EleoNora [17]

Answer:

A. the reduction of variance

Step-by-step explanation:

If the p bakue gets smaller, the smaller the p- value the stronger the evidence that we can or we should totally reject and not accept the null hypothesis.

Id the p value is lower, the result is trumpeted as significant, but if higher,it is not significant.

So Smaller p-values indicate more evidence in support of the the reduction of variance

Solve this system of linear equations without graphing:<br> 5x + 4y= 8<br> 10x – 4y = 46
n200080 [17]

Answer: x=3.6; y=-2.5

Step-by-step explanation:

To solve this pair of equations, we can use elimination method.

5x+4y=8

10x-4y=46

Add both equations together to cancel out 4y.

15x=54               [divide both sides by 15]

x=3.6

Now that we know x, we can plug it back into any equation to find y.

5(3.6)+4y=8       [multiply]

18+4y=8             [subtract both sides by 18]

4y=-10                [divide both sides by 4]

y=-2.5

Now, we have x=3.6 and y=-2.5.

Identify the slope and the intercept for the following inequality -2×-y​
sergij07 [2.7K]

\Huge{\textbf{\textsf{{\color{navy}{ᴀɴ}}{\purple{ᴡs}}{\pink{ᴇʀ}}{\color{pink}{:}}}}}

It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
