bogdanovich [222]

Answer:

T.

Step-by-step explanation:

The ordered pair (-2,-1) can also be represented by (x,y). To check the inequality we can substitute the values into the given inequality.

y>-\sqrt{x+11+1}

-1>-\sqrt{-2+11+1}

-1>-\sqrt{10}

-1>-3.1622

After substituting the values, we then have a clear view that -1 is Greater than -3.1622.

Explain how you can tell by looking at a graph if there is a<br> proportional
marissa [1.9K]

You can tell if a graph represents a proportional relationship by identifying the y-intercept, or the point of the line that crosses the y-axis.

If the y-intercept is 0, then the relationship is proportional. This is called a direct relationship.

If the y-intercept is anything other than 0, then the relationship is not proportional. This is called an indirect relationship.

I hope this helps!

Svetach [21]

Answer:

Result is statistically significant.

Step-by-step explanation:

Given that :

Chisquare statistic, χ² = 67.81

Critical value for the distribution, χ²critical = 3.84

α = 0.05

The Decison region :

If χ² statistic > Critical value ; Reject H0 ; this. Eans that result is statistically significant.

Therefore, since, 67.81 > 3.84 ; This means that the result is statistically significant at 0.05
