413 divided by 14 <br> How do you it?
guajiro [1.7K]
You can either do this on the calculator, or in your head. As its a larger number, it is worth doing it on the calculator.
413/14= 29.5
The alternative method is to list all of the tens multiples, and the smaller multiples when you're getting close to the answer, and this will be able to help you.
14x10= 140
14x20=280
14x30= 420 (which is slightly too big)
14x29= 406 (slightly too small)
14x29.5= 413

Hope this helps :)

BRAINLIEST + POINTS!<br><br> GOOD MATHEMATICIANS HELP ASAP PLEASE
larisa86 [58]

So I went from graph to slope intercept, So you take your x(Fat(g)) and your y(Calories) to solve.

The slope-intercept form for a line with the coordinates of (25,590) and (44,830) is:

y= 12.63x + 274.21

(results are in decimal form, rounded to the nearest 100th)

For Example: y=12.63(125)+274.21

y=1,852.96

If the homogeneity of variance assumption is violated in an independent groups t test, this means _________. the populations fro
Anit [1.1K]

Answer:

the populations from which the samples were drawn have different standard deviations

Step-by-step explanation:

Given that the assumption of homogeneity of variance is the same as the assumption of the independent samples t-test which asserted that all comparison groups possess the same variance

Therefore, if the homogeneity of variance assumption is violated in an independent groups t-test, this means "the populations from which the samples were drawn have different standard deviations."
