Answer: Obtuse Triangle

Step-by-step explanation:

It is not right, because a^2 + b^2 doesn’t equal c^2. It is Actually obtuse because a^2 + b^2 is greater than c^2 because 20^2+50^2 =2900 which is greater than 2601 or 51^2.

Answer:

3

Step-by-step explanation:

Your teacher is correct. The reason is because it is the total cost of both the chocolate and the can… if the choc is $3 and can is $1, you can have 3 chocolate bars because when you add the one can which is one dollar, it equals $10

3x3 = 9

9+1 = 10

Therefore 3 is the answer

Answer:

overestimate

Step-by-step explanation:

The actual numbers are 4.5 and 11.91.

She used 5, which is greater than 4.5 and 12 which is grater than 11.91, so her estimate is an overestimate.

The probability that the claim of James is correct is 1%.

The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, is its standard error. The standard error of the mean is the term used when the statistic is the sample mean.

In order to know if the claim of James is correct or not, firstly we need to determine the standard error. The standard error is the ratio of the standard deviation and the square root of the sample. Therefore, the standard error can be written as,

[tex]\rm Standard\ Error, SE =\dfrac{\sigma}{\sqrt n} = \dfrac{0.4}{\sqrt5} =0.178[/tex]

Thus, the standard error is 0.178.

Further, The z-score is defined as the distance from the sample to the population mean in units of standard error. Therefore, the z-score can be written as,

[tex]z = \dfrac{X-\mu}{SE}=\dfrac{(3- 2.5)}{0.178} = 2.81[/tex]

Using the Z-table in order to know the probability of the claim of James is correct or not, therefore, at this z-score, the probability is 0.9974≈1.00%.

Hence, the probability that the claim of James is correct is 1%.

Taking LCM both sides ;

[tex]{:\implies \quad \sf \dfrac{35x+70-(51-9x)}{15}=\dfrac{18x-(4x+2)-15}{3}}[/tex]

Given: {(7x + 14)/3} - {(17 - 3x)/5} = 6x - {(4x + 2)/3} - 5

Asked: Find the value of x = ?

Explanation: Given equation is {(7x + 14)/3} - {(17 - 3x)/5} = 6x - {(4x + 2)/3} - 5

⇛{(7x + 14)/3} - {(17 - 3x)/5} = {(6x)/1} - {(4x + 2)/3} - (5/1)

⇛{(7x*5 + 14*5 - 17*3 + 3x*3)/15} = {(6x*3 - 4x*1 - 2*1 - 5*3)/3}

⇛{(35x + 70 - 51 + 9x)/15} = {(18x - 4x - 2 - 15)/3}

⇛{(35x + 9x + 70 - 51)/15} = {(18x - 4x - 2 - 15)/3}

⇛{(44x + 19)/15} = {(14x - 17)/3}

⇛[{1/15}(44x + 19)] = [{1/3}(14x - 17)}]

⇛{(44x + 19)/15} = {(14x - 17)/3}

Since (a/b) = (c/d) ⇛a(d) = b(c) ⇛ad = bc

Where, a = 44x + 19, b = 15

c = 14x - 17 and d = 3

On applying cross multiplication then

⇛3(44x + 19) = 15(14x - 17)

Multiply the numbers outside of the bracket with numbers in the bracket.

⇛132x + 57 = 210x - 255

Shift the variable value on LHS and constant value on RHS.

⇛132x - 210x = -255 - 57

Subtract the values on LHS and RHS.

⇛(-78x) = (-312)

Shift the number (-78) from LHS to RHS.

⇛x = {(-312)/(-78)

Simplify the RHS fraction to get the final value of x.

⇛x = 4/1

Therefore, x = 4

Answer: Hence, the value of x for the given problem is 4.

Verification:

Check whether the value of x for the given problem is true or false.

If x = 4 then LHS of the equation is

{(7x + 14)/3} - {(17 - 3x)/5}

= [{7(4) + 14}/3] - [{17 - 3(4)}/5]

= {(7*4 + 14)/3} - {(17 - 3*4)/5}

= {(28 + 14))3} - {(17 - 12)/5}

= (42/3) - (5/5)

= (42/3) - 1

= (42/3) - (1/1)

= {(42 - 1*3)/3

= {(42 - 3)/3}

= (39/3)

= 13/1

= 13

And RHS = 6x - {(4x + 2)/3} - 5

= 6(4) - [{4(4) + 2}/3] - 5

= 24 - {(16 + 2)/3} - 5

= 24 - (18/3) - 5

= 24 - (6/1) - 5

= (24/1) - (6/1) - (5/1)

= (24*1 - 6*1 - 5*1)/1

= (24 - 6 - 5)/1

= (24 -11)/1

= 13/1

= 13

On comparing with both the sides, we notice that LHS = RHS is true for x = 4

Hence, verified.

The total value of coins to create a silver mile following the specific rules stated is $38,114.18

63360 - 31650.48 = 31679.52 inches

A third of the distance is missing: 10559.84 inches

This means 10,559.84 inches/ 1.205 in = 8763.35 rounded to 8764

Total distance coverd 8,764 x 1.205 in = 10560.61

Total distance left: 31679.52 - 10560.61 = 21118,91 / 4 = 5279.72

This means 5279.72 / 0.750 =7039.62 rounded to 7040

7040 x 0.750 = 5280

Total distance left = 21118,91 -  5280 = 15,838.91 / 5 = 3167.782

This means 3167.82 / 0.705 = 4493.36 rounded to 4494

0.705 x 4494 = 3168.27

Total distance left = 15,838.91 - 3168.27 = 12670.64

Let's do

[tex]\\ \rm\Rrightarrow x+iy[/tex]

[tex]\\ \rm\Rrightarrow 0+0i[/tex]

Answer:

8

Step-by-step explanation:

Integers are whole numbers or opposite of whole numbers.

The slope is 111/11.

How?

Change of y is 1000-1=999.

Change of x is 100-1=99.

The slope is 999/99=111/11.

So if we start at (1,1) and we rise 111 and run 11 right, we get (12,112).

*Rise effects y and run effects x.

If we do that again from (12,112) we get (23,223).

Following the pattern of going up 111 and right 11 from each new location discovered we get all the of these points:

Start (1,1)

(12,112)

(23,223)

(34,334)

(45,445)

(56,556)

(67, 667)

(78, 778)

(89, 889)

(100, 1000) which is the end.

So we just need to count tthe points between begin point and end point which is 8 points.

Step-by-step explanation:

There are two "special" right triangles that show up in trig and geometry problems.

The isosceles right triangle has angles of 45°-45°-90°, and side length ratios 1 : 1 : √2.

The half-equilateral triangle has angles of 30°-60°-90°, and side length ratios 1 : √3 : 2.

You will do yourself a favor if you remember and learn to recognize these triangles.

The hypotenuse of the isosceles right triangle is 14√2. This tells you the basic ratio has been multiplied by 14. The side length is ...

The half-equilateral triangle has middle-length side 12√3. This means the basic ratio has been multiplied by 12. The triangle short side is 12, and the long side is twice that:

A ✓5 is the irrational number.

Step-by-step explanation:

Have a good day. :)

Hello.

A rational number can be expressed as a fraction.

Let's check if we can express the given numbers as fractions.

The first number is √5.

Can we express √5 as a fraction? No.

Why? Because √5=2.236...

We cannot express this number as a fraction.

Thus, √5 is irrational.

Let's check the other 3 numbers.

The second number is -2.

Can we express -2 as a fraction? Sure!

[tex]\displaystyle-\frac{2}{1}[/tex]

Thus, -2 is rational.

What about the third number?

Well, it's already a fraction.

Seems like Option A is the right option, huh? Well, let's check the last one as well.

The last one is √9.

9 does have a square root, unlike 5.

It equals 3:

√9=3

Let's express 3 as a fraction:

[tex]\displaystyle\frac{3}{1}[/tex]

Therefore, Option A is the right option ;)

The evaluation of the figures needed for the considered survey are:

Suppose the data specified is of n sized as [tex]x_1, x_2, \cdots , x_n[/tex]

Let this data's mean be [tex]\bar{x}[/tex]

Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.

It is calculated as:

[tex]M.A.D = \dfrac{\sum_{i=1}^n|x_i-\bar{x}|}{n}[/tex]

The data is missing from the problem statement, and is as shown below:

Calculating the needed figures part by part:
Part 1: Mean of the group that studied, rounded to the nearest tenth.

Mean is the sum of observations divided by number of observations.

The sum of 18 observations:   88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84

is 1667. Thus, its mean is 1667/18 ≈ 92.61 ≈ [tex]\bar{x}[/tex]

Part 2: The mean absolute deviation of the group that studied:

The absolute deviations of 18 observations:  88, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 84

from the mean  [tex]\bar{x}[/tex] ≈ 92.61 are approx:

[tex]|92.61 - 88| = 4.6\\|92.61 - 100| = 7.4\\|92.61 - 94| = 1.4\\|92.61 - 79| = 13.6\\|92.61 - 92| = 0.6\\|92.61 - 100| = 7.4\\|92.61 - 95| = 2.4\\|92.61 - 83| = 9.6\\|92.61 - 89| = 3.6\\|92.61 - 99| = 6.4\\|92.61 - 100| = 7.4\\|92.61 - 91| = 1.6\\|92.61 - 89| = 3.6\\|92.61 - 95| = 2.4\\|92.61 - 100| = 7.4\\|92.61 - 93| = 0.4\\|92.61 - 96| = 3.4\\|92.61 - 84| = 8.6\\[/tex]

Their sum is 91.8 approx.

Thus, the mean of these 18 absolute deviations comes out as

[tex]91.8/18 \approx 5.1[/tex]

Part 3: The number of scores which are within one mean absolute deviation of the mean

The range within one absolute deviation of the mean is [tex][92.61 - m.a.d, 92.61 + m.a.d] = [92.61 - 5.1, 92.61 + 5.1] = [87.51, 97.71][/tex]

The values from the studied group which is in this range are:

88, 94, 92, 95, 89, 91, 89, 95, 93, 96

They are total 10 in counts.

Thus, the number of scores which are within one mean absolute deviation of the mean is 10

Thus, the evaluation of the figures needed for the considered survey are:
