The set of whole numbers includes zero, but the natural numbers do not.
OA. True
OB. False
SUBMIT
Answer: True
The set of whole numbers is {0, 1, 2, 3, 4, 5, ...}
The set of natural numbers is {1, 2, 3, 4, 5, ...}
Both sets describe numbers that are positive and without any fractional or decimal component. The only difference is that 0 is included in the first set, but exclude from the second. If you want to include negative whole numbers as well, then you'd use the set of integers.
The given statement is true.
What is number?A number is an arithmetic value used to represent quantity. Hence, a number is a mathematical concept used to count, measure, and label. Thus, numbers form the basis of mathematics.
The statement given is says that, the set of whole numbers includes zero, but the natural numbers do not.
So, if we see the definition of both types of numbers, we can say that the whole numbers are the natural starting from 0, and the natural numbers are the one which includes only counting numbers used in our daily life.
Hence, the given statement is true.

Rodney packs 4 shirts for a trip at random. The closet contains 10 shirts: 5 striped, 3 plaid, 2 solid colored ones. What is the probability that he chose 2 striped and 2 plaid
Answer:
1 / 7
Step-by-step explanation:
Given :
Number of shirts in closet = 10
Number of striped shirt = 5
Number of plaid = 3
Probability of choosing 2 plaid shirts and 2 stripped shirt
Probability = required outcome / Total possible outcomes
Total possible outcomes = 10C4
Required outcome :
2 plaid shirt from 3 = 3C2
2 stripped shirts from 5 = 5C2
Hence,
P(choosing 2 plaid and 2 stripped shirt) :
(3C2 * 5C2) / 10C4
Recall:
nCr = n! / (n-r)!r!
Using calculator :
(3C2 * 5C2) / 10C4
= (3 * 10) / 210
= 30 / 210
= 1 / 7
What is 0.4 written as a percentage (show work if can)
Answer:
40%

C. 100,000 -2.2.2.2.2
D. 100,000 - 5 with the power of 2
E. 100,000 - 2 with the power of 5
Answer:
The answer is C and E.
Step-by-step explanation:
I just took the assignment and it is C and E.
The expression that represents the population after 5 decades is
100,000 x [tex]2^5[/tex] or 100,000 x 2 x 2 x 2 x 2 x 2.
Options C and E is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 8 is an equation.
We have,
The population of the city = 100,000
Population doubles every decade.
This means,
Population after 1 decade.
= 100,000 x 2
= 200,000
Population after 2 decades.
= 200,000 x 2 x 2
= 800,000
We can write an expression for the population after x decade.
= 100,000 x [tex]2^x[/tex]
The population after 5 decades.
= 100,000 x [tex]2^5[/tex]
= 100,000 x 2 x 2 x 2 x 2 x 2
= 100,000 x 32
= 3200,000
Thus,
The expression is 100,000 x [tex]2^5[/tex] or 100,000 x 2 x 2 x 2 x 2 x 2.

Answer:
Step-by-step explanation:
p + n + d + q = 25
Put everything into quarters.
p and q are equally likely to be drawn
q + n + d + q = 25
There are 3 times as many nickels as quarters
n = 3q
q + 3q + d + q = 25
There is 25% more dimes than quarters.
d = 1.25 q
q + 3q + 1.25q + q = 25
6.25 q = 25
q = 25/6,25
=====================
q = 4
p = 4
d = 1.25 * 4 = 5

all angles should add to 180
180-56=124
124÷2=62
Answer:
Step-by-step explanation:
1st notice that two of the sides are the same length? ( isosceles ) that mean the two angles at the "base" which is the side that both of the same size legs tie into... that's the side that is 4.5 in the picture. soooo if both of those angles are the same.. and we know that the angles are going to add to 180 then.... we can say the the 56° is the same as the one at the other end of the 4.5 side (base) so 2*56°=112°
and then 112° + x = 180°
x = 180-112
x = 68°

Stefan sells Jin a bicycle for $137 and a helmet for $17. The total cost for Jin is 140% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make bying the bicycle and helmet to Jin? Stefan originally spent $
Answer:
Stefan originally spent $110.
Stefan made a profit of $44.
Step-by-step explanation:
Given that:
Stefan sold the bike and helmet for $137 and $17
Total amount = 137+17 = $154
This is 140% of the price Stefan originally paid.
Let,
x be the original price paid by Stefan
140% of x = $154
[tex]\frac{140}{100}x=154\\1.4x = 154\\\frac{1.4x}{1.4}=\frac{154}{1.4}\\x=110[/tex]
Therefore,
Stefan originally paid $110 for the bicycle and helmet.
Profit made by Stefan = 154-110 = $44
Hence,
Stefan originally spent $110.
Stefan made a profit of $44.

What is the percent change from 80 to 20? I’m confused
Answer:
75% decrease
Step-by-step explanation:
To calculate the percentage increase:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
If your answer is a negative number, then this is a percentage decrease.
To calculate percentage decrease:
First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
If your answer is a negative number, then this is a percentage increase.
