Theoretical probability is the number of desired outcomes (heads) divided by the total number of outcomes (heads or tails). The actual outcome does not affect the theoretical probability. Mark is correct.

A line passes through the point (4, -6) and has a slope of 3/2 . Write an equation in slope-intercept form for this line.
tatyana61 [14]

A slope intercept form: y = mx + b where m = slope and b = y -intercept

A slope of 3/2 is given

So y = 3/2 x + b

To find b:

b = y - mx

A line passes through the point (4, -6)

b = -6 - (3/2)(4)

b = -6 - 6

b = - 12

Answer

Equation in  slope intercept form:  y = 3/2 x - 12

Show answer in lowest terms. 25/75+ 25/125=
Anit [1.1K]
Hi Jujub! To find the answer in lowest terms, first you have to find the lowest common denominator. To find this, find the lowest common multiple of 75 and 125, which is 375. Now, to make the common denominator, you have to make equivalent fractions. 375 ÷ 75 = 5, and 5 × 25 = 125. So the new fraction is 125/375.  Now the same thing for 25/125.  375 ÷ 125 = 3, and 3 × 25 is 75. So the new fraction is 75/375.  Now add the new fractions:  
125/375 + 75/375 =  200/375

This answer can be simplified to 8/15.
