Answer:

You need to pay attention to the column for if they like school and the column for whether or not they have siblings. There are 11 who like school and 3 who do not like school. Then there are 9 who have siblings and 5 who do not have siblings. In comparing those that like school with those that have siblings you have 8 who like school and who have siblings, 3 who like school and who do not have siblings, 1 who does not like school and has a sibling and 2 who do not like school and who do not have siblings. The correct table is

The growth of 100 young trees near a river is given below. At most 50 yards from the river (Event Y) More than 50 yards from the

Alona [7]

Answer:

It is 91% more likely that the tree was atmost 500 yards from the river.

<h3>Step-by-step explanation:</h3>

We are given with distance and height of 100 young trees near a river.

From that table, in total there are 55 trees which grow more than 3 ft during the year.

And among those 55 trees, 50 trees are atmost 50 yards from river.

Hence it is ≈91% more likely that the tree was atmost 50 yards from the river.

If the interval (a, ∞) describes all values of x for which the graph of 4/x^2-6x+9 is decreasing, what is the value of a?

harkovskaia [24]

Answer:

a = - 1.1

Step-by-step explanation:

Condition for a single variable function f(x) to be decreasing is f'(x) < 0.

So, in our case, $f(x) = \frac{4}{x^{2}} - 6x + 9$ .

Then, differentiating with respect to x on both sides we get,

$f'(x) = 4(- 2)\frac{1}{x^{3}} - 6 < 0$

⇒ $- \frac{8}{x^{3}} - 6 < 0$

⇒ $\frac{8}{x^{3}} + 6 > 0$

{Dividing both sides with - 1 and hence the inequality sign changes}

⇒ $\frac{8}{x^{3}} > - 6$

⇒ 8 > - 6x³ {Multiplying both sides with x³}

⇒ 6x³ > - 8 {Interchanging the sides}

⇒ $x^{3} > - \frac{8}{6}$

⇒ x > - 1.1

Therefore, a = - 1.1. (Answer)
