Answer:
x - 26 ≥ 73
Step-by-step explanation:
x is the total sum of money earned. To find the answer, you need to subtract 26 from x because that's the amount of her expenses. It also has to be either greater than or equal to 73 because she wants to make at least $73 per day.
Can you give me brainliest please?
1. The absolute value of -4.4 is 4.4
2. The opposite of 4.4 is -4.4
So, Bob's answer is -4.4
1. The opposite of -4.4 is 4.4
2. The absolute value of 4.4 is 4.4
So, Glen's answer is 4.4
Glen's answer is larger than Bob's.
Answer:
The variance for the number of correct answers is 2.8 questions
Step-by-step explanation:
The number of correct answers follows binomial distribution, in which we have:
- n identical and independents events: the 15 questions
- two possibles results that we call success and fail: The answer is correct and the answer is incorrect
- probability p of success and 1-p of fail. Probability 1/4 of get the answer correct and probability of 3/4 of get the answer incorrect. This probabilities are calculated on that way because every question have 4 possible answers and one of which is correct.
So, the variance for a variable x that follows a Binomial distributions is:
V(x)=n*p*(1-p)
Then, the variance for the number of correct answers is:
V(x)=15*(1/4)*(3/4) = 2.8125 ≈ 2.8
Because n is equal to 15, p is equal to 1/4 and (1-p) is equal to 3/4.
Answer:
0.48
0.52
No
Yes
Step-by-step explanation:
Result of experiment :
Point up = 48
Point down = 52
Total number of trials = 100
Recall :
Experimental probability = number of outcomes / number of trials
1.)
P(Landing point up) = 48 / 100 = 0.48
2.)
P(Landing point down) = 52 / 100 = 0.52
3.)
The same result will not occur has the outcomes of trials aren't fixed.
4.) Yes, nearly the same result could occur on the second trial, as the number of possible outcubes are just 2 and the number if trials is high.
