Mutually exclusive means that the intersection of the events is empty: P(S and T) = 0.
P(S or T) = P(S) + P(T) = 29% + 49% = 78%
If events S, T are not mutually exclusive, then P(S or T) = P(S) + P(T) - P(S and T)
Answer:
2 more plants did
Step-by-step explanation:
9, 12, 11, 8, 7, 9, 12, 12, 9, 11, 8, 9
9,8,7,9,9,8,9 Are the plants that are less then ten inches and there are 7
of them
12,11,12,12,11 Are the plants that are more than 10 inches tall and there are five.
2 more grew less than ten inches than they did 5 inches.
The true statements are :
the average monthly temperatures of New Orleans are not as varied as that of Indianapolis.
The median of the average monthly temperatures of New Orleans is equal to the upper quartile of the average monthly temperature of Indianapolis.
<h3>What are the true options?</h3>
A box plot is used to study the distribution and level of a set of scores. The box plot consists whiskers. The whiskers represents the minimum and maximum scores.
On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.
Range for New Orleans = 85 - 50 = 35
Range for Indianapolis = 75 - 25 = 50
Median for New Orleans = 70
Upper quartile for Indianapolis = 70

Let's do the bracket part first,
and solve further as shown,
Answer:
the speed s=65 mph
distance to reach d=26 miles
what is time required to reach 26 miles with a speed of 65mph , t?
distance =speed x time
time= d/s
t=26/65=0.4hrs=24minutes would be the answer
