3(8 + 6n) = 6n - 12
equals n = -3.
First, expand. Your problem should look like: 24 + 18n = 6n - 12.
Second, subtract 6n from both sides. Your problem should look like: 24 + 18n - 6n = -12.
Third, simplify 24 + 18n - 6n to 24 + 12n. Your problem should look like: 24 + 12n = -12.
Fourth, subtract 24 from both sides. Your problem should look like: 12n = -12 - 24.
Fifth, simplify -12 - 24 to -36. Your problem should look like: 12n = -36.
Sixth, divide both sides by 12. Your problem should look like: n = -
.
Seventh, simplify
to 3. Your problem should look like: n = -3, which is your answer.
Answer:
29/61
Step-by-step explanation:
okay, first imma simplify the question a little bit.
122 students; 46 chose football; 18 chose tennis; 28girls + xboys chose running.
okay now let's find the number of students who chose running
122 - 46 - 18 = 58
now, I'll find the probability
P(Running) = 58/122 = 29/61

a) cannot be determined.
b) Steel
c)Steel
d)Steel
e) Wooden coaster is slower than Steel, Both of them are normally distributed as median are at the center of the box plot. Steel has a greater variability than wooden as the whisker stretch.There no outliers in the box plot as only whiskers are available.
Step-by-step explanation:
- a)cannot be determined, as it shows only the variability of data.
- a)Picture or a graph only shows the decision of data not data points.
- b)Steel because Median of Steel goes from 60 mph to 100 mph.
- c)Steel because the 1st quartile for wood and steel starts at 50.
- c)Steel goes beyond 50 to 100 mph.
- d)Steel goes 48mph as both wooden and Steel are starting at whiskers.
- d)Steel Whiskers are ending at 100.
- e) Both of the them are normally distributed as median at the center.
- Whiskers are higher for steel as it goes faster then wooden.
- Wooden starts faster then Steel as whiskers dont start fast.
- Wooden is whisker is closer to 50 steel closer to 60.
- There is no outliers as no extreme values.
