Answer:

The answer is 3rd point.

Step-by-step explanation:

You can simplify the bracket first,

(-1/2×√2)

= (-1/2×√2)

(-6√18)

= -6(√2×9)

= -6×3√2

= -18√2

Finally, you can expand it :

(-1/2√2)(-18√2)

= (-1/2 × -18)(√2 × √2)

= 9 × 2

= 18

Log14/3 +log11/5-log22/15=log
Tamiku [17]

Answer:

log7

Step-by-step explanation:

when adding logs, apply the log rule: \log _a\left(x\right)+\log _a\left(y\right)=\log _a\left(xy\right)

∴  \log\left(\frac{14}{3}\right)+\log\left(\frac{11}{5}\right)=\log\left(\frac{14}{3}\cdot \frac{11}{5}\right)

when subtracting logs, apply the log rule: \log _a\left(x\right)\:-\:\log _a\left(y\right)=\log _a\left(\frac{x}{y}\right)

\log\left(\frac{14}{3}\cdot \frac{11}{5}\right)-\log\left(\frac{22}{15}\right)=\log\left(\frac{\frac{14}{3}\cdot \frac{11}{5}}{\frac{22}{15}}\right)\\\\=\log\left(7\right)

A sheet of paper is 8.5 in X 11 inches if you cut 2 in squared from each corner what is the area if the paper
IceJOKER [234]
A=length x height. First we want to know the area of the original sheet of paper. 8.5 x 11= 93.5 inches squared. Then we take two squares with side length 2 inches. The area of each of these squares is 2 x 2, or 4 inches. Since there are two, the total area we take away is 8 inches. We subtract 8 inches from 93.5 since we took it away, and the final area of the paper is 85.5 inches^{2}

Hope this helped!

Refer to the accompanying TI-83/84 Plus calculator display of a 95% confidence interval. The sample display results from using a
nikklg [1K]

Answer:

The confidence interval is 22.805

Step-by-step explanation:

We have given,

The Z interval (23.305,25.075)  

Mean \bar{x}=23.69

Sample n=30

To find : The confidence interval?

Solution :

We know, The confidence interval is in the format of

\bar{x}-E

E denotes the margin of error,

E=\frac{U-L}{2}

Where, U is the upper limit U=25.075

L is the lower limit L=23.305

E=\frac{25.075-23.305}{2}

E=\frac{1.77}{2}

E=0.885

Substitute the value of E and \bar{x} in the formula,

23.69-0.885

22.805

Therefore, The confidence interval is 22.805
