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

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:
[tex]\boxed{\displaystyle y=14\cdot x}[/tex]
What does the - 8 do in the function k(x)?
k(x) = x^2 - 8
Answer:
the negative 8 is the y-intercept of the equation. This means that this is y value of where 0 is on the x-axis. The point for the y-intercept is (0,8)

Find the value of x.
55°
79°
110°
x°
Answer:
i think its 158
Step-by-step explanation:
i think what theyre doing here is a pattern because
79-55=24 and 110-79=31 which has no pattern but when u subtract 55 from 110 you get 110-55=55 so i just multiplied 79 by 2 getting the answer 158.
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

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.

Answer:
I believe the answer is about 1/2!
Step-by-step explanation:
I don't have a step-by-step but when I took a test this question was on it and I got the question right by putting about 1/2!
The probability of her catching a trout is 6/25
What is probability ?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
According to the question
based on given condition , formulate
24 ÷ (23 + 12 + 24 + 41)
Calculate sum or difference = 24/23 + 12 + 24 + 41
Calculate sum or difference = 24/59 + 41
Calculate sum or difference = 24/100
Reduce the fraction = 6/25
Hence, the probability of her catching a trout is 6/25

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.

3x - 4 + 6x = -31
17 = 3x - 10
2x + 6 = 4x - 8
17x - 5(3x - 11) = 41
5x - (3x - 6) = 18
6x - 3(4 - 5x) = 30
x - (-5) = 7
This is a lot of questions-
I did them all on a calculator.
1.)
3x - 4 + 6x = -31
3x + 6x - 4 = -31
9x - 4 = -31
9x = -27
Answer: x= -3
2.)
17 = 3x - 10
3x -10 = 17
-10 = -10
3x = 27
divide both sides by 3
Answer: x= 9
3.)
2x + 6 = 4x - 8
-6 = -6
2x = 4x -14
-4x (both sides)
-2x = -14
divide both sides by -2
Answer: x = 7
4.)
17x - 5(3x - 11) = 41
2x +55 = 41
-55 (both sides)
2x = -14
divide 2 both sides
Answer: x = -7
5.)
5x - (3x - 6) = 18
2x + 6 = 18
-6 both sides
2x = 12
divide both sides by 2
Answer: x = 6
6.)
6x - 3(4 - 5x) = 30
21 - 12 = 30
+12 boh sides
21x = 42
divide both sides by 21
Answer: x = 2
7.)
x - (-5) = 7
x + 5 = 7
-5 both sides
Answer: x = 2
