From the given data we shall obtain the following boxplot, which we can generate the information given:
<span>5.5, 5.7, 5.8, 6.0, 6.1, 6.1, 6.3, 6.4, 6.5, 6.6, 6.7, 6.7, 6.7, 6.9, 7.0, 7.0, 7.0, 7.1, 7.2, 7.2, 7.4, 7.5, 7.7, 7.7, 7.8, 8.0, 8.1, 8.1, 8.3, 8.7
1st Qu=6.425
3rd Qu=7.650

Answer:
Explanation:
49-20=29 blue counters
There’s a 29/49 chance that the counter will be blue
1.3 x 0.4 x 2 = 1.04
0.5 x 0.4 = 0.2
(
(0.5 x 1.2)) x 2 = 0.6
1.04 + 0.2 + 0.6 = 1.84m²
Step-by-step explanation:
Let A be the set of people who speak English.
B be the set of people who speak French.
A - B be the set of people who speak English and not French.
B - A be the set of people who speak French and not English.
A ∩ B be the set of people who speak both French and English.
Given
n(A) = 72 n(B) = 43 n(A ∪ B) = 100
Now, n(A ∩ B) = n(A) + n(B) - n(A ∪ B)
= 72 + 43 - 100
= 72 + 43 - 100
= 115 - 100
= 15
Therefore, Number of persons who speak both French and English
= 15
n(A) = n(A - B) + n(A ∩ B)
⇒ n(A - B) = n(A) - n(A ∩ B)
= 72 - 15
= 57
and n(B - A) = n(B) - n(A ∩ B)
= 43 - 15 = 28
Therefore, Number of people speaking English only = 57
Number of people speaking French only = 28
Answer:
14
Step-by-step explanation:
5x-7=3x+21
2x=28
x=14
