We need to roll a die at least 3 times and a coin should be tossed at least 2 times.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given this, Becca repeatedly tosses a fair coin until she gets a head.

The probability of getting a head P(H) is = 1/2.

The probability of getting a number 3 or higher is,

P(3) + P(4) + P(5) + P(6).

= 1/6 + 1/6 + 1/6 + 1/6.

= 4/6.

= 2/3.

So, to get a number 3 or higher we need at least 3 rolls, and to get a head we need at least 2 tosses.

The probability that the servers will run for at least 56 days, given that they have been running for 16 days, is approximately 0.063.

Since the time between failures of the video streaming service follows an exponential distribution with a mean of 20 days, the parameter λ of the distribution can be calculated as:

λ = 1 / mean = 1 / 20 = 0.05

Let X be the time between failures of the video streaming service. Then X follows an exponential distribution with parameter λ = 0.05, and the probability density function of X is given by:

f(x) = λ e^(-λx)

We want to find the probability that the servers will run for at least 56 days, given that they have been running for 16 days. That is:

P(X > 56 | X > 16)

Using the conditional probability formula, we have:

P(X > 56 | X > 16) = P(X > 56 and X > 16) / P(X > 16)

Since X is a continuous random variable, we can use the cumulative distribution function (CDF) to calculate the probabilities:

P(X > 56 and X > 16) = P(X > 56)

= ∫56∞ λ e^(-λx) dx

= e^(-λx) |56∞

= e^(-0.05*56)

≈ 0.0284

P(X > 16) = ∫16∞ λ e^(-λx) dx

= e^(-λx) |16∞

= e^(-0.05×16)

≈ 0.4493

Therefore, P(X > 56 | X > 16) = P(X > 56 and X > 16) / P(X > 16)

= 0.0284 / 0.4493

≈ 0.0632

Answer:

x = 4, y = 5.

Step-by-step explanation:

4x-2=3y-1

y+3=3x-4

Rearranging:

4x - 3y =  1       (A)

-3x + y = -7      (B)

Multiply  B by 3:

Answer:

\(12.50 \space\ h = 2500.75\)

Step-by-step explanation:

We know from the question that the student earned $12.50 per hour.

Using this information, we can say that if the student worked for h hours, they would make a total of 12.50 × h dollars.

We also know that the total money they earned is $2500.75.

∴ Therefore, we can set up the following equation:

\(\boxed {12.50 \times h = 2500.75}\)

From here, if we want to, we can find the number of hours worked by simply making h the subject of the equation and evaluating:

h = \(\frac{2500.75}{12.50}\)

  = 200.6 hours

Answer: 12.50h = 2500.75

For an interest rate of 8%, we divide 72 by 8: 72 / 8 = 9. Thus, it would take around 9 years for the savings to double at an interest rate of 8%.

The "Rule of 72" is a quick estimation method to determine the time it takes for an investment or savings to double in value. By dividing 72 by the interest rate, you can obtain an approximation of the doubling time. For an interest rate of 3%, it would take approximately 24 years for the savings to double. For an interest rate of 8%, it would take around 9 years for the savings to double.

To calculate the doubling time using the Rule of 72, divide 72 by the interest rate. This provides an approximation of the number of years it takes for an investment or savings to double in value.

For an interest rate of 3%, we divide 72 by 3: 72 / 3 = 24. Therefore, it would take approximately 24 years for the savings to double.

For an interest rate of 8%, we divide 72 by 8: 72 / 8 = 9. Thus, it would take around 9 years for the savings to double at an interest rate of 8%.

Answer:

0.00456

Step-by-step explanation:

Given: Percentage of free throws = 74%

Required:  What is the probability of Glen Davis making none of his next 4 free throw attempts?

Since, there is a free throw 74% of the time, thus, the time he misses = 26% of the time.

To miss four in a row, it is requires to miss the first throw, the second throw, the third throw and also the fourth throw.

Thus, the probabilities of Gien missing will be multiplied.

By using the probability formula -

P ( MMMM) = 26/100 × 26/100 × 26/100 × 26/100

                   = 456976/ 100000000

                   = 0.00456

Therefore, the probability that he will have next 4 free attempts is 0.00456.

D. (3.5, 2.25)

Step-by-step explanation:

A solution to the system is where the two equations intersect.

looking at the graph, we see that the intersection point is between x= 3 and 4, and Y = 2 and 3.

Answer:

(3.5, 2.25)

Step-by-step explanation:

To find the coordinate of the solution to the system of linear equations −3x + 2y = −6 and y = -1/2x + 4, we need to solve the system. One method to do this is substitution. We can solve one of the equations for y, then substitute the expression for y into the other equation. This will give us an equation in terms of x, which we can then solve for x. Then, we can substitute the value of x back into one of the equations to find the corresponding value of y.

Using substitution, we can solve the system as follows:

y = -1/2x + 4

-3x + 2y = -6

Substitute y = -1/2x + 4 into -3x + 2y = -6:

-3x + 2(-1/2x + 4) = -6

-3x + (-x + 8) = -6

-4x + 8 = -6

-4x = -14

x = 3.5

Substitute x = 3.5 into y = -1/2x + 4:

y = -1/2(3.5) + 4

y = 2.25

Therefore, the solution to the system is approximately (3.5, 2.25).

The magnitude or length of AB, represented as ||AB||, is calculated using the distance formula resulting in √101.

To sketch AB, plot the initial point A(8, -4) and the terminal point B(-2, -3) on a coordinate plane. Then, draw a line segment connecting these two points. The line segment AB represents the vector AB.

To write AB in component form, subtract the x-coordinates of B from the x-coordinate of A and the y-coordinates of B from the y-coordinate of A. This gives us the vector (-2 - 8, -3 - (-4)), which simplifies to (-10, 1). Therefore, AB can be represented as the vector (-10, 1).

To find the magnitude or length of AB, we can use the distance formula. The distance formula calculates the distance between two points in a coordinate plane. Applying the distance formula to AB, we have √((-2 - 8)² + (-3 - (-4))²). Simplifying the equation inside the square root, we get √(100 + 1), which further simplifies to √101. Thus, the magnitude or length of AB, denoted as ||AB||, is √101.
