Coach Elyson claims that 90% of her volleyball serves are good serves. The captain of the team thinks Coach Elyson has a lower rate of good serves. To test this, 50 of the coach’s serves are randomly selected and 41 of them are good. To determine if these data provide convincing evidence that the proportion of Coach Elyson’s serves that are good is less than 90%, 100 trials of a simulation are conducted. The team captain’s hypotheses are: H0: p = 90% and Ha: p < 90%, where p = the true proportion of Coach Elyson’s serves that are good. Based on the results of the simulation, what is an estimate of the P-value of the test?
A dotplot. A number line labeled simulated sample proportion of good serves goes from 80 to 98 percent. 80, 2; 84, 13; 86, 11; 88, 12; 90, 23; 92, 12; 94, 14; 96, 10; 98, 3.

Each face of a small cube has a surface area of 0.25 square meters. A larger cube has edges that are six times as long as the edges of the small cube. What is the volume of the larger cube?
Answer:
27 m^3
Step-by-step explanation:
Answer:
The volume of the larger cube is 27 cubic meter.
Step-by-step explanation:
Given : Each face of a small cube has a surface area of 0.25 square meters. A larger cube has edges that are six times as long as the edges of the small cube.
To find : What is the volume of the larger cube?
Solution :
Each face of a small cube has a surface area of 0.25 square meters.
The surface area of each face of cube is SA=a^2
0.25=a^2
a=sqrt (0.25)
a=0.5
A larger cube has edges that are six times as long as the edges of the small cube.
i.e. A=6a
The edge of larger cube is A=6(0.5)=3
The volume of larger cube is V=A^3
V=(3)^3
V=27 m^3
Therefore, the volume of the larger cube is 27 cubic meter.
Verify that your point from Question 2 is a solution to 2x-y=-12x−y=−1 AND is also a solution to y=5x-5y=5x−5. What does it mean if your point is a solution to both?
(The point is (2,5))
Answer:
(a) Verified
(b) They are simultaneous equations
Step-by-step explanation:
Given
[tex]2x - y = -1[/tex]
[tex]y =5x - 5[/tex]
Required
Verify that: [tex](x,y) = (2,5)[/tex] is a solution
We have:
[tex]2x - y = -1[/tex]
Substitute: [tex](x,y) = (2,5)[/tex]
[tex]2 * 2 - 5 = -1[/tex]
Evaluate all products
[tex]4 - 5 = -1[/tex]
Subtract:
[tex]-1 = -1[/tex]
Because both sides of the equation are equal, then the point is a solution
Also: [tex]y =5x - 5[/tex]
Substitute: [tex](x,y) = (2,5)[/tex]
[tex]5 = 5 * 2 - 5[/tex]
Evaluate all products
[tex]5 = 10 - 5[/tex]
Subtract:
[tex]5 = 5[/tex]
Because both sides of the equation are equal, then the point is a solution
Because the given point is a solution to both equations, then they are simultaneous equation

-12=-8z+12 please need help
Answer:
z=3
Step-by-step explanation:
-12=-8z+12
-12-12=-8z
-24=-8z
-24/-8=z
z=24/8
3=z
z=3
Answer and Step-by-step explanation:
To solve for z, we have to get everything away from z.
First, subtract 12 from both sides of the equation.
-24 = 8z
Now, divide each side by 8.
-3 = z
z is equal to -3 (negative three).

The inequality is solved and the solution is x > 8/3
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
18 - 3x < 10
Adding 3x on both sides , we get
3x + 10 > 18
Subtracting 10 on both sides , we get
3x > 8
Divide by 3 on both sides , we get
x > 8/3
Hence , the inequality is x > 8/3

One number is 4 less than a second number. Twice the second number is 13 less than 5 times the first. Find the two numbers.
Answer:
7 , 11
Step-by-step explanation:
Let the second number be 'x'
the first number = x - 4
Twice the second number : 2*x = 2x
5times first = 5*(x -4) = 5*x - 5*4 = 5x - 20
13 less than 5 times the first = 5x - 20 - 13 = 5x - 33
5x - 33 = 2x
Add 33 to both sides
5x - 33 + 33 = 2x +33
5x = 2x + 33
Subtract '2x'from both sides
5x - 2x = 2x - 2x + 33
3x = 33
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{33}{3}[/tex]
x = 11
