The scale factor that was used to create triangle J’K’L’ is 1/3
<h3>How to determine the scale factor?</h3>
From the graph, we have the following highlights:
KL = 3
K'L' = 1
The scale factor (k) from JKL to J'K'L is calculated as:
Scale factor = K'L'/KL
This gives
k = 1/3
Hence, the scale factor that was used to create triangle J’K’L’ is 1/3

Answer:
Option B
Step-by-step explanation:
8 - 2x < 18
Subtract 8 from both sides;
-2x < 10
Divide both sides by -2
x > -5
Answer:
x = 3±√5
Step-by-step explanation:
x² - 6x + 4 = 0
x² - 6x + 9 = -4 + 9
(x - 3)² = 5
x - 3 = ±√5
x = 3±√5
Answer:
0.03 is the probability that for the sample mean IQ score is greater than 103.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100
Standard Deviation, σ = 16
Sample size, n = 100
We are given that the distribution of IQ score is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P( mean IQ score is greater than 103)
P(x > 103)
Calculation the value from standard normal z table, we have,
0.03 is the probability that for the sample mean IQ score is greater than 103.
The first year it decreased by 20%. Multiply the cost of the car by 80% ( 100%-20% = 80%)
24,000 x 0.8 = 19200
After the first year the car was valued at €19,200
Now divide the value after the 2nd year by the value after the first year:
16128 / 1900 = 0.84 * 100 = 84%
The car is 84% of the value.
100 - 84 = 16
The cars value decreased by 16% during the second year.
