A school newspaper estimates that their academic team will win 25 out of 30 matches for the season. After 15 matches, they have won 12. If the team continues winning at this rate, what will be the percent error of the newspaper's estimate once the season is over? Round to the nearest percent
Answer:
4
Step-by-step explanation:
The percent error of the newspaper's estimate once the season is over will be 4%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
A school newspaper estimates that their academic team will win 25 out of 30 matches for the season.
Then the percentage will be given as,
P = (25 / 30) x 100
P = 0.8333 x 10
P = 83.33%
After 15 matches, they won 12. Then the percentage will be given as,
P = (12 / 15) x 100
P = 0.80 x 100
P = 80%
If the team continues winning at this rate. Then the percent error of the newspaper's estimate once the season is over will be
P = [(83.33 - 80) / (83.33)] x 100
P = 0.04 x 100
P = 4%

Step-by-step explanation:
Derrick really wants to earn at least $330 at the Bike Shop this week before he goes on vacation. He earns $150 in a week plus $20 for each bicycle he assembles. Which inequality would help Derrick determine how many bicycles (b) he needs to put together?
Answer:
150 + 20x ≥ 330
Step-by-step explanation:
"At least" indicates that you should use the greater than or equal to sign. His weekly wage and the bicycle assembly money when added must be at least 330, so 150 and 20x are on the same side. The 20x represents the $20 for each bicycle multiplied by the amount of bicycles he assembled.

Find the length of line segment UV.
Answer:
The length of the line segment UV is 76 units
Step-by-step explanation:
In a triangle, the line segment joining the mid-points of two sides is parallel to the third side and equal to half its length
In Δ ONT
∵ U is the mid-point of ON
∵ V is the mid-point of TN
→ That means UV is joining the mid-points of two sides
∴ UV // OT
∴ UV = [tex]\frac{1}{2}[/tex] OT
∵ UV = 7x - 8
∵ OT = 12x + 8
∴ 7x - 8 = [tex]\frac{1}{2}[/tex] (12x + 8)
→ Multiply the bracket by [tex]\frac{1}{2}[/tex]
∵ [tex]\frac{1}{2}[/tex] (12x + 8) = [tex]\frac{1}{2}[/tex] (12x) + [tex]\frac{1}{2}[/tex] (8) = 6x + 4
∴ 7x - 8 = 6x + 4
→ Add 8 to both sides
∴ 7x - 8 + 8 = 6x + 4 + 8
∴ 7x = 6x + 12
→ Subtract 6x from both sides
∴ 7x - 6x = 6x - 6x + 12
∴ x = 12
→ Substitute the value of x in the expression of UV to find it
∵ UV = 7(12) - 8 = 84 - 8
∴ UV = 76
∴ The length of the line segment UV is 76 units
What is the x-intercept of the line?
(22,36)
(27,54)
(32,72)
Answer:
12
Step-by-step explanation:
the equation of the line is y=18/5x-216/5 and then find the x intercept and that is 12
The x-intercept of the line is 1.
The line intersects the x-axis at the point (1, 0).
Here,
To find the x-intercept of a line, we need to identify the point at which the line intersects the x-axis.
At the x-intercept, the y-coordinate is always 0.
Let's use the given data to find the equation of the line first using two points (x, y):
Using (22, 36) and (27, 54):
Calculate the slope (m) of the line:
m = (change in y) / (change in x) = (54 - 36) / (27 - 22) = 18 / 5
Use the slope and one of the points to find the equation of the line
(y = mx + b).
Let's use (22, 36):
36 = (18/5) * 22 + b
36 = 39.6 + b
b = 36 - 39.6
b = -3.6
So, the equation of the line is y = (18/5)x - 3.6.
Now, to find the x-intercept (where y = 0), we can set y = 0 in the equation and solve for x:
0 = (18/5)x - 3.6
(18/5)x = 3.6
x = 3.6 * 5 / 18
x = 1
Therefore, the x-intercept of the line is 1.
The line intersects the x-axis at the point (1, 0).

A river flows due south at 1.4 mi/h. In what direction should the swimmer head, at a velocity of 3 mi/h, in order to arrive at a landing point due east of his starting point? (Round your answer to one decimal place.)
Solution:
It is that a river is flowing in the south direction with a speed of [tex]$v_r$[/tex]1.4 mi/h.
A swimmer wishes to cross the river in a horizontal direction so that he lands at a point which is due east of his starting point.
The speed of the swimmer is [tex]$v_s$[/tex] = 3 mi/h
Therefore he has to swim in such a direction that his resultant is in the direction east to his starting point.
Let this angle be θ.
Therefore, from the figure,
[tex]$\sin \theta = \frac{v_r}{v_s}$[/tex]
[tex]$\sin \theta = \frac{1.4}{3}$[/tex]
[tex]$\theta = \sin^{-1}(0.46)$[/tex]
[tex]$=27.4^\circ[/tex]
Therefore, the swimmer has to swim in the northeast direction making an angle of (90+27.4) = 117.4° with the direction of flow of river (i.e. south).

Step-by-step explanation:
The number of employees per department are normally distributed with a population standard deviation of 198 employees and an unknown population mean. If a random sample of 22 departments is taken and results in a sample mean of 1460 employees, find the error bound (EBM) of the confidence interval with a 80% confidence level.
Answer:
EBM = +-54.126
Step-by-step explanation:
In this question we have confidence interval to be 80%
The formula to solve this is in the attachment.
Bar X = 1460
Z-alpha/2 = 1.282
Sd = standard deviation = 198 employees
n = 22 departments
After we have inserted all values in to the formula we have:
1460 +-(1.282*198/√22)
= 1460+-(54.12604)
= (1405.87, 1514.126)
The error bounded mean EBM
= +-z-alpha/2 x (sd/√n)
= 1.282 x 198/√22
= 1.282 x 42.22
EBM = +-54.126
