A team of 22 soccer players needs to choose 3 players to fill water bottles. How many different groups can be made?

Answers

Answer 1

Answer:

1540

Step-by-step explanation:

To figure out the answer you must compute 22 choose 3. To compute this, we can plug the values into the Combination formula, which goes like this:

[tex]\frac{n!}{r!(n-r)!}[/tex], where n is the sample size, and r is the amount being chosen. In this case, n is equal to the total 22 players, and r is the 3 players being chosen to fill the bottles. Plugging the values in, we have the answer as

[tex]\frac{22!}{3!(22-3)!}[/tex]. 22 minus 3 simplifies to 19 factorial, and we can expand 22 factorial out from the numerator.

[tex]\frac{22(21)(20)(19!)}{3!(19!)}[/tex]

We can get rid of the 19 factorial from both the numerator and the denominator, and we are left with

[tex]\frac{22(21)(20)}{3(2)}[/tex]

We can cancel out the 3 with the 3 in 21, and we can cancel out the 2 with the 2 in 20. We are left with

[tex]22(7)(10)[/tex]

7 times 10 is equal to 70, and 70 times 22 is equal to 1540 total combinations.

A freshly inoculated bacterial culture of Streptococcus contains 100 cells. When the culture is checked 60 minutes later, it is determined that there are 450 cells present. Assuming exponential growth, determine the number of cells present at any time t (measured in minutes) and the find the doubling time.​

Answers

Answer:

[tex]P(t) = 100e^{0.0251t}[/tex]

The doubling time is of 27.65 minutes.

Step-by-step explanation:

Exponential equation of growth:

The exponential equation for population growth is given by:

[tex]P(t) = P(0)e^{kt}[/tex]

In which P(0) is the initial value and k is the growth rate.

A freshly inoculated bacterial culture of Streptococcus contains 100 cells.

This means that [tex]P(0) = 100[/tex]. So

[tex]P(t) = 100e^{kt}[/tex]

When the culture is checked 60 minutes later, it is determined that there are 450 cells present.

This means that [tex]P(60) = 450[/tex], and we use this to find k. So

[tex]450 = 100e^{60k}[/tex]

[tex]e^{60k} = 4.5[/tex]

[tex]\ln{e^{60k}} = \ln{4.5}[/tex]

[tex]60k = \ln{4.5}[/tex]

[tex]k = \frac{\ln{4.5}}{60}[/tex]

[tex]k = 0.0251[/tex]

So

[tex]P(t) = 100e^{0.0251t}[/tex]

Doubling time:

This is t for which P(t) = 2P(0) = 200. So

[tex]200 = 100e^{0.0251t}[/tex]

[tex]e^{0.0251t} = 2[/tex]

[tex]\ln{e^{0.0251t}} = \ln{2}[/tex]

[tex]0.0251t = \ln{2}[/tex]

[tex]t = \frac{\ln{2}}{0.0251}[/tex]

[tex]t = 27.65[/tex]

The doubling time is of 27.65 minutes.

Assume that blood pressure readings are normally distributed with a mean of 115 and a standard deviation of 8. If 100 people are randomly selected, find the probability that their mean blood pressure will be less than 117.
A. 0.0062.
B. 0.8615.
C. 0.8819.
D. 0.9938.

Answers

Answer:

D. 0.9938.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 115 and a standard deviation of 8.

This means that [tex]\mu = 115, \sigma = 8[/tex]

100 people are randomly selected

This means that [tex]n = 100, s = \frac{8}{\sqrt{100}} = 0.8[/tex]

Find the probability that their mean blood pressure will be less than 117.

This is the p-value of Z when X = 117, so:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{117 - 115}{0.8}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a p-value of 0.9938, and thus, the correct answer is given by option D.

Step-by-step explanation:

We can use a ratio to solve

2        3

---- = ------

11        3+x

Using cross products

2(3+x) = 3*11

Distribute

6+2x = 33

Subtract 6

6+2x-6 = 33-6

2x = 27

Divide by 2

2x/2 = 27/2

x = 13.5

Now we have to,

→ solve for x

Then use a ratio to solve,

→ 2/11 = 3/3+x

Now see the further steps,

→ 2(3+x) = 3 × 11

→ 6+2x = 33

→ 2x = 33-6

→ 2x = 27

→ x = 27/2

→ x = 13.5

Hence, 13.5 is value of x.

Answer:

[tex]\boxed {\boxed {\sf (B. \ -4, 3)}}[/tex]

Step-by-step explanation:

We are given 2 equations and asked to solve the system of equations using the substitution method.

The 2 equations are:

[tex]y= -5x-17 \\-3x-3y= 3[/tex]

The first equation is already solved for y, so we can substitute -5x-17 (the expression that y is equal to) into the second equation.

[tex]-3x-3(-5x-17)=3[/tex]

Solve for x by isolating the variable. First, distribute the -3. Multiply each term in parentheses by -3.

[tex]-3x + [ (-3*-5x ) \ + \ (-3* -17)][/tex]

[tex]-3x + [15x + 51]= 3[/tex]

[tex]-3x+15x+51=3[/tex]

Combine like terms. -3x and 15x can be added because both terms contain the variable x.

[tex]12x+51=3[/tex]

51 is being added to 12x. The inverse operation of addition is subtraction. Subtract 51 from both sides of the equation.

[tex]12x+51-51=3-51[/tex]

[tex]12x= -48[/tex]

x is being multiplied by 12. The inverse operation of multiplication is division. Divide both sides by 12.

[tex]\frac {12x}{12}= \frac{-48}{12}[/tex]

[tex]x= -4[/tex]

Now that we have solved for x, we must find y. We know that x is equal to -4, so we can substitute -4 in for x in the first equation.

[tex]y= -5x-17[/tex]

[tex]y= -5(-4)-17[/tex]

Multiply.

[tex]y=20-17[/tex]

Subtract.

[tex]y=3[/tex]

Coordinate points are written as (x, y), so the solution to this system of equations is (-4, 3)

e^(2x).(2 cos(y) - sin(y) y') = 0, where y(0) = 0​

Answers

• 2xy + x ² y' = 0

This DE is exact, since

∂(2xy)/∂y = 2x

∂(x ²)/∂x = 2x

are the same. Then there is a solution of the form f(x, y) = C such that

f/∂x = 2xy   ==>   f(x, y) = x ² y + g(y)

f/∂y = x ² = x ² + dg/dy   ==>   dg/dy = 0   ==>   g(y) = C

==>   f(x, y) = x ² y = C

• sin(x) cos(y) + cos(x) sin(y) y' = 0

is also exact because

∂(sin(x) cos(y))/∂y = -sin(x) sin(y)

∂(cos(x) sin(y))/∂x = -sin(x) sin(y)

Then

f/∂x = sin(x) cos(y)   ==>   f(x, y) = -cos(x) cos(y) + g(y)

f/∂y = cos(x) sin(y) = cos(x) sin(y) + dg/dy   ==>   dg/dy = 0   ==>   g(y) = C

==>   f(x, y) = -cos(x) cos(y) = C

• x ² + y ² - 2xyy' = 0

is not exact:

∂(x ² + y ²)/∂x = 2x

∂(-2xy)/∂y = -2x

So we look for an integrating factor µ(x, y) such that

µ (x ² + y ²) - 2µxyy' = 0

becomes exact, which would require that these be equal:

∂(µ (x ² + y ²))/∂y = (x ² + y ²) ∂µ/∂y + 2µy

∂(-2µxy)/∂x = -2xyµ/∂x - 2µy

Observe that if µ(x, y) = µ(x), then ∂µ/∂y = 0 and ∂µ/∂x = dµ/dx, so we would have

2µy = -2xy dµ/dx - 2µy

==>   -2xy dµ/dx = 4µy

==>   dµ/µ = -2/x dx

Integrating both sides gives

∫ dµ/µ = ∫ -2/x dx   ==>   ln|µ| = -2 ln|x|   ==>   µ = 1/x ²

So in the modified DE, we have

(1 + y ²/x ²) - 2y/x y' = 0

which is now exact and ready to solve, since

∂(1 + y ²/x ²)/∂y = 2y/x ²

∂(-2y/x)/∂x = 2y/x ²

We get

f/∂x = 1 + y ²/x ²   ==>   f(x, y) = x - y ²/x + g(y)

f/∂y = -2y/x = -2y/x + dg/dy   ==>   dg/dy = 0   ==>   g(y) = C

==>   f(x, y) = x - y ²/x = C

• exp(2x) (2 cos(y) - sin(y) y' ) = 0

is exact, since

∂(2 exp(2x) cos(y))/∂y = -2 exp(2x) sin(y)

∂(-exp(2x) sin(y))/∂x = -2 exp(2x) sin(y)

Then

f/∂x = 2 exp(2x) cos(y)   ==>   f(x, y) = exp(2x) cos(y) + g(y)

f/∂y = -exp(2x) sin(y) = -exp(2x) sin(y) + dg/dy   ==>   dg/dy = 0   ==>   g(y) = C

==>   f(x, y) = exp(2x) cos(y) = C

Given that y = 0 when x = 0, we find that

C = exp(0) cos(0) = 1

so that the particular solution is

exp(2x) cos(y) = 1

3x + 3x - 36 = 576

6x = 576 + 36

6x = 612

x = 612 / 6

x = 102

Speed of faster bus, x = 102 km/h

Speed of slower bus, x - 12 = (102 - 12) = 90 km/hr

Does this graph represent a function?

Answers

Answer:

I think it's a function

Step-by-step explanation:

as you can see in the picture curve drawn in a graph represents a function, if every vertical line intersects the curve in at most one point. So I think its a function.

Answer:

yes

Step-by-step explanation:

it's a cubic function having maximum and minimum turning points

it has a point of inflation, y - intercept and x-intercept

In the power function f(x) = -2x3, what is the end
behavior of f(x) as x goes to infinity ?
O f(x) → negative infinity
O f(x) → -2
O f(x) → + 0
O f(x) → 2
O f(x) → infinity

Answers

Answer:

first option f(x) -> negative infinity

Step-by-step explanation:

the other answer is sadly wrong.

there is a "-" in front of the expression.

-2x³ had two parts

-2, which is multiplied to x³

now x³ goes to (positive) infinity for x going to (positive) infinity.

but because this is multiplied by a negative value (-2), all the functional values for positive x are negative.

therefore, the function goes to negative infinity for x going to (positive) infinity.

The end behavior of f(x) as x goes to infinity is (a) f(x) → negative infinity

How to determine the end behavior of the function?

The function is given as:

f(x) = -2x^3

Next, we plot the graph of the function (see attachment)

From the graph, we can see that as the x values increase to infinity, the function values approaches negative infinity

Hence, the end behavior of f(x) as x goes to infinity is (a) f(x) → negative infinity

Step-by-step explanation:

We have two sides; the Adjacent and the Hypotnuse

Meaning we will use Cos

Cos = A/H

Cos X = 16/19

Use the inverse of Cos to find the angle

X = cos-1 (16/19)

X = 0.45499141546

Edgar accumulated $5,000 in credit card debt. If the interest rate is 10% per year and he does not make any payments for 3 years, how much will he owe on this debt in 3 years by compounding continuously?

Answers

the discrete compounding formula is f = p * (1 + r) ^ n

f is the future value

p is the present value

r is the interest rate per time period

n is then number of time periods

in your problem, you are given:

f = what you want to find

p = 5000

r = 30% per year / 100 = .3 per year (percent / 100 = rate).

n = 3 years

if you compound annually, the formula becomes:

f = 5000 * (1 + .3) ^ 3 = 10985

if you compound quarterly, the formula becomes:

f = 5000 * (1 + .3 / 4) ^ (3 * 4) = 11908.898

if you compound monthly, the formula becomes:

f = 5000 * (1 + .3 / 12) ^ (3 * 12) = 12162.67658

if you compound continuously, a different formula is used.

that formula is f = p * e ^ (r * n)

f is the future value

p is the present value

e is the scientific constant of 2.718281828.......

r is the interest rate per time period

n is the number of time periods.

with this formula, you leave the time periods in terms of years.

it will make no difference what time periods and compounding periods you use, the answer will be the same.

most of the time you will just give it the interest rate per year and the number of years.

the reason is as follows:

r * n = .3 * 3 = .9 when giving it rate and time in terms of years.

r * n = .3 / 4 * 3 * 4 = .9 when giving it rate and time in terms of quarters.

r * n = .3 / 12 * 3 * 12 = .9 when giving it rate and time in terms of months.

in your problem, the formula becomes f = 5000 * e ^ (.3 * 3) = 12298.01556.

the more compounding periods per year, the higher the future value.

the highest is when you compound continuously.

this is apparent from the data.
