The ordering cost using the Lot-for-Lot method is 900.06.

The ordering cost using the Lot-for-Lot method will be calculated thus:

C = Q/2(H) + D)Q(S)

C = 450/2(4) + 100/450(3)

C = 450(2) + 30/45

C = 900 + 0.7

C = 900.7

The ordering cost using Wagner-Whitin algorithm will be:

= 300 + 900 + 300 + 1700 + 2150 + 600

= 5750

The ordering cost using fixed order quantity will be:

= 6/(300 + 450 + 100 + 450 + 450 + 100)

= 6/1850

= 0.00324

Answer:

It's D) 95%

Step-by-step explanation:

It's the correct answer

The percentage of the times are between 2 hours and 4 hours is 45.5%.

Standard deviation is the positive square root of the variance. Standard deviation is one of the basic methods of statistical analysis. Standard deviation is commonly abbreviated as SD and denoted by 'σ’ and it tells about the value that how much it has deviated from the mean value.

Given that, μ=3 hour, σ=0.5 and x1=2 hours and x2=4 hours.

We know that, Z=(x-μ)/σ

Here, Z1=(2-3)/0.5

Z1=-2 = -0.2275

Z2=(4-3)/0.5

Z2=2 = 0.2275

= 0.2275-(-0.2275)

= 0.2275+0.2275

= 0.455

= 45.5%

Therefore, the percentage of the times are between 2 hours and 4 hours is 45.5%.

Step-by-step explanation:

There are two pairs of congruent angles, meaning the triangles are similar by AA.

It is true that based on the given information triangle RST is similar to triangle UVW by the AA similarity postulate.

Similar triangles are triangles that have the same shape but are different in size. More specifically, two triangles are similar if their corresponding angles are congruent and their corresponding sides are in proportion.

Here,
Since a figure is given with two triangles, RST and UVW.
From the figure, we can see that there are two angles that are equal, are given as;

∠R=∠U    [measure is 67°]

∠T=∠W    [measure is 90°]

Thus, it is true that based on the given information triangle RST is similar to triangle UVW by AA similarity postulate.

Step-by-step explanation:

Natural log and the number 'e' are inverse to each other. Therefore, if you take the natural log of both sides, the exponential cancels and leaves 'x' isolated:

[tex]ln(e^x)=ln(15.29)[/tex]

[tex]x=ln(15.29)[/tex]

Let's solve for x

So natural logarithm on both sides

Answer:

9.1s

Step-by-step explanation:

Since we know that velocity is uniformly decelerating, we can take the average velocity: Letting Vf equale 0 /ms, we get 1/2 21.8ms or 10.9ms. Now we know V = D/T and rearranging this gives T = D/V. Substitute our velocity of 10.9m/s for V and 99m for D: T = 99m/ 10.9ms. finally we get T = 9.1s

The time in which Anny drives in the rain is 90 minutes. This is calculated by using the speed-distance-time formula.

Speed is the ratio of distance traveled to the time taken for traveling.

Speed=distance/time

Unit: m/s

It is given that,

Anny drives at a speed of 50 miles per hour if it is not raining and drives at a speed of 30 miles per hour.

Today she drove in the sun in the morning and the rain in the afternoon, for a total of 120 miles in 180 minutes.

Consider x be the time required to drive not in the rain and y be the time required to drive in the rain

So, the distance covered (not in the rain) = 50x (since the speed is 50 mile/h), and the distance covered (in the rain) =30y (since the speed is 30 miles/h)

Therefore, the total distance covered both in rain and without rain is:

50x+30y=120 (since the total distance she drove is 120 miles)

And the total time required for driving in rain and without rain is:

x + y=3 (since 180 minute = 3 hours)

On solving the above equations we get,

x=[tex]\frac{3}{2}[/tex] and y=[tex]\frac{3}{2}[/tex]

Then,

y=[tex]\frac{3}{2}[/tex]×60(minute)=90 minute

Therefore, the time taken for her to drive in rain is 90 minutes.

Answer:

86°

Step-by-step explanation:

Two sides of the triangle are equal

=> ∠A = ∠C

And since ∠A = 47°

=> ∠C = 47° & ∠B = x°

Now, according to Angle sum property of a triangle

=> ∠A + ∠B + ∠C = 180°

=> 47° + x + 47° = 180°

=> 94° + x = 180°

=> x = 180 - 94 = 86°

Therefore x = 86°
