Course Activity: Relationships Betwee
Alenkinab [10]

Answer:

yes

Step-by-step explanation:

A rational number is in the form p/q where p and q are both integers and the denominator q is not equal to zero. This means that the set of all real numbers are rational numbers.

Since q can be any integer apart from zero, it means that all integers are rational numbers i.e for q = 1.

Hence 2 which can be written as fraction as 2/1 is a rational number since the denominator (q = 1) is a non zero number

Point M is the midpoint of PQ. The coordinates of P and M are given below.
Zepler [3.9K]

The coordinates of Q are (-1,6)

Further Explanation:

Given points are:

(x_m, y_m) = (5, -2)\\(x_p,y_p) = (11, -10)

The formula for mid-pint is:

(x_m, y_m) = (\frac{x_p+x_q}{2} , \frac{y_p+y_q}{2})\\From\ this\ we\ get\\x_m = \frac{x_p+x_q}{2}\\Putting\ values\\5 =\frac{11+x_q}{2}\\5*2 = 11+x_q\\10 = 11+x_q\\10-11 = x_q\\x_q = -1\\AND\\y_m = \frac{y_p+y_q}{2}\\-2 = \frac{-10+y_q}{2}\\-2*2 = -10+y_q\\-4 = -10+y_q\\-4+10 = y_q\\y_q = 6

The coordinates of Q are (-1,6)

What is the mean absolute deviation<br> 4 2 2<br> of the following set of data?<br> 10
mina [271]

Answer:

<em>mean absolute deviation would be 2.75</em>

Step-by-step explanation:

mean: 4 + 2 + 2 + 10 = 18/4 = 4.5

4.5 - 4 = 0.5

4.5 - 2 = 2.5

4.5 - 2 = 2.5

4.5 - 10 = 5.5

mean absolute deviation: 0.5 + 2.5 + 2.5 + 5.5 = 11/4 = 2.75

~hope this helps~

please mark me the brainliest, I would highly appreciate it :)
