A teacher has a large container filled with blue, red, and green beads. She wants her students to estimate the proportion of red beads. Each student shakes the container, selects 50 beads, counts the number of red beads, and returns the beads to the container. One student’s sample contained 19 red beads. The students are asked to construct a 95% confidence interval for the true proportion of red beads in the container. Are the conditions for inference met?
Yes, the conditions for inference are met.

Which equation matches the function shown in the graph?
A. y=2sin(1/2x)+1
B. y=3sin(2x)
C. y=2sin(2x)+1
D. y=3sin(1/2x)
Answer:
the answer is A. y=2sin(1/2x)+1
Step-by-step explanation:
I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph
The function that matches the graph is y= 2 sin(1/2x) +1.
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given:
let y = A sin ([tex]\omega[/tex]x + Ф)+ k
T= 4π, w= 2π/T = 1/2
Now, midline= 1/2( max + min)
=1/2(3-1)= 2/2
k=1
and, A= 3-1 = 2
So, y= 2 sin(1/2x + Ф) +1
as, Ф=0
So, y= 2 sin(1/2x) +1

What is the value of xin the solution to this system of equations?
y + 2x = -1
y =1/2x+4
Answer:
x = -2.
Step-by-step explanation:
y + 2x = -1
y = -2x - 1
y =1/2x+4
Subtracting the last 2 equations:
0 = -2x - 1/2x - 1 - 4
5 = - 5/2 x
x = 5 / -5/2
= 5 * 2 / -5 = -2.
Find the rate of change
Answer:
25
Step-by-step explanation:
rate of change =change of distance/ change of time
so if you look at the chart you can see these points: (2,50) and (6,150)
change of distance would be 150-50/ change of time which would be 6-2 which equals 100/4 which is 25, the rate of change.

Answer:
72°
Step-by-step explanation:
The full plate has a central angle of 360°.
7/35 × 360° = 72°
Answer:
72°
Step-by-step explanation:
In order to find the value of the central angle, you must first determine what percentage of the plate was broken.
Since 7 out of the total 35 inches of circumference were broken, you divide 7 by 35 ([tex]7/35[/tex]) and get 0.2, which means 20% of the plate is broken.
Now, knowing that a circle consists of 360°, you need to find 20% of 360.
Use the formula [tex]\frac{percent}{100} =\frac{part}{whole}[/tex] .
[tex]\frac{20}{100}=\frac{x}{360}[/tex]
360 x 20 = 7200
7200 ÷ 100 = 72
x = 72
So, the central angle is 72°.

Hello! 59.2 is our answer
This is because for all the triangles we do 5.4 x 4 = 21.6 then I divide by 2 cause thats the formula when doing triangles so I get 10.8 and sense all the triangle sides our the same I do 10.8 x 4 and get 43.2 then for the bottom side I just have to do 4 x 4 cause thats the formula and get 16 then I add these up so 43.2 + 16 = 59.2 and We get our answer 59.2 Hope this helps!

What is the surface area of a cube with a side length of 3/4 inch? Use the expression 6s 2, where is the side length of the cube
Answer: The surface area of the cube would be 3^3/4.
Step-by-step explanation:
A cube has 6 faces [ 6 surfaces ]. Each surface has a square shape.
The area of 1 surface= (side)^2= 3/4 · 3/4= 9/16 sqr.in.
Surface area of cube =9/16 · 1/6= 54/16.
divide both top and bottom (54 and 16) by 2. you should end up with 27/8.
27/8 = 3^3/4 sqr. in.

by sunrise. What is the expected temperature at sunrise?
Answer:
-17 degrees Celsius.
Step-by-step explanation:
If the temperature at midnight is -5, and it is supposed to drop 12 more by sunrise, the 12 degrees are subtracted from the initial temperature.
-5 - 12 = -17 degrees by sunrise.

If you vertically stretch the square root parent function, F(x)= square roor x, by 7 units, what is the equation of the new function?
Answer:
g(x) = 7√x
Step-by-step explanation:
Parent function: f(x) = √x
Parent function vertically stretched by a factor of 7: g(x) = 7√x
The equation of the new function is 7√x.
What is a scale factor?Scale factor is that it is a number that multiplies times a given quantity to produce a smaller or larger version of the original number. The ratio of any two corresponding lengths in two similar geometric figures.
For the given situation,
The equation is F(x) = √x
The parent function is vertically stretched by 7 units.
So, the new function is
⇒ [tex]7(\sqrt{x} )[/tex]
⇒ [tex]7\sqrt{x}[/tex]
Hence we can conclude that the equation of the new function is 7√x.

Write an inequality that describes the graph
Answer:
x<4
Step-by-step explanation:
The arrow is facing left, making it less than. Next, the open circle on 4 means that it does not include 4, therefore the inequality is x<4.
The inequality that represents this situation is - ∞ ≤ x < 4.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Assuming the number line is represented by x.
An open circle on the right-hand side of the line at 4 represents it is less than 4.
We can also observe that the line is going infinitely in the direction of negative infinity.
So, this situation can be represented by an inequality of the form
- ∞ ≤ x < 4.
