The distribution A must has a smaller standard deviation. So, option C is correct.
What does "normal" describe in statistics?Normal usually refers to the word "normal" in normal distribution.
The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from mean, its chances decrease.
If we've got a normal distribution, then we can convert it to a standard normal distribution and its values will give us the z score.
If we have
[tex]X \sim N(\mu, \sigma)[/tex]
(X is following a normal distribution with mean and standard deviation )
then it can be converted to a standard normal distribution as
[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]
Normal curve A has a wider distribution than Normal curve B.
The distribution A must has a smaller standard deviation.

WILL MARK BRAINLIEST
Answer:
C (3, 4 )
Step-by-step explanation:
slope is calculated as
m = [tex]\frac{vertical}{horizontal}[/tex] between 2 points on a line
m = - [tex]\frac{2}{9}[/tex]
means a change of - 2 in the vertical and + 9 in the horizontal
A (- 6, 6 ) → (- 6 + 9, 6 - 2 ) → (3, 4 )

Here, we are given with an equation in which we are given with some constants and two same variables x. We are said that the LHS and RHS are equal to each other. We are asked to find the value of the variable x. To find the value of x, we use an other concept which helps us to find the value of x and also to verify our answer. This concept is called as the transposition method. While using this method, the sign of the appropriate number or variable changes. We use this method to shift the numbers and variables on two separate sides. We can also verify our answer at the end of our answer by verification method. So, let's solve!!
[tex]\:[/tex]
➤ Solution :-[tex]{\sf \leadsto 4x - 9 = 2x + 7}[/tex]
Shift the variable value to LHS and the constant value to RHS, changing it's sign.
[tex]{\sf \leadsto 4x - 2x = 7 + 9}[/tex]
Subtract the values on LHS and add the values on RHS.
[tex]{\sf \leadsto 2x = 16}[/tex]
Shift the number 2 from LHS to RHS.
[tex]{\sf \leadsto x = \dfrac{16}{2}}[/tex]
Simplify the fraction to find the value of x.
[tex]{\sf \leadsto x = 8}[/tex]
[tex]\:[/tex]
[tex]{\red{\underline{\boxed{\bf So, \: the \: value \: of \: x \: is \: 8.}}}}[/tex]
━━━━━━━━━━━━━━━━━━━━━━━
Verification :-[tex]{\sf \leadsto 4x - 9 = 2x + 7}[/tex]
Substitute the value of x.
[tex]{\sf \leadsto 4(8) - 9 = 2(8) + 7}[/tex]
Multiply the numbers in the bracket.
[tex]{\sf \leadsto 32 - 9 = 16 + 7}[/tex]
Subtract the values on LHS and add the values on RHS.
[tex]{\sf \leadsto 23 = 23}[/tex]
So,
[tex]{\sf \leadsto LHS = RHS}[/tex]

1Convert the following equation to slope-intercept formy-3=\frac{1}{8}\left(x+8\right)y−3=8(x+8)
Answer:
y = 8x + 67
Step-by-step explanation:
The equation of a line in slop- intercept form is
y = mx + c
Given
y - 3 = 8(x + 8) ← distribute parenthesis
y - 3 = 8x + 64 ( add 3 to both sides )
y = 8x + 67 ← in slope- intercept form
Given the parent function f(x)=1x , match each transformed function with it transformation.

Why do we use standard form?
Answer:
Standard Form is useful because a lot of times as it's helpful to find the x and y intercepts. And it also gets to be useful once you start studying quadratics which is when you have x squared. However most of the time people like to use equations that are either in point slope form or slope intercept form.

all i know is that this is the equation √(24x5-8)
I need help checking the answer to it.
I think it's 10.583005244
I'm not sure and i need all teh help i can get, thanks
Answer:
Take the square root of a number that is not a perfect square. None of the numbers are perfect squares. After you do that you can do any closed operation you want with the resulting irrational and the two other rationals and you will end up with an irrational.
8*24*√5 is an example.
8+24+√5 is another
5*√8 + 24 is another.
If you take the cube root of any number that isn't a perfect cube you get an irrational, so you could take the cube root of 5 or 24 instead of the square root and do the same thing.

-1/3(9x-18)+8x simplified. Please awnser my question quick I need it!!
Answer:
5x-6
Step-by-step explanation:
Multiply 9x and 18 with -1/3
-1/3 times 9x is -3x
-1/3 times 18 is -6
So the equation looks like this:
-3x-6+8x
8x plus -3x is 5x
So the answer is: 5x-6

Write a function g whose graph is a translation 3 units to the left of the graph of f.
Answer:
f(x) = (x + 3)
Step-by-step explanation:
when it's in the parentheses, it's the opposite so in this if it's saying 3 units to the left, it would be subtracting or negative so to make it the opposite u do x + 3 in parentheses
