The geometric mean of a number and nine times the number is 30. What is the number?

The value of m is 36 degrees and the value of n is 27 degrees

Consider the triangle on right side

Two sides of the triangle is equal, therefore it is an isosceles triangle.

One angle of the triangle = 126 degrees

Other two angles of the triangle is equal

The sum of interior angles of the triangle is 180 degrees

Then, the equation will be

126 + n + n = 180

2n + 126 = 180

2n = 180 - 126

2n = 54

n = 54/2

n = 27 degrees

Consider the full triangle

The equation will be

(m +27) + 90 +27 = 180

m + 27 + 90 + 27 = 180

m + 144 = 180

m = 180 - 144

m = 36  degrees

Hence, the value of m is 36 degrees and the value of n is 27 degrees

In order to find the sum to the indicated accuracy we need to add

5 terms  as the series is said to be convergent.

Given Series is Σ(-1/3)^n / n where error is less than 0.0005

      = Σ (-1)^n / n3^n

For this series, we will use ratio test

if [tex]\lim_{n \to \infty} |an + 1 / an |[/tex] = L < 1 then series in convergent,

Let an = (-1)^n / n3^n ,  an+1 = (-1)^n+1 / (n+1)3^n+1

[tex]\lim_{n \to \infty} |an + 1 / an |[/tex]   =  [tex]\lim_{n \to \infty} | ((-1)^n+1 / (n+1)3^n+1)(n3^n/(-1)^n) |[/tex]

By solving we get,

[tex]\lim_{n \to \infty} |an + 1 / an |[/tex] = 1/3 < 1

Then given series is convergent.

By alternating series estimation theorem we have,

|Rn|=|S-Sn| <= an+1

an+1 <= 0.0005

1 / (n+1)3^n+1 <= 0.0005

(n+1)3^n+1 >= 2000

2 * [tex]3^{2}[/tex] >[tex]\neq[/tex] 2000 (n=1)

4 * [tex]3^{4}[/tex] >[tex]\neq[/tex] 2000 (n=3)

Step-by-step explanation:

Answer:plot the point (2,5)

Step-by-step explanation:

The null and alternative hypothesis of the pctrush are explained below.

Given that;

By performing a partial F-test;

In hypothesis testing, the F test is a statistical test that is used to determine whether or not the variances of two populations or two samples are equal. The data in a f test follows a f distribution. In this test, two variances are divided and compared using the f statistic. Depending on the problem's characteristics, a f test can be either one- or two-tailed.

The one-way ANOVA (analysis of variance) test is run using the f value discovered after running the f test. More information on a f test, the f statistic, its critical value, formula, and how to perform a f test for hypothesis testing will be provided in this article.

The f test statistic is used in a test called the f test to determine if the variances of two samples (or populations) are equal. An f test needs a f distribution in the population and independent events for the samples in order to be valid. The null hypothesis can be rejected after conducting the hypothesis test if the f test results are statistically significant; otherwise, it cannot be rejected.

Null hypothesis:

The idea that there is no influence on the population is known as the null hypothesis.

We can reject the null hypothesis if the sample contains sufficient data to refute the assertion that there is no effect in the population (p). If not, we are unable to rule out the null hypothesis.

Although it may sound odd, statisticians only accept the phrase "fail to reject." Avoid using words like "prove" or "accept" when referring to the null hypothesis.

Alternative hypothesis:

The alternate response to your research question is the alternative hypothesis (Ha). It asserts that the populace is affected.

Your research hypothesis and your alternate hypothesis are frequently identical. It is, in other words, the assertion that you anticipate, or hope will be accurate.

The complement of the null hypothesis is the alternative hypothesis. The exhaustive nature of null and alternative hypotheses ensures that they account for all potential outcomes. Additionally, they are mutually exclusive, so only one of them can be true at once.

The equivalent fractions for 8/9 and 5/8 using the least common denominator are 8/9 = 64/72 and 5/8 = 45/72.

What is the Least Common Denominator?

The smallest number that can serve as a common denominator for a group of fractions is known as the least common denominator (LCD). The smallest number that may be used as the denominator to produce a group of comparable fractions that all have the same denominator is known as the lowest common denominator.

The given fractions are 8/9 and 5/8.

The denominators of these fractions are 8 and 9.

so Least Common Divisor(LCD) of 8 and 9 will be = 8 × 9

                                                                                   = 72.

so the equivalent fraction can be calculated as

for 8/9 = [tex]\frac{8*8}{9*8}[/tex]

           = 64/72

and for 5/8 = [tex]\frac{5*9}{8*9}[/tex]

Answer:

Step-by-step explanation:

3b(2x - z^3)  = 2h - 7gx      Distribute 3b

6bx - 3bz^3 = 2h - 7gx      Add 3bz^3 to both sides

6bx = 3bz^3 + 2h - 7gx    Add 7gx to both sides

6bx + 7gx = 3bz^3 + 2h     Factor left side, factor out a gcf of x

x(6b + 7g) = 3bz^3 + 2h     Divide both sides by (6b + 7g) to isolate x

x = (3bz^3 + 2h)/ (6b + 7g)

The choice which describes a sequence of transformations in which the blue figure is the image of the red figure is: 4. Rotate the triangle 90º clockwise about the origin and then translate it 1 unit left and 7 units down.

In Mathematics, the rotation of a geometric figure 90° about the origin in a clockwise or counterclockwise direction would produce a geometric figure that has these coordinates (y, -x).

From the information provided in the graph about the transformation applied to the red triangle to create the blue triangle, we have the following ordered pairs that represents a rotation of 90º clockwise:

(x, y)                                    →              (y, -x)

Ordered pair A = (-5, 2)            Ordered pair A' = (2, 5)

Ordered pair B = (-5, 6)             Ordered pair B' = (6, 5)

Ordered pair C = (-1, 2)             Ordered pair C' = (2, 1)

After a translation of 1 unit left and 7 units down, we have:

Ordered pair A' = (2, 5)       →     Ordered pair A' = (2 - 1, 5 - 7) = (-1, -2)

Ordered pair B' = (6, 5)       →     Ordered pair B' = (6 - 1, 5 - 7) = (.5, -2)

Ordered pair C' = (2, 1)        →     Ordered pair C' = (2 - 1, 1 - 7) = (-1, -6)

Answer:

Step-by-step explanation:

You want a 2-digit number that is 3 times the sum of its digits, where the units digit is 5 more than the tens digit.

Let t represent the tens digit. Then the units digit is (t+5) and the sum of digits is ...

  t +(t +5) = 2t+5

The value of the number is ...

  10t +(t+5) = 11t +5

The value is 3 times the sum of digits, so we have ...

  11t +5 = 3(2t +5)

  11t +5 = 6t +15

  5t = 10 . . . . . . . . . . subtract (6t+5)

  t = 2

  (t+5) = 7

the ant will take 8 days to consume 2 apples.

Given, an ant takes 2 days to consume 1/2 of an apple.

We have to find the number of days ant will take to consume 2 apples.

So, ant takes 2 days = consumption of 1/2 apple

ant takes 4 days = consumption of 1 apple

Consumption of 1 apple = ant takes 4 days

Consumption of 2 apples = ant takes 4×2 days

Consumption of 2 apples = ant takes 8 days

g(x)=(-5x+2)+5

Step-by-step explanation:

The equation for the function of the ordered pair is y =10x+2.

What is equation for the function?

 An equation that has one solution for y for each value of x is referred to be a function. For each input of a particular type, a function assigns precisely one output. The names f(x) or g(x) are frequently used in place of y when naming functions. If our function's value is f(2), then we should calculate its value when x=2. Each functional equation contains some information about a function or several functions. An illustration of a functional equation is f (x) f (y) = x y, f(x) f(y) = x y.

Here in given order pair , let us take any two points,

[tex](x_1,y_1)=(0,2)\\(x_2,y_2)=(1,12)[/tex]

Now using slope formula,

=> slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

=> slope m =10/1 = 10

Now using equation formula,

=> [tex]y-y_1=m(x-x_1)[/tex]

=> y-2 =10(x-0)

=> y-2 = 10x

=> y=10x+2.

Therefore equation of the following order pair is y = 10x+2.

Where:

From the graph of this line, we have the following data points:

Point (x, y) = (-1, 2)

Point (x, y) = (0, -2)

In Mathematics, the slope of any straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (-2 - 2)/(1 - 0)

Slope, m = -4/-1

Slope, m = -4
