Can someone help PLSSS
kipiarov [429]

Answer:

Step-by-step explanation:

Area stage = 1/2 h (ab +cd)

Area = 5(14+22)

meeting center Area = 180

room = 25*32 = 800

800-180 = 620 tile

620*$4.90 = $3038

So no not enough money....

Note: even if it was $2999 it still would not be enough because

you have to cut tiles to fit in corners and edges... Just having fun with that comment, the math problems sometimes don't take reality into account (ha ha ha)

Alenkinab [10]

Answer:

The answer is "(-33.9218,-16.0782)\\\\".

Step-by-step explanation:

Calculating the critical value:

Freedom Degree= 7.

The significance level, \alpha= 0.05

Using excel function the critical value:

\to t_{\frac{\alpha}{2} (df)}=t_{\frac{0.05}{2},7}\\\\=T.INV.2T(0.05,7)\\\\=\pm 2.3646\\\\

When 95\% of the confidence intervals for the difference of means:

\to (\bar{x_1}-\bar{x_2}) \pm t_{\frac{\alpha}{2}}\sqrt{\frac{S_1^2}{n_1}+\frac{S_2^2}{n_2}}\\\\=(90-115) \pm 2.3646 \sqrt{\frac{5^2}{8}+\frac{102^2}{9}}\\\\=-25 \pm 2.3646 (3.773077)\\\\=(-33.9218,-16.0782)\\\\

Solve the logarithmic equation rounding to the nearest ten-thousandth<br> 3 log 2x = 4
Rashid [163]
First, divide both sides by 3 to get log2x = 4/3.

Since you know a regular log has base 10, another way to write log2x = 4/3 is 10^(4/3) = 2x.

Then, divide both sides by 2.

x = 10.7722
