The percentage of students with GPAs greater than 1.66  is 88.22%.

To answer this question, we need to use the empirical rule, which states that 68% of the data is within one standard deviation of the mean. To calculate the percentage of students with GPAs greater than 1.66, we need to subtract the percentage of students with GPAs less than 1.66 from 100%.

The percentage of students with GPAs less than 1.66 can be calculated by subtracting 1.66 from the mean of 2.56, then dividing by the standard deviation of 0.45. This gives us 2.11 standard deviations below the mean, which corresponds to a percentile of 11.78%.

Therefore, the percentage of students with GPAs greater than 1.66 is 100% - 11.78% = 88.22%.

2x + 5x = 3x + 16

I'm wondering if there is an extra "x" on the right hand side,  

anyway

7x -3x = 16

4x = 16

x = 4

see??

Answer:

Step-by-step explanation: Perform any simplification of like terms if possible

7x=3x+16

Collect x terms on one side. Can use the left side for x terms. That means 3x must dissapear. To do this we need to take 3x from both sides.

7x-3x=3x-3x+16

4x=16

To solve for x we need to divide by 4 on both sides

4x/4=16/4

x=4

Answer: x = 64

Step-by-step explanation:

5/8x = 40

We divided by 5/8 from both sides

40/1 divided by 5/8 is the same as

40/1 times 8/5 = 320/ 5 = 64

Answer:

Step-by-step explanation:Charmaine wanted to study how the area of a rectangle changes with the length if its width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then plotted the results and connected them with a line, as shown below. The graph shows the area (in ) versus the length (in ).

Find the range and the domain of the function shown.

Positive and negative signs in limits indicate whether the limit is approaching from the positive side or the negative side. If a amount is approaching from the positive side, the sign is positive; if it is approaching from the negative side, the sign is negative.

When taking the amount of a function, the positive and negative signs indicate the direction in which the limit is approaching. A positive sign means the limit is approaching from the positive side of the function’s domain, while a negative sign indicates the limit is approaching from the negative side. For example, if a limit is written as[tex]$\lim\limits_{x \to 3^+} f(x)$,[/tex]this means the limit is approaching from the positive side of the domain, when x is approaching 3. Similarly, if the limit is written as [tex]$\lim\limits_{x \to 3^-} f(x)$[/tex] this means the limit is approaching from the negative side of the domain, when x is approaching 3. Thus, the positive and negative signs in limits indicate the direction the limit is approaching from.

Answer:

Yes, there is an error in the third step of the solution. The correct result of the third step should be -2x ≤ 8, not -2x ≤ -2. The error occurred because the incorrect value was subtracted from both sides of the inequality

Step-by-step explanation:

The final answer for the inequality 3x − 8 ≤5x + 6 is x ≥ -7, and the third step is wrong, the right answer is -14 ≤ 2x.

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.

Given:

3x − 8 ≤ 5x + 6

Add 8 on both sides of the inequality as shown below,

3x − 8 + 8 ≤ 5x + 6 + 8

3x ≤ 5x + 14

Subtract -3x from both sides as shown below,

3x - 3x ≤ 5x + 14 - 3x

0 ≤ 2x + 14

Subtract 14 from both sides as shown below,

0 - 14 ≤ 2x + 14 - 14

-14 ≤ 2x

Divide both sides by 2 as shown below,

-14 / 2 ≤ 2x / 2

-7  ≤ x

or x ≥ -7

(1) In general, switching the coordinates x and y is how an inverse is calculated.

(2) The function is a one-to-one function and the inverse is also a function if a horizontal line crosses the original function in a single place.

(3) We can find the inverse in algebra by replacing f(x) by y and then solve for x.

In general, switching the coordinates x and y is how an inverse is calculated. Although not strictly a function, this freshly constructed inverse is a relation.

To ensure that the initial function's inverse will be a function, the major purpose must be a one-to-one function. When every second element matches the first value, a function is said to be a one-to-one function.

To determine whether a function is a one-to-one function, use the horizontal line test. The function is a one-to-one function and the inverse is also a function if a horizontal line crosses the original function in a single place.

When a function's formula has been provided to you, follow these steps to discover its inverse:

(1) Change "f(x)" to "y".

(2) Make an effort to resolve the x= equation.

(3) Switch the xs and ys.

Answer:

x = -6

y = -18

Step-by-step explanation:

6x -2y = 0

x - y = 12

Times the second equation by -2!

6x -2y = 0

-2x + 2y = -24

Now add them together and solve for x first!

4x = -24

x = -6

Now put -6 back in the equation and solve for y

6(-6) -2y = 0

-36 - 2y = 0

-2y = 36

y = -18

So, x= -6

Answer:

x = -5 or x = 17

Step-by-step explanation:

The absolute value is the number's distance from 0.

So, we need to write two equations.

x - 6 = 11

x - 6 = -11.

Next, we need to add 6 to both sides of each equations.

11 + 6 = 17

-11 + 6 = -5

So, x = 17 and x = -5.

Answer: It could be -5 or 17

Step-by-step explanation: So, it can be both, but as I see it would most likely be 17 because I see you put x-6 as an absolute value. so, to find the value of x, we could do 11 + 6 (Inverse operations), so 11 + 6 = 17. If it was NOT the absolute value of x-6, we could find it to be -5, by subtracting -6 from 11, to get -5. I hope this helps you understand now, if any questions please comment down below.

Answer:

Step-by-step explanation:

Answer: The image T(V) is defined as the set {k | k=T(v) for some v in V}. So x=T(y) where y is an element of T^-1(S). The preimage of S is the set {m | T(m) is in S}. Thus T(y) is in S, so since x=T(y), we have that x is in S.

Given a function f:A→B, and D⊆B, the preimage D of under f is defined as f−1(D)={x∈A∣f(x)∈D}. Hence, f−1(D) is the set of elements in the domain whose images are in C. The symbol f−1(D) is also pronounced as “f inverse of D.”

In geometry, figures in a plane can be transformed in a variety of ways, including shifts and scaling, to produce new shapes. The new (transformed) shapes are called images and the original, unaltered shapes are called preimages.

Volume is equal to one by third of the Area of the base into Height.

V=(1/3) X A X H, where A is area and H is height.

The sum of a pyramid's side faces makes up the lateral surface area.

LSA of the pyramid multiplied by the base's area gives the total surface area.

A pyramid is a 3D shape that has a base made of a polygon and faces that are all triangular and linked. The conventional form of a pyramid is created by joining each vertex of the base to a single common tip or apex. In this part, let's study more about pyramids.

The area encompassed between a pyramid's faces is referred to as the pyramid's volume. The formula for each pyramid varies based on the pyramid's foundation. The formula used to determine a pyramid's volume, which is expressed in cubic units, is as follows V=(1/3) X A X H.

Different forms of pyramids have varying amounts of surface area. The following formula is used to determine a pyramid's surface area:

Surface Area = Base Area + (½ × Perimeter of the base × Slant height)

When two parallel lines are cut by a transversal, the four angles formed inside the parallel lines are called interior angles.

Interior angles are the angles formed between the two lines and the transversal that lie within the region bounded by the parallel lines. There are always four interior angles formed when two parallel lines are cut by a transversal. These angles are equal in measure and are supplementary to the corresponding exterior angles. In other words, the sum of an interior angle and its corresponding exterior angle is equal to 180 degrees. Understanding the properties of interior angles is important in geometry, as they can be used to prove the parallelism of lines.

To determine if the left end behavior of a polynomial function is rising or falling, you can look at the sign of the leading coefficient of the polynomial. If the coefficient is positive, the left end behavior is rising, and if the coefficient is negative, the left end behavior is falling.

The left end behavior of a polynomial function can be determined by looking at the sign of the leading coefficient. The leading coefficient is the coefficient of the highest degree term in the polynomial. If the leading coefficient is positive, then the left end behavior of the function is rising, because a positive coefficient will cause the function to increase in value as x increases. On the other hand, if the leading coefficient is negative, then the left end behavior of the function is falling, since a negative coefficient will cause the function to decrease in value as x increases. Knowing the sign of the leading coefficient is therefore a quick and easy way to determine whether a polynomial function is rising or falling on its left end.
