Assume that emergency medical personnel in California are planning for future resources and it has been observed that the averag

e number of traffic accidents requiring ambulance assistance on the Hollywood Freeway between 7 and 8 AM on Wednesday mornings is 1.1. What, then, is the probability that there need for exactly 2 ambulances on the Freeway during that time slot on any given Wednesday morning?

Answer:

Answer is 0.5

Step-by-step explanation:

The text implies that the number of traffic accidents determines the number of ambulances required on the road. Hence, 1 traffic accident requires 1 ambulance.

The time slot and time of day remain same in both the text and the question.

The average or mean number of accidents is 1.1

QUESTION: What then is the probability that there is need for exactly 2 ambulances on that road and in that time frame?

In other words, what is the probability that there'll be 2 accidents on that road and in that time frame?

Since the mean number of accidents is 1.1,  2 is above the mean.

Probability of 1.1 accidents is 1, since that's the mean (expected value).

Probability of 2 accidents is 1/2 which is = 0.5

The volume of a square pyramid with a height of 12m is 100 m find the Length of the square base.
Vikki [24]
Volume of square Pyramid = a^2 * h/3
If we rearrange that equation to give a (length of square base)

a = (sqrt(3)* sqrt(V))/sqrt(h)
a = (sqrt(3)* sqrt(100))/sqrt(12)
a = 5m

Answer:

Part a) The rule of the sequence is A(n)=50(0.52^{n-1})

Part b) The height of the ball will be 13.52\ cm

Step-by-step explanation:

Part a) Write a rule for the sequence using centimeters. The initial height is given by the term n = 1.

we know that

In a <u>Geometric Sequence</u> each term is found by multiplying the previous term by a constant called the common ratio (r)

In this problem we have a geometric sequence

Let

n-----> the number of path

a1 ----> is the initial height

r -----> the common ratio

we have

a1=0.5\ m=0.5*100=50\ cm

r=52\%=52/100=0.52

The rule for the sequence is equal to

A(n)=a1(r^{n-1})

substitute

A(n)=50(0.52^{n-1})

Part b) What height will the ball be at the top of the third path?

For n=3      

substitute in the equation

A(3)=50(0.52^{3-1})  

A(3)=50(0.52^{2})

A(3)=13.52\ cm

Answer:

m = 2

Step-by-step explanation:

take 2 pairs from x

choose (1,5) and (2,7)

it will be m = 5 - 7

and in the bottom  1 - 2          it's a fraction

m = -2/-1

the numerator and denominator can't be both negative

so your answer is m= +2

m= slope

rate of change= slope

When creating vases for the craft fair, Thomas used the proportion 3 pounds of clay is to 8 vases as 9 pounds of clay is to 24 v
Elodia [21]

Answer:

Answer:

4/24

Step-by-step explanation:

Because 1/6 is 4/24 simplified.

To prove this, all you have to do is try simplifying 4/24 yourself. To do that, we are going to use 4 to divide both the numerator and the denominator because 4 is a common factor of 4 and 24.

(To simplify a fraction, you divide both the numerator and denominator by a common factor)

So 4 divided by 4 is 1, and 24 divided by 4 is 6

1/6

99% sure im right ;)
