Answer:
BC = 3.6
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
1.5 BC = 5.4 ( divide both sides by 1.5 )
BC = 3.6
Answer:
How to Conduct a Simulation
Describe the possible outcomes.
Link each outcome to one or more random numbers.
Choose a source of random numbers.
Choose a random number.
Based on the random number, note the "simulated" outcome.
Repeat steps 4 and 5 multiple times; preferably, until the outcomes show a stable pattern
Answer:
If the null hypothesis is true in a chi-square test, discrepancies between observed and expected frequencies will tend to be small enough to qualify as a common outcome.
Step-by-step explanation:
Here in this question, we want to state what will happen if the null hypothesis is true in a chi-square test.
If the null hypothesis is true in a chi-square test, discrepancies between observed and expected frequencies will tend to be small enough to qualify as a common outcome.
This is because at a higher level of discrepancies, there will be a strong evidence against the null. This means that it will be rare to find discrepancies if null was true.
In the question however, since the null is true, the discrepancies we will be expecting will thus be small and common.
X/3 > 7 <== ur equation
multiply both sides by 3
x > 7 * 3
x > 21 <== ur solution
Answer:
A, D
Step-by-step explanation:
When we multiply the fractions, we can get:
This is also equivalent to:
When looking at the answer choices, the only ones that equal are A and D because:
