Solve the equation below for unknown x (x is the money she had initially)

x - 8 - 5 - (x-8-5)/2 = 2

Step-by-step explanation:

Answer:

3x-10y=-41

Step-by-step explanation:

"standard form of the line" is ax+by=c, where a, b, and c are free coefficients

first, we need to find the slope (m) of the line

that is calculated with the formula (y2-y1)/(x2-x1)

we have the points (3,5) and (-7,2)

label the points:

x1=3

y1=5

x2=-7

y2=2

substitute into the equation

m=(2-5)/(-7-3)

m=-3/-10

m=3/10

the slope is 3/10

before we put a line into standard form, we need to put it into another form first-- like slope-intercept form (y=mx+b, where m is the slope and b is the y intercept)

we already know the slope

here's our line so far:

y=3/10x+b

we need to find b; since the line will pass through the points (3,5) and (-7,2) we can use either one of them to find b

let's use (3,5) as an example. Substitute into the equation

5=3/10(3)+b

5=9/10+b

41/10=b

b is 41/10

this is the equation:

y=3/10x+41/10

now we can find the equation in standard form. Subtract 3/10x from both sides

-3/10x+y=41/10

a (the number in front of x cannot be negative OR less than one. First, let's multiply both sides by -1)

3/10x-y=-41/10

multiply both sides by 10 to clear the fraction

3x-10y=-41

^^ is the equation

hope this helps!

The point estimate of the population is 0.415 round to the nearest thousandth as needed the margin error is 0.189.

In statistics, for point estimation, an unknown population parameter (e.g. population mean). More formally, it is applying a point estimator to data to obtain a point estimate.

Point estimation can be contrasted with interval estimation. Such interval estimates are usually confidence intervals for frequentist inference and confidence intervals for Bayesian inference. More generally, point estimators can be contrasted with set estimators. An example is the confidence rate or confidence rate. Point estimators can also be contrasted with distribution estimators. Examples include confidence distributions, randomized estimators, and Bayesian posterior distributions.

Based on the question,

The confidence  interval of Lower bound is 0.226.

The confidence interval of Upper bound is 0.604.

X - E = 0.226.                     --------------------------- (1)

X + E = 0.604                     ---------------------------(2)

Adding equation (1) and (2),

    2X = 0.83

⇒  X = 0.83/2

⇒ X = 0.415

Putting X = 0.415 in equation (1),

0.415 + E = 0.604

⇒ E = 0.604 - 0.415

⇒ E = 0.189

Thus, the point estimate of the population is 0.415 round to the nearest thousandth as needed the margin error is 0.189.

We can use the Central Limit Theorem to solve this problem. According to the theorem, Therefore, the approximate probability that the average salary of the 100 players exceeds ​$1.1 million is 0.

The problem requires us to find the approximate probability that the average salary of a sample of 100 major league players exceeds $1.1 million given that the average salary of professional sports players is $1.6 million with a standard deviation of $0.9 million.

We can use the Central Limit Theorem to solve this problem. According to the theorem, the distribution of sample means will be approximately normal with a mean of the population mean and a standard deviation of the population standard deviation divided by the square root of the sample size. Thus, we can calculate the z-score of the sample mean and use a standard normal distribution table to find the probability.

The z-score can be calculated as follows:

z = (sample mean - population mean) / (population standard deviation / sqrt(sample size))

z = (1.1 - 1.6) / (0.9 / sqrt(100))

z = -5.56

Using a standard normal distribution table, the probability of a z-score less than -5.56 is essentially 0.

Therefore, the approximate probability that the average salary of the 100 players exceeds ​$1.1 million is 0.

The unit rate of gallon to mile is calculated as: 5/6 gallon per mile.

The unit rate between two variables is simply the ratio of the quantity of one variable to the quantity of the other variable, such that the the denominator of the will be equal to exactly 1.

We are given the variables gallons and miles, where 1/4 of a gallon is to 3/10 mile.

The unit rate between these two variables would be an amount of gallons per mile.

Thus, find the unit rate by dividing 1/4 by 3/10:

1/4 ÷ 3/10

= 1/4 × 10/3

= 10/12

= 5/6

The unit rate is therefore, 5/6 gallon per mile.

The error probability is determined by the signal-to-noise ratio (SNR) of the transmitted signal.

The SNR is defined as:

\(SNR = P/N\)

where P is the transmitted power and N is the noise power. To minimize the error probability, the transmitted power should be maximized, so that the SNR is as high as possible. The value of a should therefore be chosen such that the transmitted power is maximized. The transmitted power can be calculated using the following formula:

\(P = a2G\)

Where a is the signal amplitude and G is the gain of the antenna. Therefore, to maximize the transmitted power, the value of a should be chosen such that the product a2G is maximized. This can be done by maximizing either a or G (or both).

The yield to maturity on a simple loan for $1,500 that requires a repayment of $7,500 in five years' time is 37.14%.

Yield to maturity (YTM) is the total return anticipated on a bond or other fixed-interest security if the security is held until it matures. Yield to maturity is considered a long-term bond yield, but is expressed as an annual rate. In this problem, the present value (PV) of the simple loan is $1,500, the future value (FV) is $7,500, the time to maturity is five years, and the interest rate is the yield to maturity (YTM).

Now we will calculate the yield to maturity (YTM) using the formula for the future value of a lump sum:

FV = PV(1 + YTM)n,

where,

FV is the future value,

PV is the present value,

YTM is the yield to maturity, and

n is the number of periods.

Plugging in the given values, we get:

$7,500 = $1,500(1 + YTM)5

Simplifying this equation, we get:

5 = (1 + YTM)5/1,500

Multiplying both sides by 1,500 and taking the fifth root, we get:

1 + YTM = (5/1,500)1/5

Adding -1 to both sides, we get:

YTM = (5/1,500)1/5 - 1

Calculating this value, we get:

YTM = 0.3714 or 37.14%

Therefore, the yield to maturity on a simple loan for $1,500 that requires a repayment of $7,500 in five years' time is 37.14%.

The distance between point G (-3, 5) and point H (6, -3) is approximately 12.04 units.

To find the distance between two points on a coordinate grid, we can use the distance formula, which is derived from the Pythagorean theorem. The formula is:

Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Using this formula, we can calculate the distance between points G and H as follows:

Distance = sqrt((6 - (-3))^2 + (-3 - 5)^2)

= sqrt((6 + 3)^2 + (-3 - 5)^2)

= sqrt(9^2 + (-8)^2)

= sqrt(81 + 64)

= sqrt(145)

The area of shaded portion is 42 cm²

Area of shaded region

Side of square ABCD = 14 cm

Radius of circles with centers A, B, C and D = 14/2 = 7 cm

Area of shaded region = Area of square - Area of four sectors subtending right angle

Area of each of the 4 sectors is equal to each other and is a sector of 90° in a circle of 7 cm radius. So, Area of four sectors will be equal to Area of one complete circle

So,

Area of 4 sectors = \(\pi r^2\)

Area of 4 sectors = \(\frac{22}{7}\) × 7 × 7

Area of 4 sectors = \(154 cm^2\)

Area of square ABCD = (Side)²
