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.

Answer:

X≤10/7

Step-by-step explanation:

7x-4≤6

add 4 both sides

7x-4+4≤6+4

7x≤10

divide 7 both sides

7x/7≤10/7

x≤10/7

hope it's helpful ❤❤❤❤

THANK YOU.

The solution of the given inequality is x≤10/7.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The given inequality can be simplified for the value of x as shown below.
7x − 4 ≤ 6

Add 4 both sides,

7x - 4 + 4 ≤  6 + 4

7x≤10

Divide 7 both sides,

7x/7 ≤ 10/7

x ≤ 10/7

Hence, the solution of the given inequality is x≤10/7.

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]

Answer:

x is less than or equal to 3

Step-by-step explanation:

The dot is a closed dot, which means that it is something or equal to, and the arrow is pointing down, which means less than. So the sign would be less than or equal to (sorry I don't have that sign on my computer). The dot is on three, so the inequality is x is less than or equal to 3.

Commutative property upon integer addition/subtraction

-3 + 2 = 2 - 3

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

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.

Step-by-step explanation:

Answer:

Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.

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.

x = 95

Step-by-step explanation:

(2x - 60)° = (x + 35)° (corresponding angles are congruent)

2x - 60 = x + 35

2x - 60 - x = x + 35 - x

x - 60 = 35

x - 60 + 60 = 35 + 60

Answer:

2.5

Step-by-step explanation:

(I'm assuming you're doing this the same way I learned it, if not I'm sorry if it doesn't make sense)

[tex]\frac{2}{x}[/tex]=[tex]\frac{12}{15}[/tex]

Cross multiply

12x=30

Divide

x=2.5

This is just one way to do the problem. An easier way is to simplify the fractions.

[tex]\frac{2}{x}[/tex]=[tex]\frac{4}{5}[/tex]

You can either cross multiply or figure out that 2 is half of four and simply divide 5 by 2 which will also result in 2.5
