I can’t see the picture the picture is very blurry
Your answer would be the first option: has all sides congruent and all angles congruent.
This is because although this does apply to squares, it can also apply to shapes like a rhombus, as it sits not guarantee that those congruent angles are 90° like they must be for the shape to be a square.
I hope this helps!
So you would do 5*2x +5*-8 +15=-15
Then simplify so it would be 10x + -40 + 15 = -15
Then add -40 and 15 together
Then it would be 10x + -25 = -15
Then add 25 to -25 and -15
So it would be 10x = 10
And then divide 10 from 10 with would be 1 so x = 1
Answer:
The mean of the number of restaurants that failed within a year is 28.38 and the standard deviation is 4.02.
Step-by-step explanation:
For each restaurant, there are only two possible outcomes. Either it fails during the first year, or it does not. The probability of a restaurant failling during the first year is independent of other restaurants. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In the city where she lives, the probability that an independent restaurant will fail in the first year is 43 %.
This means that
66 independent restaurants
This means that
Mean:
Standard deviation:
The mean of the number of restaurants that failed within a year is 28.38 and the standard deviation is 4.02.
Answer:
Step-by-step explanation:
make 2 2/3 into an improper fraction by multiplying 2 by 3 and adding to 2
8/3
8/3 divided by 1/4 is the same as 8/3 multiplied by 4/1 (just 4)
32/3=10 2/3
