Answer:
a) Normal Distribution
b) 0.146
c) 0.070
Step-by-step explanation:
We are given the following information in the question:
The number of accidents per week at a hazardous intersection varies with mean 2.2 and standard deviation 1.4
a)
: mean number of accidents per week at the intersection during a year (52 weeks)
According to central limit theorem, as the sample size becomes larger, the distribution of mean approaches a normal distribution.
Since we have a large sample, the approximate distribution of
is a normal distribution with

b) P(mean is less than 2)
Formula:

P(x > 610)

Calculation the value from standard normal z table, we have,

c) P(fewer than 100 accidents at the intersection in a year)
P(x < 100)

Calculation the value from standard normal z table, we have,

Answer:
2 and angle that is left of 5
Step-by-step explanation:
Angle 2 is vertical from 110, and vertical angles are congruent. From this, we can figure out that 2 and 3 (they're supplementary) are 70. Angles 5 and 3 are Alternate Interior Angles, and therefore must be congruent. The one to the left of 5 is supplementary to it, and therefore must be 110. Your answers are angle 2 and the angle that is left of 5.
Reponse:
Pour la mere, la variable independente est l'heure de se coucher. Les resultats scolaires sont la variable dependente.
Pour Tania, c'est le contraire. La variable independente est les resultats scolaires, et la variable dependente est l'heure de se coucher.
Answer:
152.4 cm
Step-by-step explanation:
multiply the length value by 30.48
97+ 54= 151
180-151= 29
29 is the answer
