According to a report from the Center for Studying Health System Change, 20% of Americans delay or go without medical care becau

Svet_ta [14]

Answer:

The probability no one delays or goes without medical care is 0.168;

The probability only one person delays or goes without medical care is 0.336.

Step-by-step explanation:

This problem can be modeled with a binomial random variable, with sample size n=8 and probability of success p=0.2.

The probability that exactly k Americans delay or go without medical care because of concerns about cost within the sample of eight individuals can be calculated as:

$P(x=k) = \dbinom{n}{k} p^{k}(1-p)^{n-k}\\\\\\P(x=k) = \dbinom{8}{k} 0.2^{k} 0.8^{8-k}\\\\\\$

The probability no one delays or goes without medical care (x=0) is:

$P(x=0) = \dbinom{8}{0} p^{0}(1-p)^{8}=1*1*0.168=0.168\\\\\\$

The probability only one person delays or goes without medical care (x=1) is

$P(x=1) = \dbinom{8}{1} p^{1}(1-p)^{7}=8*0.2*0.21=0.336\\\\\\$

A label that wraps around a box of golf balls covers 75% of its lateral surface area. What is the value of x? The height is 2 th

GalinKa [24]

To find the area of the rectangular prism, use the formula:

A = width x height x length

A = 2 x 2 x 3

A = 12

Now multiply A with 0.75

12 x 0.75 = 9

x = 9 in³

Solve the system by substitution. y = 8x y = 4x + 8

Taya2010 [7]

Answer:

y = 16

x = 2

Step-by-step explanation:

y = 8x

y = 4x + 8

then, by substitution:

8x = 4x + 8

8x - 4x = 8

4x = 8

x = 8/4

x = 2

y = 8x

y = 8*2

y = 16

Check:

y = 4x + 8

y = 4*2 + 8

16 = 8 + 8
