I have 40 softballs i give 5 softballs to each player. How many players can i give softballs to so that i have at most 10 softballs left
Answer:
6
Step-by-step explanation:
5 to each players means you have 6 players and then you have 10 left for yourself
Answer:
You can hand out 5 softballs to 6 players.
Step-by-step explanation:
In order to solve this problem, you need to divide 30 balls to each player (In order to have 10 left.) 30 divided by 5 is 6, so you can only hand out 5 balls to 6 players in order to have 10 left out of 40.

Help me find BE please.
Answer:
BE = 6
Step-by-step explanation:
Fact regarding the centroids of a triangle.
On each median the distance from the vertex to the centroid is twice the distance from the centroid to the midpoint, thus
BD = 2DE, that is
4 = 2DE ( divide both sides by 2 )
DE = 2
Thus
BE = BD + DE = 4 + 2 = 6

What is the equation of the line that passes through (−5, 0) and (4, 3)?
A. y=1/3x+5/3
B. y=-1/3x-5
C. y=3x+15
D.y=-3x-15
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (4, 3)
m = \(\frac{3-0}{4+5}\) = \(\frac{3}{9}\) = \(\frac{1}{3}\) , thus
y = \(\frac{1}{3}\) x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 3) , then
3 = \(\frac{4}{3}\) + c ⇒ c = 3 - \(\frac{4}{3}\) = \(\frac{5}{3}\)
y = \(\frac{1}{3}\) x + \(\frac{5}{3}\) → A
The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

What is an equation of a line?The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.
The general equation of a straight line is y = mx + c.
m = slope
c = y-intercept
We have,
A line passes through (-5, 0) and (4, 3)
Slope = m is given by:
m = (d - b) / (c - a)
where (a, b) and (c, d) are the points where the line passes.
Now,
Slope =m = (3 - 0)/(4 - (-5)) = 3/(4+5) = 3/9 = 1/3
We have,
y = mx + c
We can assume any point (-5, 0) or (4, 3) to find the value of the y-intercept.
Case 1.
(-5 , 0) = (x, y)
0 = 1/3(-5) + c
0 = -5/3 + c
c = 5/3
Case 2.
(4, 3) = (x, y)
3 = (1/3)4 + c
3 = 4/3 + c
c = 3 - 4/3
c = 9 - 4 / 3
c = 5/3
We will get the same value for c in both cases.
We have,
m = 1/3 and c = 5/3
The equation of the line can be written as:
y = (1/3)x + 5/3.
Thus the equation of the line that passes through (-5, 0) and (4, 3) is
y = (1/3)x + 5/3.

Determine which is the better investment: 3.38% compounded semiannually or 3.51% compounded quarterly. Round your answers to 2 decimal places.
The 3.38% semiannual investment gives an effective rate of ____ %.
The 3.51% quarterly investment gives an effective rate of ____ %.
Therefore, the _______ investment is a better investment.
The 3.51% compounded quarterly investment is the better investment in terms of higher returns.
We need to compare the effective rates of return for both options in order to determine which investment is superior.
A) For the 3.38% accumulated semiannually, we can work out the successful rate utilizing the equation:
The effective rate is as follows: Effective Rate = (1 + (Annual Interest Rate / Number of Compounding Periods)) Number of Compounding Periods - 1 Annual Interest Rate = 3.38 percent Number of Compounding Periods = 2 (since it is compounded semiannually) Effective Rate = (1 + (0.0338 / 2)) 2 - 1
The 3.38% compounded semiannual investment has an effective rate of approximately 3.59%, which is calculated as follows: Effective Rate = (1 + 0.0169)2 - 1 Effective Rate 0.0359385 or 3.59% (rounded to two decimal places).
B) We can use the same formula to determine the effective rate for the quarterly compound interest rate of 3.51 percent:
Since it is compounded quarterly, there are four compounding periods, and the annual interest rate is 3.51 percent. The effective rate is equal to (1 + (0.0351 / 4))4 - 1.
The compounded quarterly investment at 3.51% has an effective rate of approximately 3.53%, which is calculated as follows: Effective Rate = (1 + 0.008775)4 - 1 Effective Rate 0.0353157 or 3.53% (rounded to two decimal places).
When we look at the effective rates, we can see that the compounded quarterly investment with a rate of 3.51 percent has a slightly higher effective rate (3.53%) than the compounded semiannual investment with a rate of 3.38 percent (3.59%). Consequently, the higher-return investment at 3.51 percent compounded quarterly is superior.

A grocery store sells a bag of 4 oranges for $2.56. What is the unit cost?
Answer:
$0.64
Step-by-step explanation:
customers arrive at a post office with a single server. fifty percent of the customers buy stamps, and take 2 minutes to do so. twenty percent come to pick up mail and need 3 minutes to do so. the rest take 5 minutes. assuming all these times are deterministic and that the arrivals form a poisson process with a rate of 18 per hour, compute the expected number of customers in the post office in steady state
the expected number of customers in the post office in steady state is 13.16.
We can use the M/M/1 queue model to solve this problem. Since customers arrive at a Poisson rate of 18 per hour, the arrival rate is λ = 18/60 = 0.3 customers per minute. The service times are deterministic, so we can use the mean service time to calculate the service rate. The mean service time is:
(0.5 x 2) + (0.2 x 3) + (0.3 x 5) = 3.1 minutes
So the service rate is μ = 1/3.1 = 0.3226 customers per minute.
The utilization of the system is ρ = λ/μ = 0.3/0.3226 = 0.929. Since the system is stable, the expected number of customers in the system in steady state is:
L = ρ/(1 - ρ) = 0.929/(1 - 0.929) = 13.16 customers

If the current interest A) $6,900.00 B) $6,057.48 C) $5,989.00 D) $7,567.65 E) $7,134.54
Therefore, Guy would be willing to pay approximately $5,989.00 today for this investment based on the expected cash flows and the interest rate. The correct option is C) $5,989.00.
The formula for present value of a series of cash flows is given by:
\(PV = C1/(1+r)^1 + C2/(1+r)^2 + C3/(1+r)^3 + ... + Cn/(1+r)^n\)
Where:
PV is the present value,
C1, C2, C3, ..., Cn are the cash flows at different time periods,
r is the interest rate, and
n is the number of time periods.
In this case, the cash flows are $2,000, $1,500, $3,000, and $400, occurring at the end of year 1, year 2, year 3, and year 4, respectively. The interest rate (r) is 6%.
Substituting these values into the formula, we have:
\(PV = 2,000/(1+0.06)^1 + 1,500/(1+0.06)^2 + 3,000/(1+0.06)^3 + 400/(1+0.06)^4\)
Simplifying the expression:
\(PV ≈ 2,000/1.06 + 1,500/1.06^2 + 3,000/1.06^3 + 400/1.06^4\)
Using a calculator, we find that PV ≈ $5,989.00.

Let f(x) = (3x + 9. Find f-'(x).=Vf-'(x) =help (formulas)
Given the function:
\(f\mleft(x\mright)=\sqrt{3x+9}\)You can find the Inverse Function by following the steps shown below:
1. Rewrite the function using:
\(f(x)=y\)Then:
\(y=\sqrt{3x+9}\)2. Solve for "x":
- Square both sides of the equation, in order to undo the effect of the square root on the right side:
\(\begin{gathered} (y)^2=(\sqrt[]{3x+9})^2 \\ y^2=3x+9 \end{gathered}\)- Apply the Subtraction Property of Equality by subtraction 9 from both sides of the equation:
\(\begin{gathered} y^2-(9)=3x+9-(9) \\ \\ y^2-9=3x \end{gathered}\)- Apply the Division Property of Equality by dividing both sides of the equation by 3:
\(\begin{gathered} \frac{y^2-9}{3}=\frac{3x}{3} \\ \\ \frac{y^2-9}{3}=x \\ \\ x=\frac{y^2-9}{3} \end{gathered}\)3. Swap the variables:
\(y=\frac{x^2-9}{3}\)4. Replace the variable "y" with:
\(y=f^{-1}(x)\)Then, you get:

suppose a and b are arbitrary sets such that |a|=n and |b|=m. then |a ∪ b|=n m-nm . a. true b. false
The statement is false. The correct formula to find the size of the union of two sets is |a ∪ b| = |a| + |b| - |a ∩ b|. Substituting the values given in the question, we get |a ∪ b| = n + m - |a ∩ b|.
We don't know anything about the intersection of sets a and b, so we cannot directly calculate |a ∩ b|.
However, we do know that |a ∩ b| is less than or equal to the minimum of |a| and |b|, which is min(n,m). Therefore, we can say that |a ∩ b| ≤ min(n,m).
Substituting this inequality into the formula for |a ∪ b|, we get:
|a ∪ b| = n + m - |a ∩ b|
≥ n + m - min(n,m)
We can simplify this expression by observing that if n ≤ m, then min(n,m) = n. If n > m, then min(n,m) = m. Therefore:
|a ∪ b| ≥ n + m - n = m
or
|a ∪ b| ≥ n + m - m = n
In either case, we have shown that |a ∪ b| is greater than or equal to the larger of |a| and |b|. Therefore, the given formula, |a ∪ b| = nm - nm, cannot be correct. The correct answer is b. false.
