Solve the problem. A variable x has the possible observations shown below. Possible observations of x: -3 -1 0 1 1 2 4 4 5 Find the z-score corresponding to an observed value of x of 2.
Answer:
The z-score corresponding to an observed value of x of 2 is 0.215.
Step-by-step explanation:
We are given that a variable x has the possible observations shown below;
Possible observations of X: -3, -1, 0, 1, 1, 2, 4, 4, 5.
Firstly, we will find the mean and the standard deviation of X, i.e;
Mean of X, ([tex]\mu[/tex]) = [tex]\frac{\sum X}{n}[/tex]
= [tex]\frac{(-3)+ (-1)+ 0+ 1+ 1+ 2+ 4+ 4+ 5}{9}[/tex]
= [tex]\frac{13}{9}[/tex] = 1.44
Standard deviation of X, ([tex]\sigma[/tex]) = [tex]\sqrt{\frac{\sum (X-\bar X)^{2} }{n-1} }[/tex]
= [tex]\sqrt{\frac{(-3-1.44)^{2}+(-1-1.44)^{2}+......+(4-1.44)^{2}+(5-1.44)^{2} }{9-1} }[/tex]
= 2.603
Now, the z-score corresponding to an observed value of x of 2 is given by;
z-score = [tex]\frac{X-\mu}{\sigma}[/tex]
= [tex]\frac{2-1.44}{2.603}[/tex] = 0.215.

Answer:
[tex]\huge\boxed{Center= (-3,4) , Radius = 5\sqrt{2} }[/tex]
Step-by-step explanation:
Given equation is
[tex]x^2 + y^2 + 6x-8y - 25 = 0[/tex]
Adding 25 to both sides
[tex]x^2 + y^2 +6x-8y = 25[/tex]
Completing squares
[tex]x^2 +6x +y^2 - 8y = 25\\(x)^2-2(x)(-3) + (y)^2 - 2(x)(4) = 25[/tex]
Both of their "b" is -3 and 4 respectively
So, adding (-3)² => 9 and (4)² => 16 to both sides
[tex](x+3)^2 + (y-4)^2 = 25 + 9 + 16\\(x+3)^2 + (y-4)^2 = 50\\(x-(-3))^2 + (y-4)^2 = (5\sqrt{2)^2}[/tex]
Comparing it with [tex](x-h)^2+(y-k)^2 = r^2[/tex], where center = (h,k) and radius = r.
We get:
Center = (-3,4)
Radius = [tex]5\sqrt{2}[/tex]

Total employment for metal workers in 2019 is projected to be 210,000. If this is a 5% increase from 2009, approximately what was the total employment in 2009?
Answer:
200,000
Step-by-step explanation:
To solve this, you can divide the 2019 total projected employment (210,000) by 1 + the growth rate (.05) to find the 2009 total employment.
210,000 / (1 + .05) = 200,000

A total of 438 tickets were sold for the school play. They were either adult tickets or student tickets. There were 62 fewer student tickets sold than adult tickets. How many adult tickets were sold?
Answer:
a + s = 394 total tickets sold is 394 s = a - 56 56 fewer student tickets than adult substitute a-56 in place of s in 1st equation and solve for a a + (a - 56) = 394 2a - 56 = 394 2a = 450 a = 225 adult tickets sold s = a-56 = 169 student tickets sold

To save for her newborn son's college education, Kelli Peterson will invest $1,500.00 at the end of each year for the next 18 years. The interest rate she expects to earn on her investment is 9%. How much money will she have saved by the time her son turns 18?
Answer:
9% of $1500 is $15 so she gains an extra $15 for each of the 18 years
$1500 in the bank each year for 18 years is $27000 after 18 years
$15 each year as well so that’s an extra $270 in the bank
The total in the bank is the sum of what she has invested and the interest so the total in the bank is $27270

Find the equation of the line perpendicular to y=2x-6 that passes through the point (1,5). If possible, write the equation in slope-intercept form.
Answer:
[tex]y=-0.5x+4.5[/tex]
Step-by-step explanation:
The slope of [tex]y=2x-6[/tex] is:
[tex]2[/tex]The negative reciprocal of that slope is:
[tex]m=-\frac{1}{2}[/tex]So the perpendicular line will have a slope of [tex]-1/2[/tex]:
[tex]y - y_1 = (-\frac{1}{2} )(x - x_1)[/tex]And now put in the point [tex](1,5)[/tex]:
[tex]y-5=(-\frac{1}{2})(x-1)[/tex]And that answer is OK, but let's also put it in [tex]y=mx+b[/tex] form:
[tex]y-5=-\frac{x}{2}+\frac{1}{2}[/tex][tex]y=-\frac{x}{2}+\frac{11}{2}[/tex][tex]y=-0.5x+4.5[/tex]Find an equation of the line passing through the point (−3,−7) that is perpendicular to the line y= −5x+4
Answer:
y = 1/5x - 6.4
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the slope will be 1/5
Then, plug the slope and the point into the equation y = mx + b to find b
y = mx + b
-7 = 1/5(-3) + b
-7 = -0.6 + b
-6.4 = b
Then, plug this and the slope into the equation
y = 1/5x - 6.4 will be the equation

Suppose Q is the midpoint of PR. Use the information to find the missing value.
11) PQ = 3x + 14 and QR = 7x - 10 x =
Answer:
x = 6
Step-by-step explanation:
Given that PQ = 3x + 14, QR = 7x - 10, and Q is the midpoint of PR, it means Q is equidistant from both endpoints of P and Q. In order words, the distance from P to Q is the same as the distance from Q to R.
Therefore, PQ = QR. Which is:
[tex] 3x + 14 = 7x - 10 [/tex]
Solve for x. Collect like terms
[tex] 3x -7x = - 14 - 10 [/tex]
[tex] -4x = -24 [/tex]
Divide both sides by -4x
[tex] x = 6 [/tex]

the perimeter of a rectangle is 12cm. If the length is 2 less than 3 times the width, find the length
Answer:
The length of the rectangle would be 4.
Step-by-step explanation:
We can start by naming the width x.
Therefore, the length would 3x-2.
The perimeter of the rectangle would then be:
2(3x-2+x)
We can set up the given equation
2(3x-2+x)=12
Solve for x.
Divide both sides by 2.
3x-2+x=6
Combine like terms.
4x-2=6
Add 2 to both sides.
4x=8
Divide both sides by 4.
x=2
The width would then be 2.
We can plug that into the expression for length.
3x-2
3(2)-2
6-2
4
The length of the rectangle would be 4.

Solve M= 2HA + 2HT for H.
Answer:
H = M/(2A +2T)
Step-by-step explanation:
Factor out H and divide by its coefficient.
M = 2HA +2HT
M = H(2A +2T)
M/(2A +2T) = H
H = M/(2A +2T)
The value of β is:
60º
45º
90º
30º
75º
Answer:
60°
Step-by-step explanation:

cos(β) = 3/6 = 1/2
β = arccos(1/2) . . . . use the inverse cosine function to find the angle
β = 60°
_____
The ratio of side lengths in a 30°-60°-90° triangle (one of the "special" triangles), is ...
1 : √3 : 2
The 2 : 1 ratio of longest to shortest side in this right triangle is a clue that the largest acute angle is 60°. It also tells you that x = √3 times the short side length, so is x = 3√3.

Answer:
Remainder = (3145/8)x - 408
Step-by-step explanation:
We want to find the remainder when 6x^(5) + 4x⁴ - 27x³ - 7x² + 27x + 3/2 is divided by (2x² - 3)²
Let's expand (2x² - 3)² to give ;
(2x - 3)(2x - 3) = 4x² - 6x - 6x + 9 = 4x² - 12x + 9
