Consider the probability that more than 70 out of 119 CDs will be defective. Assume the probability that a given CD will be defe
goldfiish [28.3K]

Answer: No, the normal curve cannot be used.

Step-by-step explanation:

The theorem of the Normal approximation states that if X is B(n,p) then for large n X is N(np, np(1-p)).

The accuracy of this approximation is good

i. for n > [10/p(1-p)]

ii. p is close to 1/2

Hence given p= 4% = 0.04,

q = 1 - 0.04 = 0.96

Let N = [10/p(1-p)]

We find N = 10/p(1-p) = 10/(0.04× 0.96)

N ~= 260

Since n < 260 and p < 0.5

The approximation is not a good one

during the first round of game show, jackson scored 300 points. After the second round,after the second round, his total score w
mrs_skeptik [129]

Answer:

-600

Step-by-step explanation:

Jackson's initial score was 300, then his later score became -300, so you know that he had to lose points.

-300=300+x

** x represents the point change

Then just solve the equation by getting x by itself. You do this by subtracting 300 from both sides:

-300=300+x

-300 -300 = -300-300+x

-600 = x

snow_lady [41]
Equation for company a: y=20x+8
Equation for company b: y=24x+4
Company A would be cheaper for 5 loads of laundry, because it is $108 dollars opposed to $124 which is what company b would charge for 5 loads.
$32 dollars is saved by using the services of company A instead of company B to clean 9 loads of laundry.
