Out of 50 rolls of a standard number cube, 25 rolls will result in an odd number.
Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?
A standard number cube has 6 faces, numbered 1 through 6. Out of these, there are three odd numbers: 1, 3, and 5.
Since there are three odd numbers out of a total of six possible outcomes, the experimental probability of rolling an odd number on a standard number cube is:
Experimental probability = Number of odd outcomes / Total number of outcomes
Experimental probability = 3/6
Experimental probability = 1/2 or 0.5
This means that in the longrun, we can expect half of the rolls of a standard number cube to result in an odd number.
To predict the number of rolls that will result in an odd number out of 50 rolls, we can simply multiply the total number of rolls by the experimental probability:
Number of rolls resulting in an odd number = Total number of rolls x Experimental probability
Number of rolls resulting in an odd number = 50 x 0.5
Number of rolls resulting in an odd number = 25
Therefore, we can predict that out of 50 rolls of a standard number cube, 25 rolls will result in an odd number.

Answer:
The lens is 1 inch from the mirror
Step-by-step explanation:
* Lets revise the equation of the hyperbola with center (0 , 0) and
transverse axis parallel to the y-axis is y²/a² - x²/b² = 1
- The coordinates of the vertices are (0 , ± a)
- The coordinates of the co-vertices are (± b , 0)
- The coordinates of the foci are (0 , ± c) where c² = a² + b²
* Lets solve the problem
∵ The equation of the hyperbola is y²/16 - x²/9 = 1
∵ The form of the equation is y²/a² - x²/b² = 1
∴ a² = 16
∴ a = √16 = 4
∵ The coordinates of the vertices are (0 , ± a)
∴ The coordinates of the vertices are (0 , 4) , (0 , -4)
∴ b² = 9
∴ b = √9 = 3
∵ c² = a² + b²
∴ c² = 16 + 9 = 25
∴ c = √25 = 5
∵ The coordinates of the foci are (0 , ± c)
∴ The coordinates of the foci are (0 , 5) , (0 , -5)
∵ The camera is pointed towards the vertex of the hyperbolic mirror
which is (0 , 4) and is positioned such that the lens is at the nearest
focus to that vertex which is (0 , 5)
∴ The distance between the lens and the mirror equal the distance
between the vertex and the focus
∵ The vertex is (0 , 4) and the nearest focus is (0 , 5)
∴ The distance = 5 - 4 = 1 inch
* The lens is 1 inch from the mirror

Step-by-step explanation:
Answer:
Options B,C and E are correct choices.
Step-by-step explanation:
We are asked to find correct answers for the given box and whisker plots.
Let us our options one by one.
A. This option is false as lowest value for children's cereals is 30 and highest value for adults is 35.
B. This option is correct. We can see our upper value for combined range will be 60 and lower value will be 5 and range is upper value- lower value.
C. Since we know that we can find spread of data by its range.
So option C is correct indeed.
D. This options is false because for adults mean and median are different while for children mean and median are same.
E. We can see that median for children's cereals is 45 and it is about 12 for adults.
We can see that . So median amount of sugar in children's cereals is 3 times as much as the median amount of sugar in adult's cereals.
Therefore, options B,C and E are correct choices.
