Answers

Answer:

(x, y) = (326, 457)

Step-by-step explanation:

Use the first equation to make an expression for y that can be substituted into the second.

y = 783 -x

10x +7(783 -x) = 6459

3x = 978 . . . . . . . . . . . . subtract 7(783) = 5481

x = 326 . . . . . . . . . . . . . divide by 3

y = 783 -326 = 457

The solution is (x, y) = (326, 457).

The spinner in a game based on chance has 25 equal sectors. The prize is worth $50, and the cost to play is $2.50. A player wins if the arrow lands on the sector he or she chose.

Which table shows the correct outcomes for a player who plays the game one time?

Answers

Answer:

________________ WIN _____ LOSE

Outcome(x) ______ $47.50 ____ - $2.50

PROBABILITY P(x) _____ __________

Step-by-step explanation:

Given that :

The cost of play = $2.50

The winning price = $50

Hence, if a player emerges victorious or wins; the net amount won is :

Winning price - cost of play

$50 - $2.50 = $47.50

If the player loses :

Then he wins $0

Net amount lost equals :

Amount won - cost of play

$0 - $2.50 = - $2.50

________________ WIN _____ LOSE

Outcome(x) ______ $47.50 ____ - $2.50

PROBABILITY P(x)

Write an equation in slope-intercept
form to represent the line
perpendicular to 6y = 9 - x with
y-intercept 2
O y = -6x + 2
O y = 2x + 9

Answers

Answer:

A, y= -6x + 2

Step-by-step explanation:

1. Put the equation into slope intercept form

6y = 9 - x

y= -1/6x + 9/6

The slope of equation 1 is -1/6

2. A perpendicular line is the inverse slope of our firsy equation. (-1/6)^-1 = -6.

3. The y intercept of a line in slope intercept form is the b value in the equation as written:

y=mx+b

Therefore, if m=-6 and b=2, our equation is

y= -6x + 2

Based on historical data, your manager believes that 30% of the company's orders come from first-time customers. A random sample of 64 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is greater than than 0.2?

Answers

Answer:

0.9594

Step-by-step explanation:

Given that:

Sample size (n) = 64

p = 30% = 0.3 ; 1 - p = 0.7

Probability that sample proportion is greater than 0.2

Mean (m) = n*p = 64 * 0.3 = 19.2

Standard deviation (s) = √n*p*(1-p) = √(19.2*0.7)= 3.67

0.2 of 64 = 12.8

Z > [(x - m) / s]

Z > (12.8 - 19.2) / 3.67

Z > (-6.4 /3.67)

Z > - 1.7438

= 0.9594

hi there! here's my answer for you...

Answer:

r = 6

Step-by-step explanation:

4r + 6r - 13 = 7r + 5

10r - 13 = 7r + 5

10r - 13 + 13 = 7r + 5 + 13

10r = 7r + 18

10r - 7r = 7r + 18 - 7r

3r = 18
