Answer:

Mean, m = 72

Step-by-step explanation:

It is given that, Carl earned grades of 62, 78, 59, and 89 on four math tests.

It is required to find the mean of his grades.

Mean of a data is given by :

m=\dfrac{\text{sum of observations}}{\text{total no of observations}}

Sum of observations is 62 + 78 + 59 + 89 = 288

Total no of observations are 4

So, mean of his grades is :

m=\dfrac{288}{4}\\\\m=72

So, the mean of his grades is 72.

Help solve 4 and 5 please
Sloan [31]

Answer:

Step-by-step explanation:

4). a). If the diagonals of a parallelogram are congruent, then it must be a RECTANGLE.

b). If the diagonals of a parallelogram are perpendicular, then it must be a SQUARE.

c). If the diagonals of a parallelogram bisect the angles of the parallelogram, then it must be a RHOMBUS.

d). If the diagonals of a parallelogram are perpendicular and congruent, then it must be a SQUARE.

e). If a parallelogram has four congruent sides, then it must be a SQUARE.

5). Given quadrilateral SELF is a rhombus.

a). All sides of a rhombus are equal,

   Therefore, ES = EL = 25

b). Diagonals of a rhombus bisects the opposite angles,

   Therefore, m∠ELS = m∠FLS

    3x - 2 = 2x + 7

    3x - 2x = 7 + 2

    x = 9

c). Diagonals of the rhombus bisect the opposite angles, and adjacent angles are supplementary.

m∠ELF = 2(m∠ELS) = 2(2y - 9)

m∠LES = 2(m∠LEF) = 2(3y + 9)

And 2(2y - 9) + 2(3y + 9) = 180

(2y - 9) + (3y + 9) = 90

5y = 90

y = 18

the sum of two numbers is 41. the smaller number is 13 less than the larger number. what are the numbers
tankabanditka [31]

Answer:

another number =27

Step-by-step explanation:

Let X stand for the larger number. The smaller number is therefore X - 13. We can now write the sum of the two numbers as:

X + (X - 13) = 4

X + X - 13 = 41

Gather the X’s and rewrite as,

2X - 13 = 41

Add 13 to both sides to get

2X = 54

Divide both sides by 2 to solve for X,

X = 27

The graph of F(x) shown below resembles the graph of G(x)- x, but it has been changed somewhat. Which of the following could be
Fudgin [204]

We can solve this question in the following way. Looking at the graph, we see that F(x) is shifted from one unit to the right, and it is represented by | x - 1|. Then, we can multiply this result by 4 to have the final graph, since the graph is not inverted.

Therefore, the answer to this question is F(x) = 4 * | x - 1 |.
