Answer:
1.89 is the standard deviation of households who own a riding mower
Step-by-step explanation:
Let the random variable X denote the number of households owning a riding lawn mower. From the given information, X will be a Binomial random variable with parameters; n = 17 and p = 30% = 0.3
The standard deviation of X;
Answer:
-1
Step-by-step explanation:
we would use the slope formula which is y2-y2/x2-x1
so 3-4/5-4= -1
5/6 = .83333333(repeating)
the 200th digit is 3
Add EF and DE together to equal 32
2x-10 + 4x = 32
Combine like terms;
6x-10 = 32
Add 10 to each side:
6x = 42
Divide both sides by 6:
x = 42/6
X = 7
EF = 2x-10 = 2(7)-10 = 14-10 = 4
DE = 4x = 4(7) = 28
For this case, what we should do is use the given equation.
We have then:
trade discount = rate × list price
Where,
list price = 1000 $
rate = 20 * (1/100) = 0.2
Substituting values we have:
trade discount = (0.2) * (1000)
trade discount = $ 200
Answer:
The amount of the discount is $ 200
