Which of the following represents a positive integer?
9º below zero
A deposit of $50
A weight loss of 10 pounds
Answer: A deposit of 50$
Step-by-step explanation:
First, 9 Degrees below 0. 0-9 is -9 so this is a negative integer.
Second, deposit of 50$ so pretend your bank amount is x so x+ 50$ would be x + 50! Which is a positive integer
Finally, A weight loss of 10 pounds, x- 10 is probably a negative integer.

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

ols help and hurry ASAP Find m4+ 1/m4 , if m− 1/m =3.
Answer: 257/16
Step-by-step explanation:
You are given the algebraic expression: m^4+ 1/m^4
if m− 1/m = 3
Solve for m by cross multiplying
m - 1 = 3m
Collect the likes terms
3m - m = -1
2m = -1
m = -1/2
Substitutes m into the algebraic expression above.
(- 1/2)^4 + 1/(- 1/2)^4
Open the bracket
1/16 + 1/(1/16)
1/6 + 16
16(1/16) or 257/16

Describe what happens to the Car as it moves from BLUE to B"L"U"E".
Answer: As the car moves from "BLUE" to "B"L"U"E", it slows down its acceleration, reaches its maximum velocity, and then decelerates. The change in the car's motion is due to the change in the slope of the graph from positive to zero to negative. At "BLUE", the car has the highest positive slope, which represents the maximum acceleration. As the car moves towards "B"L"U"E", the slope of the graph decreases and becomes zero at the highest point of the graph. At this point, the car has reached its maximum velocity, and it starts to decelerate towards "B"L"U"E". Finally, at "B"L"U"E", the slope of the graph is negative, indicating that the car is decelerating.
Step-by-step explanation:
How far did I travel to reach my destination on each day of my three-day Trip?
a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination.
b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
The total distances you traveled to reach your destination on each day of your three-day trip are as follows:
a) Day 1 = 40 miles
b) Day 2 = 30 miles
c) Day 3 = 11 miles.
How the total distances are determined:The total distances are determined using proportions.
Proportion refers to the fractional value of the whole number or quantity.
a) Day 1:
The fractional distance traveled = ⁵/₈
The remaining distance to travel = 15 miles
15 miles = ³/₈ (1 - ⁵/₈)
Proportionately, the total distance = 40 miles (15 ÷ ³/₈)
b) Day 2:
The distance traveled = 18 miles
The remaining distance to travel = ²/₅
The distance traveled = ³/₅ (1 - ²/₅)
³/₅ = 18 miles
Proportionately, the total distance = 30 miles (18 ÷ ³/₅)
c) Day 3:
The distance traveled = ⁵/₁₁
The distance to travel = 6 miles
The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)
Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

If the probability of a chance event is 0.21, it is more likely to happen than which of the following probabilities of a different chance event?
Answer:
Step-by-step explanation:
If the probability of a chance event is 0.21, it is more likely to happen than any probability less than 0.21. In other words, it is more likely to occur than any event with a probability smaller than 0.21.

Find all possible values of a such that ax² + (2a + 2)x + a + 3 = 0 has two roots and the distance between them on the number line is greater than 1.
Answer:
\(-2\sqrt{2}-2 < a < 2\sqrt{2}-2,\;\;a\neq0\)
Step-by-step explanation:
Given quadratic equation:
\(ax^2 + (2a + 2)x + a + 3 = 0\)
To find the possible values of "a" such that the given equation has two roots and the distance between them on the number line is greater than 1, use the quadratic formula.
\(\boxed{\begin{minipage}{4 cm}\underline{Quadratic Formula}\\\\$x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}$\\\\when $ax^2+bx+c=0$ \\\end{minipage}}\)
Comparing the coefficients:
\(a = a\)\(b = (2a + 2)\)\(c = (a + 3)\)Substitute the coefficients into the quadratic formula:
\(x=\dfrac{-(2a+2) \pm \sqrt{(2a+2)^2-4a(a + 3)}}{2a}\)
Simplify the discriminant (the part under the square root sign):
\(x=\dfrac{-(2a+2) \pm \sqrt{-4a+4}}{2a}\)
Factor out 4 from the discriminant:
\(x=\dfrac{-(2a+2) \pm \sqrt{4(-a+1)}}{2a}\)
\(\textsf{Apply the radical rule:} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}\)
\(x=\dfrac{-(2a+2) \pm \sqrt{4}\sqrt{-a+1}}{2a}\)
Therefore:
\(x=\dfrac{-(2a+2) \pm 2\sqrt{-a+1}}{2a}\)
Factor out the common term 2:
\(x=\dfrac{-(a+1)\pm \sqrt{-a+1}}{a}\)
Therefore, the two solutions are:
\(x=\dfrac{-a-1+\sqrt{-a+1}}{a},\;\;x=-\dfrac{a+1+\sqrt{-a+1}}{a}\)
As both solutions have "a" as their denominator, a ≠ 0.
Note: When substituting a = 0 into the original equation, we are left with a linear equation, which only has one root. Therefore, this confirms that a ≠ 0.
Now we have found expressions for the two roots, we can set the distance between them to greater than 1:
\(\dfrac{-a-1+\sqrt{-a+1}}{a}-\left(-\dfrac{a+1+\sqrt{-a+1}}{a}\right) > \:1\)
\(\dfrac{-a-1+\sqrt{-a+1}}{a}+\dfrac{a+1+\sqrt{-a+1}}{a} > \:1\)
Simplify:
\(\begin{aligned}\dfrac{-a-1+\sqrt{-a+1}+a+1+\sqrt{-a+1}}{a}& > 1\\\\\dfrac{2\sqrt{-a+1}}{a}& > 1\\\\2\sqrt{-a+1}& > a\\\\(2\sqrt{-a+1})^2& > a^2\\\\4(-a+1)& > a^2\\\\-4a+4& > a^2\\\\a^2+4a-4& < 0\\\\(a+2)^2-8& < 0\\\\(a+2)^2& < 8\end{aligned}\)
\(\textsf{For\;\;$u^n < a$,\;\;if\;$n$\;is\;even\;then\;\;$-\sqrt[n]{a} < u < \sqrt[n]{a}|$:}\)
\(-\sqrt{8} < a+2 < \sqrt{8}\)
Therefore:
\(-\sqrt{8} -2 < a < \sqrt{8}-2\)
\(-2\sqrt{2}-2 < a < 2\sqrt{2}-2\)
So the possible values of "a" such that ax² + (2a + 2)x + a + 3 = 0 has two roots and the distance between them on the number line is greater than 1 are:
\(\large{\boxed{-2\sqrt{2}-2 < a < 2\sqrt{2}-2,\;\;a\neq0}\)

The parallelogram shown below has an area of 404040 units^2 2 squared.
Find the missing base.
Question:
The parallelogram shown below has an area of 40 units squared.
Find the missing base.
Answer:
See Explanation Below
Step-by-step explanation:
The question is incomplete as the diagram which shows the dimension of the parallelogram is not attached.
However, I'll give a general explanation on how to get the base of the parallelogram. If you follow this explanation, you'll get the right answer regarding your question.
The area of a parallelogram is calculated as thus.
Area = Base * Height
Given that the area = 40 units²
Let's assume the height of the parallelogram is 10 unit.
All you need to do is to plug in these values in the formula above..
Area = Base * Height becomes
40 = Base * 10
Divide both sides by 10
40/10 = Base * 10/10
4 = Base
Hence, Base = 4 units
Or take for instance the height is 5 units.
You'll still follow the simple steps as it is above.
Area = Base * Height becomes
40 = Base * 5
Divide both sides by 5
40/5 = Base * 5/5
8 = Base
Hence, Base = 8 units

The sum and the difference between the GCF and the LCM of two numbers is 252 and 180 respectivley. Find the 2 numbers if one is 1.5 greater than the other.
Answer:
108 and 72
Step-by-step explanation:
You are given ...
GCF +LCM = 252
GCF -LCM = 180
2×GCF = 432 . . . . . add the two equations
GCF = 216
Then the LCM is 216 -180 = 36
This is what your problem statement says. Usually, we expect the least multiple to be somewhat larger than the greatest factor.
_____
If we assume the problem statement intends that the sum and difference between the LCM and the GCF are 252 and 180, respectively, then ...
GCF = 36
LCM = 216
The product of the unique factors is 216/36 = 6. The ratio of the unique factors is 1.5 : 1 = 3 : 2. That is, the unique factors are 3 and 2, and the numbers are ...
3(36) = 108 and 2(36) = 72
The two numbers are 108 and 72.
