The probability that the cycle time exceeds 60 minutes given that it exceeds 55 minutes is 2/1 or simply 1, which means it is certain that the cycle time exceeds 60 minutes if it exceeds 55 minutes.

Given that the cycle time for trucks hauling concrete to a highway construction site is uniformly distributed over the interval 50 to 70 minutes, we know that the probability density function is:

f(x) = 1 / (70 - 50) = 1/20, for 50 <= x <= 70

To find the probability that the cycle time exceeds 60 minutes given that it exceeds 55 minutes, we need to use conditional probability:

P(X > 60 | X > 55) = P(X > 60 and X > 55) / P(X > 55)

We can simplify this by noticing that if X is greater than 55, then it must be between 55 and 70, and therefore:

P(X > 55) = P(55 <= X <= 70) = (70 - 55) / (70 - 50) = 1/4

Similarly, we can rewrite the numerator as:

P(X > 60 and X > 55) = P(X > 60)

since if X is greater than 60, it is also greater than 55.

Now, to find P(X > 60), we integrate the density function from 60 to 70:

P(X > 60) = ∫60^70 (1/20) dx = (1/20) × (70 - 60) = 1/2

Putting it all together:

P(X > 60 | X > 55) = P(X > 60 and X > 55) / P(X > 55)

= P(X > 60) / P(X > 55)

= (1/2) / (1/4)

= 2

Answer:

e) 5, 12, and 13

Step-by-step explanation:

To find if the given triangle is right triangle, use Pythagorean theorem.

If the sum of the squares of the two smaller sides equals the square of the largest side, then the triangle is a right angle triangle.

Sum of the two smallest side = 5² + 12²

                                                  = 25 + 144

                                                 = 169

Square of the largest side = 13²

                                           = 169

sum of squares of smallest side =square of the largest side.

So, 5 , 12 , 13 form a right triangle.

Answer:

OptionE)5,12,13

Step-by-step explanation:

If a triangle is a right triangle, then the lengths of its sides satisfy the Pythagorean Theorem, \(a^{2}+b ^{2} =c^{2}\) To determine which choice is correct, test each set of values by substituting them into the Pythagorean Theorem. Start with the first set of numbers: 3, 13, and 14.

\(3^{2} + 13^{2} = 14^{2} \\9+169=196\)

\(178=196\)

Since the result is not a true equality, the first set of values does not represent the side lengths of a right triangle. Test the other four choices. The only values that satisfy the Pythagorean Theorem are 5, 12, and 13.

\(5^{2} +12^{2} = 13^{2} \\25+144=169\\169=169\)

Hence  5,12,and 13 are side lengths of a right triangle

The categorical syllogism "All meticulously constructed timepieces are true works of art" is invalid. A counterexample can be found by considering a meticulously constructed timepiece that lacks aesthetic value.

To use the counterexample method to prove the categorical syllogism "All meticulously constructed timepieces are true works of art, for all Swiss watches are true works of art and all Swiss watches are meticulously constructed timepieces" invalid, we need to find a counterexample that shows the conclusion is false even if the premises are true. Let's consider a scenario in which there is a meticulously constructed timepiece that is not a true work of art. This would be a counterexample to the conclusion, since the conclusion asserts that all meticulously constructed timepieces are true works of art.

For example, suppose that there is a meticulously constructed timepiece that is made with the sole purpose of accurate timekeeping, and has no aesthetic value. This timepiece can be considered a counterexample to the conclusion, since it is meticulously constructed but not a true work of art.

Therefore, the categorical syllogism "All meticulously constructed timepieces are true works of art, for all Swiss watches are true works of art and all Swiss watches are meticulously constructed timepieces" is invalid, since there exist cases where the premises are true but the conclusion is false.

There are 1,000,000 different numeric combination codes that can be set on this lock.

Given that a combination lock has 6 settings, and any digit from 0 to 9 can be selected for each setting with the possibility of repetition, the number of different numeric combination codes that can be set on this lock can be calculated as follows:

Your answer: There are 10 possible digits for each of the 6 settings (0-9). Since each setting is independent and any digit can be repeated, you can simply multiply the number of possibilities for each setting together.

Step 1: Determine the number of possibilities for each setting (0-9) which is 10.
Step 2: Multiply the number of possibilities for all 6 settings: 10 x 10 x 10 x 10 x 10 x 10.

This results in 1,000,000 different numeric combination codes that can be set on this lock.

8) The percent of people that said that Pinocchio was their favorite Disney Movie is of: 28%.

9) The percent of people that said that Pinocchio or Cars was their favorite Disney movie is of: 39%.

10) The two movies that about half the people say were their favorite is of: Pinocchio and Toy Story.

From the pizza graph, the sum of all the percentages must be of 100%, hence the Pinocchio percentage is obtained as follows:

10 + 11 + 14 + 15 + 22 + P = 100

72 + P = 100

P = 100 - 72

P = 28%.

Then the percentage for Pinocchio or Cars is of:

28 + 11 = 39%.

The percentage for Pinocchio or Toy Story is of:

28 + 22 = 50%.

The solutions to the quadratic equation \(2x^2 + 6x - 1 = 0\), obtained by completing the square, are x = -3 + √10 and x = -3 - √10.

To solve the quadratic equation\(2x^2 + 6x - 1 = 0\)by completing the square, follow these steps:

Ensure that the coefficient of \(x^2\) is 1. In this case, it is already 2, so we don't need to make any changes.

Move the constant term to the other side of the equation. Add 1 to both sides:

\(2x^2 + 6x = 1\)

Divide the coefficient of x by 2 and square it. In this case, (6/2)^2 = 9.

Add the result from step 3 to both sides of the equation:

\(2x^2 + 6x + 9 = 1 + 9\)

Simplifying, we get:

\(2x^2 + 6x + 9 = 10\)

Write the left side of the equation as a perfect square trinomial. In this case, it is \((x + 3)^2.\)

\((x + 3)^2 = 10\)

Take the square root of both sides:

\(√[(x + 3)^2] = ±√10\)

Simplifying:

\(x + 3 = ±√10\)

Solve for x by subtracting 3 from both sides:

x = -3 ± √10

So, the solutions to the quadratic equation \(2x^2 + 6x - 1\)= 0, obtained by completing the square, are x = -3 + √10 and x = -3 - √10.

In order to represent the line segment from P to Q by a vector-valued function, we are required to first calculate the vector from P to Q which is then used as the direction of the vector-valued function. The direction vector is found by subtracting the position vectors of Q and P.

We can thus write;` r(t) = P + t(Q-P)`where;

P = (-6, -7, -2) and

Q = (-2, -9, -9)Substituting the above values into the formula we obtain; r(t) = (-6, -7, -2) + t[(-2, -9, -9) - (-6, -7, -2)]

Expanding the brackets, we have;

r(t) = (-6, -7, -2) + t(-2+6, -9+7, -9+2)

r(t) = (-6, -7, -2) + t(4, -2, -7)

Therefore, the vector-valued function of the line segment from P to Q is;r(t) = (-6 + 4t, -7 - 2t, -2 - 7t)

x = -6 + 4t,

y = -7 - 2t,

According to the question of the statement:

Fe = 18

and

"... intake of iron is 18 This is 4 less than twice the recommended daily intake of zinc..."

That is, 18 of Fe is double that of zinc minus 4 units

Writing this situation mathematically:

Answer:

cos(x)=10/15

Step-by-step explanation:

As cosine is Base/Hypotenues

cos(x)=JL/JK

= 10/15

The equation used to find the measure of angle LJK is option C. cos(x) = 10/15.

Trigonometric functions are the functions which are represented as the ratio of the sides of a right angled triangle.

The three main trigonometric functions are sine, cosine and tangent function.

Sine function of an angle is the ratio of the opposite side to the hypotenuse of the triangle.

Cosine function of an angle is the ratio of the adjacent side to the hypotenuse of the triangle.

Here,

Hypotenuse of the triangle = KJ = 15 inches

LJ = 10 inches is the adjacent side with respect to the angle x.

We can use cosine function here.

cos (x) = LJ / KJ = 10/15

Hence the equation used is cos(x) = 10/15.

Sin and Cos formulae are based on the sides of the right-angled triangle. Along with the tan function, the fundamental trigonometric functions in trigonometry are sin and cos. In contrast to the cosine of an angle, which corresponds to the ratio of the adjacent side to the hypotenuse, the sine of an angle is the ratio of the opposing side to the hypotenuse.

Sine of an angle θ = opposite side/hypotenuse
