Answer:

217.1 lbs

Step-by-step explanation:

I did set up cross multiplication using the height/weight ratio.

68/205 and 72/?.

72*205=14760

14760/68=217.05

Then I rounded to get 217.1 lbs

If the mean of the data is 2.89, then the mean absolute deviation, variance, and standard deviation will be 0.67, 0.61, and 0.78 respectively.

Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, and summarise the data.

The data set is given below.

{$2.79, $1.99, $4.29, $2.49, $2.29, $3.49}

Then the mean value of the data will be

[tex]\mu = \dfrac{{2.79+ 1.99+ 4.29+ 2.49+ 2.29+ 3.49}}{6} \\\\\mu = \$ 2.89[/tex]

Then the mean absolute deviation will be

[tex]\rm MAD = \dfrac{1}{N} \Sigma _{i=1}^N |x_i - \mu|\\\\MAD = \dfrac{1}{6} (|2.79 - 2.89| + |1.99-2.89| + ... +|3.49-2.89|)\\\\MAD = 0.6667 \approx 0.67[/tex]

Then the standard deviation will be

[tex]\rm \sigma = \sqrt{\dfrac{\Sigma _{i=1}^N (x_i - \mu)^2}{N} }\\\\\sigma = \sqrt{\dfrac{(2.79-2.89)^2 + (1.99 - 2.89)^2 + .... + (3.49 - 2.89)^2}{6}}\\\\\sigma = \sqrt{0.61}\\\\\sigma = 0.78[/tex]

Then the variance will be

[tex]\sigma ^2 = (\sqrt{0.61})^2\\\\\sigma ^2 =0.61[/tex]

Answer:

a=9, b=45, c=31.5, d=18, f=27

Step-by-step explanation:

To find the value of a, you can take 72-54=18 and do 18/2=9

a=9

To find the value of b, you can multiply the three a's. 27 is the product of the 3 a's. Next, you will do 72-27 to find the value of b

b=45

To find the value of c, you can take 9 and subtract it from 72, or in other words: 72-9=63. You will then divide 63/2 to find the value of c

c=31.5

To find the value of d, you can multiply (9*4)=36. You can then take 72-36 and get 36. To find the value of d, you will then divide 36/2.

d=18

To find F, you are given a clue that 1 a and 1 d together=f.

9+18=f

f=27

Answer:

a=9

b=36

c=45

d=31.5

f=40.5

Considering the volume of the cube, it is found that it has a diagonal with a length of 12 inches.

The volume of a cube of side length a is given by:

V = a³.

The diagonal is given by:

[tex]D = \sqrt{3}a[/tex]

In this problem, the volume is of 340 in³, hence:

[tex]a³ = 340 \rightarrow a = \sqrt[3]{340} \rightarrow a = 6.98[/tex]

Hence, the diagonal is given by:

[tex]D = \sqrt{3} \times 6.98 = 12[/tex]

Answer:

$8.10 in profit

Step-by-step explanation:

First convert from yards to feet. 50 yards is equal to 150 feet. To find the unit price for how much they bought it for divide $13.50 / 150 to find that they bought the satin for 9 cents a foot.

Next find how much they sold it for. To find this divide $0.80 / 5 to find that they sold the satin for 16 cents a foot.

To find the profit for 45 yards, convert 45 yards to feet which is 135 feet. Then multiply this by the unit price for sales, 135 * $0.16 to get $21.60

To find the profit subtract the amount they spent on the fabric by the amount they made.

21.60-13.50 = $8.10

The number of cookies left in the basket after everyone has eaten out of the cookies is 7.

The first step is to convert the fractions to percentages.

1/6 x 1000 = 16.67%

1/5 x 100 = 20%

Now determine the sum of the percentages of the cookies eaten : 10% + 30% + 16.67 + 20% = 76.67%

Determine the percentage of cookies left = 100 - 76.67 = 23.33%

Number of cookies left = (23.33 / 100) x 30 = 7

Plot box-and-whisker graph:

Answer:

[tex]\textsf{Perpendicular to given line}:y=-3x+14[/tex]

[tex]\textsf{Parallel to given line}: y=\dfrac13x-\dfrac83[/tex]

Step-by-step explanation:

Rewrite the given equation to make y the subject:

[tex]\begin{aligned}-3x+9y &=5 \\ \implies 9y &=3x+5 \\ \implies y &=\dfrac13x+\dfrac59\end{aligned}[/tex]

Therefore, the slope of the given equation is [tex]\frac13[/tex].

If two lines are perpendicular to each other, the product of their slopes will be -1.  Therefore, the slope (m) of the line that is perpendicular to the given line is:

[tex]\begin{aligned}m \times \dfrac13 & =-1\\ \implies m & =-3\end{aligned}[/tex]

To find the equation of the line, substitute the found slope (-3) and the point (5, -1) into the point-slope form of a linear equation:

[tex]\begin{aligned}y-y_1 & =m(x-x_1)\\ \implies y-(-1) &=-3(x-5) \\ y+1 & =-3x+15 \\ y &=-3x+14\end{aligned}[/tex]

If two lines are parallel to each other, their slopes will be the same.  Therefore, the slope (m) of the line that is parallel to the given line is [tex]\frac13[/tex]

To find the equation of the line, substitute the slope ([tex]\frac13[/tex]) and the point (5, -1) into the point-slope form of a linear equation:

[tex]\begin{aligned}y-y_1 & =m(x-x_1)\\\\ \implies y-(-1) &=\dfrac13(x-5) \\\\ y+1 & =\dfrac13x-\dfrac53 \\\\ y &=\dfrac13x-\dfrac83\end{aligned}[/tex]

Slope =m=1/3

Answer:

The correct answer is option D, 20ft

Step-by-step explanation:

After drawing the picture below, you can just use pythagorean theorem to solve for the diagonal, or the hypotenuse in this case;

(Length)² + (Width)² = (Diagonal)²

(16)² + (12)² = (Diagonal)²

256 + 144 = (Diagonal)²

400 = (Diagonal)²

[tex]\sqrt{400}[/tex] = [tex]\sqrt{Diagonal^{2} }[/tex]

20 = Diagonal

Hope this helps!

Answer:

D. 20 ft

Step-by-step explanation:

Use pythagorus! We can imagine the rectangle is split into 2 equal triangles, one side of the triangle being 12, and the width being 16.

Pythagorus theorum is used to calculate the hypotenuse (long side) of a right-angled triangle. This is the formula:

[tex]\sf{a^{2}+b^{2} = c^{2} }[/tex]

So, we do 12^2 (squared) + 16^2 =

144 + 256 = 400

Now, we have to find the square root of 400, which is equal to

20

So our answer is 20ft

The additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year, option (b) is correct.

It is defined as the interest on the based on the principal amount, it does not include the compounded amount. The interest calculate on the initial amount or borrowed amount.

We know the formula for the simple interest is given by:

I = PRT

Where I is the simple interest.

P is the principal amount

R is the rate of interest

We have in the question:

I = $180

R = 2% = 0.02

T = 1  year

Put the above values in the formula, we get:

180 = P(0.02)(1)

P = $9000

The additional interest Benson pay each month is:

= 9000/12

= $750

Thus, the additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year option (b) is correct.
