Answer:

24

Step-by-step explanation:

Here is the full question used in answering this question :

Francine wants to find a total of 2/3 cup of blueberries and 5/8 cup of raspberries what is the least common denominator of the fractions

Least common denominator of fractions is the smallest number that can divide both the denominator of 2/3 and the denominator of 5/8. The denominators here are 3 and 8

The least common denominator = 3 x 8 = 24

1Y, the number of accidents per year at a given intersection, is assumed to have a Poisson distribution. Over the past few years
miss Akunina [59]

Answer:

The probability that the intersection will come under the emergency program is 0.1587.

Step-by-step explanation:

Lets divide the problem in months rather than in years, because it is more suitable to divide the period to make a better approximation. If there were 36 accidents in average per year, then there should be 3 accidents per month in average. We can give for the amount of accidents each month a Possion distribution with mean 3 and variance 3.

Since we want to observe what happen in a period of one year, we will use a sample of 12 months and we will take its mean. We need, in average, more than 45/12 = 3.75 accidents per month to confirm that the intersection will come under the emergency program.

For the central Limit theorem, the sample mean will have a distribution Normal with mean 3 and variance 3/12 = 0.25; thus its standard deviation is √0.25 = 1/2.

Lets call the sample mean distribution X. We can standarize X obtaining a standard Normal random variable W with distribution N(0,1).

W = \frac{X-\mu}{\sigma} = \frac{X-3}{1/2} = 2x-6

The values of \phi , the cummulative distribution function of W, can be found in the attached file. We are now ready to compute the probability of X being greater than 3.75, or equivalently, the probability than in a given year the amount of accidents is greater than 45, leading the intersection into an emergency program

P(X > 3.75) = P(2X-6 > 2*3.75-6) = P(W > 1) = 1-\phi(1) = 1-0.8413 \\= 0.1587

Find the distance between the points (13, 20) and (18, 8).<br> 13<br> 7<br> 11
Lana71 [14]

Answer:  13

Step-by-step explanation:

See attached graph.

A third point (18,20) may be added to the two given points to form a right triangle with sides 5 and 12.  The distance, x, between the original two points is given by x^2 = 5^2 + 12^2

x^2 = 25 + 144

X^2 = 169

x = 13

What is the first step to solve the equation 16x-21 = 52?
Makovka662 [10]

Answer:

2) Add 21 to both sides

Step-by-step explanation:

When solving 16x-21=52 for x, our goal to isolate x such that we have x set equal to something.

Therefore, we want to start by adding 21 to both sides. This leaves us with 16x=73 and we are one step closer to isolating x.
