Answer:

The answer would be A/B=H

Step-by-step explanation:

To get rid of the B that is connected to the H, you would do the opposite of what they used. Meaning since the two were multiplied you would divide them. So, you would take your b and divide it on both sides of the equal sign. B and B cancels each other out so you are left with A/B which equals H.

The correct answer is: c) 1/3, 5/3 The cosine function has a period of 2π, meaning it repeats every 2π radians.

To find the solutions for x in the equation 12cos(2x) + 10 = 16, we can solve it algebraically. Let's begin:

12cos(2x) + 10 = 16

Subtract 10 from both sides:

12cos(2x) = 6

Divide both sides by 12:

cos(2x) = 1/2

Now, we want to find the two smallest positive solutions for cos(2x) = 1/2. The cosine function has a period of 2π, meaning it repeats every 2π radians. We are looking for solutions in the range of 0 to 2π.

The cosine function has values of 1/2 at two specific angles: π/3 and 5π/3.

So, we can set up the following equations:

2x = π/3 and 2x = 5π/3

Solving for x in each equation:

For 2x = π/3:

x = π/6

For 2x = 5π/3:

x = 5π/6

Thus, the two smallest positive solutions for x in the equation 12cos(2x) + 10 = 16 are x = π/6 and x = 5π/6.

Therefore, the correct answer is:

c) 1/3, 5/3

The expected value for X is 1.56.

Expected value is the mean value that we would expect if we conducted the same experiment many times and recorded the result of each trial. This formula is used to calculate the expected value for X.

This formula is used to calculate the expected value for X:E(X) = Σ [ xi * P(xi) ] where xi represents the value of X, and P(xi) is the probability of X taking the value xi.

The value of xi is multiplied by its corresponding probability and then summed over all the values of X.

This gives the expected value of X. Now, let us use the formula to calculate the expected value of X:

E(X) = (0 * 0.10) + (1 * 0.05) + (2 * 0.02) + (1 * 0.12) + (0 * 0.10) + (2 * 0.10) + (3 * 0.16) + (0 * 0.06) + (1 * 0.11) + (2 * 0.28)E(X) = 0 + 0.05 + 0.04 + 0.12 + 0 + 0.20 + 0.48 + 0 + 0.11 + 0.56E(X) = 1.56

Answer:

x = 10, y = - 9

Step-by-step explanation:

Given the 2 equations

x = - 3y - 17 → (1)

2x + 3y = - 7 → (2)

Substitute x = - 3y - 17 into (2)

2(- 3y - 17) + 3y = - 7 ← distribute and simplify left side

- 6y - 34 + 3y = - 7

- 3y - 34 = - 7 ( add 34 to both sides )

- 3y = 27 ( divide both sides by - 3 )

y = - 9

Substitute y = - 9 into (1) for corresponding value of x

x = - 3(- 9) - 17 = 27 - 17 = 10

[tex]7:4:2[/tex]

Step-by-step explanation:

Assign variables for the 3 numbers. Let the first number be x, the second number be y, and the third number be z.

"The sum of the 3 numbers is 145", therefore:

"Seven times the second number is twice the first number":

"Twice the second number is six times the third number":

We can solve for x, y and z using this system of equations. Let's solve for y in the first equation by putting the other variables in terms of y in Equations II and III.

Solve for x in [tex]\text{Equation II}[/tex]:

Solve for z in [tex]\text{Equation III}[/tex]:

Substitute these values into [tex]\text{Equation I}[/tex] to solve for y.

Combine like terms using common denominators. The least common denominator is 6. Multiply [tex]\frac{7}{2} y[/tex] by [tex]\frac{3}{3}[/tex], multiply [tex]y[/tex] by [tex]\frac{6}{6}[/tex], and multiply [tex]\frac{1}{3} y[/tex] by [tex]\frac{2}{2}[/tex] to make all of the denominators = 6.

Add the fractions together.

Solve for y by multiplying both sides by [tex]\frac{6}{29}[/tex].

We have found that y = 30. Now we can use this known value in order to solve for both x and z in Equations II and III.

[tex]\text{Equation II}:[/tex]

[tex]\text{Equation III}:[/tex]

We have found that x = 105, y = 30, and z = 10. Now we can write the new ratio of these 3 numbers:

"Write the new ratio of the three numbers if the second number doubles and the third number is increased by one less than one fifth of the first number":

The question asks for the new ratio once we evaluate these expressions. The variable x is the only one that stays the same at the end: 105.

Our final numbers are x = 105, y = 60, and z = 30. We can create the ratio between these numbers by fully simplifying them. Right now we have [tex]x:y:z=105:60:30[/tex]. Start by dividing all of the numbers by 5.

We get [tex]21:12:6[/tex]. This ratio can be simplified further by dividing all of the numbers by 3. We then get the ratio of: [tex]7:4:2[/tex].

This ratio cannot be simplified any further, therefore, it is the new ratio of the three numbers.

Based on the provided table, we can calculate the project length, identify the activities on the critical path, and determine the slack for activities A and B.

a. To calculate the project length, we need to determine the longest path through the project network.

This path is known as the critical path and represents the minimum time required to complete the project.

By summing up the durations of all activities on the critical path, we can find the project length.

b. Activities on the critical path are those that directly contribute to the project length. Any delay in these activities would cause a delay in the overall project completion.

By analyzing the dependencies and durations of the activities, we can identify which ones fall on the critical path.

c. Slack refers to the amount of time an activity can be delayed without delaying the project's overall completion. It is calculated by finding the difference between the latest start time and the earliest start time for each activity. For activities A and B, we can determine the slack by comparing their earliest and latest start times.

By performing the necessary calculations and analysis, we can provide the specific answers for the project length, critical path activities, and the amount of slack for activities A and B.

In an F-test, the null hypothesis typically states that all specified coefficients are equal to zero. In this case, the null hypothesis is:

H0: β1 = 0, β2 = 0, βs = 0, and β4 = 0

To reject the null hypothesis, we need to find evidence that at least one of these restrictions is violated. This means that if we can show that any one of the coefficients (β1, β2, βs, or β4) is significantly different from zero, it would provide sufficient evidence to reject the null hypothesis.

Therefore, if any one of these restrictions is violated, meaning that its corresponding coefficient is not equal to zero, it would lead to rejecting the null hypothesis. In this case, only one violation among β1, β2, βs, or β4 is needed to reject the null hypothesis. Hence, the correct answer is:

(b) 1

It's important to note that the specific restriction that is violated can be different for each case, but as long as one restriction is violated, we have enough evidence to reject the null hypothesis in an F-test.

d) Rolling an even number that is less than 2 is not a valid outcome when rolling a die.therefore, option d) is correct.

The outcome that is not possible is (d) rolling an even number that is less than 2 on a die.

A standard die has six sides numbered from 1 to 6, and all the even numbers on a standard die are 2, 4, and 6.

The statement "rolling an even number that is less than 2" contradicts the fact that the lowest even number on a die is 2.

Thus, it is not possible to roll an even number that is less than 2 on a standard die, making it an invalid outcome.

Answer: the slope is m = 3/5 and the

y-intercept point:  (0 , [tex]-\frac{13}{5}[/tex] )

Step-by-step explanation:

Answer:

Slope: 3/5, y-intercept: -13/5

Step-by-step explanation:

In slope intercept form (y=mx+b), the slope is the coefficient in front of x (m), and the y intercept is b. Let's simply the equation into slope intercept to find the slope and y intercept.

3x - 5y = 13

-5y = -3x + 13

y = 3/5x - 13/5

So the slope is 3/5 and the y-intercept is -13/5

The area of the region under the parabola y = 5x - x^2, where 1 ≤ x ≤ 4, is 14.33 square units.

To find the area under the parabola, we need to integrate the equation y = 5x - x^2 with respect to x over the given interval [1, 4]. The integral represents the area between the curve and the x-axis.

Integrating y = 5x - x^2 gives us the antiderivative F(x) = (5/2)x^2 - (1/3)x^3 + C, where C is the constant of integration. To find the definite integral over the interval [1, 4], we evaluate F(4) - F(1).

F(4) = (5/2)(4)^2 - (1/3)(4)^3 + C = 40 - (64/3) + C

F(1) = (5/2)(1)^2 - (1/3)(1)^3 + C = 5 - (1/3) + C

Substituting these values into the definite integral expression, we have:

Area = F(4) - F(1) = (40 - (64/3) + C) - (5 - (1/3) + C)

= 14.33

The area of the region under the parabola y = 5x - x^2, where 1 ≤ x ≤ 4, is approximately 14.33 square units.
