Hong Made 2 Identical Necklaces, Each Having Beads And A Pendant. The Total Cost Of The Beads And Pendants

Answers

Answer 1
b+ p= 10.40
b=2x 2.50
Now using substitution method replace b in first equation with value of second equation basically combing the two equations into one do you end up with one variable to solve .
2 x 2.50 +p =10.40
5 + p=10.40
P=$5.40
b =$5.00
The answer is EACH pendant cost $2.70
(You have to divide 5.40 by two )

What is the value of x?

Answers

Answer:

x = 24

Step-by-step explanation:

(2x - 4) + (3x + 5) + (2x + 11) = 180°

Combine like terms:

7x + 12 = 180

Subtract 12 on both sides:

7x = 168

Divide 7 on both sides:

x = 24

X=24 in this equation.

Consider the following statement: Two sets of data with the same mean will also have the same variability. Do you agree or disagree with this statement? Explain.


Answers

disagree because most of the times statistical questions or mainly yes or no questions and never really in the middle. that’s because it can throw off it’s variability! i hope i helped ❤️

The statement is false and same mean can have different variability

What is Mean?

The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Mean = Sum of Values / Number of Values

Given data ,

Let the mean of the data be represented as M

Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.

For example, consider the following two sets of data:

Set 1: 1, 2, 3, 4, 5 (mean = 3)

Set 2: 0, 2, 3, 4, 6 (mean = 3)

Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.

Hence , two sets of data with the same mean can have different variability,

What is the value of x and the measure of ∠LNM, respectively?

A. x = 25 ; ∠LNM = 155
B. x = 155 ; ∠LNM = 25
C. x = 45 ; ∠LNM = 135
D. x = 135 ; ∠LNM = 45

Pls dont put nonsense answer thank you

Answers

Linear pair of angles are of 180°. So,

45°+3x = 180°

=> 3x = 180°-45°

=> 3x = 135°

=> x = 135°/3

=> x = 45°

Answer:

Option C: x = 45, ∠LNM = 135

Step-by-step explanation:

Both the angles are supplementary which means they both add up to a straight angle or 180°;

45 + 3x = 180

=> First subtract 45 on each side of "="

3x = 135

=> Now divide both sides of "=" by 3

x = 45

Now to find measure of angle LNM, substitute in 45 for x

3x = ∠LNM

3(45) = ∠LNM

135 = ∠LNM

Hope this helps!

What is the value of x and the measure of ∠WZX, respectively?

A. x = 34 ; ∠WZX = 43
B. x = 43 ; ∠WZX = 34
C. x = 50 ; ∠WZX = 41
D. x = 41 ; ∠WZX = 50

Answers

Answer:

x = 43

Step-by-step explanation:

Supplementary angles = 180°

So,

(3x + 17) + (x - 9) = 180°

Combine like terms:

4x + 8 = 180

Subtract 8 on both sides

4x = 172

Divide 4 on both sides

x = 43

the probability is 3/25

First you add all of the things in the basket together. 8 + 2 + 6 + 4 = 20.

For Oreos, you have 8 in the basket so you divide 8 by how many is in the basket to get 2/5.

Then you divide 6 by the total amount which is 6/20 to get 3/10.
