Answer:
? = 9
Step-by-step explanation:
The segments of each of the transversals are proportional. On the left side, the bottom transversal segment will be 10 -6 = 4 units in length.
Now we can write a proportion relating right-side transversal segments to left-side transversal segments:
?/6 = 6/4
? = 6(6/4) = 36/4 = 9
The missing length is 9 units.
The relative frequency with which the coin will land on tails 12 of those times willl be 48%. None of the given options are correct.
<h3>What is the formula for calculating the joint relative frequency?</h3>
Assume you need to compute the joint relative frequency of a certain category inside a larger category. Then there's the proportion of that specific category's frequency to the total frequency of that large category.
If the experiment is run 25 times and we receive tails 12 times, the relative frequency of receiving tails is as follows:
Hence, the relative frequency for the given condition will be 48%.

In order to use the remainder theorem, you need to have some idea what to divide by. The rational root theorem tells you rational roots will be from the list derived from the factors of the constant term, {±1, ±5}. When we compare coefficients of odd power terms to those of even power terms, we find their sums are equal, which means -1 is a root and (x +1) is a factor.
Dividing that from the cubic, we get a quotient of x² +6x +5 (and a remainder of zero). We recognize that 6 is the sum of the factors 1 and 5 of the constant term 5, so the factorization is
... = (x +1)(x +1)(x +5)
... = (x +1)²(x +5)

The product of factors (x +a)(x +b) will be x² + (a+b)x + ab. That is, the factorization can be found by looking for factors of the constant term (ab) that add to give the coefficient of the linear term (a+b). The numbers found can be put directly into the binomial factors to make (x+a)(x+b).
When we have 1·5 = 5 and 1+5 = 6, we know the factorization of x²+6x+5 is (x+1)(x+5).
Answer:
Here’s how you find the mean. Find the sum of all the data combined. Then divide the sum by how many numbers of data there are!!
