Answer:

The two odd numbers are 15 and 17

Step-by-step explanation:

Given

<em>Let the odd numbers be represented with x and y</em>

<em>Let x be the greater number</em>

<em></em> $x + 5y = 92$ <em></em>

<em></em>

<em>Required</em>

Find x and y

Since x and y are consecutive odd numbers and x is greater, then

$x = y + 2$

Substitute y + 2 for x in $x + 5y = 92$ <em></em>

<em></em> $y + 2 + 5y = 92$ <em></em>

<em></em>

Collect Like Terms

<em></em> $y + 5y = 92 - 2$ <em></em>

<em></em> $6y = 90$ <em></em>

Divide both sides by 6

$\frac{6y}{6} = \frac{90}{6}$

$y = \frac{90}{6}$

$y = 15$

Substitute 15 for y in $x = y + 2$

$x = 15 + 2$

$x = 17$

<em>Hence; the two odd numbers are 15 and 17</em>

Answer and question ok plss

ivolga24 [154]

Answer:

The answer is D(20)

Step-by-step explanation:

I don't know the exact algebraic explanation, however, this is how I did it.

$2^5+2^5=$ $2*2^5$

If you divide the second equation into seperate twos, you will get 2*2*2*2*2*2 = $2^6$

Therefore, $2^x=2^6$ meaning that x is equal to 6. Now The next bit is trial and error, 20-6=14. $3^{y} = 3^{14}$

Last thing to do is to add x+y=6+14. That is why the answer is 20.

If you wait a bit longer, someone will probably have a more algebraic explanation, however, you stated you only needed the answer so I hope this helped.

A random sample of n D 225 and xN D 21 was drawn from a normal population with a known

Rainbow [258]

Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm z\frac{\sigma}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

z is the critical value.

n is the sample size.

$\sigma$ is the standard deviation for the population.

In this problem, we have a 95% confidence level, hence $\alpha = 0.95$ , z is the value of Z that has a p-value of $\frac{1+0.95}{2} = 0.975$ , so the critical value is z = 1.96.

For this problem, the other parameters are:

$\overline{x} = 21, \sigma = 26.8, n = 225$

Hence the bounds of the interval are:

$\overline{x} - z\frac{\sigma}{\sqrt{n}} = 21 - 1.96\frac{26.8}{\sqrt{225}} = 17.5$

$\overline{x} + z\frac{\sigma}{\sqrt{n}} = 21 + 1.96\frac{26.8}{\sqrt{225}} = 24.5$

The interval is: (17.5, 24.5).
