Step-by-step explanation:
prob blue = 3/12 = 1/4
since you are replacing ,
prob(blue, blue) = (1/4)(1/4) = 1/16
Answer:
-7
Step-by-step explanation:
For each ounce of the product, let
x = ounces of moisturizing lotion used,
y = ounces of self-tanning lotion used.
The sum of the two lotions per ounce is equal to one ounce. Therefore
x + y = 1 (1)
Moisturizing lotion costs $0.70 per ounce.
Self-tanning lotion costs $22 per ounce.
Because the product costs $1.30 per ounce. Therefore
0.70x + 22y = 1.30 (2)
From (1), obtain
y = 1 - x (3)
Substitute (3) into (2).
0.70x + 22(1 - x) = 1.30
0.70x - 22x + 22 = 1.30
-21.3x = -20.7
x = 0.9718 ounces
From (3), obtain
y = 1 - 0.9718 = 0.0282 ounces.
A batch of the product is 700 ounces. Therefore the amount of self-tanning lotion used is
700*y = 700*0.0282 = 19.74 ounces
Answer: 19.74 ounces
Answer:
y = -17.25
Step-by-step explanation:
y/23 = -3/<em>4</em>
<em>by</em><em> </em><em>cross</em><em> </em><em>multiplication</em><em> </em><em>❌</em><em> </em><em> </em><em>;</em><em>;</em><em>;</em>
<em>4</em><em>×</em><em>Y</em><em> </em><em>=</em><em> </em><em>23</em><em>×</em><em> </em><em>(</em><em>-3</em><em>)</em>
<em>4y</em><em> </em><em>=</em><em> </em><em>(</em><em>-69</em><em>)</em>
<em>y</em><em> </em><em>=</em><em> </em><em>-69</em><em>/</em><em>4</em>
<h3><em>y</em><em> </em><em>=</em><em> </em><em>-17.25</em></h3>
