She bought 8 bags of candy with 10 pieces in each one.
Answer:
a) 0.6667 = 66.67% probability that the temperature will be above 80°F.
b) 0.3333 = 33.33% probability that the temperature will be between 80°F and 85°F.
c) The expected temperature is of 82.5ºF.
Step-by-step explanation:
Uniform distribution:
The probability of all outcomes between a and b is the same.
Uniform distribution over the interval from 75°F to 90°F.
This means that
a. What is the probability that the temperature will be above 80°F?
We have that, on the uniform distribution:
In this question:
0.6667 = 66.67% probability that the temperature will be above 80°F.
b. What is the probability that the temperature will be between 80°F and 85°F?
We have that:
Then, in this question:
0.3333 = 33.33% probability that the temperature will be between 80°F and 85°F.
c. What is the expected temperature?
The expected value of the uniform distribution is:
In this question:
The expected temperature is of 82.5ºF.
Answer:
I dont know uhm i think no sorry if im wrong
Step-by-step explanation:
Answer:
The Two Consecutive integers are 7 and 8.
Step-by-step explanation:
Let the first Integer be x
Since the two numbers are consecutive
therefore the second number will be x+1
Now given:
the square of the second integer added to 3 times the first is equal to 85
Hence framing the above sentence in mathematical form we get;
Now Solving the above equation we get;
since
Using addition property we get;
Using Subtraction property we get;
Now factorizing above equation we get;
Now we get 2 values of x which is 7 and -12.
Since it is given that number is positive Integer hence the number will be 7
and the other number would 7 + 1 = 8.
