Answer:
Brother's money = $6
Money I have = $18
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
<em>I have 3 times as much money as my brother:
</em>
Money I have = 3x
Where x is the money that my brother has:
Brother's money = x
<em>Our total is $24
</em>
So, 3x+x =24
Solving for x
3x+x=24
4x =24
x =24/4
x = 6
Replacing with the value of x.
Brother’s money = x = $6
Money i have = 3x =3(6) = $18
Answer:
And if we solve for a we got
The 95th percentile of the hip breadth of adult men is 16.2 inches.
Step-by-step explanation:
Let X the random variable that represent the hips breadths of a population, and for this case we know the distribution for X is given by:
Where
and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
We can find a quantile in the normal standard distribution who accumulates 0.95 of the area on the left and 0.05 of the area on the right it's z=1.64
Using this value we can set up the following equation:
And we have:
And if we solve for a we got
The 95th percentile of the hip breadth of adult men is 16.2 inches.
Answer:
-4x + 12
Step-by-step explanation:
2(x+6)-6x
2x + 12 - 6x
combine llike terms
2x - 6x = -4x
-4x + 12
