A bag contains eight batteries, all of which are the same size and are equally likely to be selected. Each battery is a different brand. If you select two batteries at random, use the counting principle to determine how many points will be in the sample space if the batteries are selected without replacement.
Answer:
7*6*5*4*3 = 7P5 = 2520
Step-by-step explanation:
There will be 56 points in the sample space when two batteries are selected without replacement from the bag.
To determine the number of points in the sample space when selecting two batteries without replacement, we can use the counting principle.
The counting principle states that if there are m ways to do one task and n ways to do another task, then there are m * n ways to do both tasks together.
In this case, the first battery can be selected in 8 ways (since there are 8 batteries in the bag).
After selecting the first battery, there are 7 remaining batteries in the bag. For the second battery, there are 7 ways to select it (one less than the previous selection).
Therefore, the number of points in the sample space is given by multiplying the number of possibilities for the first selection (8) by the number of possibilities for the second selection (7):
8 * 7 = 56
There will be 56 points in the sample space when two batteries are selected without replacement from the bag.

1. A ball is kicked up from a platform 36 feet above the ground. The height of
the ball h(t) above the ground (measured in feet) can be modeled by the
function h (t)
-3t2 + 12t + 36, where t represents the amount of time
(in seconds) since the ball was kicked. How long to the nearest second did it
take the ball to hit the ground?
-
seconds to hit the ground
Answer:6
Step-by-step explanation:
So when the ball hits the ground -3t^2+12t+36 must equal 0
So you can factor a -3 out
-3(t^2-4t-12)=0
Factor -3(t-6)(t+2)=0
T-6=0 t+2=0
T=6 t=Negative 2
And since time can’t be negative the answer is 6

Step-by-step explanation:
Function Modeling
The behavior of some parameters that depend on a set of variables can be modeled in several ways, like linear, quadratic, exponential, logarithmic, among many others.
The selection of the model is often a complex decision that involves statistics and data analysis.
The question provides us with four points where the volume of popcorn bags and the price in dollars. The easiest function that can be used is the line.
The equation of a line of the volume V and the price p can be found with the expression
We'll use the first two values (6,10) (8,20)
Simplifying and rearranging, we get the model
To test the accuracy of the model, we compute the values of p for V=35 and for V=48
Since the computed values are equal to those of the table, the model is accurate. We can now predict the price for V=60
The price for a 60-ounce bag of popcorn would be $16

The Boston Red Sox had 949 runs in their 2004 season. In their 2015 season, they had 748 runs. Find the rate of change in runs.
Answer: -18.27 per year
Step-by-step explanation:
The difference in years is:
= 2015 - 2004
= 11 years
In those 11 years, the runs decreased from 949 to 748.
The total decrease is:
= 949 - 748
= 201 runs
The rate of change is:
= 201 / 11
= 18.27 per year
Since it is reducing, the rate is:
= -18.27 per year

Answer:
(4, 1)
Step-by-step explanation:
8 units to the right = x + 8, so -4 + 8 = 4
4 units up = y + 4, so -3 + 4 = 1
