Among 806 people asked which is there favorite seat on a plane, 492 chose the window seat, 8 chose the middle seat, and 306 chose the aisle seat, then

a) One randomly selected person preferes aisle seat with probability

b) Two randomly selected people both prefer aisle seat (with replacement) is

c) Two randomly selected people both prefer aisle seat (without replacement) is

Round to the nearest thousands
8,276 = 8,000
2,451 = 2,000
8,000 + 2,000 = 10,000
answer

5 students scored a 90 or above. If you look at the axis that says “test scores” just count the number of dots on the “90” line and above
Answer:
x=260 texts
Step-by-step explanation:
85=0.25x+20
Subtract 20 from each side.
65=0.25x
Divide both sides by 0.25.
260=x
260 texts plus the $20 flat fee will cost $85.
Answer:
sum of the series = 7182
Step-by-step explanation:
This is an arithmetic series. The first term is known as 586 and the last term is known as 212. We are ask to find the sum of the series. The common difference of this sequence is -22 . The difference between the next term and the previous term is -22. Let us find the number of terms.
common difference = 564 - 586 = -22
number of terms = n
nth term = a + (n - 1)d
212 = 586 + (n - 1)-22
212 = 586 - 22n + 22
212 - 586 - 22 = -22n
-396 = -22n
divide both sides by -22
n = -396/-22
n = 18
Using the formula for sum
sum of nth term = n/2(a + l)
where
l = last term
a = first term
n = number of term
sum of nth term = n/2(a + l)
sum of nth term = 18/2(586 + 212)
sum of nth term = 9(798
)
sum of the series = 7182
