Answer:

34 miles

Step-by-step explanation:

You just need to add her 9 then the extra 25 miles to find the starting set of miles

Answer:

Elisa ran 34 miles

Step-by-step explanation:

Shawna ran 9 miles which is 25 less than Elisa

Elisa ran 25 miles more than Shawna

equation:

9 = x - 25

add 25 on both sides:

9 + 25 = x - 25 + 25

34 = x

Elisa ran 34 miles

The value of x should be less than 3.5.

Given that sides of a triangle are x cm, x + 3 cm and 10 cm. We need to find the lowest value of x,

Using the triangle inequality theorem,

The triangle inequality theorem states that, in a triangle, the sum of lengths of any two sides is greater than the length of the third side.

So,

x + x + 3 > 10

2x + 3 > 10

2x < 7

x < 3.5

Hence the value of x should be less than 3.5.

The slope of the line shown in the graph is __2/3__

and the y-intercept of the line is __6___

The general linear equation is written as follows:

y = ax + b

Where a is the slope and b is the y-intercept.

On the graph we can see that the y-intercept is y = 6, then we can write the line as:

y = ax + 6

The line also passes through the point (-9, 0), replacing these values in the line we will get:

0 = a*-9 + 6

9a = 6

a = 6/9

a = 2/3

That is the slope.

Step-by-step explanation:

squaring both side

(18√8-8√18)^2=(√n)^2

(18√8)^2+(8√18)^2-(2)(8√18)(18√8)=n

after solving it we will get

3744-3456=n

n=288

=====================================================

Explanation:

Simplify the first part of the left side

\(18\sqrt{8} = 18\sqrt{4*2}\\\\18\sqrt{8} = 18\sqrt{4}*\sqrt{2}\\\\18\sqrt{8} = 18*2*\sqrt{2}\\\\18\sqrt{8} = 36\sqrt{2}\)

And do the same for the second part of the left side

\(8\sqrt{18} = 8\sqrt{9*2}\\\\8\sqrt{18} = 8\sqrt{9}*\sqrt{2}\\\\8\sqrt{18} = 8*3*\sqrt{2}\\\\8\sqrt{18} = 24\sqrt{2}\)

For each simplification, you are trying to factor the stuff under the square root so that you pull out the largest perfect square factor possible.

-------------------------

The original equation \(18\sqrt{8}-8\sqrt{18} = \sqrt{n}\) turns into \(36\sqrt{2}-24\sqrt{2} = \sqrt{n}\)

We have the common factor of \(\sqrt{2}\) so we can combine like terms on the left side ending up with \(12\sqrt{2}\)

-------------------------

So,

\(18\sqrt{8}-8\sqrt{18} = \sqrt{n}\\\\36\sqrt{2}-24\sqrt{2} = \sqrt{n}\\\\12\sqrt{2} = \sqrt{n}\\\\\sqrt{n} = 12\sqrt{2}\\\\\left(\sqrt{n}\right)^2 = \left(12\sqrt{2}\right)^2\\\\n = 288\)

Yes it is possible to express \(18\sqrt{8}-8\sqrt{18}\) as multiples of the same square root. In this case, we can express the left hand side of the original equation as 12 multiples of \(\sqrt{2}\)

Answer:

Based on the confidence interval, Sheldon's claim is plausible

Step-by-step explanation:

The number of customers in the sample, n = 620 customers

The number of customers that replied that they had moved at least once in the last five years = 201 (32.4%)

The 90% confidence interval for the sample = (0.293, 0.355)

Let 'p' represent the proportion of all customers who have moved in the past five years

The proportion of customers Sheldon claimed have moved in the past five years, p > 1 in 4 (0.25)

The proportion Zachary urges Sheldon to claim is, p > 1 in 3 (0.\(\overline 3\))

Given that the lower estimate of the confidence interval is 0.293 (>0.25) and upper bound of the confidence interval is 0.355 (> 0.\(\overline 3\)), and that 0.26 in also more than 1 in 4 but less than 0.293, but however that 0.293 which is within the 90% confidence interval is less than 0.\(\overline 3\) or 1 in 3, as opposed to what Zachary urges Sheldon to claim, Sheldon's claim is more plausible.

Answer:

\(y=\frac{7-3x}{j}\)

Step-by-step explanation:

First, subtract 3x. This leaves you with jy=7-3x. Then, divide by j, leaving you with \(y=\frac{7-3x}{j}\) .

Given,

the coordinates of the point is P(-4, -1) and N(1, -8).

Required

The distance between the point P and N.

The distance between the point P and N.

Hence, the distance between the points is sqrt(74).

To find the number of payments needed to reach the retirement goal of $730,000, we can use the formula for the future value of an ordinary annuity:

FV = P * ((1 + r)^n - 1) / r

Where:

FV = Future value (goal amount) = $730,000

P = Monthly payment = $900

r = Annual interest rate = 11.5% = 0.115 (expressed as a decimal)

n = Number of payments (unknown)

Plugging in the given values into the formula, we can solve for n:

$730,000 = $900 * ((1 + 0.115)^n - 1) / 0.115

Now, let's solve for n. First, we'll simplify the equation:

730,000 * 0.115 = 900 * ((1 + 0.115)^n - 1)

84,050 = (1.115^n - 1) * 900

Divide both sides by 900:

93.39 = 1.115^n - 1

Add 1 to both sides:

94.39 = 1.115^n

Now, take the logarithm of both sides using the natural logarithm (ln):

ln(94.39) = ln(1.115^n)

Using the logarithmic property ln(a^b) = b * ln(a), we can simplify further:

ln(94.39) = n * ln(1.115)

Divide both sides by ln(1.115):

n = ln(94.39) / ln(1.115)

Using a calculator, we can find:

n ≈ 280.64

Since the number of payments represents the number of months, we round up to the nearest whole number:

n = 281

Therefore, the young professional will need to make 281 monthly payments to reach her retirement goal of $730,000.

Answer:

The probability of rolling a 6 on a die is 1/6

Step-by-step explanation:

There are 6 faces on a die which means 6 equal chances of rolling on a specific face

Step-by-step explanation:

a slope-intercept form :

y = ax + b

"a" is the slope, "b" is the y-intercept (the y-value when x = 0).

the slope is the ratio (y coordinate change / x coordinate change) when moving from on point on the line to another.

"b" we can read off the graph : when x = 0, then y = -5.

so, b = -5.

for the slope let's pick 2 points. your teacher has kindly marked already points with integer coordinates.

so, I pick (3, 1) and (4, 3).

x changes by +1 (from 3 to 4).

y changes by +2 (from 1 to 3).

so, the slope is

+2/+1 = 2/1 = 2

the equation is

y = 2x - 5

Answer: y=2x-5

Step-by-step explanation:

Choose two points on the graph: (0,-5) and (3,1)

The straight line equation is: y=mx+b

1)

             \(\displaystyle\\\boxed {The\ slope\ m\ =\frac{y_2-y_1}{x_2-x_1} }\)

\(\displaystyle\\x_1=0\ \ \ \ \ x_2=3 \ \ \ \ y_1=-5\ \ \ \ y_2=1\\\\ Hence,\\\\m=\frac{1-(-5)}{3-0} \\\\m=\frac{1+5}{3} \\\\m=\frac{6}{3} \\\\m=2\\\\Thus,\ y=2x+b\ \ \ \ \ (1)\)

2)

To determine the coefficient b, take any of the two points,

for example, (0,-5), that is, x=0 y=5

Substitute these values into formula (1):

\(-5=2*0+b\\-5=0+b\\-5=b\\Thus,\ b=-5\)

The result is y=2x-5

The statement lim n→∞ |Xₙ|/n ≤ C almost surely is equivalent to E|X| < ∞.

To show that lim n→∞ |Xₙ|/n ≤ C almost surely (where C > 0), if and only if E|X| < ∞, we can use the Borel-Cantelli Lemma and the Law of Large Numbers.

1. First, let's assume that lim n→∞ |Xₙ|/n ≤ C almost surely.
  - This means that the sequence of random variables |Xₙ|/n converges almost surely to a limit less than or equal to C.
  - By the Borel-Cantelli Lemma, if the sum of the probabilities of infinitely many events is finite, then the probability of those events occurring is zero.
  - Let Aₙ be the event { |Xₙ|/n > C }.
  - Since the limit of |Xₙ|/n is less than or equal to C almost surely, it implies that the probability of Aₙ occurring infinitely often is zero.
  - Therefore, the sum of the probabilities of Aₙ is finite.
  - Now, we can calculate the expected value of |X| using the definition of expectation: E|X| = ∫ |x| f(x) dx, where f(x) is the probability density function of X.
  - By the monotonicity property of the integral, we have: E|X| = ∫ 0∞ P(|X| > t) dt.
  - By the definition of Aₙ, we have: P(|Xₙ|/n > C) = P(|Xₙ| > nC).
  - Therefore, the sum of the probabilities P(|Xₙ| > nC) is finite, which implies that the expected value E|X| is finite.

2. Now, let's assume that E|X| < ∞.
  - By the Law of Large Numbers, we know that Xₙ/n converges in probability to E(X).
  - Since Xₙ/n converges in probability, it also converges almost surely to the same limit.
  - Therefore, lim n→∞ |Xₙ|/n = lim n→∞ |Xₙ|/n ≤ E|X|/n = 0 almost surely.
  - Since lim n→∞ |Xₙ|/n ≤ 0 almost surely, we can multiply both sides by -1 to obtain lim n→∞ |Xₙ|/n ≤ 0 almost surely.
  - By adding C to both sides, we get lim n→∞ |Xₙ|/n ≤ C almost surely.

In conclusion, the statement lim n→∞ |Xₙ|/n ≤ C almost surely is equivalent to E|X| < ∞.

Answer:

Pat earnings = $181

Ally earnings = $362

Julie earnings = $452

Step-by-step explanation:

Let

Pat earnings = x

Ally earnings = 2x

Julie earnings = 2x + 90

Total earnings = $995

Total earnings = Pat earnings + Ally earnings + Julie earnings

995 = x + 2x + (2x + 90)

995 = 3x + 2x + 90

995 = 5x + 90

995 - 90 = 5x

905 = 5x

x = 905/5

x = 181

Pat earnings = x = $181

Ally earnings = 2x

= 2(181)

= $362

Julie earnings = 2x + 90

= 2(181) + 90

= 362 + 90

= $452

The greatest number of people that William and Debra may invite and still stay within their budget is 63.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Since William and Debra have budgeted $2,500 for their reception. Therefore, their total expenses should be equal to the total expenses in the reception.

Budget = Total expenses

Budget = Reception hall Cleanup charge + $38 per person fee

Let the number of people invited to the party be represented by x,

$2,500 = $100 + $38(x)

2500 = 100 + 38x

2500 - 100 = 38x

2400 = 38x

x = 2400 / 38

x = 63.157 ≈ 63

Hence, the greatest number of people that William and Debra may invite and still stay within their budget is 63.

So the first thing that you'll have to recognize is that  the interior angles of a triangle add to 180°

Next, note that the angle that is given as 5y -23 is also the same angle as the inside of the triangle,  as well as the angle it's written on.

recognizing both of these let's  you write this.

180 = 2x+13 + 47 + 5y - 23

this doesn't help us too much because there are two unknowns and only one equation.  we would need two equations to solve this :(  

but.....

now note, that the angle  3x  and  5y - 23 are also equal.  Assuming that the lines are parallel that look parallel. I think for this problem we can assume that they are.

now revise the problem

180 = 2x+13 +47 +3x

now  use your algebra skillz

180 = 5x 60

180-60 = 5x

120 = 5x

120/5 = 5x/5

24 = x

now plug x into the earlier equation

180 = 2x+13 + 47 + 5y - 23

180 = 2(24) + 13 + 47 +5y - 23

180 = 48 + 13 + 47 +5y -23

180 = 109 - 23 + 5y

180 = 85 + 5y

180 - 85 = 5y

Examples of permutation matrices are the identity matrices with a permutation in rows. Permutation matrices are invertible and the inverse is a permutation matrix as well.

A permutation matrix is a square matrix which contains exactly one 1 in each row and all other entries 0.

So a permutation matrix can be obtained by rearranging the rows or columns of an identity matrix. Identity matrix is also a permutation matrix with entry 1 exactly once in each row and all other entries 0.

Example of a permutation matrix:

\(\left[\begin{array}{ccc}1&0&0\\0&0&1\\0&1&0\end{array}\right]\)

A permutation matrix is invertible because an identity matrix is invertible [since det(I) = 1] and a permutation matrix is just got by exchanging rows or columns which does not change its determinant. So the determinant of a permutation matrix ≠ 0 and hence invertible.

The inverse of a permutation matrix is its transpose itself. The transpose is again a permutation matrix.
