Answer:

butterflies (b)=50

butterflies in 6 months =20/100×50=10+b =60

butterflies in 12 months =2(6months)

butterflies in 12 months= 120

The population of butterflies after 1 year is 72 butterflies

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the present population of butterflies be A = 50 butterflies

The percentage increase after 6 months = 20 %

The population of butterflies after 6 months = present population of butterflies + percentage increase after 6 months

The population of butterflies after 6 months = 50 + ( 20/100 ) x 50

                                                                         = 50 + ( 0.2 x 50 )

                                                                         = 50 + 10

                                                                         = 60 butterflies

The population after 6 more months =  population of butterflies after 6 months + percentage increase after 6 months

The population after 6 more months =  60 + ( 20/100 ) x 60

                                                              = 60 + 0.2 x 60

                                                              = 60 + 12

                                                              = 72 butterflies

Hence , The population of butterflies after 1 year is 72 butterflies

Answer:

9

Step-by-step explanation:

6 divided by 2/3 = 9

Answer:

To find the z-score, we use the formula:

z = (x - mu) / (sigma / sqrt(n))

where:

x = sample mean = $5100

mu = population mean = $5000

sigma = population standard deviation = $250

n = sample size = 64

Substituting the values, we get:

z = (5100 - 5000) / (250 / sqrt(64))

z = 2.56

Therefore, the z-score that corresponds to a sample average of $5100 is 2.56 (rounded to four decimals).

Step-by-step explanation:

8 + x - 8 = 13 + 2x - 8

The 8 cancels on the left

x - 2x = 13 + 2x - 8 - 2x

The 2x cancels on the right

x - 2x = 13 - 8

Do the calculation to find

- x = 5

- x . (-1) = 5 . (-1)

Times by -1 to cancel the negative sign because you arises to find x and not -x

You finally get x = -5

The value of angle x in the triangle is 15°

Given: the triangle ABC with equal sides of 9 units.

Since the triangle has equal sides, it will also have equal angles (i.e. it is an equilateral triangle).

Thus, <A = <B = < C =  4x°

Since the sum of angles in a triangle is 180°. We have:

<A + <B + < C = 180°

4x + 4x + 4x = 180°

12x = 180

x = 180/12

x = 15°

Therefore, the value of x is 15°

The length of arc is 16.049 unit.

An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference. A curve contains an arc.

We have,

m <STU = 46

and ST = 20 units

So, length of Arc

= 46/ 360 2πr

= 46/360 x 2 (3.14)(20)

= 16.0488 unit

Thus, the length of Arc is 16.0488 unit.

Step-by-step explanation:

The x and y-intercepts of the rational function are; (-3, 0) and (0, -3/25).

The vertical asymptotes of the function are; x = ± 5.

The horizontal asymptotes of the function is f(x) = 0.

For x-intercept; let f (x) = 0;

0 = (x + 3) / (x² - 25)

x + 3 = 0; x = -3 or (-3, 0).

For the y-intercept; let x = 0.

f (0) = (0 + 3) / (0² - 25)

= -3/25 or (0, -3/25).

For the vertical asymptotes;

x² - 25 = 0

x² = 25

x = ±5.

For the horizontal asymptote;

Since the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is; f (x) = 0.

Answer:

The central angle measure of the sector in radians is \(\theta=\frac{13}{9}\).

Step-by-step explanation:

A sector of a circle is the portion of a circle enclosed by two radii and an arc. It resembles a "pizza" slice.

The area of a sector when the central angle is in radians is given by

                                                    \(A=(\frac{\theta}{2})\cdot r^2\)

where

r = radius

θ = central angle in radians

We know that the area of the sector is \(26 \:cm^2\) and the radius is 6 cm. Applying the above formula and solving for the central angle (\(\theta\)) we get that

                                                   \(26=(\frac{\theta}{2})\cdot (6)^2\\\\\left(\frac{\theta}{2}\right)\left(6\right)^2=26\\\\\frac{\frac{\theta}{2}\cdot \:6^2}{36}=\frac{26}{36}\\\\\frac{\theta}{2}=\frac{13}{18}\\\\\theta=\frac{13}{9}\)

The two types of frequency distributions are;

When the data consists of discrete, separate values, this sort of distribution is used. It displays the frequency or number of occurrences of each value.

The data is often expressed in a table with two columns: one for distinct values and another for the frequencies of those values.

This distribution is utilized when the data is continuous and has a wide range of values. It entails categorizing the data into intervals or classes and then calculating the frequency of values that fall within each interval.
