For this case we have the following ordered pairs:
(6, 9)
(4, 6)
The scale factor can be found in two different ways:

Therefore, the scale factor is given by:
Answer:
The scale factor of the dilation is 1.5
Answer:
D
Step-by-step explanation:
Mean tells us the average (in this case, total marks/ total number of students).
Standard deviation tells us the spread of a set of data from its mean (how much it deviates from the mean).
Thus, standard deviation can be used to determine the consistency of a data. <u>The smaller the standard deviation, the more consistent the data is</u>.
Since 4S has the smallest standard deviation of 1, it shows the most consistent achievement in the test.
To make the equations you must first get the percents and make them into a decimal. then multiply the money by the decimal
EX: $230.76 with a profit of 30%
First make the percent a decimal to do so move the . over to the left two times resulting in the number .30
so the equation is 230.76(.30)
which equals 69.228
now simplify it making the answer $69.23
now to get the store price, add manufacture price with the %30 of the the MP resulting in the answer
$299.99
Answer:
D
Step-by-step explanation:
7.3 ------ 8.1 8.5 8.9
let us try to find the common difference here using last three terms
8.5-8.1=0.4
8.9-8.5=0.4
so it is clear that common difference is 0.4
so adding 0.4 to 7.3 will give the next term
7.3+0.4=7.7
Answer : missing number is 7.7
