Answer:

P(X>4)= 0.624

Step-by-step explanation:

Given that

n = 10

p= 0.5 ,q= 1 - p = 0.5

Two fifth of 10 = 2/5 x 10 =4

It means that we have to find probability P(X>4).

P(X>4)= 1 -P(X=0)-P(X=1)-P(X=2)-P(X=3)-P(X=4)

We know that

$P(X=x)=(_{x}^{n})\ p^xq^{n-x}$

$P(X=0)=(_{0}^{10})\ 0.5^0\ 0.5^{10}=0.0009$

$P(X=1)=(_{1}^{10})\ 0.5^1\ 0.5^{9}=0.0097$

$P(X=2)=(_{2}^{10})\ 0.5^2\ 0.5^{8}=0.043$

$P(X=3)=(_{3}^{10})\ 0.5^3\ 0.5^{7}=0.117$

$P(X=4)=(_{4}^{10})\ 0.5^3\ 0.5^{7}=0.205$

P(X>4)= 1 -P(X=0)-P(X=1)-P(X=2)-P(X=3)-P(X=4)

P(X>4)= 1 -0.0009 - 0.0097 - 0.043 - 0.117-0.205

P(X>4)= 0.624

1: a 24 ounce box of cornflakes cost $4.59?

mestny [16]

The unit rate for the 1st one is: $0.19 / ounce

The unit rate for the 2nd one is: $0.16 / ounce

The 36 ounce box would be the better buy because it is less per ounce than the 24 ounce box

Mrs. Salas drives 115 miles per week to give 9 voice lessons. She deducts the cost of eight gallons of gasoline at $2 per gallon

ladessa [460]

the answer is $299. If you write an equation, it would be x=35(9)-16. $35 each for 9 lessons. And 2*8= 16.

x=35(9)-16

x=315-16

x=299
