Answer:

Radio es 8.799974535 cm

Diametro es 17.59994907 cm

Explicación paso a paso:

Como tienes la medida en cm, me indica que es el perimetro del circulo

C=πd

55.292=3.1416 d

\frac{55.292}{3.1416} =d

3.1416

55.292

=d

17.59994907=d

Para sacar radio hay que dividir entre 2

r=8.799974535

Answer:

The appropriate solution is "95%".

Step-by-step explanation:

The given values are:

Lower bound,

= 173.8

Upper bound,

= 196.2

Mean of cholesterol,

= 138 milligrams

S = 17.6 mg

Now,

The margin of error (E) will be:

=  [tex]\frac{Upper \ bound-Lower \ bound}{2}[/tex]

=  [tex]\frac{196.2-173.8}{2}[/tex]

=  [tex]\frac{22.4}{2}[/tex]

=  [tex]11.2[/tex]

As we know,

⇒  [tex]E=t_{\alpha 12}\times \frac{S}{\sqrt{n} }[/tex]

On putting the values, we get

⇒   [tex]11.2=t_{\alpha 12}\times \frac{17.6}{\sqrt{12} }[/tex]

On applying cross-multiplication, we get

⇒   [tex]t_{\alpha 12}=2.2044[/tex]

∴ [tex]\frac{\alpha}{2} =0.025[/tex]

   [tex]\alpha = 0.025\times 2[/tex]

      [tex]=0.05[/tex]

hence,

The confidence level will be:

⇒  [tex]CI=1-\alpha[/tex]

⇒        [tex]=1-0.05[/tex]

⇒        [tex]=0.95[/tex]

⇒        [tex]=95[/tex]%

Answer:

h = 5(tane)

Step-by-step explanation:

The diagrammatic representation of the question given is attached below ;

The height of the light pole, h = opposite side

Adjacent side = 5 feets

Angle of elevation = e

Using trigonometry ;

Tan e = opposite / Adjacent

Tan e = h / 5

Making h the subject ;

h = 5(tane)

Answer:

A. 30 = ⅓(8h)

Step-by-step explanation:

Volume of cone (V) = 30 ft³ (given)

Base area (BA) = 8 ft² (given)

height = ?

Formula for volume of a cone = ⅓*B.A*h

Plug in the values into the equation

30 = ⅓*8*h

30 = ⅓(8h)

Expression to find the height will be 30 = ⅓(8h)

Answer:

6.14 minutes   or   6 minutes & 8.4 seconds

Step-by-step explanation:

Initial elevation: 453 ft

Final elevation: 146 ft

Difference in elevation: 453 ft - 146 ft = 307 ft

speed = 50 ft/min

speed = distance/time

time * speed = distance

time = distance/speed

time = (307 ft)/(50 ft/min)

time = 6.14 minutes = 6 minutes + 0.14 * 60 seconds

time = 6.14 minutes = 6 minutes + 8.4 seconds

Answer:

3/10

Step-by-step explanation:

Remark

The denominator of the probability is the entire amount present. Just add

Denominator

Blue/Large      17

Red/Large        8

Small                3

Red Small      12

Total               40

Red / Small

P(red/small) = 12 / 40

P(red/Small)  = 3 / 10

Answer:

c) [tex]\frac{x-2}{x+6}[/tex]

Step-by-step explanation:

When given that function (f) is the following,

[tex]f(x)=\frac{x+2}{x^2+4x-12}[/tex]

The wisest move to first make is to factor the expression, factoring is the process by which one rewrites a quadratic expression as the product of two linear expressions,

[tex]f(x)=\frac{x+12}{(x+6)(x-2)}[/tex]

If is given that function (g) is the following,

[tex]g(x)=\frac{4x^2-16x+16}{4x+48}[/tex]

Then one should also factor the expression,

[tex]g(x)=\frac{4(x-2)^2}{4(x+12)}[/tex]

One is asked to find the following,

[tex]f(x)*g(x)[/tex]

To do this operation, one must multiply the two functions together. It is easiest to do so when the functions are in factored form,

[tex]f(x)*g(x)[/tex]

Substitute,

[tex](\frac{x+12}{(x+6)(x-2)})(\frac{4(x-2)^2}{4(x+12)})[/tex]

Simplify, cross out like terms in the numerator and denominator,

[tex]\frac{x-2}{x+6}[/tex]

Answer:

d

Step-by-step explanation:

d is .04 percent plz mark branliest

Answer:

5) P (arrive) + P (not arrive) = 100%   Complements

80% + P( not arrive) = 100%    Substitute thr ralees

P ( not arraive) = 100% - 80%   Isolate the needed

P ( not arrive) = 20%

therefor, the probability of not arriving on time is:-

20%, or 0.20, or 1/5

The complements of arriving on time is not arriving on time.

The probability is equal to 100%

Answer:

The expression ( Unsolved equation ) would be 12 + 6 = X .

The answer would be X = 18 .

Please give me Brainliest ! :)

Answer:

C. x = 3, y = -6 is the answer.

Step-by-step explanation:

1. Isolate x for x = 2y = 15 -> x = 15 + 2y

2. Substitute x = 15 + 2y -> [2 (15 + 2y) + 4y = -18]

3. Simplify -> [30 + 8y = -18)

4. Isolate y for 30 + 8y = -18 -> y = -6

5. For x = 15 + 2y, substitute y = -6 -> x = 15 + 2(-6)

So, x = 3 and y = -6 are the solutions to this system of equations.

Hope this helps! :)

Answer:

[tex]180\:\text{calories}[/tex]

Step-by-step explanation:

The question implies a constant rate or distribution of calories. Therefore, we can set up the following proportion:

[tex]\frac{14}{126}=\frac{20}{x},\\14x=20\cdot 126,\\14x=2520,\\x=\boxed{180\:\text{calories}}[/tex]

Anwner : 4/52

Explanation : The chance of drawing one of the four aces from a standard deck of 52 cards is 4/52; but the chance of drawing a second ace is only 3/51, because after we drew the first ace, there were only three aces among the remaining 51 cards. Thus, the chance of drawing an ace on each of two draws is 4/52 × 3/51, or 1/221.
