Which ordered pair is the solution?

Mathematics

Answer:

Option d.

Step-by-step explanation:

The given equation is

7x-5=4y-6

We need check which ordered pair is the solution.

Substitute x=2 and y=4 in the above equation.

7(2)-5=4(4)-6

14-5=16-6

9=10

It is a false statement because 9\neq 10.

So, (2,4) is not a solution of given equation.

Substitute x=3 and y=6 in the above equation.

7(3)-5=4(6)-6

21-5=24-6

16=18

It is a false statement because 16\neq 18.

So, (3,6) is not a solution of given equation.

Therefore, option d is correct.

Answer:

d) neither

Step-by-step explanation:

Given equation is 7x - 5 = 4y -6 ...…...... (1)

Substitute x = 2 and y= 4 in equation (1)

 7(2) -5 = 4(4) -6

  9 ≠ 10

a) is not satisfied

Substitute x = 3 and y= 6 in equation (1)

 7(3) -5 = 4(6) -6

  16 ≠ 18

b) is not satisfied

c) is also not satisfied

<u>Final answer</u>:- neither

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
