Consider the relation. {(–3, 2), (–1, 3), (–1, 2), (0, 4), (1, 1)} Determine which best describes the given relation. The given relation is not a function because the input of –1 has two outputs of 2 and 3. The given relation is a function because the input of –1 has two outputs of 2 and 3.

The table below shows the distance d(t) in feet that an object travels in t seconds: t (seconds) d(t) (feet) 2 64 4 256 6 576 8 1024 What is the average rate of change of d(t) between 2 seconds and 6 seconds, and what does it represent? 128 ft/s; it represents the average speed of the object between 2 seconds and 6 seconds 80 ft/s; it represents the average speed of the object between 2 seconds and 6 seconds 128 ft/s; it represents the average distance traveled by the object between 2 seconds and 6 seconds 80 ft/s; it represents the average distance traveled by the object between 2 seconds and 6 seconds

Answers

Answer:

128 ft/s; it represents the average speed of the object between 2 seconds and 6 seconds

Step-by-step explanation:

The average rate of change is another way to say slope.

slope = (y2-y1)/(x2-x1)

      = (576-64)/(6-2)

      = (512/4)

     =128 ft/s


This represents the change in ft per second, or the  average speed the object is going during the time period.

What is the difference between (-58) and (+35) ?

Answers

To do this question, you are best splitting it into two halves: getting to 0, and then 35
Starting at -58, we want to get to 0
-58 + 58 = 0
Then, we get to 35 from 0
0 + 35 = 35
Now, add the two values together
58 + 35 = 93
The difference is 93
If the equation is -58-35, the answer would be -93. It would be -93 because you would KEEP THE SIGN OF THE BIGGER NUMBER (Whether it's - or +) IF THE SIGN IS THE SAME YOU ADD (If the sign is - and - or + and +) IF THE SIGN IS DIFFERENT YOU SUBTRACT (So that means if you have + and - or - and +).

On the first of each month, Stacie runs a 5k race. She keeps track of her times to track her progress. Her time in minutes is recorded in the table: Jan 41.55 July 36.38 Feb 42.51 Aug 38.48 Mar 43.01 Sept 41.87 Apr 39.76 Oct 51.32 May 37.32 Nov 42.59 June 35.28 Dec 43.71 Determine the difference between the mean of the data, including the outlier and excluding the outlier. Round to the hundredths place. 1.21 0.93 40.98 40.22

Answers

The difference between mean with outlier and mean without outlier is 0.93

Step-by-step explanation:

Total months are 12

So,

n=12

Sum of all values = 493.78

The mean is given by:

Mean=(Sum\ of\ values)/(No.\ of\ values)\n=(493.78)/(12)\n=41.148\ minutes

The mean with outlier is: 41.148

Now to calculate the mean without outlier

We will subtract the outlier value from total sum

The outlier is 51.32 so the new sum will be: 493.78-51.32 =442.46

Total number of values = 12-1 = 11

The mean without outlier will be:

Mean\ without\ outlier=(442.46)/(11) =40.223

Now the difference between both means is:

41.148-40.223=0.925 => 0.93

The difference between mean with outlier and mean without outlier is 0.93

Juanita organizes her magazines into 3 equal piles. She has a total of 18 magazines. How many magazines are in each pile

Answers

The number of magazines in each pile will be 6.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Juanita organizes her magazines into 3 equal piles. She has a total of 18 magazines.

The number of magazines in each pile will be calculated as,

N = 18 / 3

N = 6 piles

Therefore, the number of magazines in each pile will be 6.
