Answer: Equation Classification : A. Possible and Determined;

B. Possible and undetermined and C. Impossible:

Step-by-step explanation:

A. Possible and Determined: These are equations that admit at least one solution.

Example: 2x = 3 → x = 3

B. Possible and undetermined:

They are equations that have infinite solutions.

Example: x + 2 = x + 2 → The unknown x assumes infinite numerical values. Thus, the equation has infinite solutions.

C. Impossible: Has no solution.

Examples:

0x = 4 → Unable to divide 4 by 0.

y = y + 2 → y - y = + 2 → 0 = +2 → There is no equation without unknown.

What is the value of X and Y?

Advocard [28]

Answer:

x = 5.25

y = 7.5

Step-by-step explanation:

Since line 1.5 is parallel to line x which is parallel to line y

then 2/(2+5) = 1.5/x

2x = 7(1.5)

2x = 10.5

x = 5.25

Similarly, 2/(2 + 5 + 3) = 1.5/y

2y = 10(1.5)

2y = 15

y = 7.5

Please help me solve for x

Hello from MrBillDoesMath!

Answer:

sqrt(6)

Discussion:

The triangle, while not indicated, appears to be a right triangle (i.e. has a 90 degree angle). If so, from the Pythagorean theorem,

x^2 + 3^2 = ( sqrt(15) ) ^ 2 =>

x^2 + 9 = 15 => ( subtract 9 from both sides)

x^2 = 15 - 9 = 6 => (take the square root of both sides)

x= sqrt(6)

Complete question :

Rae and Doris are training to swim a 200-meter freestyle race. The table lists their practice times during training camp.

Rae’s Times(minutes)-2.12, 2.01, 2.46, 2, 2.22, 2.31, 2.23

doris times(minutes)-2.32, 2.19, 2.26, 2.03, 2.11, 2.14, 2.07

The median of Raes data is(drop down box answers, 2,2.03,2.14,2.22)minutes,and the median of doris data is(drop down box answers, 2,2.03,2.14,2.22)minutes. The interquartile range for rae is(drop down box answers, 0.01,0.13,0.26,0.30), and the interquartile range for doris is(drop down box answers, 0.02,0.06,0.18,0.19). The two data sets overlap(drop down box answers,very little, a lot

Answer:

Rae's median = 2.22

Rae's IQR = 0.30

DORIS median = 2.14

Doris IQR = 0.19

Step-by-step explanation:

Given :

Rae's time :

Ordered data : 2, 2.01, 2.12, 2.22, 2.23, 2.31, 2.46

Median = 1/2(n+1)th term ; n = 7

Median = 1/2(8) = 4th term

Median = 2.22

Q1 = 1/4(8)th term

Q1 = 2nd term = 2.01

Q3 = 3/4(n + 1)th term

Q3 = 3/4(8)th term

Q3 = 6th term = 2.31

Interquartile range = Q3 - Q1 = 2.31 - 2.01 = 0.30

DORIS Data:

Ordered data: 2.03, 2.07, 2.11, 2.14, 2.19, 2.26, 2.32

Median = 1/2(n+1)th term ; n = 7

Median = 1/2(8) = 4th term

Median = 2.14

Q1 = 1/4(8)th term

Q1 = 2nd term = 2.07

Q3 = 3/4(n + 1)th term

Q3 = 3/4(8)th term

Q3 = 6th term = 2.26

Interquartile range = Q3 - Q1 = 2.26 - 2.07 = 0.19
