H1: u <7
This test is left tailed that is 1 tailed.
Significance alpha = 0.05
Degrees of freedom = 50-1 = 49
Using t distribution table at alpha = 0.05 and df = 49
Critical value = -1.677
We find t test
= 6.8 - 7/(0.9/√50)
= -0.2/0.9/√50
= -1.5713
-1.5713 is greater than -1.6777 so we fail to reject the null hypothesis
Using excel p value = 0.061 which is greater than 0.05
So we conclude that college students sleep less than typical american

Required
Select 2 equivalent expressions
The equivalent expressions are (a) and (c) and the proof is as follows
(a)
[tex](8x^6) * (xy^2)^3[/tex]
Open brackets
[tex](8x^6) * (xy^2)^3 = 8x^6 * x^{1*3}y^{2*3}[/tex]

Apply law of indices
[tex](8x^6) * (xy^2)^3 = 8x^{6+3}y^6[/tex]
[tex](8x^6) * (xy^2)^3 = 8x^9y^6[/tex]

Answer:
[tex]\boxed {\boxed {\sf D. \ 64x^{12}y^6z^2}}[/tex]
Step-by-step explanation:
This is an example of a power to a power. The exponents inside the parentheses are being raised to another power outside the parentheses. We multiply the exponents and take the coefficients (number in front of the variables) to the power.
[tex](8x^6y^3z)^2[/tex]
Remember that a variable without an exponent has an implied exponent of 1.
[tex]8^2x^{6*2}y^{3*2}z^{1*2}[/tex]
Solve the coefficient's exponent.
8²= 8*8= 64[tex]64x^{6*2}y^{3*2}z^{1*2}[/tex]
Multiply the exponents.
[tex]64x^{12}y^{6}z^{2}[/tex]
So, the expression given is equal to Choice D: 64x¹²y⁶z²

Triangle Congruency
Answer
where is the pdf?
Step-by-step explanation:
Simplify: 14ba2+21ab2−ab2.
The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².
What is simplification?In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.
The expression is given in the question, as follows:
14ba²+21ab²−ab²
When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².
Thus, the given expression can be simplified to 14ba²+20ab².

An isosceles triangle has two sides that are twice as long as the third side. If the perimeter is 60, what is the length of each side of the triangle?
Which graph represents the solution say to the system of equations
Answer:
Step-by-step explanation:
System of equations has been given as,
y = [tex]-\frac{1}{2}x+3[/tex] -------(1)
and y = [tex]\frac{1}{2}x-1[/tex] -------(2)
Slope-intercept form of the equation of a line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
By comparing this equation with the given lines,
y-intercepts of the given equations are 3 and -1
For solution of the systems,
[tex]-\frac{1}{2}x+3=\frac{1}{2}x-1[/tex]
[tex]\frac{1}{2}x+\frac{1}{2}x=3+1[/tex]
x = 4
From equation (2),
y = [tex]\frac{1}{2}(4)-1[/tex]
y = 1
Point of intersection of these lines is (4, 1).
Therefore, 4th graph (Extreme last from the left) will be the answer.
Find the sum of the measures of the exterior angles of a convex 39-gon
The sum of the measures of the exterior angles of a convex 39-gon will be 360°.
What is a polygon?The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
The measure of the exterior angle of the 39-gon will be given as,
Exterior angle = 360° / 39
Then the sum of the measures of the exterior angles of a convex 39-gon will be given as,
⇒ 39 x (360° / 39)
⇒ 360°
The sum of the measures of the exterior angles of a convex 39-gon will be 360°.

A 4-story building is 29 feet tall. Between which two whole numbers does the height of each story lie?
Answer:
7 & 8
Step-by-step explanation:
29÷4=7.25
7<7•25<8
The inequality of the height of the building is given by 7 < A < 8 , where A is the height of the building = 7.25 feet
Given data ,
A 4-story building is 29 feet tall
So , the height of the each story is given by the equation ,
To determine the height of each story in a 4-story building, we divide the total height of the building (29 feet) by the number of stories (4).
A = 29/4
On simplifying the equation , we get
29 feet ÷ 4 stories = 7.25 feet per story
Now , the inequality representing the height of the building between the whole numbers is given by
7.25 lies between 7 and 8
So , the inequality is 7 < A < 8
Hence , the height of each story in the 4-story building lies between 7 feet and 8 feet
