What is the fractional value of A?

After examining a child at his 2-year checkup, the boy's pediatrician said that the z-score for his height relative to other 2-y

Anna [14]

Answer:

Step-by-step explanation:

The pediatrician said that the z-score for the boy's height, relative to other 2-year-olds in the country, was 1.59

He explains to the parents of the boy, that the extreme 5% of cases often require special attention.

(A) Does this child fall into that group?

Yes, this child falls into that group. He is among the extreme 5% of cases at the tail of the distribution.

(B) What do you need to assume about the heights of 2-year-olds, in order to find your answer to part (A)?

Assume that the distribution of heights is skewed, the heights are independent of one another, and the number of heights is very large.

Anestetic [448]

Answer:

The original number is 72

Step-by-step explanation:

72 swapping digits around results in 27

1/3 of 72 = 24

24 + 3 = 27

Answer:

y=3/4x+7

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-4,4) and has a slope of 3/4. 

First of all, remember what the equation of a line is: 

 

y = mx+b 

Where: 

m is the slope, and 

b is the y-intercept 

To start, you know what m is; it's just the slope, which you said was 3/4. So you can right away fill in the equation for a line somewhat to read: 

y=3/4x+b. 

Now, what about b, the y-intercept? 

 

To find b, think about what your (x,y) point means: 

(-4,4). When x of the line is -4, y of the line must be 4. 

Because you said the line passes through this point, right? 

Now, look at our line's equation so far: . b is what we want, the 3/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,4).

 

So, why not plug in for x the number -4 and for y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!. 

 

(-4,4). y=mx+b or 4=3/4 × -4+b, or solving for b: b=4-(3/4)(-4). b=7.

hope this answers your question sorry it's soo long i just like writing long stuff have a great day!!
