Answer:
In directing any measurable investigation (right now for mean, for example channeling t-test for mean) the most significant suspicions are as per the following:
The typicality of populace about which ends are being drawn. This implies the populace from which the example has been drawn ought to be at any rate roughly ordinarily circulated. This is a significant supposition and whenever damaged , the test can't be directed by any stretch of the imagination. This supposition may or may not be valid right now. In this way any further test or calculation of certainty interim for mean, would have neither rhyme nor reason.
Furthermore, the conduction of this t test for development of certainty interim additionally doesn't work if there is any exceptions present in the example. There can be an extremely youthful President or an old as well, yet his age will be an anomaly.
In this way, the end dependent on Joe's examination may be deceiving.
Answer:
I'm not so sure on these answers
1) 60 combinations
2) 90 or 60 combinations
Step-by-step explanation:
When doing these types of questions, use the Fundamental Counting Principle (you could also use a tree diagram which lists every possible combination individually for each item)
Basically for Fundamental Counting Principle, you multiply the amounts.
Ex: 5 jeans x 4 T-Shirts = 20 5 x 4 x 3 = 60!
20 x 3 pairs of shoes= 60
I wasn't sure if I had to include the right, left, right as 2 or 3.
Answer:
21
Step-by-step explanation:
We need to utilise one important angle in order to answer this question which is
→ Angles in a triangle add up to 180°
Using this information we can set up an equation to find the value of x
⇒ Form equation using the important angle fact
→ x - 4 + 3x + 100 = 180
⇒ Simplify the 'x' and the numerical terms
→ 4x + 96 = 180
⇒ Minus 96 from both sides to isolate 4x
→ 4x = 84
⇒ Divide both sides by 4 to isolate x
→ x = 21
The value of x is 21
Answer:
22 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 3600° , then
180° (n - 2) = 3600° ( divide both sides by 180° )
n - 2 = 20 ( add 2 to both sides )
n = 22
