Answer:9282
Step-by-step explanation:
Answer:
x ≈ 0.693
Step-by-step explanation:
Using the rule of logarithms
log ⇔ n log x and lne = 1
Given
2 = 4 ( divide both sides by 2 )
= 2 ( take the ln of both sides )
ln = ln2, that is
x lne = ln2, thus
x = ln2 ≈ 0.693 ( to 3 dec. places )

area of a triangle: a=1/2bh
a= (1/2)(5)(10)
a=25
Answer:
59 accidents were investigated.
Step-by-step explanation:
The question above is a probability question that involves 2 elements: causes of accidents.
Let
A = Alcohol
E = Excessive speed
In the question, we are given the following information:
18 accidents involved Alcohol and Excessive speed =P(A ∩ E)
26 involved Alcohol = P(A)
12 accidents involved excessive speed but not alcohol = P( E ) Only
21 accidents involved neither alcohol nor excessive speed = neither A U B
We were given P(A) in the question. P(A Only) = P(A) - P(A ∩ E)
P(A Only) = 26 - 18
= 8
So, only 8 accident involved Alcohol but not excessive speed.
The Total number of Accidents investigated = P(A Only) + P( E only) + P(A ∩ E) + P( neither A U B)
= 8 + 12 + 18 + 21
= 59
Therefore, 59 accidents were investigated.
If it is February, then it is, as it has 28 days, but every four years, it has 29, so if you round to the nearest 7, then it is yes, but if exact, no.
