Suppose that the area of a square is eight times its perimeter. find the length of a side of the square.

11Alexandr11 [23.1K]

We Know, perimeter of square = 4a
Area of square = a²

Now, A.T.Q,
8*4a = a²
32a = a²
a²/a = 32
a = 32

So, side should be 32

Hope this helps!

The z-score associated with 95% is 1.96. If the sample mean is 200 and the standard deviation is 30, find the upper limit of the

ziro4ka [17]

Answer:

The upper limit of the 95% confidence interval is:

C.I_u = 200 + (58.8/ $\sqrt{n}$ )

Step-by-step explanation:

The formula is given as:

C.I = μ ± Z*σ/ $\sqrt{n}$

The upper limit => C.I_u = μ + Z*σ/ $\sqrt{n}$

The lower limit => C.I_l = μ - Z*σ/ $\sqrt{n}$

The sample size (n) is not stated in the question. Hence, we calculate the upper limit with respect to n.

The upper limit => C.I_u = 200 + 1.96*(30/ $\sqrt{n}$ )

= 200 + (1.96*30)/ $\sqrt{n}$

= 200 + 58.8/ $\sqrt{n}$

What is the slope of the line that passes through (-3, 2) and (1, 2)?

weeeeeb [17]

Answer:

Step-by-step explanation:

Slope of a line which passes through two points (x1,y1) and (x2,y2) is given by:

\frac{y2-y1}{x2-x1}

(x1,y1) = (-3,2)

(x2,y2) = (1,2)

Substituting the values in the equation to determine the slope of the line:

= \frac{2-2}{1-(-3)}

= \frac{0}{4}

So the slope of the given line is 0.

This is intuitively evident as well as the y coordinates of the two given points are the same.
