Answer:

The expression given in the question i.e  7.5 + n + 9.63 is equivalent to  n + 17.13 .

Step-by-step explanation:

As given the expression given in the question be as follow .

= 7.5 + n + 9.63

Now simplify the above it can be written as .

= n + 7.5 + 9.63

= n + 17.13

Therefore the expression given in the question i.e  7.5 + n + 9.63 is equivalent to  n + 17.13 .

4. The length of your rectangular vegetable garden
OleMash [197]

The area of a garden is the amount of space the garden occupies

<em>The area of the garden is (c) 375 ft^2</em>

The given parameters are:

<em />L = 15 \times W<em> --- Length equals 15 times width</em>

Perimeter=160

The perimeter of a rectangle is:

Perimeter= 2(L + W)

Substitute known values

160= 2(15 \times W + W)

Divide through by 2

80= 15 \times W + W

80= 15W + W

80= 16W

Divide through by 16

5= W

Rewrite as:

W =5

The area of a rectangle is:

Area = L \times W

Substitute L = 15 \times W

Area = 15 \times W \times W

Substitute W =5

Area = 15 \times 5 \times 5

Area = 375

Hence, the area of the garden is <em>(c) 375 ft^2</em>

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

How many intersections are there of the graphs of the equations below?
kipiarov [429]

Answer:

<u>The number of intersections = ∞</u>

Step-by-step explanation:

Given the system of equations:

0.5 x + 5y = 6

3x + 30y = 36

By multiplying the first equation by 6

∴ 6 (0.5 x + 5y) = 6 * 6

∴ 3x + 30y = 36

So, Those equations are "Dependent", because they are really the same equation, just multiplied the first equation by 6.

So, the two equations are identical

Therefore: <u>They have infinity number of solutions.</u>

<u>See the attached figure.</u>

0.5 x + 5y = 6 ⇒ in black color

3x + 30y = 36 ⇒ in red color

Insert 5 arithmetic means between -1 and 11
Anni [7]

Answer:

Step-by-step explanation:

-1 1 3 5 7 9 11

That's the answer. If you need a method or a formula, that's a little harder.

L = a + (n - 1)*d

a = -1

L = 11

n = 7

or n is the hard part. If you have 5 means, then you have 6 spaces. So n must be 7 in all

11 = -1 + (7 - 1)*d                   add 1 to both sides. Combine the brackets

11+1 = -1+1+ 6*d

12 = 6d                               divide by 6

12/6 = d

2 = d

What this tells you is that each term has 2 added to it to get to the next one.
