find four consecutive even integers such that the sum of the third and fourth is 6 less than four times the first

lisabon 2012 [21]

Answer:

The numbers are 2, 4, 6 and 8

Step-by-step explanation:

let the four numbers be x, y, z and l respectively

then:

x+y+z+l

(z+l)–6=4x

since they are all four consecutive even integers

then y=x+2

z=y+2=x+4

l=z+2=x+6

since (z+l)–6=4x

then ((x+4)+(x+6))–6=4x

2x+4=4x

4=4x–2x

4=2x

2=x

Weekly demand for a particular item averages 30 units, with a standard deviation of 4. This item is managed with a fixed-order-i

aivan3 [116]

Answer:

(B)93

Explanation:

Since we are using a fixed-order-interval model,

The Amount to Order=Expected Demand During protection Interval+Safety Stock-Amount at Hand

$=d(OI+LT)+z\sigma_{d}\sqrt{OI+LT}-A$

Where:

d=weekly demand

OI=Order Interval

LT=Lead Time

z=Standard Deviation of Desired Service Level

$\sigma_{d}$ =Standard Deviation of weekly Demand

A= Amount at Hand

$=d(OI+LT)+z\sigma_{d}\sqrt{OI+LT}-A$

$[30(3 + 1)] + [1.964*4*\sqrt{3 + 1} - 43$

$= 120 + 15.712 - 43 = 92.7$

Find (-3/7) divided (-1 1/14)

Andrews [41]

Answer:

2/5

Step-by-step explanation:

first, we convert the mixed fractions to improper fractions,

$-1\frac{1}{14}=\frac{15}{14}$

so then we find what $-\frac{3}{7}$ $\div$ $-\frac{15}{14}$

$-\frac{3}{7}$ $\div$ $-\frac{15}{14}$ = $-\frac{3}{7} * -\frac{14}{15}$

and that equals $\frac{3*14}{7*15}$ , which equals $\frac{42}{105}$ . We can simplify that to 2/5
