Given that a <span>store is selling two mixtures of nuts in 20-ounce bags: peanuts and cashews.
Let the cost of one ounce of peanut be x and the cost of one ounce of cashew be y, then
Given that </span>t<span>he first mixture has 15 ounces of peanuts combined with five ounces of cashews, and costs $4.25 implies that 15x + 5y = 4.25
Also, given that </span>t<span>he second mixture has five ounces of peanuts and 15 ounces of cashews, and costs $6.75 mplies that 5x + 15y = 6.75
To obtain the cost of </span><span>one ounce of peanuts and one ounce of cashews, we solve the two equations above, simultaneously:

Therefore, </span><span>
one ounce of peanuts and one ounce of cashews cost $0.15 and $0.40 respectively.</span>
Answer:
Limits for B scores
( 79,2 ; 92 )
Step-by-step explanation:
The interval we are looking for is between 6 % and 59%
p₁ = 6 % p₁ = 0,06
As this point is at the right tail of the bell we better look for
p = 1- 0,06 p = 0,94
In z-table z score for 0,94062 is: z₁ = 1,56 ( 0,94062 ≈ 0,94 )
Doing the same to find z₂ score for 59% or 0,59
In z-table again
p = 0,59
z₂ = 0,023
Now we know
1,56 * σ = x₁ - 79
1,56*8,4 + 79 = x₁
x₁ = 92,10 or x₁ = 92
And
0,023*8,4 + 79 = x₂
x₂ = 79,19 or x₂ = 79,2
The rule to describe this transformation is reflection
Answer:
<h2>(f•g)(10) = 37</h2><h2 />
Step-by-step explanation:
(f•g)(x) = (x - 4)² + 1
then
(f•g)(10) = (10 - 4)² + 1 = 6² + 1 = 37
G(x)=9
f(g(x))= 9(2)+9+2=29
