If 20% of the people who shop at a local grocery store buy apples, what is the probability that it will take no more than 5 cust

Leokris [45]

Answer:

C) Using a random digits table select one digit numbers where 0-1 is a customer who buys apples and 2-9 is a customer who does not. Keep selecting one digit numbers until you get a 0 or 1. Record the number of digits selected.

Step-by-step explanation:

There are 10 digits from 0 to 10

0-1 are 2 out of 10

2/10 × 100 = 20%

Therefore 20% chance of buying apples

The difference between five and twice a number, x, is one.

tia_tia [17]

" the difference " means subtract

the difference between 5 and twice a number x is 1

5 - 2x = 1 <== ur equation
-2x = 1 - 5
-2x = - 4
x = -4/-2
x = 2 <== ur solution

Solve by completing squares method...1/x +1/x -1 =4...please answer ASAP

maxonik [38]

Answer:

1.31, 0.19 to nearest hundredth.

Step-by-step explanation:

1/x + 1/(x - 1) = 4

Multiply through by x(x - 1):-

x - 1 + x = 4x(x - 1)

4x^2 - 4x = 2x - 1

4x^2 - 6x = -1

4(x^2 - 3.2 x) = -1

Completing the square:-

4 [ ( x - 3/4)^2 - 9/16] = -1

4(x - 3/4)^2 - 9/4 = -1

4(x - 3/4)^2 = 5/4

(x - 3/4)^2 = 5/16

x - 3/4 = +/- √5 / 4

x = √5 / 4 + 3/4 , -√5 / 4 + 3/4

= 1.31, 0.19 to nearest hundredth.

Jessica and Martha each have a bag of cookies with unequal quantities. They have 30 cookies total between the two of them. Each

Basile [38]

Answer:

Part 1) The inequality that describes the relationship between the number of cookies each one of them has is $x^{2} -30x+224\geq 0$

Part 2) Jessica has at least 2 cookies more than Martha

Step-by-step explanation:

Part 1) Find the inequality that describes the relationship between the number of cookies each one of them has

Let

x----> the number of cookies when Jessica started

30-x ----> the number of cookies when Martha started

we know that

Each of them ate 6 cookies from their bag

The cookies left in each bag are

(x-6) ----> Jessica

and (30-x-6)=(24-x) ---> Martha

The product is equal to (x-6)(24-x)

The product of the number of cookies left in each bag is not more than 80.

$(x-6)(24-x)\leq 80\\ \\24x-x^{2}-144+6x\leq 80\\ \\-x^{2} +30x-144-80\leq 0\\ \\-x^{2} +30x-224\leq 0$

Multiply by -1 both sides

$x^{2} -30x+224\geq 0$

Part 2) Solve the quadratic equation

$x^{2} -30x+224\geq 0$

Solve by graphing

The solution is x=16 cookies

(30-x)=30-16=14 cookies

therefore

The number of cookies when Jessica started was 16 cookies

The number of cookies when Martha started was 14 cookies

The number of cookies left in each bag is equal to

Jessica

16-6=10 cookies

Martha

14-6=8 cookies

Jessica has at least 2 cookies more than Martha
