line segment ab has a slope 5/4 and contains point a(8,-7). what is the y-coordinate of point q(3,y) if qa is perpendicular to l
MArishka [77]
U have a slope of 5/4...a perpendicular line will have a negative reciprocal slope...which means, the slope we need is -4/5.

Now we use y = mx + b
slope(m) = -4/5
(8,-7)
-7 = -4/5(8) + b
-7 = -32/5 + b
-7 + 32/5 = b
-35/5 + 32/5 = b
-3/5 = b

equation is : y = -4/5x - 3/5.....4x + 5y = -3

4x + 5y = -3....when x = 3
4(3) + 5y = -3
12 + 5y = -3
5y = -3-12
5y = - 15
y = -15/5
y = - 3 <===

3. consider rolling a single die. we get the number d of the die. (10 points) a. if i tell you the number is less than 4 (d &lt;
Semenov [28]

The probability of getting an even number, knowing that the number is less than 4, in the rolling of a single die is <u>1/3</u>.

The probability of an event = The number of favorable outcomes to the event/The total number of possible outcomes.

In the question, we are asked to find the probability of getting an even number, considering rolling a single die, where we get the number d of the die, and the number is less than 4 (d < 4).

For the number d, the total number of possible outcomes, given d is less than 4 in the rolling of a single die is 3 {viz. 1, 2, and 3}.

For the event of getting an even number, from all the possible outcomes, the number of favorable outcomes is 1 {viz. 2}.

Thus, the probability of getting an even number, knowing that the number is less than 4, in the rolling of a single die is <u>1/3</u>.
