The equation have the same solution as 2.3p – 10.1 = 6.49p – 4 and 230p – 1010 = 650p – 400 – p

Given: 2.3p – 10.1 = 6.5p – 4 – 0.01p.

Using this given property, let's write the equation

We can subtract like terms (6.5p– 0.01p = 6.49p) to get:

2.3p – 10.1 = 6.5p – 0.01p – 4

2.3p – 10.1 = 6.49p – 4

Also, we can multiply both sides of the algebraic equation by 100:

(2.3p – 10.1) x 100 = (6.5p – 4 – 0.01p) x 100

230p – 1010 = 650p – 400 – p

Therefore, the equations have the same solution as 2.3p – 10.1 = 6.49p – 4 and 230p – 1010 = 650p – 400 – p. The 2nd and 3rd options are the answers

Step-by-step explanation:

Definitions

Note:  Assume that each square on the given graphs is 1 unit.

As there are arrows at both endpoints of the curve, the domain of the function is unrestricted.

The curve has a maximum point at (2, 4) and continues indefinitely towards negative infinity at both endpoints.

Therefore, the range of the function is restricted.

As there are arrows at both endpoints of the function, the domain is unrestricted.

The function has a minimum point at y = 3.

When x > -2, the line continues indefinitely at y = 3.

When x < -2, the line continues indefinitely towards infinity.

Therefore, the range of the function is restricted.

The domain of the function is restricted since there is a closed circle at one endpoint: (-2, -3).  When x > -2, the line continues indefinitely towards infinity.

The function has a minimum point at (-2, -3). As x continues towards infinity, so does y.

Therefore, the range of the function is restricted.

Zach's investment is $100,000.

A ratio shows us the number of times a number contains another number.

Given that Zach, Kolby, and Peyton are investing a total of $350,000 to open a coffee shop. And their investments are in the ratio 1:2:0.5, respectively.
Therefore, Zach, Kolby, and Peyton's investment can be written as  1x, 2x, and 0.5x, respectively.

Now, the total sum of the investment of the three can be written as,

Zach's investment + Kolby's investment + Peyton's investment = $350,000

1x + 2x + 0.5x = $350,000

3.5x = $350,000

x = $350,000 / 3.5

x = 100,000

The equation of the line is : y = -1x + 3

What is Equation of line?

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

Given,

3x + 3y = 2

3y = -3x + 2

y = -x + 2/3

Comparing it with

y = mx + c

we get,

m = -1

Now, let the equation of line be

y = mx + c

where, m = -1

Now we have to check for point (0,0) that it satisfies

0 = -1(0) + c

c = 0

So, the equation of line will be y = -1x

Now, let y = mx + c be the equation of line of point (-3, 6) should satisfy]

6 = -1(-3) + c

6 = 3 + c

c = 6 - 3

c = 3

So the equation of line is y = -1x + 3

Hence, The equation of the line is  y = -1x + 3

Answer:  7 4/10 + 2/10 = 38/5 = 7 3/5 = 7.6

Answer Overall : 38/5

Step-by-step explanation:  Conversion a mixed number 7 4/10 to a improper fraction: 7 4/10 = 7 4/10 = 7 · 10 + 4/10= 70 + 4/10= 74/10

To find a new numerator:

a) Multiply the whole number 7 by the denominator 10. Whole number 7 equally 7 * 10/10 = 70/10

b) Add the answer from previous step 70 to the numerator 4. New numerator is 70 + 4 = 74

c) Write a previous answer (new numerator 74) over the denominator 10.

Seven and four tenths is seventy-four tenths

Add: 74/10 + 2/10 = 74 + 2/10 = 76/10 = 2 · 38/2 · 5 = 38/5

The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 10) = 10. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 10 = 100. In the following intermediate step, cancel by a common factor of 2 gives 38/5.

In other words - seventy-four tenths plus two tenths is thirty-eight fifths.

First convert the mixed number to a fraction by multiplying 7 by 10 and adding 4

add them together but DONT add the denominators

These numbers can be simplified by 2 so the final answer is:

At 95% confidence, the z critical value is roughly z = 1.96

You would use a reference table or calculator to determine this value. Unfortunately it's not something that can be easily/quickly found by hand.

If we're trying to estimate the population mean (mu), then we'll use this margin of error formula

E = z*sigma/sqrt(n)

Or if we want to estimate the population proportion (p), then we use this formula

E = z*sqrt(phat*(1-phat)/n)

The confidence interval then spans from (pointEstimate)-E to (pointEstimate)+E. Where "pointEstimate" represents either xbar or phat depending on the context. Other point estimates are possible. We're focusing on these two for now.

xbar estimates mu

phat estimates p

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

An example problem:

A manager at a soda bottling plant wants to know if the contents of the cans are 20 fluid ounces (fl oz) or not. Through past observations, the manager has noted the population standard deviation (sigma) is 1.72 fl oz.

The manager gathers a random sample of 50 cans to test their contents. They find the sample mean is 18 fl oz. Conduct a hypothesis test using a confidence interval at 95% confidence to see if the cans really do have 20 fl oz of drink in them or not.

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

Solution:

Null Hypothesis: mu = 20

Alternate Hypothesis: mu ≠ 20

This is a two-tailed test.

E = margin of error

E = z*sigma/sqrt(n)

E = 1.96*1.72/sqrt(50)

E = 0.47676

L = lower boundary of confidence interval

L = xbar - E

L = 18 - 0.47676

L = 17.52324

L = 17.52

U = upper boundary of confidence interval

U = xbar + E

U = 18 + 0.47676

U = 18.47676

U = 18.48

The 95% confidence interval is approximately (17.52, 18.48)

This is equivalent to writing 17.52 < mu < 18.48 in which we are 95% confidence in saying mu is between those endpoints.

But wait, the hypothesized mu = 20 is not in the interval 17.52 < mu < 18.48, which indicates we must reject the null hypothesis and accept the alternate hypothesis.  

The soda cans do not have 20 fl oz of drink. It appears they have slightly less than 20 fl oz.

The required equation  can be used to determine the pounds of laundry the customer brought in is A. 0.61x + 28.00 = 41.42

An equation is a mathematical expression that shows the relationship between two variables.

To find the given equation,

Let x be the number of pounds of clothes washed and folded at the laundromat.

Given that the laundromat will wash and fold clothes at $0.61 per pound for those customers with a laundry service, the total amount paid for the number of poundsof clothes is P = rate × number of pounds = $0.61 × x = 0.61x

Also, the laundromat has a wash-and-fold service for a monthly fee of $28.00.

So, the total amount paid is T = P + $28.00 = $0.61x + $28.00

Now, since one customer paid $41.42 in total for the month, since this is the total amount paid, then T = $41.42

So, $0.61x + $28.00 = $41.42
