A system of equations consists of a line s of the equation y = x - 5 that is graphed in orange, and a line t that passes through
Zarrin [17]

ANSWER

x =  4

and

y =   - 1

EXPLANATION

Line s has equation:

y=x-5

And line t has equation:

y =  -  \frac{3}{4}x  + 2

We equate the two equations to get:

x - 5 =  -  \frac{3}{4} x + 2

Multiply through by 4

4x - 20  =  -  \frac{3}{4} x \times 4 + 2 \times 4

4x - 20  =  - 3 x  + 8

4x + 3x   =  8 + 20

7x=28

x =  \frac{28}{7}  = 4

y =  4  - 5 =  - 1

If the distribution is really (5.43,0.54)
defon

Answer:

0.7486 = 74.86% observations would be less than 5.79

Step-by-step explanation:

I suppose there was a small typing mistake, so i am going to use the distribution as N (5.43,0.54)

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.

The general format of the normal distribution is:

N(mean, standard deviation)

Which means that:

\mu = 5.43, \sigma = 0.54

What proportion of observations would be less than 5.79?

This is the pvalue of Z when X = 5.79. So

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

Z = \frac{5.79 - 5.43}{0.54}

Z = 0.67

Z = 0.67 has a pvalue of 0.7486

0.7486 = 74.86% observations would be less than 5.79

Given: PRST square
yuradex [85]
There is no difficulty in this problem until you construct the figures. How can we do it is shown in the attached picture. After drawing PRST, from the point P, we can draw PMKD and later we can complete PMCT as a result. From this picture, we can see that the side of PMCT is also a. Then, the area of this square is A=a^{2}
