Answer:
Gay.
Step-by-step explanation:
I means gay, some people just refer to that but most commonly known as 'gay'.
B. Fail to reject the null hypothesis.
C. Reject the null hypothesis and conclude the mean is lower than $6,000 per day.
D. Reject the null hypothesis and conclude the mean is higher than $6,000 per day.
Answer:
Option B) Fail to reject the null hypothesis.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $6,000
Sample mean, = $6,300
Sample size, n = 49
Alpha, α = 0.01
Population standard deviation, σ = $1,000
First, we design the null and the alternate hypothesis
We use one-tailed(right) z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We fail to reject the null hypothesis and accept the null hypothesis. Thus, we conclude that sales have not increased as a result of the advertising campaign
Option B) Fail to reject the null hypothesis.
7 x 3/4
The equivalent value of the expression is A = 21/4
Given data:
The first number is represented as a = 7
The second fraction is represented as b = 3/4
So, the equation is A = ab
And, A = 7 x 3/4
So, 7 multiplied by 3/4 equals 21/4.
However, to express the answer in its simplest form, we can simplify the fraction by dividing both the numerator and denominator by their greatest common factor.
The greatest common factor of 21 and 4 is 1, so we divide both numerator and denominator by 1.
Hence, the simplest form of the equation is A = 21/4

B.) 2n
C.) n²
All of the following expressions represent the sum of n and itself, except n² so option (C) will be correct.
An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.
In other meaning, expression is very useful to determine the end or root value of constraint.
For example 3x +5y
The constraint of expression is represented as = or <, >.
The expression n + n is the sum of n and n(itself).
The expression 2n = n + n is the sum of n and n(itself).
The expression n² = n × n is the multiplication of two n, not a sum so it will not sum of n and itself.
Hence "All of the following expressions represent the sum of n and itself, except n²".
