Answer: 60th

Step-by-step explanation:

First order the values from least to greatest:

47, 49, 61, 76, 79, 88, 92, 92, 94, 94.

We can note that the 88 is the 6th of 10 values, so 6/10 = 0.60 or the 60th percentile.

Theresa is in 60 percentile.

A test that is administered and scored in a consistent, or "standard," manner is known as a standardized test. The questions and interpretations on standardized tests are designed to be consistent and are administered and scored in a predetermined, standard manner.

A standardized test is one in which the same test is given to all test takers in the same way and graded in the same way for everyone.

Given scores

88, 49, 92, 47, 61, 94, 94, 76, 79, and 92.

arrange in increasing order,

47, 49, 61, 76, 79, 88, 92, 92, 94, 94

Theresa got 88, which is sixth term

percent = term x 10

 percent = 6 x 10 = 60%

Hence, she is in 60%.

Answer:

This formula can also be written as \(y - {y}_{1} = m\left(x - {x}_{1}\right)\). The standard form of the straight line equation is \(y = mx + c\) where \(m\) is the gradient and \(c\) is the \(y\)-intercept.

Answer:

a) let x = price of 1 trumpet

let y = price of 1 clarinet

12x + 19y

b)

12x + 19(139.95) = 4578.45

12x + 2659.05 = 4578.45

12x = 1919.4

Answer:

[tex]y = -\frac{3}{7}x + 3[/tex]

Step-by-step explanation:

In order to find the equation of a line, we need to first find the slope. Slope is represented by the formula:

[tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]

where (x1, y1) and (x2, y2) are point on the line. In this case, we can use the points (0, 3) and (7, 0):

[tex]\frac{0-3}{7-0} = -\frac{3}{7}[/tex]

The point (0, 3) is the y-intercept, so given an equation in the form y = mx + b, 3 would be b and we already calculated the slope, which is m. We can plug these values in to get:

[tex]y = -\frac{3}{7}x + 3[/tex]

Answer:

The number of win games are 28

Step-by-step explanation:

x=lost. 2x=win

2x+x=42

3x=42

x=42

3

x=14

win=2x

=2×14

=28

The number of games the sports team won if a sports team won twice as many games as they lost is 28games

Let the amount the sports team lost be x

If the sports team won twice as many games as they lost, then the number of games won will be 2x

If the sum of games won and games lost was 42, then:

x + 2x = 42

3x = 42

Divide both sodes by 3

3x/3 = 42/3

x = 14

Amount of games won = 2(14)

Amount of games won = 28games

Hence the amount of games the sports team won is 28games

The answer is x=34 degrees.

The answer you are looking for is x=34.

Solution/Explanation:

First things first, we need to understand that the sum of the angles of a triangle is 180°. We can apply this fact for the problem.

So, that means that the sum of all of the angles of this triangle is 180°.

So, therefore, we can formulate an equation:

2x+20+2x-10+x=180.

So, we now have our expression.

Now, all we need to do is simplify it.

Combining similar-like terms,

2x+2x+x+20-10=180.

Simplifying it now,

5x+10=180.

Subtracting 10 from both sides of the equation,

5x+10-10=180-10.

5x=170.

Finally, dividing both sides by 5,

5x/5=170/5.

x=34.

So, therefore the final answer is x=34.

I hope that this has helped you. Enjoy your day, and take care!

Answer:

(y+4) /2

Step-by-step explanation:

(y²-16)/(2y+6) × (y+3)/(y-4) =

(y+4)(y-4) / 2(y+3) × (y+3)/(y-4)

=> eliminate all (y-4) and (y+3)

so, we get :

(y+4)/2

The solution of the written expression, ''The sum of a number and 3 is 6 less than twice that number'' is 9.

Here,

The written expression, ''The sum of a number and 3 is 6 less than twice that number''.

We have to solve this expression.

What is Mathematical expression?

An expression consists of one or more numbers or variables along with one more operation.

Now,

Let a number is x.

By the given written expression, we can write the mathematical expression as,

x + 3 = 2x - 6

By solving;

x + 3 = 2x - 6

3 + 6 = 2x - x

9 = x

x = 9

Hence, the value of written expression is x.
