Answer:
Carmen's prediction is low because 200 times is 50.
Step-by-step explanation:
First of all we are going to define the sample space for this exercise.
The sample space is Ω = {1,2,3,4,5,6,7,8}
Given the event A : ''Roll an 8-sided die an get a multiple of 4''
The probability for the event A is
Because they are two numbers (4 and 8) over a total of eight numbers (1,2,3,4,5,6,7,8) that are multiple of 4.
Now, given the random variable X : ''Total of numbers multiples of 4 If she rolls
an 8-sided die 200 times''
X can be modeled as a Binomial random variable.
X ~ Bi (n,p)
X ~ Bi (200,)
In which n is the total times she rolls the 8-sided die and p is the success probability.We define a success as obtain a number multiple of 4.
The mean for this variable is
We answer that Carmen's prediction is low because 200 times is 50.
Answer:
AB = 5 units
BC = 5 units
AC = or about 6.4 units
Step-by-step explanation:
distance formula: square root of the sum of the difference of the y-values and the difference of the x-values
ex, dAB = √(4-0)² + (3-0)²
= √16 + 9
= √25
= 5

<h3>Answer:</h3>3 from the numerator was multiplied six times, and 3 from the denominator is multiplied 4 times. The small number at the top right (which is the exponent) of the 3 is how much the number is repeated.
