SOMEONE PLEASE HELP ASAP! Normal distribution models what type of variable? A.discrete random variable B.random variable C.discrete continuous variable D.random continuous variable
A normal distribution has its center at the mean and its spread is determined by the standard deviation. For the standard normal distribution, its mean is 0 and standard deviation is 1. It is in the shape of a bell curve. Most of the values fall in or around 0, forming the peak around this area. As you move away from 0, the values are less frequent which explains the drop-off. The distribution is continuous as you can have any real number (decimal or whole). It's also random because of the nature of statistics.
find the value of x
Answer:
62○
Step-by-step explanation:
To find the angle all you have to do is subtract 118○ from 180○ to get 62○. Because 180○ is a straight line! :)
Answer:
X = 62
Step-by-step explanation
To start we make x go next to 118 so they make a supplementary angle. We add x and 118 to make 180.
118 + X = 180, OR 180 - 118 = x
X = 62

Which represents continuous data? A) The number of times you flip a coin B) The number of students in a classroom C) The number of chocolate candies in a box D) The price of fish per pound
Answer:
D) The price of fish per pound
Step-by-step explanation:
A continuous data is one which can take any value . it can have even value between any two consecutive number.
Example :
continuous data can have value between 4 and 5 like 4.5 4.001 and so on.
Discrete data is one which can be counted such as number of flowers, no of cars in parking.
it can take value such as 1,2, 12, 66 etc.
____________________________________________
Let go through the option
A) The number of times you flip a coin
We can count the number of times a coin is flipped .
Like 2 times, 3 times and hence it is discrete data and not a continuous one.
B) The number of students in a classroom
Student in a classroom can also be counted.
in a class there can be 12, 50, 66 etc students not 12.1 , 50.5 etc.
hence it is discrete data and not a continuous one.
C) The number of chocolate candies in a box
Again, chocolate number can be counted .
Number of chocolate can be 2, 4, 5 and not 2.1 , 4.6 etc and
hence it is discrete data and not a continuous one.
D>The price of fish per pound
Price of fist cannot be counted . Further, price of fish can be $2.5 , $ 4.555
hence it is a continuous data.
Based on above discussion
continuous data is represented by The price of fish per pound

Because they are vertical angles, AEG=FEB
You can see that FED+DEB=FEB
Therefore, 80+20=FEB=100
Since FEB=100 and FEB=AEG
AEG=100
Answer:
100°
Step-by-step explanation:
In this question, vertical angles are key. If you didn't know, vertical angles are basically opposites of each other. A pair of vertical angles are equal.
ACE = 20°
FED = 80°
FED and CEG are vertical angles (+the 20 from ACE), so your answer is 100°

In numb3rs, they use math to solve crimes. One of the ways they use Math is to reveal patterns. What is the pattern in this sequence? What would be the first and last numbers be? (6, 14, 30, 62, 126)
Step-by-step explanation:
I think the first number is 2
Then 2 x 2 = 4 so there is a difference of 4 number
Then in between 6 and 14 there is a difference of 8 so 4 x 2 = 8
Then 16 so 8 x 2 = 16
So after 126 the number is 254
A study was done by an online retail store to determine the rate at which users used its website. A graph of the data that was collected is shown: A line graph with Number of Months on the x axis and Number of Users, in thousands, on the y axis. The x axis has a scale from 0 to 36 with an increment of 4. The y axis has a scale of 0 to 60 with increments of 6. A straight line connecting 0, 0 and approximately 36, 54 is drawn. What can be interpreted from the range of this graph? The range represents the 54-month time period of the study. The range represents the 36-month time period of the study. The range represents the number of users each month for 36 months. The range represents the number of users each month for 54 months.PLEASE HELP IT URGENT
Answer:
The correct option is C.
C) The range represents the number of users each month for 36 months
Step-by-step explanation:
We have been given that:
x-axis ⇒ Number of Months
y-axis ⇒ Number of Users
x-axis values = 0 to 36
y-axis values = 0 to 60
We have a function which is represented by a straight line from (0,0) to (36,54).
We have to find the RANGE of the function.
Range of a function is a complete set of values of dependent variable y, for all possible values of independent variable x
As total number of months = 36
Range is the set of all values of y (Number of Users) for each month for a period of 36 months.
Hence, the correct option is C.
Answer:
c

n is an integer and -2
Write down the possible values of n,
from smallest to largest.
Answer:
Step-by-step explanation:
-2 < n+3 ≤ 4
Make two separate equations,
-2 < n+3
Subtract 3 from both sides,
-2-3 < n + 3 -3
-5 < n
So, value of n should be greater than (-5)
n +3 ≤ 4
Subtract 3 from both sides
n ≤ 1
So, n value should be less than or equal to 1
So, n value should be greater than -5 and less than or equal to 1
n= { -4, -3 , -2 , -1 ,0 ,1 }
Use the method of substitution to solve the system of equations. please show your work! y=534x y=74.80x+1,419 Thank you so much! If you could also solve it graphically that would be best but if not thats okay!
Answer:
( 3, 1650 ), Where x = 3, and y = 1650 -
Approximately
Step-by-step explanation:
Take a look at the procedure below;
[tex]y = 534x,\\y = 74.80x + 1,419\\\\y = 534x,\\y - 74.8x = 1,419\\\\( 534x ) - 74.8x = 1,419\\459.2x = 1,419\\x = ( About ) 3\\\\y = 534 * ( x ),\\y = 534 * ( 3.1 ),\\y = ( About ) 1650[/tex]
We first converted the second equation into standard form, by subtracting 74.8x on either side. Afterwards we substituted 534x in replacement of y in this second equation, and solved for x. Knowing the value of x, it was substituted back into the first equation to solve for the value of y. Hence, the resulting solution is ( 3, 1650 ) - approximately.

Do 5 A,B for 10 points.
Answer:
X = C - By over A which also is A ≠ 0
Y = C - Ax over B which is also B ≠ 0
Step-by-step explanation:
Solve for x
First subtract "By" from both sides:
Ax + By - By = C - By
Then simplify,
Ax = C - By
Divide both sides by A:
Ax / A = C/A - By/A ; A≠0
Then simplify:
X = C - By over A ; A ≠ 0.
-------------------------------------
Solve for y
First subtract "Ax" from both sides:
Ax - By - Ax = C - Ax
Simplify,
By - C = Ax
Then divide both sides by B:
By/B = C/B - Ax/B ; B ≠ 0
Simplify:
Y = C-Ax / B ; B ≠ 0.

Find the area of the polygon shown in the figure.
Answer:
16
Step-by-step explanation:
Triangle area = (1/2)*b*h
Base = b = 4
Height = h = 8
Area = (1/2) * 4 * 8 = 16
The area of the polygon shown in the figure is 16 unit square.
What is a polygon?A polygon is a closed figure made up of three or more line segments connected end to end.
Triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
The area of the triangle is defined as the product of half the base and the height of the triangle.
The area of the triangle = 1/2 x b x h
WE can see from the given figure;
The Base = b = 4
The Height = h = 8
The Area of figure = (1/2) * 4 * 8
The Area of figure = 16
Hence, the area of the polygon shown in the figure is 16 unit square.

If you diluted 300 mL of 8% benzocaine lotion to 5% how much could you produce
Answer:
you are diluting it 8/5 times, or 1.6 times.
You could make 230*1.6 ml of 5 percent lotion.
If you diluted 300 mL of 8% benzocaine lotion to 5%, you will be able to produce 480 ml of 5% lotion.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The amount of benzocaine in 300 ml solution is,
Amount = 0.08 × 300 = 24ml
Since after the dilution the amount of benzocaine will be the same, therefore, we can write,
0.05 of X ml = 24 ml
X = 24/0.05
X = 480 ml
Hence, If you diluted 300 mL of 8% benzocaine lotion to 5%, you will be able to produce 480 ml of 5% lotion.
