The number of seats in the two buses are: first bus includes 27 seats and second bus includes 108 seats.
What is proportion?An equation known as proportion shows that the two ratios presented are equal to one another. For instance, the time it takes a train to go 100 kilometres per hour is equal to the time it needs to travel 500 kilometres in five hours. Example: 100 km/hr = 500 km/5 hour.
Given that:
Three rows of nine seats each make up one bus, hence the first bus's seating arrangement is as follows:
3 x 9 = 27.
Since the other bus has four times as many seats as the first bus, the second bus's seat count is as follows:
4 x 27 = 108.
Hence, the number in the two buses are first bus includes 27 seats and second bus includes 108 seats.

You take one ball randomly from a bag with 10 yellow, 5 orange and 5 green balls. What is the probability that you don’t take a yellow ball.
0
1
1/2
Can not be determined
Answer: The probability of not taking a yellow ball can be found by using the formula:
Probability of event A = (Number of favorable outcomes) / (Total number of outcomes)
In this case, the event of not taking a yellow ball is the favorable outcome, and the total number of outcomes is the total number of balls in the bag, which is 10 yellow, 5 orange, and 5 green balls. So, the total number of outcomes is 20.
The number of balls that are not yellow is 5 orange + 5 green = 10.
So, the probability of not taking a yellow ball is
Probability of not taking a yellow ball = (Number of non-yellow balls) / (Total number of balls) = 10/20 = 1/2
So the answer is 1/2.

Answer: By SSS, ΔSUR ≅ ΔTVR.
Step-by-step explanation:
This might be a longer method, but still here you go.
Given, ΔSTU ≅ ΔTSV
By CPCT, we have the following.
∠TUS / ∠RUS = ∠SVT / ∠RVT ---- 1
SU = TV ---- 2
SV = TU ---- 3
∠STU / ∠STR = ∠TSV / ∠TSR
Now, in the triangle TRS,
TR = SR ( ∠TSR = ∠STR) ---- 4
SV= TU
SV - SR = TU - TR (SR= TR)
UR = VR ---- 5
Now, we can use SSS in the triangles ΔSUR and ΔTVR
SU = TV (2)
SR = TR (4)
UR = VR (5)
Therefore, by SSS, ΔSUR ≅ ΔTVR.

Answer: Nicole Kicked the ball Father by 22 feet than Tyrell.
Which girl's ball traveled the furthest, and by how far?The force of gravity caused the soccer ball to return to the girl.
By means of gravity, a planet or other body pulls items toward its center.
It is, in ideal circumstances, abiding by Newton's third law of gravitation and force.
Each action has a corresponding and opposing reaction.
So, when a boy kicks a ball and it comes back, that signifies he is abiding by the law.
Nicole kicked the ball 57 feet
Tyrel kicked the ball 35 feet
Nicole Kicked the ball Father by = 22feet
This is gotten by subtracting the distance Nicole kicked from that of Tyrel
=57 feet - 35feet = 22feet

Using rectangles whose height is given by the value of the function at the midpoint of the rectangle's base (the midpoint rule), estimate the area under the graph of the following function, using two and then four rectangles.
[tex]y=81-x^2[/tex] between [tex]x=-9[/tex] and [tex]x=9[/tex]
The estimates of the area under the curve using rectangles is given as follows:
Two rectangles: 729 units squared.Four rectangles: 911.25 units squared.How to approximate the area?The area under a curve is approximated using the definite integral of the function that defines the curve within it's bounds.
As it is specified that the area should be approximated using rectangles, a Left Riemann Sum will be used to approximate the area.
With two rectangles, the Delta value is obtained as follows:
[tex]\Delta_x = \frac{9 - (-9)}{2}[/tex]
[tex]\Delta_x = 9[/tex]
The values of x are obtained with the rule presented as follows:
[tex]x_i = a + \Delta_x(i - 1)[/tex]
With two rectangles, the values are given as follows:
-9 and -9 + 9 = 0.
The numeric values are given as follows:
x = -9: 81 - (-9)² = 0.x = 0: 81 - 0² = 81.The definite integral is given as follows:
[tex]\sum_{i = 1}^n = \Delta_xf(x_i)[/tex]
Hence the result is of:
9 x 81 = 729 units squared.
With four rectangles, the Delta value is given as follows:
[tex]\Delta_x = \frac{9 - (-9)}{4} = 4.5[/tex]
Hence the values of x are:
x = -9, x = -4.5, x = 0, x = 4.5.
The numeric values are:
x = -9: 81 - (-9)² = 0.x = -4.5: 81 - (-4.5)² = 60.75.x = 0: 81 - 0² = 81.x = 4: 81 - (-4.5)² = 60.75.Hence the result of the integral is given as follows:
4.5(60.75 + 81 + 60.75) = 911.25 units squared.

You can hire someone without experience for $13 per hour or someone with experience for $19 per hour. You believe the
experienced person increases the sales per customer by $3. Each person handles about 12 customers per hour. Should you hire the
experienced person?
a) Yes
b) No
Answer:
a) Yes
The experienced person costs more per hour, but also increases sales per customer. To determine if it is more cost-effective to hire the experienced person, you would need to calculate the net gain or loss from hiring them.
You can do this by multiplying the increase in sales per customer by the number of customers per hour, and comparing that to the difference in hourly wages.
(12 customers/hour * $3/customer) - ($19/hour - $13/hour) = $36/hour - $6/hour = $30/hour
Since the net gain is positive, it is more cost-effective to hire the experienced person.

Find the distance between the two points rounding to the nearest tenth (if necessary)
(3,2) and (6,0)
Answer:
The distance between two points in the coordinate plane can be found using the distance formula, which is:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
In this case, the two points are (3,2) and (6,0), so we can plug in the values to get:
distance = √((6 - 3)^2 + (0 - 2)^2)
distance = √((3)^2 + (-2)^2)
distance = √(9 + 4)
distance = √13
So the distance between the two points (3,2) and (6,0) is approximately 3.61 units.

The distribution of hourly rates of registered nurses in a large city has mean $31 and standard deviation $5.
a) What is the distribution of the sample mean based on a random sample of 100 registered nurses in the city?
b) Find the probability that the average hourly rate of the 100 nurse sample exceeds $31.50.
a) The distribution of sample means of 100 registered nurses in the city is approximately normal, with mean $31 and standard deviation of $0.5.
b) The probability that the average hourly rate of the 100 nurse sample exceeds $31.50 is of: 0.1587 = 15.87%.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n is approximately normal and has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The parameters for this problem are given as follows:
[tex]\mu = 31, \sigma = 5, n = 100, s = \frac{5}{\sqrt{100}} = 0.5[/tex]
The probability that the average hourly rate of the 100 nurse sample exceeds $31.50 is one subtracted by the p-value of Z when X = 31.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (31.5 - 31)/0.5
Z = 1
Z = 1 has a p-value of 0.8413.
1 - 0.8413 = 0.1587 = 15.87%.

The correct option regarding the quotient of the two fractions is given as follows:
B. [tex]\frac{(4x^2 + 6)(x + 2)}{10x^2 + 15}[/tex], no values must be excluded.
How to divide two fractions?The division of two fractions is given by the multiplication of the first fraction by the inverse of the second fraction.
The first fraction for this problem is given as follows:
(4x² + 6)/(x - 2).
The second fraction for this problem is given as follows:
(10x² + 15)/(x² - 4).
Applying the subtraction of perfect squares, we have that:
x² - 4 = (x + 2)(x - 2).
Then the division of the two fractions is given as follows:
(4x² + 6)/(x - 2) x [(x + 2)(x - 2)/(10x² + 15)]
Simplifying the x - 2 terms, we have that:
[tex]\frac{(4x^2 + 6)(x + 2)}{10x^2 + 15}[/tex]
No values must be excluded, as the denominator would be never zero, as:
10x² + 15 = 0
10x² = -15.
x² is always positive, hence 10x² will never be equals to -15.
