The significance level is set at 5% and the probability of the result is 3.6% which is less than the significance level. The result is statistically significant

Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur or that a particular statement is true

The probability of the treatment group’s mean being greater than the control group’s mean by 8 points or more will be:

= (26 + 8 + 2)/1000

Answer:

436.42 m

Step-by-step explanation:

We are to determine the perimeter of the field

perimeter = perimeter of rectangle + perimeter of the two semicircles

Perimeter of a rectangle = 2 x (length + breadth)

2 x (82 + 53) = 270m

Perimeter of a semicircle = 1/2πD

perimeter of the 2 semicircles = 2 x (1/2 x 3.14 x 53) = 166.42

Perimeter = 270 + 166.42 = 436.42 m

For Given Fraction 5/3, The total number of votes is 7648.

What is a fraction?

In Maths, a fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator. The numerator defines the number of equal parts taken, whereas the denominator defines the total number of equal parts in a whole.

For example, 5/10 is a fraction.

Here, 5 is a numerator and 10 is a denominator.

There are four different types of fractions. They are:

Unit Fraction – In a fraction, the numerator with 1 is called a unit fraction. For example, ½, ¼

Proper Fraction – If a numerator value is less than the denominator value, it is called a proper fraction. Example: 7/9, 8/10

Improper Fraction – If a numerator value is greater than the denominator value, then it is called an improper fraction. Example: 6/5, 11/10

Mixed Fraction – If a fraction consists of a whole number with a proper fraction, it is called a mixed fraction. Example 5 ¾, 10 ½

Now,

As given ratio is 5/3 for Yes votes to no votes

so total votes is 5x+38x

and also given that no votes i.e. 3x=2868

Step-by-step explanation: The ratio of apples to oranges is 2:5. That means for every 2 apples there will be 5 oranges.

We want to know how many total pieces of fruit will be in the basket where there are 10 apples.

Lets use the ratio to get the total number of fruits when we have 10 apples.

2:5 there is 2 apples when there is 5 oranges;

4:10 there is 4 apples when there is 10 oranges;

6:15 there is 6 apples when there is 15 oranges;

8:20 there is 8 apples when there is 20 oranges;

10:25 there is 10 apples when there is 25 oranges;

Now simply add the total amount of apples and oranges. 10 + 25 = 35 total fruit.

The shortest distance between the two lines L1 and L2 is 0.

The shortest distance between two lines can be found using the cross product of their direction vectors.

The direction vectors of line L1 and L2 can be found as:

L1 = B - A = (2 - 3, 1 - 2, 0 - 1) = (-1, -1, -1)

L2 = D - C = (3 - 2, 0 - 4, -2 - (-1)) = (1, -4, -3)

The cross product of the direction vectors of L1 and L2 gives the normal vector to the plane formed by the two lines:

cross(L1, L2) = (1 + 4, -1 - 4, 3 + 1) = (5, -5, 4)

The normal vector of the plane formed by the two lines, and a point on line L1 (A = (3, 2, 1)), can be used to find the equation of the plane:

5x - 5y + 4z = d

5 * 3 - 5 * 2 + 4 * 1 = d

15 - 10 + 4 = d

9 = d

So the equation of the plane formed by the two lines is:

5x - 5y + 4z = 9

The shortest distance between the two lines is equal to the distance between a point on line L1 (A = (3, 2, 1)) and the plane formed by the two lines:

d = abs(9 - (5 * 3 - 5 * 2 + 4 * 1)) / sqrt(5^2 + (-5)^2 + 4^2)

d = abs(9 - 9) / sqrt(29)

d = 0 / sqrt(29)

d = 0

Therefore, the shortest distance between the two lines L1 and L2 is 0.

The diameter of the circle is 4.2 units    

The set of circles that have the same radius and same size are known as Congruent circles. In other words, the circles which have the same radius same are known as Congurents circles

Here we have

Circles P and Q are congruent and m∠O = 90°. and RQ = 5

From the data, Circles P and Q are congruent  

Hence, the Radius of Circles P and Q are the same

=> PR = RQ

=> PQ = PR + RQ = 5 + 5  [ Since RQ = 5 = PR ]

=> PQ = 10 ---- (1)

Since, PR = RQ the center, 'O' will be at the same distance from P and Q

=> QO = PO --- (2)

Given that m∠O = 90°  

This implies PQO is an isolated right triangle  

As we know in a right triangle    

=> Hypotenuse² = side² + side²  

=> PQ² = QO² + PO²    

=> (10)² = 2QO²    [ from (1) ]

=> 100 = 2 QO²

=> QO² = 50

=> QO = √50 = 5√2

=> QO = 7.07

From the figure,

The radius of the circle = OQ - Radius of circle Q  

= 7.07 - 5 = 2.1  

Hence, the diameter of the circle = 2 × 2.1 = 4.2

Therefore,

The diameter of the circle is 4.2 units

Step-by-step explanation:

Given that: A college student takes the same number of credits each semester.

They had 8 credits when they started, and after 5 semesters, they had total 58 credits.

Now, In which rate they are earning credits per semester,

for that use the formula:

\(rate=\frac{change of credits}{total no of semeters}\)

rate=50/5

The change in credits is 58-8 = 50, since the

student earned 50 credits in 5 semesters.

So the rate at which they are earning credits per semester is:

Rate = 10 credits per semester.

A right-angled triangle has one of its angles to be 90 degrees

The unknown measurements are:

\(BC = 10.1\)

\(AB = 15.7\)

\(\angle B = 50\)

From the question, we have:

\(\angle A = 40^o\)

\(\angle C = 90^o\)

\(AC =12\)

See attachment for \(\triangle ABC\)

First, we calculate the measure of B

\(\angle A + \angle B + \angle C = 180\)

This gives

\(40 + \angle B + 90 = 180\)

Collect like terms

\(\angle B = 180 - 40 - 90\)

\(\angle B = 50\)

Side length BC is calculated using the following tangent ratio

\(\tan(A) = \frac{BC}{AC}\)

Make BC the subject

\(BC = AC \times \tan(A)\)

So, we have:

\(BC = 12 \times \tan(40)\)

\(BC = 10.1\)

Side length AB is calculated by Pythagoras theorem.

\(AB^2 = AC^2 + BC^2\)

So, we have:

\(AB^2 = 12^2 + 10.1^2\)

\(AB^2 = 246.01\)

Take positive square roots of both sides

\(AB = 15.7\)

Hence, the unknown measurements are:

The only graph that represents a function is: Graph D

A function is defined as a relationship or expression that involves one or more variables. It typically has a set of input and outputs.  Each input has only one output. The function is the description of how the inputs relate to the output.

A function is a relation which describes that there should be only one output for each input (or) we can say that a special kind of relation (a set of ordered pairs), which follows a rule i.e., every X-value should be associated with only one y-value is called a function.

From the graphs, we can see that:

Graph A has 2 outputs at x = -2
