What is the probability that a value picked at random from the standard normal distribution will be between -1.96 and 1.96?
Answers
Answer:
P( -1.96 ≤ Z≤ 1.96) = 0.95
Step-by-step explanation:
Explanation:-
Given that the z -scores -1.96 and 1.96
we have to find P( -1.96 ≤ Z≤ 1.96)
P( -1.96 ≤ Z≤ 1.96) = |A(1.96)+A(-1.96)|
= |A(1.96)+A(-1.96| (∵A(-Z) = A(Z))
= 0.4750+0.4750
= 2×0.4750
= 0.95
The probability lies between -1.96 to 1.96
P( -1.96 ≤ Z≤ 1.96) = 0.95

if x = 2 and y=1 then prove that (x-y)²=x²-2xy+y²
Answers
Answer\Step-by-step explanation:
0≤(x − y)^2 ⟹ 0≤x^2−2xy+y^2
⟹ 2xy≤x^2+y^2
⟹ xy≤ x2+y2\2
⟹ xy≤ x^2+y^2
since the clearly nonnegative real x^2+y^2
clearly satisfies x^2+y^2\2 ≤x^2+y^2.
The proof of the quadratic equation (x-y)²=x²-2xy+y² is given.
What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given:
Quadratic equation
(x-y)²=x²-2xy+y²
To prove the equation:
We substitute the value and see if LHS = RHS.
In the LHS,
LHS = (x-y)²
LHS = (2-1)²
LHS = 1
In the RHS,
RHS = x²-2xy+y²
RHS = 4 - 4 + 1
RHS = 1
LHS = RHS
Therefore, the theorem (x-y)²=x²-2xy+y² is proved.

Michael and Imani go out to eat for lunch.
Part A: If their food and beverages cost $25.30 and there is an 8% meals tax, how much is the bill?
Part B: If Michael and Imani add an 18% tip to the bill, what does their lunch cost in total?
Answers
Answer:
Step-by-step explanation:
part=A
So, we must find out what the total bill cost is such that we begin by multiplying the price with the tax such that $25.30(0.08) = $2.024.
Then we add the tax to the price such that
$25.30+2.024 = $27.32
In the case of adding an 18% tip,
So continuing on from the above post, $27.32 is the total after taxes. Then we add an 18% tip which is
$27.32 (.18) = $4.92..........Then, we add it to the $27.32 to get
$27.32 + $4.92 = $32.24 in total!

Answer:_________

Answers
Answer:
62%
Step-by-step explanation:
I took a fraction and made a decimal which was made into a percentage.
186 ÷ 300 = .62
Check: 62% • 300 = 186
The survey Anna conducted has 62% of students whose favorite color is red.
What is percentage?The percentage is the value per hundredth. Percentages can be converted into decimal form by dividing them by hundred, Percentage can also be represented as a fraction.
Given that 186 out of 300 students Anna surveyed chooses red as their favorite color.
The percentage of students whose favorite color is red is no. of students whose favorite color is red divided by the total no. of students multiplied by hundred which is,
= (186/300)×100.
= 186/3.
= 62%.
