Answer:
CI 90 % = [ 0,05 ; 0,16 ]
Step-by-step explanation:
From sample we got
n = 110
x = 21
p = 21/110 = 0.19 then q = 1 - p q = 1 - 0.19 q = 0.81
To create a 90 % confidence Interval, the significance level α = 10 %
α = 0.1 α/2 = 0.05
t(c) for α/2 = 0.05 is from z-table z(c) = 1.64
CI 90 % = ( p ± z(c) * √(p*q)/n
CI 90 % = [ 0,11 ± 1.64 * √ (0.19*0.81)/110 ]
CI 90 % = [ 0.11 ± 1.64 * 0.037 ]
CI 90 % = [ 0.11 ± 0,06 ]
CI 90 % = [ 0,05 ; 0,16 ]

Step-by-step explanation:
the first option : 0.073< 0.73
Answer:
O 0.073 < 0.73
Step-by-step explanation:
Definition of greater then and less thenThe greater than and less than symbols indicate a difference between two values. The symbol for greater than is " > ", and the symbol for less than is " <",
The value, O 0.073 is lesser then 0.73

Lincoln technical college has 156 students they expect 700 guest for a special speaker the custodian has set up 1500 chairs how many more chairs are needed if everyone is do you have a seat
Answer: 56 seats
Step-by-step explanation:
Question should say 856 students not 156 students.
If there are 856 students and 700 guests, the total number of people coming for the event is:
= 856 + 700
= 1,556 people
There are 1,500 seats so the extra seats needed are:
=Number of people coming - Seats available
= 1,556 - 1,500
= 56 seats
If the question is indeed 156 students then there is no need for extra seats as the total number of people coming would be: 156 + 700 = 856. Seats would be surplus.

Answer:
D.
Step-by-step explanation:
The volume can be found by adding the volumes of a cylinder (the upper part of the figure) and a cone (the lower part of the figure).
Volume of Cylinder: [tex]V=\pi r^2 h=\pi(3^2)(3)=27\pi\approx 84.823 \text{ cubic feet}[/tex]
Volume of Cone: The height of the cone is 3 feet (the whole figure is 6 feet tall and the cylinder uses up 3 feet of that -- 6 - 3 = 3).
[tex]V=\frac{1}{3}\pi r^2 h=\frac{1}{3}\pi(3^2)(3)=9\pi\approx 28.274[/tex]
The total volume is 84.823 + 28.274, about 113.1 cubic feet

so red is 4 times more often than blue, and blue is 2 times more often than green and green is as often as white so
so red would be the most oftenblue would be second most oftengreen and white are tied for thirdlets say it landed on red 16 timesif we do the math of 16/2 we get 8it landed on blue 8 timeshalve that again which is 4it landed on green 4 times and blue 4 timeswhich means out of 32 rolls we got red 16 times, blue 8 times, and green 4 times ad white 4 timesHope this helps i couldent really make a bar graph or a table chart but hope u can add this to a graph that u make

Solve for a side in right triangles
I don’t know how to do this so please someone teach me how to do this?? I need help here!
Answer:
2.33
Step-by-step explanation:
imagine a circle. its center is A, and it goes through B, so its radius is AB.
then it is important to know that the sum of all the angles in a triangle is 180 degrees.
one angle (at C) is 90. the angle at B is 25. so, the angle at A is 180 - 90 - 25 = 65 degrees.
more back to our circle.
in this circle the line CB is the sine of the angle at A multiplied by the radius.
and AC is the cosine of the angle at A multiplied by the radius.
we can ignore the orientation + and - of these functions, as we are only interested in the absolute length (and we can mirror the triangle, and all the angles and side lengths still stay the same).
=> CB = sin(A)×AB
AC = cos(A)×AB
=> 5 = sin(65)×AB
=> AB = 5 / sin(65)
=> AC = cos(65)×5/sin(65) = 5 × (cos(65)/sin(65)) =
= 5 × cot(65) = 2.33

Visualizing having one whole pizza.
Mark it into two sections. Each sections the same amount of pizza.
1/3 of 1/2 means take one of the sections called 1/2 of the pizza and mark it into three equal sections.
The other section called 1/2 can also be marked into three equal sections.
That will produce 6 smaller sections of the whole pizza.
Look at the one of the half of the pizza.
One of the three slices of 1/2 of the pizza is 1/3 of 1/2 of the pizza.
Look at the whole pizza. Isn’t the 1/3 of 1/2 = 1/6 of the whole pizza.
1/3(1/2) = 1/6
