The answer would be A) he bought 3 games because he only has 22 and 3 times 6 is 18 leaving him a remainder of 4 dollars which he buys the movie with and your second answer is C) the x is next to six because they wanna know how many games he bought not movies
You are looking at around 81.5% i assume by shifting the standard deviation by the same amount on both sides the % will not change
i split the normal distribution curve into 8 pieces
.15 +2.35+13.5+34+34+13.5+2.35+.15 34+34+13.5=81.5%
the ones bolded are the sections that u r dealing with
now the standard deviation is only 4400 so these numbers are going to be skewed off to the right a bit however bcus both sides are skewed evenly i believe they balance each other out
im not completely certain of this but still i hope i helped if so give me a brainliest answer i need a few more to move up a rank -J (:
Proportion: a:b = c:d where ad = bc
a = 1 ; b = 50 ; c = x ; d = 470
1 inches : 50 feet = x inches : 470 feet
1* 470 = 50x
470/50 = x
9.4 = x
The model should be 9.4 inches high.
Answer: the rate of the westbound train is 85 mph.
Step-by-step explanation:
Let x represent the rate of the westbound train. The westbound train travels 10 miles per hour slower than the eastbound train. It means that the rate of the eastbound train is (x + 10) mph.
The two trains leave the station at the same time. The total distance covered by both trains after 3 hours is 540 miles.
Distance = speed × time
Distance covered by the westbound train in 3 hours is 3x.
Distance covered by the eastbound train in 3 hours is 3(x + 10)
Therefore,
3x + 3(x + 10) = 540
3x + 3x + 30 = 540
6x = 540 - 30 = 510
x = 510/6 = 85 mph
