What is the probability that a fair die never comes up an even number when it is rolled six times? (note: enter the value of pro
seropon [69]
Let us compute first the probability of ending up an odd number when rolling a dice. A dice has faces with numbers 1 up to 6. The odd numbers within that is 3 (1, 3 and 5). Therefore, each dice has a probability of 3/6 or 1/2. Then, you use the repeated trials formula:

Probability = n!/r!(n-r)! * p^r * q^(n-r), where n is the number of tries (n=6), r is the number tries where you get an even number (r=0), p is the probability of having an even face and q is the probability of having an odd face.

Probability = 6!/0!(6!) * (1/2)^0 * (1/2)^6
Probability = 1/64

Therefore, the probability is 1/64 or 1.56%.

The vertex of the parabola is at (0,0), and the focus is at (0,-7). 

The focus is given by the following values:

(h, k + p)

h and k represent the x and y values of the vertex. We want to solve for p.

Set the y value for the focus equal to -7:

k + p = -7

We know that k = 0, so we can simplify to get p by itself:

p = -7

Standard form of a vertical parabola is given by the following formula:

(y - k)^2 = 4p(x - h)

Plug in all of your known values into the formula:

h = 0, k = 0, p = -7

(y - 0)^2 = 4(-7)(x - 0)
y^2 = -28x

The answer is "y^2 = -28x".

A grocery store has a 13%-off sale on al breads. You decide to purchase 6 loaves of bread. Let b be the original price of a loaf
blagie [28]

The term 6b represents the original price of loaves of bread and 0.78b represents the amount of discount on 6 loaves of bread.

Step-by-step explanation:

Given,

Sale = 13% off

Number of bread purchased = 6

Original price of loaf of bread = b

The given expression is;

6(b-0.13b)

Expanding the expression;

6b-0.78b

5.22b

Here;

The term 6b represents the original price of loaves of bread and 0.78b represents the amount of discount on 6 loaves of bread.
