Whats the total area of a covered box with a length of 4 ft, a width of 3 ft, and a height of 6 ft

Answers

The total area of the covered box is 108 square feet.

We have the specifications of the box -

length (L) = 4 ft

width (B) = 3 ft

height (H) = 6 ft

We have to find the total area of the box.

What is the formula to calculate the total surface area of a cuboid ?

The total surface area will be -

A = 2(LB + BH + LH)

Using the formula above, we get -

A = 2(4 x 3 + 3 x 6 + 4 x 6)

A = 2(12 + 18 + 24)

A = 2 x 54

A = 108 square feet

Hence, the total area of the covered box is 108 square feet.

Volume is "L x W x H". (Length x Width x Height)

The top and bottom will be 4 x 3 = 12 sq ft.

2 sides each 4 x 6 = 24 x 2 = 48 sq ft.

2 sides each 3 x 6 = 18 x 2 = 36 sq ft.

Area = 24 + 36 + 48 sq ft = 108 sq ft.

According to the Central Limit Theorem, a) in a sufficiently large random sample, the distribution of a random variable X, with mean μ and standard deviation σ, is a normal distribution with mean μ and standard deviation σ/sqrt(n)b) The Central Limit Theorem does not apply to heavily skewed distributions.
True or False?

Answers

The statement is True. According to the Central Limit Theorem, in a sufficiently large random sample, the distribution of a random variable X, with mean μ and standard deviation σ, is a normal distribution with mean μ and standard deviation σ/sqrt(n).

1. The Central Limit Theorem states that the distribution of the sample means of a large sample size will approach a normal distribution, regardless of the original distribution of the population from which the sample is drawn.
2. For a sufficiently large sample size, the mean of the sample means will approach the population mean (μ) and the standard deviation of the sample means will approach the population standard deviation divided by the square root of the sample size (σ/sqrt(n)).
3. Therefore, in a sufficiently large random sample, the distribution of a random variable X, with mean μ and standard deviation σ, is a normal distribution with mean μ and standard deviation σ/sqrt(n).

This is the case because the Central Limit Theorem states that the distribution of sample means is approximately normal, regardless of the original distribution of the population from which the sample is drawn.

True so there is the answer

Charlene is knitting a baby blanket. She wants its width, w, to be at least half its length, l. She estimates that she has enough yarn to put fringe around the blanket, as long as the perimeter of the blanket is no more than 180 inches. The system of inequalities shown represents the width of the blanket in inches, w, and the length in inches, l.w ≥ 0.5l

2l + 2w ≤ 180

Answers

W > 0.5L

Perimeter:
2L + 2W < 180
2L + 2(0.5L) < 180
2L + 1L < 180
3L < 180
÷3       ÷3
  L < 60

Length should be less than or equal to 60 inches while width should be greater than or equal to 30 inches.

The length, L should be less than or equal to 60 inches whereas the width, W should be greater than or equal to 30 inches.

What are inequalities?

Inequalities refers to a system of two or more quantities in which one quantity is greater than or less than the other.

Based on the data given:

W > 0.5L

Perimeter of the blanket is given as:

2L + 2W < 180

2L + 2(0.5L) < 180

2L + 1L < 180

3L < 180

L < 60

Therefore, the length, L should be less than or equal to 60 inches whereas the width, W should be greater than or equal to 30 inches.

1) 1st integer = x ; 2nd integer = x + 1
x + x + 1 = 73
2x = 73 - 1
2x = 72
2x/2 = 72/2
x = 36  
1st integer = x = 36
 2nd integer = x + 1 = 36 + 1 = 37

2) 1st integer = -x ; 2nd integer = -x + 1
-x + -x + 1 = -171
-2x +1 = -171
-2x = -171 - 1
-2x = -172
-2x/-2 = -172/-2
x = 86     
1st interger = -86 ;
2nd integer = -86 + 1 = -85  (integer closest to zero)

3) 1st integer = x ; 2nd integer = x + 1 ; 3rd integer = x + 2
x + x+1 + x+2 = 78
3x + 3  = 78
3x  = 78 - 3
3x = 75
3x/3 = 75/3
x = 25
1st integer = x = 25     (integer closest to zero)
2nd integer = x + 1 = 25 + 1 = 26
3rd integer = x + 2 = 25 + 2 = 27

4) 1st integer = x ; 2nd integer = x + 1 ; 3rd integer = x + 2
x + x+1 + x+2 = 261
3x + 3 = 261
3x = 261 - 3
3x = 258
3x/3 = 258/3
x = 86
1st integer = x = 86
2nd integer = x + 1 = 86 + 1 = 87 (middle number)
3rd integer = x + 2 = 86 + 2 = 88

5) 1st integer = -x ; 2nd integer = -x+1 ; 3rd integer = -x + 2
-x + -x+1 + -x+2 = -165
-3x + 3 = -165
-3x = -165 - 3
-3x = -168
-3x/-3 = -168/-3
x = 56
1st integer = -x = -56
2nd integer = -x+1 = -56 + 1 = -55
3rd integer = -x+2 = -56 + 2 = -54 (closest to zero)
