the probability

(a) The student is enrolled in mathematics= $\frac{110}{450} =0.244\\$

(b) The student is enrolled in English.= $\frac{205}{450} =0.456\\$

(c) The student is enrolled in both.= $\frac{50}{450} =0.111\\$

(d) The student is enrolled in mathematics or English.= $\frac{110+205-50}{450} =0.589\\$

(e) The student is enrolled in English but not in mathematics.

= $\frac{205-50}{450} =0.344\\$

What would the sum of -18-(-12) be?

Mademuasel [1]

-18-(-12)=-6
Since there is two negative sign, it turns into positive meaning the -12 becomes positive 12 and the -18 stays same. So -18+12=-6 because 18 is bigger than 12 and it's negative so the final answer should be negative.
Hint: when you see two negative sign just turn them into plus sign.

Find the midpoint of the segment with the given endpoints. (9,9) and (-1,- 3)

GenaCL600 [577]

Answer: (4, 3)

Step-by-step explanation:

The formula for coordinate of the mid point is given as :

Mid point = ( $\frac{x_{2}+x_{1}}{2}$ , $\frac{y_{2}+y_{1}}{2}$ )

$x_{1}$ = 9

$x_{2}$ = -1

$y_{1}$ = 9

$y_{2}$ = -3

Substituting the values into the formula , we have :

Mid-point = ( $\frac{-1+9}{2}$ , $\frac{-3+9}{2}$ )

Mid-point = ( $\frac{8}{2}$ , $\frac{6}{2}$ )

Mid - point = ( 4 , 3)
