Answer:
The answer is yes.
Step-by-step explanation:
To test if the null hypothesis, in this case the wheel being rigged, we need to perform a number of tests and find the p value. If the p value is above a certain level, then it is statistically significant and we can say that the null hypothesis is correct.
It is stated that the standard rate of getting a red number is 0.47, which is 47%. Out of 400, to get a 47% rate, we would need to have red 188 times which is less than 196 so the test results in a rate above 47% in which case the null hypothesis is correct and we can say that the wheel is rigged.
I hope this answer helps.
Answer:
$0.85
Step-by-step explanation:
2 juice pouches- $2.50
3c+2.50=5.05 (c is for bags of chips)
3c=5.05-2.50
3c=2.55
c= $0.85
So one bag of chip is $0.85
Answer:
The quadratic equation is x^2-2x-4
Step-by-step explanation:
We want to know the equation that has the solution below;
x = 1 ± √5
This means x = 1 + √5 or 1 - √5
The equation would thus be;
(x-1-√5)(x-1+ √5)
= x(x-1+ √5)-1(x-1+ √5)-√5(x-1+ √5)
Opening the brackets we have ;
x^2-x+ √5x-x + 1 -√5-√5x+ √5-5
collecting like terms we have;
x^2-2x+1-5
= x^2-2x-4
Answer:
Well, I don't think I can remember EVERY skill I was taught through the years but in Kindergarten we used Number Sense so we could accurately... also there's estimation and of course PEMDAS. I've also learned how to round up so that the solution is at least around those numbers if the skill is to be applied.

I'm not sure if this'll help but go ahead and have it... just try and change it a bit so they don't get ya for plagirism
