Complete the statement using always, sometimes, or never. A rectangle is __________________ a rhombus.

Lesechka [4]

Hi!

A rectangle can sometimes be a rhombus if it has sides of all equal lengths. If a rectangle was a rhombus, it would also be a square. Furthermore, a square is always a rhombus.

Hope this helps! :)

nlexa [21]

Answer:

4.06

Step-by-step explanation:

Given :

Scores Number of students

0 1

1 2

2 5

3 3

4 6

5 7

6 9

To Find: Mean

Solution:

Mean = $\frac{\text{Sum of all scores}}{\text{number of students}}$

Mean = $\frac{0 \times 1+1\times 2+2\times 5+3\times 3+4\times 6+5\times 7+6\times 9}{1+2+5+3+6+7+9}$

Mean = $\frac{134}{33}$

Mean = $4.06$

Hence, The Mean of baseball score is 4.06 .

Determine the amplitude (A), period (P), and phase shift (PS) of the function f(x)= 3sin(x-4)+9

Tpy6a [65]

ANSWER

D.
$A=3,P=2\pi,PS=(4,9)$

EXPLANATION

The given function is

$f(x) = 3 \sin(x - 4) + 9$

Comparing to the general form of a trigonometric sine function,

$f(x) = A \sin(Bx-C)+D$

$A=3$
The amplitude is absolute value of A

$|A| = |3| = 3$

$B=1$

The period is given by

$p = \frac{2\pi}{ B}$

$p = \frac{2\pi}{ 1} = 2\pi$

$C=4$

is a shift to the right of 4 units.

and

$D=9$

is an upward shift of 9 units

Therefore the phase shift is (4,9).

The correct answer is D
