Answer:
<u>The equation is x = y * 4/5 and US$ 12 would equal 15 Swiss Francs</u>
Step-by-step explanation:
<u>1. Let's review all the information provided for solving this question:</u>
1 US$ equivalent to 1 1/4 Swiss Franc
2. Let's write and solve a multiplication equation to find the amount of US$ that would equal 15 Swiss Francs
x = Amount of US$ equivalent
y = Amount of Swiss Francs
x = y /1.25
x = y / 5/4 (1.25 = 5/4)
<u>x = y * 4/5</u>
Now, let's replace with the real values:
x = 15 * 4/5
x = 60/5
<u>x = 12</u>
<u>US$ 12 would equal 15 Swiss Francs</u>
z < 1.25
I used mathaway it's correct
Answer:
C.
Step-by-step explanation:
The random variable W is Normal, with a mean of 28 ounces and a standard deviation of four ounces.
mean of total = 7+7+7+7 = 28
Variance of total = 4+4+4+4 = 16
SD of total = sqrt(16) = 4
Treat each of the rings as a point on a graph the point being (carat, Cost ring)
Knowing this we have 2 points which we need to form a line.
(0.3, 3457); (0.5, 4373) From this we can for a slope and then an equation.
slope =
(a) 64
divide 16 by .25 and you will get 64
(b) 34
multiply 40 by .85
