Look at Data Set A
1 3 3 2 4 0 4 3 3 5 2
Identify whether this will be normal distribution or skewed left or right? (Hint: find the five number summary and make a box plot)
O skewed left
O skewed right
O normal distribution
The distribution of set A is a normal distribution
The data in set A is given as:
1 3 3 2 4 0 4 3 3 5 2
Represent the dataset as a plot, as follows
0
1
2 2
3 3 3 3
4 4
5
Notice that the plot above increase from 0, then reaches a maximum at 3, and then decreases from 3 to 5
This implies that it follows a bell curve.
When a distribution follows a bell curve, such data is a normal distribution.
Hence, the distribution is a normal distribution

The point where the graph intersects the y-axis represents the beginning of the
Answer:
the origin
Step-by-step explanation:
A coordinate grid has two perpendicular lines, or axes, labeled like number lines. The horizontal axis is called the x-axis. The vertical axis is called the y-axis. The point where the x-axis and y-axis intersect is called the origin.
X + 2y = 7
2x + y = 5
What’s the substitution
You can subtract 2y from both sides of the first equation and then plug that (x = 7 -2y) into the second one to get:
14 - 4y + y = 5 -->
14 - 3y = 5 -->
-3y = -11 -->
y = 11/3 -->
x = 2/3

(DOES NOT BELONG) Is Rational
(DOES NOT BELONG) Is not Irrational
(DOES NOT BELONG) Is not an integer
(DOES NOT BELONG) Not a Whole
(DOES NOT BELONG) Not Natural
Step-by-step explanation:
This is a fraction with a square root.
Fractions:
Are Not Whole (square root cancels this)
Are Rational BUT since this has a square root, it is not.
Are not natural
Are not integers (Whole numbers that ARE NOT fractions)
So basically from what I have learned, square root cancels literally everything.

You bought 100 shares of stock at $15 per share. You sold your 100 shares at $21.75 per share. Calculate your total profit from the sale.
Answer:
$675
Step-by-step explanation:
You multiply 15 and 100 answer for that is 1500 then you multiply 21.75 and 100 answer for that is 2175 finally you subtract 1500 from 2175 witch gives you the final answer of 675
Total profit from the sale of 100 shares is equals to $675.
What is profit?
" Profit is the amount of money or revenue which we earned when selling price of a product is more than its cost price."
Formula used
Profit = Selling price - Cost price
According to the question,
Cost price of 1 share = $15
Therefore,
Cost price of 100 shares = 15 × 100
= $1500
Selling price of 1 share = $21.75
Selling price of 100 shares = 21.75 ×100
= $2175
Selling price > Cost price
Therefore , Profit
Substitute the value in the formula we get,
Profit = 2175 - 1500
= $675
Hence, total profit from the sale of 100 shares is equals to $675.

Which equation best represents the model?
Helpppppppp pleaseeeeee
Answer:
negative
Step-by-step explanation:
okay so look at the rise and the run of this line (that is given). slope is defined as rise divided by run. the "rise" is the change in y values, while the "run" is the change in x values. the rise in this problem is -4, as shown on the graph. the run is 3, as also shown there. therefore, the slope is -4/3. the type of slope this is is negative slope because the slope is clearly negative.
Answer:
-4/3
Step-by-step explanation:
(-1 - 3)/(1 - -2)
use the slope formula (y2 - y1)/(x2 - x1)

80%
Answer:
80%
Step-by-step explanation:
There are 4 shaded sections and 1 unshaded section, so five sections in total.
4 sections are shaded, so the fraction would be 4/5.
Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).
Answer:
D. 80%
Step-by-step explanation:
Well, the diagram shows 4/5ths knowing this is more than half we can auto matily mark out the first two A. and B. leaving C. 75% and D. 80% and D. is the best choice (sorry go too lazy to explain...)

what is the slope and y-intercept of y=4x+2
Answer:
slope: 4
y-intercept: 2
Step-by-step explanation:
We are given an equation, y = 4x + 2, and we are asked to find the slope and y-intercept of the line. Looking carefully, we can see that the equation is given to us in slope-intercept form.
Slope-intercept form is:
y = mx + b
where m is the slope and b is the by-intercept.
Knowing this, we can find that 4 is the slope of the line and 2 is the y-intercept.

Find the variation constant and an equation of variation for the given situation.
y varies directly as x, and y = 7 when x = 1/2.
Answer:
[tex]\displaystyle y=14\cdot x[/tex]
Step-by-step explanation:
Directly Proportion
It's said that y varies directly proportional as x, if:
[tex]y=k\cdot x[/tex]
Where k is a constant of proportionality.
We know that y=7 when x=1/2.
Using the above condition, we can find the value of k:
[tex]\displaystyle 7=k\cdot \frac{1}{2}[/tex]
Solving for k:
k=14
Thus, the equation is:

6.4n + 10= 4.4n - 6
Could you help? Thanks
Answer:
n=-8
Step-by-step explanation:
6.4n + 10= 4.4n -6
Subtract 4.4n on both sides
You then have 2n+10=-6
Subtract 10 on both sides You then have 2n=-16
Divide both sides by 2
n= -8
Hoped that helped
Answer: n= -8
Step-by-step explanation:
Get all the n's on one side, all the regular numbers on the other
Add or subtract from both sides
6.4n -4.4n +10 = 4.4n -4.4n -6 So 4.4n -4.4n = 0, "cancels' on right
2.0n +10 -10 = -6 -10 10's cancel on the left. -6-10 .=-16 on right
2n = -16 (.0 is not needed in 2.0) Divide both sides by 2
n = -8
