The probability that an even number is rolled 15 or fewer times when the die is rolled 25 times total can be calculated using the binomial probability formula. In this case, the probability of success is rolling an even number (0.65) and the number of trials is 25.

Using the binomial probability formula, we can calculate the probability of getting 15 or fewer even numbers when the die is rolled 25 times as follows:

P (X <= 15) = P (X = 0) + P (X = 1) + P (X = 2) + ... + P (X = 15)

Where X is the number of even numbers rolled and P(X) is the probability of getting X even numbers.

Using the binomial probability formula:

P(X) = (25 choose X) * (0.65)^X * (0.35)^(25-X)

Plugging in the values, we get:

P(X <= 15) = (25 choose 0) * (0.65)^0 * (0.35)^25 + (25 choose 1) * (0.65)^1 * (0.35)^24 + (25 choose 2) * (0.65)^2 * (0.35)^23 + ... + (25 choose 15) * (0.65)^15 * (0.35)^10

After calculating all the values, we get that the probability of rolling an even number 15 or fewer times when the die is rolled 25 times is about 0.28.

Therefore, the closest answer choice to the probability that an even number is rolled 15 or fewer times when the die is rolled 25 times is 0.25.

Answer:

h = 6 m

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂)

where h is the perpendicular height between the bases b₁ and b₂

given A = 51 , b₁ = 10 and b₂ = 7 , then

[tex]\frac{1}{2}[/tex] h (10 + 7) = 51 ( multiply both sides by 2 to clear the fraction )

17h = 102 ( divide both sides by 17 )

h = 6 m

Find the height of the trapezoid.

if the area of the trapezoid is [tex]51m^{2}[/tex] and parallel sides are [tex]7m[/tex] and [tex]10m[/tex].

To find the height of the trapezoid, substitute the area and parallel sides into the formula for the area of the trapezoid.

Trapezoid area formula is

[tex]L=\frac{1}{2}(number of parallel sides)(height)\\ L=\frac{1}{2} (a+b)(t)[/tex]

The next step is substitute the area and parallel sides into the formula for the area of the trapezoid.

[tex]51=\frac{1}{2}(7+10)(t)[/tex]

Complete the arithmetic operation

[tex]51=\frac{1}{2}(17)(t)\\ 51=\frac{17}{2}(t)[/tex]

Multiply each side by [tex]\frac{2}{17}[/tex]

[tex]51(\frac{2}{17}) =\frac{17}{2}(\frac{2}{17})(t)\\ 6=t[/tex]

Ridge regression is a type of linear regression used to reduce the effects of multi-collinearity. It is used with 1000 labeled examples to minimize the sum of the squared errors of the model.

Ridge regression is a type of linear regression used to reduce the effects of multi-collinearity. It adds a penalty term to the cost function that penalizes large coefficients, thus reducing their magnitude. The penalty term is a regularization term that is added to the cost function to minimize overfitting. To use ridge regression, one must select a value for the regularization parameter. This parameter determines how much the model weights the penalty term, and is usually determined through cross-validation. With 1000 labeled examples, ridge regression can be used to minimize the sum of the squared errors of the model. The model is then trained on the data, and predictions can be made. Ridge regression is a powerful tool for reducing the effects of multi-collinearity, and can be used to accurately model relationships between variables.

To find the value of f(g(-4)), we need to first substitute -4 into the definition of g(x) and then substitute the result into the definition of f(x).

First we substitute -4 into g(x):

g(-4) = 2(-4)^2 + 4(-4) - 8

g(-4) = 2(16) + (-16) - 8

g(-4) = 32 - 16 - 8

g(-4) = 8

Now we substitute 8 into f(x):

f(g(-4)) = f(8) = 2(8) - 4 = 16 - 4 = 12

So the value of f(g(-4)) is 12.

Answer:

28

Step-by-step explanation:

The expression: f(g(-4)) just means calculate the value of g at x = -4 and then calculate what f is equal to at that value g is equal to, so we have to first calculate g(-4) which we can do by substituting in -4 as x.

g(-4) = 2(-4)^2 + 4(-4) - 8

g(-4) = 2(16) - 8 - 8

g(-4) = 32 - 16

g(-4) = 16

Now from here we can substitute 16 as g(-4) in the expression f(g(-4)) which means we want to evaluate g(16) which we can do by substituting in 16 as x.

f(16) = 2(16) - 4

f(16) = 32 - 4

f(16) = 28

So that means f(g(-4)) = 28

The decay rate of the cell phones is 0.3333, and the median lifetime of the phones is 2.0794 years.

The decay rate of the cell phones is 0.3333, and the median lifetime of the phones is 2.0794 years.

1)a. 0.3333

2)c. 2.0794

1)The decay rate is found by dividing 1 by the average lifetime (in this case, 3 years). Therefore, the decay rate is 1/3 = 0.3333.

2)The median lifetime of these phones is found by taking the natural logarithm of 0.5 (which is the probability of the phone failing within 2 years) and dividing it by the decay rate (0.3333). Therefore, the median lifetime is ln(0.5)/0.3333 = 2.0794.

b) 6x² - x³ ≤ -x² + 2x + 3

To solve for x in the given inequalities:

a) 6x² - x³ = -x² + 2x + 3

Start by isolating x³ on one side of the equation:

x³ = 6x² + (-x² + 2x + 3)

x³ = 6x² + 2x + 3

x³ = (x²)(6 + 2/x) + 3

This equation holds true for all x values except x=0, because it would result in division by zero.

b) 6x² - x³ ≤ -x² + 2x + 3

Start by isolating x³ on one side of the inequality:

We need to verify that the opposite sides of the quadrilateral are equal in length and that the opposite angles are equal. We can use the formula for the area of a parallelogram: A = b*h, where b is the length of the base and h is the height of the parallelogram. We can also use the formula for the sum of the angles of a quadrilateral: A1 + A2 + A3 + A4 = 360 degrees.
