The standard deviation of the number of residents in the sample who were born in Colorado is 7.82

Standard deviation:

The measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists is know as standard deviation.

Given,

According to 2015 census data, 42.7 percent of Colorado residents were born in Colorado. if a sample of 250 Colorado residents is selected at random.

Here we need to find the standard deviation of the number of residents in the sample who were born in Colorado.

Here we know that following details,

Number of sample = 250

Estimated proportion for residents born in Colorado = 42.7% which is equal to = 0.427.

Let us consider X be the random variable of interest (number of residents in the sample), on this case we now that:  

X ~ (n = 250, p = 0.427)

Now, according to the probability mass function for the Binomial distribution is given as:  

E(X) = n x p = 250 x 0.427 = 106. 75.

Now, the standard deviation for the random variable is given by:

SD = √106.75 (1 - 0.427)

SD = √106.75(0.563)

SD = 7.82

Therefore, the standard deviation is 7.82.

Answer:

Step-by-step explanation:

This seems complicated, huh.  

So think about the question.  They want to know the distance from a line, to a point.  first decide if the point could possibly be on the line and there is zero distance.   The given point is at  (-1, 7)    our coordinates of the point are at  -1 in the X direction and at 7 in the Y direction.  If we were to plug in those two number into the given line equation,   y = 3x  would it be a true statement?  no.    7 = 3(-1)  is not true.   so our given point is not on the line.  Next,  find the right angle to the line and point.  make your own line equation that does have our given point in it.  and is at a right angle to the given line.    recall that using a reciprocal can give you a right angle to your line.  y = (- 1/3)X .  Now we just need the given point to plug into our made up line equation and be true.    7 = (-1/3)(-1) + b    .  we need to make this equation true by moving a number into "b" that makes it true.

b = 6[tex]\frac{2}{3}[/tex]  or [tex]\frac{20}{3}[/tex]

7 = (-1/3)(-1) + [tex]\frac{20}{3}[/tex]

now, when does our made up line, y =(-1/3)x + [tex]\frac{20}{3}[/tex], intersect with the given line, y=3x,  that is,  set the two equal

3x = (-1/3)x + [tex]\frac{20}{3}[/tex]

3[tex]\frac{1}{3}[/tex] X = [tex]\frac{20}{3}[/tex]

[tex]\frac{10}{3}[/tex]X = [tex]\frac{20}{3}[/tex]

X=[tex]\frac{20}{3}[/tex] * [tex]\frac{3}{10}[/tex]

X = [tex]\frac{20}{10}[/tex]

X=2

our two equations intersect at 2,  how handy  :)

now we have our two points that are at a right angle from each other and we just need the distance from them

(given) A(-1,7)   and (found) B(2,6)

Distance = [tex]\sqrt{(x2-x1)^{2} + (y2-y1)^{2} }[/tex]

then our given points are A(x1,y1)  and B(x2,y2)

Distance = [tex]\sqrt{(2-(-1))^{2}+(6-7)^{2} }[/tex]

Distance =[tex]\sqrt{3^{2}+(-1)^{2} }[/tex]

Distance = [tex]\sqrt{9+1}[/tex]

[tex]{ \red{ \sf{5}}}{ \green{ \sf{x}}} = { \red{ \sf{74}}}[/tex]

Divide both the sides by 5. then,

P (or Q) and mark an arc roughly where M's reflection across AB is located.

One tool for drawing circles is a compass. According to the circle's radius, which is drawn with a compass, the sizes of the circles vary.

A compass's handle is held in place by our thumb and forefinger. A circle is typically drawn using just one hand. Between the forefinger and thumb, the compass is turned.

Around this point, the pencil tip is rotated. The circle's radius is determined by the distance between the pencil tip and the compass needle. A ruler is used to set it. The gap can be adjusted by adjusting the angle between the compass's arms.

At that point of reflection (M'), arcs drawn from P and Q in M's approximate location across AB will intersect. As desired, the line passing through point M and perpendicular to AB will connect M and M'.

⇒Note there was a 2x-5 in the numerator and a 2x-5 in the denominator so they canceled each other. Leaving the above expression.

The variable y vary directly with respect to x , and the equation to denote this direct variation is y = 1.375 x .

From the table we can see that the values of x are 8 for the y value of 11

Any direct variation is represented by the equation :

y = k x , where k is a constant

now we put the values of x and y in the equation to calculate k

11 = k × 8

or, k = 11 / 8 = 1.375

again , at x = 16 , y is 22

∴ k = 22/16 = 1.375

Hence the equation for direct variation will  be given by

y = kx

or, y = 1.375 x

When one quantity changes directly in reaction to a change in another quantity, this is a type of proportionality known as "direct variation." This implies that if one quantity rises, the other will rise correspondingly as well.

Like in the previous illustration, if one quantity decreases, the other quantity also decreases. Direct variation will have a linear relationship with the graph, resulting in a straight line.

Answer:

Step-by-step explanation:

Ignore the (2,2) just use (-2,1) and (-4,2)

a = amount invested at 8%

how much is 8% of "a"? (8/100) * "a", namely 0.08a.

b = amount invested at 6%

how much is 6% of "b"? (6/100) * "b", namely 0.06b.

we know the total amount invested is 210000, so whatever "a" and "b" might be, we know that a + b = 210000.

we also know that the yielded amount in interest is the same for both, so whatever 0.08a and 0.06b are, we know they're the same.

[tex]\begin{cases} a+b=210000\\\\ 0.08a=0.06b \end{cases}\hspace{5em}a+b=210000\implies b=210000-a \\\\\\ \stackrel{\textit{substituting on the 2nd equation}}{0.08a~~ = ~~0.06(210000-a)}\implies 0.08a=12600-0.06a\implies 0.14a=12600 \\\\\\ a=\cfrac{12600}{0.14}\implies \boxed{a=90000}\hspace{9em}\boxed{\stackrel{210000~~ - ~~90000}{b=120000}}[/tex]

By finding the slopes of the two segments we can see that the segments are not parallel nor perpendicular.

The slope for a segment whose endpoints are:

(x₁, y₁) and (x₂, y₂) is:

slope = (y₂ - y₁)/(x₂ - x₁)

Two segments are:

Segment AB has endpoints (-1, -1) and (1, 5), so the slope is:

s = (5 + 1)/(1 + 1) = 3

For segment CD the endpoints are (1, 2) and (5, 4), so the slope is:

s' = (4 - 2)/(5 - 1) = 2/4 = 1/2

- Solution for 33 is what percent of 132:

- Percentage solution with steps:

Step 1: We make the assumption that 132 is 100% since it is our output value.

Step 2: We next represent the value we seek with "x".

Step 3: From step 1, it follows that 100%=132

Step 4: In the same vein, x%=33

Step 5: This gives us a pair of simple equations:

100%=132(1)

x%=33(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left-hand side) of both equations have the same unit (%); we have

100%/x% = 132/33

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100%=33/132

Part a

The equation of the function is y = ( - 0.7/277)x + 16

Part b

The slope of the line =  - 0.7/277 and the y intercept of the line = 16

From the table

Choose two points

(242, 14.8) and (519, 14.1)

The slope of the line m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values in the equation

The slope of the line = (14.1 - 14.8) / (519 - 242)

= -0.7 / 277

The slope of the line = - 0.7/277

From the table at x = 0, the value of y = 16

Therefore the y intercept is 16

The slope intercept form is

y = mx + b

Substitute the values in the equation

y = ( - 0.7/277)x + 16

Part b

The slope of the line =  - 0.7/277

The y intercept of the line = 16

Hence, from the given table
