Answer:
0.0959
Step-by-step explanation:
There are 18+24+7+25=74 coins in the jar
Let's call
P(p) = 18/74 the probability of grabbing a penny
P(d) = 24/74 the probability of grabbing a dime
P(n) = 7/74 the probability of grabbing a nickel
P(q) = 25/74 the probability of grabbing a penny
What is the probability that you reach into the jar and randomly grab a dime and then, without replacement, a nickel?
Here we want to find P(n | d) the probability of grabbing a nickel given that you already grabbed a dime.
By the Bayes' Theorem
Now,
P(d | p) = 24/73 since there are now 73 coins and 24 dimes.
Similarly,
P(d | d) = 23/73 for you already grabbed a dime
P(d | n) = 24/73
P(d | q) =24/73
Replacing in the Bayes' formula
So
P(n | d) = 0.0959
Answer:
H0 : u = 45
H : u not equal to 45

Note: I'm not going to type in case sensitive or correct grammer so it's not my fault if you paste my answer and the program says it's wrong
y=mx+b
m=slope
b=y intercept
the x intercept is where the line crosses the x axis or where y=0
the y intercept is where the line crosses the y axis or where x=0
so
for the slope, solve for y
Ax+By=C
minus Ax both sides
By=-Ax+c
divide both sides by B
the slope is
and the y intercept is at
find x intercept
set y=0
Ax+By=C
Ax+B(0)=C
Ax=C
divide both sides by A
the x intercept is at
or the point
slope is
the x intercept is at
or the point
the y intercept is at
or the point
Answer:
No solutions
Step-by-step explanation:
Hello!
To solve for x, we should expand the parenthesis and isolate the variable x.
<h3>Solve for x</h3>
- 6(1 + 5x) = 5(1 + 6x)
- 6 + 30x = 5 + 30x
- 6 ≠ 5
The are no solutions for x, as 6 does not equal to 5.
