Answer:
The answer is 175.5.
Step-by-step explanation:
This is because 25% of $260 is $65. Then you must subtract that from the original price. $260 - $65 = $195. Then, it says '10% off the sale price'. The sale price is $195. 10% of this is 19.5. Finally, you subtract this from the $195, with a final amount of $175.50
Answer:
Given :The monthly demand for a product is normally distributed with mean = 700 and standard deviation = 200.
To Find :
1. What is probability demand will exceed 900 units in a month?
2. What is probability demand will be less than 392 units in a month?
Solution:
We are supposed to find probability demand will exceed 900 units in a month.
Formula :
We are supposed to find P(Z>900)
Substitute x = 900
Refer the z table.
P(Z<900)=0.8413
P(Z>900)=1-P{(Z<900)=1-0.8413=0.1587
So, the probability that demand will exceed 900 units in a month is 0.1587.
Now we are supposed to find probability demand will be less than 392 units in a month
We are supposed to find P(Z<392)
Substitute x = 392
refer the z table
P(Z<900)=0.0618
So, probability that demand will be less than 392 units in a month is 0.0618.
Answer:
x = 12
y = 12
z = 12
Step-by-step explanation:
The triangle with z as one of it's sides is a 30, 60, 90 triangle where the longest side of the triangle is 2x, the shortest side as x, and the middle side as x*sqrt of 3.
The shared line between the two triangle is 12 and z is 12*sqrt of 3
The left triangle is a 45, 45, 90 triangle where the 2 sides that look the same are the same and the hypotenuse is x sqrt of 2 so y is 12 and x is 12 sqrt of 2
2(x + a) = 4b
2x + 2a = 4b
2a = 4b - 2x
a = 2b - x
A thousand ways you could solve this, but generally need to understand 3 concepts to do so
1. interior angles of triangle add up to 180 degrees
2. law of sines
3. law of cosines
my personal suggestion
determine what angle A is, then use law of sines in order to determine side c
