Answer:
a- this data shows us how many miles they drive per hour
for example: if they drive for 1hour then they would have driven 12 miles in distance
b- motor bike...?
Third Period: 4, 5, 3, 4, 2, 3, 4, 1, 8,
2, 3, 1, 0, 2, 1, 3
Measures of central tendency are methods
to which an investigator can locate the most central value, or the reoccurring or
frequent most value in the set of parameter or statistic. There are three:
Mean. Is the average of the data values
Median. The middlemost value or digit in
the data set
Mode. The determining the most frequent
parameter
To identify which of these three suits
the given, arranging them first is a must. Ascending to descending.
Third Period: 0,1,1,1,2,2,2,3,3,3,3
4,4,4,5,8,
The best is mode, why? Because if you
observe there is a number most frequent in the data value and it is the fastest
way.
Mode = 3
Answer:
Step-by-step explanation:
Demand = 19,500 units per year (D)
Ordering cost = $25 per order (O)
Holding cost = $4 per unit per year (C)
a) 

= 
= 
= 493.71044 ≈ 494
b) Annual holding cost = 
= 
= 4 × 247
= 988
c) Annual ordering cost = 
= 
= 25 × 39.47
= 986.75
AOQ = 494
Annual holding cost = 988
Annual ordering cost = 986.75
The product of the two is 0, so one of them have to equal 0 as any number multiplied by 0 is 0.
First solution: x - 4 = 0
If x - 4 = 0, then x = 4. So the first solution for <em>x </em>is 4.
Second Solution: -5x + 1 = 0
Solving...
-5x + 1 = 0
-5x = -1
x = -1/-5
x = 1/5 or 0.2
So x = 0.2 and 4
Answer:
(2x-1)(2x+1)(x^2+2) = 0
Step-by-step explanation:
Here's a trick: Use a temporary substitution for x^2. Let p = x^2. Then 4x^4+7x^2-2=0 becomes 4p^2 + 7p - 2 = 0.
Find p using the quadratic formula: a = 4, b = 7 and c = -2. Then the discriminant is b^2-4ac, or (7)^2-4(4)(-2), or 49+32, or 81.
Then the roots are:
-7 plus or minus √81
p= --------------------------------
8
p = 2/8 = 1/4 and p = -16/8 = -2.
Recalling that p = x^2, we let p = x^2 = 1/4, finding that x = plus or minus 1/2. We cannot do quite the same thing with the factor p= -2 because the roots would be complex.
If x = 1/2 is a root, then 2x - 1 is a factor. If x = -1/2 is a root, then 2x+1 is a factor.
Let's multiply these two factors, (2x-1) and (2x+1), together, obtaining 4x^2 - 1. Let's divide this 4x^2 - 1 into 4x^4+7x^2-2=0. We get x^2+2 as quotient.
Then, 4x^4+7x^2-2=0 in factored form, is (2x-1)(2x+1)(x^2+2) = 0.
