Step-by-step explanation:

6,5,8,2,8,6,5,8,8

To find the mean you MUST add all of the numbers together

then divide by the number of numbers

this will be your mean

Then to find the absolute deviation you must find the absolute value of the numbers in this case they stay the same  since the absolute value is NEVER negative....

then you need to find the data value of the entire data set

then subtract the mean from that number!

Answer:

14

Step-by-step explanation:

The two points on y=5 are (4,5) and (10,5), which can be deducted if you draw a picture with (7,1) and y=5 on it. A vertical line through 7,1 and the line to "some" points on y=5 left and right of it have lengths 4 and 5 respectively.

Then I realized these were two 3,4,5 triangles! So the x coordinates must be at 7-3=4 and 7+3=10 respectively!

The sum of 4 and 10 is 14.

edit: seems to me the sum is 14 regardless of the length of 5??

Answer:

0.125 miles per gallon.

Step-by-step explanation:

After 200 gallons used the freight train has traveled 25 miles. This means that we need to divide both sides by 200 to get a singular gallon's worth of miles traveled. 200/200 is 1, and 25/200 is 0.125.

IF it were how many gallons per mile, you would divide both answers by 25 resulting in 8 gallons per mile.

Answer:

Yes, he will have enough paint to cover the tank with one layer of paint.

Step-by-step explanation:

We are given that Tublu buys a cylindrical water tank of height 1.4 m and diameter 1.1 m to catch rainwater off his roof. He has a full 2 liters tin of paint in his store and decides to paint the tank (not the base).

He uses 250 ml to cover 1 [tex]\text{m}^{2}[/tex].

From the question, it is clear the area of the tank which needs to be painted is the lateral surface area (because the base is not included).

The lateral surface area of the cylinder = [tex]2\pi rh[/tex]

where, r = radius of the cylinder =  [tex]\frac{\text{Diameter}}{2}[/tex]  = [tex]\frac{1.1 }{2}[/tex] = 0.55 m

           h = height of the cylinder = 1.4 m

           [tex]\pi[/tex] = 3.142 (given)

So, the lateral surface area of a cylindrical water tank = [tex]2 \times 3.142 \times 0.55 \times 1.4[/tex]

                                                                                         = 4.84 [tex]\text{m}^{2}[/tex].

Now, it is given in the question that; Tublu uses 250 ml to cover 1 [tex]\text{m}^{2}[/tex] area, this means that;

To cover 4.84 [tex]\text{m}^{2}[/tex] area, he will use paint = [tex]4.84 \times 250[/tex] = 1210 ml

Since he has a full 2 liters tin of paint in his store which is equal to 2000 ml but he need only 1210 ml of paint.

This means that yes, he will have enough paint to cover the tank with one layer of paint.

Answer:

[tex]x = 500[/tex]

Step-by-step explanation:

Given

[tex]log20x^3 - 2logx = 4[/tex]

Required

Solve for x

[tex]log20x^3 - 2logx = 4[/tex]

Using law of logarithm which says;

[tex]nlogx = logx^n[/tex]

The expression becomes

[tex]log20x^3 - logx^2 = 4[/tex]

Also, using laws of logarithm which says:

[tex]loga - logb = log\frac{a}{b}[/tex]

The expression becomes

[tex]log(\frac{20x^3}{x^2}) = 4[/tex]

[tex]log(20x) = 4[/tex]

Also, using laws of logarithm which says

[tex]If\ loga = b\\then\ a = 10^b[/tex]

The expression becomes

[tex]20x = 10^4[/tex]

[tex]20x = 10000[/tex]

Divide through by 20

[tex]\frac{20x}{20} = \frac{10000}{20}[/tex]

[tex]x = \frac{10000}{20}[/tex]

[tex]x = 500[/tex]

Answer:

Volume = 252π units³

Step-by-step explanation:

We have been given an obliques cylinder (a cylinder having its bases parallel to each other but are not aligned).

The volume of an oblique cylinder can be found similarly to that of a regular cylinder, with using the formula:

Volume = Base · Height

Where the height in the regular cylinder is taken as the distance from one base to another base, but for oblique cylinder, the height is taken as the perpendicular distance from one base to another base, which in the given diagram, is shown as 7

So, for the given cylinder:

Height = 7

Radius = 6

Volume = Base · Height

Volume = πr² · h

Volume = π(6)² · 7

Volume = 252π units³

Answer:

its 25° .

because its an isosceles trangle as jk=kl =7.

and angle J is equal to angle L as they are base angles of an isosceles triangle.

Answer:

Yes

Step-by-step explanation:

Since the height is twice the length of base (b), we can say h= 2b.

Since the area of triangle = base x height /2, we can see if it is possible that the area of sail be 10in².

b(2b) /2 = 10

2b² / 2 = 10

b² = 10

b= √10

b = 3.1623in. or -3.1623in.

Even though b can be -3.1623, but since the length in real life cannot be negative, this answer is not valid. Still, 3.1623in. is possible in real life, so, the area of the sail boat can be 10 in².

Yes, the area of the sail can be 10 square inches.

Area is the amount of area occupied by an object's flat (2-D) surface or shape.

Given:

A hobbyist is making a toy sailboat.

For the triangular sail, she wants the height h (in inches) to be twice the length of the base b (in inches).

Then, height = 2b inches.

That means,

the area of the triangle = 10 square inches.

1/2 x b x 2b = 10

b² = 10

b = √10

Therefore, the area can be 10 square inches.

Answer:

111 girls

Step-by-step explanation:

Given

Boys: Every 17 outdoor ≈ 20 indoor

Girls: 3:2 outdoor to indoor

First, we'll determine the ratio of outdoor to indoor for boys;

Recall that;

17 choose indoor while 20 choose outdoor;

The ratio of outdoor to indoor is;

20 : 17

Convert to fraction:

[tex]\frac{20}{17}[/tex]

Let x represent number of boys that choose indoor when 85 boys chose outdoor;

The ratio of outdoor to indoor is;

x : 85

Convert to fraction

[tex]\frac{x}{85}[/tex]

Equate both fractions

[tex]\frac{20}{17} = \frac{x}{85}[/tex]

Multiply both sides by 85

[tex]85 * \frac{20}{17} = \frac{x}{85} * 85[/tex]

[tex]85 * \frac{20}{17} = x[/tex]

[tex]\frac{1700}{17} = x[/tex]

[tex]100 = x[/tex]

[tex]x = 100[/tex]

This implies that when 85 chose outdoor, 100 chose indoor for boys;

Total = 100 + 85

Total = 185 boys surveyed

Recall that the question says the same number of boys and girls were surveyed

This implies that

Total Girls Surveyed = 185

For the girl ratio;

Outdoor to Indoor= 3:2

Number of girls that chose outdoor is as follows;

[tex]Outdoor = \frac{3}{3 + 2} * Total[/tex]

[tex]Outdoor = \frac{3}{3 + 2} * 185[/tex]

[tex]Outdoor = \frac{3}{5} * 185[/tex]

[tex]Outdoor = \frac{555}{5}[/tex]

[tex]Outdoor = 111[/tex]

Hence, the number of girls that chose outdoor is 111

Answer:

The probability that the team puts the top hip hop dancer in the third position and top break dancer in the first position is 1/72.

Step-by-step explanation:

It is provided that a dance team has 9 dancers to perform different roles in each performance.

The number of arrangements of the 9 dancers in the different roles is:

Number of order of performance = 9!

                                                       = 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

                                                       = 362880

If the team selects the same order as last performance, then the possible number of arrangements is, 1.

The probability that the team selects the same order as last performance is:

[tex]=\frac{1}{362880}[/tex]

Now it is provided that the team puts the top hip hop dancer in the third position and top break dancer in the first position.

So of the 9 positions the 1st and 3rd are occupied.

There are a remaining 7 positions to be filled by 7 dancers.

That can happen in 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040 ways.

Compute the probability that the team puts the top hip hop dancer in the third position and top break dancer in the first position as follows:

[tex]=\frac{5040}{362880}\\\\=\frac{1}{72}[/tex]

Thus, the probability is 1/72.

Answer:

24 units.

Step-by-step explanation:

we can use  concept of Thales intercept theorem in this problem

according to this theorem, if  there are n lines parallel to each then and two transverse line drawn such that they intersect the three parallel line given the problem, then the parallel line divides the transverse line equal proportion.

For this problem

For the line having length 45, one of the length is 25 units,

then other length will be 45-25 = 20 unit

Now using Thales intercept theorem

30/? = 25/20

30/? = 5/4

? = 30*4/5 = 24

Thus, missing side length will be 24 units.

Answer:

Company B

Step-by-step explanation:

We would use z score formula

z = (x - μ) / σ

x = raw score

μ = mean

σ = Standard deviation

let x = 260 with the mean μ1 = 276 and standard deviation σ = 5.8

let x = 260 with the mean μ2 = 252 and standard deviation σ = 3.4

z1 = (x- μ1) / σ = (260- 276) / 5.8 = -2.7586206897

z2 = (x2 - μ) / σ = (260 -252) / 3.4= 2.3529411765

Comparing the two z scores, we can see that company B has the probability of producing 260 nails because it has a positive z score of approximately 2.35 compared to company A with a z score of -2.76.

Answer:

It is important to know that,

The area of any triangle with two given sides and an inclusive angle = 1/2(absinθ)

In the question above, we are given the following values:

Where : a = 8, b = 12, θ = C = 84°

Area of the Triangle ABC = 1/2 ×( 8 × 12 × sin 84)

Area of Triangle ABC = 47.737050978 square units

Approximately to the nearest tenth = 47.7 square units.

Therefore, the Area of triangle ABC to the nearest tenth = 47.7 square units.

The lumberjack cuts 7 numbers of the log on the painted lines.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Let length of the log on the painted lines = 72 units

Pedro wants the log cut into 24 equal parts,

⇒ 72/24 = 3 units

John wants the log cut into 18 equal parts,

⇒ 72/18 = 4 units

Hence, the lumberjack cuts 7 numbers of the log on the painted lines.
