The area of a sector of a circle with a radius measuring 15 cm is 235.62 cm^2 . What is the measure of the central angle, to the nearest degree that forms the sector?
Answer:
120°
Step-by-step explanation:
The area of a sector of a circle is given by:
[tex]A = \frac{\alpha }{360} * \pi r^2[/tex]
where α = central angle of sector in degrees
r = radius of circle.
The radius of the circle is 15 cm and the area of the sector is 235.62 cm^2. Therefore:
[tex]235.62 = \frac{\alpha }{360} * \pi * 15^2\\\\84823.2 = 706.86 * \alpha \\\\=> \alpha = 84823.2 / 706.86\\\\\alpha = 120^o[/tex]
The central angle of the sector is 120°

The heights of 82 roller coasters have a mean of 285.2 feet and a population standard deviation of 59.3 feet. Find the standardized tests statistics and the corresponding p-value when the claim is that roller coasters are more than 290 feet tall.
Answer:
0.7673
Step-by-step explanation:
We have the following:
The null and alternative hypothesis is,
H0: m = 290
Ha: m> 290
x = 285.2
m = 290
sd = 59.3
n = 82
is m the mean, sd the standard deviation and n the population size
Now we calculate the value of z like this:
z = (x - m) / sd / (n ^ (1/2))
z = (285.2 - 290) / 59.3 / (82 ^ (1/2))
z = -0.73
now
P (z> -0.73) = 1 - P (z <-0.73)
we look at the normal distribution table
P = 1 - 0.2327 = 0.7673
Therefore the value of p is equal to 0.7673

р
By considering bounds, work out the value of c for David's journey
to a suitable degree of accuracy.
You must show all your working and give a reason for your final answer.
Answer:
7
Step-by-step explanation:
LB of d = 186.5
UB of d = 187.5
LB of p = 27.5
UB of p = 28.5
186.5/28.5 = 6.54
187.5/27.5 = 8.81
The answer is 7 since both bounds round up to 7.
The value of c for the David journey is 7.
Calculation of the value of c:Since David drove a distance (d) of 187 km
So here the 3 significant figures should be
LB of d = 186.5
UB of d = 187.5
And,
LB of p = 27.5
UB of p = 28.5
Now the average should be
[tex]186.5\div 28.5[/tex] = 6.54
And,
[tex]187.5\div 27.5[/tex] = 8.81
So, The value of c for the David journey is 7.

What is an equation of the line that passes through the point (-1,2) and is parallel
to the line 3x + y = 3?
Answer:
y = - 3x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + y = 3 ( subtract 3x from both sides )
y = - 3x + 3 ← in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + c ← is the partial equation
To find c substitute (- 1, 2) into the partial equation
2 = 3 + c ⇒ c = 2 - 3 = - 1
y = - 3x - 1 ← equation of parallel line
The required equation of line which passes through points (-1, 2) and parallel to line 3x + y = 3 is 3x + y = -1
What is slope ?Slope is a notation that shows that a surface of which one end or side is at a higher level than another surface.
y - y₁ = m(x - x₁)
The given equation of line,
3x + y = 3,
The slope of the given line is -3,
The equation of the line that passes through points (-1, 2) and which is parallel to line 3x + y = 3
The slope of the required line will be same as slope of line 3x + y = 3.
The equation of line,
y - 2 = -3 (x - (-1))
y - 2 = -3 (x + 1)
y - 2 = -3x - 3
3x + y = -1

In a competition, 5 people can eat 20 steamed buns in 3 minutes 20 seconds.
Assuming that everyone consumes steamed buns at the same rate and that
the rate of consumption remains constant throughout the competition, find the
number of steamed buns 10 people can eat in 5 minutes.
Answer:
60 buns
Step-by-step explanation:
Assuming that the 5 people eat 20 steamed buns between them and not each, that is an average of 4 buns per person. this means that they eat one bun every 50 seconds. therefore, in 5 minutes one person can eat a total of 6 buns, meaning 10 people can eat 60.

determine The mean,median,mode, and range for each data set A. {2,2,7,9,10}
Answer:
Mean: 6, Median: 7, Mode: 2, Range: 8
Step-by-step explanation:
Mean:The mean is the average of the data set.
Add all the terms together:
[tex]2+2+7+9+10=\\4+7+9+10=\\11+9+10=\\20+10=\\\boxed{30}[/tex]
Divide the sums by the number of terms:
There are 5 terms in the data set.
[tex]30/5=6[/tex]
The mean is 6.
Median:The median is the middle value of the data set.
The data set given already has the numbers in ascending order.
Seven appears to be in the middle of the set.
{2,2,7,9,10}
The median is 7.
Mode:The mode is the number that appears the most in a data set.
The number two appears twice in the data set, and all other numbers (7, 9, and 10) appear once.
The mode is 2.
Range:The range is the difference between the largest data value in the set and the smallest data value in the set.
In the given set, 10 is the biggest and 2 is the smallest.
10 - 2 = 8
The range is 8.
Answer:
Step-by-step explanation:
Median:
2,2,7,9,10 - you have to always find the number on the middle. But if there is 2 numbers remaining, you have to add both of them and divide by 2. So the median here is: 7.
Mode:
2,2,7,9,10 - to find the mode you need to see what number repeats itself more. So the mode here is: 2.
Range:
2,2,7,9,10 - to find the range you need to put the numbers in order and subtract the smallest number from the highest number. So the range here is 10 - 2 = 8 .
Mean:
2,2,7,9,10 - to find the mean you need to add up all of the answers and then you need to divide that answer by how many numbers there are. So the mean here is: 2+2+7+9+10 = 30
30 divided by 5 (how many numbers there are) = 6

Mehmut is 4 times as old as his brother, but
next year he will be only 3 times as old. Find
Mehmut's age now?
ALICIA CONYERS
7:20 AM
Answer:
Mehmut is 8 years old.
Step-by-step explanation:
From the statement we can get the following information, let M be Mehmut's age and b brother's age:
M = 4 * b
M + 1 = 3 * (b + 1)
We replace the first equation in the second and we are left with:
4 * b + 1 = 3 * b + 3
4 * b - 3 * b = 3 - 1
b = 2
Now, we replace to calculate M:
M = 4 * b
M = 4 * 2
M = 8
Mehmut is 8 years old.
Un astrónomo coloco dos telescopios en diferentes puntos para observar un mismo evento. ¿A cuantos grados debe ajustar el campo visual del telescopio G para cubrir exactamente la misma area que el telescopio H?
A) 220 grados
B)110 grados
C)27.5 grados
D)55 grados
Necesito ayuda es urgente
Answer:
La respuesta correcta es;
D) 55 grados
Step-by-step explanation:
Por el cual el telescopio G está ubicado en el centro del círculo con radio = HG, tenemos por teorema de círculo;
El ángulo sostenido por un arco en el centro del círculo es dos veces el ángulo sostenido por el mismo arco en la circunferencia del círculo.
Por lo tanto, por el cual el ángulo subtendido por el arco que describe el campo de visión requerido de los telescopios se da como 110° para el telescopio H en el centro del círculo con radio HG, el ángulo que el arco del campo de visión subtiende en la circunferencia, en telescopio G = 110°/2 = 55°
Por lo tanto, el telescopio G tiene que ajustar el campo de visión en 55° para cubrir la misma área que el telescopio H.

Answer:
hope this helps you
We want to see if the two given lines are perpendicular or not.
We will see that yes, the lines are perpendicular.
First, let's define a general linear equation, it is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Two lines are perpendicular if the slope of one is equal to the inverse of the opposite of the slope of the other.
Also, if a line passes through two points (x₁, y₁) and (x₂, y₂) then the slope of the line is given as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So we can get the slopes of the two given lines, for line PQ we have:
[tex]a = \frac{3 - (-2)}{2 - (-3)} = 1[/tex]
For line RS we have:
[tex]a = \frac{-6 - (-1)}{15 - 10} = -1 = -(1/1)[/tex]
So you can see that the slope of line RS is equal to the inverse of the opposite of line PQ.
Then yes, the lines are perpendicular.

As an estimation we are told 5 miles is 8 km.
Convert 76 km to miles.
miles
Step-by-step explanation:
To help solve this question we will put it into a ratio:
MILES:KM
5 :8 This ratio shows that 5 miles equals 8km.
47.5 :76 We can put 76 on the km side because we are told that in
in the question. Lets find out how many times 8 was
multiplied to equal 76. 76 divided by 8=9.5 Because 8 was
multiplied by 9.5 we shall multiply 5km by 9.5 5x9.5=47.5
Therefore 76km is equal to 47.5miles.
If f(x)=7x+4x and g(x) =1/2x what is the value of (f/g)(5)
Answer:
(f/g)(5) = 22
Step-by-step explanation:
All we need to do is plug in 5 for x in both f(x) and g(x) then divide the result of f(x) and g(x) to find our final answer.
Step 1: Plug in 5 for x
f(x) = 7(5) + 4(5) = 55
g(x) = 1/2(5) = 2.5
Step 2: Divide f(x) by g(x)
f(5)/g(5) = 55/2.5 = 22

Standard deviation: s = StartRoot StartFraction (x 1 minus x overbar) squared + (x 2 minus x overbar) squared + ellipsis + (x n minus x overbar) squared Over n minus 1 EndFraction EndRoot.
A.) 0
B.) 4
C) 2
D.) 26.7
Answer: B) 4
Step-by-step explanation:
Using the formula
Standard deviation = √( (Σ ( x - π)²)/n)
To get the standard deviation, first we workout the Mean which is the simple average of the data set
n = 4
(13 + 17 + 9 + 21) / 4 = 60/4 = 15
Mean(x) = 15
Then (x-π)²
13 - 15 = (-2)² = 4
17 - 15 = (2)² = 4
9 - 15 = (-6)² = 36
21 - 15 = (6)² = 36
Σ ( x - π)² = (4 + 4 + 36 + 36) = 80
Standard deviation = √( (Σ ( x - π)²)/n
= √ (80/4)
=√20
= 4.47

A dealer bought 18 toy chairs at Rs.65 per chair he sold 12 of them at Rs.75 each and the remaining chairs at rs
60 each find his profit or loss percentage
Answer:
The dealer's profit percentage is 7.692%
Step-by-step explanation:
18 × 65 = 1170
He spent Rs.1170
12 × 75 = 900
60 × (18-12) = 360
900 + 360 = 1260
He got a profit of Rs.90.
1170 × (1 + x/100) = 1260
1 + x/100 = 14/13
x/100 = 1/13
x= 7.692307692
Answer:
7.7%
Step-by-step explanation:
spent= Rs. 65*18= Rs. 1170
earned= 12*Rs. 75+6*Rs. 60= Rs. 1260
profit= Rs. 1260- Rs. 1170= Rs. 90
profit %= 90/1170*100%= 7.7%
