Approximately 18% of the population of California is 70 years or older. In a random sample of 4, what is the provability for 3 o
Semmy [17]

Answer:

The correct response will be "0.01913".

Step-by-step explanation:

According to the question,

p - P(70 years or older)

= 0.18

n = 4

X = no. of individuals who are older than 70 years

Now,

∴ P(X=r)=n_C_r \ p^r(1-p)^{n-r}

∴ P(X=3)=4_C_3(0.18)^3(1-0.18)^{4-3}

                   =4\times (0.18)^3(0.82)^1

                   =0.01913

Please help find the perimeter
Usimov [2.4K]

Answer:

Perimeter of the given figure = 28 units

Step-by-step explanation:

Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH

Length of AB = 4.5 units

Length of BC = 2 units

Length of CD = 2 units

Length of DE = 4 units

Length of EF = 5.5 units

Length of FG = 1.5 units

Length of HG = 1 units

Length of AH = 7.5 units

Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5

                                          = 28 units

1.5^-2. how do i simplify that? the ^ means -2 is an exponant
hodyreva [135]
1.5 = 1 1/2 = 3/2
When there is a negative exponent, you find the reciprocal of the base, so therefore: 3/2 ^ -2 = 2/3 ^ 2
Then you square the numerator, then square the denominator: 2^2/3^2 = 4/9
