Answer:
The values of a and b are -1.28 and 1.28 respectively.
Step-by-step explanation:
It is provided that the area of the standard normal distribution between a and b is 80%.
Also it is provided that a < b.
Let us suppose that a = -z and b = z.
Then the probability statement is
Simplify the probability statement as follows:
Use the standard normal distribution table to determine the value of <em>z</em>.
Then the value of <em>z</em> for probability 0.90 is 1.28.
Thus, the value of a and b are:
Thus, .

Step-by-step explanation:
The sum of 17 and 3 times x is given by the algebraic expression "17+3x" .
A mathematical construct called an algebraic expression is made up of integer constants, variables, and algebraic operations (addition, subtraction, multiplication, division, and exponentiation by a rational exponent).
Let us take an expression 4x³+6xy+9 is an algebraic expression. Where
x,y are variables 4 and 6 are co-efficients and 9 is the constant .
In the above statement it is given that the sum of 17 and times x. Here x is a variable.
3 times x equates to 3x and when 17 is added we get the expression 17+3x.
Hence the required algebraic expression is 17+3x

So convert to quarts
1 gallon=4 quarts
4 quarts=3.35
therfor divide al and al's farm milk by 4 to get 1 quart
3.35/4=0.83
0.83 coparedto 1.29
0.83 is less so it is better deal
Al& AL's farm sels for less
