Nishad can still win the competition. The minimum score he needs to get for stage presence is: 9.

The formula used  by the judges to determine the scores is: S = 7V + 5M + 3P

Now, Rashida is scored the following: V = 9, M = 7, P = 7

Using the formula, Rashida's score is: 7 * 9 + 7 * 5 + 7 * 3

= 63 + 35 + 21

=  119

Nishad hopes to get V = 9, M = 6, P = ?

7 * 9 + 6 * 5 + 3x

= 63 + 30 + 3x

= 93 + 3x

If x = 9

Then Nishad will have a score of 120, thus winning the competition. The minimum number required of him for stage presence is 9.

Option a. calculate a correlation coefficient is the right response because a correlation coefficient measures the strength and direction of the relationship between two interval level variables.

This is because a correlation coefficient measures the strength and direction of the relationship between two interval level variables. It provides a numerical value that ranges from -1 to 1, where -1 indicates a strong negative correlation, 0 indicates no correlation, and 1 indicates a strong positive correlation.

A scatter plot is also useful in visualizing the relationship between two variables, but it does not provide a numerical value like the correlation coefficient. A test of significance and variance calculation are not typically used as first steps in assessing the relationship between two variables.

Hence, option a. calculate a correlation coefficient is the correct answer.

CP of 1 pencil = 250/100 = 2.5

SP of 1 dozen pencils = Rs.33

SP of 12 pencils = Rs.33

SP of 1 pencil = \frac{33}{12}=2.75

SP>CP

So, Profit% = SP - CP/ CP × 100 = 2.75 - 2.5/2.5 × 100 = 10 %

The expression to represent how much more Elena spent is 4.1 + p.

Two friends shop for fresh fruit. Elena buys a watermelon for ​$8.55 and 5 pounds of cherries. Taniya buys a pineapple for ​$4.45 and 4 pounds of cherries.

Therefore, the expression to represent how much more Elena spent can be represented as follows:

hence,

p = price in​ dollars, per pound of cherries.

Hence,

amount Elena spent more = 8.55 + 5p - (4.45 + 4p)

amount Elena spent more = 8.55 + 5p - 4.45 - 4p

amount Elena spent more = 8.55 - 4.45 + 5p - 4p

Answer:

During the fifth or sixth grade, students are usually asked to divide a mixed number and a whole number. The process is very similar to dividing fractions, but the main difference is that you have to multiply the fraction first before dividing it. This is a simple process. Then, you have to invert the second fraction.

The number of students who like both subjects is 2 students. The result is obtained by using the concept of Venn diagram.

A Venn diagram is a diagram used to represent the sets.

From a survey,

Find the number of students that like both subjects!

We make a Venn diagram to represent the sets, as shown in the attachment.

The universal set is the sum of all students. It is

S = ¼S + ½S + 4

S = ¾S + 4

S - ¾S = 4

¼S = 4

S = 4×4

S = 16 students

Students that like Science are 50%. They are

= 50% × S

= 0.5 × 16

= 8 students

As shown in the picture of Venn diagram, students who don't like Mathematics is 10 students. So, students who only like Science are

b + 4 = 10

b = 10 - 4

b = 6 students

Students who like both subjects are

a = ½S - b

a = 8 - 6

a = 2 students

Hence, students who like Mathematics and Science are 2 students.

let x be the total amount of flour used to makes 30 pie crusts each day

and it is given that each crusts requires  \(\frac{1}{6}\) cup of flour .

so total flour required = \(\frac{1}{6} * 30\) = 5 cups

so we need 5 cups of flour to bake 30 pie crusts

so, x=5 cups

now using this total amount of flour we have to find how cups of flour each pie crusts requires

let each pie crusts requires  \(\frac{1}{y}\) cups of flour .

total flour used in this case = \(\frac{1}{y} * 20\)

and \(\frac{1}{y} *20\) must be equal to 5

The circumcenter is the point of intersection of three perpendicular bisectors of the sides of a triangle. All three of the perpendicular bisectors are congruent, and the circumcenter itself is congruent to itself.

The circumcenter of a triangle is the point of intersection of all three perpendicular bisectors of the sides of the triangle. It is the center of the circumcircle which is the circle that passes through all three vertices of the triangle. The perpendicular bisectors of the sides of the triangle are all congruent, meaning that they are all the same length and have the same angle of inclination. Additionally, the circumcenter itself is congruent to itself, meaning that it has the same location and coordinates. This is because it is the point of intersection of all three perpendicular bisectors, which all have the same coordinates. The circumcenter is an important concept in geometry and trigonometry as it is the center of the circumcircle and provides insight into the properties of the triangle.

Answer:

T is the cost

Step-by-step explanation:

by looking at the question you can see the answer.

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

__

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Each model should be produced on a weekly basis to maximize net profit is $75,900.

What is Net profit?

In both business and accounting, net income or profit is an entity's revenue less cost of goods sold, costs, depreciation and amortisation, interest, and taxes for a certain accounting period.

As given,

Number of products sold:

T ≥ 1.5G

Maximize Profit Z = 150T + 130G

Labor Constraint:

Labor hours Available:

Production Department:

Number of labor hours available per day = 58 × 7 = 406

Number of days in a week = 5

Number of lobor ours available per week = 406 × 5 = 2030

Assembly Department:

Number of labor hours available per day = 25 × 7 = 175

Number of days in a week = 5

Number of labor hours available per week = 175 × 5 = 875.

Labor hours Required:

Labor hours required for G1 model:

Labor hours required at Production department = 3.5G

Labor hours required at assembly department = 2G

Labor hours required for T1 model:

Labor hours required at Production department = 4T

Labor hours required at Assembly department = 1.5T

Total labor hours required at Production department = 3.5G + 4T

Total labor hours required at Assembly department = 2G + 1.5T.

Constraint:

Labor hours required ≤ Labor hours Available.

Production department Labor constraint

3.5G + 4T ≤ 2030

Assembly department Labor constraint:

2G + 1.5T ≤ 875

The function:

Maximum Profit Z = 150T +130G

Constraint:

3.5G +4T ≤ 2030

2G + 1.5T ≤ 875

T ≥ 1.5G

Suppose that for example:

10.5G +12T = 6090

 16G + 12T = 7000

Solve both equations simultaneously,

5.5G = 7000 - 6090

5.5G = 910

    G = 910/5.5

    G = 363

Since, T > G

Hence,

T = 363,

G = 165

Calculate Profit:

150T + 130G = 150 × 363 + 130 × 165

                     = 54450 + 21450

                     = 75900

Hence, each model should be produced on a weekly basis to maximize net profit is $75,900.

The rigid transformations that map line segment RS to line segment R''S'' is rotation of 180° about the origin, followed by the translation (x,y)→(x+1,y+1).

A 180-degree rotation about the origin will alter both X's and Y's signs to the opposite, thus if one of them is negative, the other will be positive, and vice versa.

Point R being (-2,4), the first transformation would include changing the signs to make it (2,-4) and the second transformation would involve adding 1 to both of them:

(x,y) →(x+1,y+1)

(2,-4)→(2+1,-4+1)
