Graph the system below and write its solution. <br> 2X+Y=-6<br> Y= -1/3X-1

puteri [66]

2x + y = -6
y = ⁻¹/₃x - 1

2x + (⁻¹/₃x - 1) = -6
2x - ¹/₃x - 1 = -6
1²/₃x - 1 = -6
+ 1 + 1
1²/₃x = -5
1²/₃ 1²/₃
x = -3

y = ⁻¹/₃x - 1
y = ⁻¹/₃(-3) - 1
y = 1 - 1
y = 0
(x, y)= (-3, 0)

A film distribution manager calculates that 9%9% of the films released are flops. If the manager is right, what is the probabili

alexdok [17]

Answer:

The probability that the proportion of flops in a sample of 442 released films would differ from the population proportion by greater than 4% is:

= 0.094

= 9.4%

Step-by-step Explanation:

Estimated probability that the films released are flops = 9%

Sample of released films = 442

Estimated number of flops = 39.78 (442 * 9%)

If the population proportion of flops will be greater by 4%,

Therefore, the number of flops will increase to 41.37 (39.78 * 1.04)

This gives a new proportion of flops as 0.0936 (41.37/442)
