Answer:
x=50
Step-by-step explanation:
The answer is 0.5
Just take one point from the original shape and one from the transformed one. The just write the ordered pair out. Mine was (3,4) and (1.5, 2) Now in order for you to get from 3 to 1.5 you need to multiply 0.5 so the scale factor that was used is 0.5

Answer:
Option b is correct
Step-by-step explanation:
In order to check the end behavior of a polynomial function we just check the leading term and its coefficient and the procedure is as follows:
Here we can see that highest exponent of the polynomial function is 4
therefore degree of the polynomial is 4. and therefore is leading term.
because of even degree it will be same from both ends that is either both sides rises or both sides falls. Since number in the front of leading is negative therefore it falls at both ends. that is falls to the left and falls to the right.
therefore option b is correct.
Answer:
a) 4.60 (2 dp)
b) 1.31 (2 dp)
c) 8.8
Step-by-step explanation:
The "Frequency" part of a frequency table is the measure of how often the data value occurs.
To calculate the mean of data presented in a frequency table, we need to multiply each data value by its given frequency, sum these, then divide by the sum of the frequency.
The formula for mean is:
<h3><u>Part (a)</u></h3>
Add a row showing the values of
Add a column showing the totals of and
Now use the formula to calculate the mean:
<h3><u>Part (b)</u></h3>
Add a column showing the values of
Add a row showing the totals of and
Now use the formula to calculate the mean:
<h3><u>Part (c)</u></h3>
Add a column showing the values of
Add a row showing the totals of and
Now use the formula to calculate the mean:
