Answers

Answer 1

The population proportion of women athletes who graduated from the university is more than 67%.

A random sample  of 40 women athletes at the school showed that 23 eventually graduated.

n=40 , X=23 , p0 =67% = 0.67 , alpha = 1% = 0.01

H0: : p0 = 0.67  Vs  H1 : p0 < 0.67

Test statistics = (p-p0) / (square root ((p0(1-p0) / n))

p=X/n

H0::p0=0.67  Vs  H1:p0<0.67

Test statistics = z = (p-p0) / ( square root ((p0(1-p0)/n))

p=X/n=23/40

z = (0.575-0.67) / (square root (0.67(1-0.67)/40))=-1.278

P - value = P(z < -1.278) = 0.1007

Since the p-value is  0.1007 that is less than the level of significance the decision is to reject the null hypothesis. In conclusion, there is a sufficient evidence to support that the population proportion of women athletes who graduated is now more than 67%.

What is median class example?

Answers

The continuous data that is presented as a frequency distribution makes up the median of the grouped data.

The center number in the set of data, known as the median, is what divides the data set's upper and lower halves. Since the data is divided into class intervals, the middle value is unknown when calculating the median of grouped data.

Let us understand this with the help of a median class example.

Consider the data as 48, 20, 59, 69,73. We have to calculate the median.

Arranging in ascending order we get, 20, 48, 59, 69, 73.

Here the number of observations is n = 5.

To find the median of odd data we will use the formula:

[(n+1)/2] = (5+1)/2 = 3.

Therefore, median = 3rd observation.

Median = 59.

Hence we got the idea of the median with the example of class.

How do you determine if a triangle is SSS SAS or ASA?

Answers

SSS Stands on Side - Side - Side

SAS Stands on Side - Angle - Side

ASA Stands for Angle - Side - Angle.

There are three theorems that may be used to determine whether two triangles are similar: Angle - Side - Angle (ASA), Side - Angle - Side (SAS), and Side - Side - Side (SSS).

SSS, which stands for "side, side, side," denotes that there are two triangles with identical angles on all three sides. The triangles are congruent if their third sides are the same as those of another triangle.

That is what the SAS regulation says. The triangles are congruent if the two sides and included angle of one triangle are the same as the two sides and included angle of another triangle. Any angle that is created by two specified sides is an included angle.

According to the ASA postulate of Euclidean geometry, two triangles are similar if their two corresponding angles are congruent and one side is equal to the corresponding side of the other triangles.

In a series of transformations, which transformation would make two figures similar as opposed to congruent? answer choices.
a. translation
b. dilation.
c. reflection.
d. rotation.

Answers

A: dilations

Reasoning:

By definition, translations, rotations, and reflections preserve the congruence and collinearity of points on figures transformed from the pre-image to the image. This means that the transformed figure has the exact same dimensions: congruent angles, sides, location of points. On the other hand, dilations are a type of transformation that create similar figures. Similar figures are proportional, so they have congruent angles, and thus they are the same shape, but their side lengths are proportional. So, they look like a copy of the original figure, but either enlarged or reduced by a factor, called the scale factor or “k.”

What is a Line Segment?

A line segment is a portion of a straight line that is defined by two points. It is a one-dimensional geometric figure with no width or area. Line segments can be drawn in many ways, including straight, curved, or jagged. The length of a line segment is the distance between the two points that define it. Line segments are commonly used to measure distances, form shapes, and construct geometric figures. Line segments can be used to define polygons, circles, and other shapes. Line segments are also used in mathematics to represent vectors and calculate angles. Line segments are a fundamental element of geometry and are used in a variety of applications, including navigation, construction, engineering, and computer graphics.

We have,

PS= RS = 31,

To find the vertical asymptote, take the limit of the function as x approaches infinity or negative infinity. To find the horizontal asymptote, take the limit of the function as x approaches the endpoints of the domain.

To find the vertical asymptote of a function, take the limit of the function as x approaches either infinity or negative infinity. This will give the value at which the output of the function approaches infinity or negative infinity, respectively. To find the horizontal asymptote, take the limit of the function as x approaches the endpoints of the domain. If the limit of the function as x approaches the endpoint is finite, then the horizontal asymptote is the value of the limit. If the limit of the function as x approaches the endpoint is infinite, then the horizontal asymptote is undefined. If the limit of the function as x approaches the endpoint is undefined, then the horizontal asymptote is undefined.

Answers

After 6 years the population of goats on the small island reaches 1000.

What is per capita growth rate?

It is the rate of increases of population per individual in the population. The term related to time period and entire population.

How to calculate the time to reach the maximum population

given, initial population of goat on the smallest island, N° =2,

after t years the population of goats on this island, N= 1000

the maximum goat carrying capacity of this island, K= 1500

per capita growth rate, r = 0.5 per year

now, we use logistic growth equation, dN/dt = r×N[(K-N)/K]

                                                           dN/dt = 0.5×1000{1500-1000)/1500}

The third number in this sequence is 23.

The sum of three consecutive odd numbers can be written as (2n-1) + (2n+1) + (2n+3) = 69, where n is a positive integer. Expanding the left side gives us 6n+1 = 69, which means n = 11. The third number in the sequence is (2n+1) = (2 × 11+1) = 23. Therefore, the third number in the sequence is 23.

In the given sequence, 1, –3, 9, –27, 81,..., each number is multiplied by -3 to get the next one in the sequence.

How do you find the degree and the number of turning points in a polynomial function?

Answers

To find the degree of a polynomial function, count the number of terms in the expression. To find the number of turning points, take the degree of the polynomial and subtract 1. The number of turning points will be equal to that number.

To find the degree of a polynomial function, the first step is to count the number of terms in the expression. For example, if the expression is 3x^2 + 4x + 2, then the degree is 2 because there are three terms.The second step is to subtract 1 from the degree of the polynomial. In the example, subtracting 1 from 2 gives us 1. Therefore, the polynomial has 1 turning point.A turning point is a point on the graph of the polynomial where the slope of the tangent line is 0. This means the graph changes direction at the turning point. In the example, the graph changes direction at the point (1, 5).In summary, to find the degree and the number of turning points in a polynomial function, count the number of terms in the expression to find the degree, then subtract 1 from the degree to find the number of turning points.

Answers

Answer:

1) x = 29; m∠3 = 6º

2a) scalene

2b) acute

Step-by-step explanation:

1) We can first solve for m∠3, as it is supplementary to 174º.

174º + m∠3 = 180º

m∠3 = (180 - 174)º

m∠3 = 6º

Then, we can solve for x by setting the sum of the measures of the interior angles of the triangle to 180º.

m∠1 + m∠2 + m∠3 = 180º

↓ substitute in given and solved values

(3x + 2)º + (5x - 60)º + 6º = 180º

↓ combine like terms

8xº - 52º = 180º

↓ add 52 to both sides

8xº = 232º

↓ divide both sides by 8º

x = 29

2a) We know that this triangle is not equilateral, as the measure of one of its interior angles (m∠3) is 6º. However, the triangle may be isosceles if m∠1 = m∠2. We can check for that by substituting x into each angle measure expression.

m∠1 ≟ m∠2

(3x + 2)º ≟ (5x - 60)º

↓ substitute in x-value

3(29)º + 2º ≟ 5(29)º - 60º

↓ simplify

(87 + 2)º ≟ (145 - 60)º

89º ≠ 85º

m∠1 ≠ m∠2; the triangle is not isosceles. Therefore, it must be scalene.

2b) All of the triangle's angles are less than 90º. Hence, it is an acute triangle.
