A school administrator believes that the mean class gpas for a given course are higher than the preferred mean of 2.75 at a sign
Svetach [21]

The mean GPA is greater than 2.75.

<h3>What is GPA?</h3>
  • A grade point average is a figure that represents the average of the final grades obtained in courses over time.
  • A student's grade point average, sometimes known as a GPA, is computed by adding all accumulated final grades and dividing the total by the number of grades granted.

To find the GPA:

  • GPA is calculated and could be utilized by the college to tell choices, which include the subsequent educational progression.
  • Divide the total range of grade factors earned with the aid of the total number of letter-graded units undertaken.
  • Mean GPA = total/50
  • = 2.75.

Therefore, the mean GPA is greater than 2.75.

Which statement is true about f(x) = –6|x + 5| – 2?
Ad libitum [116K]
The graph of f(x) opens upward

For the values of x < -5 the function is a line with negative slope, for the values of x > - 5 the function is a line with positive slope.

The two lines intercept in the point (-5,-2). That is the vertex of the function; a minimum value. So, all the other points are above the line y = -2.

What ks the % of 4 = 2​
Fittoniya [83]

Answer:

50\%

Step-by-step explanation:

Let x be the percentage then...

x\%(4)=2

Start by dividing both sides by 4:

x\%=\frac{2}{4}

Simplify the fraction:

x\%=\frac{1}{2}

Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.

x\%=\frac{1}{2}*\frac{50}{50}\\x\%=\frac{50}{100}\\x=50\%
