number?

O 120

O 10

030

**Answer:**

12 10 12 30

**Step-by-step explanation:**

eso se devide y es 1.030

The sum of the four numbers divided by 4 is equal to the mean.

the sum/4 = mean

(12 + 50 + 48 + n)/4 = 30

(110 + n)/4 = 30

(110 + n) = 30 × 4

(110 + n) = 120

n = 120 - 110

n = 10

2y=128, then the value of y is:

y = 64.

**Step-by-step explanation:**

What is 481 ÷ 9 = because i’ve been getting the answer wrong?

**Answer: 53.44 **

**Step-by-step explanation:**

**Answer:**

53.4 repeating

**Step-by-step explanation:**

Step 1:Start by setting it up with the divisor 9 on the left side and the dividend 481 on the right side like this: 9⟌481

Step 2:The divisor (9) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top: 0 9⟌481

Step 3:Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend. 0 9⟌481 0

Step 4:Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below. 0 9⟌481 -0 4

Step 5:Move down the 2nd digit of the dividend (8) like this: 0 9⟌481 -0 48

Step 6:The divisor (9) goes into the bottom number (48), 5 time(s). Therefore, put 5 on top: 05 9⟌481 -0 48

Step 7:Multiply the divisor by the result in the previous step (9 x 5 = 45) and write that answer at the bottom: 05 9⟌481 -0 48 45

Step 8:Subtract the result in the previous step from the number written above it. (48 - 45 = 3) and write the answer at the bottom. 05 9⟌481 -0 48 -45 3

Step 9:Move down the last digit of the dividend (1) like this: 05 9⟌481 -0 48 -45 31

Step 10:The divisor (9) goes into the bottom number (31), 3 time(s). Therefore put 3 on top: 053 9⟌481 -0 48 -45 31

Step 11:Multiply the divisor by the result in the previous step (9 x 3 = 27) and write the answer at the bottom: 053 9⟌481 -0 48 -45 31 27

Step 12:Subtract the result in the previous step from the number written above it. (31 - 27 = 4) and write the answer at the bottom. 053 9⟌481 -0 48 -45 31 - 27 4

You are done, because there are no more digits to move down from the dividend.The answer is the top number and the remainder is the bottom number.Therefore, the answer to 481 divided by 9 calculated using Long Division is: 53 4 Remainder

Peter transports metal bars in his van.

The van has a safety notice: "Maximum Load 1200 kg".

Each metal bar has a label: "Weight 60 kg".

For safety reasons, Peter assumes that:

1200 is rounded correct to 2 significant figures, and

60 is rounded correct to 1 significant figure.

Calculate the greatest number of bars that Peter can safely put into the van if his assumptions are

correct.

**Answer:**

17 bars

**Step-by-step explanation:**

Peter wants to compute the **maximum number of bars** he can **load safely** if the load limit of **1200 kg** and the bar weight of **60 kg** are each rounded to the number of **significant digits** those numbers have.

The error in a rounded number is assumed to be as much as half of the least significant digit of the number.

Peter's load limit may actually be as low as ...

1200 kg - (1/2)(100 kg) = 1150 kg . . . . . . . 1200 is rounded to nearest 100

Peter's bar weight might be as high as ...

60 kg + (1/2)(10 kg) = 65 kg . . . . . . . . . . . 60 is rounded to nearest 10

Safe loadingIf Peter has maximum-weight bars and does not want to exceed the minimum his load limit might be, the number of bars he can load is ...

(1150 kg) / (65 kg/bar) ≈ 17.7 bars

**The greatest number of bars Peter can load safely is 17**.

Step 1: Determine number of edible portions (EP)

Step 2: Determine food cost per portion

1. The **number** of edible portions (EP) is 64.

2. The food **cost** per portion = $0.75 per portion.

The **number **of edible portions can be determined by first **converting** the case weight in pounds into ounces.

There are 16 ounces in a pound. 20 pounds will equal 320 ounces by **multiplication** (16 x 20).

Then, **divide** 320oz by 5oz to determine the number of portions.

Yield: 90%

Purchase Unit: 10 boxes = 1 case

Case Weight: 20 lbs

Case Cost: $48.00

Portion Size: 5oz

1lb = 16oz

20lbs = 320oz (20 x 16)

Edible portions (EP) = 64 (320oz/5oz)

Food cost per portion = $0.75 per portion ($48/64).

Thus, the number of edible portions is 64 with the food cost per portion as $0.75.

If a new van is valued at $34,600, what will its value be in 3 years if it depreciates 14.2% each year?

**Answer:**

**The answer is $21,854. 35**

**Step-by-step explanation:**

**rate = 14.2%**

**Time = 3 years**

**Value = 34600**

**V = (1-r)^t**

**V=34600(1-0.142)^3**

**V=34600 (0.858)^3**

**V=$21,854.35**

34600 * (1-0.142)^3 = 21854.35

since W is the midpoint, that simply means that both halves are twins, so

The **length of segment **VY, represented by "a," is 25x - 21.

To find the length of segment VY, we can use the fact that W is the midpoint of VY. The midpoint of a line segment divides it into two equal parts. Therefore, the length of VW plus the length of WY equals the length of VY.

Let VY be represented by "a." Then, according to the midpoint property:

VW + WY = VY

Substitute the given** expressions** for VW and WY:

(9x + 7) + (16x - 28) = a

Now, combine like terms:

25x - 21 = a

A study was performed with a random sample of 5 people from a certain city. What population would be appropriate for generalizing conclusions from the study, assuming the data collection methods used did not introduce biases?

The standard deviation is a statistic that describes the degree of volatility or dispersion in a set of numerical values. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established **mean**.

High sample size is typically crucial in order to be able to draw generalizations from a sample, aside from avoiding bias. Since the sample size is modest, it will thus be possible to draw general conclusions about the study utilizing a larger sample, in my opinion.

The size of the sample has a significant impact on whether an experiment is legitimate. The central limit theorem states that as sample size rises, the sample mean approaches the population** means** value.

Because of this, generalizing from just five samples regarding a population of city dwellers won't produce a result that can be generalized.
