If pq =23 and up=1/23 fund the value of u*q*v*p. Explain which properties you used.

Given that pq=23 and up=1/23

But question is asking to calculate value of u*q*v*p. which doesn't contains variable "p"

So it seems that you mistyped the equation up=1/23

it should be uv=1/23


Now i will show you how to evalueate u*q*v*p

In given equation pq=23, p and q are together so first we need to rearrange the letters

u*q*v*p

= u*v*q*p {commutative property of multiplication}

= u*v*p*q {commutative property of multiplication}

= (uv)*(pq) {applied parenthesis just for easiness}

Now plug the given values

= (23)*(1/23) {multiplication}

= 23/23 {division}

= 1

Hence final answer is 1.

The local supermarket buys lettuce each day to ensure really fresh produce. Each morning any lettuce that is left from the previ
jekas [21]

Given Information:

Cost price = $4

Selling price = $10

Salvage value = $1.50

Average demand = μ = 250 boxes

Standard deviation = σ = 34 boxes

Required Information:

Number of lettuce boxes = ?

Answer:

The supermarket should purchase 268 boxes  of lettuce

Step-by-step explanation:

The required number of lettuce boxes that supermarket should purchase is given by

Number of lettuce boxes = μ + (z*σ)

Where μ is the average demand of lettuce boxes, σ is the standard deviation, and z is the z-score which is given by

p = C_us/(C_us + C_os)

The z-score corresponding to probability p will be obtained.

The cost of under stocking is given by

C_us = Selling price - Cost price

C_us = $10 - $4

C_us = $6

The cost of over stocking is given by

C_os = Cost price - Salvage value

C_os = $4 - $1.50

C_os = $2.50

p = C_us/(C_us + C_os)

p = 6/(6 + 2.50)

p = 0.7058

p  = 70.58%

The z-score corresponding to 70.58% probability is approximately 0.54

Number of lettuce boxes = μ + (z*σ)

Number of lettuce boxes = 250 + (0.54*34)

Number of lettuce boxes = 250 + (18.36)

Number of lettuce boxes = 268.36

Number of lettuce boxes ≈ 268

Therefore, the supermarket should purchase 268 boxes of lettuce.

How to use z-table?

Step 1:

In the z-table, find the probability you are looking for and note down the two-digit number of the given row. (e.g 0.5, 2.2, 0.5 etc.)

Step 2:

Then look up at the top of z-table and note down the value in the column for the remaining decimal point in the range of 0.00 to 0.09.

Step 3:

Finally, add the numbers obtained from step 1 and step 2.

kvasek [131]

Answer:

Hello!!!

In this specific case the constant of proportionality is s (speed).

Step-by-step explanation:

The constant of proportionality stay "constant" (as the name suggests) in a certain case.

meaning, the speed itself remains constant at any given distance or time.

You can use the constant of proportionality and either distance or time to find the missing varliable since it remains constant.

you can also switch up the formula:

d=st

t=d/s

s=d/t

i really hope this helps!!!!!

Which choice is equivalent to the expression below √-12
kondaur [170]

Answer:

E

Step-by-step explanation:

using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}, hence

\sqrt{-12}

= \sqrt{4(3)(-1)} = \sqrt{4} × \sqrt{3} × \sqrt{-1} [\sqrt{-1} = i]

= 2i\sqrt{3} → E
