11.5 * 2.3 = large door size
large door size / 12 = large door size in feet
large door size in feet / 10 = how many large doors can be cut from the board. (you have to round it down if there's a decimal- no 1/2 doors.)
Answer:
n=42 adult men
Step-by-step explanation:
-The minimum sample size to get a desired margin of error, E is calculated using the formula:
-Given that , we can substitute to solve for n in the above formula:
Hence, the desired minimum sample size, n is 42 adult men.
I believe the problem ask for s which is the standard
deviation. We must recall that the formula for z statistic is stated as:
z = (x – x over bar) / s
Where,
z = z statistic = 2.5
x = sample value or sample score = 102
x over bar = the sample mean or sample average = 100
s = standard deviation = unknown
Rewriting the equation in terms of s:
s = (x – x over bar) / z
Substituting the given values into the equation:
s = (102 – 100) / 2.5
s = 0.8
Therefore the standard deviation s is 0.8

Answer:
4y = -3x - 48
Step-by-step explanation:
y - y1 = m(x - x1)
y1 = -9 x1= -4 m = -3/4
y -(-9) = -3/4(x -(-4)
y + 9 = -3/4(x + 4)
y + 9 = -3/4x -12/4
multiply through by 4
4y + 36 = -3x -12
4y = -3x -12-36
4y = -3x -48 in the form y = mx + c
