The test statistic based on the probability illustrated is -3.22.
How to illustrate the probability?Based on the information, the test statistic will be:
= (0.4 - 0.5)/[✓0.5(1 - 0.5)/260]
= -3.22
The p value using the distribution table is 0.0012.
The conclusion is to reject the null hypothesis as there's sufficient evidence to warrant rejection.

Melanie purchases 6 basketballs and 2 volleyballs for $114. A volleyball cost her $3 less than a basketball. How much did each volleyball cost?
Answer:
a volleyball is $16.5
Step-by-step explanation:
6b+2v= 114
v=b-3
6b+2(b-3)= 114
6b + 2b - 6
8b - 6 = 114
8b = 108
b= 13.5
substitute b in
6(13.5) + 2v = 114
81 + 2v = 114
2v = 33
v= 16.5
3. Solve for x.
(x-2)(x+ 8) = 0
Answer:
x = 2, x = -8
Step-by-step explanation:
Since the equation equals 0, you know either (x-2) or (x+8) has to equal 0.
This means x = 2, and x = -8

Answer: 7x+28=119
x=13
Step-by-step explanation:
Answer:
119= 7x + 28
x=13
Step-by-step explanation:
This problem requires an equation. y= mx+ b, where y is your total, mx is your slope, and b is your y intercept. Your total is 119, your yearly fee is 28 ( which is b since it only happens ones), and 7 is x (since x represents each time) So 119=7x+28. Now to solve this we would subtract 28 from both sides and then divide that number by 7. So 119-28 is 91. 91/7 is 13. He used the racketball court 13 times. You can plug 13 to make sure.
119= 7(13) + 28.

An airline company does not charge an extra fee if the weight of a passenger's luggage is less than 55 pounds.
Part A
On the number line, represent the values when the airline company does not charge an extra fee.
Part B
Create an inequality that represents this situation. Let p represent the weight of a passenger's luggage
Answer:
Let's solve first the part B.
We know that the company does not charge an extra fee is the luggage is less than 55 pounds.
Then if p represents the weight of the passenger's luggage, we need to have:
p is smaller than 55 lb
We also can write this as:
p < 55lb
where the symbol "<"
means that the left side is strictly smaller than the right side.
If we want to be more precise in the notation, we also should have a lower limit.
0lb < p < 55lb
Where the lower limit is because the weight of the luggage can not be zero or smaller than zero.
This is the inequality we wanted.
Now, how we represent this on a number line?
when we have:
x > a
We represent this with a open circle at x = a (this means that x = a is not a solution) and we draw an arrow to the right of a.
and for:
x < a
we represent this with an open circle at a, and we draw an arrow to the left of a.
And if we have:
a < x < b
we draw an open circle at x = a and another at x = b, and all the points between these circles will be solutions.
You can see the graph of the inequality below.
Part A)
(where the point of the arrow should not be there, and both circles should be white)

In triangle ABC , M and N are midpoints of sides. If MN = 2x + 5 and BC = x2 − 2, find the possible lengths for MN.
A. 17
B. 6 and 2
C. 1 and 17
D. 2 and 34
Answer:
A.17
Step-by-step explanation:
The possible lengths for MN are 17 and 1, so the correct answer is C. 1 and 17
How to get the lengthsSince MN = 2x + 5 and BC = x^2 − 2, we can write the equation
[tex]2x + 5 = (1/2)(x^2 - 2)[/tex]
Solving for x, we get:
[tex]2x + 5 = (1/2)(x^2 - 2)[/tex]
[tex]4x + 10 = x^2 - 2[/tex]
0 = [tex]x^2- 4x-12[/tex]
0 = (x - 6)(x + 2)
This equation has two solutions: x = 6 and x = -2.
Substituting these values into the expression for MN, we find that MN can have two possible lengths:
MN = 2(6) + 5 = 17 or
MN = 2(-2) + 5 = 1.
Therefore, the possible lengths for MN are 17 and 1, so the correct answer is 17 and 1.
