The answer is 20
Step-by-step explanation:
what is double of 10
20
10 times 2 equals 20
Probability of distinct 3-digits is 1/6.
Probability of both the first digit and the last digit are even numbers is 1/5.
<u>Step-by-step explanation</u>:
Given set of numbers {1,2,3,5,8,9} = 6
Total number of 3-digits can be formed = 654 = 120.
<u>Probability of the three-digit numbers with distinct digits</u> :
The number of 3-digit numbers with distinct digits = (654) / (321) = 20.
P(distinct 3-digits) = no. of distinct 3-digits / Total no.of 3-digits
⇒ 20/120
⇒ 1/6
<u>Probability that both the first digit and the last digit of the three-digit number are even numbers</u> :
The even numbers in the set are 2 and 8 = 2 possibilities.
The number of 3-digits with 1st and 3rd digit are even = (262) = 24.
P(1st and 3rd digits even)= no. of 1st and 3rd digit even/Total no. of 3-digits.
⇒ 24/120
⇒ 1/5
Mean is also another way of saying average.
so first you need to add all the numbers together. then divide by 6 because you added 6 different numbers together. then you should get 87
90+100+48+88+100+96=522
522÷6=87
Answer:
Statement Reason
∆ABC and ∆ADC are isosceles Given
Segment AC is a common base
to ∆ABC and ∆ADC Given
Let K be the midpoint of the base
of segment AC, then BK is the
perpendicular bisector of segment perpendicular bisector of isosceles AC. triangle property.
Also, DK is the perpendicular
bisector of segment AC. perpendicular bisector of isosceles
triangle property
X + 5000= 187000 (let the number be x since its unknown)
x = 187000-5000 (take 5000 to the right side to get x on its own)
x = 182000
