HELP SAVE ME I NEED U GIRL

Answer:

The answer is B.

Step-by-step explanation:

The standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution.

Formula of the standard error of the means is standard deviation divided by square root of the sample size.

SE = δ/√n

This formula also gives the standard deviation of the sample means.

The answer is standard deviation of the sample (B).

For example, "The notation for standard error can be any one of SE, SEM (for standard error of measurement or mean)."

Answer:

24 cm²

Step-by-step explanation:

Z zadanego powyżej pytania uzyskano następujące dane:

Obwód (obwód) = 32 cm

Wysokość (h) = 3 cm

Obszar rombu (A) =?

Następnie określimy długość boku rombu. Można to uzyskać w następujący sposób:

Obwód, czyli obwód (P) = 32 cm

Strona (y) =?

P = 4 s

32 = 4 s

Podziel obie strony przez 4

s = 32/4

s = 8 cm

Stąd długość boku rombu wynosi 8 cm

Na koniec określimy obszar rombu w następujący sposób:

Długość boków = 8 cm

Wysokość (h) = 3 cm

Obszar rombu (A) =?

A = sh

A = 8 × 3

A = 24 cm²

Dlatego obszar rombu jest

24 cm².

For this case, what we must do is solve the following system of equations:  tan (50) = h / x  tan (40) = h / (x + 50)  

Solving the system we have:  (x + 50) * tan (40) = h  (x) * tan (50) = h  

Matching:  (x + 50) * tan (40) = (x) * tan (50)  

Rewriting:  x (tan (50) - tan (40)) = 50 * tan (40)  x = 50 * tan (40) / (tan (50) - tan (40))  x = 118.9692621  

Substituting:  h = (x) * tan (50)  h = (118.9692621) * tan (50)  h = 141.7820455

Answer:

F=6*24/8.....F=6*3=18

Given:

Consider the three point of second line are S, R, V instead of S, R, W.

A line with points T, R, W intersects a line with points S, R, V at point R. Another line extends from point R to point U between angle T, R, V.

[tex]\angle VRW=(3x)^\circ[/tex]

[tex]\angle TRS=(2x+18)^\circ[/tex]

To find:

The m∠SRW.

Solution:

The figure according to the given information is shown below (not to scale).

From the below figure it is clear that, [tex]\angle VRW[/tex] and [tex]\angle TRS[/tex] are vertically opposite angles. So, their measures are equal.

[tex]3x=2x+18[/tex]

Subtract 2x from both sides.

[tex]3x-2x=18[/tex]

[tex]x=18[/tex]

Using x=18 the measure of angle VRW is

[tex]\angle VRW=(3x)^\circ[/tex]

[tex]\angle VRW=(3\times 18)^\circ[/tex]

[tex]\angle VRW=54^\circ[/tex]

Now,

[tex]\angle VRW+\angle SRW=180^\circ[/tex]       [Linear pair]

[tex]54^\circ+\angle SRW=180^\circ[/tex]

[tex]\angle SRW=180^\circ-54^\circ[/tex]

[tex]\angle SRW=126^\circ[/tex]

Therefore, the correct option is C.

126

Answer:

y = x + 2

Step-by-step explanation:

The total cost if you buy 4 bags of Skittles is $6.

Answer:

The number is 66

Step-by-step explanation:

Since 44 is two thirds of a number, 44/x = 2/3

If you multiply the numerator and denominator of 2/3 by 22, you get 44/66

Since 44/x = 44/66,

x=66

If 44 is 2 thirds of a number, then the number is 77.

We can solve this problem by setting up the following equation:

2/3 * x = 44

Where x is the unknown number.

To solve for x, we can multiply both sides of the equation by 3/2. This gives us the following equation:

x = 44 * (3/2)

Simplifying the right side of the equation, we get x = 77.

Therefore, the number is 77.

Here is the solution in more detail:

Define the variables.

x: The unknown number.

Set up the equation.

We know that 2/3 of the number is 44, so we can set up the equation 2/3 * x = 44.

Solve for x.

To solve for x, we can multiply both sides of the equation by 3/2. This gives us the equation x = 44 * (3/2).

Simplifying the right side of the equation, we get x = 77.

The answer.

Therefore, the number is 77.

Answer:

C) Explain how the equations are equal and just prove it with a check or just plug in a number like for ex: x=1 and I checked with both and it equals out.

d) Use inverse operations (or you can say do the order of operations in reverse and then use invers operations), provide an example if you think what you said doesn’t make sense, like for

Ex: 2x-1=43+5x

     2x=44+5x (add the -1)

     -3x=44  (subtract 5x to both sides)

       X=44/-3 (isolate the variable by dividing 3 on both sides)

An example is always better

E) Just use inverse operations and solve it like what you would normally do

~ Simply keep the "7" in the place where "x" is there.

[tex]f(7) = \frac{7}{7} [/tex]

Therefore, X= 1.

Hope it helps....

Answer:

After evaluating the function [tex]f(x)=\frac{x}{7}[/tex] by putting x = 7, we get f(7)= 1

Step-by-step explanation:

We need to evaluate the function [tex]f(x)=\frac{x}{7}[/tex] and find f(7)

For finding f(7) we will put x = 7 in the given function [tex]f(x)=\frac{x}{7}[/tex]

So, putting x= 7 and finding f(7)

[tex]f(x)=\frac{x}{7}\\Put\:x=7\\f(7)=\frac{7}{7}\\f(7)=1[/tex]

So, after evaluating the function [tex]f(x)=\frac{x}{7}[/tex] by putting x = 7, we get f(7)= 1

Answer:

$159.1

Step-by-step explanation:

Given that:

Original price of surfboard = $199

Reduction of price done = 10%

Then a coupon is used by a customer for $20 off.

To find:

How many dollars were paid by the customer?

Solution:

First of all, let us find the price after the reduction of 10% from the original price.

10% of $199 = [tex]\frac{10}{100}\times 199 = \$19.9[/tex]

This price is reduced from the original price.

Price after reduction = $199 - $19.9 = $179.1

Now, again there is coupon of $20.

Therefore, final price that the customer had to pay = $179.1 - $20 = $159.1
