Since line m and line n are parallel, that means 45° and (2x-5)° add up to 180°
45+(2x-5)=180
2x-5=135
2x=140
x=70

Answer:
Refer below
Step-by-step explanation:
a) a and b are the lower and higher values of the interval for which uniform distribution is defined.
Here a= 6 and b =10
b) Mean of the uniform distribution= (a+b)/2 = (6+10)/2 =8
Or int x (1/4) dx = x^2/8 = 8
c) Variance of the uniform distribution = (b^2-a^2)/12 = (100-64)/12
= 36/12 =3
Std dev = sq rt of 3 = 1.732
d) To find total area
PDF of the distribution = 1/(b-a) = 1/4, 6<x<10
Area = \int 6 to 10 of 1/4 dx
= x/4
Subtitute limits
= (10-6)/4 =1
So total area = 1
d)P(X>7) = int 7 to 10 of 1/4 dx = 3/4
e) P(7<x<9) = Int 7 to 9 of 1/4 dx = 2/4 = 1/2
The answer is 8 choices.
To calculate this, a multiplication rule is used. The multiplication
rule calculates the probability that both of two events will occur. In this
method, the possibilities of each event are multiplied.
We have three events occurring together:
1. Orlando has 2 options: to wear either navy blue or black.
2. Orlando has 2 options: to wear a coat with short or long tail.
3. Orlando has 2 options: to wear <span>a solid or striped cummerbund.</span>
<span>
</span>
<span>Using the multiplication rule, the number of choices is multiplied, thus he has in total 8 options:</span>
<span>2 </span><span>· 2 </span><span>· 2 = 8</span>
If this is algebra then I can help
You would take the -9 and add 9 to it, that would cancel out the -9 but you would have to put it on the opposite side of the equation, that would show it as this: y=41+9, then you would simplify it to this: y=50
