Let x = ounces of $35 perfume
Let y = ounces of $15 perfume.
We want a 3-ounce perfume, therefore
x + y = 3
or
y = 3 - x (1)
We want the 3-ounce perfume to cost $63. Therefore
35x + 15y = 63 (2)
Substitute (1) in (2).
35x + 15(3 - x) = 63
35x + 45 - 15x = 63
20x = 63 - 45 = 18
x = 18/20 = 0.9
From (1), obtain
y = 3 - 0.9 = 2.1
Answer:
0.9 ounces of $35 perfume and 2.1 ounces of $15 perfume.
So when ur trying to divide fractions that can't really "happen" for one u may not get the correct answer so u (KCF) which would mean "keep change flip" so this is what u should get
See what we did there? We switch the second fraction and instead of division we did multiplication so then if u multiply across you should get
Then find the greatest common factor which is 2 then divide both of them by two straight across then u would get
Cause 6 divided by 2 =3
And 10 ÷2 =5
Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
Answer:
<em>EX=2.68 ≈ 3</em>
<em>Lakeside Olds should expect 3 automobiles lined up at opening</em>
Step-by-step explanation:
<u>Expected Value of a Discrete Probability Distribution</u>
Given a discrete probability distribution of values
x={x1,x2,x3...,xn}
And probabilities
p={p1,p2,p3,...,pn}
Provided the sum of all probabilities is 1, then the expected value of the distribution is
EX =
The data refers to the number of automobiles lined up at Lakeside Olds at opening time for service:
x={1,2,3,4}
And probabilities
p={ 0.40 , 0.03 , 0.06 , 0.51 }
Checking the sum: 0.40 + 0.03 + 0.06 + 0.51 = 1
Now compute the expected value
EX= 1*0.40+2*0.03+3*0.06+4*0.51
EX=2.68 ≈ 3
Lakeside Olds should expect 3 automobiles lined up at opening
