I don’t know how to do this problem and need help getting answer?

Answers

Hi!!! So to do this problem, you need to find the mean values for each sample. I will walk you through finding the mean of sample 1: first you want to add all of the values for sample 1, which are 4,5,2,4 and 3. Once you add those values you get 18. Then you must divide that 18 by the number of terms you added. The numbers you added were 4,5,2,4 and 3 like I said earlier which is 5 numbers. You divide 18 by 5 to get your mean, which is 3.6

Answer: (B) Sample 2

sample 1 mean = 3.6

sample 2 mean = 4.2

sample 3 mean = 3.8

sample 4 mean = 4

a system of equations is shown below 5x +2y =-15 2x - 2y =-6 what is the solution to the problem

Answers

Answer:

(-3, 0)

Step-by-step explanation:

Let's solve this system using the elimination by addition/subtraction method.  Begin by writing the two equations one above the other:

5x +2y =-15

2x - 2y =-6

Notice that the y terms cancel each other out:

5x +2y =-15

2x - 2y =-6

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

7x        = -21

Dividing both sides by 7 results in x = -3.

Subbing -3 for x in either of the given equations leads to finding y:

5(-3) + 2y = -15, or -15 + 2y = -15.  This results in 2y = 0, or y = 0.

The solution is (-3, 0).

Using the elimination method, the solution to the system of equations is: (-7, -4)

What is the Solution to a System of Equations?

Using the elimination method, the solution to the system of equations is found by adding or subtracting the equations to eliminate one variable, then substitute to find the other.

Given the system of equations:

5x + 2y = -15 --> Eqn. 1

2x - 2y = -6 --> Eqn. 2

Add

3x = -21

x = -21/3

x = -7

Substitute x = -7 into Eqn. 2.

2(-7) - 2y = -6

-14 - 2y = -6

-2y = -6 + 14

-2y = 8

y = -4

The solution is (-7, -4)

The sides of a triangle measure 7, 4, and 9. If the longest side of a similar triangle measures 36, Determine and state the length of the shortest side of this triangle.

Answers

Step-by-step explanation:

Okay! Since these are similar figures we need to find the scale factor in order to answer this question.

We have a triangle with sides 7, 4, and 9. The longest side is 9. This corresponds with the longest side on the similar triangle, which is 36. So to find the scale factor we divide 36 by 9. The scale factor is 4.

Now to find the shortest side of the bigger triangle, we have to find the length of the shortest side on the smaller one which is 4. Since our scale factor is 4, we multiply 4 by 4 to get 16.

The length of the shortest side of the similar triangle is 16

The shortest ide is 16

x = 1. x = -3. So halfway would be at (-1, __).
Sub in -1 into original equation -2x^2 -4x + 6 … -2(-1)^2 -4(-1) + 6 = -2 +4 +6 = 8
So the vertex is (-1,8)


Answer:

Part a:[tex]f(x)=-2(x+1)^2+8[/tex]

Part b: Maximum value

Step-by-step explanation:

Part a.

The given function is [tex]f(x)=-2x^2-4x+6[/tex].

We need to complete the square to obtain the vertex form

[tex]f(x)=-2(x^2+2x)+6[/tex]

Add and subtract the square of half the coefficient of x.

[tex]f(x)=-2(x^2+2x+(1)^2)--2(1)^2+6[/tex]

[tex]f(x)=-2(x^2+2x+1)+2+6[/tex]

The quadratic trinomial within the parenthesis is now a perfect square

[tex]f(x)=-2(x+1)^2+8[/tex]

The vertex form is [tex]f(x)=-2(x+1)^2+8[/tex]

Part b

Comparing [tex]f(x)=-2(x+1)^2+8[/tex] to [tex]f(x)=a(x-h)^2+k[/tex], we have a=-2.

Since a is negative the vertex is a maximum point.

Hence the function has a maximum value

To match each description of an algebraic expression with the symbolic form, we must look for the characteristics that fulfill the given conditions. These include the number of terms, the variables involved, and any constants.

A. 2 terms; variables = x and y: This description does not list a constant, so we are looking for an expression that has only x and y terms. None of the provided options fits perfectly as they all include a constant.

B. 3 terms; variables = x and y; constant = 3: The expression that fits this description is 1. x - 2y + 3.

find the perimeter of this figure

Answers

Answer:

128.52

Step-by-step explanation:

Find the area of the figure by splitting it into two shapes - a trapezoid and a semi-circle.

The area of a semi-circle is found using A = 1/2πr² where r = 6 since the diameter is 12. A = 1/2π(6)² = 56.52.

The area of the trapezoid is found using A = 1/2(a+b)h = 1/2(12 + 6)(8) = 72.

Together the area is 56.52 + 72 = 128.52.

Step-by-step explanation:A polygon is figure with at least 3 straight or definite sides or typically 5 or more straight sides.

Here the polygon we are given is a rectangle.

We know that,

Area of a rectangle = l x w

so we need to measure the length and width of the rectangle to find its area.

If we look closely, we can see the length of the rectangle above the x-axis is 8 units and the length below the x-axis 7 units which makes a total og 15 units.

Answer:

D) 150 square units

Which quadrilateral can have 2 pairs of parallel sides, all sides with equal length, and no right angles.

Answers

Final answer:

The quadrilateral with two pairs of parallel sides, equal side lengths, and no right angles is a rhombus. It can be thought of as a 'pushed over' square without right angles.

Explanation:

The student is asking about a type of quadrilateral that meets certain criteria: it has two pairs of parallel sides, all sides are of equal length, and it has no right angles. A rectangle is a quadrilateral with four right angles, hence it does not meet the criteria since the question specifies no right angles. Considering the traits listed, the quadrilateral in question is a rhombus. A rhombus has all sides of equal length and two pairs of parallel sides, but unlike a square, it does not necessarily have right angles. To visualize, we can think of a 'pushed over' square – if the angles are all acute or obtuse rather than right angles, it qualifies as a rhombus.

A survey found that 78% of high school freshmen have internet acess at home. Of the 754 freshmen at one high school , about how many would be expected to have internet acess at home? SHOW WORK AND EXPLAIN! The person who does show work will be marked as brainliest.

Answers

Multiply the total number of freshman by the percentage:

754 x 0.78 = 588.12

Since you cant have 0.12 of a person, round up to 589 people.

Approximately 589 of the freshmen at the high school would be expected to have internet access at home.

We are given that 78% of high school freshmen have internet access at home. This percentage can be expressed as a fraction or a decimal for calculation purposes. In this case, we will use the decimal form, which is 0.78.

The total number of freshmen at the high school is given as 754.

To find the number of freshmen with internet access, we multiply the total number of freshmen by the percentage (in decimal form) that represents those with internet access.

The calculation is as follows:

 Number of freshmen with internet access = Total number of freshmen × Percentage with internet access

 Number of freshmen with internet access = 754 × 0.78

Performing the multiplication:

 Number of freshmen with internet access = 588.92

In conclusion, about 589 of the 754 freshmen at the high school would be expected to have internet access at home.

1/8 of the boys at a high school tried out for the football team, 1/6 tried out for the baseball team, and 1 /12 tried out for the football team and baseball team. What fraction of those who tried out for football also tried out for baseball?
A)1/12
B) 1/2
C) 1/3
D) 2/3

Answers

Answer:

D) 2/3

Step-by-step explanation:

Let x represent the number of boys at the high school.

1/8x total tried out for football.

1/6 total tried out for baseball.

If we were to draw a Venn diagram, the intersection of the two circles would be the 1/12 of the students that tried out for both, or 1/12x.

Taking this away from the total of 1/8x for football,

1/8x - 1/12x

3/24x - 2/24x

1/24x tried out for just football.

Taking the 1/12x away from the 1/6x that tried out for just baseball,

1/6x - 1/12x

4/24x - 2/24x

2/24x = 1/12x tried out for just baseball.

Looking at those that tried out for football, 2/24 tried out for both and 3/24 total tried out for football.  This means 2 out of 3, or 2/3, of the football try outs also tried out for baseball.

2 / 3 are the required fraction of the boys who tried out for football and also tried out for baseball. OPtion D) is correct.

Given that,
1/8 of the boys at a high school tried out for the football team,
1/6 tried out for the baseball team, and 1 /12 tried out for the football team and baseball team.
What fraction of those who tried out for football also tried out for baseball is to be determined.

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
The fraction of boys that tried out for football also tried out for baseball.
= (1 / 6 - 1 / 12) / 1 / 8
= 2 / 24 * 8 / 1
= 2 / 3

Thus, 2 / 3 are the required fraction of the boys who tried out for football and also tried out for baseball. Option D) is correct.

Final answer:

Correlation in statistics is the relationship between two variables that can be positive, negative, or non-existent. Positive correlation means both variables move in the same direction, while negative correlation means they move in opposite directions. 'Prime correlation' is not a recognized term in statistics.

Explanation:

In statistics, the term correlation refers to the statistical relationship between two variables. A correlation can be positive, negative, or there might be no correlation.

No correlation implies that there is no noticeable relationship between two variables. If one variable changes, we can't predict any specific change in the other.There is no such term as prime correlation in statistics. It might be a typo or unrelated to the concept of correlation.A positive correlation signifies that as one variable increases, the other does too. Similarly, if one variable decreases, the other follows. An example could be the more hours one studies, the better their exam performance.A negative correlation means that as one variable increases, the other decreases. For instance, the more time one spends watching TV, the lower their productivity might be.
