32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 800 grams while babies born after a gestation period of 40 weeks have a mean weight of 2800 grams and a standard deviation of 370 grams. If a 32-week gestation period baby weighs 2375 grams and a 41-week gestation period baby weighs 2675 grams, find the corresponding z-scores. Which baby weighs less relative to the gestation period?
Find the corresponding z-scores. Which baby weighs relatively less? Select the correct choice below and fill in the answer boxes to complete your choice.
(Round to two decimal places as needed.)
A.
The baby born in week 32 weighs relatively less since its z-score, nothing, is smaller than the z-score of nothing for the baby born in week 41.
B.
The baby born in week 41 weighs relatively less since its z-score, nothing, is smaller than the z-score of nothing for the baby born in week 32.
C.
The baby born in week 41 weighs relatively less since its z-score, nothing, is larger than the z-score of nothing for the baby born in week 32.
D.

Answers
Answer:
Step-by-step explanation:
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.
Which equation represents a line which is parallel to the line
6x + 7y = –49?
Answers
Answer: y= 7/6x-5
Step-by-step explanation:
The equations of parallel lines have the same slope or rates.
The equation of the line parallel to [tex]\mathbf{6x + 7y = -49}[/tex] is [tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]
The equation is given as:
[tex]\mathbf{6x + 7y = -49}[/tex]
Make 7y the subject
[tex]\mathbf{7y = -6x-49}[/tex]
Make y the subject
[tex]\mathbf{y = -\frac{6}{7}x -7}[/tex]
A linear equation is represented as:
[tex]\mathbf{y =mx + b}[/tex]
Where m represents the slope.
So, we have:
[tex]\mathbf{m = -\frac 67}[/tex]
Parallel lines have the same slope.
So, the slope of the line is [tex]\mathbf{m = -\frac 67}[/tex]
The equation is then calculated as:
[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]
Substitute [tex]\mathbf{m = -\frac 67}[/tex]
[tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]
Hence, the equation of the line parallel to [tex]\mathbf{6x + 7y = -49}[/tex] is [tex]\mathbf{y = -\frac 67(x - x_1) + y_1}[/tex]

x minus 2 = 10
2 x = 4
3 x = 24
StartFraction x Over 2 EndFraction = 16
StartFraction x Over 8 EndFraction = 1
Answers
Answer:
The answers include
x + 2 =10
x - 4 = 4
3x = 24
Start Fraction x Over 8 End Fraction = 1
Step-by-step explanation:
x + 2 = 10; 8 + 2 = 10
x - 4 = 4; 8 - 4 = 4
3x = 24; 3(8) = 24
Start Fraction x Over 8 End Fraction = 1; 8/8 = 1
Equations with solution x = 8 are
x + 2 = 10,
x minus 4 = 4,
3x = 24,
Start Fraction x Over 8 End Fraction = 1
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given equations
x + 6 = 2
⇒ x = 2-6
⇒ x = -4
x + 2 = 10
⇒ x = 10 - 2
⇒ x = 8
x minus 4 = 4
x - 4 = 4
⇒ x = 4 + 4
⇒ x = 8
x minus 2 = 10
x -2 = 10
⇒ x = 10+2
⇒ x = 12
2x = 4
⇒ x = 4/2
⇒ x = 2
3x = 24
⇒ x = 24/3
⇒ x = 8
Start Fraction x Over 2 End Fraction = 16
x/2 = 16
⇒ x = 2(16)
⇒ x = 32
Start Fraction x Over 8 End Fraction = 1
x/8 = 1
⇒ x = 8(1)
⇒ x = 8
Hence, equations
x + 2 = 10,
x minus 4 = 4,
3x = 24,
Start Fraction x Over 8 End Fraction = 1
have 8 as solution.

b $448, 000

Answers
Answer:
c. $634,000
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
His initial cost is $28,000. Every decade the value of the house doubles. We are in year 1975. Let's add 10 years (a decade) 1975+10= 1985. Since we added ten years, we will double $28,000 which is $56,000. Let's add 10 more years 1985+10 is 1995. Since we added 10 years more, we double $56,000 which is $112,000. Now we can still add 10 more years. Do the same thing you did for the first and second decades. You should get the year 2005 and $224,000. We can still add 10 more years to get to 2020. Our year will be 2015 and our total amount in dollar is $224,000² = $448,000. Since the value doubles every decade you ignore the 5.
