Answer:
And we can find this probability with the complement rule and with the normal standard table and we got:
Step-by-step explanation:
Let X the random variable that represent the patient recovery time of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And we can solve this problem using the z score formula given by:
And using this formula we got:
And we can find this probability with the complement rule and with the normal standard table and we got:
Answer:
y = (x/(1-x))√(1-x²)
Step-by-step explanation:
The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:
x = r·cos(θ)
y = r·sin(θ)
x² +y² = r²
__
r = sec(θ) -2cos(θ)
r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)
r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²
(x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations
x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor
y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)
__
The attached graph shows the equivalence of the polar and rectangular forms.
Answer:
179/495
Step-by-step explanation:
x = 0.3616161.......... ---------------(I)
Multiply by 1000
1000x = 361.616161......
Multiply (I) by 10
10x = 3.616161........
1000x = 361.6161......
<u> 10x = 3.6161........ </u> {Now subtract}
990x= 358
x = 358/990
x = 179/495
Answer:
x=23
Step-by-step explanation:
100=51+3+2x
46=2x
plz brainleist :)
P(x) = 200.000 - 25x --> from (65-40)
breakeven
200000 = 25x
x = 8000
hope this help
