To answer this question, use permutation since the order of the letter matters. There are 7 letters and only 4 are to be used for the code. This is a permutation of 7 taken 4 (7P4) which is equal to 840. Thus, the sample space is 840.
For the next questions, there are 3 vowels for as the first letter, only 6 letters are available for the second, 5 on the next, and 4 on the last. Multiplying these numbers give 360. To solve for probability, divide this number with the sample space. Thus, the answer is 3/7.
Answer: True
Step-by-step explanation:
Answer:
Most Unlikely: Less than 5
Likely: 2-digit number
Unlikely: Multiple of 3
Equally Likely: Odd
Most Likely: Greater than 10
Step-by-step explanation:
there are 6x5, or 30 outcomes
Less than 5 has 1 outcome - spinner and dice both are one
Odd has 15 outcomes
Multiple of 3 has 8 outcomes: 1+5, 2+1, 2+7, 2+12, 3+12, 4+5, 5+7, 5+10
Two-digits has 12 outcomes
Greater than ten has 16 outcomes
Answer:
Arc EC = 58°
Step-by-step explanation:
First, find the value of x.
m<D = ½(arc EC) => Inscribed Angles Theorem
Substitute
2x - 5 = ½(5x - 27)
Multiply both sides by 2
2(2x - 5) = 5x - 27
4x - 10 = 5x - 27
Collect like terms
4x - 5x = 10 - 27
-x = -17
Divide both sides by -1
x = 17
Find arc EC:
Arc EC = 5x - 27
Plug in the value of x
Arc EC = 5(17) - 27 = 85 - 27
Arc EC = 58°
The question says:
2×2+2÷2
so first you should find 2 × 2 which is 4 and then 2 ÷ 2 which is 1
now you have:
4 +1 = 5 so the answer is 5 :)))
i hope this is helpful
have a nice day
