Find the absolute value of each deviation from the mean
Answer:
Mean Absolute Deviation = 5.3333
Step-by-step explanation:
Xmean = 85
MAD = (85 - 85) + (92 - 85) + (88 - 85) + (80 - 85) + (91 - 85) + (74 - 85) /6
=(0) + (7) + (3) + (5) + (6) + (11) /6
= 32 /6
Mean Absolute Deviation = 5.3333
Find the area of the shape shown below.
Answer:
To find the area break up the shapes:
The rectangle is A = bh which is 7*3 which is 21.
Triangle: A = 1/2(bh)
A=1/2(3*7)
A=1/2(21)
A=10.5
Now add up the areas:
21+10.5
=
31.5
The answer is 31.5 units.

Which expression can be used to find the surface area of the following rectangular prism?
Answer:
option A
Step-by-step explanation:
Here we can see that , the dimensions of the prism ( cuboid ) is 3 × 5 × 6 . If a cuboid has dimensions of l × b × h , then its TSA is ,
⇒ TSA = 2(lb + bh + hl)
⇒ TSA = 2[ (3)(5)+(5)(6)+(6)(3) ]
⇒ TSA = 2 [ 15 + 30 + 18 ]
⇒ TSA = 15 + 15 + 30 + 30 + 18 + 18
Hence the option A is correct .
Hence option (A) is correct.60 is 20 percentage of what number ?

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. Function g is a transformation of the parent sine function, f(x) = sin(x). g(x) = 1/3sin(2x - 5) +1 the phase shift of function g is ___.
The phase shift is C/B=5/2
We have given that the equation of the sine wave
[tex]f(x)=sinx\\G(x)=\frac{1}{3} sin(2x-5)+1[/tex]
What is the formula for the sine wave?The formula f(x)=A sin(Bx-C)+D
by comparing the g(x) above formula
Phase shift is C/B
C=5 and B=2
Therefore the phase shift is C/B=5/2

Answer:
133°
Step-by-step explanation:
angles on a straight line = 180°
180 - 144 = 36°
angles in a triangle = 180°
36 + 31 = 67
180 - 67 = 113
answer = 113°
Can someone help me please
Answer:
Substitute the 80°F where the F is in the equation. then just put the whole equation into your calculator. I got approximately 26.7.
In ΔIJK, i = 340 cm, ∠I=120° and ∠J=59°. Find the area of ΔIJK, to the nearest 10th of a square centimeter.
The area of triangle IJK is 999.8 square centimeters
The given parameters are:
[tex]\angle I = 120^o[/tex]
[tex]\angle J = 59^o[/tex]
[tex]i = 340cm[/tex]
Start by calculating the length of side j using the following sine ratio
[tex]\frac{i}{\sin(I)} = \frac{j}{\sin(J)}[/tex]
Make j the subject of the formula
[tex]j = \sin(J) \times \frac{i}{\sin(I)}[/tex]
Substitute known values
[tex]j = \sin(59) \times \frac{340}{\sin(120)}[/tex]
Evaluate the expression
[tex]j = 337[/tex]
Next, calculate angle K using the following sum of angles formula
[tex]\angle I + \angle J + \angle K =180[/tex]
Substitute known values
[tex]120 + 59 + \angle K =180[/tex]
[tex]179 + \angle K =180[/tex]
Subtract 179 from both sides
[tex]\angle K =1[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} ij \times \sin(K)[/tex]
So, we have:
[tex]Area = \frac{1}{2} \times 340 \times 337 \times \sin(1)[/tex]
Evaluate
[tex]Area = 999.8[/tex]
Hence, the area of triangle IJK is 999.8 square centimeters

Evaluate lim
[tex] \frac{3 {x}^{2} + 5x - 1 }{4 {x}^{3} + 2x + 6 } [/tex]
Answer:
[tex]\lim_{x \to 0} =-\frac{1}{6}[/tex]
Step-by-step explanation:
The first step in evaluating a limit should be to plug in the number to see if you get a result
When you plug in 0 to all of the x's in the expression, you are left with the constants -1 on the top and 6 on the bottom of the fraction.
So there's no need to go any further, the limit as x approaches 0 is [tex]-\frac{1}{6}[/tex]
Answer:
-1/6
Step-by-step explanation:
To find the limit as x approaches 0 we can just plug in 0
for the numerator: 3*0+5*0-1 = -1
For the denominator: 4*0+2*0+6= 6
answer is just -1/6 or -.16666666666666666666667

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given an expression as;
[tex]27^{-1/3} = \frac{9^{1/4} }{3^{r + 1}}[/tex]
Now we can see that
27 = 3³
9 = 3²
Then the power are 3(-1/3) = -1
3(1/4) = 3/4
So we have;
[tex]3^{-1} = \frac{3^{2/4} }{3^{r + 1}}\\\\3^{-1} =3^{1/2 -r - 1} \\\\3^{-1} =3^{1 -2r - 2 /2}\\\\3^{-1} =3^{-2r - 1/2}[/tex]
So,
-2 = -2r - 1
-2r = -1
r = 1/2
