Answer:

  y -3 = -1/2(x +10)

Step-by-step explanation:

Given a point and a slope, it is reasonable to use the point-slope form of the equation for a line.

  y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Your line has slope m = -1/2 through point (h, k) = (-10, 3). Putting these values into the appropriate form your equation is ...

  y -3 = -1/2(x +10) . . . . point-slope form equation

__

  y = -1/2x -5 +3 . . . . eliminate parentheses, add 3

  y = -1/2x -2 . . . . . . . . . slope-intercept form equation

The Mean Corporation would like to invest in the booming health food industry. It is considering the creation of a health-drink franchise called Goose Juice. The investment department of the Mean Corporation wants to investigate the feasibility of this venture by examining the profits of similar franchises. It believes that the venture will be feasible if an average annual profit of more than $85,000 can be expected from each Goose Juice that is opened. It is known that the annual profits earned by health-drink franchises has a population standard deviation of $8,700.

The Mean Corporation's statisticians would like to construct a hypothesis test for the population mean annual profit earned by health-drink franchises. A random sample of 50 franchises was chosen and their annual profit for the previous financial year was recorded. The mean annual profit for the sample was calculated as $82,441.

The hypotheses that were used by the statisticians were

Null hypothesis: population mean = 81,000, Alternative hypothesis: population mean > 81,000 and the test statistic was found to be 1.29 (to 2 decimal places).

Required:
Calculate the p-value for this test, giving your answer as a decimal to 4 decimal places.

Answers

Answer:

The p-value is approximately 0.9015  

Step-by-step explanation:

The statistic parameters are;

The population mean, μ₀ = $85,000

The population standard deviation, σ = $8,700

The size of the sample, n = 50

The sample mean annual profit, [tex]\bar x[/tex] = $82,441

The null hypothesis, H₀: μ = 81,000

The alternative hypothesis, Hₐ: μ > 81,000

Given that n > 30, a z-test is used

The test statistic ≈ 1.29

Therefore, we have;

[tex]z=\dfrac{\bar{x}-\mu_0 }{\dfrac{\sigma }{\sqrt{n}}} = 1.29[/tex]

From the z-score, the p value for a test statistic of 1.29 = 0.90147 which is 0.9015 after rounding up to 4 decimal places

Why do you think adding and subtracting polynomial expressions is like adding and subtracting
expressions?

Answers

Answer:

Polynomials are closed under addition and subtraction, which is fancy mathspeak that means that whenever we add or subtract two polynomials, we always get another polynomial. In that way, they behave a lot like the numbers you're probably already familiar with. Adding and subtracting:

Two integers gives you another integerTwo rational numbers gives you another rational numberTwo real numbers gives you another real number

And it works the same with polynomials!

Hello the reference related to your question is missing attached below is the reference

answer : p ( x - y ≥ 1 ) = 0.0019

Step-by-step explanation:

Assuming 'X' and 'Y' are independent random samples

X : mean value = [tex]U_{1}[/tex] , variance = 0.4 /10 = 0.04

Y : mean value = [tex]U_{2}[/tex] , variance = 0.8/10 = 0.08

since the values are independent

V [ X - Y ] = V [ X ] + V [Y ] = 0.04 + 0.08 = 0.12

Determine the probability that the sample mean for species A exceeds the sample mean for species B by at least 1 unit

P ( x - y ≥ 1 ) = 0.0019

A box contains 1111 large marbles and 1111 small marbles. Each marble is either green or white. 66 of the large marbles are green, and 44 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is small or green? Express your answer as a fraction or a decimal number rounded to four decimal places.

Answers

Answer:

0.7727 = 77.27% probability that it is small or green

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

11 large + 11 small = 22 total marbles = 22 total outcomes

11 small marbles  + 6 green large marbles = 17 desired outcomes.

What is the probability that it is small or green?

[tex]p = \frac{17}{22} = 0.7727[/tex]

0.7727 = 77.27% probability that it is small or green

We have the difference of squares

Now replace x with (5a -3b)

(5a -3b -5a) ( 5a -3b +5a)

Combine like terms

Answer:

(5a-3b)²-25a²

simplify the above expression, then tell me what rule you used, (product rule, power rule, quotient rule.) then explain how you did the problem

Answers

Answer:

Step-by-step explanation:

You have to use the power rule for this. The way I teach my Algebra 1 students to do this is take everything inside the parenthesis and put it into its own set of parenthesis, and then raise each one to the outside power. One thing at a time makes it not so overwhelming. Like this:

[tex](4)^2(x^5)^2(y^3)^2[/tex]

Now follow the power rule. Multiply the power of each element in the parenthesis by the 2 outside.

[tex](4^1)^2=4^2=16[/tex], then [tex](x^5)^2=x^{10[/tex], and finally, [tex](y^3)^2=y^6[/tex].

Now put it all together to get:
