1) Mean= Sum of total Observation/ Total no.of observation
Mean= 42/6=7
option (b) 7


2)To calculate Median first arrange the numbers in a numerically ascending order.

Since, there are even no.of total Observation median will be the mean of two middlemost terms.

3,6,7,9,9,10

Middle terms are 7 and 9
Median= 7+9/2= 8

option(c) 8

Question 18
Svetlanka [38]

Answer:

Step-by-step explanation:

J and K are equal

8x - 23 = 6x + 11            Add 23 to both sides

8x = 6x + 11 + 23           Combine the right

8x = 6x + 34                  Subtract 6x from both sides

8x - 6x = 34                   Combine the left

2x = 34                           Divide by 2

x = 34/2

x = 17

=================================

M and L are both supplementary to J and K respectively.

J = 8x - 23

J = 8*17 - 23

J = 136-23

J = 113

K = 113

===================================

M + 113 = 180

M = 180 - 113

M = 67

L = 67

Area of Park = Length * Width

Therefore Width = Area / Length

= (6/8) / (1/2) = (6/8) * (2/1) = 3/2 miles.

Given the data shown below, which of the following is the best prediction for the number of years it will take for the populatio
aleksley [76]

We will have the following:

Using exponential regression we will have that the line of best fit will be:

f\mleft(x\mright)=8585.658603*1.399211892^x

Now, we will have that:

\begin{gathered} 300000=8585.658603*1.399211892^x\Rightarrow34.94199034=1.399211892^x \\  \\ \Rightarrow x=\frac{ln(34.94199034)}{1.399211892}\Rightarrow x= \end{gathered}

So, the approximation using linear regression gives us as solution approximately 29.7 years; thus the closest one to match is then

State weather the equation represents exponential growth, exponential decay or neither, 30 POINTS EASY
RSB [31]

Answer:

Exponential Decay

Step-by-step explanation:

It's exponential growth when your base value is > 1. Example:

1.3ˣ, 2ˣ, 7ˣ, 999ˣ

It's exponential decay when the base value is < 1. Example:

0.9ˣ, 0.45ˣ, (1/2)ˣ, 0.79ˣ, .999ˣ

It's neither when the base value = 1. Example:

1ˣ
