Select the correct answer. The velocity of a train relative to the ground is represented by the distance from A to B in the diagram. The velocity of a ball thrown inside the train at an angle of 66° relative to the train is represented by the distance from B to C. What is the distance from A to C (the velocity of the ball relative to the ground), correct to two decimal places? Assume that all the points in the diagram lie in the same plane. A. 21.14 m/s B. 18.03 m/s C. 17.20 m/s D. 15.00 m/s
A and C are separated by 21.14 miles. The right answer is A.
What is trigonometry?Trigonometry is a branch of mathematics, which deals with the study of right angle triangles. Trigonometry is concerned with specified functions of angles and their applications to calculations.
The ratio of the object's distance travelled at a certain time is known as its velocity. As a vector quantity, the velocity requires both the magnitude and the direction.
Assuming that the distance from A to B in the diagram represents the train's speed in relation to the ground. The distance from B to C represents the velocity of a ball thrown inside a train at an angle of 66° to the train.
The following formula will be used to determine how far A is from C:
2×15×10×cos(180-66)=15²+10²-AC²
-300 cos 66=225+100-AC²
AC=√(325+300 cos 66)
AC = 21.17 m/s
As a result, A and C are separated by 21.14 miles. The right

The manager of the customer service department of an e-commerce company wants to know the average hold time for customers who call the department. The department receives about 850 calls each hour. The following data set shows the hold time, in minutes, for 10 calls picked at random. 2,1,4,5,3,3,7,4,3,2. Calculate the approximate hold time for all customers who call the customer service department.
The approximate hold time for all customers who call the customer service department is A 4 minutes. B 3 minutes. cannot be calculated from the given data. d 7 minutes
Answer:
The answer is approximately 3.
Step-by-step explanation:
You add all the numbers and then divide by 10
The approximate hold time for all customers who call the customer service department is 3 minutes.
What is a mean?Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
For the given situation,
The department receives about 850 calls each hour.
The data set shows the hold time, in minutes, for 10 calls picked at random. 2,1,4,5,3,3,7,4,3,2.
The approximate hold time for all customers who call the customer service department is calculated by mean as
⇒ [tex]\frac{sum of number of data sets}{Total number of data sets}[/tex]
⇒ [tex]\frac{2+1+4+5+3+3+7+4+3+2}{10}[/tex]
⇒ [tex]\frac{34}{10}[/tex]
⇒ [tex]3.4[/tex] ≈ [tex]3[/tex]

PLEASEEEE HELP I WILL MAKE YOU BRAINIEST
Answer:
14
Step-by-step explanation:
Because right angles are 90 degrees, we need to subtract 34 from 90 which gets us 56. That means 56 = 4x, so 56/4 = 14, therefore X = 14.
Hope this helps!
Both angles form a right angle which is 90 degrees.
Angle 2 would equal 90 degrees - angle 1
Angle 2 = 90 -34 = 56
So now we know 4x = 56
To find x divide both sides by 4
X = 14

This question is incomplete, the complete question is;
Suppose an experiment is done with criminals released from prison in a certain state where the recidivism rate is 37%; that is, 37% of criminals return to prison within three years.
One hundred random prisoners are made to attend a "boot camp" for two weeks before their release, and it is hoped that "boot camp" will have a good effect. Suppose 32 of those prisoners return to prison within three years. The null hypothesis is that those attending boot camp have a recidivism rate of 37%.
a) what is p. sample proportion of successes?
b) what is p0, the hypothetical proportion of success under the null hypothesis
c) what is the value of test statistic
Answer:
a) sample proportion of successes is 0.32
b) the required value of p₀ is 0.37
c) the required test statistics value is -1.0356
Step-by-step explanation:
Given the data in the question
100 prisoners attend boot camp and 32 of them return to prison within three years
x = 32
n = 100
recidivism rate for the whole state = 37% = 0.37
a)
what is p. sample proportion of successes
p" = x / n
we substitute
p" = 32 / 100
p" = 0.32
Therefore, sample proportion of successes is 0.32
b)
what is p₀, the hypothetical proportion of success under the null hypothesis
given that;
the population recidivism rate for the whole state is 37%;
p₀ = 37%
p₀ = 0.37
Therefore, the required value of p₀ is 0.37
Null hypothesis H₀ : p₀ = 0.37
Alternative hypothesis Hₐ : p₀ ≠ 0.37
c)
what is the value of test statistic
Z = (p" - p₀) / √([tex]\frac{p_0(1-p_0)}{n}[/tex])
so we substitute
= (0.32 - 37) / √([tex]\frac{0.37(1-0.37)}{100}[/tex])
= -0.05 / √0.002331
= -0.05 / 0.04828
= -1.0356
Therefore, the required test statistics value is -1.0356

Jose purchased a delivery van for his business through an online auction. His winning bid for the van was $34,750. In addition, Jose incurred the following expenses before using the van: shipping costs of $1,470; paint to match the other fleet vehicles at a cost of $1,590; registration costs of $4,836, which included $4,600 of sales tax and an annual registration fee of $236; wash and detailing for $141; and an engine tune-up for $318.
Required:
What is Jose’s cost basis for the delivery van?
Answer:
Jose's cost basis for the delivery van = $42,410
Step-by-step explanation:
Cost basis of a fixed asset can be described the original value of an asset for tax purposes which includes the purchase price, shipping, installation, sales tax, and other costs incurred that are related to the purchase of the fixed asset and to make it be in conformity with other assets in its class.
Based on this explanation, Jose's cost basis for the delivery van can be calculated as follows:
Jose's cost basis for the delivery van = Winning bid + Shipping costs + Cost of painting to match other fleet vehicles + Sales tax = $34,750 + $1,470 + $1,590 + $4,600 = $42,410

(q4)Find the area of the region bounded by the graphs of
and x = y - 4.
The area of the region bounded by the graphs is 3.33 .Option B
To find the area of the region bounded by the graphs, we need to determine the points of intersection and integrate the appropriate functions within the bounds.
First, let's find the points of intersection between the graphs.
Setting the equations equal to each other, we have:
x = y - 4
x = ±√(y - 2)
To solve this system of equations, we can square both sides of the second equation:
[tex]x^2 = y - 2[/tex]
Now, we can substitute x from the first equation into the squared equation:
[tex](y - 4)^2 = y - 2[/tex]
Expanding and rearranging the equation:
[tex]y^2 - 8y + 16 = y - 2\\y^2 - 9y + 18 = 0[/tex]
Factoring the quadratic equation:
(y - 3)(y - 6) = 0
So we have two solutions: y = 3 and y = 6.
Now, let's find the corresponding x-values for each y-value.
For y = 3:
x = y - 4 = 3 - 4 = -1
For y = 6:
x = y - 4 = 6 - 4 = 2
We have found the points of intersection: (-1, 3) and (2, 6).
To find the area, we need to integrate the appropriate functions within the bounds.
For the first part of the region, bounded by the graphs x = y - 4 and x = -√(y - 2), we integrate with respect to y:
A1 = ∫[3, 6] [(y - 4) - (-√(y - 2))] dy
Simplifying:
A1 = ∫[3, 6] [y - 4 + √(y - 2)] dy
To evaluate this integral, we need to use numerical methods or software. The result is approximately 2.08 sq. units.
For the second part of the region, bounded by the graphs x = y - 4 and x = √(y - 2), we integrate with respect to y:
A2 = ∫[3, 6] [(y - 4) - √(y - 2)] dy
Simplifying:
A2 = ∫[3, 6] [y - 4 - √(y - 2)] dy
Again, we need to use numerical methods or software to evaluate this integral. The result is approximately 1.25 sq. units.
Finally, we find the total area by adding A1 and A2:
Total area = A1 + A2 = 2.08 + 1.25 = 3.33 sq. units.Therefore, the correct answer is Option B
