Normal curve A has a wider distribution than Normal curve B. The distribution A must has ____________.
A. a smaller mean
B. a larger standard deviation
C. a smaller standard deviation
D. a larger mean
Answers
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]

What is a cubic polynomial function in standard form with zeros 3 –2 and 2
I really need help with this. At least just a nudge.
Thanks
Answers
Answer:
x^3 - 3x^2 - 4x + 12
Step-by-step explanation:
Okay, so let's work backwards.
3, -2, 2 are the zeros, so we can use these numbers write the equation in factored form. (For right now, as a placeholder, I'll let y = 0)
(x - 3)(x + 2)(x - 2) = 0
If you want to check this, you can insert each of the zeros into the expression with a constant of the opposite sign.
So now, we can just expand the factored form. (I'll be doing this one equation at a time)
(x - 3)(x + 2) = x^2 + 2x - 3x - 6 = x^2 - x - 6
(x^2 - x - 6)(x - 2) = x^3 - 2x^2 - x^2 + 2x - 6x + 12 = x^3 - 3x^2 - 4x + 12
So,
The equation in standard form is x^3 - 3x^2 - 4x + 12
(Don't take my word for it though, now that I've told you how, feel free to do it on your own)

A bank teller s two customers. Jerry makes a $20
withdrawal, so his balance changes by -$20. Hank makes
a $5 deposit, so his balance changes by $5.
Use absolute value to show the size of each transaction. Which transaction
involves more money?
O A. Hank’s deposit involves more money, because -20 is greater than
5.
O B. Hank’s deposit involves more money, because 1-20 is greater than
151
O C. Jerry’s withdrawal involves more money, because 1-20 is greater
than 51
O D. Jerry’s withdrawal involves more money, because 1-20 is less
than 151
Answers
Jerry's withdrawal involves more money because |-20| is greater than |5|
The vertical bars represent absolute value.
======================================================
Explanation:
Absolute value is the distance a number is from 0. I recommend drawing out a number line. You should see that -20 is further from zero compared to 5.
So this is a visual representation of why Jerry is dealing with more money. You can think of the positive version of each value, which is effectively what absolute value is doing, when comparing the values.
-20 becomes 205 stays at 5We see that 20 > 5, so Jerry is dealing with more money even though he's losing it rather than gaining it.

Equation of line p is y=x+7. Equation of a is y=-x+11. Prove that the lines are perpendicular
Answers
Answer:
The Answer is provided in the explanation!
Step-by-step explanation:
The lines are perpendicular because in both of the equations, the x variables are inverses. Meaning, that y=x+7, the x is positive, and y=-x+11, the x is negative. This shows that the slopes of both equations are 1, meaning the graph will have an X shape, provide that lines are perpendicular because they have an inverse of the same slope!
Find the unknown sizes of angles in the following figure (please explain it):
Answers
Answer:
x = 56
MKL = 56
KML= 63
MLK = 61
Step-by-step explanation:
We know that the sum of the interior angles of a triangle = 180 degrees.
So, x+ (x+7)+ ( x+5) = 180
3x+ 12= 180
3x= 180-12 = 168
168/3 = x
therefore, x= 56 degrees.
So MKL = 56
KML= 56+ 7 = 63
MLK = 56+5 = 61
What is the value of x?

Answers
< (4x + 8) + < 72° = 180°
Combine like terms:
4x + 80 = 180°
Subtract 80 from both sides:
4x + 80° - 80° = 180° - 80°
4x = 100
Divide both sides by 4 to solve for x:
4x/4 = 100/4
x = 25
To verify whether the value of x is correct, substitute its value into the equality statement:
< (4x + 8)° + < 72° = 180°
< [4(25) + 8]° + < 72° = 180°
< (100 + 8)° + < 72° = 180°
< 108° + < 72° = 180°
180° = 180° (True statement. Therefore, the correct answer is x = 25).

The length of a rectangle is 3 meter shorter than3 times its width.Find the length and width if the perimeter is 210 meters
Answers
Answer:
length = 78 m , width = 27 m
Step-by-step explanation:
let w represent width then length l = 3w - 3
the perimeter (P) is calculated as
P = 2l + 2w = 210 , substitute values
2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side
6w - 6 + 2w = 210
8w - 6 = 210 ( add 6 to both sides )
8w = 216 ( divide both sides by 8 )
w = 27 and l = 3(27) - 3 = 81 - 3 = 78
Then length = 78 m and width = 27 m

Answers
Answer:
11 bars
Step-by-step explanation:
Clara bought 11 chocolate bars. Let x be the number of chocolate bars Clara buys.
The cost of each chocolate bar is 63p, so the total cost of x chocolate bars is 63x pence.
After buying the chocolate bars, Clara has 7p left over.
Now we can write the equation:
Total money spent on chocolate bars + Money left over = Total money Clara has initially
63x + 7 = 700 (Since £7 is equivalent to 700p)
Now, let's solve for x:
63x = 700 - 7
63x = 693
x = 693 / 63
x = 11

are 46 and 105 relatively prime
Answers
Answer:
They are relatively prime.
Step-by-step explanation:
The prime factorization of 46 is 23 * 2, and the prime factorization of 105 is
3 * 7 * 5. Since there are no common factors, they are relatively prime.
There is no common prime number. Then the numbers 46 and 105 will be relatively prime.
What is relatively prime?When two quantities have just one similar, or if there is no additional value with the same quantity as one, you cannot divide them both and obtain zero as the remainder, two numbers are considered to be relatively prime.
The numbers are 46 and 105.
Then the factor of the number 46 will be
46 = 2 × 23
Then the factor of the number 105 will be
105 = 3 × 5 × 7
There is no common prime number. Then the numbers 46 and 105 will be relatively prime.
