When you subtract 10 3/4 - 7 1/4 you will get an answer of 3 1/2
Answer:
Perpendicular
Step-by-step explanation:
-2x+3y=-1
6x+4y=4
----------------
3y=-1-(-2x)
3y=-1+2x
3y=2x-1
y=2/3x-1/3
-----------------
4y=4-6x
4y=-6x+4
y=-6/4x+4/4
y=-3/2x+1
--------------------
2/3 and -3/2 are negative reciprocals, therefore, they are perpendicular.
Answer:
$362.5
Step-by-step explanation:
Given that :
x : _____ 230 ______340 ______ 590
P(x): ____0.25______0.55 _____ 0.20
To obtain the expected value E(x) of the outcome ; we can use the formula :
E(x) = Σ(x * P(x))
E(x) = (230 * 0.25) + (340 * 0.55) + (590 * 0.20)
E(x) = 57.50 + 187 + 118
E(x) = 362.50
Answer:
C
Step-by-step explanation:
It was just in my notes....
14 to 8
14/8 is going to equal 7/4 you get by doing this :<span> </span>
<span>= (14 ÷ 2)/(8 ÷ 2) </span>
<span>= 7/4 </span>
<span>= 1 3/4</span>
