A. Well she starts with 24 buns. She ate 1/2 half of a bun leaving 23 1/2 buns left. Then she gave her mother and father a bun each so you do 23 1/2 - 2 which gets you 21 1/2 buns. So the total number of buns that she has left is 21 and 1/2 buns.
Answer:
Answer: |
1/(a b x y)
Step-by-step explanation:
Simplify the following:
(x^2 y^2 m n x^8 y^9 m n)/(x^11 y^12 m^2 n^2 a b)
Combine powers. (m n x^8 y^9 m n x^2 y^2)/(a b m^2 n^2 x^11 y^12) = (m^(1 + 1 - 2) n^(1 + 1 - 2) x^(8 + 2 - 11) y^(9 + 2 - 12))/(a b):
(m^(1 + 1 - 2) n^(1 + 1 - 2) x^(8 + 2 - 11) y^(9 + 2 - 12))/(a b)
1 + 1 - 2 = 0:
(m^0 n^(1 + 1 - 2) x^(8 + 2 - 11) y^(9 + 2 - 12))/(a b)
1 + 1 - 2 = 0:
(m^0 n^0 x^(8 + 2 - 11) y^(9 + 2 - 12))/(a b)
8 + 2 - 11 = -1:
(m^0 n^0 x^(-1) y^(9 + 2 - 12))/(a b)
9 + 2 - 12 = -1:
(m^0 n^0 y^(-1))/(x a b)
n^0 = 1:
m^0/(a b x y)
m^0 = 1:
We have the equation of the line as follows:
y = 0.5x + 79
We want to calculate the melting point (the y value) of DNA with 50% gc content (the x value).
The gc content represents the value of x in the equation, so to calculate the melting point (y), we will simply substitute the x with 50 in the equation of the line as follows:
melting point = 0.5(50) + 79 = 25 + 79 = 104 degrees
The answer is
<span>D) If x=19, then 2x-3=35
proof
</span>
If x=19, 2(19)-3=38-3=35 so <span> If x=19, then 2x-3=35 is verified
</span>if <span>2x-3=35, so </span><span>2x=35 + 3, </span><span><span>2x=38 implies x = 19, so x =19 is verified
</span> </span>
<span>If x=19 if and only if 2x-3=35

Answer:
P(x< 18) = 0.986
Step-by-step explanation:
Step 1: find the z-score using the formula, z = (x - µ)/σ
Where,
x = randomly chosen values = 18
µ = mean = 7
σ = standard deviation = 5
Proportion of the population that is less than 18 = P(x < 18)
Plug in the values into z = (x - µ)/σ, to get z-score.
z = (18 - 7)/5
z = 11/5 = 2.2
Step 2: Find P(x< 18) = P (z<2.2) using z-table.
The probability that corresponds with z-score calculated is 0.986.
Therefore,
P(x< 18) = 0.986
