Horse = 10
Horseshoe = 4
Boots = 2
1+10*2 = 21
Answer: $1450
The profit that is gained from the production and selling of the jeans is given to be calculated through the the equation,
P = 20x - 50
For 75 jeans, we just have to substitute 75 to the x's of the equation. This then becomes,
P = 20(75) - 50 = 1450
Thus, the company will make a profit of $1450 by production of 75 jeans.
Step-by-step explanation:
Answer:
f^-1(x) = 1/5x + 1/5
Step-by-step explanation:
Switch the x and y values:
y = 5x - 1
x = 5y - 1
Put the equation back into y = form:
x = 5y - 1
x + 1 = 5y
1/5x + 1/5 = y
y = 1/5x + 1/5
f^-1(x) = 1/5x + 1/5
Answer:
4miles, because it would just be 12 divided by 3.
Step-by-step explanation:
We are given the following values:
n = number of samples / cars = 1,698
p = probability of each success = 0.07
The standard deviation (σ) is calculated using the
formula:
σ = sqrt [n p (1 – p)]
σ = sqrt [1,698 (0.07) (1 – 0.07)]
σ = 10.51
The mean (x) is:
x = n p
x = 1,698 (0.07)
x = 118.86 car accidents
The quartiles are:
1st quartile = x - 2σ to x – σ
1st quartile = 118.86 – 2 (10.51) to 118.86 –
10.51
1st quartile = 97.84 to 108.35
(97.84<Q1<108.35)
3rd quartile = x to x + σ
3rd quartile = 118.86 to 118.86 + 10.51
3rd quartile = 118.86 to 129.37
(118.86<Q3<129.37)
