PtichkaEL [24]
Or this question you should know that:
1/3 = (1*4)/(3*4) = 4/12 
and 
2/3 = (2*4)/(3*4) = 8/12 
so you can see that 7/12 is greater than 4/12 which is 1/3 and less than 8/12 which is 2/3 :))))

The magnitude of the resultant vector shown is _____.
Flura [38]

Answer:

  2√3

Step-by-step explanation:

You recognize this as a 30°-60°-90° triangle, so you know the hypotenuse (R) is twice the length of the shortest side (√3).

The magnitude of R is 2√3.

_____

In case you haven't memorized the ratios for a 30°-60°-90° triangle, you can use trigonometry and the fact that ...

  Sin = Opposite/Hypotenuse

  sin(30°) = √3/R

  R = √3/sin(30°) = √3/(1/2) = 2√3

Of course, doing this on your calculator will give a numerical answer, which you may not want.

Help me with this question please
mojhsa [17]

Step-by-step explanation:

so, he will not wear any pants ? socks ? not to mention underwear ?

anyway, we have to deduct the $35 for the shoes, as he is seemingly buying them in any case.

so, we are left with 100 - 35 = $65 for shirts.

as one shirt costs $15, we need to see how often 15 fits into 65, as that is the answer how many shirts he can buy for this money.

65 / 15 = 4.333333333...

since he cannot buy a part shirt, we can only rely on the integer part of the calculation.

so, he can buy 4 shirts and will have $5 left.

vovikov84 [41]

Answer:

D. If the​ P-value is​ large, reject the null hypothesis of no interaction. Conclude that there is an interaction effect.

Step-by-step explanation:

If p value is smaller than significant level(5% or 1%), then reject the null hypothesis.

From the given information about two way ANOVA, First 3 are true statements based on decision rule.

4th statement is false, becasue p value is larger, then decision is to fail the null hypothesis and conclude that there is no interaction between them
