Answer:
-0.089
Step-by-step explanation:
Given that:
Males - Group 2:
Total number of males, n = 874
Number that said yes, = 396
P1 = 396 / 874 = 0.453
Females - Group 1 :
Total number of Females, n = 902
Number that said yes, = 489
P2 = 489 / 902 = 0.542
Point estimate of the difference in sample proportion:
P1 - P2
0.453 - 0.542
= −0.089

The ladder of a fire truck extends 41 ft. to the top of the
building. If the distance between the wall and the base of the
ladder is 9ft. How tall is the building?

Step-by-step explanation:
By the Pythagorean Theorem a^2+b^2=c^2 or the sum of the squared sides is equal to the hypotenuse squared.
41^2=9^2+h^2
h^2=41^2-9^2
h^2=1600

Niles scored 70, 74, 72, 71, 73, and 96 on his 6 Geography test. Calculate the mean and median.
Answer:
Mean=76
Median=72.5
Step-by-step explanation:
Mean= 70+71+72+73+74+96
456/6=76
Median = 70,71,72,73,74,96
72+73=145/2=72.5
Mean= 76
Median= 72.5
The first step is to rearrange the numbers
70, 71, 72, 73, 74, 96
1. mean= sum of terms/number of terms
= 70+71+72+73+74+96/6
= 456/6
= 76
2. Median can be described as the middle number, the median can be calculated as follows
= 72+73/2
= 145/2
= 72.5
Hence the mean is 76 and the median is 72.5

Answer:
(f o g)(x) = 4x^2 - 8
Step-by-step explanation:
(f o g)(x) = f(g(x))
f(x) = x^2 - 8
g(x) = 2x
f(g(x))
f(2x) = (2x)^2 - 8
= 4x^2 - 8
(f o g)(x) = 4x^2 - 8
In continuous type of series, for finding mean, which amongst the
following is considered as X variable value?
Select one:
O a lower limit of the interval
O b. upper limit of the interval
O c. mid point of the interval
O d. none of these
In the continuous type of series for determining the mean, the midpoint of the interval should be considered as the X variable value.
Continuous Series is the series where all types of class intervals with the frequency should be listed in the table form. Here all the class intervals do not contain a similar frequency.
For determining the mean, the direct method should be used in which the midpoint from X should be measured and the same should be relevant.
So, the following should not be relevant for determining the mean:
The lower limit and upper limit of the interval.Therefore In the continuous type of series for determining the mean, the midpoint of the interval should be considered as X variable value.

Solve for the variable indicated
-4x-8y=36 solve for x
Answer:
x = -2y - 9
Step-by-step explanation:
First isolate the variable by putting the x on a side by itself.
-4x=36+8y (8y becomes positive when it changes sides)
Then divide the entire equation by -4 to make the x stand alone.
x = -9 -2y
Some teachers prefer the variables at the beginning of the equations so it could also read
x = -2y - 9
Hello there!
Question:-
[tex]-4x-8y=36[/tex]
We need to find the value of x.
Solution:-
[tex]\sf \longmapsto-4x-8y=36[/tex]
Firstly, Add 8y to both sides :-
[tex]\sf \longmapsto \: - 4x - 8y+8y=36+8y[/tex]
On Simplification:-
As (-) and (+) equals to (-),It Will be 8y-8y.Answer would be 0.
[tex]\sf \longmapsto \: - 4x - 0 = 36 + 8y[/tex]
[tex]\sf \longmapsto \: - 4x = 8y + 36[/tex]
Then, Divide both sides by -4:-
[tex]\sf \longmapsto \: \dfrac{4x}{ - 4} = \dfrac{8y + 36}{ - 4} [/tex]
On Simplification:-
[tex]\sf \longmapsto \: x = - 2y - 9[/tex]
______________________________________
Henceforth the value of x is :-
[tex] \boxed{\tt \: x = - 2y - 9}[/tex]

Step-by-step explanation:
The quotient of a number and 4 translates to 4x because, "a number" in the expression is x, and it is being multiplied by 4, so you get 4x. six more than would mean adding 6. So the answer would be 4x+6. Thank you! Good Luck!

Answer:
y = 120
Step-by-step explanation:
y = 4x (corresponding angles)
y + 2x = 180
substitute the value of y into the second equation
4x + 2x = 180
6x = 180
x = 30
now that we have the value of x, plug it into either equation and solve for y
y = 4 (30)
y = 120

A Ferris wheel has a radius of 37 feet. The bottom of the Ferris wheel sits 0.6 feet above the ground. You board the Ferris wheel at the 6 o'clock position and rotate counter-clockwise.
Write a function f that determines your height above the ground (in feet) in terms of the number of radians you have swept out from the 6 o'clock position, a.
f(a)=
Write a function g, that determines your height above the ground (in feet) in terms of the number of feet you have traveled since you started rotating, s.
g(s)=
Answer:For the first one, it should be f(a)=37.8(1-cos(a))+.7. My dearest apologies because I do not know why. I just used context from the previous questions. I hope that helps..!
Step-by-step explanation:
The height of the given Ferris wheel can be described with the aid of a
sinusoidal function.
The height above the ground in terms of the angle turned, a, is
presented as follows;
[tex]\underline{f(a) = 37 \cdot sin \left (a - \dfrac{\pi}{2} \right) + 0.6}[/tex]The height above the ground in terms of the distance traveled, s, is
presented as follows;
[tex]\underline{g(s) = 37 \cdot sin \left (\dfrac{37}{s} - \dfrac{\pi}{2} \right) + 0.6}[/tex]Reason:
The general form of an equation of a Ferris wheel is presented as follows;
f(a) = A·sin(a + C) + D
Where, the amplitude, A = The radius = 37 ft.
D = The midline = Height above the ground + The amplitude
D = A + 0.6 = 37 + 0.6 = 37.6
The 6 O'clock is the lower most position, therefore, at the start, where, 'B·t + C' = 0, we have;
f(a) = A·sin(0 + C) + D
Therefore
f(a) = 37·sin(0 + C) + 37.6 = 0.6
f(a) = 37·sin(C) = 0.6 - 37.6 = -37
[tex]sin(C) = \dfrac{-37}{37} = -1[/tex]
C = sin⁻¹(-1) = [tex]-\dfrac{\pi}{2}[/tex]
The equation of Ferris wheel is presented as follows;
Which gives the equation of the height above the ground (in feet) in terms
of the number of radians, a, you have swept out from the 6 O'clock
position is given as follows; Ferris ;
[tex]\underline{f(a) = 37 \cdot sin \left (a - \dfrac{\pi}{2} \right) + 0.6}[/tex]Part 2
s = a·r = a·A
Therefore;
[tex]a = \dfrac{r}{s} = \dfrac{A}{s} = \dfrac{37}{s}[/tex]
Plugging the value of s into the above equation gives the function that
determines the height above the ground (in feet) in terms of the number of
feet traveled g(s) as follows;
[tex]\underline{g(s) = 37 \cdot sin \left (\dfrac{37}{s} - \dfrac{\pi}{2} \right) + 0.6}[/tex]Learn more here:

Liquid A and liquid B are mixed to make liquid C.
Liquid A has a density of 70 kg/m Liquid A has a mass of 1400 kg
Liquid B has a density of 280 kg/m Liquid B has a volume of 30 m
Work out the density of liquid C.
Answer:
Density is defined as:
Density = mass/volume.
We know that:
For liquid A:
Density = 70kg/m^3
Mass = 1400kg
Then the volume is:
Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3
For liquid B:
Density = 280 kg/m^3
Volume = 30m^3
We can find the mass of liquid B as:
mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg
We know that liquid C is a mixture of liquid A and B.
Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:
Mass of liquid C = 1400kg + 8400kg = 9800kg
The same happens for the volume, then:
Volume of liquid C = 30m^3 + 20m^3 = 50m^3
Then the density of liquid C is:
Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3
