Health club a charges 100.00 membership fee plus 25.00 per plus 25.00 per month

Snowcat [4.5K]

Answer:

Month 5 the cost will be the same

Step-by-step explanation:

Make to equations from the given information

Let y be the cost, and let x be the number of months

Club A: y = 25x + 100

Club B: y = 20x + 200

It wants to know when the cost will be the same, so set the 2 equations equal to each other and solve..

25x + 100 = 20x + 200

5x = 100 (subtract 20x and 100 from both sides)

x = 20 (divide both sides by 5)

So after 5 months the cost will be equal,

HELPPPPPPPPPP!!!!!!! Calculate the correlation coefficient for the following data, showing all work. What does it tell you about

stiks02 [169]

Answer:

I will show the way.

Step-by-step explanation:

r is the correlation coefficient

$r=\frac{SSxy}{\sqrt{(SSxx)(SSyy)}}$

To find SSxy

SSxy= ∑ $xy$ - ∑ $\frac{(x)(y)}{n}$

To find SSxx

SSxy= ∑ $x^{2}$ - $($ ∑x $)^{2}$ /n

To find SSyy

SSxy= ∑ $y^{2}$ - $($ ∑y $)^{2}$ /n

if your r is near +1, it shows strong positive correlation. Y is proportional to X.

And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.

7. Triangles CDE and RST are similar triangles. What is

andreyandreev [35.5K]

Answer:

CD = 25 ft

Step-by-step explanation:

$\triangle CDE \sim \triangle RST$

$\therefore \frac{CD}{20}=\frac{40}{32}$

(Corresponding sides of similar triangles are in proportion)

$\therefore \frac{CD}{20}=\frac{5}{4}$

$\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}}$

$\therefore CD = 5\times 5$

$\therefore CD = 25\: ft$
