Queremos encontrar el número total de árboles en un jardín botánico siendo que conocemos el porcentaje de un dado tipo de arbol, y cuantos de estos arboles tenemos.

Veremos que el número total de arboles es 250.

-------------------------------------------------

Para resolver esto, primero debemos analizar la información que se nos da:

Si definimos N como el número total de arboles, sabemos que el 18% de N es igual que 45.

Entonces podemos escribir:

(18%/100%)*N = 45

0.18*N = 45

Ahora podemos resolver esto para N:

N = 45/0.18 = 250

Es decir, hay 250 árboles en total.

5x=2x+27

3x=27

X=9

Answer: A.  9

Step-by-step explanation:

The diagonal is bisected by the other diagonal.  So the 2 parts of the diagonal are equal

5x - 3 =  2x + 24                 >Bring like terms to 1 side

3x = 27                                >Divide both sides by 3

We have a total of seven 4-tuples that satisfy the given relation.The given relation is {(a,b,c,d) | a,b,c,d∈!+ , a+b+c+d = 6}. It can be understood as the set of 4-tuples (a, b, c, d) such that a, b, c, and d are positive integers and their sum is equal to 6.

Let's now list all the possible 4-tuples that satisfy the given relation. The possible combinations are as follows: (1, 1, 1, 3), (1, 1, 2, 2), (1, 2, 1, 2), (2, 1, 1, 2), (1, 2, 2, 1), (2, 1, 2, 1), and (2, 2, 1, 1).

Here's a brief explanation on how these 4-tuples were obtained. Let a, b, c, and d be positive integers such that a+b+c+d = 6. The least possible value that each variable can take is 1.

So, we start with a=1 and find all possible values of (b, c, d) that satisfy the given equation. Then, we move to a=2 and repeat the process. Finally, we list all the possible 4-tuples that we obtained.

Thus, we have a total of seven 4-tuples that satisfy the given relation.

Answer:5 35/36

Step-by-step explanation:

63 13/18 − 57 3/4 =?

Solving the whole number parts

63−57=6

Solving the fraction parts

13/18−3/4 is equal to 26/36 − 27/36

Combining the whole and fraction parts

6−1/36 = 5 35/36

cos(tan^(-1)(-2/3)) simplifies to 3√13 / 13.

To evaluate the expression cos(tan^(-1)(-2/3)), we can use the trigonometric identity:

cos(tan^(-1)(x)) = 1 / √(1 + x^2)

In this case, x is -2/3. Substituting the value into the identity:

cos(tan^(-1)(-2/3)) = 1 / √(1 + (-2/3)^2)

Now, let's calculate the value:

cos(tan^(-1)(-2/3)) = 1 / √(1 + 4/9)

                   = 1 / √(13/9)

                   = 1 / (√13/3)

                   = 3 / √13

                   = 3√13 / 13

Step-by-step explanation:

Answer: answer is -4 5/12

Step-by-step explanation:

Answer:

-4  - 5/12, or option 3.

Step-by-step explanation:

Change the denominator of each fraction to a common denominator. In this situation, the common denominator between the three fractions is 12.

- 7  2/3 = - 7  8/12

- 5  1/2 = - 5  6/12

8  3/4 = 8  9/12

Add them together.

-7  8/12 - 5  6/12 + 8  9/12 =

First, add the whole numbers together.

-7 - 5 + 8 - 8/12 - 6/12 + 9/12 =

-12 + 8 - 8/12 - 6/12 + 9/12 =

-4 - 8/12 - 6/12 + 9/12 =

Now, add the numerators of the fractions together.

-4 + (-8 -6 + 9)/12

-4 + (-5)/12 =

-4  - 5/12

The answer is -4  - 5/12, or option 3.

Answer:

x=1

Step-by-step explanation:

if you do 1x5=5 1x0=0 so yur left with 5^0=1

Answer: i think x=1

Step-by-step explanation: 5^0=1 (1)^x=1 x=1

Solve  :    x-1 = 0  

Add  1  to both sides of the equation :  

                     x = 1

The given differential equation is separable:

\(\displaystyle \frac{dy}{dx} = \frac{2\sqrt y}x \implies \frac1{\sqrt y} \, dy = \frac2x \, dx\)

Integrate both sides:

\(\displaystyle \int y^{-1/2} \, dy = \int \frac2x \, dx\)

\(2y^{1/2} = 2\ln|x| + C\)

\(2\sqrt y = 2 \ln|x| + C\)

Given that y(-1) = 4, we find

\(2\sqrt4 = 2\ln|-1| + C \implies C = 4 - 2\ln(1) = 4\)

Then

\(2\sqrt y = 2 \ln|x| + 4\)

Solve for y :

\(\sqrt y = \ln|x| + 2\)

\(\left(\sqrt y\right)^2 = \left(\ln|x| + 2\right)^2\)

\(\boxed{y = \left(\ln|x| + 2\right)^2}\)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let x be the random variable representing the miles per gallon of Chevrolet Cobalt in highway driving. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

From the information given,

µ = 33

σ = 4

a) the probability that a randomly selected Cobalt gets more than 34 miles per gallon is expressed as

P(x > 34) = 1 - P(x ≤ 34)

For x = 34,

z = (34 - 33)/4 = 0.25

Looking at the normal distribution table, the probability corresponding to the z score is 0.5987

P(x > 34) = 1 - 0.5987

P(x > 34) = 0.4013

b) since sample size is given, the formula would be

z = (x - µ)/(σ/n)

n = 16

z = (34 - 33)/(4/√16)= 1

Looking at the normal distribution table, the probability corresponding to the z score is 0.8413

P(x > 34) = 1 - 0.8413

P(x > 34) = 0.1587

c) Since the population is normally distributed, then, the sample is also normally distributed. The correct option is

Yes, we could, because the distribution of the sample mean is always normal regardless of the sample size

Answer:

• 25%

• Drama movie

Step-by-step explanation:

• Total number of children

= 16 +12 +18 +20 +14

= 80

Percentage of children that voted for action movie

\( = \frac{no. \: of \: children \: that \: voted \: for \: action \: movie}{total \: number \: of \: children} \times 100\%\)

\( = \frac{20}{80} \times 100\%\)

\( =\textbf{25\%}\)

• Total number of votes

= 30 +32 +36 +36 +26

Since Drama movie received 32 votes, it received 20% of the total votes.

8.5 bags will actually be needed if B=x(2x+7)+3(2x+7)+(x+4)(2x+7), where the quantity (2x + 7) equals 4

Expression: An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.) Expressions can be thought of as similar to phrases. In language, a phrase on its own may include an action, but it doesn't make a complete sentence.

Number of bags needed B=x(2x+7)+3(2x+7)+(x+4)

where the quantity (2x+7)=4

2x+7=4

2x=4-7

2x=-3

x=-3/2

now we are given the no. of bags needed

B=x(2x+7)+3(2x+7)+(x+4)

substitute the value of x which is found above x=-3/2

B=(-3/2)(2(-3/2)+7)+3(2(-3/2)+7)+((-3/2)+4)

B=8.5

hence 8.5 bags are needed
