X= 75
the equation is
is/of %/100
48 = is
64 = %
X = of
100 = 100
48 X 100 = 4,800
64 X x = 64x
64x / 64 = x
4800 / 64 = 75
<span>SO... x = 75</span>
Answer:



Step-by-step explanation:
Given
Let
A = Event of being a universal donor.
So:


Solving (a): Mean and Standard deviation.
The mean is:



The standard deviation is:




Solving (b): P(x = 3)
The event is a binomial event an dthe probability is calculated as:

So, we have:




Answer:
The equation the 16 x 6 = 96
and she would have 6 bags of dog treats
Step-by-step explanation:
<span>Each hot dog costs $ 1.50 and each soda costs $ .50. You made a total of $ 78.50. You sold a total of 87 hot dogs and sodas combined. You must report the number of hot dogs and soda's sold. How many hot dogs and soda's were sold?
Quantity Equation: h + s = 87
Value Equation:: 1.5h+0.5s=78.50
Multiply thru the Quantity Equation by 15
Multiply thru the Value Equation by 10.
15h + 15s = 15*87
15h + 5s = 785</span>Subtract and solve for "s":<span>10s = 520
</span>s = 52 (# of soda's sold)
<span>
Solve for h:
h + s = 87
h + 52 = 87
h = 35 (# of hot dog's sold)</span>
Answer:
= 
Step-by-step explanation:
Differentiate xy using the product rule, then
Given
x - y = xy
1 -
= x.
+ y. 1 = x
+ y ( subtract 1 from both sides )
-
= x
+ y - 1 ( subtract x
from both sides )
-
- x
= y - 1 ( multiply through by - 1 )
+ x
= 1 - y
(1 + x) = 1 - y ← divide both sides by (1 + x)
=
