Applying the sine rule the value of side x is calculated to be 7.4

The size of x is calculated using the sine rule which sates that the ratio of a side and the opposite angles are equal to  each other

This represented by the formula

Sine A / a = Sine B / b = Sine C / c

applying the formula for the problem

Sine A / a = Sine B / b

Sine 29 / 5 = Sine 46 / x

cross multiplying

Since the test statistic (0.1515) is smaller than the crucial value (2.145), we do not reject the null hypothesis.

We need to know the sample size, the difference between the two samples, and the standard deviation in order to calculate the test statistic for the hypothesis test. Using the provided data, we can:

Sample size (n) = 14

Difference (d) = 21

Standard deviation (s) = 518

t = (d - μ) / (s / √n)

So,

t = (21 - 0) / (518 / √14)

t = 21 / (518 / 3.74)

t = 21 / 138.545

t ≈ 0.1515 (rounded to four decimal places)

We do not reject the null hypothesis since the test statistic (0.1155) is smaller than the crucial number (2.145).

Thus, this indicates that, at the 10% significance level, there is insufficient data to draw the conclusion that there is a significant difference between the two delivery services (UPX and INTEX).

Answer:

Step-by-step explanation:

Distance from equipment position to tree base is known. Measured angle of elevation is twenty five degrees. What is the allowed error in the angle measurement?

Two percent of twenty five degrees is

2/100 × 25 = 0.02 × 25 = 0.5

This is the allowed error in the angle measurement - 0.5 degrees

Hence, the angle could or should fall anywhere between 24.5 and 25.5

These two figures are gotten by subtracting 0.5 from 25 and by adding 0.5 to 25 respectively.

The allowed error in the angle measurement is 0.5 degrees.

The closest probability to that a randomly chosen task will take less than 34 minutes or more than 60 minutes to complete is 0.0303. Hence, the option that is closest to 0.0303 is b. 0.0303.

The probability that a randomly selected task will take less than 34 minutes is equal to P (X <34).

Here, the given data is

Mean (μ) = 47 minutes

Standard deviation (σ) = 6 minutes

So, the standardized value of 34 minutes =z

1 = (34 - 47) / 6 = - 2.1667

The probability that a randomly chosen task will take more than 60 minutes to complete is equal to P (X> 60).

Here, the given data is

Mean (μ) = 47 minutes

Standard deviation (σ) = 6 minutes

So, the standardized value of 60 minutes =z

2 = (60 - 47) / 6 = 2.1667

Thus, we need to find the probability that a randomly selected task will take less than 34 minutes or more than 60 minutes to complete. That is, we need to find the probability of the union of the two events P (X <34) ∪ P (X> 60).Using the standard normal table, we can find

P (X <34) = P (Z <−2.1667)

               = 0.0151

P (X> 60) = P (Z> 2.1667)

               = 0.0151

Therefore, P (X <34) ∪ P (X> 60) = P (X <34) + P (X> 60) - P (X <34 ∩ X> 60)0.0151 + 0.0151 - 0

                                                     = 0.0302

  R: {-8, 0, 1, 5}

The range is the list of second numbers of the ordered pairs: {-8, 0, 1, 5}.

The average score of all students, calculated by taking a weighted average based on the number of students in each group, is 38. The overall performance is slightly below the group averages.

The average score of students in the first, second, and third groups are 39, 32, and 43, respectively. There are 24 students in the first group, 26 students in the second group, and 27 students in the third group.

To find the average score of all students, we need to take a weighted average of the scores in each group, with the number of students in each group as the weights.

Here's how to do it: First, we calculate the total number of students:24 + 26 + 27 = 77. Then, we calculate the total score across all students: 39*24 + 32*26 + 43*27 = 936 + 832 + 1161 = 2929

Finally, we divide the total score by the total number of students to get the average score:2929/77 = 38. The average score of all students is 38.

This means that the overall performance of all the students is slightly below the average of the scores in each group.

Step-by-step explanation:

The absolute value is the distance of the point from 0. In this question, it would be the number itself.

Answer:

The answer would be 8 and 18

Step-by-step explanation:

To solve an equation containing absolute value, isolate the absolute value on one side of the equation. Then set its contents equal to both the positive and negative value of the number on the other side of the equation and solve both equations. Solve | x | + 2 = 5. Isolate the absolute value.

The Steady-state gain can be found using the formula Kp = lim s->0 G(s).

A. (a) The inverse Laplace transform of the function 8 /s² (s+2) is given by f(t) = 8(t - e^(-2t)).

B. (a) To find the inverse Laplace transform of 8 /s² (s+2), we can use partial fraction decomposition and inverse Laplace transform tables.

First, we express the function in partial fraction form as follows: 8 /s² (s+2) = A/s + B/s² + C/(s+2).

To find the values of A, B, and C, we can equate the coefficients of corresponding powers of s in the numerator and denominator. This leads to the equations A + 2B + 2C = 0, A = 8, and B = -8.

Substituting the values of A and B into the equation A + 2B + 2C = 0, we find C = 4.

Now, we have the partial fraction decomposition as: 8 /s² (s+2) = 8/s - 8/s² + 4/(s+2).

Using inverse Laplace transform tables, we find the inverse Laplace transforms of each term: L⁻¹{8/s} = 8, L⁻¹{8/s²} = 8t, and L⁻¹{4/(s+2)} = 4e^(-2t).

Finally, we combine the inverse Laplace transforms of each term to obtain the inverse Laplace transform of the original function: f(t) = 8(t - e^(-2t)).

Step-by-step explanation:

Given

Coins = 20

Value = $3.05

Required

Determine the equation that represent this

From the question, we have that

d = the number of dimes

q = the number of quarters

This implies that;

\(d + q = 20\)

Also;

\(1 d=\$0.25\ \ and\ \\1 q= \$0.10\)---------- Standard unit of conversion;

This implies that

\(0.25d + 0.10q = 3.05\)

Hence, the equations are:

\(d + q = 20\)

\(0.25d + 0.10q = 3.05\)

Answer:D 3,215.36 square feet. 1.9m. 2)

Step-by-step explanation:

Answer:

perimeter = 54.08

Step-by-step explanation:

We are told that the area of a square kitchen is 182.25 m². We are then asked to calculate the perimeter of the kitchen.

The perimeter of a shape is simply the sum of the length of its sides. Therefore, in order to calculate the perimeter of the kitchen, we need to know the length of its sides.

Given that we know the area of the square kitchen, we can use the formula:

\(\boxed{\mathrm{Area = side^2}}\),

and rearrange it to make the side the subject:

Area = side²

⇒ \(182.25 = \mathrm{side^2}\)

⇒ \(\sqrt{182.85} = \mathrm{\sqrt{side^2}}\)         (taking the square root of each side)

⇒ \(13.52 = \mathrm{side}\)

⇒  side = 13.52 m

Therefore, the length of each side of the square kitchen is 13.52 m.

A square has 4 sides; therefore the perimeter of the kitchen can be calculated as follows:

perimeter = \(4 \times 13.52\)

                 = \(\bf 54.08 \ m\)

Therefore, the perimeter of the square kitchen is 54.08 m.

Based on the information provided, we know that m<5 has a measure of 64 degrees and m<6 can be represented as 3x-25.

In order to find the value of x, we need to solve for x in the equation 3x-25=m<6. Since we know that m<6 is equal to (3x-25), we can substitute this expression in the equation to get 3x-25=(3x-25).

By simplifying this equation, we get 3x=3x, which means that x can be any value since the equation is true for all x values. Therefore, we cannot determine the specific value of x based on the given information.

It's important to remember that when solving for unknown angles or variables, we need to use the equations and information given to us and make sure to simplify the equations as much as possible to get a clearer understanding of the problem.
