To win the game, eitan has to roll a sum of 11 or more using two six-sided number cubes. asher has a better probability of winning than eitan has. which could be the outcome that asher needs to win the game? check all that apply.

Answer: (My view) 6.

Step-by-step explanation: Letting "n" be the number of pictures taken. The probability of no one look at the camera for n photos is of (3/4)^n.

Hence, the probability of at least one photo be the picture craven is of:

(1 - (3/4)^n), and since the likelihood of that being equal to 4/5, it's feasible to assume that (1 - (3/4)^n) = 4/5, solving for that would give:

(3/4)^n = 1/5. Notice that the proposal can also be interpreted as "The number of pictures needed such that the probability of a picture NOT including one with everyone looking at the camera is at most 1/5",

Therefore, (3/4)^n < 1/5;

To solve for that:

n = 1:

3/4 > 1/5,

n = 2:

9/16 > 1/5

n = 3

27/64 > 1/5

n = 4

81/256 > 1/5

n = 5

243/1024 > 1/5

But finally:

n = 6

729/4096 < 1/5

For at least 6 pictures she must take to have at least a 4/5 chance of having a picture in which everyone is looking at the camera.

Let p define the probability of success in a Bernoulli trial, and P define the probability Sara wants to reach "at least" and n be defined as the number of trials. Then,

= 1 - (1 - p)ⁿ ≥ P

= (1 - p)ⁿ ≤ 1 - P

= n ≥ ln(1-P)/ln(1-p)

= n ≥ ln (0.2) / ln (0.75)

=5.6

Hence for at least n=6 photos, there is at least a chance of 4/5 that everyone is looking at the camera.

The equation that has 2 as its root is 2x² - 7x + 6 = 0 (option c)

Suppose we are given a quadratic function f(x) = ax² + bx + c, then x = q is a root if f(q) = 0.

Let's check for the given functions:

a.  x² - 4x + 5 = 0

f(2) =  2² - 4(2) + 5

f(2) = 4 - 8 + 5 = 1

Since f(2) ≠ 0, hence 2 is not its root.

b. x² + 3x - 12 = 0

f(2) = 2² + 3(2) - 12

f(2) = 4 + 6 - 12 = -2

Since f(2) ≠ 0, hence 2 is not its root.

c. 2x² - 7x + 6 = 0

f(2) = 2(2)² - 7(2)+ 6

f(2) = 2(4) - 14 + 6 = 0

Hence, x = 2 is its root.

d. 3x² - 6x - 2 = 0

f(2) = 3(2)² - 6(2) - 2

f(2) = 12 - 12 - 2 = -2

Since f(2) ≠ 0, hence 2 is not its root.

Hence, the correct option is   2x² - 7x + 6 = 0 (option c)

The linearization of the function at a is L(x) = 1/2 + √3/2(x - π/6).

Linearization is a method of taking the gradient of a nonlinear function with respect to all variables. It is used to approximate the output of a function based on the value and slope of the function, at a given point.

The Linearization of function f(x,y) at (a,b) is L(x,y) = f(a,b) + (x−a)fx(a,b) +(y−b)fy(a,b)

Now we take a look at the given function, and the value of point a:

f(x) = sin (x)

a = π/6

Then we differentiate the function, with respect to x:

f(x) = sin (x)

f’(x) = cos (x)

We input the value of a = π/6 into the function:

y = f(π/6)

  = sin (π/6)

  = 1/2

f’(π/6) = cos (π/6)

          = √3/2

Now we input the value of f(a) and f'(a) into the linearization formulas:

L(x) = f(a) + f'(a)(x - a)

      = 1/2 + √3/2 (x - π/6)

Thus the linearization of the function at a is L(x) = 1/2 + √3/2(x - π/6).

The solution of the inequality is x < -15/2x.

What is the linear equation?

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of a linear equation is y=mx + b.

We can start solving the inequality by first isolating x on one side of the inequality.

x(2x-1)>15

Divide both sides by x(2x-1)

1>15/(x(2x-1))

To get rid of the fraction, we can invert the inequality and multiply both sides by x(2x-1)

x(2x-1)<15

Now we can simplify the inequality by factoring the left side:

x(2x-1)<15

2x-1 < 15/x

2x < 15/x + 1

2x < (15 + x) / x

Now we can multiply both sides by x

2x*x < 15 + x

2x^2 < 15 + x

Now we can subtract x from both sides

2x^2 - x < 15

Now we can factor the left side

(x-5)(2x+3) < 0

Now we can find the solution of the inequality by finding the values of x that make the inequality true

x = 5, 2x +3 < 0

x < -15/2x

Hence, the solution of the inequality is x < -15/2x.

Answer:

The difference between constant and variable is that, while the first, as we have already said, remains fixed within a formula, the variable can assume different values.

Step-by-step explanation:

A constant term in an expression is a term that has a fixed value and does not change, while a variable term is a term that can take on different values. For example, in the expression 5x + 2, the 2 is a constant term because it is always 2, while x is a variable term that can take on different values.

In a real-world situation, a constant term represents a quantity that does not change. For example, if we were to write an expression to represent the cost of a product, the constant term would be the fixed cost of the product that does not change. On the other hand, a variable term represents a quantity that is subject to change. For example, in the same scenario, the variable term would represent the quantity of the product being bought, which can change.

In summary, a constant term represents a fixed value that does not change, while a variable term represents a value that is subject to change in a real-world situation.

II) Number of customers who would expect to buy 44 L of petrol is 2.28

i)The amount of petrol sold by the petrol station on a particular day can be estimated using the following equation:

Total petrol sold = Mean amount of petrol per customer x Number of customers

= 36 L x 600 customers

= 21,600 L

ii) To find the number of customers who would expect to buy 44 L of petrol, we need to find the probability of a customer buying that amount. We can use the standard normal table and the z-score formula (z = (x - mean) / std dev) to calculate the probability of a customer buying 44 liters of petrol.

z = (44 - 36) / 7 = 2.57

Using the standard normal table, we can find that the probability of a customer buying 44 liters of petrol is about 0.0038 or 0.38%.

Therefore, we can estimate that about 2.28 customers would expect to buy 44 liters of petrol on that day by multiplying the probability of buying 44 liters of petrol by the total number of customers.

A correlation is a measure of the relationship between two variables that is expressed as a numerical value between -1 and 1. To calculate a correlation, start by collecting data on the two variables. Then, calculate the covariance, which is the sum of the product of the differences between the two variables, divided by the number of data points. Finally, calculate the correlation by dividing the covariance by the product of the standard deviations of the two variables. The correlation can range from -1, which signifies a perfect negative correlation, to 1, which signifies a perfect positive correlation.

a. To find dy/dx when y = 2xlog e (2x), we can use the chain rule. First, we rewrite the function as y = 2x(ln(2x) + 1) where ln is the natural logarithm. Then, we can take the derivative of y with respect to x:

dy/dx = 2(ln(2x) + 1) + 2x(1/2x) = 2ln(2x) + 2 + 2/x

b. To find f′(0) when f(x) = e^x^2/e^x+1, we can take the derivative of the function with respect to x:

f′(x) = (2xe^x^2(e^x+1) - e^x^2(e^x+1)) / (e^x+1)^2

Setting x = 0, we get:

f′(0) = 2e^0(e^0 + 1) - e^0(e^0 + 1) / (e^0 + 1)^2 = 1 / (e^0 + 1)^2 = 1 / 2^2 = 1/4
