Draw two symmetric (not skewed) with the same means but different standard deviations. Explain the similarities or differences in means and standard deviations.
Answer: See the diagram below
There are infinitely many ways to do this. So there isn't one set answer. However, all of the answers have these properties in common.
The center peak points are at the same locationOne distribution is more narrow than the other, or one is more wider than the other.In the diagram below, I've made distribution B wider and more spread out compared to distribution A. Distribution B has a higher standard deviation. The larger the standard deviation is, the more spread out the data values will be. Standard deviation is always some positive number.
Both distributions are centered at 0, which is the mean. You could change the center to whatever you want, but make sure both distributions have this same center value.
As the diagram shows, each curve is symmetric about the center point. The left half can be reflected over the center line to get the right half, and vice versa. The curves peak at the center because this is where the majority of the data values are located. As you move to either end, the curve levels off to indicate not as many individuals are found here.

Which have more factors 125 or 200?
Answer:
200
Step-by-step explanation:
The factors of 125 are 1, 5, 25, and 125.
The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200.

Answer:
[tex]-2a^2-2a+11[/tex]
Step-by-step explanation:
To solve the question, use the given values of the variables and substitute them into the given expression.
We know that [tex]C = 2a^2-5[/tex] and [tex]D = 3-a[/tex]. With these values, we need to find [tex]2D-C[/tex]. So, substitute [tex]2a^2-5[/tex] for the [tex]C[/tex] and [tex]3-a[/tex] for the [tex]D[/tex] in that expression. Then, solve:
[tex]2D-C\\\\= 2(3-a)-(2a^2-5)\\= 6-2a-2a^2+5\\= -2a^2-2a+11[/tex]
Thus, [tex]2D-C[/tex] equals [tex]-2a^2-2a+11[/tex].
find the hcf 8x(x - 2) -2(x - 2)
We can see both terms have a (x-2) in them.
We can also see that 8 and 2 are both even so there is a 2 in common.
This means that the gcd or hcf or whatever you call it is 2(x-2)
**Just mentioning most of the time we call it the GCD(greatest common divisor) or the GCF(greatest common factor) and almost never uses hcf :)

Please I need help it’s an emergency
Answer:
θ = 35.39°
Step-by-step explanation:
Given that,
Perpendicular, P = 27
Base, B = 38
We need to find the value of angle. Let the angle be θ. So,
[tex]\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})\\\\\theta=\tan^{-1}(\dfrac{27}{38})\\\\\theta=35.39^{\circ}[/tex]
So, the required angle is 35.39°.
Which equation has a slope: 3/2, y-intercept: –4
Answer:
The equation of the line that has a slope of 3/2 and a y-intercept of -4 is:
y=3/2x-4.
Step-by-step explanation:
You want to find the equation for a line that has a slope of 3/2 and a y-intercept of -4. First of all, remember what the equation of a line is:
y = mx+b Where: m is the slope, and b is the y-intercept
All you really have to do here is replace m with 3/2, which is the slope you gave, and replace b with -4, the y-intercept you gave, in the equation y=mx+b.
The table below gives a record of variations of the values of y with the values of x. Draw a scatter plot for the data.

a baker bought 12 pounds of flour.He used 5/6 of the flour how many pounds are left
Answer:
2 pounds are left.
Step-by-step explanation:
12 pounds divided into 6 parts (or sixths) = 2 pounds each. 5 of those 6ths were used, so 10 pounds used. 2 pounds are left.
Alternately, multiply 12 x 5 for your numerator = 60, divide by 5, your denominator, and get 10 pounds used.

Annabelle invested $5,900 in an account paying an interest rate of 2% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $7,440?
Answer:
Step-by-step explanation:
Continuous compounding has the form
[tex]A=Pe^{rt}\\ \\ t=\frac{ln\frac{A}{P}}{r}\\ \\ t=\frac{ln\frac{7440}{5900}}{0.02}\\ \\ t\approx 11.6\\ \\ t=12[/tex]
Therefore it will take 12 years for the value of the account to reach $7,440.
What is Compound Interest ?Compound interest (or compounding interest) is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.
Annabelle invested amount $5900
Final Amount $7440
Rate = 2% compounded continuously
When compounded Continuously ,
[tex]\rm A = P e^{rt}\\\\\\t=\dfrac{ln \frac{A}{P}}{r}\\\\\\\\t=\dfrac{ln \frac{7440}{5900}}{0.02}\\\\t= 12[/tex]
it will take 12 years for the value of the account to reach $7,440.

Luis is shopping for gifts. Mugs are on sale for $4 off the regular price,p. Luis vuys 6 muga. H epays $54. What is the regular price of the mug? Show your work.
Answer:
13
Step-by-step explanation:
Divide the total amount he paid by the amount of mugs he bought to find out how much each mug cost.
54 ÷ 6 = $9
Each mug is nine dollars, INCLUDING THE SALE which is $4 off.
Add $4 to $9 to find the regular price
$4 + $9 = 13
The regular price of the mugs based on the given equation will be $13.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation.
Suppose the regular price is x.
Selling price = $4 off of x = x - 4
Number of mugs buys = 6
Paid = $54
54= 6 (x - 4)
(x - 4) = 9
x = 13
Hence "The regular price of the mugs based on the given equation will be $13".

Find the measure of angle B and angle C.
Answer:
angle B is 135 degrees and angle c is 45 degrees
Can someone please help meeeee
Answer:
45°
Step-by-step explanation:
The angle with measure of 9x and the angle with measure of 3x are supplementary
9x + 3x = 180°
12x = 180 divide both sides by 12
x = 15
The angle with measure of 9x and angle a are supplementary as well
9x + a = 180
9×15 + a = 180
135 + a = 180 subtract 135 ftom both sides
a = 45°
