The coordinates for three points of a rectangle are (2, 6) (2, 9) and (8, 6). What is the coordinate for the fourth point in the

saw5 [17]

Answer:

(8,9)

Step-by-step explanation:

Given

$A = (2,6)$

$B = (2,9)$

$C = (8,6)$

Required

Determine the 4th point

The coordinate point of a horizontal or a vertical rectangle is given as:

(x1,y1), (x2,y2), (x3,y3), (x4,y4)

Where:

$x_1 = x_2$ $x_3 = x_4$ $y_1 = y_3$ $y_2 = y_4$

So, we have:

$A = (2,6)$ --- $(x_1.y_1)$

$B = (2,9)$ ---- $(x_2.y_2)$

$C = (8,6)$ ---- $(x_3,y_3)$

Using the above equations:

$x_3 = x_4$ $=8$

$y_2 = y_4$ $= 9$

Hence, the coordinate of the 4th point is:

$(x_4,y_4) = (8,9)$

A study of the impact of executive networking on firm performance measured firm performance as annual return on equity (ROE), r

vova2212 [387]

Answer:

The value of ROE that will be exceeded by 78% of the firms is -1.77%.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma,$ the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

The mean ROE for the firms studied was 14.93% and the standard deviation was 21.74%. This means that $\mu = 0.1493, \sigma = 0.2174$

What value of ROE will be exceeded by 78% of the firms?

This is the value of X when Z has a pvalue of 1-0.78 = 0.22.

This is $Z = -0.77$

So:

$Z = \frac{X - \mu}{\sigma}$

$-0.77 = \frac{X - 0.1493}{0.2174}$

$X - 0.1493 = -0.77*0.2174$

$X = -0.0177$

The value of ROE that will be exceeded by 78% of the firms is -1.77%.

Iris is a botanist who works for a garden that many tourists visit. the function f(s) = 2s + 25 represents the number of flowers

7nadin3 [17]

A function is said to be a composite function when a function is written in another function. The composite function that represents the number of flowers is f(w)=50w+25 and the number of flowers for 30 weeks is 1525.

Given that:

f(s)=2s+25

s(w)=25w

The number of flowers to bloom over w weeks is calculated using the following composite function: f(w)

f(s)=2s+25

Replace s with s(w)

f(s(w))=2(s(w))+25

Substitute (w)=25w

f(s(w))=2(25w)+25

f(s(w))=50w+25

Hence:

f(w)=50w+25

The units of the measurement of f(w) are flowers

The number of flowers for 30 weeks means:

w=30

So, we have:

f(w)=50w+25

f(30)=50 * 30+25

f(30)=1525

Hence, the number of flowers for 30 weeks is 1525
