The materials listed in the table below are called elements. They are substances that are found in nature. Some are metals, like aluminum, copper, iron, lead, silver, tin, and nickel. Some are gasses, such as hydrogen and oxygen.
We use all of these elements in everyday life. Pennies were originally copper, quarters were silver, and nickels were made of nickel. Most soda cans are aluminum. Water is made of hydrogen and oxygen, and we breathe oxygen. Salt is mostly made of sodium.
So, think about these materials and how heavy they would feel if you had a cubic centimeter of each one.
For each material listed in the table, find the mass for 1,000 cm3 in grams and kilograms. Then find the weight in pounds. Which material is the densest and which is the least dense? Why do you think this is true?

List the sample space for rolling a fair six-sided die. S = {1} S = {6} S = {1, 2, 3, 4, 5, 6} S = {1, 2, 3, 4, 5, 6, 7, 8}
Answers
Answer:
The sample space for rolling a fair six-sided die is: S = {1, 2, 3, 4, 5, 6}
The sample space represents all the possible outcomes of an event. In this case, the event is rolling a fair six-sided die, so the sample space is the set of all the possible numbers that can appear on the die, which are 1, 2, 3, 4, 5 and 6.
Option A, S = {1}, is incorrect because this only represents one outcome, not all possible outcomes.
Option B, S = {6}, is incorrect because this only represents one outcome, not all possible outcomes.
Option C, S = {1, 2, 3, 4, 5, 6}, is correct as it represents all possible outcomes.
Option D, S = {1, 2, 3, 4, 5, 6, 7, 8}, is incorrect because this includes numbers that cannot appear on a six-sided die, and it does not represent all possible outcomes.

As a nurse, part of your daily duties is to mix medications in the proper proportions for your patients. For one of your regular patients, you always mix Medication A with Medication B in the same proportion. Last week, your patient's doctor indicated that you should mix 120 milligrams of Medication A with 132 milligrams of Medication B. However this week, the doctor said to only use 121 milligrams of Medication B. How many milligrams of Medication A should be mixed this week?
Answers
Explanation: If last week was 132 milligrams of Medication B and 120 milligrams of Medication A. Then Medication B has is 12 milligram more then Medication A. So you would do 121 milligrams minus 12 milligrams to get Medication A for this week.

Only numbers greater than 5 satisfy the inequality.
The answer is a set that only contains numbers greater than 5.
Answer: {6, 8, 10}
The values that satisfies the condition n+5>10 among {2,4,6,8,10} is
{6,8,10}
let check the every value of {2,4,6,8,10} satisfies the condition n+5>10
let n=2
= n+5 = 2+5 = 7
7!>10
so 2 does not satisfies the condition
let n=4
= 4+5 = 9
9!>10
lly 4 does not satisfies the condition
let n= 6
=n+5 = 6+5 = 11
11>10 satisfies the condition
let n= 8
=n+5 = 8+5 = 13
13>10 satisfies the condition
let n= 10
=n+5 = 10+5 = 15
15>10 satisfies the condition
only {6,8,10} satisfies the given condition
What's the answer to b = and c =
Answers
Answer:
b = 21°
c = 159°
Step-by-step explanation:
To solve for B we have to know that the opposite angle is the same. So 21° is the same as angle b.
To solve for C we have to know that a line adds up to 180°. So 21° plus c = 180
To find this we do 180 - 21 = 159.
I hope this helps you :D
Answer:
B = 21
C = 159
Step-by-step explanation:
As we are given 21 degrees as one of the angles, we can also notice that both lines are straight, so they are both adding up to an angle of 180 each.
To find C, we can use this equation:
C + 21 = 180
C = 180-21
C = 159
To find B, we can use this equation:
B + C = 180
Plug in C:
B + 159 = 180
B = 180-159
B = 21

D. The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
E. The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
Answers
The statements that are true regarding the measures of center and variability of these data sets include:
A. The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
C. The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
E. The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
How to calculate the mean of any data set?In Mathematics and Statistics, the mean for any set of data can be calculated by using the following formula:
Mean, \bar{x} = ∑x/n
Where:
∑x represents the sum of all data values.n represents the total number of data items.Based on the information provided, we have:
Mean of Yard Works = (7+9+7+12+5)/5
Mean of Yard Works = 8.
Mean of Grow Station = (9+11+6+12+7)/5
Mean of Grow Station = 9.
Range is the difference between the maximum and minimum numbers;
Range of Yard Works = 12 - 5
Range of Yard Works = 7.
Range of Grow Station = 12 - 6
Range of Grow Station = 6.
Mean absolute deviation is given by;
MAD = 1/n ∑|x - μ|
Where:
n represents the number of data (observed values)μ represents the mean of the data set.x represents the individual data (values)Mean absolute deviation of Yard Works = 2
Mean absolute deviation of Grow Station = 2.

What's the value of x?
Answers
Answer:
x = 62
Step-by-step explanation:
Recall the properties of parallel lines with transversals. Vertical angles are congruent so the angle across from 118° is also 118°.
Recall the consecutive interior angles theorem. If two angles are on the same side of the transversal and are between the two parallel lines, then their measures add up to 180°. 180° - 118° = 62°.
Therefore, x = 62.

The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π.
Answers
Answer:
Step-by-step explanation:
A = πr^2
(153.86) = (3.14) r^2
Divide 3.14 on both sides.
49 = r^2
Square root both sides.
7 = r
D = 2r
D = 2(7)
D = 14
The diameter of the circle is 14 square meters.
Answer:
14 meters²
Step-by-step explanation:
Since the formula to find the diameter is d = 2r, we need to first find the radius, which can be r = square root of Aπ over π if we take the formula for the area of a circle and isolate the radius. After simplifying r = square root of 153.86π over π to 7 and multiplying that by 2, we get the circle's diameter of 14 meters. Hope this helps!
