Answer:

$- 2\frac{1}{2}$ inches

Step-by-step explanation:

The water level at Lake Penny changed $- 1\frac{1}{10} = - 1.1$ inches

Again, in the next year, it is predicted to change another $- 1\frac{2}{5} = - 1.4$ inches

Therefore, the total change that will likely occur in 2 years is (- 1.1 - 1.4 ) = - 2.5 inches = $- 2\frac{1}{2}$ inches. (Answer)

Jodie Meeks's Free Throws During the 2015-16 NBA season, Jodie Meeks of the Detroit Pistons had a free throw shooting percentage

Damm [24]

Answer:

0.8973

Step-by-step explanation:

Relevant data provided in the question as per the question below:

Free throw shooting percentage = 0.906

Free throws = 6

At least = 5

Based on the above information, the probability is

Let us assume the X signifies the number of free throws

So, Then X ≈ Bin (n = 6, p = 0.906)

$P = (X = x) = $\sum\limits_{x}^6 (0.906)^x (1 - 0.906)^{6-x}, x = 0,1,2,3,.., 6$

Now

The Required probability = P(X ≥ 5) = P(X = 5) + P(X = 6)

$= $\sum\limits_{5}^6 (0.906)^5 (1 - 0.906)^{6-5} + $\sum\limits_{6}^6 (0.906)^6 (1 - 0.906)^{6-6}$

= 0.8973

Reuben drove 268 miles using 12 gallons of gas. At this rate, how many miles would he drive using 9 gallons of gas?

Sav [38]

This question calls for ratios. Reuben drove 268 miles with 12 gallons. 268 divided by 12 is $22\frac{1}{3}$ , so he can drive 22 and one third of a mile with one gallon. Multiply that by 9 and you will get 201 miles, which is how much he can drive using 9 gallons of gas

What’s the axis of symmetry and the vertex of x^2-4x-32

konstantin123 [22]

<span>x^2 -4x -32
</span>a =1b= -4c= -32
The x,y points of the vertex are usually referred to as Vertex = (h, k)where h = -b / (2 * a)
h = --4 / (2 * 1)h = 4 / 2h = 2
k = ah^2 +bh + ck =1*4 -4*2 -32k = 4 -8 -32k = -36
vertex = (2, -36)axis of symmetry = x position = 2
