute it in for angle KNL.

Step-by-step explanation:
sin 25 = 15 / xz
xz = 15/ sin 25
xz = 35.49
tan w = 35.49 / 22
w =58.15
