Answer:
Babies of 33 week weighs relatively less than the babies of 41 week.
Explanation:
Z score is determined by
x-u/sd
A) For 33 Week baby
Given
Mean 2500
SD 800
Z score is
2600-2500/800 =0.125
B) For 41 Week baby
Given
Mean 2800
SD 425
x=2900
Z score is
2900-2800/425 =0.235
The z score depicts that the baby of 33 week or 41 week weighs more than the normal babies of same age group.
Thus, babies of 33 week weighs relatively less than the babies of 41 week.

Step-by-step explanation:
To solve the given quadratic equations, equate to zero, factorise and solve
given
x² - 19x + 48 = 0
Consider the factors of the constant term (+ 48) which sum to give the coefficient of the x- term (- 19)
The required factors are - 3 and - 16, hence
(x - 3)(x - 16) = 0
equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 16 = 0 ⇒ x = 16
----------------------------------------------------------------
given
x² + 21x - 100 = 0
Consider the factors of the constant term (- 100) which sum to give the coefficient of the x- term (+ 21)
The required factors are + 25 and - 4, hence
(x + 25)(x - 4) = 0
x + 25 = 0 ⇒ x = - 25
x - 4 = 0 ⇒ x = 4
Answer:
(-7,4]
Step-by-step explanation:
I'm going to assume that you need this in interval form
The domain is just asking for all the possible x values
The x value that's furthest to the left is -7 and because it's an open circle we write ( instead of [
the furthest to the right the line goes is 4 and because the circle is closed it's written with ]
but it all together and get
(-7,4]
Answer: 1044cm
Step by Step Explanation :
- separate the shape into a rectangle and a square. Subtract 46 from 21
- the rectangular shape is 30cm by 25cm LxW its 750cm
- the smaller shape on the side is 21 cm by 14cm LxW its 294.
- Add. 294cm + 750cm = 1044cm
