Answer:

r = - $\frac{6a}{1-5m^2}$

Step-by-step explanation:

Rewrite the equation as $\sqrt{x} 6a+r/5r$ = m

Remove the radical on the left side of the equation by squaring both sides of the equation.

( $\sqrt{\frac{6a+r}{5r} )^{2}$ = m^2

Then, you simplify each of the equation.

Rewrite: ( $\sqrt{\frac{6a+r}{5r} )^{2}$ as $\frac{6a+r}{5r} = m^{2}$

Remove any parentheses if needed.

Solve for r.

Multiply each term by r and simplify."

Multiply both sides of the equation by 5.

6a+r= m^2r⋅(5)

Remove parentheses.

Move 5 to the left of (m ^2) r

6a+r=5m^2)r

Subtract 5m^2)r from both sides of the equation.

6a+r-5m^2)r=0

Subtract 6a from both sides of the equation.

r-5m^2)r=-6a

Factor r out of r-5m^2)r

r(1-5m^2)=-6a

Divide each term by 1-5m^2 and simplify.

r = - $\frac{6a}{1-5m^2}$

There you go, hope this helps!

The following are the last 7 days adjusted closing stock prices (in $) for Citigroup: 22, 25, 20, 15, 40, 55, 28 A) Compute the

son4ous [18]

Answer:

(A) The 25th percentile is 20.

(B) The mean of the data set is 20 and the median of the data set is 25. The data set is left-skewed.

Step-by-step explanation:

The data set arranged in ascending order is:

S = {15, 20, 22, 25, 28, 40, 55}

(A)

Compute the 25th percentile as follows:

$25^{th} \text{Percentile}=[\frac{n+1}{4}]^{th}obs.\\\\=[\frac{7+1}{4}]^{th}obs.\\\\=2^{nd}obs.\\\\=20$

Thus, the 25th percentile is 20. This value implies that exactly 25% of the observations are less than 20.

(B)

Compute the sample mean as follows:

$\text{Mean}=\frac{22+25+20+15+40+55+28}{7}=\frac{205}{7}=29.29$

Compute the median as follows:

For a set with odd number of observations, the median value if the middle value.

The middle value is 25.

Thus, the mean of the data set is 20 and the median of the data set is 25.

The Mean < Median.

This implies that the data set is left-skewed.

What is 1920000000 Minutes in Hours?

Vlada [557]

Answer:

<h2>1,920,000,000 Minutes = 32,000,000 Hours</h2>

Step-by-step explanation:

$1h=60min\to1min=\dfrac{1}{60}h\\\\\text{therefore}\\\\1,920,000,000min=\dfrac{1,920,000,000}{60}\ h=32,000,000h$

25 POINTS AND BRAINLIEST!

Andrew [12]

The area of a hexagon is attached as a picture, where a is the length of a side of a regular hexagon. Since the radius equals the side length, the hexagon is regular.

By plugging into the equation, you get an area of 210.4 units squared

To help pay for the next school event, Terry and Tony want to make a

Sloan [31]

a) Equation: $Nx=475$

b)

1st case: 119 tickets

2nd case: 106 tickets

3rd case: 95 tickets

Step-by-step explanation:

a)

Terry and Tony want to make a profit of

P = $475

in total from the ticket sale.

Here we call $x$ the price per ticket.

Then we also call $N$ the number of tickets sold: therefore, this total profit made by Terry and Tony from the ticket sale is the product between the tickets sold, N, and the price per ticket, x:
