The group of 23 bully-victims scored an average of 40.1 with a sample standard deviation of 10 on the depression scale. The group of 28 bystanders scored an average of 46.8 with a sample standard deviation of 11 on the same scale. You do not have any presupposed assumptions about whether bully-victims or bystanders will be more depressed, so you formulate the null and alternative hypotheses as:
Answer:
Null Hypothesis = Depression levels among two groups equal, Alternate Hypothesis = Depression levels among two groups unequal.
Step-by-step explanation:
Null Hypothesis is the neutral hypothesis, of no difference.
Null Hypothesis in this case is, mean depression level among victims = mean depression level among bystanders.
Alternate Hypothesis in this case is, mean depression level among victims ≠ mean depression level among bystanders.

Connor’s temperature was 0.7 degrees higher last night than it was this morning. His temperature this morning was 101.2 degrees. What was his temperature last night?
Answer:
101.9 degrees
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
Let's define what we have:
Conner's morning temperature: 101.2 degrees
Conner's last night temperature: morning temperature + 0.7 degrees
We know that Conner's last night temperature is addition because it was higher (key word) than the morning temperature.
Therefore, we simply add the values together to get our answer:
101.2 + 0.7 = 101.9 degrees

if a person walks 3/4 of a mile in each 2/3 hour how far does he walk in one hour
Answer:
I believe it's 9/8 miles per hour

If an exterior angle measure of a regular polygon is 60°, how many sides does the polygon have? What is the measure of each interior angle?
9514 1404 393
Answer:
6 sides120°Step-by-step explanation:
The sum of the measures of the exterior angles of a convex polygon is always 360°. If each is 60°, there are 360°/60° = 6 of them.
There are 6 sides.
The adjacent interior angle is the supplement of the exterior angle, so is ...
180° -60° = 120°.
Each interior angle measures 120°.
Why is this not in quadratic form?
x^6+ 5x^4 + 6
Answer and Step-by-step explanation:
Quadratic form has only the exponent of 2 and 1 in it. An example of it is as shown:
3x^2 + 4x - 12
Your expression isn't a quadratic since it has a 6 as the highest exponent, but it is a trinomial (an expression that has 3 terms).

A perfume manufacturer puts 16 fluid ounces in each bottle. How many gallons will fill 96 bottles?
Answer:
12,228 ounces
Step-by-step explanation:
There are 128 ounces in a gallon. So multiply 128 ounces by the number of gallons.
128 x 96 = 12,228
96 bottles of perfume will fill 12 gallons.
Given that a perfume manufacturer puts 16 fluid ounces in each bottle.
We need to find how many gallons will fill 96 bottles,
To find the total number of gallons required to fill 96 bottles, we need to calculate the total volume in fluid ounces and then convert it to gallons.
Given that each bottle contains 16 fluid ounces, the total volume in fluid ounces for 96 bottles can be calculated as:
Total fluid ounces = 16 fluid ounces/bottle x 96 bottles
Total fluid ounces = 1,536 fluid ounces
To convert the total volume from fluid ounces to gallons, we use the conversion factor:
1 gallon = 128 fluid ounces
Therefore, the total volume in gallons is:
Total gallons = Total fluid ounces / 128 fluid ounces/gallon
Total gallons = 1,536 fluid ounces / 128 fluid ounces/gallon
Total gallons = 12 gallons
So, 96 bottles will fill 12 gallons.

3x-4y=-2
3y-2x=1
Answer:
y = -1, x = -2
Step-by-step explanation:
First, multiply the top equation by 2 to make 3x become 6x:
6x - 8y = -4
Second, multiply the bottom equation by 3 to make -2x become -6x:
9y - 6x = 3
Add the two equations together, and you get:
y = -1
Plug in y as -1 into the first or second equation:
3x - 4(-1) = -2
OR
3(-1) - 2x = 1
x = -2
You bought some new fish and need the tank ready. You fill the tank with water and start running the filter system.You check the temperature of the water after 2 hours and notice the water is 78 degrees Fahrenheit. You need the temperature to be at 72 degrees Fahrenheit. after three additional hours and the water temperature is at so, you add the fish. What was the temperature when you first filled the tank?
Answer:
82 degrees
Step-by-step explanation:
It took 3 hours for it to go from 78 to 72.
Which is a rate of -2 degrees per hour
We want to know what the temperature was two hours before it was 78 degrees so we'd do 78 - (-2) which is 82
A radioactive isotope is decaying at a rate of 15% every hour. Currently there are 150 grams of the substance. Write an equation that will represent the number of grams present after n hours. How much will be left one day from now?A radioactive isotope is decaying at a rate of 15% every hour. Currently there are 150 grams of the substance. Write an equation that will represent the number of grams present after n hours. How much will be left one day from now?
Answer:
The equation that will represent the number of grams present after n hours is [tex]A(n) = 150(0.85)^n[/tex]
3.035 grams will be left one day from now.
Step-by-step explanation:
Exponential equation for the amount of a substance:
The exponential equation for the amount of a substance is given by:
[tex]A(t) = A(0)(1-r)^t[/tex]
In which A(0) is the initial amount and r is the decay rate, as a decimal, and t is the time period.
A radioactive isotope is decaying at a rate of 15% every hour.
This means that [tex]r = 0.15[/tex]
Currently there are 150 grams of the substance.
This means that [tex]A(0) = 150[/tex]
Write an equation that will represent the number of grams present after n hours.
[tex]A(n) = A(0)(1-r)^n[/tex]
[tex]A(n) = 150(1-0.15)^n[/tex]
[tex]A(n) = 150(0.85)^n[/tex]
How much will be left one day from now?
One day is 24 hours, so this is A(24).
[tex]A(24) = 150(0.85)^{24} = 3.035[/tex]
3.035 grams will be left one day from now.

Answer:
Must understand distance and slope formula first:
slope y_2-y_1/x_2-x_1
distance d=√((x_2-x_1)²+(y_2-y_1)²)
(Just search up the formulas if this isn't clear)
Step-by-step explanation:
For #13 take two points and put them in the distance formula remember (#,#) the first # is 'x' the second # is the 'y' in a point.
then you could simply type all that in a calculator and a single number should pop up indicating one of the lines (doesn't matter the #) then do the same for the second points (cuz you used two already you have two left) If the number is same as the first two points it's a pallelagram. (I tested it out got 7.07...)
For the slope you're doing something similar to the distance formula, you're filling out two sets of points into the slope formula if they come out the same # it's parallel.
of Kayla has a bowl of beads that contalns 42 yellow beads, 28 green beads, 12 white beads, and 18 red beads. She randomly draws a bead from
the bowl.
The probability of Kayla not drawing yellow or a green bead is
%. The probability of Kayla drawing red or a green bead is
%.
Answer:
a) You have a 30% of not drawing yellow or green
b) You'd have a 46% of frawing a red or green bead
Step-by-step explanation:
Total beads: 42 + 28 + 12 + 18 = 100
Green beads + yellow beads = 28 + 42 = 70
100 - 70 = 30
30/100 = 0.3 or 30%
Red beads + green beads = 18 + 28 = 46
46/100 = 0.46 or 46%
Answer:
1. 30%
2.46%
Step-by-step explanation:
The probability of Kayla not drawing a yellow or a green bead is 30 %. The probability of Kayla drawing a red or a green bead is 46 %.
