Answer:
There is significant evidence that treatment will create effect on the subject. Hence We reject H0
Step-by-step explanation:
H0 : μ = 37
H1 : μ ≠ 37
μ = 37 ; σ = 7 ; sample size, x = 51 ; sample size, n = 1
Decision region :
If P value < α ;
Reject H0
Using the Z test statistic :
Zstatistic = (x - μ) ÷ (σ / √n)
Zstatistic = (51 - 37) ÷ (7 / 1)
Zstatistic = 14 ÷ 7
Zstatistic = 2
Obtaining p value from Zstatistic using the p value calculator ;
Zscore = 2 ; 2-tailed test, significance level = 0.05
P value = 0.0455
Zcritical at α = 0.05 for a 2 - tailed test = 1.96
0.0455 < 0.05
There is significant evidence that treatment will create effect on the subject. Hence We reject H0

Would the three squares below join together to make a right triangle? Why or why not? picture shows squares
Answer:
Yes.
The first has an area of 9, so each side is three.
The second has an area of 16, so each side is four.
Each side of the third square is given as 5.
So the triangle has sides of 3, 4, and 5.
3²+4²=5²
9+16=25
25=25 It works given the Pythagorean theorem.
Step-by-step explanation:
Yes.
The first has an area of 9, so each side is three.
The second has an area of 16, so each side is four.
Each side of the third square is given as 5.
So the triangle has sides of 3, 4, and 5.
3²+4²=5²
9+16=25
25=25 It works given the Pythagorean theorem.
Which variable expression represents the phrase "the quotient of 5 times a number and 2"
Answer:
5n/2
Step by Step Explanation:
Well, 5 times a number (the number is a variable so you just put it next to the 5) and 2 so you are dividing by 2 and the fraction bar is the same as division so 5n/2

make a graph on f(x)=−3/2(x+1)(x−5)
Answer:
explanation below
Step-by-step explanation:
f(x) = −3/2(x+1)(x−5) = -3/2 (x²-4x-5) = -3/2 (x²-4x+4-9) = -3/2 ((x-2)² - 9)
f(x) = -3/2 (x-2)² + (-3/2)*(-9) = -3/2 (x-2)² + 13.5
There are points to be referenced for the graph:
vertex (2 , 13.5) axis of symmetry: x = 2
roots: (-1 , 0) (5 , 0)
-3/2 : curve downward

Find the first 3 terms of arithmetic sequence if t5=-154 and t9=-274. find t1, t2, t3
Answer: t1 = -34; t2 = -64; t3 = -94
d is the distance between numbers (d > 0)
we have:
t5 = t1 + 4d = -154
t9 = t1 + 8d = -274
we have the equations:
t1 + 4d = -154
t1 + 8d = -274
<=> t1 = -34
d = -30
with t1 = -34 and = -30 => t2 = -34 - 30 = -64
t3 = -64 - 30 = -94

Please help me with this question please help me I beg you
Step-by-step explanation:
Given
f(x) = 5 / 2x - 1
f^-1( x) = ?
Let
y = f(x)
y = 5/2x - 1
Interchanging the roles of x and y we get
x = 5/2y - 1
2y - 1 = 5/x
2y = 5/x - 1
y = (5/x - 1)/ 2
f^-1(x) = ( 5/x - 1) / 2

Is y=-3x+6 linear or nonlinear
Answer:
373737373737373383847484
This equation is in the form y = mx + b and when a function
is written in this form, we know that it's a linear function.
Another way to tell that it's a linear function is
that the variable is raised to the first power.
Enter the value for the variable x in the equation:

what is the slope of the line that passes through the point -1 negative 10 + negative one negative to write your answer in simplest form what is the answer
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Point\ 1: -1, -10[/tex] --- [tex](x_1,y_1)[/tex]
The second point is incomplete. So, I will make assumptions
[tex]Point\ 2:1, -4[/tex] -- [tex](x_2,y_2)[/tex]
Required
Calculate the slope (m)
This is calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-4 - (-10)}{1 - (-1)}[/tex]
[tex]m = \frac{-4 +10}{1 +1}[/tex]
[tex]m = \frac{6}{2}[/tex]
[tex]m =3[/tex]
Using the assumed values, the slope is 3
Use the circle below to find the following measures.
Arc QT = and
Answer:
m(arc QT) = 142°
m(arc STR) = 314°
Step-by-step explanation:
"Measure of intercepted arc is double of the inscribed angle"
From the picture attached,
Measure of inscribed angle QST = 71°
Therefore, measure of arc QT = 2 × Measure of angle QST
= 2(71°)
= 142°
Since, m(arc SR) + m(arc STR) = 360°
46° + m(arc STR) = 360°
m(arc STR) = 360° - 46°
= 314°

The answer for number 1 is 1.72. The answer for number 2 is 4.83.
So for number one, the first thing you need to do is determine how many sides are on the first shape. Since it is a pentagon, and one pentagon has 5 sides, then you use the following formula to determine the volume of a[tex]V = \frac {1}{4} \times \sqrt{5 \times (5 +2 \times \sqrt {5})} \times (10)^{2} \times 10[/tex] pentagon: [tex]\alpha = \frac{1}{4} \times \sqrt[]{5(5+2 \sqrt[]{5}) \alpha ^{2} }[/tex] And in this case, the area would be 1.72, because if you insert the side lengths, the equation would look like this: [tex]V = \frac {1}{4} \times \sqrt{5 \times (5 +2 \times \sqrt {5})} \times (10)^{2} \times 10[/tex] , which if you solve this equation, then you will end up with the answer of 1.72.
For number two, the first thing you need to do is determine how many sides are on the second shape. Since it is an octagon, and the prefix oct means 8, the number of sides on the shape is 8. If the perimeter is 64, and there are 8 sides, you can divide 64 by 8 to get 8. The equation to solve for the area should look like this: [tex]V = 2(1 + \sqrt{2}) \times s^{2} \times h[/tex]. Now all you need to do is insert the side lengths to the proper places. It should then look like this: [tex]V = 2(1 + \sqrt{2}) \times 8^{2} \times 8[/tex], after you solve the equation, you should end up with 4.83.
