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.

Q15) E. The standard deviation of the scores is , 1.93.

Q16, A) X(2X + 2Y) = 2.

Q17, B)  EXY = 3.5.

Q18, C) The Mean of X scores is 0.

Q19, D) The value of (X - 2) is -3, -6, 3, 0, -3, -2, -2, -2.

Q15.E)  For the standard deviation of the scores, we need to first compute the mean of the scores.

Mean of scores = (-1 -4 + 5 + 2 -1 + 0 + 0 + 0) / 8

                        = 0

Now, we need to find the difference between each score and the mean, square each difference, and take the average of all the squared differences.

(X - Mean): 1 16 25 4 1 0 0 0

Adding up all the squared differences and dividing by the total number of scores:

Sum ((X - Mean)) / n

= (1 + 16 + 25 + 4 + 1 + 0 + 0 + 0) / 8

sum((X - Mean)) / n = 47 / 8

Finally, taking the square root of this value gives us the standard deviation:

Standard deviation = √(sum((X - Mean)) / n) = √(47 / 8) = 1.93

Therefore, the standard deviation of the scores is , 1.93.

Q16, A) Now, For the value of X(2X + 2Y), we need to first find the value of 2X + 2Y, and then multiply it by X.

2X + 2Y = 2(X + Y)

Now, substituting the given values of X and Y:

2X + 2Y = 2(-1 -4 + 5 + 2 -1 + 0 + 0 + 0)

2X + 2Y = 2(1)

2X + 2Y = 2

Finally, multiplying this value by X:

X(2X + 2Y) = 1(2) = 2

Therefore, X(2X + 2Y) = 2.

Q17. B. For the value of EXY, we need to first find the product of each X and Y pair, and then take the average of all the products.

X Y XY -1 -4 4 5 2 10 -1 0 0 0 0 0

Now, adding up all the XY values and dividing by the total number of pairs:

EXY = (4 + 10 + 0 + 0) / 4 = 3.5

Therefore, EXY = 3.5.

Q18. C. For the Mean of the X scores, we simply need to take the average of all the X values.

Mean of X scores = (-1 -4 + 5 + 2 -1 + 0 + 0 + 0) / 8

                           = 0

Therefore, the Mean of X scores is 0.

Q19. D. For the value of (X - 2), we simply need to subtract 2 from each of the X values. X - 2:

-3 -6 3 0 -3 -2 -2 -2

Therefore, (X - 2) is -3, -6, 3, 0, -3, -2, -2, -2.

The smallest possible inside length of the cubical steel tank that can hold 275 liters of water is approximately 0.640 meters.

The side length of the cube is found by converting the volume of water from liters to cubic meters, as the unit of measurement for the side length is meters.

Given that the volume of water is 275 liters, we convert it to cubic meters by dividing it by 1000 (1 cubic meter = 1000 liters):

275 liters / 1000 = 0.275 cubic meters

Since a cube has equal side lengths, we find the side length by taking the cube root of the volume. In this case, we find the cube root of 0.275 cubic meters:

∛(0.275) ≈ 0.640

Rounded to the nearest 0.001 meters, the smallest possible inside length of the tank is approximately 0.640 meters.

Answer:

A) A = 180 in

B) V = 144 in³

Step-by-step explanation:

A = 2 ( wl + hl + wh)

A = 2 (3 × 8) + (6 × 8) + (3 × 6)

A = 2 [(24) + (48) + (18)]

A = 2 × (90)

A = 180 in

V = w × h × l

V = 3 × 6 × 8

V = 144 in³

The fraction of KM that is required to obtain 20% Vmax is [S] = 0.2 KM.

The Michaelis-Menten equation is given by: V = Vmax[S] / (KM + [S])where, V is the velocity of the reaction, Vmax is the maximum velocity of the reaction,[S] is the substrate concentration, and KM is the Michaelis constant of the enzyme.

Substituting V = 0.2V

max and rearranging the equation,

0.2Vmax = Vmax[S] / (KM + [S])

Multiplying both sides by

(KM + [S]),0.2V

max(KM + [S]) = Vmax[S]

Expanding the equation,

0.2VmaxKM + 0.2Vmax[S]

= Vmax[S]0.2VmaxKM

= 0.8Vmax[S]

Dividing both sides by

Vmax,0.2KM = 0.8[S]

Simplifying the equation,

[S] = 0.2 KM / 0.8[S] = 0.25 KM

Therefore, the fraction of KM that is required to obtain 20% Vmax is [S] = 0.2 KM, which is option (a).

If 09 people can complete the job in 75 days then 25 people needs 45 days to complete the job.

Let T be the time and L be the Labor (Number of people working on the bridge).

T ∞ 1/√L  (Inverse relationship)

T = K/√L                   ----------------------------- (1)

Since, Constant "K" is introduced once the variation sign (∞) changes to equality (=) sign.

According to the question,

Time (T) = 75 days    and

labor (L) = 09

From the equation (1), we get,

    T = K / √L

⇒ 75   = K/√9

⇒ 75= K/3

⇒ K= 225

First, the relationship between these variables is:

                       T = 225/√L

Therefore, how long it will take 25 people to do it means that we should look for the time.

                           T=225/√L

                      ⇒  T= 225/√25

                      ⇒  T= 225/5

                      ⇒  T= 45 days.

Answer:

Step-by-step explanation:

The requreid equation of the circle is \((x + 5)^2 + (y + 3)^2 = 17^2\).

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

Where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.

Here,
the center is (-5, -3), so we have:

(x - (-5))² + (y - (-3))² = r²

Simplifying, we get:

(x + 5)² + (y + 3)² = r²

We also know that the circle contains the point (3, -18). Substituting this point into the equation of the circle, we get:

(3 + 5)² + (-18 + 3)² = r²

Simplifying, we get:

8² + (-15)^2 = r²

64 + 225 = r²

289 = r²

Taking the square root of both sides, we get:

r = 17

Therefore, the equation of the circle is:

\((x + 5)^2 + (y + 3)^2 = 17^2\)

or

\(x^2 + 10x + y^2 + 6y + 9 = 289\)

The percentage of decrease in the number of students admitted to the university from 4,362 to 3,720 is approximately 14.7% when rounded to the nearest tenth.

To find the percentage of decrease, we use the formula:

Percentage of decrease = ((Initial value - Final value) / Initial value) * 100

In this case, the initial value is 4,362 students and the final value is 3,720 students. Substituting these values into the formula, we have:

Percentage of decrease = ((4,362 - 3,720) / 4,362) * 100

Simplifying the expression gives:

Percentage of decrease = (642 / 4,362) * 100

Calculating the numerical result yields:

Percentage of decrease ≈ 0.1472 * 100

Rounding the result to the nearest tenth, we get approximately 14.7%.

The percentage of decrease in the number of students admitted to the university is approximately 14.7%. This means that there was a reduction of about 14.7% in the student population from the initial value of 4,362 to the final value of 3,720.

Answer:

Possible expressions for the radius of the can and the depth of the paint in the can are \(r = \sqrt{9\cdot x^{2}+24\cdot x+16}\) and \(h = 2\cdot x\), respectively.

Step-by-step explanation:

Let be the initial volumes of the initial cans represented by these expressions:

\(V_{1} = (8\cdot x^{3}+31\cdot x^{2}+32\cdot x)\cdot \pi\) (1)

\(V_{2} = (10\cdot x^{3}+17\cdot x^{2})\cdot \pi\) (2)

The resulting volume of the paint can is the sum of the two functions:

\(V_{3} = (18\cdot x^{3}+48\cdot x^{2}+32\cdot x)\cdot \pi\) (3)

Then, we proceed to factor the polynomial:

\(V_{3} = 2\cdot (9\cdot x^{2}+24\cdot x +16)\cdot x \cdot \pi\)

\(V_{3} = \pi\cdot (9\cdot x^{2}+24\cdot x + 16)\cdot (2\cdot x)\) (3b)

By direct comparison with the volume formula for the cylinder we have the following expressions:

\(r^{2} = 9\cdot x^{2}+24\cdot x + 16\)

\(r = \sqrt{9\cdot x^{2}+24\cdot x+16}\)

\(h = 2\cdot x\)

Possible expressions for the radius of the can and the depth of the paint in the can are \(r = \sqrt{9\cdot x^{2}+24\cdot x+16}\) and \(h = 2\cdot x\), respectively.

This function takes an input value x, multiplies it by 2, and then adds 1 to it. The result is the corresponding output value, denoted as f(x).

To prove that for a linear function, f(0) = 0, we can use the general form of a linear function, which is f(x) = mx + b, where m is the slope and b is the y-intercept.

When x = 0, the equation becomes f(0) = m(0) + b = b. Since b represents the y-intercept, it is the value of y when x = 0.

If f(0) = b, then for a linear function, the y-intercept is the value of f(0). Since we want to prove that f(0) = 0, it means that the y-intercept, b, must be equal to 0.

Therefore, for a linear function, f(0) = 0.

A function is a mathematical relationship between two sets of elements, known as the domain and the codomain, that assigns each element from the domain to a unique element in the codomain. In simpler terms, a function takes an input value and produces a corresponding output value.

A function is typically denoted by a symbol, such as f(x), where f represents the name of the function and x is the input variable. The output of the function, also known as the function value or the image of x, is denoted as f(x) or y.

Here's an example to illustrate a function:
