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:

I think the correct answer is $19 per uniform.

Step-by-step explanation:

9x15=135  420-135=$285   285 divided by 15 is $19

 Hope this is right and helps you!

Answer:

$19

Step-by-step explanation:

Lets make an equation to represent this problem.

The coach is buying each player a basketball ($9) and a uniform, the unknown amount. Lets represent the unknown cost of the uniform with x.

The coach spent a total of $420.

Since the coach is buying 15 basketballs and 15 uniforms, our equation would look like:

15(9) + 15(x) = 420

First, multiply 15 * 9 and 15 * x

We get:

135 + 15x = 420

Subtract 135 from both sides

135 + 15x - 135 = 420 - 135

We get:

15x = 285

Divide by 15 on both sides.

[tex]\frac{15x}{15}[/tex] = [tex]\frac{285}{15}[/tex]

We get:

x = 19

So, 1 uniform equals $19

Step-by-step explanation:

Yes correct.

Commutative property upon integer addition/subtraction

-3 + 2 = 2 - 3

Answer:

Tim is 12 years

Step-by-step explanation:

Given that Zac is 18 years old and Tim's age is 2/3 Zac's age, to compute Tim's age, we would multiply Zac's age with the fraction.

Such that;

Tim's age = 2/3 * 18

= 2* 18/3

= 2 * 6

= 12 years

Hence Tim is 12 years old.

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:

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.

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

Answer: 3.707, 3.71, 3.8, 3.809, 3.83, 3.89

Answer:

Step-by-step explanation:

Remark

They all start with 3, so there is no difference to be had there.

Now you look at the tenths place.

There are two choices there. Both are 3.7. You have to go to the hundredths place to see the difference.

The very smallest one is 3.707. There's a 0 in the hundredth place.

The next one is in the 1 in the hundreds place so the next one is 3.71

That's two of the six taken care of.

3.8 comes next. There's nothing in the hundredths place.

3.809 comes next because it has a zero in the hundredths place.

3.83 is next

3.89 is last and largest.

Answer

3.707   3.71    3.8    3.809     3.83    3.89

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.

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.
