Answer:

60.63%

Step-by-step explanation:

Prob. of students who regularly attend = 45%

Prob. of students who don't attend = 55%

Upper Class Students who attend = 64 % of 45 %

= 0.64 × 0.45 × 100 = 28.8% = 0.288

Upper Class Students who don't attend = 34 % of 55% = 0.34 × 0.55 × 100 = 18.7% = 0.187

Total for Upper Class Students = 28.8% + 18.7% = 47.5% = 0.475

Probability that an Upper Class Student randomly selected will be attending = ( 0.288 / 0.475 ) × 100 = 0.6063 × 100 = 60.63%

Kobotan [32]

Answer:

The answer to your question is See the attachment

Step-by-step explanation:

Equation

(x - 8)² + (y + 5)² = 4

Process

1.- Write the standard equation of the circle

(x - h)² + (y - k)² = r²

2.- Find the center

The center are the letters h and k

h = 8 k = -5

3.- Find the radius

r = 2

4.- Graph the circle ( i will use geogebra)

forsale [732]

Answer:

21.43 miles

Step-by-step explanation:

Let

x ---> the number of miles

y ---> the total cost of rent a car per day

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

sunshine rental company

The slope is equal to

$m=\$0.50\ per\ mile$

The y-intercept is equal to

$b=\$17$

substitute

$y=0.50x+17$ ----> equation A

rent me company

The slope is equal to

$m=\$0.36\ per\ mile$

The y-intercept is equal to

$b=\$20$

substitute

$y=0.36x+20$ ----> equation B

equate equation A and equation B

$0.50x+17=0.36x+20$

solve for x

$0.50x-0.36x=20-17\\0.14x=3\\x=21.43\ miles$

A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled.

So the answer would be C

But lets see the proof:
The first x and y ratio is 2:6 which equals 1:3
The second one is 4:12 which equals 1:3
The third one is 6: 18 which equals 1:3
The fourth one is 8: 24 which equals 1:3

Which means all 4 of the ratios are the same. So therefore the answer is C
