Answer:

The standard deviation = 1.9

Step-by-step explanation:

standard deviation, ρ = sqrt ( [tex]\frac{sum(x_{i} - u)^{2} }{N}[/tex])

Where u is the mean of the data, [tex]x_{i}[/tex] each given value, and N is the number of data given.

Mean, u = [tex]\frac{6+5+2+5+8}{5}[/tex]

              = 5.2

So that;

[tex](6-5.2)^{2}[/tex]  = [tex](0.8)^{2}[/tex] = 0.64

[tex](5-5.2)^{2}[/tex] = [tex](-0.2)^{2}[/tex] = 0.04

[tex](2-5.2)^{2}[/tex]  = [tex](-3.2)^{2}[/tex] = 10.24

[tex](5-5.2)^{2}[/tex] = [tex](-0.2)^{2}[/tex] = 0.04

[tex](8-5.2)^{2}[/tex] = [tex](2.8)^{2}[/tex] = 7.84

Sum = 18.8

So that;

[tex]\sqrt{\frac{18.8}{5} }[/tex]  = [tex]\sqrt{3.76}[/tex]

          = 1.9391

          = 1.9

The standard deviation of the given data is 1.9

Answer:

obtuse triangle

Step-by-step explanation:

Answer:

It is a obtuse scalene triangle.

Step-by-step explanation:

Equilateral: all three sides are equal

Isosceles: two sides are equal

Scalene: no sides are equal to each other

If a squared + b squared = c squared it is a right triangle

If a squared + b squared is less than c squared it is a obtuse triangle.

If a squared + b squared is more than c squared it is a acute triangle.

Answer:

$127.03

Step-by-step explanation:

A snow cone machine price at $139 is on after for 20 off.

The price after discount=139-20=$199

The sale tax rate 6.75%

Price with sales tax=199+(6.75%×199)

=199+(0.0675×199)

= 199+8.03

=$127.03

Step-by-step explanation:

16% of 576

=16/100 x 576

=2304/25

=92 4/25

Answer: 25

Step-by-step explanation:

6 x 2 = 12

8 + 4 = 12

therefore, (2 x 6) + (8 + 4) + 1 = 12 + 12 + 1

which gives 25

Given:

You bought [tex]\dfrac{3}{4}[/tex] pound of fudge for 6.75.

To find:

The equation and solve the equation to find the cost of the fudge per pound.

Solution:

Let x be the cost of the fudge per pound.

You bought [tex]\dfrac{3}{4}[/tex] pound of fudge for 6.75.

[tex]\dfrac{3}{4}x=6.75[/tex]

[tex]3x=6.75\times 4[/tex]

[tex]3x=27[/tex]

Divide both sides by 3.

[tex]x=\dfrac{27}{3}[/tex]

[tex]x=9[/tex]

Therefore, the required equation is [tex]\dfrac{3}{4}x=6.75[/tex] and the cost of the fudge is 9 per pound.

Answer:

If 68% is 17 then 100 percent is 25 I think

Step-by-step explanation:

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

68% = 17

100% = 25

The percent proportion for the bar diagrams are:

17and 25.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

There are two bar diagrams.

Blue bar diagram:

68% = 17

Red bar diagram:

68% = 17

Multiply both sides by 100/68.

100% = 100/68 x 17

100% = 25

Thus,

68% = 17

100% = 25

The percent proportion for the bar diagrams are:

17and 25.

Answer:

See answer below

Step-by-step explanation:

In this case, we can assume that this function follows a linear function. In this case, the general expression would be:

y = a + bx

Where:

a: Y intercept

b: slope of the function

To get the slope we need to apply the following expression:

b = y₂ - y₁ / x₂ - x₁

We already have two points, (80,0) and (40,16) from here, we can determine the slope:

b = 16 - 0 / 40 - 80

b = -16/40

b = -2/5

Now that we know the slope, we can determine the y-intercept if it have:

a = y - bx

Using any point, we can calculate it:

a = 0 - (-2/5*80)

a = 0 + 160/5

a = 32

With these two values, we can write the function:

(x-11)(7x-2)=0

x=11 or x=2/7

Answer:

x = [tex]\frac{2}{7}[/tex], x = 11

Step-by-step explanation:

Given

7x(x - 11) - 2(x - 11) = 0 ← factor out (x - 11) from each term

(x - 11)(7x - 2) = 0

Equate each factor to zero and solve for x

x - 11 = 0 ⇒ x = 11

7x - 2 = 0 ⇒ 7x = 2 ⇒ x = [tex]\frac{2}{7}[/tex]
