▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

The Correct option is ~ B

\boxed{ \boxed{y = 2x - 3}}

\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}

Let's find the slope (m) using points (2 , 1) and (0 , -3)

  • \mathrm{ \dfrac{y2 - y1}{x2 - x1} }

  • \dfrac{1 - ( - 3)}{2 - 0}

  • \dfrac{4}{2}

  • 2

hence, slope = 2

now, by Observing the given graph we can infer that the given line cuts the y - axis at point (0 , -3), so value of y - intercept (c) = - 3

[ y - coordinate of a point when x - coordinate is equal to 0 is the value of y - intercept of a line ]

And, we know the general equation of line in slope - intercept form is ~

  • \boxed{y = mx + c}

now, let's plug the value of slope (m) and y - intercept (c) in the general equation to find the equation of line in slope intercept form ~

  • y = 2x - 3

Which is a graph for the inequality x ≥ 2? HELP I WILL GIVE BRAINIEST
Svetach [21]

Answer:

B

Step-by-step explanation:

x has to be larger than 2 so the arrow has to point to the right.

The value 2 is included, so the start has to be a closed dot.

Explain the purposes of inductive and deductive reasoning in mathematics. Be sure to define both inductive reasoning and deducti
Maru [420]

When it comes to deductive reasoning, it is used to reach a logical solution. You start out with the general statement, or hypothesis, and examine all the possibilities so you can reach the final conclusion.

Inductive reasoning is completely opposite - you focus on specific observations, and then make broad generalizations.

Excel computes a two‑sample confidence interval for the difference in proportions just as well and as easily as Minitab and othe
True [87]

Answer:

See ecplanation below

Step-by-step explanation:

False.

On the Data analysis tool from excel we can conduct the following procedures:

Anova: Single Factor

Anova: Two factor with replication

Anova: Two factor without replication

Correlation

Covariance

Descriptive statistics

Exponential smoothing

F-test Two sample for Variances

Fourier analysis

Histogram

Moving Average

Random number generation

Rank and percentile

Regression

Sampling

t test: Paired two sample for means

t tes: Two sample assuming equal variances

t test: Two sample Assuming Unequal Variances

z test: Two sample for means

And as we can see we don't have an specific procedure just to obtain confidence interval for the difference of proportions. We need to remember that if we select a z test in excel, for example the output will contain the confidence associated to the parameter, but for this case is not too easy obtain a confidence interval for the difference of proportion like on a statistical software as (Minitab, R, SAS, etc) since all of these statistical softwares are elaborated in order to conduct all the possible statistical tests and confidence intervals for parameters of interest.
