Well it would equal 0.55 because 5.50-10%=5.50
In statistics, a Chi-squared test may be used to determine holiday choice and gender and α (alpha) is the response variable.
<h3>What is the Chi-squared test? </h3>
A statistical technique called the chi-square test is used to compare actual outcomes with predictions.
The goal of this test is to establish if a discrepancy between actual and predicted data is the result of chance or a correlation between the variables you are researching.
Whether there is a statistically significant association between categorical variables is determined by the Chi-square test of independence.
This issue is addressed by a hypothesis test. The chi-square test of association is another name for this assessment.
Hence,in stats would a test looking at gender & holiday preference yes you can do a Chi-squared test and α(alpha) is the response variable.

Answer:
y = -30
Option A
Step-by-step explanation:
y = -2x - 10
y = -5x + 20
We just need to substitute the values of y.
We have to equate both the equation.
-2x -10 = -5x + 20
-2x + 5x = 20 + 10
3x = 30
x = 10
Plug x as 10 in any one of the equation
Let's take the first equation
y = -2x - 10
y = -2(10) - 10
y = -20 -10
y = -30
Answer: 1/12 of total pizza
Step-by-step explanation:
Mrs. Johnson first cut the pizza into equal sections of three.
This means that each section is 1/3 of the total pizza.
She then gave 1 section to her four children to share.
Each child will therefore get:
= 1/3 ÷ 4 children
= 1/3 * 1/4
= 1/12 of the total pizza
<em>Hint: When dividing a fraction by a number, you can instead multiply that fraction by the inverse of that number.</em>
