A. x=-1
B. x=-2
C. x=1
D. x=2
Answer:
C. x = 1
Step-by-step explanation:
Combine like terms
10 + 2 − 3 = 9
12 − 3 = 9
Add 3 to both sides of the equation
12 − 3 + 3 = 9 + 3
Add the numbers
12 = 9 + 3
12 = 12
[tex]\frac{12x}{12} = \frac{12}{12}[/tex]
Cancel terms that are in both the numerator and denominator
[tex]x = \frac{12}{12}[/tex]
Divide the numbers
x = 1
Therefore the correct answer is C. x = 1
Answer:
C. x = 1

The commutative property of addition says that changing the order of numbers does not change the sum. In this case, they both equal 8 even though the numbers are switched.
2. The weights (in pounds) of three adult males are
160, 215, and 195. The standard error of the mean of
these three weights is
(a) 190. (b) 27.84. (c) 22.73. (d) 16.07. (e) 13.13.
Answer:
(d) 16.07
Step-by-step explanation:
Step 1
We find the mean
Formula = Sum of Terms/Number of Terms
= 160+ 215 + 195/3
= 570/3
= 190
Step 2
We find the Standard Deviation
We use the formula for Sample Standard deviation =
√Mean - x/n - 1
n = 3
= √[(160 - 190)² + (215 - 190)² + (195 - 190)²]/3 - 1
= √1550/3
= √775
= 27.83882181
Approximately = 27.84
Step 3
We find the Standard Error of the mean
The formula = Standard deviation/√n
= 27.84/√3
= 16.07
Option d is correct
Based on the information given, the standard error of the mean of these three weights is 16.07.
The mean of the numbers will be:
= (160 + 215 + 195)/3
= 190
The standard deviation will be approximately 27.84.
Lastly, the standard error will be:
= 27.84 × ✓3
= 16.07

A shirt that is normally 19.95 is on sale for 20% off what is the sale price
Answer:
$15.96
Step-by-step explanation:
Sales price = $19.95
Discount = 20%
Amount paid = $19.95 - ($19.95*20%) = $19.95 - $3.99 = $15.96
Answer:
$15.96
Step-by-step explanation:
The sales price is $19.95. The discount is 20%.
$19.95 - ($19.95 × 20%)
$19.95 × 20% = $3.99
$19.95 - $3.99 = $15.96

Answer:
[tex]\sqrt{125}[/tex]
Step-by-step explanation:
Use Pythagorean theorem since you have a right triangle [tex]15^{2}[/tex] = [tex]10^{2} + x^{2}[/tex]
225 = 100 + [tex]x^{2}[/tex] so x = [tex]\sqrt{125}[/tex]
Answer:
x = 5[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² + 10² = 15²
x² + 100 = 225 ( subtract 100 from both sides )
x² = 125 ( take the square root of both sides )
x = [tex]\sqrt{125}[/tex] = [tex]\sqrt{25(5)}[/tex] = 5[tex]\sqrt{5}[/tex] ← in simplest radical form

A line is
y=mx+b where m is the slope, however we are told that this is a horizontal line, thus the slope is zero as y does not change, With zero slope y=mx+b becomes
y=b where the constant b is the value of y. We have the point (5,-7) so b=-7 and the line is
y=-7

The McDonald's Play Place is going to increase its ball pit size to allow for more fun! The ball pit was originally 10 feet by 12 feet. They have decided to increase each side by the same amount. Express the area of the new pit as a polynomial in simplest form.
Please note that I'm not 100% sure on this question!
Answer:
[tex]x^{2} + 22x + 120[/tex]
Step-by-step explanation:
The ball pit was originally 10 × 12 feet long, or a 120ft area.
We can express the areas of the side and bottom extensions as [tex]12x[/tex] and [tex]10x[/tex] respectively.
The corner adjacent to both extensions can be expressed as [tex]x^{2}[/tex].
We can put these numbers into a polynomial:
[tex]x^{2} + 12x + 10x + 120[/tex]
This polynomial can then be simplified.
[tex]x^{2} + 22x + 120[/tex]

Please help with math
Answer:
Scale factor = 3
Step-by-step explanation:
Using similar triangles
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
Expand
3x+30 = 27x-90
3x-27x = -90 - 30
-24x = -120
x = 120/24
x = 5
For the larger triangle;
AC = 3x-10
AC = 3(5)-10
AC =15-10
AC = 5
AB = x+10
AB = 5+10
AB = 15
For the scale factor;
Since AT/AG = AB/AC
9/15 = 3/5
3*3/5*3 =3/5
Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3
