Oh bro big rip I need help on math too it’s not a fun class
Answer:
8 1/6
Step-by-step explanation:
7/3 x 7/2
= 49/6
= 8 1/6
Answer and Step-by-step explanation: This function is a probability density function of a random variable X:
and to calculate probabilities, we will have to integrate it:
Solving:
Then:
a. P(X < 5)
P(X < 5) = 0.683
b. P(X < 9)
Since density function's upper limit is 8, probability of x < 9 is 100% or 1.
So, P(X < 9) = 1
c. P(5 < X < 7)
P(5 < X < 7) = 0.273
d. P(X > 3)
P (X > 3) = 0.683
e. P(X < x) = 0.95
Solving this cubic equation, we have three values for x:
x₁ = -3.909
x₂ = 8.992
x₃ = 6.917
The value of x will the one between 0 and 8, which are the limits of the function. So, value of x which gives a probability of 0.95 is x = 6.917.
I think it’s D I’m not sure
Answer: y=1/4x-5
Step-by-step explanation:
<em>1/4 is the slop</em>
<em>-5 is the y-intercept</em>
<em>Y=mx+b (slope-intercept form)</em>
<em>m=slope</em>
<em>b=y-intercept</em>
<em>y=1/4x-5</em>
