Considering the given test, the p-value is of 0.1586, and the null hypothesis is not rejected at the 5% significance level.
What is the relation between the p-value and the decision?It depends it is less or greater than the critical value.
If it is less, the null hypothesis is rejected.If it is more, the null hypothesis is not rejected.In this problem, we use a t-distribution calculator, with t = 1.45, 27 df and a two-tailed test, as we are testing if the mean is different of a value. Doing it, the p-value is of 0.1586.
Since it is greater than 0.05, the null hypothesis is not rejected at the 5% significance level.

Prism M is a dilation of Prism N. The height of Prism M is 4 3/4 ft, and the volume of Prism M is 68 2/5 ft³. The height of Prism N is 2 3/8 ft. What is the volume of Prism N?Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
8 11/20 ft³
Step-by-step explanation:
For dilated figures, the ratio of volumes is the cube of the ratio of corresponding linear dimensions.
Vn/Vm = (Hn/Hm)³
Vn = Vm(Hn/Hm)³ = (68 2/5 ft³)((2 3/8 ft)/(4 3/4 ft))³
Vn = (342/5 ft³)((19/8)/(19/4))³ = (342/5 ft³)(1/2)³ = 342/40 ft³
Vn = 8 11/20 ft³
The volume of Prism N is 8 11/20 ft³.
Answer:
The answer is 8 11/20.
Tiana bought 3 video games that each cost
the same amount. The tax on each video
game was $1.29. She paid a total of $68.37
after tax. What was the price of each video
game, before tax?
a
well, we know she paid a total after tax of $68.37, we also know that each game had a tax of $1.29, so 3 games that'll be 3 * 1.29 = 3.87.
so if we take out the tax from 68.37, that'll be 68.37 - 3.87 = 65 bucks.
we know each game cost the same amount so 65 ÷ 3 ≈ 21.67 before tax.
Tiana bought 3 video games at a cost of $22.36 each, before tax. The total amount paid after tax was $68.37.
Given that,
Tiana bought 3 video games.
The cost of each video game was the same.
The tax on each video game was $1.29.
Tiana paid a total of $68.37 after tax.
To find the price of each video game before tax,
Start by subtracting the total tax from the total amount paid.
Tiana paid a total of $68.37 after tax and the tax on each video game was $1.29.
So, subtract the tax from the total amount to get the price before tax.
$68.37 - $1.29 = $67.08.
Since Tiana bought 3 video games,
Divide the total price before tax by 3 to find the price of each video game.
$67.08 ÷ 3 = $22.36.
Hence, the price of each video game before tax was $22.36.

(Simplify your answer.)
The geometric sequence can increase or decrease exponentially
The correct sum of the 4th and the 5th terms is 432
How to determine the correct sum?The given parameters are:
Initial value (a) = 4
Growth factor (r) = 3
The nth term of a geometric sequence is calculated as:
[tex]T_n = ar^{n-1}[/tex]
This gives
[tex]T_n = 4 * 3^{n-1}[/tex]
For the 4th term; we have:
[tex]T_4 = 4 * 3^{4-1}[/tex]
[tex]T_4 = 108[/tex]
For the 5th term, we have:
[tex]T_5 = 4 * 3^{5-1}[/tex]
[tex]T_5 = 324[/tex]

(0, 3); y = 4
(0, 4) ; y = 3
(0, 5) ; y = 4

What is the center and radius of the circle given by x2 + y2 - 10x - 12y + 24 = 0?
Answer:
centre (5, 6 ) , r = [tex]\sqrt{37}[/tex]
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r the radius
given
x² + y² - 10x - 12y + 24 = 0 ( collect x and y terms together and subtract 24 from both sides )
x² - 10x + y² - 12y = - 24
using the method of completing the square
add ( half the coefficient of the x / y terms)² to both sides
x² + 2(- 5)x + 25 + y² + 2(- 6)y + 36 = - 24 + 25 + 36
(x - 5)² + (y - 6)² = 37 ← in standard form
with centre (h, k ) = (5, 6 ) and r = [tex]\sqrt{37}[/tex]

Fifteen less than the square of a number is the same
as twice the number. Find the number.
Call the number : a
We have : [tex]a^{2} - 15 = 2a[/tex]
[tex]- > a^{2} - 2a = 15 - > a(a-2) = 15[/tex]
Now, we list all the numbers that can be multiplied to get 15 :
1 x 15 (and reverse)
3 x 5 (and reverse)
-1 x (-15) (reverse)
-3 x (-5) (a l s o r e v e r s e)
We substitute in :
If a = 1 -> a(a-2) = 1 x (-1) = -1 (not equal 15)
If a = 3 -> a(a-2) = 3 x 1 = 3 (not equal 15)
If a = -1 -> a(a-2) = -1 x (-3) = -3 (also not equal 15)
And if a = -3 -> a(a-2) = -3 x (-5) = 15 (satisfied)
So, the number is -3
Recheck : -3(squared) - 15 = 9 - 15 = -6
Twice of -3 = -6
[tex]========================================[/tex]
First of all, let the unknown number be z.
Then, "the square of z" means "z squared" which is the same as "z times z" or just z².
Now, "fifteen less than the square of z" means we subtract 15 from z²:
z²-15
Then, this equals twice the number, or 2 times z:
z²-15=2z

Answer:
$114.75
Step-by-step explanation:
You have to multiply the hours by the wage. Looking at the time that the worker was in during the morning, it was a total of 4 hours. Since the wage is $13.50/hr, we would multiply 13.50 by 4.
13.50 * 4 = 54.00
So, now we have to add together the total hours in the afternoon. If we count the time, we get 4 1/2 hours. So, now we multiply 13.50 by 4.5.
13.50 * 4.5 = 60.75
Now, to find the total pay for that day, we add both the morning and the afternoon pay together.
54.00 + 60.75 = 114.75
Therefore, the pay for this day is $114.75.

Volt Electronics sells a Y-Box game console for $207. The store markup on thr Y-Box is 38%. What was the wholesale price that the store paid for it?
The wholesale price that the store paid for the Y-Box game is $150.
What is the wholesale price?When the price of an item is marked up, it means that the price of the item was increased by a certain percentage. The good then becomes more expensive.
