Answer:
Its in the one place
Step-by-step explanation:
We will choose x=2
Plug in x=2 as the input:
f(2)=5(2)+13
Use PEMDAS to simplify:
f(2)=10+13
f(2)=23
Answer:
Percentile 5
And if we solve for a we got
Percentile 95
And if we solve for a we got
Step-by-step explanation:
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where
and
We want to find the percentiles 5 and 95 for this case.
Percentile 5
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
We want to find a percentile with 0.95 of the area on the left and 0.05 of the area on the right it's z=-1.64. On this case P(Z<-1.64)=0.05 and P(z>-1.64)=0.05
Using this condition we got:
Replacing we got:
And if we solve for a we got
Percentile 95
And if we solve for a we got
S=S1+S2, where S1=12*4=48 cm², S2=0.5*(12-3-3)*(8-4)=12 cm².
S=48+12=60 cm²
-8x-2y=-24
-2y=-24+8x
2y=24-8x
Y=12-4x
Y=-4x+12
