A study was being conducted about birth weights of babies at a local hospital and found the average to be 7.6 pounds with a standard deviation of 1.3 pounds (the distribution was approximately normal). Many pre-mature births weights are in the lowest 1% of births. What would be the birth weight associated with the lowest 1%?
Answer:
The birth weight associated with the lowest 1% is 4.6 pounds.
Step-by-step explanation:
Let X represent the birth weights of babies.
It is provided that [tex]X\sim N(7.6,1.3^{2})[/tex]
It is also provided that many pre-mature births weights are in the lowest 1% of births.
Let x represent the births weights that are in the lowest 1% of births.
That is, P (X < x) = 0.01.
⇒ P (Z < z) = 0.01
The corresponding z-score is, z = -2.33.
Compute the value of x as follows:
[tex]z=\frac{s-\mu}{\sigma}\\\\-2.33=\frac{x-7.6}{1.3}\\\\x=7.6-(1.3\times 2.33)\\\\x=4.571\\\\x\approx 4.6[/tex]
Thus, the birth weight associated with the lowest 1% is 4.6 pounds.

Complete the ordered pair for both equation. Will give brainiest
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So if you know that order pairs go like (x,y) that means that the 12 in (12,y) is the x so if we plug into the equation we can get y...
[tex]y=\frac{2}{3} (12)+ 5\\y=8+5\\y=13[/tex]
So the order pair is (12, 13).
Now for the next one it's the same concept but this time we'll plug in for y because the -2 is in the (x, y) so we have to find the x...
[tex]5x-9(-2)=3\\5x+18=3\\5x=-15\\x=-3[/tex]
So the order pair is (-3, -2).

5) Kareem Abdul-Jabbar holds the NBA record for the most points scored in a
career, 38,387. In the first 280games of his career, LeBron James has scored 7446
points. At this rate, how many more games willLeBron James need to play to
break Abdul-Jabbar's career record?
Answer:
Step-by-step explanation:
LeBron James need to play to 1444 games to break Abdul-Jabbar's career record.
What is rate of change?A rate of change is a rate that describes how one quantity changes in relation to other.
Given world record Kareem Abdul-Jabbar = 38,387 points.
Games played by LeBron = 280 games
Score of LeBron = 7446 points
Hence for each point LeBron has to play = 280/7446 games
Therefore to break the world record number of games required
= (280*38,387)/7446
number of games required = 1443.5
or, number of games required = 1444
Hence,at this rate LeBron James need to play to 1444 games to break Abdul-Jabbar's career record.

Which table has a constant of proportionality between y and x of 0.3
when you multiply the x number in the table c by 0.3 you get the same answer as the one in the y column. The constant of proportionality is the value that stays constant in the ratio. Since when you multiply each number in the x column by 0.3 and you always get the number in the y column it shows that the table c is correct.

heather has red and green pens in her stationery cupboard. the ratio of green pens to the total number of pens is 4:11
what fraction of heathers pens are green
what is the ratio of green pens to red pens
heather has 56 red pens. how many green pens does she have
Step-by-step explanation:
Pen colors given = Red and green
Ratio;
Green pen : Total pen
4 : 11
Solution:
1. what fraction of heathers pens are green;
Fraction = [tex]\frac{green pen}{total pen}[/tex] = [tex]\frac{4}{11}[/tex]
2. Ratio of green pens to red pens:
let the multiples = x
Green pen Red pen Total pen
4x ? 11x
Red pen = 11x - 4x = 7x
Ratio of green pen to red pen:
4 : 7
3. heather has 56 red pens. how many green pens does she have
Number of red pen = 56;
Number of green pens = ?
Since the ratio is;
4 : 7
Number of green pen = [tex]\frac{56 x 4}{7}[/tex] = 32

What line is perpendicular to y=2/7x+11/7 travel through (-3,8)
Answer:
2y- 16 = 7x + 21
Step-by-step explanation:
Y= mX+ c
y = (2/7)x + 11/7
m= gradient= 2/7
The perpendicular gradient should be the negative reciprocal of the gradient we have now.
which is : -1÷(2/7) = -7/2
Now for the perpendicular line equation, we have:
y = 8x= -3m= 7/2y - y1 = m ( x - x1 )
y - 8 = 7/2 ( x + 3 )
2y - 16 = 7x + 21

Answer:
I believe it is 1 and 3 only. (I & III only)
Step-by-step explanation:
5(-1) = -5
-5 - 10 is less than -5, so I is true.
5(9) = 45
45-10 is not less than -5, so II is false.
5(1) =5
5-10 is equal to -5, so III is true.
Answer:
I. and III.
Step-by-step explanation:
5x - 10 ≤ -5
I. -1
5(-1) - 10 ≤ -5
-5 - 10 ≤ -5
-15 ≤ -5
-15 is less or equal to -5, thus I. is an option
II. 9
5(9) - 10 ≤ -5
45 - 10 ≤ -5
35 ≤ -5
35 is not less or equal to -5, thus II. is not an option
III. 1
5(1) - 10 ≤ -5
5 - 10 ≤ -5
-5 ≤ -5
-5 is less or equal to -5, thus III. is an option
