3 (2d-1) 2d= 4(d-2) + 5

Answers

Answer:

The answer will be 0=0. This means that the equation will always be true.

Final answer:

The question is a quadratic equation that can be solved by first simplifying, setting to equal zero, and finally using a method like factoring, completing the square, or the quadratic formula.

Explanation:

To solve the equation 3 (2d-1) 2d= 4(d-2) + 5, firstly, you'll need to distribute the expressions inside the brackets on both sides: 6d² - 3d = 4d - 8 + 5. Simplify to get 6d² - 3d = 4d - 3.

Next, set the equation to equal zero: 6d² - 3d - 4d +3 = 0, which simplifies further to 6d² - 7d + 3 = 0.

Now, you can solve this quadratic equation either by factoring, completing the square or using the quadratic formula (if it's difficult to factor).

Which of the following ratios is equivalent to 12/20? Answers A. 3/10 B. 5:3 c. 120 to 200 D. 60/80

Answers

A is 3/10 , if we multiply top and bottom by 4 we get 12/40 , which is not equivalent to 12/20.

B is 5:3 , it cannot be equivalent to 12/20.

C is 120 to 200 , if we divide both numerator and denominator by 10 we get 12/20, So option C is correct.

D is 60/80 , if we divide both numerator and denominator by 5, we get 12/16 , which is not equivalent to 12/20.

Hence option C is the correct answer.

12 : 20
12 x 10 : 20 x 10
120 : 200 (Answer C)

The linear equation of the initial (red ) incline would be y = __x +__

Answers

Answer:

$y=\underline {1.5}x+\underline 0$

Step-by-step explanation:

From the graph,

The initial red incline is a straight line passing through the origin.

So, a straight line passing through the origin is of the form:

$y=mx+0$

Where, 'm' is the slope.

Now, the slope of a given as the change in y value to change in x value.

Consider the two end points of the red line (0, 0) and (4, 6).

The slope with two points $(x_1,y_1)\ and\ (x_2,y_2)$ on the line is given as:

$m=((y_2-y_1))/((x_2-x_1))$

Plug in $x_1=0,y_1=0,x_2=4,y_2=6$ . Therefore, slope is:

$m=(6-0)/(4-0)\nm=(6)/(4)=1.5$

Hence, the equation of the initial red incline is:

$y=\underline {1.5}x+\underline 0$

The conclusion for a test statistic is either to reject the null hypothesis" or to "not reject the null hypothesis". A good statistician NEVER "accepts the alternate hypothesis". Explain the reason you either "reject the null hypothesis" or "do not reject the null hypothesis". Explanation should be at least 5-7 sentences."

Answers

Answer:

Step-by-step explanation:

Hello!

The null hypothesis is the commonly accepted fact, if you were to make an experiment, you'll state in the null hypothesis what is already known of your population, another way to see it is that the null hypothesis has the "no change" statement. When doing a statistic test you seek to nullify the null hypothesis to replace it with the alternative hypothesis, i.e., the objective of any hypothesis test is to invalidate this hypothesis not to prove the alternative hypothesis right.

In short words, you work to annulate what is accepted knowledge and not to prove what you think happens.
